Otonokizaka High School stands on the border of three cities: Akihabara—a pop culture mecca that's evolving by the minute; Kanda—a conservative, cultured city where history and tradition reign supreme; and Jinbo—a quiet area reserved for a more mature, sophisticated population. Amidst this culture clash, the school now faces closure due to the enrollment of fewer and fewer students.

dark fantasy follows a high school sophomore named Akihito Kanbara. Although the boy appears human, he is half youmu and invulnerable to wounds because he can heal quickly.
