Love Live! Superstar!!

Kanon is suddenly told her plans to study abroad are cancelled, and the remaining members of Liella! are trying to figure out how to fill the hole that Kanon has left behind. Meanwhile, Margarete tries to make a new School Idol Club at Yuigaoka.

Natsumi's little sister, Tomari, joins the New School Idol Club and they begin their activities as Tomakanote. Their first show is an upcoming remote concert, but their motivations concerning school idols are totally different, causing some friction.

Liella! feels motivated more than ever after seeing Tomakanote's remote concert. To show Liella!'s new potential, Chisato chooses Shiki for the next center. Shiki is unsure why she's chosen for the center and passes out during practice from the pressure.

People start to wonder what the future holds for Liella! & Tomakanote. The two groups bump into each other one day during training. They have a little scuffle, then Natsumi & Tomari run off somewhere. The girls chase them & they somehow end up in Ushiku.

1st term is over and summer vacation is about to begin at Yuigaoka. The 1st gen students are one step closer to graduation so Keke and Kanon talk about their futures, but Keke is unsure of hers. During break, the girls head to Shanghai.

Keke always thought that studying hard and doing well in school was everything, but something changed in middle school. Liella! gets a chance to perform at the Shanghai Fes because of Mengmeng. Meanwhile, Keke decides to go to college after high school…

Liella! and Tomakanote had a successful performance in Shanghai. Liella! wants Tomakanote to join them, but Margarete still wants to beat them and Tomari also declines. But only one group can go to the Love Live. Kanon's solution is a sleepover?!

Nishimura finds Natsume coming to visit him each night at his house, but something seems strange…

Liella! is finally all together. The 11 girls start training together, but Margarete is having trouble fitting in. Kanon wants Margarete to fit in, so she asks her to think of the formation for their next performance.

Liella! is preparing for the Tokyo tournament and Kanon asks Kinako to write the lyrics for the new song and Kinako hesitantly accepts. Meanwhile, Ren was trying to find someone to take over as student council president.

Kanon heads to Vienna alone to finish her enrollment paperwork. Keke, Chisato, Sumire, and Ren decide their career paths for after they graduate. Meanwhile, the 2nd years try to come up with a song to ensure their victory at the Love Live.

Yuigaoka Girls' High School's first graduation ceremony is just around the corner. The first and second-years of Liella! are preparing for a third win at Love Live, so the third-years write one final song for them just before they graduate.
