Many years ago, Cross Marian brought a younger Allen to a caretaker when he fell into a trauma after attempting to revive his guardian Mana and turning Mana into an Akuma. As Cross took care of Allen, Allen recovers but starts behaving like Mana. In the present day, after abandoning the Order, Allen returns to his caretaker. Sheril continues torturing Lavi to know the truth behind Road's past and her relationship with Nea. At the same time, Kanda returns to the Order to make peace with the dying Zu, the scientist who launched the Second Exorcist Project. While synchronizing with his Innocence, it turns into a crystallized form. Later, Kanda reveals to Marie and Lenalee that he only returned for Allen as a self-redemption for awakening the 14th. Elsewhere, Allen starts fighting Akuma who react to his transformation into Nea. When Allen starts to transform again, he remembers Mana's and Cross's words of encouragement, which allows him to regain his body.

Link tries to stop the Cardinal when he attacks Allen, but is easily subdued. Allen attacks the Cardinal with his Innocence, but discovers that he is a non-human being as well as the person who fatally shot Cross Marian. Tyki, Road and the Third Exorcists arrive under orders from the Earl to save Allen. Tyki reveals the Cardinal is actually Apocryphos, a sentient Innocence existing solely to protect the Heart, which the Noah has been searching for 7000 years. Apocryphos reveals he will merge with Allen to save him from the 14th, and a fierce battle ensues between him and Tyki. Meanwhile, the Exorcists and scientists ask Rouvelier and Komui Lee to free Allen, but to no avail. As Apocryphos overwhelms Allen and the two Noah, Link frees Timcanpy and explodes a hole in the prison wall so that Allen could escape. The Pope revokes Allen's rights as an Exorcist and Komui commands all Exorcists to capture Allen. Lenalee refuses to believe Allen has betrayed them and chases after him.

After the Hekiji barrier placed on the North American Branch is canceled, Allen sees the soul of Alma Karma, who became an Akuma, and learns why Alma has been trying to kill Kanda.

While in Yuu’s memories, Allen sees what the Black Order was doing to Yuu and Alma Karma in the name of the Second Exorcist Plan nine years ago, and how Yuu ended up killing Alma Karma.

Some of the Black Order’s staff are brought into the North American Branch to observe Alma Karma, the parent body of the Third apostles. However, during the meeting, the branch is attacked and comes under the Noah clan’s control.

While Allen, Kanda, and Marie are fighting AKUMA inside Hearst Orphanage, Timothy awakens as a new Innocence Accommodator. Meanwhile, Reever and the others try to enter the building, but they are hindered by an enveloping barrier.

After collecting Innocence, Allen and the other Exorcists are headed to the Black Order's new Headquarters, where Director Lvellie and Allen's Master, Cross Marian, await Allen's arrival.
