An eccentric and brilliant inventor and theater director. He likes to joke on his friends, put on spectacular shows, and build robots. He hates vegetables and love sweets.
Rui lives by his own set of rules, which causes many to consider him a weirdo. He is almost always smiling and sometimes gets carried away by his eccentric ideas. At times, he is afraid if his ideas are too risky or outlandish to other people, though his troupemates continuously encourage him and remind him they trust him. Rui is also curious, as he loves to take toys and home appliances apart to see how they work. He cares deeply for his friends. He is also a teasing and playful person, with an example being his constant ideas for performances that often involve putting Tsukasa's life in danger.
Dreams of becoming a first-class director and actor
Rui was the one who recommended her to join Wonderlands x Showtime. He manages the group's stage performances and is both an actor and stage director. Rui is also very skilled in inventing machinery and creates animatronics for the shows, including NeneRobo. When Rui was young, he struggled to get along with his peers due to the differences what they found fun and interesting. Rui finds a love of theater and decides to put on shows with his classmates. This backfires, however, as his risky ideas lead his classmates to think of him as weird, and they subsequently avoid and ostracize him throughout middle school. He is given this opportunity when he joins Wonderlands x Showtime, and appreciates how his troupemates are willing to try his inventions and stage directions. He met Mizuki in middle school, became friends, and accepted their non-binary identity. In high school, they communicated less, but soon fell in love after working on a joint project.
