When Akihito sees a girl about to jump off the school roof, he surprises even himself as he races up the stairs to rescue her. Much to his surprise, the girl he saved is a Spirit World Warrior. And as a half-youmu, he’s now her prey!

Mirai and Akihito must defeat the Hollow Shadow while dodging around Sakura. The youmu can not only possess people, but also create labyrinths based off their memories. If Mirai hopes to have a future, she will have to face her past!

Mirai goes after a perverted youmu with an eye for human girls. When it sprays Mitsuki with its stink juice, the Literary Club must band together to defeat the powerful--and horrendously stinky--youmu!

In a dream, Mirai informs Akihito of what happened during their battle and why it had to be this way. Then time jumps backwards to six months earlier. At long last, Mirai’s motives and Izumi’s plan are made clear!
