History Unperson / AnimeAndManga

* ''Literature/CrestOfTheStars'': This is done as a ''reward'' by the creator of the "Abh Hell". Though the Abh as the whole don't believe in an afterlife they created a living hell as a place of [[FateWorseThanDeath torture for their worst enemies.]] The opening narration of one episode recounts the meeting of the Emperor who commissioned its creation, offering the creator any reward they desired. [[MoralEventHorizon Knowing full well the magnitude of the horror they have made]], the unnamed creator's only request is to be erased from history, a request the Emperor grants. There are only two pieces of evidence that the man existed left: the fact that the Abh Hell exists, and the record of the conversation in which the creator asks to be erased from history, which is listed as being between Emperor Dugnac and an anonymous individual.

** In ''Manga/PuellaMagiKazumiMagica'', it's eventually revealed that A) [[spoiler: Jyuubey is not the Incubator who created the Pleiades Saints; they erased Kyuubey and enchanted one of his corpses to become his replacement]] and B) [[spoiler: Niko did this to ''herself'' with her doppelganger power, so the her who lived her life would not have the guilt of accidentally murdering one of her childhood friends]]. Both of these have consequences: A) [[spoiler: Kyuubey is still able to recruit ''other'' magical girls without the Pleiades' interference, since they cannot detect him]], and B) [[spoiler: Niko's replacement has a nasty case of the CloningBlues after Kyuubey informs her of her nature]].

** Related to the above, Gol D. Roger has a slight version of this done to him. As he gains notoriety and power, his wanted posters are changed from "Gol D. Roger" to "Gold Roger" to hide his connection to the Will of D. What the Will of D is precisely isn't known as of now, but it terrifies the upper echelon of the World Government. As erasing Gol D. Roger is harder than Rocks, not helped by the man's public execution and his premortem declaration of his treasure spurring a whole generation of pirates, they have settled to just a MaliciousMisnaming. [[spoiler:They later try to do the same thing to Luffy after he becomes one of the Four Emperors, by trying to remove the "D" in his name for his latest wanted poster.]]

** [[spoiler:The World Government and the Marines do this to the Lulusia Kingdom, when they discover Sabo is currently there trying to relay the information about the Empty Throne to the Revolutionary Army, at which point Imu erases the country with an unknown weapon or ability, and the Elder Stars order their subordinates to pretend that the kingdom never existed. Luckly, Sabo is revealed to have left Lulusia before its destruction.]]

** The World Government did this with Rocks D. Xebec and the Rocks Pirates. Rocks was man so powerful and dangerous that it took the combined efforts of Monkey D. Garp and Gol D. Roger to take him down. The island the battle took place vanished off the map (or so it's said), and only a few people still alive know of him and his dangerous crew (which included future Emperors like Whitebeard, Kaido and Big Mom, as well as other legends like Shiki and Captain John). Those who were there among the Marines refuse to speak of him and advise to stay out of it, and those that once worked in his crew never bring him up because [[TeethClenchedTeamwork they weren't fond of the era nor their crewmates]].
** Related to the above, Gol D. Roger has a slight version of this done to him. As he gains notoriety and power, his wanted posters are changed from "Gol D. Roger" to "Gold Roger" to hide his connection to the Will of D. What the Will of D is precisely isn't known for now, but it terrifies the upper echelon of the World Government. As erasing Gol D. Roger is harder than Rocks, not helped by the man's public execution and his premortem declaration of his treasure spurring a whole generation of pirates, they have settled to just a MaliciousMisnaming.

* ''{{Anime/K}}: Return of Kings'': It is revealed that [[spoiler: as part of the plan to force Weismann to come down from his airship, the Green Clan did this to Tooru Hieda, the boy who's body the Colorless King stole in season 1, which is why not even Scepter 4's surveillance systems could identify the culprit in the video that shows the Colorless King in Tooru's body committing a murder.]]

** [[spoiler:Tsukishima's death]] undoes his power and all his effects. His victims also forget all about him, even his very existence and despite remembering everything else.

* ''Literature/CrestOfTheStars'': This is done as a ''reward'' by the creator of the "Abh Hell". Though the Abh as the whole don't believe in an afterlife they created a living hell as a place of [[AFateWorseThanDeath torture for their worst enemies.]] The opening narration of one episode recounts the meeting of the Emperor who commissioned its creation, offering the creator any reward they desired. [[MoralEventHorizon Knowing full well the magnitude of the horror they have made]] the unnamed creator's only request is to be erased from history, a request the Emperor grants.

* ''Manga/HowToMakeAnInvisibleMan''" Becoming "invisible" doesn't just mean nobody can see you. It means nobody can see you, hear you, notice your presence, or even remember you, even if they are family, friends or lovers. You even disapear from the photos where you were. Your existence is erased from the world. [[spoiler:But even with that, Kana keeps a vague, residual feeling of having lost something; [[ThePowerOfLove her bond with Shinji is just that strong.]]]]

** The Donquixote Family member Sugar has this as a side effect of her Devil Fruit. The main power of her Hobi Hobi No Mi (Hobby-Hobby Fruit) is that it turns people she touches into toys that she can then place under her total control. The side-effect is that all memory of her victims is erased from those who knew them, though physical evidence still remains.

** Related to the above, Gol D. Roger has a slight version of this done to him. As he gains notoriety and power, his wanted posters are changed from "Gol D.

** [[spoiler:The World Government goes to the extent of pretending a particular Devil Fruit is a Paramecia-class by calling it a fake name, the Gomu Gomu no mi, in an attempt to obscure its true abilities, the existence of Joy Boy and the Fruit's true name, the Zoan-type Hito Hito no mi Model: Nika. The only mention of the name comes from an indestructible poneglyph and the hearsay passed around among slaves who mention the legend of the Sun God Nika -- other than that, there are no indications that the fruit is anything special nor that any of the names involved are related to one another. When it awakens, [[DeusExMachina nobody has any context]] for ''how'' Luffy's suddenly pulling off all these fantastical abilities (besides the Five Elders, who are, at the time, unaware that Luffy has managed to awaken the fruit), but Luffy is more focused on putting them to use against Kaido]].

* ''LightNovel/TheExecutionerAndHerWayOfLife'': Ivory was completely erased from all historical records by the Faust, with his role in defeating the Four Major Human Errors instead being attributed to Church agents.

* ''LightNovel/ShakuganNoShana'': A large amount of people have had their power of existence consumed and turned into torches. When a torch's flame dies out, they disappear completely, as if they never existed. No-one will have any memories of them and evidence that hinted towards their existence such as photographs fade away as well.

* ''Anime/{{Monster}}'': Johan Liebert is notable since the one who is removing the evidence of his existence is himself. [[spoiler:He also did the same to General Wolf. All because the poor sap at one point asked him "how he felt".]]

** The prison [[TheAlcatraz Impel Down]] has a total of six levels. However, the sixth level of the prison which is reserved for those who are most dangerous (whether to society or simply the World Government), does not officially exist, which also applies to the prisoners of that level, most of whom have records of their existence erased after being imprisoned.

* ''Anime/PuellaMagiMadokaMagica'': This happens to [[spoiler: Madoka. She traded all trace of her existence for a happy afterlife for corrupted magical girls]].

* ''Manga/ShuumatsuNoWalkureRecordOfRagnarok'': This is the in-universe reason for why [[CanonForeigner Adamas]] doesn't exist in actual [[Myth/ClassicalMythology Greek Mythology]]. After being killed by Poseidon, Poseidon had any existing record of him destroyed, as he considered him such an embarrassment that he didn't want anyone else to even know he existed. As a result, only a small handful of people like Hermes and Brunhilde know he existed, with even younger divinities like Göll being unaware of him.

* ''Manga/YuGiOh'': Happens to the Pharaoh, or 'Yami Yugi' as he's known. When he was king he sacrificed his life, name and memories to seal away the Shadow Games and Zorc, effectively wiping himself from history except in vague records. Upon first release 3,000 years later he seems to have adopted the identity of a dark avenger, since his magic is all he knows about himself. A theme of the series is his quest for a separate identity, as even Yugi's friends still refer to him as the other Yugi or just Yugi after learning of his past life.

** The prison Impel Down has six levels. The sixth level of the prison -- reserved for those who are most dangerous (whether to society or simply the World Government) -- does not officially exist; the same could be presumed of its inhabitants. [[spoiler:Which is why several of them escaping was covered up.]]
** The Donquixote Family member Sugar has this as a side effect of her Devil Fruit power. The main power of her Hobby-Hobby Fruit is that it turns people she touches into toys that she can then place under her total control. The side-effect is that all memory of her victims are erased from those who knew them, though physical evidence still remains.

** The World Government goes to the extent of pretending a particular Devil Fruit is just [[spoiler:the Paramecia-class Gum-Gum Fruit]] in an attempt to obscure its true abilities, [[spoiler:the existence of Joy Boy]] and the Fruit's true name, [[spoiler:the Zoan-type Human-Human Fruit, Model: Nika]]. The only mention of the name comes from an indestructible poneglyph and the heresy passed around among slaves of [[spoiler:the Sun God Nika]] -- other than that, there are no indications that the fruit is anything special nor that any of the names involved are related to one another. When it awakens, [[DeusExMachina nobody has any context]] for ''how'' [[spoiler:Luffy's suddenly pulling off all these fantastical abilities]] (besides the Five Elders, who are, at the time, unaware that [[spoiler:Luffy has managed to awaken the fruit]]), but [[spoiler:Luffy is more focused on putting them to use against Kaido]].
** The World Government and the Marines do this to [[spoiler:Lulusia Kingdom, where Sabo was last at when he tried to relay the information that Imu is the ruler of the World Government, at which point Imu erases the country and the Marines order their subordinates to pretend they didn't hear it.]]

* ''Manga/FairyTail'': In a filler episode of the anime, an ointment Lucy made before the TimeSkip causes her to become invisible. However, it turns out the ointment doesn't just erase her from people's sights but also begins to erase her from existence, such as preventing her from using her Celestial Magic to summon her spirits or making the clothes she's wearing disappear. Soon, she becomes completely undetectable by her guildmates, who soon forget she even existed as they wonder what they were doing before hand. Thankfully, Natsu instinctively calling for Lucy to come with him for a job [[PowerOfFriendship causes him to remember]], which soon spreads to everyone else and breaks the spell on Lucy. Of course, Lucy's attempt to get rid of the cursed ointment is foiled when Happy crashes into her, causing it to turn everyone but her invisible and potentially subject them to the same fate.
