Tsukasa Tenma is the leader of the musical troupe Wonderland X Showtime. Tsukasa is a loud, boastful, and eccentric guy who can often get carried away. He does his best to allow the troupe to be better and often helps Rui (director) with his inventions. But lately his friend had become less active and seemed not to be enjoying the show. He tried to talk to him. Things got worse when he seemed to have no strength to do anything at all (similar to depression), and Tsukasa tries to take care of him
