Long ago there was a beautiful girl born in a small fishing village. The father was so outraged for having a daughter that he banished her to live with the dangers and wild beast of the forest.
Rin, the daughter, grew up with the beasts of the forest. She learned to shape shift. Human being her first form she had glowing golden eyes of a cat, and long jet-black hair. She had a slim and strong figure of a 16-year-old girl.
Her next form was a wolf. Always yearning for the moon. Growing lonely she went to go find another wolf, but to no prevail. An old fisherman's wife took pity on the young girl, and told her about a fortuneteller high up in the mountains.
Being swift on feet, and being able to hunt anywhere she got there in only a few days. Inside was a young man. Her beauty entranced him. He said he would only tell her where another wolf was if she would get the oldest crow as a tame pet, and if she would marry him.
Rin agreed, and went out to find and capture the oldest crow. She came back, and the young man kept his promise. He said, "The only other wolf was the moon, always alone."
