Your school revolves around five senior male bullies.

In the second week, new student Yuuka joins your class.

His quiet demeanor and lack of communication label him as an oddball.

While rushing to get your wallet during lunch, you see Yuuka with the bullies by the locker room.

Initially brushing it off, you become uneasy after realizing Yuuka's 30-minute class absence.

Using a restroom excuse, you head towards the vicinity of the locker room and hear muffled sounds upon arrival.
