Chika has been comatose ever since the 828 Incident twelve years ago, and her friend Ryo has faithfully taken care of her all that time. But with the Death Spreader on the move again, will it be too late even if she does wake up?

Higaki reveals to Lall and Kyo some game-changer secrets about the KamiErabi and the very nature of the world. A race against time then begins as both the parallel world they're inside and the world from which they came begin to collapse.
