With a week until Christmas, Sakura is put in charge of preparations for the Christmas Party, which includes a special Aikatsu Christmas Stage. Aiming to audition for the stage alongside Akari and Sumire, Hinaki decides she needs to get a Vivid Kiss Premium Dress so she can perform a Heroine Appeal. While trying to find out top designer Kayoko's whereabouts, Hinaki reveals she was previously rejected by her three years ago as she felt she was missing something. Orihime informs her of a party Kayoko is holding, which only the most fashionable people can attend, so the girls take Hinaki clothes shopping, managing to pick out some fashionable coords. On the day of the party, an accident leads to the girls' clothes becoming ruined, but Hinaki manages to find a way to make them even more fashionable in the process. Feeling that Hinaki has found what she was missing; a fashion sense of her own, Kayoko allows the girls into their party and has Hinaki perform on stage, deciding to make her a Premium Dress.
