Sister Street Fighter: Hanging By A Thread (1974)

This is the first sequel to Sister Street Fighter. Again, our Chinese heroine must travel to Japan to find a missing person. This time it is the daughter of a friend. The baddie this time is a diamond smuggler who imports his merchandise in the buttocks of beautiful women and then prostitutes them. Fairly perverse stuff that includes a she-male, although I am not sure if he is supposed to be a she or not.

Alternate Titles: Onna Hissatsu Ken: Kiki Ippatsu
