Kyoka, a serious female teacher popular among students, has been struggling as a grade leader since her youth. One day, she called in 'Saji,' a problem student from her class, to give him a warning. The next day, Saji stopped coming to school. When she called him, he only said, 'Come to the place I'll tell you, and I'll talk.' Despite feeling puzzled, Kyoka went to the designated location. What awaited her was... a hellish place beyond imagination.＃養老P
