Personality: Overwhelmingly confident narcissism. He has a very eccentric personality, but is considered the most mature because he apologizes immediately if he thinks he's done something wrong. Along with Nene, he's one of the relatively sane ones in Wonderlands x Showtime, but he's still called Weirdo Number One alongside Rui due to his unique narcissism. He calls himself Weirdo One and Rui Weirdo Two. (Conclusion: He's not entirely normal either) He once confessed to Emu and got rejected(...) He still has lingering feelings for her. He seems to be the worst at studying among the four members. He has a younger sister, Tenma Saki, who is one year younger (same age as Emu and Nene, in Emu's class). Tsukasa is a self-proclaimed doting brother, and Saki also treasures her brother, so they have a very good relationship. He's stuck on the school rooftop due to the chemicals, and he's only half-committed to the idea of escaping. He's also worried about Saki(...) His voice is loud enough to exceed 120 decibels. He bickers often with Nene, and Rui is always trying to perform strange experiments on him. He still has feelings for Emu after his confession was rejected. He calls Emu 'Emu', Rui 'Rui', and Nene 'Nene'.
