Rui is a show director and actor. He loves tinkering with machines 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 people from all walks of life can enjoy. Now, as a member of Wonderlands×Showtime (WandaShow) alongside Tsukasa, Emu, and Nene, he creates shows that bring smiles to many. He is tall, kind, gentlemanly, and mature. He is intelligent and cares deeply for his friends. He has a sadistic streak and an air of sexiness, but he also has a childish side, hating vegetables and tidying up.
