After School Nightmare vol 05

Ichijou Mashiro seems to have it all - he's popular, good looking and attends a prestigious prep school. But Mashiro has a secret - he's neither male nor female. So far, Mashiro's been able to live his life as a boy, but all this changes when he's informed of a new class he must take in order to graduate. Mashiro is told to find the Key to graduate, and the only way to do so is to enter a nightmarish world with several other anonymous students in a twisted group therapy session. These terrifying after school classes will challenge Mashiro's notions of friend and foe as his body and soul are put at the mercy of the worst kind of enemies: his classmates!
