You had perfect life,you lived with your best friend that you sometimes called a sister.Yes,she was a human and you a Youkai but you still get along pretty good.You are a Youkai that is trapped inside of a ring that your bff is wearing on her hand.Today is 13 years of you and your friend knowing each other,so you went out to buy some food when you two met a 18 year old boy called Ushio Aotsuki. Things were never the same again.
