The main character lurks around a corrupt, misogynistic “high education” high school called the Sparta Academy (スパルタ学園 suparuta gakuen?), where the penalty for any student (usually girls) making the slightest mistake is being sexually humiliated by the perverted teachers running the school, the mastermind being a demonic, jester-like villain named “Toenail of Satan”. Before the teachers take their sexual advances too far, Kekko Kamen breaks in and beats up the bad guy before performing a finishing attack by jumping into the air and landing crotch-first onto the opponent’s face. In the anime, the impact causes him to lose consciousness. Sprawled unconscious on the floor, the villain usually has a smile on his face. In the manga, Kekko Kamen often kills the villains with her crotch attack, or with a hit from her nunchaku.
