After running into each other while practising their candid expressions, Ichigo, Aoi, Ran, Seira, and Kii go shopping together to explore the range of expressions they can make, before stopping by Seira's café.

The presence of a reporter known as Mister S, who is infamous for exposing idol love affairs, puts the other idols on high alert. Meanwhile, Aoi and Kii are asked to participate in a fashion show themed around 'first love'. Feeling that Mister S may be targeting Seira, Kii has her take asylum in Starlight Academy, as she feels her secret hobby of cutely talking to cats clashes with her rock idol image.

After producing a successful makeup commercial for Seira, Kii is lined up to audition for the poster girl of her favorite beverage, Brain Thunder.

Given the chance to appear in a special episode of Idol Princesses, Maria decides to invite her friends from both Dream Academy and Starlight Academy to a house party at her mansion.

Seira, Kii, Sora, and Maria are invited to audition for a four-girl drama series. Unable to decide on which roles to audition for, they let Kii's computer choose for them, with Kii ending up as the leader character. The girls ask Ichigo, Aoi, and Ran for advice on drama auditions, learning how to utilise their skills to fit their assigned roles and make them their own.

Aoi is requested to appear in a concert promoting a Futuring Girl Constellation Dress, in which she is expected to perform a Constellation Appeal.

Afterwards, Maria comes across Otome at a kindergarten, which is revealed to be Otome's home, and helps her with preparations for a play of The Wizard of Oz.

As Mizuki and WM reach the top of Aikatsu Ranking charts, Mikuru is tasked by Mizuki to reach the top ten rankings of the individual charts, suggesting that she needs to obtain a Premium dress from Vivid Kiss' top designer, Kayoko, who is currently in America. Whilst pondering about how to accomplish this, Mikuru is tasked with growing and delivering a golden Miracle Flower, which requires watering at specific times of the day whilst also working around her busy schedule.

Ran is invited to audition for a drama based on Aladdin alongside Sora, who is also asked to design outfits for the audition.

Whilst awaiting WM's performance, Mikuru worries that she won't be able to match Soleil's performance, but Mizuki gives her some assurance, stating she chose to face Soleil because they would be tough opponents. Meanwhile, Ichigo receives a call from Ringo, who states it is thanks to WM's appearance that Soleil is able to shine as a legend.

Aoi is requested to produce and star in her own music video to promote Futuring Girl. As Aoi struggles to come up with an idea in the short time she's been given, she hears from Yurika about how her commercial was built up from a simple idea, inspiring Aoi to use a fashion show as the basis for her music video.

Ichigo and Seira start thinking about what outfits they should wear for their concert against WM, struggling to come up with an exciting coordination.
