Once every 3,000 years a monstrous being known as the Overfiend enters the human dimension in order to destroy it. According to legend, our world must be overturned to pave the way for a future in which humans peacefully co-exist with a world of Man-Beasts and a world of Monster Demons. People scramble amid the rubble of a dying universe in this film that single-handedly created the erotic grotesque genre of Japanimation.

Amano Jyaku is on a quest to find the savior of the three worlds, a legendary god among gods known as the Chojin. His search takes him to Nagumo, a geeky teenager who spends his time trying to peep into the girls locker room. But Nagumo`s hidden power transforms him into a sex monster with an apocalyptic, planet-destroying destiny even Amano can`t prevent!

This controversial series was one of the primary forces in the launch and growing popularity of the "erotic grotesque" genre of Japanese anime. Fast-paced and with excellent animation, the gritty, often disturbing series features apocalyptic battles, enslavement, sexual depravity, demons and desperate grabs for power by some of the most disturbing characters to hit the screen.
