Agent Sirius

Mysterious incidents targeting girls begin to unfold at Star Haven High School, and rumors of something beyond urban legend soon spread. Beni Akesuzu, head of the detective club, is also a secret agent for Bancho — a secret organisation that deals with the supernatural — and they know the truth: real monsters lurk in the shadows, plotting to brainwash everyone in the school. With her friend and fellow detective club member Nadeshiko, Beni must track down the culprits and solve the puzzle in a race to save the school before it is too late.
