After Riko heads off for Tokyo for her recital, the others ask You to take her place alongside Chika in their dance routine. Riko performs her recital while Aquors perform at the preliminaries, both managing to perform well.
The girls are left stunned by St. Snow's performance, even though they failed to win, and the gap between them and the top school idols hits harder when they discover they ranked in last place with zero votes.
Aqours passes onto the National with 1st place ranking. However, the number rises and reaches 98 but the school is decided to be closed. The wish of every student reaches them, and cheers Aqours up once again.
With the School Idol Club approved, Chika and the others begin cleaning up their new clubroom. Afterwards, Hanamaru convinces Dia to listen to Ruby as she states her true wishes. Ruby joins the idol club.
Mari Ohara states that if the girls can fill up the school gym with audience members, she will approve their School Idol Club. While Aqours performs, a power outage occurs while Dia secretly hooks up a backup generator.
Dia realizes that Kanan and Mari seem to have gotten closer to the other members of Aqours while she hasn't, and starts wishing that they would call her "Dia-chan."
