** One of [[https://schoolido.lu/cards/6/N-Nishimura-Fumie-Cool/ Nishimura Fumie's N cards released in April 16, 2013]] had her reading a manga with a character resembling Joesph Joestar, which also became a turning point to a crossover concept that is ultimately reinforced by the fandom.

* FunnyAneurysmMoment: The [[https://i.redd.it/dqsijfprtm2z.png 37th chapter of TenFes (Transfer Student Festival) reveals that Jennifer is afraid of Sayuri posing with a]] '''''[[https://i.redd.it/dqsijfprtm2z.png pair of rifles]]'''''. Given Jennifer's bloodline, this might have been an (unintentional) nod to the controversial school shootings in Americ.

** Remember Mari letting out a BigOMG in the vein of [[Manga/JojosBizarreAdventure Joseph Joestar]] in Episode 12 of the anime's first season? The international promo UR set has Mari representing the USA, wearing an outfit that resembles... you guessed it, Joseph Joestar.

* CounterpartComparison:
** Several idols wear resemblance to some from ''VideoGame/TheIdolmaster: Cinderella Girls'': for example, Christina is a blonde nun with a foreign name (like Clarice from CG) and Sachiko is a grey-haired girl with twintails and second-grade syndrome (like Ranko from CG)
** While this comparison may be a stretch, Shizuku Osaka shares a few similarities to Hilda from ''VideoGame/PokemonBlackAndWhite''. Both are brunettes with blue eyes and a slightly pale skin tone, both are considered {{Ensemble Darkhorse}}s in their respective fandoms and both are exclusive to one game in their respective franchises (SIF for Shizuku and [[{{VideoGame/PokemonBlackAndWhite}} Pokémon BW1]] for Hilda).

* AcceptableTargets: KLab.

** Several fans pointing out the Pigeon jokes from ''[[Anime/TheBraveFighterOfSunFighbird Fightbird]]'' on a story mode cutscene of chef Ruby holding a cake while claiming that she's reading a book has became a (coincidental) AscendedMeme as the [[https://i.schoolido.lu/c/1829idolizedRuby.png Deceomber 14 release of the idolized card actually has her with a butterfly]].

* HolyShitQuotient:
** A bug (occurred on December 5, 2018) on the ''After School Activity'' arcade suddenly featured the Aqours members being ''completely nude''.

*** If one made researches of how nuns work, One must realize that someone might have going against the [=YohaRiko=] pairing in the November 19, 2018 release of the nun-themed cards for Riko and Yoshiko.

* MemeticLoser: Almost every player themselves, as the majority of the memes consists of them being [[SelfDeprecation self-deprecating]] for not getting their [=URs=] and their lament to the game's seemingly crappy luck.

** Setsuna Yuki and Karin Asaka consistently compete with each other in the ''PERFECT Dream Project'' polls; Setsuna is considered to have an excellent design and voice, while Karin's mature design and [[MsFanservice... assets]] have won over a lot of people.

** Setsuna Yuki and Rina Tennoji consistently compete with each other in the ''PERFECT Dream Project'' polls; Setsuna is considered to have an excellent design and voice, while Rina has a character gimmick (hiding her face with a drawing of her face to express her emotions) that many fans consider very {{Moe}}.

* BaseBreakingCharacter: Karin Asaka from ''PERFECT Dream Project'' is explicitly designed and pitched as a sex appeal character. As ''Love Live!'' is known for avoiding sex appeal whenever possible, this had rather polarizing responses from the fanbase.

** In the main series, Dia is Eli's biggest fan. Fast forward to ''All Stars'', and the two of them can be seen in the background chatting it up in the opening movie, essentially making it an AlternateUniverse dream come true.

* LesYay: Apart from the other SIF characters, Karin and Ai are '''already shipped''' (although in a slow start) to each other before ''All Stars'' was released, which also continues the legacy of Third Year Blonde and Purple Hair couples like [=NozoEli=] and/or [=KanaMari=]. (Although this ship breaks the cycle due to the two girls' different ages.)

* SuspiciouslySimilarSong: When the extended preview of Setsuna Yuki's solo "CHASE!" was released with the Tokimeki RUNNERS reveal, jokes about it being a ''LightNovel/SwordArtOnline'' theme song started circulating. The song has general stylistic similarities to the ''SAO'' series theme songs, and Setsuna sounds somewhat like [=LiSA=] at certain points. It also helps that her voice actress' most famous role was as the protagonist of ''LightNovel/SwordArtOnlineAlternativeGunGaleOnline'', LLENN, and performed said anime's ending song.

** Half of the [=YohaRiko=] fans are not happy that the Punk Rock set's Riko is used as an SR instead of the UR to complete the game's first proper Yoshiko-Riko UR combo. Meanwhile, ''some'' of the fans are upset that Ruby, [[IncorruptiblePurePureness of all people]], is the UR of the set.

* BaseBreakingCharacter: Karin Asaka from ''PERFECT Dream Project'' is explicitly designed and pitched as a sex appeal character. This... had rather polarizing responses from the ''Love Live!'' fanbase.

** Find one fan who "misinterprets" some of the character's lines as their SexComedy-based quotes.

*** Half of the [=YohaRiko=] fans are not happy that the Punk Rock set's Riko illustration is used as an SR instead of the UR to complete the proper Yoshiko-Riko UR combo for the first time. Meanwhile, ''some'' of the fans are even upset that Ruby from [[IncorruptiblePurePureness all of the characters]], is the UR of the set. The SSR artwork for the Circus set, on the other hand...

*** Every/Most of Chizuko's (female) fans are not entirely pleased to the official artists for drawing her in (occasional) sexualized outfits and/or poses (at least one of her artworks had suffered a slightly bad anatomy).
*** Speaking of bad anatomy, Jennifer & Emma Verde's cards is also this.
*** Later averted in the [[https://schoolido.lu/cards/1706/SSR-Sakamaki-Chizuko-event-Pure/ newest card released at Sept. 5, 2018]], which featured a non-sexualized pose.
