No matter what happens, I will always love this beautiful world.
— Mana to Red

Mana Walker (マナ・ウォーカー, Mana Wōkā) born Mana D. Campbell (マナ=D=キャンベル, Mana D Kyanberu) was the adoptive father of Allen Walker and the older brother of Nea D. Campbell. After Nea's death, he became a travelling clown, and worked alongside his dog, Allen.


Typically, Mana is seen under the guise of a classic whiteface clown; he wears white makeup which fully covers his face, ears and neck, accompanied by red and orange makeup to accent his eyes and mouth. He wears an oversized costume typical of whiteface clowns, complete with a ruffled collar.

He has slicked back, dark hair, and is usually seen in a travel-worn suit, top hat and frock coat, the latter of which has cufflinks that bear his coat of arms; an ornate shield with a coronet supported on both sides by banners. It has been noted by Red that he has golden eyes.[1][2]

When Mana was a young man, he had wavy hair which is tied back into a ponytail.


Mana was a comical though somewhat emotionally distant person, often resorting to humour when he could not express himself properly (such as when he "hanged" himself from a tree at Allen the dog's passing and told Allen—then known as "Red"—he was "so sad he could die", doing so because he could not shed tears).[3] Furthermore—according to Cross—after Nea's death, Mana's sanity started slipping.[4] However, when Allen began travelling with him, Mana became a more paternal person, teaching Allen many things and coming to love him.

Despite this, after finding out he is the host for Nea's consciousness, Allen could not help but question whether it was him or Nea that Mana loved.[5]


Mana as a child.

The Earl of Millennium once vanished, leaving only two new-borns where he stood. The two babies were found and adopted into the Campbell Family, and were given the names Mana and Nea. They were raised by Katerina Eve Campbell in the Campbell Residence.[6] At some point Mana became very ill, leaving the Campbell residence fearing that he would never make it to adulthood.[7] Katerina looked after him day and night, seven days a week. He eventually recovered to the delighted shock of Nea.[8]

Mana stayed by his younger brother's side even after Nea became a Noah, and when Nea betrayed the Noah Family and his coup failed, Mana went on the run with Nea, fighting the Earl alongside his brother until the Earl succeeded in killing Nea.[9] After Nea's death, Mana's sanity began slipping, and he became a travelling clown, going from circus to circus as a contract worker while fleeing the Earl.

As a clown, he owned a dog named Allen, and at some point he joined a circus in where he met a clown named Cosimov and a boy named Red. He soon became the star performer, which caused Cosimov to become so jealous that he ended up beating Allen the dog to death. As he buried Allen, the young boy named "Red" approached Mana and attended the small burial with him, their conversation revealing that Mana would be leaving the next day, on Christmas. On top of this, it is also revealed Red was the victim of Cosimov's jealousy-fueled beatings.[10] When Red asked Mana why he didn't cry over Allen's death, Mana explains that his tears had long since dried up, and Red then asked for the dog's name, explaining that Allen had licked his hand and had been friendly to him. When Red started crying, Mana realised that Red had considered Allen a friend.[11]

Later, the Earl and an army of Akuma attacked the circus, killing everyone but Mana and Allen, who managed to escape and start to travel together.

Mana insisted the Red take the name "Allen," and as they travelled Mana taught Allen several things. After seeing Mana drawing a symbol wherever they went Allen asked about it and Mana explained that it's a sort of lucky charm and that it means "I'm here"[12]. Mana then decided to teach Allen how to perform and how to read the symbols which would be later revealed to be the Score for controlling Noah's Ark. Though Allen, not knowing this, would only think of the symbols as a special language for only himself and Mana.[13]

Three years after meeting Allen, Mana died. Allen, in his despair, brought Mana back as an Akuma, and after gouging Allen's eye and cursing him with the ability to see the souls of Akuma, Mana told Allen he loved him before Allen's newly awakened Anti-Akuma Weapon slew him.[14]


Introduction Arc

Mana appears briefly in a flashback when the Earl of Millennium calls Allen out on killing his "father," revealing to Jan, who Allen is protecting, that Allen had done the same thing Jan's friend, Leo, had done to his mother. In the flashback, the Earl approaches Allen as he sits at Mana's grave, and when the Earl brings Mana back in an Akuma skeleton for Allen, Mana becomes enraged and curses Allen, cutting his eye.[15] The stress of this attack causes Allen's Anti-Akuma Weapon to awaken for the first time, and as the Innocence lashes out at Mana against Allen's wishes. Mana tells Allen he loves him and begs him to kill him.[16]

The Vampire of the Old Castle Arc

When the Akuma Eliade injures and knocks him out, Allen is approached by the apparition of Mana. Allen tells Mana that, even if his cursed eye, which had been damaged during a confrontation with Road Kamelot, hadn't healed and he hadn't regained the ability to differentiate between Akuma and humans, he would have gone on to fight alongside his friends, wanting to share their fate.[17]

As he fades away, Mana tells Allen that he should "go deeper into the world of black and white," and when Allen awakens, his cursed eye has evolved.[18]

Noah's Ark Arc

As Allen recovers from his recent battles in Edo and on board Noah's Ark, he reflects on his ability to control the Ark. He cries as he realises that the symbols he uses to control the Ark are the same symbols of the secret code he and Mana had "made up," causing Allen to not only doubt if the path he is walking is his own, but Mana too.[19]

Invasion of the Black Order Arc

When Howard Link begins questioning Allen about his knowledge of the symbols that control the Ark, Allen keeps the fact that Mana taught them to himself, though he is left, again, to wonder who Mana was.[20]

Destruction of the Black Order Arc

After Lulu Bell's attack on the Black Order's European Branch is thwarted, Cross is sent back to Central before he and Allen can talk. When questioned by Komui Lee about the score, Allen reveals that he has no idea how the Score imprinted itself on his memory. He becomes distraught, and at that moment only wishes to speak with Cross; if Cross could tell him that it was okay to trust Mana, he would be fine with everything else.[21]

Disappearance of Cross Marian Arc

When Cross reveals that Mana and the 14th Noah (Nea, though he is yet unnamed) were brothers, and that the 14th's memories are taking over Allen's body, Allen asks if Mana had even loved him, to which Cross can only say that Mana had started acting strangely after the 14th's death.[22]

Artificial Exorcists Arc

While recovering from grievous wounds he accidentally inflicted upon himself, Allen has a dream about Mana. In the dream, Mana approaches Allen and invites him to come along with him, and as Allen regresses to a child-like state, Mana slowly stops calling Allen "Allen" and calls him something else, this new name obscured.[23] Though Allen goes with Mana happily, he still silently begs Mana not to call him by this other name.[24]

Searching for A.W. Arc

After the reveal in Night 219, Nea keeps calling the Earl "Mana". which causes a confused Earl to ask why he calls him that. Disturbed, the Earl keeps repeating that he is "not Mana", and he finally snaps; while attacking Nea, he states that he knows where Mana D. Campbell is: According to him, Mana is in "a place from where he can't return". In Edinstown, Allen finds a symbol that had been written by Mana when they were in the city. As Allen recalls, the symbol means "I'm here". [12]


  • Mana's mature face is never clearly shown until chapter 232. Prior to this, we only see him partly from behind and see his whole face only when he was young.
  • Mana declared himself as 17 years old in Reverse Volume 3. This is how old he was when Nea tried to usurp the Earl of Millennium.
