Yu Takasaki and Ayumu Uehara are wandering around Odaiba when they see a school idol named Setsuna Yuki performing and are totally moved. They find out that she actually goes to their school, and they go check out the School Idol Club she belongs to.

Kasumi refuses to accept the fact that the School Idol Club has been disbanded and decides to take matters into her own hands. Meanwhile, Karin tries to track down the elusive Setsuna Yuki.

The former members of the School Idol Club confront the student council president about her true identity. Meanwhile, Yu gushes about Setsuna Yuki to Nana, and Nana sheds some light on why Setsuna might've quit being a school idol.

Ai and Rina join the School Idol Club. The members are impressed with how much Ai seems to be helping them out and then Ai makes some unexpected discoveries on her own.

The girls start to make PVs for themselves. Emma wants to be an idol who can make everyone feel all warm and fuzzy inside, and they try to figure out how to visualize that. Emma tries to get Karin to join the club but she seems very opposed to that idea.

Rina has always had a hard time communicating with others, but after joining the School Idol Club, she makes the decision to try to change once and for all by putting on a solo performance.

Kanata's little sister, Haruka, is a school idol at Shinonome Academy and comes to visit Kanata at her club one day. The sisters are very close, but Haruka is worried that Kanata is pushing herself too hard and makes a drastic decision.

Shizuku lands the leading role in an upcoming play for a joint drama festival Nijigasaki and another school are having. However, she loses the role when the Drama Club president tells her that she's unable to truly put herself out there.

The Nijigasaki High School Idol Club is invited to perform as school idols at Diver Fest. But there's just one catch... Each school participating will only be able to perform one song.

The School Idol Club start their training camp to prepare for their upcoming concert, but something seems to be bugging Ayumu...

The girls propose the School Idol Festival to the student council, but the process to get the application approved seems harder than they thought it would be.

Things are a little awkward between Yu and Ayumu after their encounter the night before, but everyone continues to prepare for the upcoming School Idol Festival. Yu tries one more time to tell Ayumu something.

The day of the School Idol Festival is finally here. Will everything go according to plan?

Lanzhu and Mia arrive in Japan. The School Idol Club starts creating a promotional video for the 2nd School Idol Festival.

As the girls prepare for the festival, they get a request from Y.G. International Academy to do a joint concert. Emma invites Lanzhu but she declines. Kasumi, Rina, Kanata and Emma follow Lanzhu when they hear she's going to have another surprise concert.

Kasumi, Rina, Kanata, and Emma are excited to perform together, but they're all very different. There isn't much time left before the joint concert, so Rina proposes they all take turns to explain what they want to do, but they still can't seem to agree.

Karin meets Misato Kawamoto, Ai's neighbor. Ai invites Karin to go together with them. Meanwhile, the student council decides to merge the School Idol Festival with the Culture Festival, with Shioriko managing both events.

Shioriko arranges a pre-show produced by the drama club for the day before the cultural fair. Later, Shizuku tells Yu that she wants to create a unit and perform with Ayumu and Setsuna at the Fair. The next morning, Ayumu and Setsuna follows Yu and Shizuku after finding them together.

Setsuna hesitates revealing her identity as Nana Nakagawa, as she thinks her personas should be kept separate. Meanwhile, Kaoruko Mifune, a new music course teacher, praises Yu about the combined event.

The Joint Festival begins. During their time at Shion Academy, the club learns of Kaoruko's past as a school idol, and how Shioriko, her younger sister, looked up to her, hoping to be a school idol herself.

The final day of the 2nd School Idol Festival has arrived. Today, the festival is happening along with Nijigasaki's cultural fair. But Yu still hasn't finished writing the song for the School Idol Club because she wants to make it the best song possible.

The 2nd School Idol Festival came to a successful close. But then Lanzhu tells the girls that she's going to quit being a school idol and head back to Hong Kong. Mia asks her why she's going home, but Lanzhu just says she's done everything she wanted to.
