It has been a long time since I last watched this, but from what I remember it seems like one of the rare Cat III films with an entertaining plot.

Anyways, this is a bit scratchy. There is a demon who requires virgins to deflower in order to remain alive. However, the village where his source of virgins came from has run out, so they send a woman to pretend. When the demon finds that he has been conned, he gets angry. There's also an enigmatic swordsman with a scarred face who pops in and out intermittently. And that's about all I remember :)
