松本都
In her childhood, Shida practised both judo and kendo, reaching third-dan in the latter. She later embarked on a career as an actress, most notably working on the television series "Muscle Venus", forming an idol group with fellow cast members Hina Kozuki, Ichiko Mayu, Miyako Matsumoto, Sachiko Koga, Tomoyo Morihisa, Tsukasa Fujimoto, Yuki Ueda and Yuri Natsume. In 2009, Shida was cast in the leading role in a film titled "Three Count", set in the world of professional wrestling and also starring veteran professional wrestlers Emi Sakura, Kyoko Inoue and Yoshiko Tamura. For the role, Shida began training under Sakura at her Ice Ribbon dojo and after the conclusion of the taping, decided to find a new career in professional wrestling, joining Ice Ribbon with fellow cast members of both "Muscle Venus" and "Three Count", Ichiko Mayu, Miyako Matsumoto, Sachiko Koga, Tomoyo Morihisa, Tsukasa Fujimoto and Yuki Ueda, though only Shida, Matsumoto and Fujimoto lasted more than six months, making new careers out of professional wrestling.
