Plot

Three schoolgirls are infatuated with a yakuza, Katsuta, of the Izu Clan. They meet another yakuza, "Diamond" Fuyu, of the rival Yoshida clan. As he gets a tattoo, two of the girls become squeamish and run off but Hanako, the best friend of the daughter of Sota Izu, boss of the Izu clan, stays to watch. She is intrigued with the yakuza world. Fuyu takes her to an illegal gambling den where Tetsu, a dealer, takes a liking to her. The police raid the den and Hanako is arrested but let off with a warning. Later, Tetsu runs into Hanako on the street and convinces her to help him pull a variant of the badger game, a scam in which, with the promise of sex, she is to lure a man to a hotel room where Tetsu will extort money from him by threat of blackmail. The scam fails when the man chases Testu off and Hanako is left stranded with the man.
