Meanwhile, Hiroomi enters Miroku's barrier and learns that both Miroku and Izumi harbor youmu within their bodies in addition that Izumi isn't the person she claims to be. Izumi then impales Miroku with her spear who seemingly self destructs. Meanwhile, Akihito and Mirai face and overcome their dark memories inside the Beyond the Boundary's core and find themselves in a ferocious battle against an army of youmu. Finally, as the Beyond the Boundary emerges, Akihito beats it into submission and reabsorbs it back into his body.

Sometime later the world returns to normal, with the Beyond the Boundary incident being covered up and Hiroomi taking over the Nase clan. As Akihito laments on a life without Mirai, he suddenly runs toward the school roof when her ring disappears and reunites with her.
