YoMiko

A modern young miko named Kuri has taken residence at Mikage's shrine. But Kuri has a secret. Long ago, she was a priestess who had a torrid relationship with Akura-oh. She sealed his yokai form along with her own soul into a talisman, her power keeping him in check. But the seal has begun to break, and she has been forced to take human form to protect Akura-oh from escaping.
