Due to reasons not known (at the moment) Katy abandon her son Wolf (unwillingly), and lived in the Human World as a English teacher. Years later, she is found by her son, now a teenager, who tells her that Wolf Daddy has asked for her to come back to the Demon World. She tells Wolf that it is no use, since she has used up all her magic to stay alive in the Human World, but that Wolf might have inherited her magic, and offer him to teach him how to use it, if he will go in her place to Wolf Daddy.
