An uneasy atmosphere grips Star Haven High School. Mysterious incidents targeting girls begin to unfold one after another, and rumors soon spread of things more suited to urban legends. And it is up to Beni Akesuzu as the head of the detective club to get to the bottom of these incidents. But even she has a secret: she’s a secret agent for Bancho, a secret organisation specialising in dealing with the supernatural, and they know the truth. That real monsters lurk in the shadows, plotting to brainwash everyone in the school. So far, Beni has narrowed her list of suspects, including both teachers and students. Now, it’s up to her and her friend, a fellow detective club member Nadeshiko to track down the culprits and solve the puzzle in a race to save the school and its students before it’s too late!
