 It's Not A Manga!

Yokai, ghosts, and humans living together in harmony? Yushi Inaba was taken in by his uncle’s family after losing his parents in an accident three years ago. Now sixteen and eager to make it on his own, he hopes to move into a dorm upon entering high school. But by a cruel twist of fate, the dorm burns to the ground! After searching high and low, Yushi finally manages to find an apartment at the too-good-to-be-true price of 25,000 yen per month! Sure enough, there’s one condition: the apartment is haunted! Surrounded by a gaggle of colorful tenants, Yushi’s “normal” high school life begins! Waka Miyama delivers an elegant comic based on the popular novel series by Hinowa Kouzuki.
