History Anime / LoveLiveSuperstar

** Unlike preceding groups, they seem to have adopted live-action music videos as a norm rather than an exception.

** LoonWithAHeartOfGold: For all of their quirks, they're also genuinely kind and supportive individuals, and do their best to help their friends in difficult situations, as indeed Keke did with Kanon and Shiki did with Mei.

* OOCIsSeriousBusiness: In Season 2 Episode 9, Sumire suggested that only the second years would perform in order to defeat Wien in the Tokyo Regionals. [[spoiler:She gets into a fight with the usually levelheaded Kanon, escalating to the point where Kanon shouts angrily at her]].

* SuddenlyShouting: In Season 2 Episode 9, [[spoiler:Kanon]] suddenly angrily shouts at [[spoiler:Sumire, for her suggestion to bench the first years in order to increase their chances of winning the Tokyo Regionals against Wien]].

* UnreadablyFastText: A small detail seen in Kanon's phone in Season 2 Episode 11 explains how Wien, a middle schooler, can compete in Love Live, a high school-only tournament:[[spoiler: Wien attends an international school so school starts later for her. After summer break, Wien is a first year high schooler and thus eligible to enter Love Live]].

** In Season 2 Episode 3, Liella once again competes in the Yoyogi School Idol Festival, this time without Sunny Passion competing. [[spoiler:However, it is revealed that they lost to the much younger Wien Margarete off-camera. They only win the honorable mention award for their second time at the festival.]]

** The main school idol groups in ''Superstar!!'' are partially inspired from previous main groups: Liella! closely resembles µ's, inheriting their TeamHandStack and overall tone of their discography with tracks such as "Starlight Prologue"; Sunny Passion is a school idol duo from a sunny seaside town, taking cues from Aqours and Saint Snow of ''Sunshine!!''; Wien Margarete is a solo school idol from overseas whose personality and backstory is similar to the ''ALL STARS'' version of Nijigasaki's [=R3BIRTH=] members.

** At the beginning of Season 2, [[spoiler:Liella! are invited to attend the Yoyogi Idol Festival again and without Sunny Passion there, they expect to get a win. However, they're handily beaten by a solo school idol, Wien Margarete, who is still only a 3rd year middle school student.]]

** Stars. The project is named "Superstar", the group's logo has a star, the PV for ''Hajimari wa Kimi no Sora'' as well as promotional material are all filled with star imagery. Liella! also has a star-shaped hand sign in the ending animation, similar to how Aqours had a "0" hand sign for its ArcNumber.

** The ChildhoodFriend doesn't join first; in fact, she takes longer to join than three of the other five members.

* DreamRealityCheck: Keke demands to get pinched by Sumire, when her [[FanGirl most beloved]] Idols "Sunny Passion" had entered the room. But the reality check failed, because here limbs got numb from all the ice she ate before.

* LockedOutOfTheLoop: [[spoiler:Any evidence about Hana's career as a school idol is explicitly hidden from Ren; nothing was left behind in the Hazuki mansion, the Director explicitly kept Hana's school idol memoribillia out of Ren's reach, and Ren never thought to check the School Idol Club to see if her mother left anything there. This causes her to convince herself that her mother regretted her experience as a school idol and takes out her frustrations on Kanon's school idol group for the better half of Season 1.]]

** In Season 2 Episode 5, Keke and Mei, in response to assuming Natsumi wanted to join their group, remark how they've finally gained nine members and that school idol groups in the past have historically made miracles happened once they gathered nine members, referencing how µ's and Aqours won the Love Live competition during their respective runs.

* OOCIsSeriousBusiness: In Season 2 Episode 9, Sumire suggested that only the second years would perform in order to defeat Wien in the Tokyo Regionals. [[spoiler:She gets into a fight with the usual levelheaded Kanon, escalating to the point where Kanon had shouted angrily at her]].

** While the student council is temporarily in management of clubs in the school, the director stops Ren's attempts to block Keke and Kanon's School Idol Club because it's not in her place to tell general course students what they can or can't do.
** Kanon's PerformanceAnxiety simply doesn't go away after performing in front of a crowd once, and her struggle to overcome it in addition to Keke's chances of fulfilling her school idol dreams weighing on her mind becomes a major focus of Season 1 Episode 3.

** The first years are too intimidated on trying out the school idol club since it would be very hard to keep up with the current members, who are also gifted and/or experienced in various ways.

* ShownTheirWork: Ren's gaming room in Season 2 Episode 7 is home to a vast array of video game consoles gifted to her by her father as a rather expensive apology for the whole ParentalAbandonment deal. Her collection is all based on real life game consoles [[WritingAroundTrademarks with minor changes to get around trademarks]] and includes a UsefulNotes/PlayStation2, [[UsefulNotes/XboxSeriesXAndS Xbox Series X]], a [[UsefulNotes/SegaGenesis Sega Mega Drive]] (with 32X and CD attachments), a UsefulNotes/SegaDreamcast, a UsefulNotes/PlayStationPortable, an UsefulNotes/AtariLynx, a UsefulNotes/GameBoy, a [[UsefulNotes/NintendoEntertainmentSystem Famicom]], an UsefulNotes/AtariJaguar, a Playdia, a {{Platform/Pippin}}, a [[UsefulNotes/TurboGrafx16 PC Engine]] with CD-ROM attachment, a [[UsefulNotes/SuperNintendoEntertainmentSystem Super Famicom]] (with {{UsefulNotes/Satellaview}} attachment), a UsefulNotes/PhilipsCDi, an {{UsefulNotes/Xbox}}, a UsefulNotes/ThreeDOInteractiveMultiplayer, a UsefulNotes/SegaSaturn, a UsefulNotes/SegaGenesis, a UsefulNotes/PlayStation, a UsefulNotes/GameBoyAdvance, a UsefulNotes/GameAndWatch or a Game Boy Micro (Famicom Edition, no less), {{Toys/Tamagotchi}}, the original ''{{Toys/Digimon}}'' Digivices, a UsefulNotes/NintendoSwitch, an UsefulNotes/Xbox360, a UsefulNotes/Nintendo64, a UsefulNotes/SegaMasterSystem, a UsefulNotes/PlayStation4, an NES, and (of all things) the ''{{UsefulNotes/SNESCDROM}}''.

* SpellMyNameWithAnS: Keke and Kanon's {{Portmanteau}} school idol name is variably spelled as either "[=KuuKaa=]" or "[=KeKa=]" since the name explicitly comes from the "ke" in "Keke" and "ka" in "Kanon", but Keke writes the "ke" in katakana using the Japanese equivalent of her name's Chinese pronunciation. It's notable to point out that Keke herself spells it as "[=KuuKaa=]" on the banner she designed.

* SenpaiKohai: In Season 2 Episode 1, Kanon got really excited at being called senpai by Kinako.

** With Wien Margarete and Tomari Onitsuka joining Liella! in the third season, this is the first entry to have the main group have more then the standard nine members.
