A popular and serious new teacher, 'Rin'. One day, she calls out a student in her class, 'Suzuki', to give him a warning. 'Suzuki' had been taking secret photos of female students during class and causing trouble with violence inside the classroom. No matter how much Rin warned him, 'Suzuki' showed no reaction and stopped coming to school the very next day. However, later on, she received a message saying, 'If you come to the place I specify, I will listen to what you have to say.' Though Rin found it strange, her superior, the vice-principal, urged her to 'accommodate the student's request as much as possible,' so she went to the specified location... only to find that it was a hellish place for 'Rin'...
