History StealthHiBye / AnimeAndManga

* In the anime adaptation of ''LightNovel/LoveChunibyoAndOtherDelusions'', Dekomori comes out of nowhere to slide tackle Shinka while the latter is sitting in art class, then runs back out the door. They aren't even in the same grade (Shinka is in high school while Dekomori is still in middle school).

* In ''LightNovel/ThePetGirlOfSakurasou'', Mashiro does this to Sorata in episode 2 when he comments on a beautiful painting he saw in a book. [[spoiler:Which turns out to be Mashiro's.]]

* ''LightNovel/RebuildWorld'':

* Xellos, from ''LightNovel/{{Slayers}}'', frequently uses this... and when he doesn't, it's because he's using OffscreenTeleportation or onscreen teleportation instead. Seriously, he ''never'' makes entrances or exits normally. He kind of subverts it in that he doesn't need you to look away: he'll teleport anyways.
* ''LightNovel/SoImASpiderSoWhat'': Shiraori has a habit of doing this with Transfer, sometimes appearing just long enough to leave a poorly-phrased message before leaving.

* ''Lightnovel/SwordArtOnline'': Death Gun pulls a Stealth Hi on Kirito in ''Gun Gale Online''. By virtue of having an InvisibilityCloak, he can quickly appear and disappear at will.

** Used in the fourth episode of the anime; Rena is walking down the road a few dozen feet away, Keichi looks away for a second, and then Rena is suddenly standing right behind him... With a cleaver in her hand...
--->'''Rena:''' ''Found you~'', Keichi...
** However, this might be a subversion, as it's later revealed that Keichi was suffering from the (extreme) [[HatePlague paranoia-inducing disease]] that drives the plot. It's [[ThroughTheEyesOfMadness unlikely]] that the cleaver was really a cleaver, though some fans [[AlternateCharacterInterpretation theorize]] she did carry one in another screen (for non-malicious reasons).

* A RunningGag in ''Anime/InazumaEleven'' involves Kageno sneaking behind people's back, which unintentionally scares them, which is not helped by the fact that he's so [[TheQuietOne quiet]] most of the time and only gets noticed when he speaks.

* ''Anime/GoPrincessPrettyCure'''s housekeeper Shirogane-san does this at least once every few episodes.

* In the ''[[Manga/HarukanaruTokiNoNakaDe Harukanaru Toki no Naka de - Hachiyou Shou]]'' OAV episode "Omoi no Arika" there's a running gag consisting of [[UsefulNotes/{{Onmyodo}} Yasuaki]] suddenly appearing just in the wrong place and time; the Stealth Hi/Bye ability gets [[LampshadeHanging lampshaded]] by Tenma at on point. On one occasion, Yasuaki scares Shimon by popping up from nearby bushes; another scene has him emerging from behind Tenma, prompting the latter to unleash TheScream. Worth noting that the characters are trying to hide something from him, so, of course, most of the time he appears when they're talking about it...

* Schrödinger of ''Manga/{{Hellsing}}'' is introduced this way, teleporting straight into a top-secret meeting. His [[TechnoBabble consciousness-defined existence]] lets him do that. And makes him immortal.
** Alucard does this too, walking through walls behind people.
* ''VisualNovel/HigurashiWhenTheyCry'':

* A RunningGag in ''VideoGame/InazumaEleven'' involves Kageno sneaking behind people's back, which unintentionally scares them, which is not helped by the fact that he's so [[TheQuietOne quiet]] most of the time and only gets noticed when he speaks.

* ''Manga/OnePiece''. Lafitte surprises everyone in the big Marine meeting in their very headquarters when he suddenly appears in the room. While wearing tapping shoes.

* Reina from ''Literature/SoundEuphonium'' is prone to doing this to Kumiko.
* ''Lightnovel/SwordArtOnline'': Death Gun pulls a Stealth Hi on Kirito in ''Gun Gale Online''.

* ''VisualNovel/UminekoWhenTheyCry''. Kanon tends to do this with his sister Shannon. [[spoiler: Later this is completely justified with the reveal that Kanon and Shannon are the same person and so his appearance and disappearance is only in [[SplitPersonality her head]]]].

* Hakim from ''Manga/EmmaAVictorianRomance'' is fond of suddenly appearing in his friend William's house, right behind him, without warning.

* A RunningGag in ''Anime/InazumaEleven'' involves Kageno sneaking behind people's back, which unintentionally scares them, which is not helped by the fact that he's so [[TheQuietOne quiet]] most of the time and only gets noticed when he speaks.

* ''Manga/{{Bleach}}'': Captains like doing this. Lampshaded in [[{{Manga}} Chapter 99]] ([[{{Anime}} Episode 34]]) by Hinamori. She doesn't realise Byakuya is behind her until he speaks, almost scaring her out of her wits. When he's gone, she doesn't realise Gin is leaning against a wall until he speaks, again almost scaring her out of her wits. When Gin is gone, she doesn't realise Hitsugaya is standing right by her side until he speaks, at which point she explodes.

* In the ''Manga/BlueExorcist'' manga, this happens in Chapter 22. Performed by ''[[IdiotHero Rin]]'' of all people! Justified by the fact he's a) the [[AntiAntiChrist Son]] of {{Satan}} and thus has a lot of natural potential, and b) [[spoiler:Bon just hit a BerserkButton of his that made him recall his foster father's HeroicSacrifice]] resulting in a meltdown.

* Hei from ''Anime/DarkerThanBlack'' is a grandmaster of this trope, capable of even vanishing in a fully lit corridor from someone he was walking alongside no more than two feet away. This is part of why he's [[FanNickname known as Chinese Electric Batman]].

* Hakim from ''Manga/VictorianRomanceEmma'' is fond of suddenly appearing in his friend William's house, right behind him, without warning.

* ''Anime/{{Pokemon}}'':

* ''Manga/RosarioToVampire'':

* ''VisualNovel/HigurashiWhenTheyCry''

* Kyo Toba, a minor character from ''Lagoon Engine'', does this all the time. In an interesting variation, it's not that he enters or leaves the room, but that he has such a weak presence that people forget he's there almost as soon as they look away. He's also TheFaceless for the same reason; even his own immediate family can't remember what his face looks like.

* Nobody ever sees Himari's penguin hat appear on her head in ''Anime/MawaruPenguindrum''; often it remains unnoticed until "[[DerangedAnimation SURV]][[TransformationSequence IVAL]] [[IncomingHam STRATEGY!!]]" At least once, it isn't seen until it makes a comment as though it was part of the conversation the whole time -- cue gawking and, moments later, the aforementioned announcement.

* ''Anime/{{Pokemon}}''

* ''Anime/SailorMoon''

* Parodied in ''Anime/KidouTenshiAngelicLayer'', where Icchan always makes over-the-top, utterly ridiculous entrances out of nowhere and his disappearances are, half the time, caused by either his co-workers calling him to ask where on earth he is or bystanders reporting him as a creepy-looking MadScientist hanging around a little girl.

* The main character of ''[[Manga/KurokoNoBasuke Kuroko No Basket]]'' has next to no presence, so whenever he talks to someone else, they have no idea where he came from or how long he's been there.

* In ''Anime/MobileSuitGundam00'', [[ChasteHero Setsuna F. Seiei]] sneaks into [[EverythingsBetterWithPrincesses Marina Ismail's]] bedroom late at night. He quietly leaves her near the end of her speech while she was looking down.

* ''Anime/KaitouJoker''. Dark Eye pulls this in his debut episode.

* In ''Anime/{{Gundam 00}}'', [[ChasteHero Setsuna F. Seiei]] sneaks into [[EverythingsBetterWithPrincesses Marina Ismail's]] bedroom late at night. He quietly leaves her near the end of her speech while she was looking down.

* ''Manga/UminekoWhenTheyCry''. Kanon tends to do this with his sister Shannon. [[spoiler: Later this is completely justified with the reveal that Kanon and Shannon are the same person and so his appearance and disappearance is only in [[SplitPersonality her head]]]]..

Worth noting that the characters are trying to hide something from him, so, of course, most of the time he appears when they're talking about it...

* [[TricksterMentor Kujaku]] does this all the time in ''Anime/RGVeda''.

* ''Manga/TenchiUniverse''. Sasami manages to pull this off against Tenchi in her first appearance.

* A RunningGag in ''Anime/InazumaEleven'' involves Kageno sneaking behind people's back, which unintentionally scares them, which is not helped by the fact that he's so [[TheQuietOne quiet]] most of the time, he tends to freak them out when he speaks.
