Welcome to Tokyo: a ravaged world under merciless totalitarian rule. More and more of Shu's old friends are seeing a side of him they never imagined possible... and Shu's about to see a new side of the Voids, too.

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.

Things have gone too far, and as a mother, it's up to Haruka to do something about it. But fortunately or unfortunately, no one in her life seems willing to let her--and she's not the only one who's made a decision.

Ten years ago on Christmas Eve, Mana, Shu, and Gai had a fateful encounter in a church. That’s the story we already know. The story we don’t know: where were their parents?

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.
