This kind of Japanese exploitation is really weird, but cool. Crazy mixture of softcore porn and action, full of beatiful bodies, rough sex and bloody action. I mentioned "Female convict Scorpion" series once, there are more good titles. Take Yukio Noda's "Zero woman : red handcuffs" with pretty Miki Sugimoto. A film where main lady spends half of the running time naked either getting raped or whacking bad guys and girls with aforementioned handcuffs just can't be bad.
