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.
