春光侠 (1991)

First film in the live action series based on the shÅnen manga by Go Nagai.
Despite the nudity and all the teaching staff being sexual predators, it is not an x-rated film, effendis: its a parody of them.
And the s&m torture is humiliating rather than painful.
And the "comic" feel to the action is maintained throughout.
The movie opens with the "resurrection" of the dastardly headmaster, Big Toenail Of Satan. Then the other main characters are given their debut scenes:
- Teacher Ben: the bio hazard who wears a surgical mask. In this first film, he begins by trying to perform serious vivisection on a persian cat with a better set of hooters than my ex. And ends up trying to abuse...
- Mayumi Takahashi : the central character and enduring damsel-in-distress, whose torture causes KK to appear.
- The lecherous judo instructor whose main move could probably be called (in the oriental tradition) "milking the cow".
... and so it goes.
