Aikatsu on Parade!

A second-year middle school student enrolls at Star Harmony Academy with the goal of becoming an idol. After using an Aikatsu Pass given to her by her older sister, who works as an Aikatsu engineer, she encounters a strange phenomenon—numerous doors appear, leading her to unfamiliar Aikatsu idols like Yume Nijino. Inspired by the experience, she decides to create her own high-quality dress and perform in it on stage.
