Bad at study and bad at sports with no desire to get better, school was a meaningless drudge for the protagonist until one day he gained an ability that redefined school life itself.

He instituted new regulations that made his brutal fantasies into reality. A new school life with nude attendance, where menses are announced and sex can happen anywhere......

The power of hypnosis makes anything possible.
School is bright and fun, at last!
