Fan Casting Devil's Vendetta

The devil interrupts a Buddhist prayer session. While under a hypnotic trance, one of the priests slices open his chest and pulls out his pulsing heart. The devil devours it, whereupon he transforms into a gorgeous demoness. Heavenly rays suck him/her into the afterlife, where she opts to become a vampire and return to earth. Two rival Taoist schools - one all-female, the other one all-male - decide to join forces to fight the demon. One of the female fighters becomes aware that she's the daughter of the demon and must to loose her virginity to avoid transforming into a vampire herself.
