The story is set in the Yuigaoka Private Girls High School (私立結ヶ丘女子高等学校, Shiritsu Yuigaoka Joshi Kōtō Gakkō) that lies between the Omotesando, Harajuku, and Aoyama neighborhoods of Tokyo. The school was originally going to be demolished, only to have instead recently reopened to accept students. Within a school that has not made a name for itself, along with no history or accomplishments to speak of, Kanon Shibuya and four other first-year students discover the existence of "school idols", and for one reason or another eventually join the school idol club (with the group later being named "Liella!") in order to leave their mark on the newly reopened academy. As time progresses, Liella! gains popularity with the general public and prospective students, which leads to new members joining with each consecutive school year. The number of club members gradually rises from the founding 5 in its first year, 9 in its second year, and 11 in its third year.

Where appropriate, plot descriptions mentioned below refer to the anime television series. Other parts of the franchise, such as the manga and novel series, feature some variations in the storyline. The original five members are first-year students in the first season and advance as second-year students in the second season.^[3]

Kanon is a high school second-year student who claims to be "someone with no standout characteristics." She has a fond appreciation for both singing and playing the guitar. However, she tends to tense up when she is set to perform in front of other people, which has caused her to pass out on several occasions on stage. Because of this, she failed the entrance exam for Yuigaoka Girls' music program, and ended up settling for the school's general academic program instead. However, thanks to Keke, she overcomes her stage fright and becomes very cheerful and happy again. Kanon is also a very kind, charismatic and selfless girl, who constantly tries to help, encourage and befriend everyone, even the ones who are arrogant and dismissive towards her. Her family consists of a dad who works as a translator, a mom who runs a cafe, and a younger sister. She and her younger sister often help their mother with running the cafe, with one of her specialties being latte art. She keeps a chubby Eurasian scops owl as a pet named "Manmaru," which is also the cafe's popular mascot. She wears glasses and ties her hair up when at home.

The project's name, Love Live! Superstar!! was announced in July through the series' exclusive magazine Love Live! Days.^[9] In September, the school idol group's name, "Liella!" was also chosen through fans' votes.^[10] The name was chosen among 16 options that fans could vote for.^[7] The name "Liella!" comes from a combination from a French word "lier" which means "to connect", which is the same as Yui (結) in the school's name in Japanese, and "brilliante", which means an "inner glow". Behind the group's name lies the feelings of the hope that the small stars of today who have their own brilliance will become superstars someday.^[11]

The cast of the initial five main characters was later revealed in December 2020: Sayuri Date, Liyuu, Nako Misaki, Naomi Payton, and Nagisa Aoyama. Date and Aoyama are members who passed the open audition that was held earlier in the year.^[12][a] The group's debut single, "Hajimari wa Kimi no Sora" (始まりは君の空) released on April 7, 2021.

In June 2021, the Love Live! staff issued an apology for having modeled the main character's family café after the exterior of Café Casa, a real café in Shibuya. The staff admitted that they had used the café’s likeness without permission or "prior consideration", leading to the café's staff receiving infringements of their privacy via social media; additionally, the increased presence of Love Live! fans at the café affected its intended mood and atmosphere. The design of the café in the anime was subsequently changed so it less resembled Café Casa.^[26]
