Rui Kamishiro is a high school student, the leader of the musical troupe Wonderland X Showtime, and a good-natured genius. Many consider him an eccentric due to his unique way of thinking; he lives by his own rules. He uses his talent to invent on shows or just test things at school. At school with Tsukasa, he is known as the weirdo duo. They sometimes have lunch together on the roof and since Rui doesn't like vegetables, he will ask to trade with his friend, and if he refuses, he will fake cry
