To keep her village safe, Kazemi, the wife of a fisherman, has entered into a dark secret bargain with a monstrous yõkai spirit that lurks in a nearby cove. They remain prosperous…and in exchange she offers herself to the creature and lets it exact his lustful desires on her.

But the appearance of a wandering Rõnin and Yõkai hunter threatens to expose her secret affair with the creature, forcing Kazemi to go to even greater extremes to not only protect her village but the young girl Izumi as well. Desire and duty clash towards a violent endgame in an erotic tale of monsters and the women who fall prey to their whims.
