History Main / TheSevenMysteries

There are several re-occurring ones based off of ghost stories created by successive generations of school kids.

[[folder:Anime and Manga]]

* 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.

* PlayedForLaughs in ''Manga/JoJosBizarreAdventure: Stone Ocean'' with the Seven Mysteries of Green Dolphin Prison. They don't relate to any of the prison's ''actual'' mysteries, they're just a tongue-in-cheek way the inmates can complain about the workings of the prison. One of these mysteries is how, even though there should be a meal for every inmate, there'll be none left for anyone who arrives last; immediately afterwards, it's demonstrated this is because some inmates will take more than one meal. Because this part is set in Florida, the Seven Mysteries are localized in English as the Seven Wonders.

* 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.

* ''Manga/TheUnforgivingFlowersBlossomInTheDeadOfNight'' is all about a school's seven mysteries (and the creation of an eighth...), and, as such, has this entire subject as a DiscussedTrope.

[[folder:Literature]]
* Shows up during in ''Literature/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?
* The girls in ''Literature/StrawberryPanic'' do a similar investigation.
* ''Literature/StudentCouncilsDiscretion'': The students confuse this with a scary story tournament, so the school ends up with dozens of mysteries, all horrifying. Minatsu undoes it all by adding the legend of the girl who goes around destroying all the ghosts. But Ken's story is the scariest:
--> '''Ken''': Once upon a time there was a little maid called Kurimu who served her master with all her heart and all her body and all her soul. The end.\\
'''Kurimu''': NOOOOO!

* Subverted in ''VideoGame/FantasyLife'': the seventh mystery of Castele is that Castele has only six mysteries.

* ''VideoGame/TwilightSyndrome'' has these in the aptly-named "Hinashiro High School's Seven Mysteries" chapter which involves investigating six of them, [[ArsonMurderAndJaywalking since the fourth one was a rumor that two of the male teachers were in a secret relationship]]. Pretty much all of them turn out to be mundane, such as a statue bust rumoured to cry tears of blood because of a human skull embedded in it was actually a novelty money box, ghosts talking in the library at first [[BrickJoke appears to be two male teachers in a secret relationship]], but they're actually holding a mahjong party with the other teachers after hours, with the prior conversation actually being them being afraid they'll get caught holding these parties. Eventually the main trio get pissed and are about to head home, only to investigate the remaining one about a phantom runner on the track. [[spoiler:It's a LivingStatue of Ninomiya Sontoku who just sprints away, which the girls are a bit startled by, but ignore it [[INeedAFreakingDrink and just go get ramen]].]]

* Played with in ''Manga/TheUnforgivingFlowersBlossomInTheDeadOfNight'', 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.

* Shows up during an episode of ''LightNovel/TheDevilIsAPartTimer'' as the characters are trying to find a way to get more magic.

** 2. Why would a decades-old legend involve modern cell phones?
* ''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.

--> '''Ken''': Once upon a time there was a little maid called Kurimu who served her master with all her heart and all her body and all her soul. The end.\\
'''Kurimu''': NOOOOO!

* Apparently, the Seven Mysteries of North High are the subject for ''[[LightNovel/HaruhiSuzumiya Suzumiya Haruhi no Chokuretsu]]'', a game released for the DS in Japan.

* 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.

* PlayedForLaughs in ''Manga/JoJosBizarreAdventure: Stone Ocean'' with the Seven Mysteries of Green Dolphin Prison. They don't relate to any of the prison's ''actual'' mysteries, they're just a tongue-in-cheek way the inmates can complain about the workings of the prison. One of these mysteries is how, even though there should be a meal for every inmate, there'll be none left for anyone who arrives last; immediately afterwards, it's demonstrated this is because some inmates will take more than one meal.

* There are Seven Mysteries within Green Dolphin '''Prison''' in ''Manga/JoJosBizarreAdventure: Stone Ocean'' (which is actually set in Florida, not Japan) - one of them being the unusual and rare appearance of Louis Vuitton bags at the prison shop - however, they don't appear to have anything to do with the plot and are the ''least'' mysterious things about the dangerous prison.

* ''Twilight Syndrome'' has these in the aptly-named "Hinashiro High School's Seven Mysteries" chapter which involves investigating six of them, [[ArsonMurderAndJaywalking since the fourth one was a rumor that two of the male teachers were in a secret relationship]]. Pretty much all of them turn out to be mundane, such as a statue bust rumoured to cry tears of blood because of a human skull embedded in it turned out to be a novelty money box, ghosts talking in the library at first [[BrickJoke turn out to be two male teachers in a relationship]], but they're actually holding a mahjong party with the other teachers after hours. Eventually the main trio get pissed and are about to head home, only to investigate the remaining one about a phantom runner on the track. [[spoiler:It's a LivingStatue of Ninomiya Sontoku, which the girls [[UnusuallyUninterestingSight hardly bat an eye to]] and just go get ramen.]]

* 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.

There a common sight in anime, visual novels and other works from Japan.

* Legends about ghosts playing Moonlight Sonata after hours. Sometimes its played by no one, but often if its visible the ghost looks like Beethoven.
* There are several of common ones revolving around statues of coming to life in some fashion
** Kinjirō Ninomiya, a famous scholar & common subject of statues (espcially in front of japanese schools) is a common one of these. He's often seen running.

* One episode of ''Manga/MariaHolic'' focuses on the seven mysteries of Ame no Kisaki Girls' School, a high percentage of them involving [[{{Nosebleed}} blood]]. To the surprise of no one, [[SchoolgirlLesbians Kanako]] is directly responsible for all of them due to her [[ImagineSpot fantasies]]. Kanako's homeroom teacher later tells her that the seven mysteries applying to the whole school change every year, but seven ''other'' mysteries about Kanako's dorm manager have never changed; they range from the genuinely mysterious ("[[OlderThanTheyLook what the hell is her real age?]]") to mundane FridgeLogic ("why are Virtual Boys not banned along with the other electronics?"). If anyone happens to learn all seven mysteries, the dorm manager will do...[[NoodleIncident well, something, anyway]].
