Allen Walker/History

Early Life & Garvey Circus
Allen was abandoned by his biological parents because of the supposed deformity of his left arm (which was later revealed to be caused by his Innocence). He was presumably sold by them (or other people) to a traveling circus in which his deformity could be used as a freak show. But with Allen refusing to become a freak to entertain others, and his arm being effectively unusable he instead had to do odd jobs for the circus in order to survive. Having no name at the time, Allen was often referred to as "Red," in reference to his deformed left arm and the color of his hair. For the most part, Red was largely shunned and ignored by the circus troupe, with the exception of the clown, Cosimov. Cosimov was a jealous and sadistic clown who took pleasure in beating Red and would often blame Red for his mistakes. And with the new clown quickly gaining popularity over Cosimov, Cosimov's abusive behavior towards Red grew even more severe. One night, after after the show, Cosimov approached Red, chastisizing him for being "too gloomy" and demanding congratulations. As Red refused, they squabbled and Red gave the man a headbutt, making his mop fall and driving him crazy. As Cosimov started to beat Allen, the headmaster came in and asked explanations. Cosimov prettended that Red was slacking off, causing the headmaster to threaten the boy and remind him that he was his property. As the boy was fulminating against the circus and his condition, he glimpsed Mana the new clown, alone in the snow with his dog, singing an eery melody which made the boy shed tears. , Shortly Afterwards, after another trick of Cosimov Red met Allen, the dog of Mana. The dog stole one of the balls he was supposed to clean. After chasing him all around the circus, Red got exhausted and gave up. That's when the dog playfully came back with the ball that Red was still unable to catch. Finally Allen gave back the ball to Allen and licked his bruises. . But due to the jealousy that Cosimov held towards the dog owner (the new clown), Cosimov tried to kill the dog by intimidating Red into mixing broken glass into the dog's food. When Red refused, he was beaten by Cosimov again.

On Christmas Day, Red found the dog dead and lying outside the circus with its owner, Mana Walker, who is in grief upon discovering that his dog had been beaten to death. After grieving alongside Mana, Red finally learned that the dog's name was "Allen." Mana, who couldn't cry for Allen, thanked Red for crying in his place. When asked by Red why Mana would neither cry nor take revenge for Allen's death, Mana explained that it would only create more sadness which will lead the way to the Millennium Earl. Red, who didn't know the Millennium Earl at the time, didn't think too much of it. As Red continued to spend more time with Mana, he gradually began to open himself up to Mana's kindness. He even allowed himself to perform with Mana during a circus show despite his hatred of performing. That's when Cosimov revealed himself to be the culprit who killed Allen, causing Red to attack him in anger. But just before Red could land an attack on Cosimov, he is stopped by Mana who took the blow instead. Mana urged Allen to stop because revenge will only cause more sadness. However, Red, angered by the fact Mana took the hit for someone like Cosimov, continually beat Mana into a bloody pulp (with his hard, heavy left hand) for his idiotic kindness.

During all the commotion, Cosimov managed to fool the troupe into believing Red was the one who killed the dog. As Red is put into a cage, the Millennium Earl appeared with a legion of Akuma and slaughtered everyone in the circus. After escaping, Red found Mana covered in blood and mentally unstable. Mana kept calling Red "Allen", even when Red told him that Allen is already dead. Red realised that he must have damaged Mana's memories when he beat him, and was overcome with guilt. As Mana continued to refer to Red as "Allen" with a smile, Red swore that he'd become Mana's Allen and be by his side to repay and atone for the kindness that Mana has shown him. Thus, Red became known as Allen and they began to travel together as father and son.

Life with Mana
After travelling together for some time, Mana suddenly passed away. Allen, who was overcome with grief and sorrow, was manipulated by the Millennium Earl into bringing him back. Realizing that Allen has turned him into an Akuma, Mana cursed Allen's left eye, leaving a scar of the "Pentacle" (the mark of the Akuma) on the left side of Allen's face. Allen's left eye then gained the ability to see the trapped souls within Akuma. It was also at that moment Allen's left arm first invoked into an anti-Akuma weapon and instinctively destroyed his beloved father against his will. Before Mana was destroyed by Allen, he once again told Allen with all his soul that he loved him, causing Allen's bright red hair (brown in the anime) to turn stark white from the sadness and trauma. Afterwards, Cross Marian, a General of the Black Order, approached Allen and took him under his wings.

Cross's Disciple
Having killed his father with his own hands, Allen fell into a state of despair and refused to move or talk. He took Mana's death so hard that he simply gave up on living. During this vulnerable time, Cross nursed Allen back to health at his church with Mother and Barba. . After Cross encouraged him to fight on, spurring him with Mana's favorite motto; "Don't stop, keep walking.", Allen finally regained his will to live and spoke to Cross. However, in contrast to his original brash and negative personality, Allen became a polite and kindhearted child, imitating Mana as he remembered him.

Cross then introduces Timcanpy to Allen. With Timcanpy between his hands, Allen asks if people can befriend a golems and Cross replies that he can keep it for the night. Allen asks if He can become friends with Tim and Cross slams the door, claiming he doesn't care. From then on, Allen traveled with them with Timcanpy most of the time by his side: Sleeping with him as his pillow, carring him in a shoulder strap, watching him during the fights. [24]

Allen then resolved to become an Exorcist to atone for what he did to Mana, subsequently becoming Cross's disciple and spending the next three years training with him. During this time, Allen was tormented by his master's constant irresponsible behavior and is forced into playing cards and gambling, winning through cheating and deception, to pay off the debts that Cross accumulated. This, coupled with Cross' womanizing ways and harsh treatment towards him, led to Allen's fear of his master whom he never speaks fondly of. For Cross however, the abuse he constantly gives Allen is his way of getting back at him for all the time and effort he wasted taking care of him.

In the anime, While staying with Cross in India, Allen made a friend named Narain, who was working at the palace along with his sister, while studying to go into medicine. After one particular training incident, a depressed Allen went to see Narain, However, he found him grieving because his sister had died. Later Allen found out that Narain became an Akuma, but couldn’t think of killing his friend. Cross told Allen not to run away and fight to sever the chains of sorrow that bound Narain’s sister’s soul to the Akuma. After Allen successfully activated his arm and destroyed the Akuma, he found the experience painful, and Cross told him to get used to it, and to harden his heart to such pain in order to make it as an Exorcist. Just before being sent to the Black Order to become an official Exorcist, Cross knocked out Allen and abandoned him in India. When Allen recovered his master was long gone, leaving him to find his way alone to the Black Order.

Introduction Arc
Allen first appears in London with Timcanpy, who got eaten by a stray cat. Chasing after the cat, Allen wanders into a "cursed" church where he is handcuffed by a police woman named Moore. Soon after, Moore's colleague Charles is attacked and killed by an Akuma, leaving Moore unconscious. After taking her to the local police station, Allen is interrogated by the Britannic Police Inspector under suspicion of killing Charles. But with no concrete evidence, they are forced to let Allen go free. As the investigation continues, Allen is entrusted to Moore and is taken to her house. This is where Allen discovers that Moore's brother-in-law, Marc, is the Akuma that killed Charles. In truth, the Marc they see before them is actually Moore's late sister, Claire, who has take over Marc's body after being turned into an Akuma. Allen then explains to Moor the existence of Akuma and the Millennium Earl who creates them. When a person calls out to the soul of a dead loved one, the Millennium Earl can entrap that soul and bind it to his will. He will then force the soul to kill and take over that person's body and turn them into an Akuma. The only way to free the soul of Akuma is by liberating them with the Innocence. After a brief fight, Allen is able to destroy the Akuma and free Claire's soul from the Millennium Earl. He bids Moore farewell and continues his way towards the Order's HQ.

Reunion with the Millennium Earl
While travelling through a town, Allen hears someone screaming about Akuma and quickly rushes towards them. However, it turns out it was only a prank played by a local boy, Jan. But upon closer inspection, Allen's left eye is able to detect an Akuma and he quickly destroys it before it can harm Jan. After being asked about how he knows about Akuma, Jan reveals himself to be the son of a scientist who works for the Vatican. Allen then warns him not to poke into things like the Akuma and the Millennium Earl. Angry, Jan stuns Allen with an onion bomb that he created and runs back home. After coming back to his senses, Allen decides to find the boy again to try to convince him to stop pursuing the Millennium Earl. Upon arriving at Jan's house, Jan and his friend Leo manage to escape from Allen and head towards the cemetery. Allen quickly follows them after seeing that Leo is an Akuma. When Allen arrives, he finds the Millennium Earl with the boys, telling Jan that his friend Leo has been turned into an Akuma.

Allen quickly rushes towards Leo in attempt to destroy the Akuma. But not wanting Allen to destroy his friend, Jan gets in his way. Leo, now an Akuma, quickly opens fire upon Jan, who is in shock. Allen manage to protect Jan but had to take the hit himself. As Allen's skin begins to crumble under the Akuma's weapon, the Earl once again mocks Jan for being a weakling and how Allen has wasted his life to protect someone as useless as Jan. The Earl then explains that the ugliness of the Akuma is not his doing but the image that reflects the human heart. After dispelling the curse from his body with his Innocence, Allen proclaims that he can see the soul of Akuma. That's when the Earl realizes that he's met Allen before and Allen is the boy who turned his father into an Akuma. Allen, after reminding the Earl of his deed, engages in battle with the Akuma the Earl has summoned. Jan, finally accepting the fact that Leo can't be saved, pleads for Allen to destroy Leo. With that, the Earl retreats, and Allen deactivates his Anti-Akuma weapon and falls onto ground. Jan, who is in despair of Leo's death and the events that has unfolded, finds comfort in Allen's arms. After healing up, Allen bids Jan farewell and continues on his way to the Order's HQ.

The Order's Headquarters
When Allen arrives at the Order's HQ, the Gatekeeper mistakes him for an accomplice of the Millennium Earl because of the Pentacle Mark on his left eye. Kanda, who has just returned from a mission, quickly heads out to eliminate Allen. This misunderstanding is straightened out after Allen's letter of recommendation from General Cross is finally found on Komui Lee's very cluttered desk. With this, Lenalee invites Allen in and takes him to Komui, who offers to fix his anti-Akuma weapon, which was damaged by Kanda. After examining Allen's Innocence, Komui concludes that Allen is a parasite type. Komui then goes on to repair Allen's arm in a ferocious fashion, traumatizing Allen to a huge extent. Afterwards, Allen is taken by Komui to meet Hevlaska who predicts Allen to be the "Destroyer of Time". The meaning of this is never really explained, but Bookman theorizes that "time" refers specifically to the "millennium" or even more specifically, the Millennium Earl. In essence, it is believed that this prophecy means Allen will be the one to someday destroy the Millennium Earl.

After getting inspected by Hevlaska, Komui explains to Allen about the Innocence and the purpose of the Order. The Innocence was left behind by their predecessors who fought and won against the Millennium Earl 7000 years ago during Noah's Flood a.k.a Three Days of Darkness. However, the "Three Days of Darkness" will come again and it is up to the Order to stop it. To do so, they must find the rest of the 109 pieces of Innocence and guide them to their respective user before the the Millennium Earl finds and destroys them. After briefing Allen of his duty and welcoming him into the Order as an exorcist, Allen is sent to his room to await further orders. While in his room, Allen reaffirms his promise to Mana to never stop walking no matter how cruel and hard his path may be.

Ghost of Mater Arc
With Allen on standby, Lenalee Lee takes the opportunity to show him around the Order. Allen is able to meet many of the Order's members and quickly becomes familiar with the chef Jeryy due to Allen's huge appetite. But upon arriving at the kitchen, Allen notices that Kanda has started a fight with the Finders there, saying that Finders are useless runts that can't do anything but support exorcists. Before Kanda is able to strike a Finder, Allen intervenes and stands up to Kanda. This is Allen's second confrontation with Kanda which earns him the name Bean Sprout.

After being summoned to the head office, Komui gives Allen his first assignment: find a piece of Innocence in the town of Mater. Allen is partnered with a reluctant Kanda, and a Finder named Toma and they leave for Mater in Italy. Upon arrival, they discover that the Finders station in Mater is under attack by three Akuma and is on the verge of annihilation. Allen quickly joins the battle in an attempt to prevent any more deaths and attacks the Akuma who just turned Level 2. Kanda, who ignores Allen, manages to kill two of the three Akuma and secure the Ghost of Mater who contains the Innocence. With the Innocence secured, Kanda decides to head out first, leaving Allen behind to deal with the Level 2 Akuma alone.

Against a Level 2 Akuma with the ability to copy, wear, and shed people's appearance like a second skin, Allen is overpowered and crashes into the underground sewer of Mater. Guided by Timcanpy, Allen manages to arrive just in time to stop Kanda from killing Toma, who Kanda thought was the Akuma pretending to be Allen. In reality, the Akuma was actually pretending to be Toma and made the real Toma wear Allen's appearance as a trap. With Kanda tricked by the double trap, the Akuma is able to land a critical blow on Kanda. Allen manages to escape with Kanda and Toma to a safe spot where they coincidentally find the Ghost of Mater, Guzol, and his young companion, Lala. Overhearing their conversation, Allen realizes that Lala is actually the doll containing the Innocence while Guzol is merely a badly disfigured human. Unable to beat Allen in a fight, Lala pleads to him for mercy and tells him to let her be with Guzol before he dies. Allen, who sympathizes with both Lala and Guzol, decides to wait for Guzol to die before taking her heart. Kanda, however, demands that Allen take the Innocence inside Lala at once, arguing that if the Akuma were to take the Innocence because of Allen's foolishness, everything they sacrificed thus far would be for nothing. Allen proudly declares that if a sacrifice is necessary then he would gladly sacrifice himself to help Lala and Guzol fulfil their wish. For unlike Kanda, he cannot see the bigger picture and can only focus on that is in front of him.

The two continue to argue until the Level 2 Akuma arrives, taking Lala's heart, the Innocence, and gravely wounding Guzol. With Guzol and Lala's wish disappearing right before Allen's eyes, he becomes so enraged that his anti-Akuma arm transforms into two alternate forms. One in the shape of a cannon and the other a light saber sword. With his knew anti-Akuma weapons, Allen is able to gain the upper hand. But just when he is on the verge of winning, his Innocence rebounds as his body can't keep up with the morphed weapon. That's when Kanda decides to help despite their depute and they defeat the Level 2 Akuma together. Allen then tries to return the heart to Lala but she has already reverted back to being a mindless doll, who continues to sing to the already dead Guzol. As a tearful Allen keeps watch over the Innocence, Kanda reminds him that he is too naive, for exorcists are "destroyers" not "saviors." Allen sadly agrees but replies that he wants to be both. At that moment, Lala returns to her original self and thanks Allen for allowing her to fulfil her promise to Guzol before she broke. With tears in his eyes, Allen takes the Innocence from inside Lala and takes it back to HQ.

The Rewinding Town Arc
Allen and Lenalee are dispatched to a town in Germany that has been mysteriously stuck on the day "October 9" (October 28 in the anime) for thirty days. While investigating, Allen manages to save Miranda Lotto from an Akuma. But while they discussed the situation, they are attacked by three more Level 2 Akuma and are under a lot of pressure. The Akuma, however, leave them under mysterious orders despite having the upper hand. After investigating Miranda's life more, Allen and Lenalee figure out that Miranda's clock holds Innocence and that Miranda is the clock's compatible apostle. After figuring out that the time loop was caused by Miranda's lack of employment, Allen and Lenalee desperately try to help Miranda find a job. But before they can, the three of them are captured by Road Kamelot and held captive for her entertainment. As Road pierces Allen's left eye, Road reveals to him that she is a human and is a part of The Noah Family with direct ties to the Millennium Earl. Allen, who cannot comprehend why a human would side with Akuma, lashes out at Road. But since Road is a human, Allen could not bring himself to harm her. Seeing that Allen refuses to fight, Road tries to attack Miranda but is blocked by Allen. Seeing the injuries Allen suffered in his attempt to protect her, Miranda is able to find the strength to activate her Innocence, reverting Allen and Lenalee's injuries back in time. With their injuries gone, Allen and Lenalee work together to defeat Road and her Akuma. But to Allen's horror, Road forcefully commands one of the Level 2 Akuma to self destruct to prevent Allen from saving its soul. Horrified, Allen dashes forward in an attempt to save the soul by killing the Akuma before it detonates. Allen however, is stopped by Lenalee because the explosion would have killed Allen as well. Enraged, Allen lashes out at her for stopping him, but in response she slaps him. Road gets bored and decides to leave by opening up a portal. Just before she can, Allen points his gun at her. Knowing that Allen won't harm her, Road simply mocks Allen for being too nice before continuing into her portal. In the end, is unable to kill Road and is left to feel the anguish on his own.

With the battle over, Allen and Lenalee turn to Miranda who is still using her powers. They both of the notice right away that Miranda is straining herself to maintain the power. They ask her to deactivate her Innocence but she refuses. She tells them that if she does, all their injuries will return and she does not want to see them in pain after everything they've done for her. Allen then tells her that it's alright for her to release her power because she has already done everything she can. He explains that if not for her, none of them would have survived, and thanks her for her efforts. With that, the distraught Miranda deactivates her Innocence and both Allen and Lenalee fall to the ground as their wounds return. Miranda quickly contacts the doctor in town to care for them.

Bookman & Lavi
While recovering after the events of the rewinding town, Allen meets Lavi and Bookman who are also fellow exorcists. Bookman, a master of acupuncture, examines Allen's cursed eye, which had been stabbed by Road. To Bookman's surprise, the eye seems to be healing on its own but not quite enough for Allen to use it. After discussing a little bit about the Noah family with Komui, Lavi and Allen decide to go outside. When Lavi brings up the subject of the Noah family again, Allen conveys that he became an exorcist to destroy Akuma and not to kill humans. With his resolve of being an exorcist beginning to waver, Allen decides to walk downtown on his own. But while in town, Allen can't help but be suspicious of everyone around him since he is no longer able to use his cursed eye. Suddenly, an Akuma emerges from the crowd and attacks him, but he is saved just in time by Lavi.

Lavi then reminds Allen of the reason they wear their exorcist coats. Unlike Allen, Lavi and the rest of the exorcists do not have the ability to tell Akuma apart from humans. The only means they have of fighting the Akuma is to draw them out by wearing the Vatican uniform. Contemplating how hard it must be to live life suspecting everyone, and realizing that every exorcist but him has to live that life, Allen regains his resolve of being an exorcist and reminds himself of his promise to Mana - that he will continue to walk his path no matter how hard it is.

The Fall of the general
After returning from the town, Allen and Lavi are notified by Komui of General Yeegar's death. The general was found in Belgium nailed to a cross backward, with the words "God Hunt" carved into his back. Before dying, General Yeegar sang a same song over and over again: "The Millennium Earl is searching, searching for the precious heart. This time it wasn't me. Who will it be next?" Komui then explained to Allen that the Heart is a core piece of Innocence that serves as the power source for all remaining 108 pieces. Thus, if it is destroyed, all the Innocence will also be destroyed and humanity will lose all hope of defeating the Earl. Komui and Bookman conclude that the Millennium might be attacking the Generals first in the belief that the Heart's immense power would result in a powerful exorcist. As the Generals are usually travelling the world in search of new Exorcists, all unranked exorcists are divided into search parties and assigned the mission to find and safely escort them back to the Headquarters. Much to Allen's horror, Allen, Lenalee, Lavi, and Bookman are assigned to find General Cross.

The Leaf of Revival Arc
When a village begins experiencing abnormal, extreme weather conditions, the Order suspects that Innocence might be the cause. Allen, Kanda, and Lavi are assigned to find and retrieve it. On their way there, they find an old man and young girl unconscious in a snowstorm and save them by taking them to a cabin. Kanda decides to continue on by himself, leaving Lavi and Allen behind.

The next day, Allen and Lavi leave and search again for the piece of Innocence. They learn that the man Frey, and his daughter Elda, who had followed the exorcists, are travelling to obtain the "Leaf of Revival" and use it to bring back Frey's deceased son, as it is rumored that the leaves of the tree can bring a person back from the dead. At the same time, Skinn Bolic and Lero, along with three Akuma, decide to look for the Innocence fragment as well. The two exorcists begin to engage in a battle with the Akuma, with the Noah just watching from the sidelines.

Kanda arrives just in time to help finish off the Akuma, however, Allen collapses due to his injuries. Later, after Kanda and Lavi retrieve the Innocence from the Leaf of Revival, they are attacked by level 2 Akuma, however Allen arrives just in time to help. Working together, the three exorcists defeat the Akuma. Before departing, Allen warns Elda about the Millennium Earl, though Frey tells him he does not need to worry.

Millennium Swordsman Arc
Together with Lenalee, Allen is sent to look for Kanda, who was sent on a mission to retrieve Innocence but has not contacted headquarters for a week. Before getting inside the train, Lenalee argues with Allen, telling him that she hates his cursed eye.

As they arrive at their destination, they notice the town is filled with bounty hunters as Claudia, daughter of Mister Sardini, a local rich man, has been kidnapped by a man named Vittorio. After sneaking into Sardini's house, Allen has a conversation with Sardini, who reveals Claudia is engaged to Viscount Paletti. He also reveals that Claudia told him about a man who appeared to her during the night.

Allen and Lenalee head to the colosseum, where Akuma attack the bounty hunters. Vittorio appears and defeats many of the Akuma. But it is not long before Kanda also appears and starts fighting against Vittorio, only to get hit on his right side. Allen attacks Vittorio in order to stop him from killing Kanda. Soon, Claudia appears and orders Vittorio to stop fighting him and tells Allen to let her father know she doesn't intend to return home. Kanda is taken to the nearby house of an old lady, who tells Allen and the others about the story of Princess Sandra and Vittorio, that happened a thousand years ago. Sandra wanted to marry the strongest man in the world, so every man who wanted to marry her had to defeat Vittorio. However, Vittorio always won, and Sandra eventually fell ill and died. Yet, Vittorio kept fighting even after that. Kanda wakes up, hoping to complete his mission of defeating Vittorio before the Akuma get the Innocence. But Allen tells him to stay put and trust him, Lenalee and Vittorio to protect the Innocence.

Allen returns to the colosseum where Vittorio still keeps fighting Akuma. Vittorio challenges him to fight, but Allen tries to convince him that Sandra is dead and that his fight is long over. However, Vittorio denies this and attacks Allen.

When Vittorio is about to finish off Allen, Kanda arrives and stops Vittorio. He is struck again by Vittorio's giant sword, this time on his left shoulder. Kanda, however, uses this as an opportunity to cut off Vittorio's arm, so that he would let go of his sword which contains the Innocence. Allen goes to help Kanda as they witness Vittorio dying in Claudia's arms.

The Vampire of the Old Castle
After being assigned the task of tracking down the missing General Cross, Allen begins to have terrible nightmares of the difficult 'training' he endured under Cross's tutelage. He also notices that Lenalee has been ignoring him. When the train made a brief stop at a village in Romania, Allen followed Lenalee off the train then apologized for lashing out at her during their fight against Road. Lenalee tearfully berates Allen for his self-sacrificing tendency, reminding him that he doesn't need to bear the burden of the fight alone anymore, because he now has friends to help him. Lenalee then stormed away, apparently still miffed but having forgiven Allen. A bewildered Allen then made to rush back on the departing train, but he is suddenly grabbed by a nearby food vendor, who is later revealed to be the village's chief, and dragged away by the villagers then tied up.

Lenalee and Bookman sent Lavi to look for Allen when they realized he is not on the train, but he ends up being captured by the villagers as well. The villagers then explain to the trussed-up Allen and Lavi that their village's inhabitants are constantly threatened by a vampire by the name of Baron Arystar Krory III. Krory initially bolted himself up in his castle, which is filled with man-eating monster plants, and the villagers never strayed there for fear of their lives. Shortly before Krory started attacking the villagers, a traveler who wore an exorcist uniform went to visit Krory and came back unscathed. He told the village chief to seek the help of those who bear the Rose Cross insignia if there was ever a problem with the Baron. The traveler's prediction became true when Krory thereafter started his bloody rampage. The traveler is then revealed to be none other than General Cross himself. Though highly skeptical of the vampire story, as a significant clue to Cross's whereabouts, Allen and Lavi stayed behind to deal with the matter as Lenalee and Bookman go on ahead to wait at the next town. Lenalee, a believer in vampires, warns the two boys not to be bitten lest they turn into vampires themselves.

Allen and Lavi then entered Krory's eerie castle, accompanied by a hoard of villagers with torches and pitchforks, still denying the existence of vampires. Out of nowhere, Baron Krory rushes towards the villagers with incredible speed, snatching one, Franz, by the neck and began sucking his blood. Allen and Lavi quickly activated their Innocence and engaged Krory in battle. The fight culminates with Krory biting Allen's transformed left arm before fleeing with Franz's body, bemoaning that Allen's blood is "bitter". Lavi then teases Allen, joking that Lenalee will never speak to him again now that he's been bitten by a vampire.

After the villagers retreated in fear of Allen's transformation, Allen and Lavi enter the castle to rescue Franz. But instead of running into Krory, they run into Krory's giant man-eating flowers and his attractive assistant Eliade., who is on the way to bury Franz. Upon seeing their uniform, Eliade fed Franz to the flowers which then develop pentacle rashes before exploding violently, blowing Allen and Lavi outside to a small graveyard in the castle grounds, where Eliade usually buried Krory's victims. Upon closer inspection, they discover that Krory is not killing innocent people but actually Akumas in disguise, leading the pair to suspect that Krory might be an Innocence accommodator.

Meanwhile, Krory visits his late grandfather's portrait and laments his uncontrollable descent into monstrosity. Arystar Krory the First was an eccentric man, and the carnivorous flowers are actually his precious collection. He prevents Krory the third from leaving the castle, persuading him he is best off looking after his plants for all his life. Upon his death, he tasked Krory with taking care of the flowers, binding him to the castle forever, and Krory ponders whether his becoming a vampire is his grandfather's punishment for his curiosity to see the outside world, and bemoans that he is now reduced to nothing more than one of his collections, with no prove of his existence upon the world.

Krory was then alerted by Eliade of the flower's destruction, and went to attack Allen and Lavi after reluctantly drinking her blood to gain power. The two boys were overwhelmed by Krory's inhuman speed and strength and Allen was blown away into the castle, leaving Lavi to fight him alone and persuade him to become their ally.

Allen gets lost in the castle's secret passageways and was attacked by Eliade. Allen refuses to retaliate, telling Eliade that he has no reason to fight her, as they had not come to exterminate Krory but to recruit him as an ally, which Eliade derisively laughs at as she rained blow upon blow onto him. Allen then felt a strange dizziness and fell unconscious. Eliade prepares to finish him with an axe, but fails when his Innocence arm automatically moves to protect him.

Allen awoke in his subconscious to a faint illusion of Mana, and told him that he had decided to keep walking on the path of an Exorcist, alongside his friends, even without his left eye. Mana then faded away, telling Allen to "delve deeper into the world of black and white". Allen regains consciousness and realized that his left eye is functional once more. He discovers Eliade is an Akuma, re-igniting his will to fight. Eliade, who despises her grotesque Akuma form, reluctantly transforms and attacks Allen with full strength. The brawl sent both of them falling down to the main hall just as Lavi sent Krory smashing in as well.

Lavi reunites with Allen, and both him and Krory are shocked at the eerie sight of a human soul protruding from Eliade's body. Allen then learns that his curse has evolved and his eye is now able to project the vision to nearby people as well. Lavi reveals to Krory that Eliade is an Akuma, causing Eliade to transform and attack Krory, as she could not allow him to become an exorcist. Allen and Lavi made to help Krory out, but Krory's carnivorous flowers erupted from the ground and attacked them, separating them from the pair. As Lavi is about to be eaten, Allen recalls that the flowers are the same kind as Rozanne, a potted plant that Cross had him take care of with his life back when he was training. He tells Lavi the flowers will spare those who bear good intentions towards them, and the two proceeded to shower the flowers with confessions of love.

When questioned by Krory as to why she had not killed him long ago, Eliade reveals that she is simply using him to achieve something she had wanted to do. After berating Krory a coward for using his grandfather's will as an excuse to stay safe from the outside world, Eliade bombarded Krory with a hail of moisture-absorbing bubbles, leaving Krory's dried-up corpse to fall to the ground. Thinking she had killed him, Eliade converts back to human form and sadly watches his wretched remains. Krory's seemingly lifeless form then sprang up and bit her, sucking her blood to rejuvenate his body. In her last moments, Eliade confessed that she had simply wanted to experience love with Krory, as he is the only man she could not kill (as he bears Innocence), before dissipating into dust.

Having pacified the flowers, Allen and Lavi then approached Krory, who laments that he no longer has anything to live for now that Eliade is gone, and that he is a monster who killed someone he loves with his own hands. His words resounded with Allen, who had suffered a similar ordeal, and he reminded Krory that he must live on and keep destroying Akuma, so he will have a reason for destroying Eliade, stating that people can continue living for their 'reason'. In a reflection of his master, Allen also concludes that Krory, like him, is marked out to live as an apostle of God. Once Krory had calmed down, Allen and Lavi questioned him about Cross, and learned that Cross had visited Krory upon hearing news of his grandfather's death to return Rozanne, which he has been looking after for. After Cross borrowed a large sum of money and left for the far East, Rozanne bit Krory and then withers as Krory's teeth fell out, to be replaced with fangs. From that point on, Krory hungers for Akuma blood and starts attacking the villagers. Krory concludes that the plant must have been the 'Innocence' Allen and Lavi explained to him about. Spurred by Allen's words, Krory decides to become an exorcist and continue destroying Akuma, so Eliade's death would not be in vain. Before his departure, Krory set fire to the castle that had kept him caged for so long, signaling the end of his old life as his grandfather's collection and the beginning of his new life as an exorcist.

First Encounter With Tyki Mikk
Komui directs Allen and Lavi to simply take Krory along with their group instead of bringing him back to the Order, and the three boarded the train to meet up with Lenalee and Bookman. Allen also tested out the new abilities of his cursed eye; it can now detect any Akuma within a 300 meter radius, even from behind walls, and once concentrated, the eye can reveal the souls of Akuma to other people, and Allen realizes with dismay that his eye is starting to evolve just like an Akuma would.

Krory is deeply depressed about the villagers driving him away, refusing to believe Allen and Lavi's explanation, and went for a tour of the train under Lavi's advice. Allen and Lavi then went looking for him after he was gone for three hours straight, and found Krory wearing nothing but his underpants, having lost everything he had playing poker against three strangers, who had a boy named Eeez accompanying them. Realizing the men had scammed Krory, who knows nothing of the outside world from being isolated for so long, Allen challenges them in order to get Krory's stuff back. The normally unlucky Allen not only manages to get Krory's stuff back but strips the three men down to their underpants as well. Allen reveals to a bewildered Lavi that he was cheating. In what would be the first glimpse of his alter ego, "Black Allen", he proudly explains with an eerie laugh that in order to pay Cross's unpayable debts, he perfected the art of cheating "with (his) life on the line" and has never lost at cards since.

When the three men dismounted the train, Allen kindly returns the their clothes and belongings to them. To thank Allen, Eeez made to give the silver button he wears from his neck on a thong to Allen. The group's leader, a scruffy man in thick glasses, swiftly interrupts Eeez and gives Allen his deck of cards instead. After the train departed and the four prepares to leave for their next job, the bespectacled man receives a phone call and excuses himself, saying he has the usual "secret part-time job". As the remaining men leaves the station, the silver button that Eeez hangs from his neck flips over as he walks, revealing the name Kevin Yeegar embossed on the back, implying that the bespectacled man is behind his murder.

The bespectacled man then meets up with the Millennium Earl and transforms back into a Noah, Lord Tyki Mikk, then followed him back to their residence.

.

Order in Crisis Arc
Not long after the Cross Unit departed Romania with Krory in tow, the Order received an unprecedented attack from the Earl. Waves of Akuma succeeded in obliterating over a hundred Finders in Barcelona, while members of the Noah family appeared at various locations around the world, picking out and murdering six exorcists from the teams searching for Generals Tiedoll, Cloud and Sokalo. One exorcist, Suman Dark from Sokalo Unit, also goes missing. The Cross Unit only learned of the massacre when Lenalee talked to Komui on the phone, and, though thoroughly shaken, they continue their journey to find General Cross.

Lulu Bell's Attack Arc (Anime Only)
The Earl orders Lulu Bell to eliminate the exorcists Allen, Lavi, Lenalee and Krory who are searching for Cross Marian —she ultimately has to stop them from reuniting with Cross. She starts by disguising herself as Lenalee to lure in Krory and kill him but the other exorcists notice he is missing and go after him. When they meet up with him they find out that there are two Lenalees. As a result, the exorcists are separated, Allen and Krory, Lavi and Lenalee. When Allen and Krory get separated, Lulu Bell's attacks mostly focus on them. Some time later, the exorcists eventually reunite.

Suman Dark's Fallen Arc
Now that Allen's evolved cursed eye has completely healed, it has become a lot easier for him to spot Akuma, which makes it easier to fight them as well. Bookman and the rest of the crew, however, began to worry about Allen as he's been fighting twice as much as all of them combined ever since he got his new eye. Lenalee also noticed that his left arm is also "flaking" and jittery with fatigue.

After arriving in China and asking around about Cross, the exorcists are led to a brothel where they meet Cross's recent lover, Anita, who is actually a Supporter of the Black Order. The team are informed by Anita that Cross left for Japan eight days ago. But the ship that Cross was on was found in pieces in the middle of the ocean, indicating that he might have been killed. Allen, who knows Cross best, proclaims that Cross could not possibly die so easily. Seeing his determination, Anita regains hope of Cross's survival and directs her men to prepare a ship for the exorcists to set sail towards Japan.

While sailing, Allen soon discovers a huge wave of Akuma coming towards the ship. The exorcists ready themselves for battle, but they are surprised to see the Akuma simply fly over them without a fight. Upon noticing Allen, however, an Akuma carried him away by his left arm, prompting Lenalee to chase after him. The two then encounter the Akuma wave's true target; a gigantic white floating torso which expels enormous waves of light energy to destroy everything in its path, with a human half-embedded in its chest cavity.

A traumatized Lenalee recognized the monstrous form as a Fallen One, and the human victim as Suman Dark, a parasitic-type exorcist who had gone missing in action. She explains to Allen that she had once witnessed now-forbidden experiments in the Order, when the Order attempted to syncronize Innocence with blood relatives of deceased exorcists, believing this would increase the chance of synchronization. However, the synchronization would fail, and the Innocence will take over the human's body, forcing him to expel enormous power to drain his life energy and kill him, so it can re-synchronize with a new human. Since Suman is an exorcist fully compatible with his Innocence, Lenalee could not understand how he could Fall.

Resolving to save Suman, Allen and Lenalee flew up to the Fallen One and attempted to speak to an unresponsive Suman. A little girl then emerges from the Fallen's chest cavity and Allen pulls her out, only to be sucked in himself. As the Akumas continue to bombard Suman with bullets, Lenalee had no choice but to reluctantly leave Allen and take the girl, who is not breathing, to a hospital.

Over to Allen, Suman's memories begin to flow into Allen's mind, revealing to him that Suman's Sokalo Unit is attacked by the Noah Tyki Mikk. Seeing his friends overpowered and killed off one by one, Suman was overcome by terror and betrayed the Black Order to stay alive in hopes of returning to see his family. He made a deal with Tyki Mikk and called the Headquarters for locations of all the exorcists searching for the Generals, leading to the massacre in Barcelona and the murder of the exorcists.

Allen learns that after his daughter Jamie fell ill to an incurable disease, Suman reluctantly became an Exorcist to afford for her care. As per Order policy, this means severing all contact with his family and leaving behind the very daughter he tried to save.

However, by giving up fighting and making a deal with the enemy, Suman betrayed his own Innocence's will, causing his syncronization rate to fall below zero and resulting in him becoming a Fallen One. Desperate, Allen tries to convince Suman to separate himself from his Innocence before he burns his life up destroying another village in his path. To Allen's dismay, Suman doesn't listen and spits him out. In a last-ditch attempt to stop Suman, Allen activates his Innocence to its maximum invocation, which is far beyond his synchronization rate of 83%. With this, he manages to stop Suman's assault. However, his Innocence soon rebounded, leaving Allen screaming in agony as Suman again resumes his course toward the village.

A despairing Allen was spurred back into action by Timcanpy, and he activates his failing Innocence once again to stop Suman. Allen reminds Suman of his daughter and his desire to live and return home, which is strong enough to lead him to betray hundreds of his comrades, finally making Suman realise he wants to be saved. The two then work together to severe Suman's body from the Innocence in his arm and succeeded, both falling into a thick bamboo forest.

Allen's euphoria is short-lived, however, when he discovers that despite Suman's body being alive, his mind is dead; the Innocence having taken his mind as its last revenge after failing to kill him. Clutching Suman's spiteful Innocence in his hand, a tearful Allen moves to take Suman back home, still hoping to save Suman as his body is still alive. At that moment, Tyki Mikk reveals himself. Suman's body then explodes into a gruesome mass of blood and gore as Tyki calls out his carnivorous butterfly golems, Tease, from inside him. After agreeing to let him live, Tyki had planted a Tease within Suman's body so it could multiply as it feed on Suman's insides.

His Innocence broken and his body greatly weakened from forced invocation, Allen is powerless to defend himself from Tyki. Tyki reveals that he is on a mission from the Earl to search and eliminate people who has ties with a "certain person" (later revealed to be General Cross), one of his targets being Allen himself. After confirming Allen's identity, Tyki severed Allen's left arm and shattered his Innocence into dust to see if it would destroy Suman's Innocence as well, which would mean it is the Heart. Fortunately, Suman's Innocence remain intact. As his last attempt at resistance, Allen orders Timcanpy to flee with Suman's Innocence to Lenalee and Lavi before Tyki could destroy it, too. After ordering the Akuma wave to chase Timcanpy, Tyki inserts a Tease into Allen's body, telling it to eat a hole in his heart just enough for him to die from internal bleeding, as he believed "brave, noble" people like Allen should die a slow, agonizing death. After scattering the deck of cards he gifted Allen over his dying form, he left Allen for dead.

Edo and Asian Branch Arc
Inside his inner consciousness, Allen finds himself in a mysterious place surrounded by an endless field of ruins. From a distance, he can hear the cries of Lenalee. Hearing her call, he is determined to reach her. However, he is stopped by a mysterious shadow and awakens to find himself on an unfamiliar bed. Allen then hears someone's voice explaining that he survived Tyki's attack because his Innocence closed the wound in his heart. Though despite having survived such a dire predicament, Allen is in no mood to celebrate. All he can think about is Suman who he failed to save. Lost in his thoughts, Allen begins to wander aimlessly on his own towards wherever his body leads him.

Upon reaching the exiting gate, Allen is confronted by Bak who reveals himself as the leader of the Black Order's Asian Branch. Bak then tells him that without his Innocence, Allen would no longer have to live the life of an exorcist and no one would blame him if he choose to do so. Allen, however, refuses to give up his life as an exorcist because of his vows to his friends and to Mana. Seeing Allen's resolve, Bak reveals to him that his Innocence wasn't destroyed but reduced into particles and with training, Allen may be able to restore it.

Upon revealing that Allen's Innocence can be restored, Bak is attacked by For, Allen's savior and the Guardian Deity of Asian Branch. During this time, Allen is also introduced to others who work in the Asian branch, such as Assistant Branch Leader Sammo Han Won, Rikei, Shifu, and Lō Fwa. Afterwards, Bak leads Allen to the room his Innocence is stored in. But having been reduced into particles by Tyki, Allen's Innocence is in no shape to be invoked. Thus, Allen has to resort to training with For to restore it. But before the training starts, Allen accidentally discovers that Bak is a stalker of Lenalee with numerous pictures of her up his sleeves.

With a solution in front of them, Allen and For begin to engage in real battle training in an attempt to restore Allen's Innocence. Allen, however, is still unable to reactivate it even after days of training. Realizing that he's wasting precious time, which he could be using to catch up with Team Cross, Allen becomes frustrated and tries to push himself even harder. Seeing how distressed he is, For disguises herself as Lō Fwa to talk with him, reminding him that he fights not for the sake of fighting, but for something precious to him.

After encouraging Allen, a level 3 Akuma suddenly attacks the Asia Branch. Allen tries to fight back, but without his Innocence Allen is powerless to do anything. As a last resort, Bak decides to use For as bait so that Allen and the rest of the Asian Branch can escape. Refusing to leave For to die at the hands of the Akuma, Allen tries to persuade Bak to open the door so he can assist her. Bak, however, refuses to let up since Allen can't fight without his Innocence. This is when Allen proclaims he is an anti-Akuma weapon, accepting his fate as an exorcist and his destiny that ultimately ties to the Akuma. He implores Bak to open the door so he can once again be where he belongs—on the battlefield fighting against Akuma.

Seeing Allen's resolve, Bak has no choice but to open the door. With that, Allen quickly enters the battle in an attempt to save For. But upon seeing the Akuma and the soul trapped inside, Allen is reminded of the reason he chose to be an exorcist in the first place. He became an exorcist so that he could save the captured souls of Akuma. Having forgotten that, he now realizes why he couldn't invoke his Innocence. With the level 3 Akuma running amok, Bak tries to do what he can alongside Allen. All their efforts, however, are useless against a level 3 Akuma.

Just when For and Bak are about to be killed by the Akuma, Allen is able to invoke his Innocence to the form of "Crown Clown" by accepting who he is; his left hand is for the Akuma he promised to save and his right hand is for the friends he swore to stand together with. And with his new anti-Akuma weapon, Allen is able to defeat the Akuma, saving For and Bak's lives. Before destroying it, Allen learns from the Akuma of the situation in Edo and that Allen will be able to travel there by using Noah's Ark, the same device that let the Akuma into the Asian Branch. When Allen asks why the Akuma would tell him all this, the Akuma replies that he doesn't know; it simply felt right to tell him everything.

Noah's Ark Arc
After healing up a bit, Allen uses the Noah's Ark to reach Edo just in time to save Lenalee from the Earl. With his new Anti-Akuma weapon, Allen fights the Earl but it ends in a draw and the Earl retreats. However, Kanda charges toward Allen, thinking he is an Akuma summoned by Tyki, however Allen stops him from attacking at the last second. Kanda simply gets mad in response and they begin their usual routine of trading insults with each other.

Now that Allen has caught up with the others, his emotional reunion with Lenalee is interrupted as Lero teleports Lenalee away. Allen, Lavi, Krory, Chaozii, and Kanda, are teleported together with her into the Noah's Ark when they try to pull her back. As they investigate their surroundings, Tyki appears and gives them a key to Road's dimensional door so they can escape the collapsing Ark. When the group uses the key to open one of the doors in the area, they encounter Skinn Bolic and Kanda forces Allen to lead the others ahead while he stays behind to deal with Skinn.

After opening the next door, Allen finds Jasdevi in their split form. Allen, Lavi and Krory fight against Jasdevi, but the twins reveal Cross left them with a debt of 100 guineas. The twins want Allen to pay the bill, but Allen maintains what they owe is nothing compared to what he has had to pay on Cross's behalf over the years.

Angered, the twins steal the key and force Allen's team to search for it amongst a room full of duplicate keys, which are actually just an illusion. Allen gives Lavi time to find the real key as he and Krory fight off Jasdevi. Allen becomes angry as Jasdevi attacks Lenalee and Chaozii, and thanks to Krory's ability to sense Noahs, they are able to restrain the twins until Lavi finds the key. With this, the twins merge into a single body, after being called kids. Krory forces Allen to lead the others out of the Ark so he may deal with Jasdevi alone.

As Allen helps Lenalee up the stairs, the exorcists discuss what they will do after the battle is over. Allen tells the group he will eat everything that Jeryy can cook and that he will never give up hope. With this, Allen's team runs into Road and Tyki at the top of the tower and Road surprises all of them by kissing Allen on the lips. Tyki asks them to sit down for a meal but Allen refuses to eat without time to enjoy it. Tyki then tells them to look outside and they see that everything except for the tower has been destroyed. He then asks them if they are afraid. A short time later, a fight ensues between Allen and Tyki when Tyki sends the Teez to kill Lenalee.

Allen and Tyki's battle reaches a point where Allen's new arm breaks. But he reveals to Tyki that it is the Innocence that provides the power but it is the exorcist's heart that makes him deadly and with that his Crown Clown heals itself. In retaliation, Tyki repels the air to create a vacuum to kill Allen. Allen attempts to break free from the vacuum by synchronizing with his Innocence. As Tyki is about to pull out his heart, Allen decides to use his power to save humans as well as the Noah, and is able to reach critical point, which is achieved by exceeding 100% syncronization rate (which is the requirement to become a general). This results in him being able to use Crown Clown's Sword of Exorcism. Allen unsheathes his new Sword of Exorcism and with it, he is able to exorcise the Noah from Tyki.

Road is enraged when Allen exorcises the "Noah" inside of Tyki and gets revenge by using Lavi to attack him. Lavi is eventually able to overcome Road and manages to defeat her. As they escape, Allen tries to save Lero and Tyki. However, after they realize that Allen's attempt at exorcising the Noah failed, Tyki becomes a fully awakened Noah and turns into a demonic knight that easily overpowers both Allen and Lavi, until General Cross arrives to rescue them.

Later, Cross orders Allen to control the Ark, and sends him and Timcanpy into the secret room of The 14th Noah, where Allen faces a dark apparition in the mirror who calls Timcanpy "My Timcanpy". Timcanpy projects a mysterious set of music scores, and Allen begins to play on the white piano, at the same time thinking of his wish (to give back his friends), controlling and restoring the Ark. With the Ark, they take the Akuma Egg to the Black Order Headquarters.

Invasion of the Black Order Arc
Since Allen has the powers of the Musician, which allow him to control the Ark, he is able to save his friends. Moreover, this also allows him to stop the Akuma egg from being downloaded, meaning the Earl will be unable to make more Akuma.

Later, Allen wonders about how the symbols he and Mana created years ago were the song to control the Ark. He tries to confront his master about it, but he never gets the chance to. After Allen and his friends return to Headquarters, he is put under supervision by Malcolm C. Lvellie, who wants to put Allen on trial for treason. In order to ensure Allen's loyalties, Lvellie has his subordinate, Howard Link put Allen under 24-hour supervision. This causes many members of the Order to suspect Allen while close friends, including Komui, Lenalee, Lavi, Bak, Reever, and Johnny, believe that Allen would never betray them.

The Noah, Lulu Bell, brings her army of Akuma and Skulls to attack the headquarters' Lab 5, where the Akuma Egg is being studied. The army injures the entire science department, intending to turn the smart ones into Skulls. Allen and Bookman arrive through the Ark, and struggle against the endless army of level 3 Akuma.

By this time, Lulu Bell has already secured the Akuma Egg and opens a gate to the Millennium Earl. Allen returns just in time, jumping into the fray to rescue Miranda, who had been on the Egg, as the Generals begin their attack. The Egg is destroyed by the Exorcists' combined efforts when Lulu Bell attempts to take back the Egg again. The victory is short-lived, however, as a level 4 Akuma appears and easily pummels Allen, going on to lay waste to a portion of headquarters. When Allen sees the level 4's soul he starts to vomit, believing it to be too grotesque to look at. Allen, along with Lenalee, with her new form of Dark Boots, overpower the Akuma. Eventually, the generals join in and pour their full power into their attacks, finally defeating the Level 4.

After the battle Allen is unable to move, and before he is crushed by falling debris, Howard Link saves him and takes him to the medical ward.

Destruction of the Black Order Arc
Allen and friends are helping move the science team's storage when a massive storm hits the Black Order's Head Quarters, causing a blackout. Unknown to them, someone or something has infected Krory with Komuivitan D, a mysterious substance created by Komui to combat overworking the science team. The Komuivitan was deemed dangerous, as it seems to turn the person who drinks it zombie-like, infecting others with Komuivitan D via biting. Soon enough, most of Head Quarters is infected with Komuivitan D, save for Link, Lavi, Kanda, Allen, Johnny, Lenalee, Bookman, Marie, Reever, some others of the science team, and Komui.

Eventually, however, in an effort to try and create a vaccine from the original source of the entire infection, everyone but Johnny, Allen, and Komui is infected by the oncoming horde. Johnny and Allen are infected as well, but not without finding out that Krory is the source of the infection. A ghost in the Head Quarters is to blame for giving Krory Komuivitan. Komlin EX is creating a successful vaccine from Krory's blood, but unfortunately, Komlin is destroyed when Krory gets infected by Allen and Lavi after being so overjoyed at seeing them that he doesn't realize that they are affected by Komuivitan D. Komui is infected as well, but luckily, the next day, Bak comes to visit and cures Head Quarters of the Komuivitan D infection after finding a vaccine.

Disappearance of Cross Marian Arc
They move to the new headquarters and Allen is charged with putting ark gates to facilitate the transporting. After he finishes he is thanked by Lvellie who tells him to follow him.

Cross arranges a meeting with Allen and reveals to him that he is to become the 14th Noah. Allen asks what the relationship was between Mana and the 14th. Cross replies that they were brothers. Cross apparently was looking after Mana for the 14th. He tells Allen that at the right moment he would someday lose his very soul to the 14th who would be reborn in his body and also that he was doomed to kill the "ningen" or "human(s)" he loved when that happened. Allen was probably very worried, but has since recovered a cheerful front and is trying to keep his mind on his duties.

While at the Black Order's new HQ, Cross Marian is attacked and killed. His killer is later revealed to be the unnamed Cardinal, who reveals himself to be Apocryphos, which shows a cutscene of his killer holding Judgement to Cross's head before it was fired. This cutscene was apparently Cross's killer's memories that were accidentally shown to Allen while being attacked. Cross's guards fell asleep during their watch, which is how they don't realize that an intruder has entered Cross's room until it's too late.

Witnessing Cross's bloodied body, one of the guards run off to get Inspector Lvellie. The other guards bursts into the room, only to find that Cross's body has fallen through the window, leaving his shattered mask behind on the seat. Cross is never found after this, and during the investigation of his room, Timcanpy seems to sense his master's demise and flies to his room. It is then that Allen discovers his master's tragic death.

A reunion is hold between the exorcists and Allen demands to be killed if he ever becomes the fourteenth. But he assures his friends that this won't happen.

Months later, Allen is sent on a mission with Kanda and Miranda. They go to a cemetery to retrieve an innocence kept by the ghost of chess champion Mister Martin. Helped by his sister, they all face the former champion at chess but are defeated. Allen is charged with defending the area while Link is playing. He saves Miranda from a level 3 akuma. Link wins the game and they return to the headquarters with the innocence ring. To pass they have to give a code to Father Frederico.

Later, Timcanpy returns to the room where Cross has disappeared. Allen follows him and finds Lvellie sipping tea. Lvellie proposes him some cake but Allen ignores him and tells Tim that they're leaving. Lvellie asks Allen if he is the one who killed Cross. Upset, Allen replies that it may be Lvellie who did it and slams the door.

Phantom Thief G Arc
He is sent on a mission with Kanda and Marie to investigate a strange rash of theft. They first visit the captured victims in the jail and leave to capture G. Later that night, G steals the crown and Kanda intercepts G but is revealed to be another victim. As G escapes, Allen ambushes him and reveals that it was part of their plan. However while Allen was distracted, G possesses Link. Link proves himself formidable to match Kanda. Kanda reveals that Link is a CROW of the Central Agency.

Allen stabs Link with his Sword of Exorcism and G is in shock. G begins to cry in a very unique way that Marie used to find the source. Marie has lead his team to a boy named Timothy whose Innocence can allow him to control other people's bodies. The building is suddenly dark and Allen realizes that his eye isn't reacting at all to the Akuma even though it is in front of him. The Level 4 tells him that he shouldn't underestimate the Earl and that they have finally caught up with him. Allen also attempts to summon the Ark but this too is disabled inside the barrier. He then engages in battle with a second Level 4 Akuma and three other Akuma who are attempting to take the boy. Although Kanda manages to injure the Level 4, Allen loses his sword when the Akuma grabs and throws it away. After running from the attacks, he calls Crown Clown back to him, making it fly straight through the Akuma and through himself, pinning them to the wall. As the Akuma comments on him skewering himself and Allen explains the effect of the Sword of Exorcism, but is suddenly wracked with pain as the Sword seems to be affecting himself as well. As the Akuma prepares to fire on him, the 14th Noah inside him surfaces. He touches the Akuma's cheek, causing it to stop, saying only "Good Morning". Sensing the 14th inside of Allen, the Level 4 starts to cry, and it is skewered by Kanda just as it was able to pronounce "Noah..." Allen, who seemed under the 14th's control, looks at Kanda with a hostile expression. Kanda then provokes Allen by calling him "Idiot Bean Sprout". Allen's conscience immediately surfaces and they slice the Level 4 to pieces.

Artificial Exorcists Arc
Upon his return to Headquarters, Allen has a dream in which he is impaled on the Sword of Exorcism and a voice tells him he is not without sin and that it is he who is in need of salvation. Mana appears in the dream and invites Allen to come with him - though he never calls Allen by name. He uses another name that Allen can't quite make out, symbolized by ***, three unknown characters. Allen asks Mana to call him by his name and then wakes up. His hair turns wavy, with slitted, hostile eyes. This startles Lenalee, who had fallen asleep on the bed next to that of Allen's. Allen seemed not himself -highly likely he was under the 14th control- until Lenalee calls his name. Before the two could start a conversation though, they are interrupted by Link who has been unable to perform his duties because of Lenalee's "immodest state". Allen tries to lock him out for a moment, while Lenalee asks him whether or not he is feeling alright. Link threatens to tell Komui that Allen is alone in a sealed room with Lenalee. Allen immediately relents and opens the door. Later, Lenalee is shown thinking that Allen looked like a different person when he woke up. In Jordan, Allen and a few Third Exorcists begin fighting an army of Akuma. There, Allen sees what happens to Akuma souls when Third Exorcists absorb them, and his eye bleeds from it. After that, Tyki appears with some other Noah and began to attack, while taking shelter in a cave, Allen learns the fate of any Third Exorcist but Tyki reappears to battle them. Allen manages to defeat all the Akuma and disappears and reappears to where the Noahs are keeping the Order hostage. Allen comes from an ark gate beneath a black coffin ready to attack the Noahs but the Earl is waiting for him. As they meet, Allen and Tyki both manage to land on the Earl without seeing him. The Earl grabs Allen and tells him that he'll never go back to the Order, as he'll be leaving it by choice soon. As the Earl questions how he called him by saying "Good Morning" the Level 4 Akuma in the Timothy arc, Allen denies trying to contact the Earl. The 14th, however, appears, and makes a death threat, saying that he'll take over the Earl's place. During this, Allen goes through great pain, as if he were about to transform into the Noah. After managing to recover, Allen informs the Noah, the Earl, and the 14th, saying, "I'm Allen, an Exorcist! And I'd die before becoming anything else." He also says, "Don't take your brotherly fights out on other people! It's a nuisance!!" to the Earl, and especially the '14th'. Wisely then hints at Alma's existence to Allen, and after Alma is brought out, he draws Allen and Road into Kanda's memories. He sees the younger Alma, who says "Raise your hand if you understand me." and does so, only to be stomped across. He realizes that Alma doesn't appear to notice him, and sees a hand rising from a circle of water. That hand then turns out to belong to a naked boy that gets pulled out by Alma. As he's finally pulled out Allen realizes that the child is Kanda. After that Allen watches Kanda's memories as he was involved in the "Second Exorcist Project". The Second Exorcists seem to be killed exorcists whose brains were transferred to artificial bodies. The scientists tried to transfer Innocence to those artificial bodies. Allen witnesses those painful memories and is almost consumed by Kanda's emotions, until Road explains to him that he's seeing Kanda's memories. In these memories Allen learns of the relationship between Alma and Kanda who were both part of the painful and cruel experiments of the Asian Branch, always fighting (and after that always regenerating and healing their wounds due to their modified bodies). Allen also witnesses Alma eavesdropping on the scientists who intended to kill Kanda, because he seemed to have dreams of his real memories as an exorcist, and then tried to save his only friend and almost got killed by the CROW in the process. In the end Kanda thinks Alma is dead and survived himself.

After watching Kanda strike Alma down and having endured Kanda's memories long enough, Allen blows his top and punches Kanda in the forehead with his Crown Clown for allowing Wisely to "spy on his memories" for so long and forgetting his quick temper. Road notes that it's cruel of Allen to strike someone in the head with Innocence but he's also too late. Johnny and Bak begin to call to Allen telling him to stop Alma Karma before he wakes up and turns into an Akuma. Allen stares shocked at the demonic cocoon containing Alma but before he can react, the Earl tells Alma to "kill them" and Alma's awakening causes a huge explosion that blows up the entire North American Branch. Allen survives, noticing Kanda is confronting Alma, but is shocked that Tokusa used his seals to protect him from most of the blast, despite his injuries. Allen begins to feel guilty that he couldn't save anyone at the time, a thought to which Tokusa knees him on the head, saying that being an Exorcist does not mean he can save everyone. Allen is then relieved that everyone is probably safe when Johnny contacts him. As Alma begins to turn into an Akuma, Allen witnesses Tokusa mutating. Allen attempts to help Tokusa, but is blown away into a wall. Then Allen's Crown Clown activates by itself and forces Allen to use Edge End on Tokusa. Allen begs for the Innocence stop threatening to kill himself with it if the Innocence didn't obey him, but Tokusa approaches Allen. Allen then watches Kanda fight Alma, and asks why Kanda is fighting so seriously to use Four Illusion Style. Tokusa then sneaks up behind him and attacks him, while claiming that he is not an enemy of Exorcists to stop himself, but is struggling. Then the Millennium Earl requests Allen to come along with the Noah Family as the Fourteenth if he wants the Earl to "put an end to this little show".

Allen watches as Tokusa and Alma terrorize all of his comrades present. He tries to call to Tokusa, who no longer recognizes him as he's consumed by Alma's hatred. Tokusa then proceeds to break his leg. He's saved by Bak using "Sealed God" and Fō also comes to his aid, sealing him in a bubble with her. When she sees him looking conflicted, she asks him is he really thinking about taking the Earl's offer. He replies he understands Alma's hate from the memories shown to him by Wisely but doesn't see a way to save him. They're then attacked by Tyki who injures Fo. He then extends his hand to Allen, telling him not to irritate the Earl any further. Fō yells at Allen for being a fool trying to save everyone, telling him it's not that easy and he can't go deciding on his own. Tyki casually blasts her but Allen saves her with his Sword of Exorcism, asking whether she thinks he can save him. He begins to fight Tyki but Fō tells him she'll take care of Tyki. Allen goes off to deal with Alma but his leg hinders him so Professor Zu heals him with his magical golem "Atuda" using his own life force. Allen then stops Kanda from attacking Alma with his "Fifth Illusion."

Allen blocks Alma from Kanda's "Fifth Illusion" attack telling Alma to get back more. Later Allen starts mocking Kanda because of his appearance, more later asking Kanda why he stabbed Alma. Kanda then uses "Fifth Illusion Ripping Flash Claw" on Allen and Alma. It is later said that his hair has turned light purple because he sublimated his soul too much to the "Fifth Illusions Form". Kanda using "Fifth Illusion Ripping Flash Claw" is shown to affect Allen badly. Later on, Allen and Alma are still fighting as are Fō and Tyki. Alma is later shown attacking Kanda with a strong attack but Allen blocks the attack with his Innocence, telling Alma "You should have seen, just like the Noah showed me... The reason why Kanda chose to live nine years ago.. You still won't forgive him?!" Allen is shown holding Alma up by his tail, Alma also starts crying saying "As long as Yu's still alive, I..."

It is shown that the Akuma Alma's regenerating ability has reached its limit, Allen is holding Alma from falling but when Kanda attacks Allen moves Alma out of the way not giving Alma to Kanda who wants to kill him. Kanda is later telling Allen that it's his fault Alma is an Akuma, also telling him "The one who destroyed this branch and made the Third Exorcists into monsters is all your fault, the fault of the man who belongs to the Order even though he's a Noah!" Allen's Innocence activates then he attacks Kanda, screaming Kanda's name. While Kanda screams "It's all your fault, you fucking Noah!" They continue fighting until Alma shoots light at Allen hurting him in his shoulder, crying while doing it.

But Allen still attacks Kanda asking Kanda "You think destroying Alma is going to end everything!" When Kanda stabs Allen right in his stomach with his Innocence, the Earl is shown being happy. Kanda finally regains himself with Allen asking Kanda "Look carefully at Alma's face. Why is he making that kind of face?" The area around where Kanda stabbed him starts to change into the color of a Noah's skin, eventually spreading throughout his whole body. Allen then pushes away from Kanda and falls to the ground showing that his whole body looks like a Noah's, Kanda calls him Bean Sprout as he falls down. Reever from the Black Order than says "His body looks like a Noah's..." After Kanda wounded Allen with his Innocence, The 14th started to awaken. Inside Allen's mind he is chained to a structure and confronted with the 14th. The 14th says that the Earl is going mad and that the Earl and Allen are both puppets. Allen mistakes the 14th for Tyki and then the 14th corrects him and introduces himself as Nea. After Timcanpy destroyed the barrier an image of Mana appeared which stops the take over. Allen's left eye activates and then he saw a woman's soul in Alma Karma's body. Angered by this, Alma's hatred reawakens and once more attempts to kill Kanda by activating his self-destruct. The detonation blows Allen back and creates a crater. Kanda is seen on the brink of death and crumbling to pieces.

Allen arrives back at Kanda's body just as Alma's body begins regenerating. Alma begins to crawl as he searches for Kanda's body, saying that he "wants to be by his side." Allen picks up Alma's body in an attempt to bring him to rest beside Kanda. As Allen is carrying him, the dark-matter once more takes over Alma's body in an attempt to consume Alma's soul. Kanda tells Allen to send both he and Alma to "the place where we had our first mission together", referring to Mater. Allen agrees and sends them both through an Ark Gate. Allen than declares to the rest of the people witnessing the event that he cannot allow the Noah nor the Church to get in his way any longer.

Meanwhile, the Third Exorcists are still whirling out of the control, and the Exorcists are forced to battle and kill them. Allen attempts to suppress Tokusa without killing him. As the Order members verbally apprehend Allen for letting Kanda and Alma escape, Allen refutes that they could save the Third Exorcists, and questions if the Order truly intends to destroy the Third Exorcist Project. The Earl states that the Third Exorcists that are still rampaging show the long grudge Alma had for the Organization. Rouvelier then barks an order to go find Alma and destroy his body to stop the rampage, but Allen persists, prompting Rouvelier to declare that Allen is no longer an Exorcist. Allen continues his attempt to persuade Tokusa, telling him that he isn't Alma, and that only Alma's cells are causing him to rampage. Because it is Tokusa's body, he should be able to control. But Tokusa asks Allen why he bothers to even save him if Allen should just kill him. Allen then asks back why the Third Exorcists are giving up so easily, and coaxes Tokusa into suppressing Alma's rage. However, Link arrives carrying Tewaku, and restrains Allen with seals, mistaking Allen for trying to kill Tokusa. Tewaku transforms and tries to attack Allen, but Timcanpy appears as a huge monster and saves him in time.The Earl whisks away Tokusa and the others for his own uses, declaring that he will return for the 14th Noah. Allen is shown to be imprisoned along with Timcanpy.

Seed of Destruction Arc
Knowing he is held for treason but not yet put to death so he can be questioned, Allen becomes very paranoid and refuses to eat, fearing truth serum has been slipped into his food. He's purposely unresponsive to interrogations, and seems intent on retreating mentally. Because of his actions, priests from the Vatican have taken to drawn-out forms of torture, leaving the worst of his wounds, the stab through his stomach he received from Kanda, largely unattended to.

It is only when Howard Link makes him accept food sent by Jerry (which has a slur aimed at Rouvelier scrawled on top, thus proving no one has tampered with it) that Allen begins eating. Allen then apologizes to Link.

Link is rather annoyed that the first words out of Allen's mouth are an apology, but reveals his shared past with the Third Exorcists. Allen regrets not having become better friends with them, and wishes he had known more about the situation. He also thinks Kanda and Alma could've survived if he had had more knowledge, and realizes all he's doing is hating without knowing anything about the 14th. He then begins to think about the 14th, wondering if he knew more, if something would change. Somehow, these thoughts awaken Allen's inner Noah, and Allen begins to lose consciousness. As Allen comes close to passing out, a cardinal from Central enters his cell and claims he's going to 'heal' Allen. Link, though surprised that the cardinal is there, allows him to approach Allen, only to be shocked when the fingers of the cardinal's left hand unfurl into dangerous-looking feather-blades. The blades pierce into Allen's innocence and cause him great pain. Link tries to intervene, but the cardinal attacks him and erases Link's memory of the cardinal. Allen attempts to stop the cardinal and pierces his head by accident with his innocence, as his vision was blurred and he couldn't move well. The cardinal is unaffected by the attack and begins moving towards Allen. The cardinal continues what he was doing earlier, and Allen sees a vision of his Master, on the night that he went missing, and he was confronting the cardinal.

Tyki Mikk (sent by the Millennium Earl) intervenes and temporarily disables the cardinal by smashing the Cardinal's head into the floor. Road appears in her doll form and reverts back to her Noah form upon seeing Allen. She comforts him, since he is incredibly shaken by what he saw of his Master. It is then revealed that the cardinal is in fact an independent innocence known as Apocryphos, which exists solely to guard the Heart, and to do so is intent on absorbing Allen, as it is "what his (Allen's) Innocence wants". After a brief struggle between Apocyphos and Tyki, Allen attacks it claiming that the thought of merging with the person who killed Cross sickens him, and either blacks out and is taken by Tyki and Road, or willingly goes with them. Either way a message is broadcast across the Black Order that he has left with the Noah and his status as an Exorcist has been suspended. After having a small argument with Tyki which ends in Tyki saying Allen has "two monsters" inside of him (his Noah memories, and his Innocence) and as a result "sows chaos and creates conflict" wherever he goes. However, before Tyki leaves, he tells Allen to show his monsters "who's boss." Road wakes up from an apparent coma-like state and says that the inspirational phrase Mana gave to Allen in the past, "Don't stop. Keep walking," was originally said by Nea to Mana. Road adds that Nea fought to protect Mana, then disappears. Absorbing all of this, Allen decides to follow his own path without the Noah and the Order and opens a portal, via Ark. Just before he steps through to leave, Lenalee catches up to him and begs him not to go because if he does it means they will have to fight each other. Allen hugs her and assures her that he will always remain an exorcist even though their paths may be different. Before he leaves, he tells Lenalee that he loves her and everyone else at the Order, and that he will always consider the Order his home. He then walks through the Ark Gate, which crumbles after him as Lenalee falls to her knees and screams after him in sorrow.

Searching for A.W. Arc
It is then revealed how Cross took care of Allen after Mana died, and current Allen is seen returning to this place. There he meets Barba and Mother who are overjoyed to see him. He retrieves his clown stuff and departs. During his mare, Allen has been surviving by doing clown performance as well as gambling (and cheating). Because of his "winning methods" namely to the detriment of mafia bosses, Allen was banned from more than a few gambling houses. Three months later, he is found lying in an alley in an unknown city by a young girl while emitting feathery-tendrils of Innocence from his body. When she asks if he is an angel he quickly places a finger in front of her mouth to make her stop talking. It is revealed that he is still being tracked by Apocryphos, who has just arrived at the train station.

Some time later he is seen performing a street show in his clown outfit and sees Johnny, which shocks him. He quickly and silently approaches him with his hat for money and then gets even more surprised to see Kanda, who approaches Johnny when the latter discovers they lost all their money. Johnny leaves to earn some money while Kanda stares at a terrorized Allen, who averted his gaze last minute (to keep Kanda form seeing his face) by doing more tricks. Kanda declares he wants to "slice him up a little," but Johnny drags him away, relieving Allen. However, his eye activates and an Akuma attacks from below. Kanda tries to destroy the Akuma, but it explodes as Allen emerges with his Innocence activated in front of the duo. When Johnny tries to hug Allen, he pushes him away and tries to run for it. Kanda pulled him down and used Johnny's cloth to wipe Allen's face make-up. Akuma started to appear in the middle of Allen's argument with Kanda, and in the middle of the battle, Allen was questioned by Kanda of Howard Link's death, taking Allen by surprise. Allen became furious when he figured out that it was Apocryphos who murdered Link. When more Akuma arrive, Allen tries to get away because he knows the Akuma are coming for him and they were fighting in a crowded street. When running away, Wisely and Tyki taunt Allen, saying they will use Allen "as bait for Apocryphos". Suddenly, the 14th starts to resurface, much to Allen's dismay.

While attempting to get away from Johnny and Kanda, Allen starts to lose control to Nea and takes refuge underneath a stone bridge, not knowing that Johnny had implanted a tracking device in his hair when he had hugged him. Allen gets angry when Timcanpy suddenly bites his head, not knowing that the golem is trying to eat the tracking device, and then Allen's pain suddenly worsens, and the panic of losing to Nea starts to make him paranoid. He then hallucinates someone similar in appearance to Tyki asking him (Nea) if he hates him, and before the hallucination can go any further an Akuma emerges beneath Allen. Before it can attack, Kanda and Johnny catch up, Kanda defeating the Akuma while Johnny tends to Allen. Allen snaps at them both, refusing to let them touch him, and then turns his anger on Kanda, demanding to know why he came back rather than staying with Alma. Kanda's heated answer makes Allen realize that Alma has died, which makes him cry before he collapses in pain. Kanda realizes that the wound that is bothering Allen is the one he had caused with Mugen at the North American Branch, and Johnny sees that his Innocence is trying to heal it, as it had when Tyki had punctured his heart.

When Allen falls unconscious, Johnny and Kanda take him to a hotel to rest, Johnny staying by his side and urging him to fight. In Allen's mind, he is being shown some of Nea's memories, and he starts talking aloud in his sleep the lines that Nea said to Mana. While Allen is still watching Nea as young child with Mana, the Nea takes over Allen's body and incapacitates Johnny. As Nea is surprised by Allen's appearance he asks Timcampy about Allen. Just then, Kanda enters and places his sword at Allen's throat demanding to know if he's the 14th. However, Nea let Allen control his body after having a talk with Tim privately. Allen is horrified by Kanda's blade at his throat, stating he's Allen, but Kanda does not believe him and points to the injured Johnny before saving him. Allen, realizing the 14th hurt Johnny, is in disbelief that he hurt his friend. Johnny (even knowing Allen nearly killed him) tries to get close to him, but Allen tells him to stay away while activating his Crown Clown. He declares he is going to fight his own way as an exorcist and begins crying and says how sorry he is to Johnny, yet he still does not want to give up despite the situation. However, he is shocked by Johnny's determination to help him as his friend and, in a moment of surprise, Allen starts blushing uncontrollably. Kanda and Johnny use this moment to tie him up.

Allen is then forced into "Johnny's Speedy Repair Service." He's handcuffed to Johnny so he can't run away again. While helping the business, he thinks he should leave since the 14th harmed Johnny so easily. He also realizes how lonely he was and that the Noah and the Order are not the only ones after him when his Innocence activates alerting him to Apocryphos' presence. He runs out of the shop he and Johnny were working on a repair, trying to put as much distance between himself and Apocryphos when he hears someone call "14th..." and turns to find the Earl before him. Seeing the Earl before him, the Earl then blows a balloon up and Allen questions his reasons for appearing, believing the Earl wanted him to lure out Apocryphos. Johnny's gadget then reacts and zaps him, causing Allen to try and bite it off annoyed how the Black Order's gadgets still haunt him. The Earl then tries to crush him, but Allen dodges and begins to question the Earl's odd behavior. He tries to activate his Crown Clown but Allen gets no response and notes the Earl has lost it and wonders if it has something to do with the 14th. As Johnny arrives, the Earl smashes Allen into a wall and Johnny saves him from getting crushed stating he'll save him despite Allen's pleas for him to leave him. As the Earl throws Johnny away, Allen and the Earl seemingly lock minds as Allen sees flashbacks of Road protecting Mana from what appears to be an angry Nea and later Mana in a field seeing the Earl kill their mother calling him "Mana D. Campbell" and he brought upon this tragedy. While questioning what he saw, the Earl mutters Mana's name over and over and states Mana is the cause of everything. Soon afterwards, Nea awakens in Allen again and takes the complete control over his body, acting on his own will. At the same time, Allen finds himself in the middle of the wheat field, which he recognises as Nea's memories. While wondering about his and Johnny's current situation and fearing he's being absorbed by these memories, Allen meets with the image of Cross, who tells him that it's his final destination. Cross explains that Allen will disappear like the soul trapped in an akuma, these words shock Allen. Allen insists that he wants to know more about Nea, if it could at least give him a chance to try and change something. Cross asks him if there is anything to change in the first place, instead telling Allen to cease his resistance and that it's the best choice to accept the fact that he's going to disappear. However, Cross also says that he never wished for Allen's destruction. He is, after all, Allen's master, and offers to stay with Allen till his end if he was scared. He says that option for Allen to be free from all his sufferings and rest in peace was still open. Allen is ready to agree, yet he remembers his friends and the path he swore to follow, after which he resolves to continue walking until the very end of the war. Astonished, Cross tells him to go alone and suggests that Allen must open his eyes and find the Campbell mansion and the woman, Katerina if he wants to find out the truth about the war, although he admits he'd rather have Allen disappear. When Cross vanishes, Allen suddenly realizes it probably wasn't an illusion. Allen thinks that he will learn the truth about the 14th and will come to understand him. Since his goal was defined, all he has to do is to move forward. However, he wonders how he's going to escape Nea's subconsciousness he's currently trapped into. Suddenly, he hears Johnny's voice which prompts him to fight. Allen sees the image of Johnny who declares he'll become his beacon, and then the scene of him staying on Allen's side when he was unconscious the night before. Allen is shocked to learn that Johnny was calling out for him, despite him hurting Johnny earlier. Johnny assures him that the bonds between people are strong and no matter where they are or how far apart, they remain connected. Allen, encouraged by the memories of his friends and the Black Order, screams out for Nea to give his body back. In the real world, when Nea loses the control over Allen's body, it begins to fall out from a rooftop, and Johnny jumps after him. Eventually, Allen regains his consciousness and activates his Crown Clown in order to catch Johnny and safely land on the ground. He smells Johnny's scent and recognizes the Science section's smell. Allen looks around and realizes with great relief that he came back to the real world. Allen and Johnny hug each other and cry of joy. Allen states that the Science Division really overdoes it, despite his earlier words to Johnny to stay away from him, much to the latter's joy. Allen thinks to himself that he was running away from Johnny and the others earlier. They are interrupted by Tyki Mikk who grabs Allen's hand to check that he is not Nea anymore. Allen freaked out, pins Tyki on the ground. Johnny and Allen quickly chat about what happened. Johnny learns that Allen had no clue what happened while Nea was in control and Allen learn that Johnny was unconscious. Tyki Mikk suddenly decides to bring Allen home with him but he is fortunately stopped by a creation of Froi Tiedoll which creates a huge explosion. Allen and Johnny are blown away and Allen has some trouble to get up as he out of synchronization with his body. Allen thinks that he must call Timcanpy so they can leave the area but something forms from the ground beneath them and in a few seconds they find themselves trapped in a coach which drives them far from the area. Johnny understands that this is General Froi Tiedoll's work and that the Black Order found them. Johnny panicks as he notes "this is bad". Allen tries to open the curtains but to no avail. He thinks that he doesn't have the time to be taken back by the Order and he needs to go to the that Residence.The carriage stops and the curtains open to show Yu Kanda and Tiedoll. Allen first only sees Kanda (who is the one who opened the curtains). He and Johnny soon realize the presence of the general and Allen immediately invokes crown clown, ready to fight. He assumes that after all, Johnny and Kanda really were here on the Order's behalf to capture him. He cuts open that he will kick Tiedoll's ass and escape this coach prison. Kanda cuts him and explains the situation: the whole area is surrounded by the order. Allen does not intend to listen to him and brandishes his sword instead. The blade is parried by Kanda. Allen protests that he is alright on his own and can get by himself with Timcanpy. He feels cramped as Kanda pushes him against the carriage. Suddenly Allen feels the presence of Nea within him and falls on his knees. He shouts to Johnny who was about to help that he is fine. Allen proclaims that if they're not going to take him they should just leave him. In his current condition he can't protect a simple human like Johnny and Kanda with his reducing lifespan, calling them "fragile beings". Seing the reactions of the two, Allen realizes what he's done and avoids their glance. Kanda decides to knock Allen out and grabs him by the collar only to be stopped by Johnny. General Froi Tiedoll speaks in and after giving a piece of advice to Kanda, he gets a jar out of his bad. Allen and Johnny wonder if this is salt. Kanda then questions Allen about the thing who is after him, the human shaped innocence. He reveals that Timcanpy attempted to protect Allen and got destroyed by a shard of wood for it. Allen is utterly disturbed by Kanda's words, so much that he can't think clearly and his heartbeat fastens. Kanda finally points at the jar: the powder is what is left of Timcanpy. Allen recalls his encounter with the golems and all the moments they shared. He gets his hand closer to the jar as his lips quiver. Allen stays silent for a while as the coach runs outside town and through the countryside. He thinks that he can't let other exorcists know about Apocryphos lest they might become fallen ones. He then contemplates how taking Timcanpy with him had his golem killed and regrets this choice. The memory of Timcanpy suddenly reminds him Mana's answer when Allen (Red then) had asked why he wasn't crying over his dog's death: "perhaps my tears have all dried up" and "if I grieve the earl will come for me". With that he finally understands Mana's words as he is now in the same situation as him. Allen suddenly raises his head and opens an ark gate below him, he turns to Kanda and apologizes, saying he will take care of the human-shaped innocence by himself. Kanda rushes at him and they both vanish into the Ark. They appear in the sky of Edinstown with Kanda holding Allen's ankle. When they land, Allen is startled at Kanda following him. Before he can recriminate, a shock is sent by Allen's handcuff, leaving him in a daze. Kanda grabs Allen by the collar and asks where Allen sent them. Allen claims that he doesn't know as the only thought he had when teleporting was to get away from them. Kanda threatens him out of running away with mugen unsheathed. Allen protests that Kanda pretends to help him but is instead cornering him. At this instant Kands cuts off Allen's tie, the boy is astounded and notes that he didn't even see Kanda draw, he ponders that maybe Kanda will kill him. Kanda explains what Johnny sacrificed to help Allen and the latter faintly attempts to silence him. Kanda attacks again but Allen backflips out of the way, Kanda's blade follows swiftly and Allen blocks it wit his left arm. Allen replies that he knows that too well. He goes on as Kanda keeps pressing the blade into the flesh: He knows but he just can't say it. The human-shaped innocence Apocryphos has killed Cross, Tim and Link, it destroys everything. It's a monster and if the people in the Order were to learn about it they would lose faith in innocence and in their cause and the Order would be doomed. As Kanda withdraw the saber, Allen declares that he is the target of Apocryphos but as it destroyed what he held dear he can't just let it get him. Allen puzzles at why he spilled out all his beans, maybe because having someone by his side gives him hope and strength to go on. Allen falls down on the ground and puts his left arm on his eyes. Tears flow as Allen realizes that Tim really his gone. He cries his eyes out after talking it all out. Allen suddenly sneezes which makes him realize hos cold the place is. Kanda demands that he takes them back to Tiedoll and Johnny. Allen answers that he can't because he was shut inside the coach with the windows closed so he doesn't know where it is. Allen looks around him and notices a symbol on a tree. He runs to it and recognizes "Mana's letters". He dusts nearby the tree and and finds the lump of earth. He informs Kanda that they are in Edinstown, UK, the place he met Mana and "Allen". Allen and Kanda move ou of downtown, beneath a folly in a nearby garden. Kanda explains his plan to send his golem to general Tiedoll and wait for their return. Allen comments that this won't work if the general turned his golem off but Kanda dismisses the idea. They watch silently the golem fly away. Allen's belly grumbles prompting Allen to say that they'll just have to find food while waiting.Kanda watches Allen with a grin and notes that the boy's done running. Allen admits to it and adds that since he told him about Apocryphos he might as well drag him in. Kanda asks about Allen's past, the latter is very surprised and tries to act it out but Kanda asks again, seriously. After some reflexion, Allen mentions how he looked into Kanda past in the North American Branch. He apologizes for peeking in his secrets. Suddenly Akumas appear around them, Allen jumps in with his innocence activated and tells Kanda that he will tell him everything when this is over.

Allen proceeds to tell Kanda his story, starting from when he was an orphan in the Garvey Circus and met Mana.
