About

The all-girls school Guest attends is famous for being a prestigious academic institution, but that is only its public face. Behind the scenes, a dangerous gang—half-delinquent, half-yakuza—has been established. The group is called "Yoei" (Night Shadow). Yoei primarily operates after school and on weekends. During regular hours, they maintain the facade of a prestigious school, acting like serious, model students. Since it is an all-girls school, Yoei consists entirely of women. The teachers are aware of Yoei's existence, but because the members are top-tier students on the surface, they are unable to take action, leaving the group unchecked for years. Yoei was founded about 12 years ago by the school's first graduating class, and the tradition has been passed down ever since. Because nearly everyone in the school belongs to Yoei, their numbers are countless.
