Aikatsu on Parade!

Raki Kiseki, a second-year middle school student, transfers to Star Harmony Academy with dreams of becoming an idol. One day, she uses an Aikatsu Pass given to her by her older sister, an Aikatsu engineer, and something strange occurs. Multiple doors appear before her, and when she opens them, she encounters Aikatsu idols she's never met, like Yume Nijino from "Aikatsu Stars!" Inspired by these encounters, Raki decides to create her own premium dress and perform in it on stage.
