Stream Stray Cat Rock: Delinquent Girl Boss (1970) : Free. The first part of the Nora-neko rokku ("Alley Cat Rock") series was originally Nikkatsu Studios' answer to the rivaling Toei Studios' Delinquent Boss series, but spawned four sequels thanks to its popularity. Onna banchô, the first movie in the series, takes place in Shinjuku, Tokyo where rivaling youth gangs are constantly trying to one-up each other in toughness. An all-girl gang led by Mei (Meiko Kaji) gets involved in dangerous circles when Mei's boyfriend Michio (Kôji Wada), wants to join a powerful yakuza organization called Seiyu but inadvertently loses the gangsters' money in a fixed boxing match. Of course, Mei's gang is not going to leave him to the gangsters, especially when helped by an enigmatic and independent female biker called Ako (Akiko Wada).
