Katsuyuki Kamiyama is Ruon's creator and a scientific genius (called a modern Von Neumann).


Katsuyuki created the AI Ruon based on his daughter who he had killed. While trying to contact Ruon, Katsuyuki attacks and severs Teruki's connection, thus proving to be a formidable opponent for Mimi who is an accomplished hacker. Later in Episode Four, Rin sees Ruon shooting him.
