Both Lenalee and Kanda notice brief changes in Allen's persona ever since his last fight. Back in the Order, it is revealed that the Exorcist who saved Timothy is a "Third Exorcist" created by the North American branch using the Akuma egg and the Generals from the Black Order previously destroyed. Meanwhile, the Earl reunites all the Noah to attack the Black Order's branches alongside Akuma. Allen allies with the Third Exorcists, but the latter are attacked by three Noah. Meanwhile, Kanda is taken down by the Noah Wisely who claims he needs the memories of 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.

As Alma Karma finally wakes, the Alma cells that were implanted in the Third Exorcists start to go out of control. When the situation becomes desperate, the Millennium Earl makes Allen an offer.

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.

As Allen and the Noah escape from Apocryphos, Tyki questions Allen about the Order still being his affiliation due to the fact they have began treating him as a Noah. The Exorcists try reaching Allen but they are cornered by several Akuma and the Third Exorcists. Apocryphos' previous attack on Allen causes them to be connected when he activates his Innocence. However, Allen still decides he wants to remain as an Exorcist which causes Tyki to leave. Road disappears shortly after that, leaving Allen with a now smaller Timcampy. As Allen decides to leave the Order compound using his Noah's Ark, he is approached by Lenalee who tells him they will become enemies if he leaves. Nevertheless, Allen says he will remain as an Exorcist after hugging her and leaves.
