Hokenshitsu no Akumu

Four horror stories unfold in a school setting. In the first, a group of boys attempt to prove their bravery by walking alone in a cemetery, but their harmless challenge escalates into a terrifying experience. The second involves a student staying at the school infirmary due to anemia, where ghost stories are common, but she finds the real horror in an overwhelming infestation of mice. The third follows a student who quickly befriends a new transfer student, only to uncover a troubling secret about her pattern of relationships. The final story centers around a mysterious radio broadcast from the school's radio club, which sends an unsettling message to those who hear it.
