Ura Tokyo no Osoroshi Dokoro

Beneath the surface of Tokyo exists a hidden city known as Ura-Tokyo, where an academy trains students to become exorcists. Soma Kuroniwa enters a restricted area in the Madara Shirazunomori Forest and becomes cursed with a dangerous spirit. To conceal his condition, he joins the academy and undergoes intense training, as only a small percentage of students complete the program. When a strong spirit approaches, the dormant power within him begins to stir. The story follows this academy setting, focusing on action and the challenges faced by its students in a dark, detailed environment.
