Houkago no Futekikakusha

It is autumn at Shuuka Academy. Third-year Itsuka has a group of friends he trusts: twin childhood friends Asagao and Yuugao, his soccer-club best friend Jun, his partner-in-crime Kousuke, the class president Kanade, and their homeroom teacher Shiori. Nothing in his life is exceptional—which is fine with him. On the way home from a choral competition, the group encounters strangers who change everything. What follows strips away the ordinary life Itsuka was living, replaces it with something cold and violent, and forces him to watch the bonds he built be destroyed in his own hands. There is no salvation in this nightmare—only the question of what he will do inside it.
