Suinshin runs the Star Shrine, which is the Shrine with the lowest amount of Light but the highest number of individual Lights in all of Chuuten. Suinshin is weak, but of noble character. He ordered Nanshu to go to Gaiten to confront the Darkness, because Nanshu is the only one who can change his body in a way that is suitable for Gaiten. Nanshu severed his head and face from his body and left his body behind in Chuuten. He will awaken if given the Glowing Fire where you can give him The Seven Stars he will transform it into a more powerful or stronger Seven Stars that can be used to retrieve your eye.
