A high school girl with exceptional talent in singing and dancing was once the star of her school's I-1 Club. However, due to certain events, she left the club and moved to Sendai. She was later discovered by Matsuda and tried out for the Wake Up Girls! project but failed. Despite this setback, she eventually joined the idol group and realized that singing and dancing brought her immense joy, which she couldn't give up on no matter what. In pursuit of happiness, at least for herself, she decided to continue with her passion.

It was revealed that her quitting the I-1 Club was due to her standing for her ideals against I-1 Club's strict environment. Standing up against I-1 Club's President for firing one of her friends despite her desire to continue working for I-1 Club, he cornered her into an ultimatum, claiming that if her single sold less copies than the other single that was being released simultaneously featuring a new Center Girl, she would be fired.
With her singles selling less, she was forced out of I-1 Club, followed by a flurry of presumably baseless scandals (presumably crafted solely to permanently damage Mayu's reputation) and her parents divorcing, resulting in Mayu living with her Mother in Sendai. Scarred by her experiences in the Entertainment Industry, she idled in Sendai, unsure as to how she should move on with her life despite still loving the idea of being an Idol, singing, and dancing.
