The universe(s) of the writings of TYPE-MOON's scenario director, Kinoko Nasu. It's made up of several "sub-universes" ("franchises" that [[CharacterOverlap share characters]]) that share most (but not all) details between each other. Also of note is that the franchises themselves often include several [[AlternateUniverse alternate continuities]], since the primary works are visual novels with [[MultipleEndings multiple and]] ''[[MultipleEndings very]]'' [[MultipleEndings mutually exclusive paths]].

Several of the main works are [[HGame H-games]] (a.k.a. ''eroge'', marked as such), but many of the related works are not.

'''Notes (OurAngelsAreDifferent)'''
* Also called ''Literature/AngelNotes''; it's a short story featuring an apocalyptic future where [[EldritchAbomination The Ultimate Ones]] invade the planet and destroy the remains of humanity after the [[GaiasVengeance death of Gaia]]. Also notable for providing the foundation for some concepts in the 'verse, namely that "Gaia" is a living being and that each planet has an "Ultimate One".

'''''LightNovel/KaraNoKyoukai'' - the Garden of Sinners (OurSoulsAreDifferent)'''
* Protagonist Shiki Ryougi wakes up from a coma and finds that although she retains her memories, she cannot identify with them as her own. As she struggles through her own life like a stranger, strange events (such as suicides and murders) begin to happen around town.
* Three novels, divided into seven chapters and an epilogue. A series of seven animated feature-length films aired in theaters from late 2007 to 2009. The DVD editions for all movies are available as of December 2009, and the Blu-Ray editions (incidentally with ''English'' subtitles) were released in February 2011, together with an OVA of the epilogue.
* ''Mirai Fukuin: recalled out summer'', a bonus chapter released ten years after the original series. An animated adaptation was also released.
* Being one of the first works written, this is the one work officially claimed to take place in an AlternateUniverse from the rest (due to major discrepancies, such as Shiki's eyes and Touko's goal). Most of the characters here can be considered the 'blueprints' for those in the rest of the 'verse. Every character from the other works are still present in ''[=KnK's=]'' universe ([[ForWantOfANail with the exception of anyone True Ancestor-related]]) and vice-versa, but they are ''slightly'' different, given the conflicting aspects of each universe having possibly changed their circumstances--excluding [[CoolOldGuy Zelretch]], who can pop into any given universe at a whim. Shiki is included as a Character in ''VideoGame/MeltyBlood: Actress Again'' after getting pulled across dimensions, thus indicating that ''Kara no Kyoukai'' and ''Melty Blood'', at least, are [[AlternateContinuity Alternate Continuities]].

'''''VisualNovel/MahouTsukaiNoYoru'' - Witch on the Holy Night'''
* Originally an unpublished novel; it details the past of Aoko Aozaki (the minor but important character in ''VisualNovel/{{Tsukihime}}'') and her mentor, Alice Kuonji. They meet Shizuki Soujuurou, a man unfamiliar with city life. A VisualNovel adaptation was released (after a ''very long'' wait) on April 12, 2012. It is also TYPE-MOON's first all-ages visual novel.
* Two sequels have been planned, but they may not appear for some time.

'''''VisualNovel/{{Tsukihime}}'' (OurVampiresAreDifferent)'''
* ''VisualNovel/{{Tsukihime}}'', an eroge visual novel. Features TheVerse's ''[[NamesTheSame other]]'' Shiki, Shiki Tohno, going back to his old family mansion after he was kicked out at eight years old. He suffered a childhood accident which granted his eyes [[MagicalEye strange abilities]], and his own past is rather muddled, as well. Has a manga and an [[VisualNovel/{{Tsukihime}} anime adaption]], complete with BleachedUnderpants[[note]]The anime and manga adaptations of ''Tsukihime'' are the only Nasuverse adaptations to retain the love scene between the story's couple -in this case between Shiki and Arcuied- instead just toning it down to non-pornographic levels[[/note]].
* ''Tsukihime PLUS+DISC'', a visual novel. A "fun disc" with a new short story (introducing two new characters, and finally revealing protagonist Tohno Shiki's face) and several other shorts discussing the 'verse. Also, sequel promotion.
* ''Kagetsu Tohya'', an eroge visual novel. Yet another "fun disc" sequel that doesn't specifically take place in any one particular ending of the original game. In any case, about 90% of it is a (very messed up) dream.
* ''VideoGame/MeltyBlood'', a fighting game. Relatively story-heavy for its genre. Has several sequels, itself, some of them expanding the story considerably, mostly the update ''Melty Blood Re-Act''. Supposedly takes place after an unreleased story route in ''Tsukihime''.
* ''Tsukihime 2 / the dark six'', currently a running joke. A brief trailer is in ''Kagetsu Tohya'', and there have been many short stories that expanded the characters (especially Tohno Shiki) far beyond their original roles.
* A remake of the original ''Tsukihime'' was announced in April 2008, reportedly finally including the Yumizuka Satsuki route that has been [[RunningJoke one of the running jokes of the franchise]]. Currently in DevelopmentHell, though it has been indicated that they're still working on it.
* ''Manga/HanaNoMiyako'', a manga that follows Miyako Arima while she studies in a school where students are ranked by martial arts fights.

'''Fate ([[FunctionalMagic Our Magics Are Different]])'''
* ''VisualNovel/FateStayNight'', an eroge visual novel. Shirou Emiya, Mage-in-self-training, stumbles into the "Holy Grail War". Has a manga, an anime adaption and movie by Creator/StudioDEEN, [[Anime/FateStayNightUnlimitedBladeWorks another anime adaptation]] by Creator/{{ufotable}}, and a [=PlayStation=] 2 port, all with the aforementioned bleached underpants.
* ''[[Manga/FateKaleidLinerPrismaIllya Fate/kaleid liner PRISMA ILLYA]]'': A manga that features an AlternateUniverse storyline with Illyasviel (the resident EnfanteTerrible) as the main character... and as a MagicalGirl, complete with a spunky talking staff called Ruby. It is very much an AffectionateParody, both of ''Fate/stay night'' and MagicalGirlTropes in general.
* ''LightNovel/FateZero'': A prequel novel (and later, an anime adaptation by ufotable) that covers the events of Heaven's Feel IV, [[WhenItAllBegan the fallout from which affected every character]] in ''Fate/stay night''. Note that ''Fate/Zero'' assumes that you have read ''Fate/stay night'', so beware of spoilers.
* ''VisualNovel/FateHollowAtaraxia'': A sequel/[[{{Doujinshi}} fan-disc]] Visual Novel that was released in 2005. A [[LighterAndSofter more lighthearted story]] set six months after the conclusion of Heaven's Feel V, it focuses on a magus called Bazett Fraga [=McRemitz=], who finds herself trapped in a strange GroundhogDayLoop with a mysterious Servant called "Avenger".
* ''LightNovel/FateApocrypha'': A light novel by Yuichiro Higashide that centers on a version of Heaven's Feel with fourteen Servants sorted into two teams of seven. An AlternateUniverse that diverges during the Third War. The project was originally pitched as an MMORPG, but it never took off.
* ''Anime/FatePrototype'': A twelve-minute {{OVA}} included in the final volume of ''Anime/CarnivalPhantasm''. It is based on the first draft of ''Fate/stay night'' written by Kinoko Nasu in his high-school days, when it was intended as a traditional novel instead of a Visual Novel. Currently has a series of {{Prequel}} {{Light Novel}}s in the works, ''Fate/Prototype: Pale Silver Fragments''.
* ''Literature/FateStrangeFake'': A proposed novella by [[LightNovel/{{Baccano}} Ryohgo Narita]] that focuses on a knock-off version of Heaven's Feel taking place in California, ten years after ''Fate/hollow ataraxia''. According to the release, it was a cancelled project meant to introduce the setting of a potential role-playing game, but considering it was published on AprilFoolsDay in 2008, the question of whether it was ever a serious project remains unanswered. Certain elements have been reused in other works, leaving its canonicity up in the air. It was greenlit as a full Light Novel series.
%%Leave the redlink where it is.
* ''[[Podcast/FateStayTune Fate/stay tune]]'' was an internet radio show that was broadcast while the {{anime}} was on the air, hosted by Creator/AyakoKawasumi (Saber) and Creator/KanaUeda (Rin). A sequel show, "[[GratuitousEnglish Fate/stay tune: Unlimited Radio Works]]" was broadcast for the "Unlimited Blade Works" movie, hosted by Creator/JunichiSuwabe (Archer) and the aforementioned hosts.
* ''[[VideoGame/FateTigerColosseum Fate/tiger colosseum]]'', a PSP exclusive 3D brawler, which serves as both a [[ThirdOptionAdaptation sequel]] and [[AffectionateParody parody]] of the original games. Taiga Fujimura initiates a war for the Tiger Grail and the Masters and Servants compete for it once more. Followed by a stand-alone expansion pack, ''Fate/tiger colosseum UPPER'', which added more playable characters from ''hollow ataraxia'' and ''zero'', as well as Arcueid, Kohaku (both in MagicalGirl form), and Neco-Arc, making it the first real {{Crossover}} between ''Fate'' and ''Tsukihime''.
* ''VideoGame/FateUnlimitedCodes'', a fighting game. Follows the general plot of ''Fate/stay night'' but proceeds into a different direction; "What if this character were the protagonist?". Also includes Luviagelita Edelfelt from ''Fate/hollow ataraxia'', a surprise entry of Lancer from ''Fate/Zero'', and Saber Alter from the Heaven's Feel route, as well as a "new" entry of "Saber Lily", an apparently "Bright" version of Saber to round off the trifecta.
* ''VideoGame/FateExtra'', an alternate universe setting with a new Holy Grail War, released for the PSP in July of 2010. Differs from the rest of the series in that the player can choose their character's gender and Servant (from Saber, Caster, or Archer). Has a sequel in the form of ''Fate/EXTRA CCC''.
* ''VideoGame/FateGrandOrder'', the "Fate Online Project Reboot" RPG in iOS and Android based off of the scrapped ''Fate/Apocrypha'' online game.

* A series of light novels written by Meteor Hoshizora that details the adventures of Homura Hinooka, a new first class Investigator with the title of "Magician", as she and the members of her school's Explorations Club explore a vast, uncharted planet known as ''Imaginary Earth''. The series has three volumes split into two parts each, with Parts 1 detailing Homura's school life, and with Parts 2 detailing her adventures on Imaginary Earth. May or may not have anything to do with the [[Franchise/TheNasuverse Nasuverse]].

'''LightNovel/{{DDD}} aka ''Decoration Disorder Disconnection''. (OurDemonsAreDifferent)'''
* A series of novels that are not directly connected, but explore another new aspect of TheVerse: demons (not oni and oni hybrids like in ''Tsukihime''; true demons).

'''''Anime/CarnivalPhantasm (SomethingCompletelyDifferent)'''''
* An official TYPE-MOON crossover manga adapted into anime in {{Summer 2011|Anime}}. It's a crossover between ''Fate/stay night'' and ''Tsukihime'', focusing more on [[GagSeries random and hyper crossover madness]] rather than a serious crossover between the series.

* The second official TYPE-MOON crossover manga by artist B-suke, where all of the TYPE-MOON characters, including those in {{Alternate Universe}}s, meet at the Ahnenerbe Cafe.

* This series strays far from most other TYPE-MOON franchises in that instead of revolving around magic, mages, and the supernatural, it revolves around terrorism and biological weaponry. It's the only TYPE-MOON franchise featuring characters who fight using guns, as opposed to the usual bladed weapons.
** Although this series was created by TYPE-MOON co-founders Kinoko Nasu and Takashi Takeuchi, it is possibly not part of the Nasuverse proper due to its status as a SpinOff to an unrelated VisualNovel.

* A short story by Nasu written for Creator/MaayaSakamoto's Full Moon Recital and later adapted in a manga by Sasaki Shonen, of the ''Tsukihime'' manga fame. It follows a girl whose grandmother claims to come from the Moon. It is passed in a world where people started colonies in the Moon, but soon lost interest, resulting in them giving up on living.

'''''[[DevelopmentHell Girls Work]]'''''
* Notable for ''not'' being done by Kinoko Nasu and Takashi Takeuchi, despite being a TYPE-MOON production. The story reportedly is about supernatural happenings in Shinjuku. The title was announced in 2008 as a Visual Novel, and then in December 2010 it was reported that it would be released as an anime instead. [[{{Vaporware}} Since then, nothing has been heard about it]].

[[TheWikiRule Has its own wiki]] [[ here]].

The Nasuverse is mostly unified in its rules on FunctionalMagic and related topics (like non-human species). Though crossovers are rare, they ''do'' happen, even if in incredibly roundabout ways.

Then again, as already stated, it isn't internally consistent because large portions of the source material are mutually exclusive, and some parts of it are obviously not canon to begin with (self-parodies, etc.); the canon universe is more about characters and the interaction between them, and less about the actual plot(s) taking place. {{Doujinshi}} authors take full advantage of this, and the amount of fan material available is staggering. Many works might not even be truly set in the same 'verse.

Due to the sheer amount of rules and terminologies involved within the Nasuverse, there is now an [[Analysis/{{Nasuverse}} analysis page]] as a guide to wade through them, also serving as a dissection of the setting through tropes. Please feel free to contribute. Also now has a [[Memes/{{Nasuverse}} memes page]].

'''Pastimes of Nasuverse fans (sometimes called "Type-Lunatics", even by themselves) include:'''
* Discussing [[MyKungFuIsStrongerThanYours power levels]] inside and across franchises. Of particular note, the WordOfGod strongest being, Type-Mercury/ORT, has become a loved and hated icon of the Nasuverse.
* Arguing over whether either Shiki (mainly [[VisualNovel/{{Tsukihime}} Shiki Tohno]]) can kill [[VisualNovel/FateStayNight Servants]], or [[CosmicHorror other beings]] for that matter (Word of God be [[DeathOfTheAuthor damned]]).
* [[GirlsLove Pairing off the numerous female (due to its eroge roots) characters]] with each other. Far easier in ''Fate'' than in ''Tsukihime'', unless you're a FoeYay or {{Twincest}} kind of person.
* Hating the ''Tsukihime'' anime adaptation, mostly citing low budget, character wrecking, vague storytelling, and OOC actions that just don't make sense when one has read the visual novel, and loving the manga adaptation. They even claim that the anime ''doesn't exist''.
* Making fun of the pornographic aspects in the games, [[FanDisservice considering it hilariously bad]], particularly [[UnusualEuphemism the metaphors used for the sex organs]].
* Arguing about the intelligence/stupidity levels of the protagonists (a ''very'' [[SeriousBusiness touchy]] [[BrokenBase topic]] - one end of the spectrum has them as subtle geniuses, the other sees them as having noticeable cases of Down Syndrome), [[VisualNovel/FateStayNight Shirou Emiya]] being the most common focus.
* Figuring out scenarios based on the [[ ridiculously convoluted character relationships]] [[ (enlarged)]]. Even '''that''' chart only ''slightly'' helps (though it doesn't include the characters from Fate/Zero, and does not show most of the relationships, especially Shirou's or Shiki's relationships with most of the heroines, correctly; for instance, missing out Shirou's love for Sakura and Rin, even though their routes are just as canon as Saber's).
* Making a [[ gigantic tabletop roleplaying game based on the Nasuverse]].
