Mayu Shimada

A first-year high school girl unrivaled in her talent for singing and dancing. Originally the first Center Girl for the I-1 Club, various circumstances caused her to quit and leave for Sendai, where she was eventually found by Matsuda and unsuccessfully scouted for the Wake Up Girls! project. She eventually joins the idol group, realizing that she loved singing and dancing to the point where she couldn't give them up no matter what and that she wanted to try to find happiness, at least for herself.
