Majo no Iru Kyoushitsu

Mari arrives at her new school and witnesses a boy fall from the roof, raising questions about whether it was an accident or intentional. Strange rumors about a witch's curse begin to surface, followed by unsettling events. Convinced that "if I don't kill her, I'll be killed," Mari becomes determined to uncover the truth. The collection also includes four additional stories: "Moebius no Yoru," "Mangetsu ga Miteita," "Kami no Te," and "Kurayami." Each explores unusual and eerie occurrences in ordinary settings, as Oohashi delves into the hidden horror within the mundane.
