History Defictionalization / AnimeAndManga

* In the "Mother's Rosario" arc of ''LightNovel/SwordArtOnline'', Kirito invents a "Bi-directional Probe" to give Yuuki, an ''Alfheim Online'' player confined to a hospital due to AIDS, a chance to experience life in the real world. Similar technology has been invented since that gives ill people a chance to experience life beyond the confines of their sterile environments, with one of the most prominent examples being for [[WebVideo/VShojo Ironmouse]], a chronically-ill and physically-disabled VirtualYoutuber, who was able to attend an anime convention with her friend WebVideo/CDawgVA, via [[https://www.youtube.com/watch?v=_acUGF-b8Cw a specially-constructed remote-controlled drone]].
* ''Space Travelers: The Animation'' [[note]]not related to the re-branded version of ''Film/{{Marooned}}'' seen on ''Series/MysteryScienceTheater3000''[[/note]] was produced as a spinoff for a live action caper comedy also called ''Space Travelers''. The gimmick was that it was the ShowWithinAShow that inspired one of the main characters of the live action film, a wannabe bank robber, to talk his partners in crime, and the hostages in the bank who quickly suffered StockholmSyndrome, to adopt the personas of the show's characters while negotiating with the cops, so everyone starts to [[BecomingTheMask Become Their Mask]] while planning to escape. Creator/MediaBlasters licenced the anime movie, but without the tie-in to the live-action movie, or any reference to it, all they had was a SciFi ClicheStorm and a cast of awesome names.

* The Sakuma Drop candy in ''Anime/GraveOfTheFireflies'', which was Setsuko's [[TrademarkFavoriteFood favorite snack]], actually [[InvertedTrope existed in real life]] before the anime was made. An exact replica can from the anime was released in 1988 and reprinted in 2008. That said, it's [[MoodWhiplash outright jarring]] to see Setsuko printed on the can, considering '''[[MisaimedMarketing how it was used in the end]]'''.

* Racing anime ''Anime/HighspeedEtoile'' [[https://www.thecheckeredflag.co.uk/2024/04/highspeed-etoile-racing-formed-hopes-to-support-women-racers/ inspired]] [[https://jp.motorsport.com/general/news/highspeed-etoile-racing-launch/10593916/ a tie-in promotional team]], HIGHSPEED Étoile Racing. The two racers, Kotomi Maeda and Ai Shimizu, both women, will compete in the KYOJO-CUP, Fuji Champion Race, and the EV-GP in Japan in the 2024 season. While intended to promote the anime, HIGHSPEED Étoile Racing also was formed to promote women as active participants in motorsports.

* ''Anime/KujibikiUnbalance'' was originally [[ShowWithinAShow an entirely fictional manga/anime]] within ''Manga/{{Genshiken}}''. When ''Genshiken'''s anime adaptation was released on DVD, three episodes of ''Kujibiki Unbalance'' were included as {{OVA}}s (which are meant to be the first episode, a Clip Show, and the second-to-last episode of the fictional anime), and later on it was remade into a real TV anime that follows a different continuity. When the characters within the original watched the real series the changes were incorporated ''back'' into the show! Later on, when the retooled ''Kujiun'' anime got a manga adaptation, it included a bonus {{omake}} chapter of ''Genshiken'' where they discussed the retooled ''Kujiun'' series becoming a manga and the changes made to it, including a LampshadeHanging ("[[WhoWouldWantToWatchUs Who the hell is Kio Shimoku?]]").

* In ''Manga/DemonSlayerKimetsuNoYaiba'', at the end of the series it is mentioned Zenitsu chronicled his life and that of his friends in a personal memoir book titled ''Zenitsu-den / The Legend of Zenitsu'', with contents of said book implied to be heavily dramatized and biased towards making Zenitsu more heroic than he ever was in reality, also making his friends look less impressive while at it. In an art gallery exhibition called ''Koyharu Gotouge Exibition'' which started its tour in Japan in October, 2021 a partial version of Zenitsu-den was produced for attendees to read in the exhibition, it contained a few full chapters of the book written from Zenitsu’s perspective and a table of contents, with titles for all 25 chapters The Legend of Zenitsu ended up with as Zenitsu finished writing it in his elderly years.[[labelnote:The Table of Contents in Zenitsu-den]]1.

[[spoiler:In his elder years Zenitsu grew wiser and chose to dedicate the last chapter of his book to telling the historical truth of what transpired in his life and of that his friends]].

* ''{{LightNovel/Durarara}}'' has an in-universe example where [[{{Otaku}} Walker and Erika]] have managed to defictionalize ''Anime/DarkerThanBlack'' protagonist Hei's trademark grappling knives, complete with a miniature generator to mimic his ShockAndAwe powers [[spoiler:for the purposes of [[TortureTechnician torture]]]]. In the real world, fans actually made a 'Dollars' board, complete with password and everything. (It's actually more along the lines of a fan forum, however.)

* ''Siscalypse'', the [[ShowWithinAShow Game Within a Show]] from ''LightNovel/{{Oreimo}}'', is seeing a RealLife version, albeit 2D rather than 3D as it was in the original.

* Anything ''Franchise/{{Pokemon}}'' related, usually in reference to [[Anime/{{Pokemon}} the anime]]. More recently, Ash's Pikachu, Ash & friends' Pokémon sent over Wi-Fi, eggs, etc.

* ''Anime/{{Pokemon}}'': The Ancient Mew Card seen in ''[[Anime/Pokemon2000 Pokémon the Movie 2000: The Power of One]]'' was made into a real card given out at cinemas showing the film in the U.S. with every ticket sale.
* ''Anime/HellGirl'' - [[http://jigokutsushin.co.nr/ The "real" Hell Correspondence website.]] [[spoiler: By the way, it doesn't work. If you watch the show, you should know that the process goes like: 1) Enter Target Name. 2) Click 'Submit'. 3) Ai Enma appears to give you the black straw doll with red string. 4) You pull the string. 5) Target goes to Hell. The site only goes until Step 2, so there's no black straw doll, so you can't send your target to Hell. So you need not fear having a certain black mark put on your neck setting ''you'' on the path to hell.]]
