Hi, I am searching for a Sesshoumaura and his father story. It is about Sessy father and how when Sessy was a small child his father hit him so hard that he hit his head on a wall or screen. Sessy lost his sight from the injure and his mother never forgave his father. Because he is blind and the only heir to the throne his mother faked his death so he could leave and received special training. The father thinks he really killed his son and is beyond depressed. It is an old story from two or three year backs maybe even more. Thank you for your help.
