History Main / TheSevenMysteries

* In ''[[Anime/{{Doraemon}} The Doraemons Special]]'', Nobita and Matadora uses the seven mysteries to scare off two robbers from the school at night with the help of their gadgets.

* Mai's arrival at Fuuka Gakuen in ''Anime/MaiHiME'' quickly becomes one of that school's seven mysteries.

* In ''Manga/UruseiYatsura'', the teacher Onsen-Mark tries to do the traditional midsummer spook-the-youngsters-with-scary-stories routine and mentions the Seven Mysteries of Tomobiki High. Unfortunately, due to the {{weirdness magnet}}s in the class (Moroboshi and Co.), most of these were already the subject of various previous chapters, and the class was bored.
* The girls in ''LightNovel/StrawberryPanic'' do a similar investigation.
* All seven appear to be real as several important plot points in ''Manga/ToiletBoundHanakoKun'', with the titular character Hanako being the 7th Mystery. In their world, the 7 School Mysteries refer to a league of supernatural beings who try to keep balance in the school, including helping humans who may be harmed by other supernaturals. Hanako happens to be the leader of these beings.
* Came up in ''Manga/{{Mahoromatic}}'', with the added twist there actually ''was'' a [[http://www.mania.com/10-ghost-story-anime-episodes_article_126092.html ghost]] in a classroom.
* ''Manga/TheKindaichiCaseFiles'' story "Smoke and Mirrors" has "The Seven Mysteries of Fudo High." They all turn out to be [[spoiler: rumors started to cover up dead bodies hidden in an old building that used to be a lab for a crooked pharmaceutics company. Not to mention there were originally ''six'' mysteries.]]
* Mai's arrival at Fuuka Gakuen in ''Anime/MaiHiME'' quickly becomes one of that school's seven mysteries.
* Appeared in the later seasons of ''Manga/RanmaOneHalf'', revolving around a "lost school store" and its aged keeper, "the Secret Don of Furinkan High" whose stories of the school's past tied into the Warring States era, WWII, the Mongol Empire, and the Napoleonic Wars (and were, of course, pure fabrication). A later episode introduced an actual ghost girl to haunt the place.
* In ''Manga/MythicalDetectiveLokiRagnarok'', the girl sidekick takes Loki to her school to show him their seven mysteries. As usual, only the last one lacks a mundane explation.
* In the Creator/ToeiAnimation version of ''VisualNovel/{{Kanon}}'', after discovering Mai fighting demons at the school, Yuuichi asks Kaori if she's heard of a girl that appears at night. Kaori thinks he's talking about the obligatory "cute girl ghost" of the seven mysteries. However, every single one is completely bogus, including the ghost; Mai's supernatural connections have a very different origin.
* One of TheSevenMysteries is the main cause of plot in ''Anime/UtaKata''. The rest don't show up.
* ''Anime/DirtyPairFlash'' manages to set up a HighSchoolAU situation in its second season as an excuse for this plot. It turned out to be a ShaggyDogStory ''and'' a ScoobyDooHoax as the school was part of a planetwide amusement park and the "ghosts" were AllPartOfTheShow.

* Ikki's school in ''Manga/AirGear'' has seven mysteries, most of which are explained by the presence of a secret room Kogarasumaru eventually uses as their home base.

* ''Manga/HiganbanaNoSakuYoruNi'' is all about a school's seven mysteries (and the creation of an eighth...), and, as such, has this entire subject as a DiscussedTrope.
* A major plot point ''Manga/DuskMaidenOfAmnesia''. The Paranormal Club believes that finding all seven mysteries will help them discover the secrets behind [[CuteGhostGirl Yuuko's]] murder. Much of the plot involves distinguishing between rumors or ghost stories and true mysteries.

* The first episode of ''Manga/HauntedJunction'' had the PowerTrio searching not just for the Seven Spots, but for the seven ghosts associated to them. HilarityEnsues.
* ''Nana Fushigi Gakuen'' actually used this as the title (literally, "Seven Mysteries High School") and featured a pair of ghostbusting schoolgirls. The staircase that has more steps going down than up was the BookEnds for the series.
* A series of omakes in the ''Manga/{{Bleach}}'' anime had Ichigo investigating seven unexplained phenomena in Karakura Town, which invariably turned out to be his friends dicking around.
* In ''Manga/MyMonsterSecret'', the Seven Mysteries are specifically named, but the protagonists quickly realize that ''they're'' the Mysteries; the "Afterschool Vampire" is the series' female lead [[FriendlyNeighborhoodVampire Youko Shiragami]], the "Dwarf of the Hallway" is ClassRepresentative Nagisa Aizawa (a doll-sized alien who pilots a MobileSuitHuman), etc. [[spoiler:However, eventually they realize that these legends have been around for years and thus must refer to the ''past'' generation -- for example, the "Afterschool Vampire" isn't Youko but rather her father Genjirou.]]
* In ''Manga/AttackOnTitanJuniorHigh'', we have the "Seven Mysteries of Titan Junior High". Armin apparently is knowledgeable about them. As it turns out, they are a prank created by the Survey Club's members to make the test of courage more fun, but the seventh mystery appears to be true, since the ghost girl mentioned by Erwin is actually [[spoiler: Frieda Reiss]], implied to be a senior before she becomes a ghost.
* Shows up during an episode of ''LightNovel/TheDevilIsAPartTimer'' as the characters are trying to find a way to get more magic. It turns out there's only six mysteries, since finding the seventh (allegedly) triggers a call on your cellphone which will cause you to disappear. Naturally, the heroes immediately ask:
** 1. How does anyone know what happens if you disappear as soon as you find out?
** 2. Why would a decades-old legend involve modern cell phones?
* Comes up between story arcs in ''Manga/BlueExorcist''. The mysteries range from strange noises coming from one specific toilet stall to a house that never seems to get closer as you walk toward it. In a subversion, all seven of them turn out to actually have supernatural origins, no matter how mundane they sound.
* In ''Manga/GeGeGenoKitaro'''s sixth iteration, Neko-Musume explains to Mana that schools are often places where Yokai haunt and that each school has their own Seven Mysteries, which Mana lists down: the art room design statue that cries blood, the laughing anatomical model, the running statue of Kinjirō Ninomiya, the Jinmenken that lives in the connecting corridor, the portrait of Beethoven that comes out and plays the piano, Hanako-san of the third floor's girl's bathroom and Yōsuke-kun of the second floor's boy's bathroom. Later after Yōsuke-kun was defeated by Neko-Musume for kidnapping the other five and stalking Hanako-san, Nurikabe became one of Mana's school's mysteries, due to his infatuation.
* In ''Manga/MyHeroAcademia'', before inheriting One for All, Midoriya mentions that All Might's Quirk is one of the seven great mysteries of the world. What the other six are is yet unknown.
* The light novel SpinOff of ''Manga/KaguyaSamaLoveIsWar'' deals with the seven mysteries of Shuchi'in Academy, with the seventh being that anyone who finds the other six will fall to their death. Due to a string of coincidences, Ishigami ends up encountering all six of the non-fatal ones. The final chapter of the book also revealed that all of them (including the death) have a mundane origin from an event 40 years prior.
* ''Manga/ToiletBoundHanakoKun'' has this trope in spades, with the seven mysteries of the school being like a league of supernaturals that try to keep a balance within the grounds. Hanako himself is the 7th Mystery and happens to be the leader of the group, though he easily admits that there may be a traitor within the group.
* In the anime adaptation ''Manga/MyNextLifeAsAVillainessAllRoutesLeadToDoom'', the PortalBook found in the school library is stated to be one of the school's seven mysteries.

* A mission late in ''VideoGame/CrisisCore'' has Zack seeking out the seven wonders of Nibelheim, all of which have mundane explanations, and gets him a reward for figuring out.
* The third ''VideoGame/MegaManStarForce'' game has "The Seven Wonders of Echo Ridge," despite there being only six, as mentioned by an NPC ''very'' late in the game, after no doubt having driven batty many players who thought to look for them all out of curiosity.

* In ''VideoGame/BlazBlueContinuumShift'', [[UsedToBeASweetKid Carl]]'s [[MultipleEndings Gag Reel]] has him recall the time he, Noel, Tsubaki and Makoto (who he was at the academy with) had him go through one of these because he was feeling homesick.

* There's an UsefulNotes/RPGMaker game called ''VideoGame/SevenMysteries'', though strangely it's only this trope for the first four chapters. The remaining three deal with the hero of chapter four trying to get to the bottom of everything. As it turns out, [[spoiler: a psychotic student had killed seven classmates over a two-week period, framing his last victim, a shy transfer student, for his crimes. The girl's angry ghost was haunting the school, tormenting people who wandered in at night with horrific hallucinations. The headmaster knew about the haunting, but to avoid shutting the school down he conspired with the murderer to kill off the victims/witnesses and stockpile the bodies in a hidden room.]]
* Subverted in ''VideoGame/FantasyLife'': the seventh mystery of Castele is that Castele has only six mysteries.
* These are mentioned in the "Table For Six" event in ''VideoGame/GranblueFantasy''. The mysteries involve the strangeness of the main crew, or called as The Grancypher's Seven Mysteries. One of them is what species Vyrn is and why there seems to be [[MesACrowd four Lamrettas]] (which is just her talking to herself while drunk). There's also the question of the vast number of characters who were high-ranking officers/knights in other islands and/or those who had been of royalty or noble blood in general.
* The Realm of Spirits in ''VideoGame/BlankDream'' is themed around this. In order to reach your destination, you have to track down and experience six of the seven mysteries; the place where the mirror is locked away is considered to be the seventh.
* Thors, the military AcademyOfAdventure featured in ''VideoGame/TheLegendOfHeroesTrailsOfColdSteel'', has a set of seven mysteries that your main character, Rean Schwarzer, can investigate in an optional quest. All of them turn out to be mundanities: a supposed graveyard that was really just a bad test paper a student buried "six feet under," a "haunted piano" that was really just being tuned, a supposed poltergeist that was just the result of frustrated cooks, etc. The twist is that there is apparently an entirely different second set of seven mysteries also taking place at the Academy that is only briefly alluded to. [[spoiler:When Rean asks why she doesn't count the ''definitely'' mysterious [[EldritchLocation Old Schoolhouse]] as one of the seven mysteries, Beryl, head of the Occult Research Society club, implies that of course it's included... in the ''real'' [[CrypticBackgroundReference seven mysteries of Thors]]... In ''Cold Steel II'', when the Reverie Corridor appears in the Old Schoolhouse, she tells Rean that he's fortunate to be one of the lucky few that gets to see the truth behind the 'eighth' of the academy's seven mysteries.]]
* One of the sidequests in ''VideoGame/PokemonUltraSunAndMoon'' is searching around a school for seven mysteries given to you by a schoolgirl. After finding the first six, the girl confessed that there’s no seventh mystery, but thanks you for taking your time to help out since these mysteries were scaring her classmates. [[spoiler:The girl is later gone. A faculty member reveals that she was actually the seventh mystery herself, being a ghost.]]
* In ''VideoGame/LittleWitchAcademiaChamberOfTime'', there are also 7 mysteries for Akko and her friend to explore. At least here, Luna Nova is a millenia-old school of magic, making the idea have a bit more merit. [[spoiler:In spite of the supernatural school, six of them end up having fairly mundane explanations. the 7th is the actual villain of the game.]]

* Played with in VisualNovel/HiganbanaNoSakuYoruNi, where the school it takes place in has seven mysteries in the form of horror stories that take the form of {{Youkai}}. Each Youkai hunt for human souls while following the rules of their mysteries. Unlike the mention above where there is usually six mysteries with the seventh mystery being "why is there seven", Higanbana somewhat inverts it by having the precedence for an ''Eighth'' Mystery in it's first story in the form of one of the protagonists, Marie.
* The whole plot of VisualNovel/MysteriousForumAndSevenRumors is centered around the titular [[ExactlyWhatItSaysOnTheTin seven rumors posted on a mysterious forum]].

** In ''VideoGame/KingdomHeartsII'', part of the extended prologue in Twilight Town features Roxas and his friends investigating "Seven Wonders" that appear to have mundane explanations, while the true explanations are quite extraordinary, the blanket explanation being that they're either glitches in the simulation or Nobodies screwing around with things on purpose... Well, except for the staircase one. Rai's an idiot.

* In ''[[Anime.MyNextLifeAsAVillainessAllRoutesLeadToDoom My Next Life as a Villainess]]'', the PortalBook found in the school library is stated to be one of the school's seven mysteries.

* In the VideoGame for ''Anime/LittleWitchAcademia'', there are also 7 mysteries for Akko and her friend to explore. At least here, Luna Nova is a millenia-old school of magic, making the idea have a bit more merit. [[spoiler:In spite of the supernatural school, six of them end up having fairly mundane explanations. the 7th is the actual villain of the game.]]

* All seven appear to be real as several important plot points in ''Manga/{{Jibaku Shounen Hanako Kun}}'', with the titular character Hanako being the 7th Mystery. In their world, the 7 School Mysteries refer to a league of supernatural beings who try to keep balance in the school, including helping humans who may be harmed by other supernaturals. Hanako happens to be the leader of these beings.

* There's an VideoGame/RPGMaker game called ''VideoGame/SevenMysteries'', though strangely it's only this trope for the first four chapters.

The headmaster knew about the haunting, but to avoid shutting the school down he conspired with the murderer to kill off the victims/witnesses and stockpile the bodies in a hidden room.]]

* All seven appear to be real so far as several important plot points in ''Manga/{{Jibaku Shounen Hanako Kun}}'', with the main supernatural Hanako being the 7th and their leader. In their world, the 7 School Mysteries refer to a league of supernatural beings who try to keep balance in the school, including helping humans who may be harmed by other supernaturals. Without his involvement as a 7th Mystery and his sympathy toward humans, Hanako may not have helped Yashiro Nene as much as he's done.

* In ''Manga/GeGeGenoKitaro'''s sixth iteration, Neko-Musume explains to Mana that schools are often places where Yokai haunt and that each school has their own Seven Mysteries, which Mana lists down: the art room design statue that cries blood, the laughing anatomical model, the running statue of Kinjirō Ninomiya, the Jinmenken that lives in the connecting corridor, the portrait of Beethoven that comes out an plays the piano, Hanako-san of the third floor's girl's bathroom and Yōsuke-kun of the second floor's boy's bathroom. Later after Yōsuke-kun was defeated by Neko-Musume for kidnapping the other five and stalking Hanako-san, Nurikabe became one of Mana's school's mysteries, due to his infatuation.

* In Manga/MyHeroAcademia, prior to inheriting One for All, Izuku mentions that All Might's Quirk is one of the seven great mysteries of the world. What the other six are is yet unknown.

Especially common in a Japanese school setting, these tend to be awkwardly brought up during [[FestivalEpisode summer episodes]], where mysterious legends are attributed to a not-particularly-old place. Nearly always end up being complete horsehockey, except for perhaps the last one. Common themes include voices in an empty room, faces in a wall, staircases with more steps going up than coming down, and other variously spooky and paranormal things.

* In ''VideoGame/{{Yakuza}} 3'', a series of subquests in Downtown Ryuugi centers around 'The Seven Mysteries of Ryuugi', as told by a group of gossiping schoolgirls. Inevitably, each of the mysteries turn out to either have a mundane explanation, or - more frequently - comes down to somebody running a scam. For the perfect punchline, the main character himself essentially turns into the Seventh Mystery - a '[[CoolOldGuy ripped older guy]]' who shows up when people fall prey to loansharks or scammers to beat them up. Considering how [[MadeOfIron invincibly badass]] Kazuma Kiryuu is, he's certainly closer to being supernatural than any of the other so-called mysteries...

* There's an RPGMaker game called ''VideoGame/SevenMysteries'', though strangely it's only this trope for the first four chapters. The remaining three deal with the hero of chapter four trying to get to the bottom of everything. As it turns out, [[spoiler: a psychotic student had killed seven classmates over a two-week period, framing his last victim, a shy transfer student, for his crimes.
