History Main / HighSchoolAU

* ''Literature/GiJoeClassified'' by Kelley Skovron is a series is about the "Average Joes" school club attempting to work against the Cobra organization.

* ''ComicBook/Switch2015'' is a LighterAndSofter ([[AdaptationalModesty and much more modest]]) ''Comicbook/{{Witchblade}}'' AU in a high school setting.

** Back in the '80s, there were plans for an ''X-Men'' cartoon that would've featured ComicBook/{{Cyclops}}, ComicBook/{{Storm}}, ComicBook/KittyPryde, Nightcrawler, Colossus, Thunderbird and ComicBook/MsMarvel as teenagers attending a public high school. It never got off the ground, though.

* ''WesternAnimation/YoungJustice'' gives several established DC superheroes cameos as non-powered high school students. Karen Beecher ([[Comicbook/DoomPatrol Bumblebee]]) and Mal Duncan ([[Comicbook/TeenTitans Herald]]) appear as classmates of Superboy and Miss Martian, while Barbara Gordon (Comicbook/{{Batgirl}}) and Bette Kane ([[ComicBook/{{Batwoman}} Flamebird]]) attend the same school as Artemis and Dick. Most notably, ComicBook/{{Zatanna}} (who is almost always depicted as an adult in the comics and other adaptations) is made the same age as Dick Grayson. Most of these characters received their powers / superhero personas sometime during the five year timeskip between seasons 1 and 2. They are now in their late teens and early twenties and affiliated with either the League or the Team.

* Featured in ''ComicBook/{{Deadpool}} Corps'', with Kid Deadpool living in one such world.

** The OELManga ''Manga/XMenMisfits'', which cast a few characters like ComicBook/{{Storm}} and Beast as young teachers, but made the rest of the cast into teenagers.

** ''WesternAnimation/LegionOfSuperHeroes'' does fall into this, by adapting the pre-Crisis ComicBook/{{Superboy}}'s adventures with the titular team, as its first season came out in the fall of 2006, the same year ''Film/SupermanReturns'' was released.

* The ''Anime/{{Pokemon}}'' 20th anniversary film ''Anime/PokemonIChooseYou'' has a DreamSequence where Ash imagines himself going to elementary school. Instead of being late for his first Pokémon, he is late for school. It's implied in the sequence that Pokémon don't exist in that world.

** ''WesternAnimation/TransformersAnimated'' for ''Film/{{Transformers}}'' - the main cast are an inexperienced RagtagBunchOfMisfits rather than war veterans, and the human sidekick is a kid rather than a high-school student.

* The [[https://youtu.be/XjLdLmn2Kw0 second ending credits sequence]] for ''Manga/{{Naruto}} Shippuden'' is set in a High School AU, joining and legitimizing the thousands of ''Manga/{{Naruto}}'' fanfics that have already used this trope. Ironically, it also went ''against'' lots of clichés that were (and still are) extremely common in Naruto high school AU fics. It portrayed Naruto as a HotBlooded gang member instead of a normal but waifish outcast. OTOH Hinata remained a shy ShrinkingViolet (albeit one who is assertive enough to directly ask Naruto out), Sakura remained a Type B {{Tsundere}} ready to slap Naruto if needed, Rock Lee was the sports star, Neji was both the ArrogantKungFuGuy AND the StudentCouncilPresident, and Sasuke was the local Bad Boy and Naruto's rival who still aided him during fights. This was expanded upon in a bonus feature, created by the animators, for the seventh Shippuden DVD called ''[[Anime/ShippuKonohaGakuenDen Shippu! Konoha Gakuen Den]]'' which consists of narrated still-frames, in which Naruto [[ToBeAMaster seeks to be the leader of all in the yakuza in Japan]] and we see him beating the other fighters in the school, and also features [[ShipTease Naruto and Hinata actually going on a date]] while several others (Sakura, Ino, Shikamaru, etc.) [[DatePeepers spy on them]].

* ''Anime/BubblegumCrisis'' was adapted into a High School AU LightNovel, ''Hard Metal Guardians'', in 2012. Sylia is an ElegantGothicLolita, Linna is a rich girl working in a {{Meido}} cafe to understand how ordinary people live, Nene has GirlishPigtails with Leon as her older brother who still works in the A.D. Police, and Priss is still in a rock band.

* ''Anime/IsekaiQuartet'' is a {{Crossover}} anime series that is an ''official'' High School A.U. It brings together four LightNovel-based {{Isekai}} series published by Kodansha (''Literature/{{Konosuba}}'', ''Literature/{{Overlord|2012}}'', ''Literature/TheSagaOfTanyaTheEvil'', and ''Literature/ReZero'') and puts them all in a single high school classroom, while keeping their original outfits from their home series. The second season adds characters from ''Literature/TheRisingOfTheShieldHero'' as well.

* ''LightNovel/GakuenKino'' is a High School ''MagicalGirl'' AU set of spin-off novels for ''Literature/KinosJourney''. Thankfully, the writers know and revel in how silly this is.

* ''LightNovel/TheDevilIsAPartTimer'' has a manga adaptation where the main characters are in school instead of the fast food industry.

* ''LightNovel/GakuenKino'' is a High School ''MagicalGirl'' AU set of spin-off novels for ''LightNovel/KinosJourney''. Thankfully, the writers know and revel in how silly this is.

* ''Anime/IsekaiQuartet'' is a {{Crossover}} anime series that is an ''official'' High School A.U. It brings together four LightNovel-based {{Isekai}} series published by Kodansha (''LightNovel/{{Konosuba}}'', ''LightNovel/{{Overlord|2012}}'', ''Literature/TheSagaOfTanyaTheEvil'', and ''Literature/ReZero'') and puts them all in a single high school classroom, while keeping their original outfits from their home series. The second season adds characters from ''Literature/TheRisingOfTheShieldHero'' as well.

* Not exactly an ''AU'', but ''[[LightNovel/{{Slayers}} Slayers NEXT]]'' and ''Slayers TRY'' feature fun little illustrations that bookend the commercial breaks, like a lot of anime do. Sometimes they actually pertain to the episode, but usually they're just fun illustrations showing what the characters would look like in a more modern setting. Favorites include [[GenkiGirl Amelia]] the sailor-style school girl, Zelgadis the rock star, and Gourry as a daycare attendent.

** A gag ending in the original manga has Eren waking up to discover that the entire series was AllJustADream and that he and Miksasa are actually normal Japanese teenagers. Likely a ShoutOut to the ''Evangelion'' fake-out ending mentioned below.

* ''Series/KamenRiderDecade'', in its distortion of past series, changes ''Series/KamenRiderFaiz'' into a high school AU. Former QuirkyMinibossSquad Lucky Clover is reimagined as a clique of the cool kids and Tsukasa becomes a student for his duration in this world.

* The Creator/MegCabot Novel ''Literature/AvalonHigh'' is pretty much a published version of this. It's Myth/KingArthur... in a high school!

* ''Series/{{Merlin|2008}}'' has been described as "The High School AU of the Myth/KingArthur legend". Certain changes, including making Merlin and Arthur the same age (late teens, early twenties) and a [[AnachronismStew loose interpretation of history]], definitely fit the trope.

* ''Anime/IsekaiQuartet'' is a 2019 {{Crossover}} series that is an ''official'' High School A.U. It brings together four LightNovel-based {{Isekai}} series published by Kodansha (''LightNovel/{{Konosuba}}'', ''LightNovel/{{Overlord|2012}}'', ''Literature/TheSagaOfTanyaTheEvil'', and ''Literature/ReZero'') and puts them all in a single high school classroom, while keeping their original outfits from their home series.

* This happened in an episode of the ''Anime/TenchiMuyo'' TV series. Not content to leave it at that, however, the writers also threw in {{Magical Girl}}s. Unsurprisingly, given the amoeba-like manner in which ''Tenchi Muyo'' split off {{alternate continuit|y}}ies, this world became [[Anime/PrettySammy a series all on its own]]. [[Anime/SasamiMagicalGirlsClub Two different series, in fact]].

* The ''Manga/SamuraiDeeperKyo'' manga has a series of audio drama CD set in the alternate 'Samurai High School' setting, stemming from a piece of art drawn by the creator for one of the manga volumes. Strangely enough it is highly probable that said creator is actually female (pseudonyms are funny that way).

* ''Anime/TengenToppaGurrenLagann'':
** There is an audio drama CD set in a high school where Kamina is basically a misfit failing school, Simon is the sole handyman/janitor, and Nia is the Student Council President...until they kick all that to the ground like everything else and turn the whole thing upside down. [[http://community.livejournal.com/gurren_lagann/157779.html Read the script here.]]
** ''Gurren Lagann'' also has a ''second'' official High School AU in the form of the manga ''Tengen Toppa Gurren Lagann Guren Gakuenhen''. All the good guys attend Dai Gurren Academy, which is located right next to the menacing and intimidating Teppelin Academy, headed by malicious principal Lord Genome. Note that all of the Beastmen are still Beastmen, and [[UnusuallyUninterestingSight no one finds this odd]]. Highlights include Kamina getting ''very'' confused over the meaning of "{{moe}}", Yoko in a [[{{Joshikousei}} sailor uniform]] inducing MarshmallowHell to Simon for ''three whole pages'' (while continuing to talk), and Viral dressed in a business suit (coinciding with the "ViralMarketing" [[MemeticMutation meme]]). Oh, and Nia wears [[Anime/NeonGenesisEvangelion Rei's]] transfer student uniform (see below) and calls Simon her husband... and ''takes the [[Anime/{{Gunbuster}} Buster Stance]]''. Plus, this manga sheds some insight into how Kamina and Nia [[WhatCouldHaveBeen would fare]] [[spoiler:had Kamina not died before Nia arrived into the plot]]. Leeron is also in a dress and Lord Genome is the overprotective dad of Nia. Nia and Simon pull off a sequence very similar to [[Anime/MobileFighterGGundam Love Love TenKyoKen]]

* ''Anime/GalaxyAngel X'' has one for one episode, complete with the requisite AnimeThemeSong this type of show would have. The end of said theme song is interrupted by ringing cell phones.

* ''Manga/TokyoMewMew'' had a kindergarten AU in the manga, entitled ''Petite Mew Mew''. Interestingly, the characters' natures as magical {{Animorph|ism}}s were ''emphasized'' rather than discarded; for example, Lettuce/Retasu is a finless porpoise ''all the time'', and has to be carried around in a fishbowl.
* Later episodes of the ''Manga/DGrayMan'' anime have a High School AU {{Omake}} at the end.
* ''Horitsuba Gakuen'' is a series of crossover drama [=CDs=] starring the characters from ''Manga/TsubasaReservoirChronicle'' and ''Manga/XxxHolic'' in a high school setting.
* ''LightNovel/GakuenKino'' is a High School ''MagicalGirl'' AU set of spin-off novels for ''LightNovel/KinosJourney''. Thankfully, the writers know and revel in how silly this is.
* Spoofed by Hiromu Arakawa more than once with ''Manga/FullmetalAlchemist'' omakes. They usually involve Edward and Alphonse in a gang (not a very good one at that) or Mustang and the Fuhrer in a girls' school spoofing '70s {{Shoujo}} manga. Don't forget Olivier as a sukeban (member of a Japanese girl gang).
* Similar in the same vein as ''Gurren Lagann'' and especially the second ending credit sequence of ''Naruto'', the third credit ending sequence of ''Anime/EurekaSeven'' skirts this, showing the female cast living out lives normal for (real) women of their ages (given that most of them are High School aged). It's interesting to note that this ending credit sequence was storyboarded by Shinichirō Watanabe. Yeah, ''[[Anime/CowboyBebop that]]'' [[Anime/SamuraiChamploo Shinichiro Watanabe]] ([[CowboyBebopAtHIsComputer but not that one]])
* ''Anime/CodeGeass'':
** Like its [[UltimateShowdownOfUltimateDestiny Internet rival]] ''Anime/TengenToppaGurrenLagann'', ''Anime/CodeGeass'' had a High School AU as one of its audio dramas. Unlike most examples though, the expected roles were reversed; MagnificentBastard protagonist Lelouch is a teacher, his LadyOfWar sister Cornelia is a ''sukeban'', and BigBad Emperor Charles is the leader of the school's gangs.
** Arguably, the manga adaptation with the same name as the anime also qualifies, since it focuses more on Ashford Academy thanks to the removal of the HumongousMecha. The racist military faction is replaced by a racist group of students, and the Japanese rebels commit acts of petty vandalism rather than actual terrorism.
* Creator/TsutomuNihei's ''[[Manga/{{Blame}} BLAME! Academy]]'' gag manga. You only have to look at the art work to realize this is intensely [[CrackFic crackish]] and completely hilarious. Notable for still having killer cyborgs with portable [=WMDs=] & taking place in an unimaginably massive CyberPunk city, which is basically the whole joke. Also unusual as it actually ages one character up, with murderous cyborg loli Sana-Kan becoming a grown woman as one of the teachers.

* The {{OVA}} on one of the ''Anime/KoihimeMusou'' [=DVDs=] has all the main characters attend high school, with highly explosive results.
* ''Manga/IkkiTousen'' is itself a High School AU of ''Literature/RomanceOfTheThreeKingdoms'' (as well as a GenderFlip of most of the characters). [[InvertedTrope Naturally, this means]] there's official art of the ''Ikki Tousen'' characters in ''Three Kingdoms''-era China (or something similar enough to excuse breaking out the {{Breast Plate}}s).
* ''Manga/MagicalGirlLyricalNanohaINNOCENT'' is a manga series used to advertise a {{Collectible Card|Game}} MobilePhoneGame for ''Franchise/LyricalNanoha''...and it is unabashedly a Grade School AU. The magic powers have been replaced with virtual card games, and all of the non-human characters are now humans (except the familiars, which are just normal animals). [[FixFic We also have a good Precia and six other canonically dead characters that aren't dead.]][[note]]seven if you include ''[[VideoGame/MagicalGirlLyricalNanohaAsPortable Gears of Destiny]]'' continuity.[[/note]]
* ''Anime/HeroicAge'''s OST covers feature Dheianeila and Yuti La as high school students in another shoutout to Sukeban Deka.
* ''VideoGame/{{Utawarerumono}}'' has a drama CD with a high school setting.

* ''Manga/{{NEEDLESS}}'' also has a series of High School AU bonus specials, this time set at St. Lily Academy, with Cruz playing a role he would later go on to play in the post-apocalyptic action series, only in a more traditional setting. That role? Crossdresser.
* ''Anime/MartianSuccessorNadesico'' spoofs this with an "Early 21st Century High School" entertainment program in the titular space battleship's virtual reality recreation room, which is essentially a High School AU [[Franchise/StarTrek holodeck scenario]].
* Both of the opening credits to ''Anime/TheTowerOfDruaga'' are set in such a setting.
* Similarly, the fourth ending of ''Manga/BlackClover'' is based on this idea.
* ''Manga/CrayonShinChan'': ''The High School Years!''

* ''Manga/ChronoCrusade'' has an anime-based [[AudioAdaptation Drama CD]] set in an High School AU. The Sinners are in a gang which Chrono is slowly becoming disillusioned with, Rosette is a girl from a Catholic school that Chrono has a romantic interest in, Sister Kate is the principle of Rosette's school while Daffau is the principle of the other school, etc. The cast gets to be {{Large Ham}}s and seem to be having a blast.
* ''Anime/BubblegumCrisis'' was adapted into a High School AU LightNovel, ''Hard Metal Guardians'', in 2012. Sylia is an ElegantGothicLolita, Linna is a rich girl working in a {{Meido}} cafe to understand how ordinary people live, Nene has GirlishPigtails with Leon as her older brother who still works in the A.D. Police, and Priss is still in a rock band.
* ''LightNovel/TheDevilIsAPartTimer'' has a manga adaptation where the main characters are in school instead of the fast food industry.
* ''Manga/NegimaMagisterNegiMagi'' plays with the trope--since the original series already takes place (for half of its run anyway) in a junior high school, one of the spinoffs takes place in a '''kindergarten''' instead, with the students aged down and the (originally child prodigy) teacher and his best friend '''aged up''' to adults.
* ''Manga/AttackOnTitan'' has three examples:
** A gag ending in the original manga has Eren waking up to discover that the entire series was AllJustADream and that he and Miksasa are actually normal Japanese teenagers. Likely a ShoutOut to the ''Evangelion'' fake-out ending mentioned above.
** A later series of gag endings puts the cast into a stereotypical [[EagleLand American]] high school.
** The series also has an official SpinOff called ''Manga/AttackOnTitanJuniorHigh'', though as the name implies, it's technically a Junior High AU; everyone in the series has been transplanted into a modern Japanese middle school setting, including the Titans themselves, who are still towering giants but somehow ''also'' go to school.
* ''Anime/PowerpuffGirlsZ'', an anime adaptation of ''WesternAnimation/ThePowerpuffGirls1998'', featured the girls as three unrelated typical 12 year-old middle schoolers that were given superpowers. It played like a {{Magical|Girl}}... 'scuse me, [[InsistentTerminology Scientific]] [[MagicalGirl Girl]] series.
* [[InvertedTrope Inverted]] in the ''Manga/MyHeroAcademia'' anime. The series takes place mostly in a high school (granted, it's a [[AcademyOfAdventure high school for superheroes]], but a high school regardless). The third ending credits sequence features the characters in a HighFantasy setting. [[EmpoweredBadassNormal Deku]] becomes a clumsy traveller in a rather Bilbo-Baggins-esque get-up (with a sword that's apparently possessed by [[BigGood All-Might]]), Todoroki is a prince on a white horse, Uraraka is a mage, Iida a KnightInShiningArmor, and [[HavingABlast Bakugo]] is a DragonRider. We also get to see all of Class 1-A, who are all featured as some [[AnAdventurerIsYou fantasy class or other]]. The beginning implies this is a class play of some sort.
** In a sense, the series was this to its predecessor ''Manga/{{My Hero|2008}}''. Rather than be about a salaryman taking after his inspiration while on the job, it's about a teen's life at SuperheroSchool with his inspiration as one of the teachers.
* ''Anime/IsekaiQuartet'' is a 2019 {{Crossover}} series that is an ''official'' High School A.U. It brings together four LightNovel-based {{Isekai}} series published by Kodansha (''LightNovel/{{Konosuba}}, LightNovel/{{Overlord}}, LightNovel/SagaOfTanyaTheEvil, LightNovel/ReZero'') and puts them all in a single high school classroom, while keeping their original outfits from their home series.
* Very similar to ''Isekai Quartet'' above, ''Anime/{{Kaginado}}'' uses the same premise of merging multiple franchises together and put them in the same high school without changing outfits. The franchises being ''Creator/KeyVisualArts''' ''VisualNovel/{{Kanon}}'', ''VisualNovel/{{Air}}'', ''VisualNovel/{{Clannad}}'', ''VisualNovel/LittleBusters'', ''VisualNovel/{{Rewrite}}'', and later ''Anime/AngelBeats''. However, only the actual high school characters attend Kagindo Academy, while all the other characters apparently live in the same town or live in their original homes, as evident with ''AIR''. Characters from the distant past are in the present, the series has no fear of spoiling its audience and it makes constantly fun of the TearJerker moments the franchises are known for.
* ''Anime/CrossAnge'' has a spinoff manga called ''Cross Ange: Tenshi to Ryuu no Gakuen (Cross Ange: School of Angels and Dragons)'' where everyone is a regular high school student and there are no deaths.
* ''Franchise/YokaiWatch'' has the ''Yo-Kai Academy Y'' subseries (''[[Anime/YokaiWatchJamTheMovieYokaiAcademyYCanACatBeAHero Can a Cat be A Hero?]]'' and ''[[Anime/YokaiWatchJamYokaiAcademyYCloseEncountersOfTheNKind Close Encounters of the N Kind]]''), which is a fusion between this and the HenshinHero genre. The usual Yo-kai are humanoids and attend the titular school, and since they're already supernatural to some extent, the YSP Watch instead gives them powers.
* While ''Manga/KaguyaSamaLoveIsWar'' already takes place in High School, the ''Official Doujinshi'' spin-off had a series of chapters centering around a Kindergarten AU where Shirogane and Hayasaka are everyone else's teachers. [[spoiler:Notably, it is the only AU where Hayasaka takes Kaguya's place as Shirogane's LoveInterest (though Kaguya still has a PrecociousCrush on him).]]

* ''ComicBook/SonicTheHedgehogArchieComics'': Archie did this to Sonic and his friends in one issue. It was not well-received.

* Featured in ''ComicBook/{{Deadpool}} Corps'', with Kid Deadpool living in one such world.
* ''ComicBook/Switch2015'' is a LighterAndSofter ([[AdaptationalModesty and much more modest]]) ''Comicbook/{{Witchblade}}'' AU in a high school setting.
* ''ComicBook/MystikU'' is a DC AU series featuring various DC magician characters as freshmen at a [[WizardingSchool Wizarding University]].
* The ''ComicBook/HarleyQuinn'' original graphic novel ''Breaking Glass'' features Harley, Joker, and Ivy (who also gets a RaceLift, becoming black) as high schoolers, [[spoiler:with cameos from a teenage Bruce Wayne.]]

* ''WesternAnimation/MyLittlePonyEquestriaGirls'' and its sequels are literally this, being an actual alternate universe from the main ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' series that the characters can travel between whenever they so wish. The cast are reimagined as [[AmazingTechnicolorPopulation technicolor humans]], with many of them either attending high school or working there as faculty.
* ''WesternAnimation/MonstersUniversity'' features multiple of the original film's major characters actually attending college and studying for their future profession as Scarers.

* The ''Anime/{{Pokemon}}'' 20th anniversary film ''Anime/PokemonIChooseYou'' has a DreamSequence where Ash imagines himself going to elementary school. Instead of being late for his first Pokémon, he is late for school. It's implied in the sequence that Pokémon don't exist in that world.
* ''Anime/YokaiWatchJamTheMovieYokaiAcademyYCanACatBeAHero'' is a school AU of ''Anime/YokaiWatch'' set in Y Academy. Jibanyan, Komasan, and several other yokai are now human schoolkids.

* ''Film/EasyA'' set Creator/NathanielHawthorne's ''Literature/TheScarletLetter'' in a high school at Ojai, California.
* ''Film/{{Brick}}'' isn't an AU of any specific noir story, but it still fits here. The movie takes every noir trope imaginable and transplants them into a high school setting. The results are surprisingly good.
* ''Film/AssassinationOfAHighSchoolPresident'' translates conspiracy and thriller-feely tropes to a high school setting. It also features the journalist protagonist, in this case writing for the high school newspaper.
* ''Film/CruelIntentions'' gives this treatment to ''DangerousLiaisons''.
* ''Film/ShesAllThat'' does a very loose version of this for George Bernard Shaw's ''Theatre/{{Pygmalion}}'' (filtered through its more famous adaptation ''Theatre/MyFairLady'').
* The ''WesternAnimation/DoraTheExplorer'' LiveActionAdaptation ages up Dora and deals with her as a high schooler.

* There's a very bad recast of ''Literature/PrideAndPrejudice'' in high school out there.

* For ''Series/{{Lost}}'', we have [[spoiler: [[http://en.wikipedia.org/wiki/Dr._Linus an actual canon episode]] that takes place in a high school in an alternate universe, with Ben Linus, John Locke, and Arzt as teachers, and Alex as a student.]]
* ''Series/LawAndOrderTrialByJury''. Given that these series don't provide much in the way of personality for their characters, except as relates to their investigation and prosecution of crime, the fic was essentially a regular, boring high school experience [[TransplantedCharacterFic using the names]] of ''Series/LawAndOrder'' characters.
* A case of canonical high school having its slate wiped clean is one high school AU for ''Series/PowerRangersInSpace''. The teens never had any powers, and the Red and Silver Rangers, ([[HumanAliens human]]) aliens in the show, were normal school-attending Earthlings here. Though the high school stopped appearing in the show for good around episode 8, which is probably the only reason the fic author could get away with it.
* ''Series/{{Smallville}}'' is an official version of this trope applied to Superman.
* Also ''Series/{{Gotham}}'' but applied to Batman.

* ''Series/{{Merlin|2008}}'' has been described as "The High School AU of the Myth/KingArthur legend". Certain changes, including making Merlin and Arthur the same age (late teens, early twenties) and a [[AnachronismStew loose interpretation of history]], definitely fit the trope.

* ''Series/BecomingHuman'' can be seen as the High School AU of ''Series/{{Being Human|UK}}''.
* ''Series/{{Club}}'' is a miniseries based on ''TabletopGame/{{Clue}}'' that essentially took the characters from the game and made them teens.

* SJ Games' ''Pyramid Magazine'' once had a ''TabletopGame/{{TOON}}''/''TabletopGame/InNomine'' crossover set at Heavenly Heights High School. Laurence ([[IncorruptiblePurePureness incorruptible]] leader of Heaven's armies) was the captain of the football team, Kobal (Demon Prince of [[ComedicSociopathy Dark Humour]]) was the class clown, and so on.

* ''Sweet Little Rock'n'Roll'' from the Creator/TakarazukaRevue sets ''Theatre/MuchAdoAboutNothing'' in an American high school in TheFifties.

* ''Toys/{{Lalaloopsy}}'' has ''Lalaloopsy Girls'', with the characters attending a boarding school of sorts.

* ''VisualNovel/{{Hakuouki}}'' has a sequel that places all the characters in a modern high school setting.

* Re/Visioned made a ''Franchise/{{Tomb Raider}}'' animated series named Pre-Teen Raider with the description "Lara Croft wasn't always one of the world's most successful Tomb Raiders. See how a twelve year old Lara honed her craft during her early years at the Croft Academy." Essentially, the Tomb Raider creators licensed a High School AU of their own game. It is seemingly impossible to find said series, but it is mentioned on the Croft Generation website [[http://http://www.croftgeneration.com/eng/index.php?sec=revisioned here]]
* The ''Private VideoGame/{{BEMANI}} Academy'' event features [[Music/{{BEMANI}} BEMANI musicians]] as students in a private academy, with a comically-middle-aged-looking dj TAKA acting as the principal. The event has you playing (platonic) matchmaker by getting pairs of artists to build up friendship with each other; filling a pair's [[RelationshipValues Friendship gauge]] by playing their "home" game causes the graphic of the pair to change from the pair being distant to becoming best friends. When the pair's gauge reaches 100%, you unlock their respective collaboration song for play in all participating BEMANI games.
* The ''VideoGame/CardCityNights'' series is a MassiveMultiplayerCrossover where characters from ''VideoGame/{{Iji}}'', the ''VideoGame/IttleDew'' series, ''VideoGame/HyperPrincessPitch'' (among others) play card games.
* ''VideoGame/FinalFantasyXIV'' has "Academia Eorzea", which started as an April Fool's Day joke prior to getting a proper greenlight and serialization. It stars the Leveilleur twins, Alisaie and Alphinaud, as first-years in the Academy of Light, after having combined with the Academy of Darkness to make the titular Academia Eorzea ran by principal Tataru. The twins live in the shared home named The Rising Stones, living with the founding Scions as members of the school faculty: homeroom teacher Y'shtola, science teacher Urianger, and PE teacher Thancred.
* In ''VideoGame/GranblueFantasy'', Lowain, Elsam, and Tomoi come up with one in the "L.E.T'S. H.A.N.G." event where the former two are students and the latter an instructor at Albion Military Academy. It's noted that due to it being a fantasy of theirs and not having the full details from Katalina, there are discrepancies from reality. The "Table for Six" event adds Sutera and Korwa as students and Isabella and Jin as faculty members.
* ''VisualNovel/{{Sunrider}}'' released an official AlternateUniverse high school DatingSim called ''Sunrider Academy''.

* ''VideoGame/TheLegendOfZeldaSkywardSword'' isn't so much an [=AU=] of ''Franchise/TheLegendOfZelda'', but it starts off in a boarding school and centers around the students (namely Link, Zelda, and Groose) before TheDragon shows up.
* ''VideoGame/RivieraThePromisedLand'' has this in its Epilogue Disc.
* ''VideoGame/LeagueOfLegends'' features a line of "Academy" skins for several champions (specifically [[{{Joshikousei}} Ahri]], [[TheBully Darius]], [[GadgeteerGenius Ekko]], and [[PrincelyYoungMan Vladimir]], among others retrofitted for the line), which eventually developed into its own AlternateContinuity with its own minor lore blurbs. Riot has officially endorsed a fan webcomic called ''[[https://na.leagueoflegends.com/en/page/academy-adventures-series-1 Academy]] [[https://na.leagueoflegends.com/en/page/academy-adventures-series-2 Adventures]]'', transplanting a much wider range of champions to fit the {{Troperiffic}} setting of Valoran High.
* ''VideoGame/MapleStory'' has the Friend Story theme dungeon, a parallel world where several characters have counterparts in a South Korean high school setting. Notably, the AU is ''integral to the plot'', as not only is one of the playable classes from that world (Kinesis), but the Heroes of the Maple World travel to it looking for information, because the BigBad teamed up with his own counterpart to further his plans.

* ''VideoGame/FateGrandOrder'': While the game isn't a High School A.U. as of itself nor does it contain a story chapter that takes place in a high school, almost all of the characters drawn by Honjou Raita have an alternate version that seems to be designed to take place in a potential high school setting, such as biker Sakata Kintoki, "JapaneseDelinquent" Raikou who acts more like a student council president, literary club member Murasaki, and cheerleader Ibuki-Douji. The only exception to this is with Shuten-Douji and James Moriarty, albeit the latter got a younger version of himself when he was just a math professor.

* Machinima had also funded ''[[https://www.youtube.com/watch?v=9YWoB9jFoVc He]][[https://www.youtube.com/watch?v=HYFOGkqiR1Y ro]] [[https://www.youtube.com/watch?v=TPWkb-XVEEw High]]'', featuring ''Franchise/TheLegendOfZelda'' in a high school environment. While CutShort once the company went under, the series was rediscovered once Creator/RoosterTeeth featured it in the anthology ''Neon Konbini''.
* Website/{{CollegeHumor}} parodies this with their ''Muppet Teens'' skit, though they are not shown in school.

* ''Webcomic/HetaliaAxisPowers'', of all things, has the DatingSim VisualNovel ''Gakuen Hetalia'', penned and illustrated by the author himself and later adaptated into a PSP game (not by Himaruya, though). Because what everybody needs is an AU where [[MoeAnthropomorphism Moe Anthropomorphisms]] of countries who normally make up a CastFullOfPrettyBoys have friendly and/or romantic hijinks with a newcomer country, er, girl in the [[BoardingSchool Boarding School of World]]. (Bad thing is that it made Seychelles, said newcomer country, [[DieForOurShip horribly unpopular among the rabid and jealous fangirls]] who falsely accused her of either "stealing all the bishonen for herself" or standing in between their favorite yaoi couples.) The ''Gakuen'' universe has been expanded in manga strips, and it eventually debuted in the AnimatedAdaptation. Among other things, it has France hanging with China and Turkey in the [[SupremeChef Gourmet Club]], Estonia and Ukraine in the music club, Seychelles peeking into other people's clubs too, etc. It's specially "famous" for introducing Romania, who is a member of the Magic Club with England.

* ''[[http://thendu.com/ The NDU]]'' is basically ''Dumbing of Age'' staring the casts of ''Webcomic/NamirDeiter'' and ''Webcomic/YouSayItFirst''.

* ''WesternAnimation/AllGrownUp'' is actually a television example of the latter, taking the ''WesternAnimation/{{Rugrats}}'' cast, aging them by ten years, and putting them in a fairly standard ''middle''-school sitcom. Which, in the show, is still [[MostWritersAreAdults pretty much like High School]] in every other respect.

* ''WesternAnimation/BatmanBeyond's'' existence is owed to [[ExecutiveMeddling a bunch of higher ups]] going "Let's do a show about Batman in high school." The creators took advantage of the fact that [[ExactWords they didn't specify]] ''Bruce Wayne'' in high school, so instead it's set in a {{Cyberpunk}} future where he's the retired MissionControl for a new Dark Knight. It became surprisingly popular and even [[RetCanon got adapted to the comics]], mostly due to being a lot DarkerAndEdgier than the execs had in mind.

* Inverted in ''WesternAnimation/TinyToonAdventures'', which is not simply ''WesternAnimation/LooneyTunes'' in school, but brand new toons in training who are being taught by the Looney Tunes.

* Craig [=McCracken=] mocked the concept in ''WesternAnimation/ThePowerpuffGirls1998'', where the girls are ditzy morons more interested in shopping and boys rather than saving the town from destruction.
* ''WesternAnimation/YoungJustice'' gives several established DC superheroes cameos as non-powered high school students. Karen Beecher ([[Comicbook/DoomPatrol Bumblebee]]) and Mal Duncan ([[Comicbook/TeenTitans Herald]]) appear as classmates of Superboy and Miss Martian, while Barbara Gordon (Comicbook/{{Batgirl}}) and Bette Kane ([[ComicBook/{{Batwoman}} Flamebird]]) attend the same school as Artemis and Dick. Most notably, ComicBook/{{Zatanna}} (who is almost always depicted as an adult in the comics and other adaptations) is made the same age as Dick Grayson. Most of these characters received their powers / superhero personas sometime during the five year timeskip between seasons 1 and 2. They are now in their late teens and early twenties and affiliated with either the League or the Team.

* ''WesternAnimation/CloudyWithAChanceOfMeatballs2017'' takes place during Flint's high school days and, through some slight retconning, Sam goes to the same school.
* ''WesternAnimation/ExtremeGhostbusters'' is about a second generation of [[WesternAnimation/TheRealGhostbusters ghostbusters]] made of college students.
* ''WesternAnimation/MegaManFullyCharged'' takes this approach to the [[VideoGame/MegaManClassic classic Mega Man series]]. Instead of being a janitorial robot turned fighting robot after one of his co-creators goes rogue, this incarnation of the Blue Bomber is a robot high school student named Aki Light, with Mega Man being his evil-fighting alter ego.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** As stated above, ''WesternAnimation/MyLittlePonyEquestriaGirls'' takes place in an alternate universe where the characters are all human high schoolers. This means most characters have been aged-down ([[VagueAge maybe]]), while others are aged-up (again, maybe).
** Season 8 of the main series has a slight school GenreShift. In this case, however, the main characters are teachers, not students.
* Unlike the SuperheroSchool the original continuity took place in, the 2018 ''WesternAnimation/DCSuperheroGirls'' is a true blue high school AU. Wonder Woman, Batgirl, Supergirl, Zatanna, and several other characters are high schoolers who are also superheroes (and supervillains) on the side.
* ''WesternAnimation/LittleShop'' is ''Film/TheLittleShopOfHorrors'' with Audrey and Seymour as teenagers.
* ''WesternAnimation/WingCommanderAcademy'' is an odd case -- adapting a [[Franchise/WingCommander video game series]] into a series where all the main characters from the games are cadets onboard the ''TCS Tiger's Claw'' would sound like a recipe for disaster. It's actually well-written and ''incredibly'' accurate to the games.

* ''Anime/PowerpuffGirlsZ'', an anime adaptation of ''WesternAnimation/ThePowerpuffGirls'', featured the girls as three unrelated typical 12 year-old middle schoolers that were given superpowers. It played like a {{Magical|Girl}}... 'scuse me, [[InsistentTerminology Scientific]] [[MagicalGirl Girl]] series.

* Craig Mc Cracken mocked the concept in ''WesternAnimation/ThePowerpuffGirls'', where the girls are ditzy morons more interested in shopping and boys rather than saving the town from destruction.

* Very similar to ''Isekai Quartet'' above, ''Anime/{{Kaginado}} uses the same premise of merging multiple franchises together and put them in the same high school without changing outfits. The franchises being ''Creator/KeyVisualArts''' ''VisualNovel/{{Kanon}}'', ''VisualNovel/{{Air}}'', ''VisualNovel/{{Clannad}}'', ''VisualNovel/LittleBusters'', ''VisualNovel/{{Rewrite}}'', and later ''Anime/AngelBeats''. However, only the actual high school characters attend Kagindo Academy, while all the other characters apparently live in the same town or live in their original homes, as evident with ''AIR''. Characters from the distant past are in the present, the series has no fear of spoiling its audience and it makes constantly fun of the TearJerker moments the franchises are known for.

* ''Anime/IsekaiQuartet'' is a 2019 {{Crossover}} series that is an ''official'' High School A.U. It brings together four LightNovel-based {{Isekai}} series published by Kodansha (''LightNovel/{{Konosuba}}, LightNovel/{{Overlord}}, LightNovel/SagaOfTanyaTheEvil, LightNovel/ReZero'') and puts them all in a single high school classroom.
