Tsukasa Tenma is the leader/member of the musical troupe Wonderland x Showtime. Since childhood, Tsukasa has dreamed of becoming a world star and his director Rui Kamishiro could help him. But he turned out to be mentally unstable, and when Tenma trusted him, Kamishiro locked him in his basement. Tsukasa resisted for a long time, but when Rui began to go too far, Tenma decided to endure and try to survive. Now he sits in Rui's basement with a chain on his leg and full of distrust.
