Kanon Shibuya takes the entrance exams for the music program at Yuigaoka Girls' High School. But she fails her singing test and ends up taking the general curriculum. She is approached by Keke Tang from her class who asks her to be a school idol with her.

Realizing that she still loves singing, Kanon decides to become a school idol. However, 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.

The girls have to place 1st at a local festival to stay school idols. Chisato & Keke try to help Kanon get over her fear but nothing works. Keke tells Kanon she'll sing alone this time. Meanwhile, one of the most prominent groups, Sunny Passion, joins the festival.

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...

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.

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

After a successful show at Kozushima, the School Idol Club welcomes Chisato, their 4th member. They are now starting a new term and find out there will be an election for the student council president. If Ren becomes president, it may affect their club.

Ren is carrying the burden of Yuigaoka all alone since it's the school her late mother left behind. She asks Kanon & the others not to mention this even though she's facing backlash for saying that the school festival would be put on by the music program.

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...

The girls decide on the group name "Liella!" and enter the Love Live. For the regional prelims, they find out that they have to rap. While the others struggle, Sumire displays impromptu rap skills and Kanon nominates Sumire as the center, but...

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.

Did you succeed in the solo stage at your alma mater? The survival of the school has been decided, and love live with the five enthusiastic people! The outline of the Tokyo tournament arrives. The content was a remote format, and each district representative used the net to relay the live broadcast live. In other words, you have to prepare the stage yourself. It seems that Kanon isn't very particular about what kind of stage he should make while everyone comes up with ideas.

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.

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.

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.

A new school year has begun at Yuigaoka Girls' High School. Liella! is practicing up on the roof as usual, and a new student named Kinako Sakurakoji is drawn in by their voices. She ends up sneaking into the school and quietly watches them train and...

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.

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...

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…

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…

Liella! now has 9 members after Natsumi joins and the Love Live is finally announced. There is no set theme this time for their song, so they excitedly get to work on it. Ren agrees to write the song, but Mei notices that she's been acting strange lately.

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.

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.

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.
