Cyo

Brother to Ryo, he visits the White Abyss, but does not stay long. He prefers to live in his world, the world of the Wing Children. Even still, he cannot stay there very long either. His responsibility in these worlds is to monitor them and be sure to keep them running smoothly. 

He does not like knowing he is a character in a story and being one of the few who remain self aware no matter what world he is in.
