Riku-78
He has a secret that he keeps from Sora and Kairi. At night, when everyone sleeps, he likes to go out on his roof and practice his magic. He likes to see the weaving tendrils of blue and black around his hands and it's something that only he can do. He feels a little guilty and a little dirty and a little dark, but he thinks of the lessons he's learned from Mickey and he feels humble again.
