When Riley Anderson first moved to San Francisco, she hated her life there. The pizza was terrible, the students at school were too cool to hang out with her and wore bad-smelling perfume and nail polish, the kids had more talent at hockey than she did and her friend Meg broke up with her. This lead to her stealing her mother's credit card and running away to San Francisco. In the Mind World, this wound up sending her imaginary friend Bing Bong to the memory dump due to Honesty Island's collapse. When Bing Bong fades away, a cyalume charm lands in the area where Riley was when Bing Bong faded away. A young girl, Momoko, who is on vacation with her brother, Sennosuke, and her baby sister, Aiko, finds it and wonders why it was left there. It summons a young girl with pink hair with donut-shaped buns and green eyes, and a purple shirt with green pants She can only say the word "Okay?" and is carrying a bag with candies on it. Momoko takes her into PriPara, and she begins to speak normally and asks her to help her find her way back home, since she knows that this isn't where she was born. She tells her that she was someone else in another time, and that she belonged to the family of a young girl. Momoko then learns that the reason for her turning into a charm was that the answer to who she used to be lies in PriPara. She and Momoko agree to be partners, and they perform their first live together, which is a success.
