Allen sets out to recover Innocence discovered in southern Italy. When a powerful Akuma attacks him, the exorcist comes face to face with something eerily familiar.

Allen continues his battle with an Akuma that has leveled up and gained the power to take on a person's appearance and powers. Meanwhile, Kanda hears from the "Ghost" of Mater the history of the town and the Dolls they made to cheer themselves up.

The adventure in Mater draws to a close as Allen and Kanda discover the truth of who the Doll actually is and then battle the level 2 Akuma for possession of the Innocence.

On his way back to the Black Order headquarters from Mater, Allen meets a boy named Jean. Jean and his friends have organized a patrol to search for Akuma within the town. Allen warns the boy that this is dangerous, but Jean won't listen.

Allen's past is revealed as he confronts the Earl of the millennium, who wants to kill Jean for causing problems with his patrol and calling the Earl "a bad guy".

Allen and Lenalee are sent to investigate a town where the day of October 9th keeps repeating itself. Once there, they meet a woman named Miranda Lotto and thus learn of her significance to the strange phemonenon of the town. The Millennium Earl announces to his family, the Noah Clan, that it is time for them to head out and continue their mission, thus leading one of the Noahs, the young spiky haired girl Road Kamelot, to investigate the Rewinding Town.

The terrible realization that Road Kamelot is a human horrifies Allen, who cannot understand why a human and akuma work together. The talking umbrella Lero chastises Road for going against the Earl's plans, but Road points out this little incident was only to 'spice things up'. To prove herself as different from regular humans, Road stabs herself with Allen's Innocence, only to recover right in front of him quickly. She stabs Allen in the cursed eye, and makes to kill Miranda, but Allen rescues her. Through this Miranda has a realization about herself, which causes a reaction from the Innocence.

Thanks to Miranda's Innocence, Allen and Lenalee temporally recover and fight for survival against Road and her Akuma. Just when things seem to be going well, Road decides to torment Allen by ordering an Akuma to self-destruct, explaining that an Akuma who dies this way will never be saved and their soul will be forever lost. Desperately, Allen tries to exorcise the Akuma before it happens, but Lenalee stops him, and the Akuma explodes. The soul is seen begging for Allen's help, and he takes out his anger on Lenalee, who slaps him before telling him as a friend she had to stop him. Road laughs at the scene before leaving, and Allen tries to stop her, but is unable to bring himself to kill the Noah. Road leaves the dimension promising Allen that they will meet again. The Exorcists, along with Miranda, return to Miranda's home.
