Furyô Banchô otebisha

This is the sixth film in the series. There were seventeen Wolves of the City films between 1968 & 1974, in the main aimed at shock-value & "pinku" soft-core with sex, nudity, violence, gunplay, & a lot of mainly pointless foolishness when the biker gang coopts racist or nazi imagery, inventing a non-existent youth culture void of morality...
