My name is Jotaro Shimohei.There is a reason why I came to work at this time, which was not even the beginning of the academic year. That's a huge blessing for the teacher. Mahiru Kuji, who had been cheating, was rehabilitated. Mizuki Tono, who didn't attend classes because she was an outstanding talent, started on the right path. However, there are still many problems. Minami Shiwa, Mizuki's younger sister who is a habitual napper, and Hinako Kuji, who was ``letting'' her younger sister Mahiru cheat. And a new spark was about to smolder in her mind. --Rehabilitate students who violate school discipline... Now, a storm of moral and moral cleansing is upon us. rn
