Delinquent Girl Boss (1971)
After a life in reform school, Rika (Reiko Oshida) tries her hand at becoming a decent, upstanding citizen. But try as she might, she just can't get the hang of the straight life. She finds herself back in the big city where the hippie revolution has taken hold and psychedelics are the drugs of choice. Back on the streets, she meets up with her old reform schoolmates and becomes embroiled in an underworld full of gangsters and shifty kidnappers who have a taste for money and women. Now, Rika must rely on her two greatest assets—her beauty and her butt–kicking skills—to help her friends take brutal revenge!

Abused to no end at the hands of some rough customers, the girls find themselves the currency in a brutal transaction.
