By mistake or some odd chain of events, an OrdinaryHighSchoolStudent winds up attending an ExtranormalInstitute. Perhaps they're a human in an AllGhoulsSchool, or a {{muggle|s}} in a WizardingSchool, but whichever it is, [[FishOutOfWater they clearly don't fit in]]. If the {{masquerade}} is in full effect, they'll probably have to try to blend in with the ''usual'' type of student, with the consequence of failure ranging from LaserGuidedAmnesia to CruelAndUnusualDeath [[KilledToUpholdTheMasquerade to uphold the masquerade]].

Acts as a NaiveNewcomer. [[LevelGrinding After sufficient experience]], they may [[TookALevelInBadass upgrade]] to [[EmpoweredBadassNormal something]] that ''does'' fit in.

!!Examples:

[[AC:{{Anime}} and {{Manga}}]]
* ''Manga/{{Mx0}}'': After failing to sneak ''into'' (unknown to him) a secret WizardingSchool, Taiga gets dragged though the school's barrier by a teacher mistaking him for a student trying to sneak ''out''. A sequence of unlikely events establishes him as a genius mage when he actually has no power at all--a reputation he is forced to uphold thereafter.
* ''Manga/RosarioToVampire'': Tsukune accidentally gets accepted to AllGhoulsSchool in AnotherDimension and faces the death penalty for spying if discovered. [[spoiler:Turns out the BigBad of the second major arc is himself a [[EmpoweredBadassNormal former human]] who ended up at Youkai Academy under the same circumstances. And in both cases, their acceptance to the school wasn't an accident at all.]]
* ''Manga/AnimalAcademy'' / ''Manga/HakobuneHakusho'': A BookDumb girl is mistakenly accepted to a school for animal shapeshifters and begs her way in (still not knowing what the school was) when the head faculty see that she's human because no other school will take her. The other students believe she's a cat, because her given name is--quite conveniently (and probably why she was first accepted)--''[[SpeciesSurname Neko]]''.
* ''LightNovel/{{Kanokon}}'' is a borderline case, since the school is dedicated to rehabilitate youkai who have trouble integrating into human society, but at least some unwitting humans attend as well to provide an incentive to be more stealthy about their true natures.
* ''Manga/HollowFields'': Lucy Snow is a fairly ordinary child in a school for the children of [[MadScientist mad scientists]].
* ''Manga/AfterschoolCharisma'': Shiro's the only non-clone in a school for clones. [[spoiler:Or Is He?]]
* ''Manga/SayonaraZetsubouSensei'': Nami Hitou, the normal girl in a DysfunctionJunction class.
** Ironically, she develops a complex about it, making her NotSoAboveItAll.
* ''Manga/OuranHighSchoolHostClub'' is a non-supernatural example: Haruhi is a working-class girl at a school for the [[ArbitrarilyLargeBankAccount comically rich]].
** And unusual in that as the story starts, she's ''already'' attending and has blended in so well that nobody's really noticed her yet.
* ''{{Anime/Pokemon}}'': Jessie apparently attended one of these prior to joining Team Rocket - she wanted to become a Pokémon nurse, but somehow wound up at a school training Chanseys as medical assistants.

[[AC:{{Comics}}]]
* Angela, the protagonist of ''[[ComicBook/{{Underburbs}} The Underburbs]]'' and her admirer, George, for entirely different reasons. (Angela has actually gotten turned into a witch by the time she enrolls a short time before.)
* The strip ''[[GrangeHill Strange Hill]]'' in ''TheBeezer'' was a variation--an ordinary ''teacher'' stuck in a horror-themed school. On one occasion he was delighted when an apparently normal boy joined his class, but he turned out to be a MadScientist.
* In ''ComicBook/AllGhoulsSchool'', Becca Norman is suspended for cheating at her old school. Her only chance to pass is to attend summer school at the Darkmoor Academy boarding school. What she does not know is that darkmoor is an AllGhoulsSchool and her attendence there has been carefully orchestrated.
* Tyler Marlocke of ''ComicBook/{{PS238}}'' - normal, unpowered child in a school for superkids. He doesn't pretend to be anything else, but between the fact that both his parents are legendary superheroes and the school being a constant WeirdnessMagnet, he has no choice but to become an ActionSurvivor in order to, well, survive. Currently in training to become BadassNormal.

[[AC:FanFiction]]
* ''WesternAnimation/{{Detentionaire}}'' fan fic "FanFic/StrangerInAStrangeSchool" uses this exact trope as a title but for the most part it has to do with the main character, an OC, being a new student at A. Nigma.
* ''FanFic/TheMysteriousSchool'', as its name suggests, is all about four students who get accepted into a school... [[ExtranormalInstitute for people with magic.]]

[[AC:{{Film}}]]
* The protagonist of ''Film/SkyHigh'' is a regular boy who gets sent to a SuperheroSchool despite having no powers.

[[AC:{{Literature}}]]
* The entire plot of ''Literature/VampireHigh'' is that Cody, as a newcomer to a small town in Massachusetts, is one of the few people unaware that there are vampires living there as well. As a result, he has no idea that the high school he attends is primarily intended for vampires (there are a few humans, but all are there through necessity and not choice).
* Inverted in ''Literature/HOWLHigh'' - the protagonist is a half-warlock who attends a high school dedicated to Hollywood horror effects. Also played with in that the "normals" attending the school with him are weird enough to shake a guy with ''actual'' monsters in his family.

[[AC:VisualNovel]]
* The heroine of ''VisualNovel/HatofulBoyfriend'' is a human teenager attending a prestigious private high school for birds. Going by the official manga, it's also a ''boys' school''. Added to that is the fact that she is a hunter-gatherer who lives in a cave.

[[AC:{{Web Comics}}]]
* A-san of ''OverlordAcademy'' is an accidentally transferred into the titular school. He's [[ButtMonkey an oboist]].
* Graham in ''Webcomic/WizardSchool'' is a rich, drunken jerk who replaces the "Chosen One" at a school for wizards.
* Cameron of ''Webcomic/{{Zoophobia}}'' is the Zoo-Phoenix Academy's new guidance counsellor, and happens to be the only [[spoiler: fully]] human staff member.

[[AC:{{Western Animation}}]]
* ''WesternAnimation/MyGymPartnersAMonkey'' is about a human boy accidentally sent to an animal school.
* ''[[TheComicStrip Mini Monsters]]'' (aka ''Camp Mini-Mon'') had two normal kids accidentally be sent to a SummerCamp for MovieMonsters' ({{Dracula}}, FrankensteinsMonster, etc.) kids.
* Similarly, ''WesternAnimation/GravedaleHigh'' featured Creator/RickMoranis as the only human ''teacher'' at an AllGhoulsSchool.
* In ''WesternAnimation/TheMagicSchoolBus'', Phoebe seems to be this trope. Her CatchPhrase is "This never happened at my old school!" while several of the other kids seem much more accustomed to the strange things Ms. Frizzle does.
** Eventually, Phoebe does seem to acclimate to the strangeness and finds her own niche, leading to the addition of Arnold's cousin Janet to the show as the new outsider.
* ''WesternAnimation/GalaxyHigh'' is about two normal teenagers who become the first Earthling students at the eponymous school for aliens.
* ''WesternAnimation/ScoobyDooAndTheGhoulSchool'' is a Scooby Doo movie about Scooby, Shaggy, and Scrappy becoming teachers at an ExtranormalInstitute full of {{Cute Monster Girl}}s. They are the only human staff members.
* ''WesternAnimation/OverTheGardenWall'' has an episode where Wirt, Gregory, and Beatrice run into a schoolhouse of well-dressed animals.
