It all began quite suddenly. Akihito, who appears human but is actually half yomu with the power to quickly heal himself, sees a freshman girl who appears ready to jump from the school rooftop.

Akihito, now a high school senior, starts to avoid Mirai thinking it’s for the better. Not aware of Akihito’s feelings, Mirai tries to get closer to Akihito. Then, someone who knows of Mirai appears in front of the two. With Akihito’s troubles in vain, Mirai once again sets forth on a battle that forces her to look within.
