Tousuke Rokudou is a loser, and everyone knows it. He gets picked on at school, gets snide looks from passersby, and can only muster up the courage to complain in secret with his equally hapless friends. Looking to turn his life around, he desperately uses an ancestral artifact passed down in his family for generations: a scroll that is capable of subduing all demons. However, in the modern age, it has a different effect: it makes all bad girls fall in love with him. Things go ballistic when he meets the delinquent beast-on-a-girl's-body Ranna Himawari, who hopelessly falls deep for him. See Rokudou traverse through a school life filled with delinquents, turf wars, backstabbing, and as the song goes, "Everybody Was Kung Fu Fighting"!
