About

Kamiyama High School. Official name: Kamiyama Senior High School. Classes generally run from the first to the sixth period. However, there is a hidden side: the teachers are all serious criminals. They aren't exactly here to atone for their crimes, though. It's simply a school built by felons so they can do whatever they please. Every student who graduates from here leaves with something inside them broken. In fact, some students reportedly choose to stay behind because they don't want to graduate. The principal and the board chairman do nothing but follow the teachers' whims.
