Since ancient times there has been a race of flesh eating monsters called Shokujinki (食人鬼?, lit. "Man-Eating Ogres"). They can assume human form or otherwise live in the shadows while feeding on humans. The Kifūken (鬼封剣?, lit. "Ogre-Sealing Sword") martial arts style school was created to hunt down those creatures and its teachings have been passed down through the generations to the Momota family. The story revolves around the forbidden romance between Toshihiko, the latest heir of the Kifūken school and Yuka, a young woman who is also a Shokujinki.
Toshihiko Momota (桃田 俊彦 Momota Toshihiko?) A skilled swordsman and the chosen heir of the Kifūken dojo. In a move unfitting of his disciplined character he relinquishes his responsibility by running away with Yuka, a woman he knows to be a Shokujinki.
