Andy, a stuffed bear made by Rizumu's mother Sonata, tells Bearchi about Sonata's past, where she competed for the title of the Prism Queen against Kyoko. After returning from retirement, Sonata trained rigorously for a year to perform the legendary jump "Aurora Rising" under Kei Takigawa's guidance; however, she is warned that "Aurora Rising" requires her to devote herself to Prism Shows only and sacrifice things important to her. Once she performs it successfully, she leaves Rizumu and her husband behind out of guilt for sacrificing her time with them to train.
