When transfer student Sakura Sakuraba arrives in the town of Yuuyamichou, she quickly realizes this is no ordinary place. Behind its quiet facade lies a community bound by strange, time-worn customs, where every local child bears an unusual name and lives under a peculiar curse: none of them may leave the town until they graduate from high school. As Sakura settles into her new life, she finds herself pulled into an ever-deepening nightmare. Supernatural phenomena surround her at every turn—curses that defy explanation, eerie summonings, and betrayals she never saw coming. The more she uncovers about Yuuyamichou and its trapped children, the darker and more dangerous the mystery becomes. Determined to break the curse and set the children free, Sakura joins forces with Uzu Andou, the enigmatic president of the Paranormal Club. Together, the two begin peeling back the town's secrets one baffling phenomenon at a time. Their unsettling and unpredictable "club activities" are about to begin!
