Ichigo Hoshimiya is a bright young girl who is always helping her mother out at a takeaway bento place. After accidentally messing up her brother Raichi's photos of top idol Mizuki Kanzaki, Ichigo goes to her best friend Aoi Kiriya, who manages to get them some tickets to Mizuki's concert. The three of them go to Mizuki's concert, which leaves a strong impression on Ichigo.

On their way to school, the girl's meet the peculiar Otome Arisugawa, who fell into the school fountain trying to catch a rainbow. Meanwhile, a tournament is held for one of three places in a special Christmas event, with Ichigo to face Otome in the first round.

Orihime decides to give the members of STAR☆ANIS a day off by renting out part of a water park. As the gang slowly assemble, Mizuki gets delayed due to some sudden radio work. To lighten up the mood, Aoi suggests they have a water sports contest, which soon draws a crowd.

One year after Ichigo left for America, a new rival idol school, Dream Academy, has been formed, raising its own idols. Meanwhile, at Starlight Academy, where Otome is the current Starlight Queen, Aoi and the others meet a peculiar girl, though can't identify her amongst the listed idols.

Soleil announce they will be launching a half-year long nationwide tour in the spring, setting up a project room at Starlight Academy to plan the tour.

Receiving encouragement from Sumire, who still places in the top eight in spite of her failed Fever Appeal, Akari steps up for the final performance. Not only does Akari manage to beat Hinaki and win the title of Starlight Queen, but she also earns the Special A-Rank for her Fever Appeal. During the awards ceremony, Akari is crowned by Ichigo and thanks everyone for helping her get so far. Afterwards, Akari moves into the Starlight Manor, where she finds Sumire and Hinaki waiting to join her in celebration.

Akari is invited out by Ichigo, who treats her to a special made bento to celebrate her victory. After her meal, Akari makes a request to have Luminas and Soleil hold a joint concert together. Following the performance, the other idols bring out a birthday surprise for Akari, pitting her in an obstacle course race against Ichigo for her present. Managing to catch up to Ichigo at the last second, Akari is treated with a spectacular view and is offered whatever present she'd like, which turns out to be a solo concert with Ichigo.
