Rui Kamishiro

Rui lives by his own set of rules, which causes people to consider him a weirdo. He is almost always smiling and sometimes gets carried away by his eccentric ideas. This includes using people as test dummies for his ideas and waterboarding them in swimming pools, Despite the apparent riskiness of his ideas, Rui does his best to take safety into consideration.

Rui also has levels of curiosity that borderline on obsession, 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, he sometimes jokes about putting people in danger but he doesn’t mean it.

Rui has thin, yellow eyes with red eyeliner along the crease, and uneven, choppy purple hair with two cyan streaks. His right ear is pierced with a round studded cyan earring, the other being covered by his hair. His voice is gentle, though it becomes strained when he is excited or curious.

Nene's neighbor and childhood friend, Rui is an easy-going genius. He's meticulous about making every show the best it can be, making use of his flair for technology and inventiveness. He even builds robots to use on stage. His somewhat unique way of thinking often gets him labeled as a weirdo.

Rui and Nene are next-door neighbors, as well as childhood friends. Rui was the one who recommended she join Wonderlands x Showtime. He manages the groups' 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. Rui's father is a robotics engineer and his mother is a biologist.

When Rui was young, he loved to create shows and tried to include his classmates in them. However, due to his eccentric nature and risky ideas, his classmates grew to dislike doing shows with him and pushed him away. Rui eventually decided that he would perform shows on his own, using robots as his actors instead of real people. He can often be seen performing guerrilla shows on the street or in Phoenix Wonderland, which causes security to chase after him.

Despite his independence, deep down, Rui has the desire to perform shows with other people again. He is given this opportunity when he joins Wonderlands x Showtime, and appreciates how Tsukasa is willing to try his inventions and stage directions.

Nene is one of his Fellow group members and a friend. The two are neighbors and childhood friends, and although Nene thinks of him as a weirdo, she is still shown to be very caring towards him, with occasional concerns about his mental health. When they were young, Nene had struggled with talking to people. To try and combat this, Rui created Robo-Nene to serve as an avatar that Nene could talk through, which helped to an extent. They were both inspired to take up theatre after seeing the same play. Rui was also the one to invite her to join the troupe, having known about her talent and hobby for singing. She agrees, but chooses to perform through Robo-Nene due to her anxiety. In the Main Story, Rui is glad to see that Nene has found the courage to stand onstage by herself again.
