Ryo is sent out by the people of a village to kill the monster which has been attacking the villagers. It is rumored that this monster is a cat-woman named Bagi. As Ryo waits for the monster to come to its watering hole, he thinks back to how he first met Bagi as a kitten who learned how to write, and later reenters his life on a quest to discover who and what she really is. But now she has gone wild, and as the time of her arrival approaches, he strengthens his resolve to kill her.
