Chapter 1

Synopsis
It basically explains the job of an Exorcist. " Exorcists... The ones chosen by the Gods. They exist to hunt down those in darkness." The story is set in an alternate 19th century. It shows an abandoned church used by travelers to sleep in.

Two officers are shown standing outside the church. The lady officer, Moor, decides to enter the church due the complaints of citizens disappearing. The other officer, Charles, is hiding behind a wall and believes that church is cursed. Moor tells him it is not, and the two enter the church. After they head in, Charles screams, saying that something's on his leg. Moor told him that it is just a cat. Just then a horde of bats come flying in. As the bats swoop after Moor and the cat, a deformed arm appears among the bats. The hand takes a swing at the two and pushes them into a room. Charles then realized Moor has gone.

Moor was pushed to a chair. The owner of the hand says that he wouldn't let him get away. He was then surprised he caught a lady, and Moor handcuffed him. Moor realizes it's just a boy but has him handcuffed in the chair. The boy, Allen Walker (the protagonist), explained that he was just catching the cat since it swallowed his valuable thing, which was given by his master. Moor asked him where his master was to which Allen replied, "He's missing somewhere in India". She tells him to stay put, while she rounds up his companions. Then, a loud scream was heard. Moor went downstairs to have a look.

She discovers Charles; he is tied and hanging from a support beam. A black star pops up on his left cheek. Soon, his entire face is covered with black stars, then his whole body turns dark, and finally disintegrates into light chunks. Moor, in disbelief, realizes the rumors regarding the church were true. She is enveloped by smoke and finds that she can't breathe. Suddenly, a hand covers her lower face with a cloth. The hand belongs to Allen, who tells her that the gas from the corpse is poisonous, and that Charles was killed by an Akuma. Moor wonders what Allen meant by Akuma, which means Devil, and then loses consciousness.

Moor woke up in the police station and a man ran up to her and took her into the detective's office. She told the detective Charles was killed. The Detective said that he is interrogating the suspect now. Moor was surprised to see that it's Allen. The Detective said that Allen was the culprit. Allen replied that he wasn't and all he did was bring the police officer there. The Detective saw Allen's hand and said that his hand is red, which must be blood. The Detective was shocked to see a cross burned into his hand. Moor then stated that Allen did not do anything. The man, from just now, told the Detective that a large bullet was found, however, they haven't found any weapons at the scene. The Detective then scolded Moor for fainting. Allen interrupted, stating that he knew the culprit. He also said that it's name is Akuma and he seen lots of them before. The Akuma won't stop killing and that the cross on his hand is an anti-Akuma weapon. He asks them if they knew what are Exorcist, and then tells them that they are an anti-Akuma group comprised of holy priests.

There were a group of people grouped outside the church, saying an officer died there that the church really was possessed. Then, a fat man carrying an umbrella with a pumpkin on top, walks by. Another man said that an incident happened two years ago. The scene was brought to an unnamed man with the fat man behind him. The man, which is the Millennium Earl, called the man his precious Akuma and told him to kill more.

Moor had arrived home and went into the room. The man, her brother Mark, said that she is early today. Moor noticed that he had not eaten again. Mark said that his stomach is full but he will want to eat soon. Moor told him not to give up and that their (or at least her) sister in heaven is wishing for that as well.

Then, there was a loud noise. In another room Moor stops Allen from going back to the church. They both have a flashback, and the scene is brought back to the station. The Detective said Allen could go but Moor ha to watch him. Allen, staring at the church from a window, wondered if the detectives were alright. Moor asks Allen if he really thinks the culprit is an Akuma. She said that an "Akuma" is only an imaginary creature created by ancestors who feared disease and pain. She said that she doesn't believe in curses or Akuma. Allen explains that the Akuma she spoke of isn't the same Akuma Allen referred to. He told her that Akuma is the name of a weapon created by the devil that targets humans. He also said that they normally take the form of humans. Just then, Mark entered the room and began moaning. Allen's eye activates and realizes that Mark is an Akuma. Mark started to transform and turns into the Akuma. Moor was shocked.

There is an explosion and Allen and Moor crash into the church. Moor saw Allen holding on to an object. Allen explains it's a bullet with the Akuma blood. It contains a poisonous virus and if you get hit, the virus infects you and you shatter. The cat had been hit and shatters into pieces. Allen told Moor that the Akuma wasn't Mark, but an Akuma that killed him and took over his corpse. The Akuma arrived at the church. Just then, the Detective and other officers came and saw the Akuma. He ordered his crew to fire at the Akuma. Allen tells them that it won't work and to run away. The Akuma fires back and they are killed. Moor starts shouting at it.

Allen tells her it won't work. He tells her how the Akuma have a soul implanted in it, which is controlled by the creator. Looking at the Akuma with his left eye, Allen says that this soul is a girl, probably one who had a bond with Mark. Moor has a flashback. It was after her sister Claire and Mark got married that she and Moor had a fight about Moor wanting to be a police officer. Claire is in the church crying when Mark comes, with Moor hiding behind him. Mark tells Claire that they should have faith in God. Just as Claire agrees, a giant crucifix falls on her, killing Claire.

Mark is then shown meeting the Earl, who tells him he could bring back Claire, all marc has to do is call to her. He does and then the Earl has her kill him and take his corpse.

Allen then calls upon his cross to destroy the Akuma. It does and Claire's soul was freed. Allen then reassures Moor that Mark and Claire were together in heaven.
