Kanon Shibuya takes the entrance exams for the music programme at Yuigaoka Girls' High School, but she fails her singing test and ends up taking the general curriculum; Keke Tang from her class asks her to be a school idol with her.

Realising that she still loves singing, Kanon decides to become a school idol, but Ren Hazuki insists that school idols are not needed at Yuigaoka; Kanon tries to find Ren's weakness with Chisato's help, only to find out that many students trust her.

Kanon once again finds that she cannot sing in front of others; Keke and Chisato try to help her overcome her fear, but after nothing works, Keke suggests that only she will sing as long as Kanon is with her on stage.

Kuukaa wins the special newcomer award at the Yoyogi School Idol Fes and the director allows them to continue their school idol activities; Sumire Heanna joins the club to fulfil her showbiz dreams.

With the addition of Sumire, the Yuigaoka School Idol Club now has three members; as they're cooling off from the heat at Kanon's house, Sunny Passion unexpectedly visits them, who invites the girls to perform with them at their home, Kozushima.

Kanon and her friends train with Sunny Passion for their next concert; Chisato is training for her dance contest; Ren spots Chisato's withdrawal letter to the school; Kanon and Chisato talk over the phone, but they seem distant.
