History CassandraTruth / AnimeAndManga

* Tetsuo from ''Manga/{{Yuureitou}}'' tells Taichi that [[spoiler:he was Reiko, a woman who [[SelfMadeOrphan murdered her mother]] in a gruesome way two years ago and supposedly died.]] Taichi doesn't believe him because he's [[{{Transgender}} a trans man.]]

* "Kid" [[OlderThanTheyLook Conan]] in the ''Manga/DetectiveConan'' series knows about this problem, and solves it using a tranquilizer watch and a voice-changing bowtie to make it seem like someone more trustworthy in the eyes of the police is making all the deductions. [[EnforcedTrope Enforced]] because he can't afford to gain credibility: if his allies cotton on to his real identity it endangers them; if his enemies do it endangers ''him''.

** One of the most tragic examples comes when Lelouch, having just agreed with Euphie's terms behind the Special Administrative Zone, alludes to his power of Geass, but she doesn't believe him. He persists in giving more insidious possibilities of powers, until he just happens to be looking at her and says the wrong thing the moment PowerIncontinence hits.

* In ''LightNovel/FullMetalPanic'', when Sōsuke explains to Kaname that he's a soldier from an elite military unit on orders to protect her, Kaname informs him that he's delusional -- even as he's fighting off enemy soldiers and escaping with her across a military base. It's not until he climbs into an outdated HumongousMecha and [[SugarWiki/MomentOfAwesome kicks a world of ass with it]] that she realizes he's telling the unvarnished truth.

** In Episode 3, Homura tells Mami that the witch Charlotte is not like the other witches she's faced before and that she should avoid fighting it, but Mami disregards he and uses her magic to tie Homura up so she can't follow her. [[spoiler: Homura is a time-traveler and knows that Charlotte will kill Mami, which is exactly what happens.]]

* In ''Webcomic/AxisPowersHetalia'', England can see magical creatures while only a few other nations can (Norway and Romania). Thus nearly every other nation thinks he's gone insane when they find him talking to the air. In one strip, France, trying to get England for a meeting, walks in and sees a mob of fairies, unicorns and gnomes surrounding a sleeping England, and his reaction is hilarious.

* ''Anime/CodeGeass''

* ''Anime/{{Doraemon}}'': Occurs in [[Recap/Doraemon1979E1759SoapBubbles "Soap Bubbles"]].

* In ''Manga/MahouSenseiNegima'', Negi Springfield (though it is admittedly his fault) makes a good attempt at warning the other mage teachers about the existence of a TimeMachine which could be used to SetRightWhatOnceWentWrong. Somehow, even full-fledged mages refuses to accept the idea of time travel. Also, nobody believes Chao the first time she tells everybody she's in truth "an alien from Mars." And still... Truth be told, Negi himself had it coming since the other mage teachers tried to convince him that Chao was on the verge of causing serious problems and [[UnwittingPawn he didn't listen to them]].

* ''LightNovel/HighSchoolDxD'': While fighting Loki, the protagonist Issei [[spoiler: accidentally summons a ''breast god''. No one believes him, not even when ''[[CosmicPlaything Ddraig]]'' had to explain that yes, he did hear the voice.]]

* In ''LightNovel/LevelUpJustByEating'', nobody ever believes that Laura is a goddess, even when she performs miracles, for pretty much the same reason nobody believes Aqua in ''LightNovel/KonoSuba''.

* In ''Anime/DragonBallZ'', Bardock attempts to warn a bar full of Saiyans that Freeza is coming to kill them. But they openly mock him, forcing Bardock to face Freeza and his men alone.

* In episode 46 of ''Anime/{{Tamagotchi}}! Yume Kira Dream'', Nandetchi thinks Yumemitchi and Kiraritchi are the mysterious Tamagotchis who pop up as girls of different occupations. He's right in that they are, but Mametchi and his friends don't believe him when he says this to them, so he sets off to expose their identities - which is bad news for Yumemitchi and Kiraritchi because the lady who gave them their Yume Kira bags, which is what gives them the power of different jobs in the first place, told them that they must not let anyone know it's really them. [[spoiler:When Nandetchi gets stuck inside a giant robot, is saved by the girl duo, and realizes he was right, he decides to be nice and destroys the photos he got of them transforming.]]

** Kaname is similarly incredulous when Sousuke tries to explain that [[NotWhatItLooksLike the cute teenage girl who just came out of his bathroom in nothing but a towel]] is his commanding officer, not his girlfriend. It didn't help that Tessa actually quite likes the idea of being mistaken for his girlfriend and deliberately employs BadBadActing when confirmation the story in order to undermine his case.

** Kaname is similarly incredulous when Sousuke tries to explain that [[ItsNotWhatItLooksLike the cute teenage girl who just came out of his bathroom in nothing but a towel]] is his commanding officer, not his girlfriend. It didn't help that Tessa actually quite likes the idea of being mistaken for his girlfriend and deliberately employs BadBadActing when confirmation the story in order to undermine his case.

** The manga version has Ayame walk-in on Tanukichi and Oboro in the girls' locker-room and finds them [[NotWhatItLooksLike in a compromising position.]] So Ayame jumps to [[DidYouJustHaveSex the obvious conclusion]] and ducks back outside. Tanukichi goes after her to explain what really happened, but she doesn't believe him.

* While fighting Loki in ''LightNovel/HighSchoolDXD'', the protagonist Issei [[spoiler: accidentally summons a ''breast god''. No one believes him, not even when ''[[CosmicPlaything Ddraig]]'' had to explain that yes, he did hear the voice.]]

** Haruka is accused of this with her [[{{telepathy}} mind reading abilities]], particularly when she was younger, when she was said to be a ''compulsive liar'' as she {{innocently|insensitive}} blurt out other people's inner thoughts and secrets. This is not helped by the fact Japanese do have a tradition of lying to conform with social norms, and her case of PowerIncontinence makes it her for her to distinguish between speech and thoughts.

* ''Manga/MyHeroAcademia'': After the first combat training class, [[TheRival Bakugo]], feeling humiliated, decides to storm out of school because he's angry about the humiliation coming at the hands of [[TheHero Izuku]], since he [[EntertaininglyWrong assumes]] that Izuku was mocking him by hiding his Quirk for their whole lives. Izuku tries to stop him by telling him the truth, that he was recently [[SuperEmpowering given]] his Quirk by someone else. As per this trope, Bakugo doesn't believe it, and thinks Izuku is trying to play him for a fool.
** [[spoiler:Later, it's eventually subverted: the confession and the circumstances surrounding All Might's retirement lead Bakugo to put two and two together and realize both that Izuku was telling the truth ''and'' who he got his Quirk from. Bakugo later reveals this to Izuku during the trials for earning provisional hero licences.]]

* ''Manga/MyHeroAcademia'': After the first combat training class, [[TheRival Bakugo]], feeling humiliated, decides to storm out of school because he's angry about being humiliated, in his opinion, by [[TheHero Izuku]], since he [[EntertaininglyWrong assumes]] that Izuku was mocking him by hiding his Quirk for their whole lives. Izuku tries to stop him by telling him the truth, that he was recently [[SuperEmpowering given]] his Quirk by someone else. As per this trope, Bakugo doesn't believe it, and thinks Izuku is trying to play him for a fool.

* Any hero in the ''Franchise/DotHack'' franchise can't even get to telling their parents or the authorities; despite mass server failures, clear evidence of a conspiracy or two, people [[TrappedInAnotherWorld trapped in the game]], [[EverythingIsOnline machine problems everywhere]] and ''comas'', who would believe that an MMORPG was SeriousBusiness?

** As is its fashion, ''Manga/ElfenLied'' provides a particularly brutal example between Nana and CuteMute Nyuu: Nana knows that Nyuu has an alternate personality called Lucy who is an AxCrazy mass murderer, but no-one else believes her.

* Poor Rika in ''VisualNovel/HigurashiWhenTheyCry''. She ''tries'' to warn Tomitake and Takano, but do they ever listen to her? No; she barely comes up to their bellybuttons. (Actually, at one point Takano does seem to acknowledge Rika's foresight, but [[spoiler:that's only because she knows what's going to happen; it's ''her'' Evil Plan.]])
* Light Yagami of ''Manga/DeathNote'' subverts this several times, at one point "[[SarcasticConfession admitting]]" that he might be Kira so he can be locked up in order to prove that he isn't Kira and renounces possession of the Death Note so he can [[MemoryGambit lose his memory]], thus playing the role of innocent even more. It is AllAccordingToPlan.
* In ''LightNovel/FullMetalPanic'', when Sōsuke explains to Kaname that he's a soldier from an elite military unit on orders to protect her, Kaname informs him that he's delusional -- even as he's fighting off enemy soldiers and escaping with her across a military base. It's not until he climbs into an outdated HumongousMecha and [[SugarWiki/MomentOfAwesome kicks a world of ass with it]] that she realizes he's telling the unvarnished truth.

Truth be told, Negi himself had it coming since the other mage teachers tried to convince him that Chao was on the verge of causing serious problems and [[UnwittingPawn he didn't listen to them]].
* ''Manga/{{Bleach}}'':
** When Ishida first appeared in Soul Society, Mayuri realised that Soul Society was vulnerable to Quincy attack and, because Yamamoto had failed to kill an old enemy in the past, a Quincy attack is precisely what was going to happen. Yamamoto dismissed Mayuri's advice as paranoia, and that was a fatal mistake.
** Happens to Ichigo when his futile attempts at trying to tell everyone that Tsukishima is a villain, but because of all the FakeMemories they've been implanted with, they're more convinced that Ichigo is the real problem.
* In ''Webcomic/AxisPowersHetalia'', England can see magical creatures while only a few other nations can (Norway and Romania). Thus nearly every other nation thinks he's gone insane when they find him talking to the air. In one strip, France, trying to get England for a meeting, walks in and sees a mob of fairies, unicorns and gnomes surrounding a sleeping England, and his reaction is hilarious.
* In ''Anime/DragonBallZBardockTheFatherOfGoku'', Bardock is given the power to see the future. However, [[spoiler:he sees their planet being destroyed by Freeza.]] Naturally, no one takes him seriously.
* In ''Franchise/LyricalNanoha'', one of the known stories about the legendary lead character is how she became a [[RankInflation AAA-Rank mage]], solved her [[TheEndOfTheWorldAsWeKnowIt first Interdimensional Incident]], and destroyed a WeaponOfMassDestruction [[NighInvulnerability said to be impossible to destroy]] at the age of ''[[ImprobableAge nine]]''. Non-fans like Teana, naturally, dismiss it.
--> '''Teana:''' That just sounds like a rumor. [[ImprobableAge What kind of nine year old was she?]]
** Three years later, after Teana being shot down by her instructor Nanoha in a mock battle, Shario shows the Forwards a video documentation of Nanoha's life, showing that the rumor was true, and how Nanoha's high magic power in her young age and her TrainingFromHell could destroy her body.
* Nobody believes that ''[[LightNovel/BakaAndTestSummonTheBeasts Akihisa Yoshii]]'' knows how to cook because for those few episodes, we see him only eating sugar. Imagine everyone's surprise when he cooks ''paella''.
* ''Manga/{{Monster}}''. Poor, poor Tenma. Try as he might, barely anyone will believe his story of a ten-year-old child committing serial murders.
* ''Manga/FullmetalAlchemist''.
** When Mustang is looking for some allies in the military brass, he mentions a few "strange rumors" to General Raven, including Scar liking cats and [[spoiler:Furher Bradley being a homunculus.]] Raven brushes it off as a bad joke from Mustang. [[spoiler:Then immediately subverted when Raven leads Mustang into the [[AncientConspiracy meeting with all the top generals]] and [[OhCrap ominously asks him to continue his "joke".]]]] Sometimes not being believed is not as bad as being believed by the WRONG people.
** Played straight in the first (non-manga) episode where the renegade Freezing Alchemist is trying to destroy Central City to stop a government conspiracy at the highest levels.
* ''Anime/CodeGeass''
** One of the most tragic examples comes when Lelouch, having just agreed with Euphie's terms behind the Special Administrative Zone, alludes to his power of Geass, but she doesn't believe him. He persists in giving more insidious possibilities of powers, until he just happens to be looking at her and says the wrong thing the moment PowerIncontinence hits.
** Also in season 2 episode 18 where Suzaku has a hard time warning Lelouch of the FLEIJA due to Schneizel's manipulations having broken their friendship.
* The creator of ''Manga/{{Gantz}}'' actually reveals the entire story of the Gantz operation to a reporter who confronts him for the truth. He then invokes this trope by saying that he told the entire truth because it's so outrageous that no one would believe anyone who exposed the story.
* In ''Manga/NatsumesBookOfFriends'', Natsume was typically regarded as an attention-seeking liar whenever he told people about the [[ISeeDeadPeople spirits and monsters only he could see]].
* ''Manga/SatouKashiNoDanganWaUchinukenai'':
** Nagisa doesn't believe her friend [[CloudCuckoolander Mokuzu]] when she tells her that [[spoiler:her father killed her dog.]] Turns out she's not making this up for a change.
** Later on Nagisa's teacher and mom don't believe her when she says [[spoiler:Mokuzu's dad [[OffingTheOffspring killed her.]]]] They just think she's playing a prank since Mokuzu is known for lying. Her brother ''does'' believe her, however, even [[HikikoMori leaving the house after years]] to help her out. [[spoiler: Then, they find Mokuzu's corpse...]]
* ''Anime/PuellaMagiMadokaMagica'' has a tragic example in which Homura [[spoiler: in the [[GroundhogDayLoop third time-loop]]]] tries to explain [[spoiler: that Kyubey had been lying to the girls and has been orchestrated their transformations into witches]]. Not only does everyone not believe her, but when [[spoiler: Sayaka]] finally does turn into a witch, the consequences lead to one of the worst events [[spoiler: of all the loops]].
* ''Anime/Persona4TheAnimation'' has Yukiko and Rise telling Naoto all about the world inside the TV and Personae. Naoto doesn't believe them. Though admittedly, they were [[DrunkOnMilk "drunk"]] at the time. Later on, Yu tells the police chief the same thing, and once again he isn't believed.
* In ''Manga/BlueExorcist'', at one point Shura douses everyone in holy water to ward off demons - everyone except Rin, that is. When the others suspiciously question her visible hesitation, she answers that he's allergic to holy water, as ridiculous as that sounds. An episode later, the team is in a sticky situation when Rin unexpectedly announces that he was never good at lying and unleashes the signature blue {{Hellfire}} that's supposed to be the trademark of {{Satan}}. Another episode later, the kids find out what the audience already knew from episode two: Rin's biological father is none other than Satan himself, making him a [[AntiAntiChrist half-demon]]. As Shura put it earlier, pouring holy water onto the poor boy [[ItBurns wouldn't have been a pretty sight]].
* While fighting Loki in ''LightNovel/HighSchoolDXD'', the protagonist Issei [[spoiler: accidentally summons a ''breast god''. No one believes him, not even when ''[[CosmicPlaything Ddraig]]'' had to explain that yes, he did hear the voice.]]
* ''Manga/KotouraSan'' is a RomanticComedy that sets in an universe where... psychics actually exists, but {{muggles}} don't even know its existence. Psychics, then, often subjected to this trope.
** Haruka is accused of this with her [[{{telepathy}} mind reading abilities]], particularly when she was younger, when she was said to be a ''compulsive liar'' as she {{innocently|insensitive}} blurt out other people's inner thoughts and secrets. This is not helped by the fact Japanese do have a tradition of lying to conform with social norms, and her case of PowerIncontinence makes it her for her to distinguish between speech and thoughts.
** Yuriko's mother Chizuru was a clairvoyant, but was DrivenToSuicide after falsely accused to have faked her powers. Even now, most people see her powers as a fake, with the exception of Yuriko herself and her ChildhoodFriend Dai'chi.
* In ''Manga/LuckyStar'', nobody – not even his daughter Konata – believes that Soujirou is actually a hardworking writer who can write wholesome, non-otaku-related topics, has quite a bit of book smarts, has had a relationship with Kanata that was far beyond paedophilia, so on and so forth.
* With thanks to the [[MaskOfPower Rabbit of Truth]], Alice from ''Manga/TheVoynichHotel'' can see [[TrueSight past glamours and illusions for what they really are.]] Fortunately, mere mortals need never bother with solving supernatural problems, most of the time.

* Comes up twice in ''Manga/{{Shiki}}''. The first is when Ikumi Itou, the village's shaman, becomes aware that the vampire family that moved into town is nothing but trouble, but everyone dismisses her as a crazy old woman. The second is when a housewife named Motoko Maeda tries to get help for her family as they're slowly killed by vampires, but none of her other family members believe her until they themselves are killed. The former case is a bit complex, though, since at the time Ikumi is trying to rally the villagers, Dr. Toshio Ozaki ''does'' know about the vampires but doesn't want the truth getting out, so he pretends not to believe her and tries to discredit her.
* No one at the hospital believes Kurosu from ''Manga/AnaSatsujin'' when he says [[spoiler:his wife]] is trying to [[BlackWidow kill him]]. He nearly died so they assume he's confused or still under the medication.
* Yun from ''LightNovel/OnlySenseOnline'' is an unwilling CrossPlayer in the titular game, as a result of the game system misidentifying his sex. Despite his consistent usage of masculine speech and repeated attempts to deny that he is a girl, nobody other than his real life acquaintances believe him and assume instead that he is roleplaying as an OreOnna.
* During the Synchro dimension arc of ''Anime/YuGiOhArcV'', nobody outside of [[spoiler: Jean, who is from the Fusion dimension, and the Executive Council, who have been trying to manipulate him in order to maintain their own security]], believes that the inter-dimensional war is real. Attempts to explain it to people have been ignored, even after [[spoiler: Jean and the Council]] admit the truth in front of a handful of Synchro characters, said characters have varying opinions on what's "really" going on.
* PlayedForLaughs in ''Manga/{{Ojojojo}}'' when Haru called Tsurezure's house and introduced herself as [[spoiler: his girlfriend]]. His older sister thinks its a prank call and promptly hangs up the phone.
* In the third episode of ''Anime/YoKaiWatch'', [[KnowNothingKnowItAll Whisper]] insists that nobody's ever seen a Noko and never will, even when Nate has one right next to him that eventually escalates to a whole bunch of them in his room, because they immediately disappear everytime Whisper turns around. Whisper even grabs one of them instead of his Yo-Kai Pad and still can't see that he did because he closed his eyes.
* In ''Manga/NurseAngelRirikaSOS'' Seiya tries to convince Ririka that [[spoiler:the recently revived Kanou]] is involved with the BigBad now. Seiya tries to tell his classmates the truth as well but no one believes that [[spoiler:Kanou]] is an alien from another dimension who works with a group of evil psychics.
* During the Death 13 arc of ''Manga/JojosBizarreAdventureStardustCrusaders'', Kakyoin is the only one to recognize the EnfanteTerrible Mannish Boy as the stand-user of Death 13. (Death 13 only works in dreams, and erases the victim's memory after they wake up. Kakyoin managed to bypass it by carving notes into his skin, which caused his group to question his sanity.)
* One episode of ''Anime/LaytonMysteryDetectiveAgency'' revolves around the gang trying to catch a PhantomThief who turns out to be [[spoiler:a ChildProdigy who had developed a super-computer that can essentially predict the future. While gathering data for the computer, he had discovered that one of the tunnels beneath London was close to collapse, but when he tried warning Scotland Yard, they refused to listen to him due to his age. His string of robberies had been a last resort: the street above the tunnel was cordoned off as part of the investigation, and when the subsistence happens just as he'd predicted, nobody is hurt.]]
* When Minaha asks for Iris to autograph her game in episode 8 of ''Manga/MagicOfStella'', Ayame walks up and signs it. Minaha then tells Ayame off and says not to pretend to be Iris. Iris is Ayame's PenName.
* ''LightNovel/{{Shimoneta}}'' uses the same gag in manga chapter 10/anime episode 9 respectively, though it differs in how it plays out:
** The manga version has Ayame walk-in on Tanukichi and Oboro in the girls' locker-room and finds them [[NotWhatItLooksLike in a compromising position.]] So Ayame jumps to [[DidYouJustHaveSex the obvious conclusion]] and ducks back outside. Tanukichi goes after her to explain what really happened, but she doesn't believe him.
** In the anime, Anna is the one who walks in on them, causing Tanukichi to flee the locker-room to escape her. When he reports back to Ayame to explain why he hadn't caught the underwear thieves, he mentions that he found out Oboro [[spoiler: [[DudeLooksLikeALady is really a guy]]]]. Ayame dismisses it as a lame excuse, saying there's ''no way'' that could be true.
* ''Anime/SerendipityThePinkDragon'': Without proof of the island's existence, Smudge is reduced to ranting which is promptly ignored by the other humans.
* PlayedForLaughs in ''Manga/MonkeyHigh''. Macharu brings Haruna home, and he introduces her to his mother as his girlfriend. As Macharu is regularly described as looking like a baby monkey, and Haruna is a mature and ladylike {{Ojou}}-type, Macharu's mother's response is to give Macharu a DopeSlap and to tell him to stop lying. Haruna then pipes up to tell her that it's true, with Macharu's mother in such shock that she has to run and tell his father - who is so shocked that he digs out a camera to make sure there's photographic evidence of it all, because he can barely believe it even after getting multiple confirmations. Macharu is [[AmazinglyEmbarrassingParents completely mortified of all of this]].
