Tsukasa is the successful Chief Executive Officer of a national corporation who mysteriously wants to become an idol. She is believed to have hired the Producer, rather than been scouted by him. She earned vast amounts of wealth through stock trade, and simply wants to have a professional singing career.

In the tie in Cinderella Girls Theater skits, Tsukasa is introduced by Meiko Namiki. She is both a CEO and an idol, and often uses business terms to describe events.
