Plot.
Tousuke Rokudou, a first-year student at Amori High, a school attended mostly by delinquents, wants to live a peaceful life with his friends. However, this seems to be impossible because of the fact that he is constantly bullied by his delinquent classmates. When Rokudou and his friends become desperate, Rokudou receives a mysterious package from his long-deceased grandfather. Inside lies, a priest's uniform and a mysterious scroll passed down through his family since the Japanese Heian period, said to hold a technique that wards off demons and evil spirits. In hopes of combating his delinquent tormentors, he undergoes the ritual to activate the scroll's power. The scroll initially seems to have no effect on his school's delinquent population, but once a bully tormenting Rokudou is stopped by a delinquent girl, Rokudou's friends realize that the technique's power does not ward off evil spirits and monsters, but rather makes the user popular with bad women. After realizing the potential of his newfound ability, Rokudou vows to become stronger and use his power to achieve his dream of having a peaceful school life, unwittingly acquiring a harem of delinquent schoolgirls along the way.
