Rui is a show director and performer. He loves tinkering with machinery and often features the robots he builds in his shows. Because he gets so absorbed in his interests and does things that shock those around him, he is often called a weirdo. However, his actions are all for the sake of creating shows that everyone can enjoy regardless of boundaries.
