Daimon High School's student council president Isozaki asks martial arts expert and fellow classmate Ryoko to collaborate on an effort to sweep the streets clean of troublemaking scum. But his hidden agenda is clear: he wants to expand the K-Fight program beyond the school's campus, and does so by pitting Ryoko and four other women warriors against Shizuma and his band of brawny brawlers. Surprisingly, Ryoko not only accepts the challenge but agrees to head the group of lady fighters as well, hoping the experience helps her attain her ultimate goal of becoming a great woman. The battle of the sexes is, literally, at hand.
