Shu learns confusing things about Funeral Parlor’s agenda in GHQ custody, and it doesn’t help that Gai refuses to answer any questions--or that he breaks into GHQ to rescue not Shu, but a known murderer. Without any straight answers, who can Shu trust?

Gai's come up with a new mission, but before Shu can officially join the team, he has to show that he measures up by winning a mock battle against Ayase's Endlave. Time for basic training! But can Shu concentrate on combat after Inori turns him down?

A change in circumstances forces Funeral Parlor to carry out their attack against the Leucocyte with drastically reduced manpower, and that's BEFORE Shu pulls out of the mission. Still, learning a few new things about Gai just might change his mind.

Shu's having horrible flashbacks, both to images of his battle with Jun and to other, even more upsetting images that soon have him quitting Funeral Parlor and alienating the people in his life.

Gai is back, but he doesn't seem like the man he was before. The Funeral Parlor regulars are in shock, Shu and Inori are in hiding, and Arisa's not having much luck winning friends on any side of this fight.

As Funeral Parlor and the U.N. troops converge on Ward 24--for drastically different reasons--Inori hovers on the edge of becoming Mana. Meanwhile, the mysterious boy who first took her finally reveals his plans for Shu and Gai.

The Fourth Apocalypse is upon us.
