History Anime / LoveLiveNijigasakiHighSchoolIdolClub

** Season 2 Episode 4 shows "Arch Jacoes" and "Diezel", imitations of Marc Jacobs and Diesel. Episode 10 has a "Jonga" game.

** Lanzhu is back in her uniform after performing "Eutopia" in Season 2 Episode 1, but she wears the music video outfit in Episodes 3-4.

** The character designs in the second season are more streamlined and refined from the first season to look more consistent for the rest of the characters.

** Karen and Emma's date in episode 4 leads them to the Miraikan, a museum dedicated to science. Emma sings her song at the Geo-Cosmos section, with its real-time weather pattern globe changing into a sphere of flowers for the occasion.

* AnimationBump: Episode 11 has noticeably more significant use of cinematography techniques than the other episodes in the season, many of which convey an eerily unsettling sense of isolation and distress.

** Some Japanese traditions seen from previous series and game adaptations, such as visiting shrines, weren't present. This makes the show generally accessible to viewers given the fact that many scenes take place inside the school.

** Yu often mentions the word "tokimeki/thrill" throughout Season 2. [[spoiler:This led to composing the song "TOKIMEKI Runners" for the 2nd School Idol Festival with Mia's help.]]

** The 2nd Season in general, in spite of introduction of their rival member [[spoiler:Lanzhu Zhong]], has less drama and tention than the 1st Season and from ''ALL STARS''. It helps that the main conflict of the school and its members are completely absent here.

** The entire 2nd Season, in spite of introduction of their rival member [[spoiler:Lanzhu Zhong]], is generally less drama and conflict than the 1st Season and from ''ALL STARS''.

* NoNameGiven: The president of the Nijigasaki Drama Club as well as Nana's Vice President go unnamed in the anime series and are only referred to by their titles whenever they're addressed. The twin secretaries in Nana's student council were ''originally'' this, until their appearance in ''ALL STARS'' confirms that their [[NamedInTheAdaptation names]] are Satsuki and Uzuki Sato.

** Shioriko Mifune definitely qualifies for this trope in the anime, while Lanzhu Zhong and Mia Taylor tend to vacillate between this and JerkOfAHeartOfGold. While they do maintain some core traits that they had in the source material, differences in backstory and circumstances have altered how they interacted with the School Idol Club. Any negative traits were either toned down (Mia, who is still somewhat aloof and standoffish, but helps Yuu composing and then joins), characters were able to establish a level of respect even if there is disagreement (Lanzhu, who is still a bit stuck-up and arrogant but respects the group and ends up swallowing her pride when she joins) or even support the cause of the School Idol Club, even if they don't want to be one themselves or decide to join only later on (Shioriko, who is the nicest and even before she joins is shown to be nothing but supportive and kind towards the group).

* SlidingScaleOfAdaptationModification: Type 2. There are enough similarities with the story of ''ALL STARS'' Season 1 that it can be considered an adaptation of it, but the anime strips out almost all of the plot and only leaves in a few key details from both the beginning and end of the season. Almost all the characters, while bearing ostensibly similar personalities, are rewritten significantly from their game counterparts, and the focus of the show is changed to almost exclusively focus on the characters themselves. Many key characters from the game are AdaptedOut, changing how the show approaches some plot details, and the fact that Yu Takasaki is a similar but distinctly different enough character from the PlayerCharacter of ''ALL STARS'' significantly changes how some character dynamics are handled.

** Shioriko Mifune, Mia Taylor and Lanzhu Zhong definitely qualify for this trope in the anime, as while they do maintain some core traits that they had in the source material, differences in backstory and circumstances has altered how they interacted with the School Idol Club. Any negative traits were either toned down (Mia), characters were able to establish a level of respect even if there is disagreement (Lanzhu) or even support the cause of the School Idol Club, even if they don't want to be one themselves. (Shioriko)

** Unlike her non-anime appearances, Kasumi isn't seen wearing her moon hairpin in the anime. [[spoiler:Shizuku gifts her the hairpin at the end of Episode 13.]]

* CanonImmigrant: In TheStinger to Episode 12, the club's live concert name is revealed to be [[spoiler: "Nijigasaki First Live with You!", the name of an actual concert in 2019. It even uses the same logo]].

* TheCameo:
** Himeno Ayanokoji and Koyuki Shirase, two N card girls from ''VideoGame/LoveLiveSchoolIdolFestival'', show up together on the cover of a school idol magazine Karin owns in episode 5.
** Christina and Kasane Hasekura, also from ''SIF'', have voiced cameos in episode 7. The rest of the Shinonome Academy members, except Rika Kamiya, appear there as well, though unvoiced. There's also a Hitomi Shiga lookalike seen in the same episode, however that may be a subversion as said lookalike was wearing a [=NijiGaku=] uniform...
** Likewise, Misaki Shido appears alongside Himeno to watch the play Shizuku's in during episode 8.
** Episode 9 has the most "N girl" cameos in Season 1, with the previously missing Rika being present[[note]]although with a noticeable AdaptationDyeJob - her hair being a much darker shade of gray than in the game[[/note]], as well as the remainder of Touou Academy. No new voice though...
** Fumi Shitara, another N card girl attending Touou, appears with her chameleon Gyoro in one of the stills near the end of episode 13.

* ContinuityCavalcade: The vast bulk of Episode 13 features references to all of the previous episodes of the season. All of the girls are seen wearing their outfits from their respective solo songs during the episode, and clips from their songs play throughout the episode. [[spoiler:"Yume ga Kokokara Hajimeru yo" not only has the girls performing in their solo song outifts, the music video parts features stills from all of the previous episodes, and each girl has unique choreography taken directly from their solo.]]

** Season 2 Episode 4 shows "Arch Jacoes" and "Diezel", imitations of Marc Jacobs and Diesel.

** In Season 2 Episode 10, Rina shows off an AugmentedReality smartphone game she made called "[=NijiGaku=] GO". It's reminiscent of ''VideoGame/PokemonGo'' and uses a similar map screen to it, but here the girls must find different cats.

* VariantCover: The {{Insert Song}}s in the first nine episodes of the anime are released on [=CDs=] in groups of three. However, there are three cover art versions for each CD release, one for each character whose solo is found on the release. The actual musical contents of the [=CDs=] are identical regardless of cover art. Completionist fans who want all the covers would thus need to buy three copies of each release.

** Yu often mentioned the word "tokimeki/thrill" for the remainder of Season 2. [[spoiler:This led into composing the song "TOKIMEKI Runners" for the 2nd School Idol Festival with Mia's help.]]

* SurprisinglyRealisticOutcome: While ''Nijigasaki'' has lesser doses of this compared to the original and ''Sunshine'', there's still one major case of this when the girls present their proposal to host their festival in episode 11. [[spoiler:As Kanata said after Yu and Kasumi explained what happened, they thought that they would more easily get the approval to host the festival because Setsuna (or rather Nana) is their StudentCouncilPresident. Unfortunately, because the initial documents were incomplete and lacked details such as not listing a place to host the festival, the proposal was rejected and the girls had to resubmit their application after sorting out things such as the venue(s) of the festival and who they're going to be working with.]]

** The story is generally more upbeat than ''ALL STARS'', Nijigasaki's source material. Largely due to the absence of [[spoiler:Shioriko Mifune]] and far fewer trope deconstructions compared to the game, there are very few major obstacles that the girls encounter throughout the story.

* {{Eyedscreen}}: Contrasting all of the other insert songs, [[spoiler:Kanata's "Butterfly"]] is done in a cinematic {{Letterbox}} style, although there is a particular shot where she stands ''in front'' of the screen.

** Yu often mentioned the word "TOKIMEKI/thrill" for the remainder of Season 2. [[spoiler:This led into composing a song "TOKIMEKI Runners" with Mia's help for the 2nd School Idol Festival.]]
