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.
