This demon embarks on a terrifying quest, targeting any girl who matches Kumiko's description. In this blend of comedy and horror, the students must navigate the thin line between their everyday lives and the dark forces at play, all while relying on their teacher, Nube, to confront the supernatural threat that looms over them.
