Wolfull Moon

A girl named Tootsuki Yaya possesses the ability to perceive things others cannot. After being attacked by a monster-spider, she is saved by a puppy. When she removes a peculiar ribbon from its neck, the puppy transforms into the Wolf King from the demon world. Having been freed after a millennium of imprisonment in a dog's body, the Wolf King seeks revenge against the holy maiden responsible. Tootsuki Yaya is revealed to be the reincarnation of this maiden. The story also includes the one-shot "Wolf's Familia."
