Who Takes the Tiara of Victory!?

When Aira and Rizumu were eating, three girls went into their room and stole both of their prism stone cases. But Aira had her stones that she was gonna wear in the finals in her back pocket and told Rizumu that they didn't take hers which was a lie. Then she gave her prism stones to Rizumu. Rizumu's performance topped first place before she found out that Aira had lied to her and was being way too considerate of Rizumu. When Aira takes the stage, the same 3 girls come out to embarrass her about her normal clothes. Aira started to cry until she knew that she had to get up. Without knowing it, she begins to do a perfect stage that overwhelms everyone. Aira wins but then Mion appears after being gone for a while makes a performance to beat Aira because of her Star aura that surprised Mion before and now she wants to win or come back to the prism show.
