Rui is an easy-going genius, and a part of Wonderlands x Showtime. He lives by his own set of rules, so sometimes, he can be labeled as a weirdo. He is almost always smiling and can be carried away by his eccentric ideas. Despite the riskiness of them, he does his best to assure safety. Rui has thin, yellow eyes and choppy purple hair with two cyan streaks. His voice is gentle, but becomes strained when excited or curious. He is close to Tsukasa, Emu, Nene and Mizuki.
