Sonata's Winter

Finally, it is Rizumu's turn to perform. She performed Super Stardust Shower, then performing the Aurora Rising. After doing so, she goes backstage and faints. At the hospital, her father Ryutaro tells her the back story of her mother, Kanzaki Sonata. Sonata was an orphan, and at a young age she worked. She was a lonely girl, and she had no means of living. But that all changed when she saw a video of Kyōko Asechi's performance at the Prism Queen Cup. Kyōko performed Platinum Spiral which made her Prism Queen. Sonata comments that although she won, she wasn't happy. Sonata started practicing to perform in a prism show at the park and while working in a rink. After a few years she won at the Pure Crsytal Tiara Cup. She later met Ryutaro at a park. Later Ryutaro proposed to Sonata with a pure crystal high heels prism stone. After giving birth to Rizumu, Kyōko answers the questions of the media, saying that Sonata is not yet retiring, to which Sonata saw in TV. Sonata asks Ryutaro for permission to perform once again in the Prism Show. After arguing, Ryu finally agrees. Sonata performs in the Prism Queen Cup, wearing the Pure White Wedding Dress, Pure Crystal Tiara, and the Pure Crystal High Heel that Ryutaro have her. She won the cup by performing the Aurora Rising. After hearing this, Rizumu says that Sonata did not leave them because of Ryutaro not agreeing to what Sonata wants. Later Mion and Aira learns that Rizumu fainted because of hunger.
