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.

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.

Having made it through the regional qualifiers, Liella! was preparing for the next Tokyo tournament. While they were writing a song, Kanon recommended Kinako to write the lyrics. Kinako accepted the request from the first-generation members, who wanted the second- and third-generation members to step forward and shine more, but... she began to worry about the pressure of the tournament. At the same time, Koi was also struggling with choosing a successor for student council president. Worried about Koi, Kinako decided to help her find a successor...

The losing team will have to grant one wish from the winning team. That was the promise Liella! and Tomakanote made for the school festival. Two members from each team: Mei, Natsumi, Tomari, and Margarete, were chosen to make the song for the competition.

Kanon is suddenly told that her study abroad was cancelled. At school, the remaining Liella! members continue to practice, determined to make up for Kanon's absence. Meanwhile, Margarete, who has become a student at Yuigaoka, establishes a "New School Idol Club" to compete with Liella!. However, Kanon sees a reflection of her former self in Margarete, who is unable to recruit new members. Kanon is torn between returning to Liella!, who she already said goodbye to, and isn't sure what decision she should make...

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.

Liella! gets past the regional prelims. Chisato quietly tells the other second-years about the skill difference between them and the first-years, which may affect them going to the finals. Keke thinks things are fine as they are but Sumire seems uneasy.

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! 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?!

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! 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.

After Mei and Shiki join, Liella! now has 8 members. Natsumi Onitsuka finds out about Liella!'s popularity and tells them that she wants to produce them through her company. Liella! agrees so they can concentrate on their training, but Sumire has doubts.

Liella! wins at the Tokyo Tournament, but Wien is unable to accept this fact and storms off. The girls celebrate their victory at Kanon's home, then head to their first shrine visit of the new year. Meanwhile, Kanon wonders why Wien really came to Japan.

Liella! is invited to be the headliner at a school idol fes that they performed at last year. While Kinako is nervous about her first big performance, one of the other performers named Wien Margarete lets her powerful voice resonate through the venue.

Liella! holds a strategy meeting for the Love Live. This year's Love Live will be held remotely, meaning the stage they use needs to stand out. Kanon tries to figure out a symbol that represents Liella! and their school so they can create the right stage.

The director suggests to Kanon that she transfer to the Vienna National Academy of Music, but Kanon's unsure. Chisato also wants Kanon to go so she can make her dream come true, but Kanon's worried about Liella!, so she decides not to go, but…

The first-years go off to do their own thing during the summer which worries Kanon, but the others tell her it's a good thing that they're working hard on their own. Meanwhile, the first-years are at Kinako's home in Hokkaido with Natsumi for training.

Ren joins the School Idol Club, making the member count 5. Meanwhile, the next Love Live is announced and the finals will be at Jingu Stadium. Even getting to the prelims will be hard, but the girls decide to enter. They have to input a group name and...

With the addition of Sumire, the Yuigaoka School Idol Club now has 3 members. As they're cooling off from the heat at Kanon's house, they are unexpectedly visited by Sunny Passion, who invites the girls to perform with them at their home, Kozushima.

Liella! now has 6 members after Kinako joins, but no one joins after that. According to Kinako, the reason is because there were rumors that the training was too hard. Liella! decides to make their training regimen simpler to attract new students but…

Kuukaa wins the special newcomer award at the Yoyogi School Idol Fes and the director allows them to continue their school idol activities. Meanwhile, Sumire Heanna joins the club to fulfill her showbiz dreams, but when they try to decide the center...

lovelive! Liella !, who showed her presence on the stage of the district qualifying, successfully passed the qualifying. At that time, Kanon and Chisago's alma mater's elementary school asked me to sing "Liella!". I agree, but I'm afraid. The elementary school stage was once the stage where the first incident that triggered Kanon to be unable to sing in public occurred. Chisago, who knows Kanon at that time, tells everyone about it again.
