History Yandere / AnimeAndManga

** [[spoiler: Lately, it seems that Leo may be this for Elliot, as well.]]

*** "Alice, don't cry. Whoever makes you sad, whoever hurts you, I will destroy them. All of them...With my own hands!"
--> He was already yandere for her from back when he almost [[spoiler: tore apart the Abyss in order to get rid of everything that hurts Alice and causes fear within her, including [[LoveMakesYouCrazy Alice herself]]]].

* Momoko from ''SumomomoMomomo'' does anything and everything to impress and mate with her uninterested love interest, Koshi, including fetching a frisbee like a dog, preparing dinner on her body, and preforming on his behalf towards his psychotic gym teacher. Her relentless loving insanity is not a backdrop or a side trope, it is pretty much the basis of the entire series.
** Momoko's all "dere" and no "yan" however so I really don't think she counts. She has never tried to kill any of the love rivals and when Koushi pays attention to other women, she is merely sad, though tearfully states "I won't lose". Momoko also admits to Iroha, (her best friend who also loves Koushi)that she's well aware that Koushi has never admitted that he loves her and she is merely fantasizing about their mutual love all by herself, therefore Iroha's crush on him does not upset her the least bit. No, Momoko is EXTREMELY far from being called "yandere"; she is anything but.

* [[spoiler:[[LoveMakesYouCrazy Ijuin Nozomu]]]] of SteppingOnRoses gradually changes from PrinceCharming and TheWhitePrince to this.

--> He was already yandere for from back when he almost [[spoiler: tore apart the Abyss in order to get rid of everything that hurts Alice and causes fear within her, including [[LoveMakesYouCrazy Alice herself]]]].

** And Oz for Alice [[spoiler: as of Chapter 57]].
--> "Alice, don't cry. Whoever makes you sad, whoever hurts you, I will destroy them. All of them...With my own hands!"

* Akari from ''GirlGotGame'' is Type 2 for poor [[SweetPollyOliver Kyou]]. She'd never try to hurt "him", no matter how much "he" refuses, but she is willing to ''threaten suicide'' for a date.

* Hikaru from ''GirlGotGame'' is Type 2 for poor [[SweetPollyOliver Kyou]]. She'd never try to hurt "him", no matter how much "he" refuses, but she is willing to ''threaten suicide'' for a date.

** She's been getting worse too! Belldandy has stood up to Hild, the ruler of demonkind over Keiichi and in the latest Manga arc [[spoiler: Tamiya and Otaki are taken over Hagall and attack Keiichi. Belldandy STRIKES THEM DOWN with an attack spell. No warnings, no crying out to them to remember themselves, no 'I can't attack our friends', they get ZAPPED, instantly.]] Belldandy is in no mood to faff around when it comes to Keiichi anymore.

** Volume 9 of the novel reveals that [[spoiler: Izaya]] is a yandere for [[spoiler: Shinra]], in the rare not romantic mode. However, this is explained because [[spoiler: Shinra is his [[MoralityPet only friend]] and the only one that walked up to him and befriended him as well as being one of the few people that could read him easily. The stabbing incident was actually Shinra [[TakingTheBullet taking a knife wound for Izaya] when a student called Nakura demanded that Izaya give him the money that he lost when gambling on him. In exchange for [[SilentScapegoat lying]] saying that Izaya himself [[KicktheDog stabbed his only friend]] Izaya swears that Nakura will regret this for the rest of his life. In other words, his motivation for becoming an information broker is hinted to be because of Shinra.]]

** [[spoiler: Semi-subverted in episode 8. She continues to fall and even seems to kill two misogynistic guys, and later turns into a Witch. But Witch!Sayaka (or better said, Oktavia Von Seckendorff) did not attack her crush Kamijou nor her apperent rival Hitomi, limiting herself to create a witch's barrier reflecting her desire to be loved and noticed by Kamijou: the barrier in itself resembles a music theater, one of her [[{{Mooks}} familiars]] looks like a violinist (just like the guy), and there are several posters on the wall that say "look at me, look at me, LOOK AT ME!"]]

* The ''StrikerS'' {{yonkoma}} show Caro as [[http://i18.photobucket.com/albums/b122/Chryssalid/Nanoha/Strikers%20Nano/strikers_nano090.png just a little too possessive]] toward her "husband," Erio.

** Rewind a to the second episode: you get Dan Eiga's girlfriend, Miyazaki "Miya-Miya" Miyako.

* In the shoujo manga ''HadashiDeBaraWoFume'', [[spoiler: Nozomu was originally a sweet gentleman who had been the merciful one that donated money to Sumi when her kid brother got really sick.]] However, his character becomes increasingly possessive and eventually an out-and-out Yandere for her. He eventually goes so far as to try to rape her, only to decide to [[spoiler: commit a double suicide with her when the place gets set on fire.]]

* Belldandy from ''AhMyGoddess'', has been known to cause everything from minor explosions to freak weather changes whenever someone tries to go after Keiichi, and that's when she's trying to hold her Yandere tendencies back. It's to the point that other goddesses know to duck for cover when they see some girl try to get sweet on Keiichi.

** In the first season finale, [[spoiler: when Zagato is defeated and killed by the Knights, Princess Esmeraude's [[BreakTheCutie last streak of sanity disappears.]] She then unleashes her powers fully and battles the Knights herself, loudly calling them out for murdering Zagato and going hell-bent for revenge. After her subconscious appears before the Knights and explains what happened (and how Esmeraude wanted them to kill ''her''), the girls have to battle the now psychotic princess and kill her.]] In the OVA's, the poor lady is [[TheOphelia even more unhinged]]: [[spoiler: Emeraude pines for an already dead Zagato and throws herself at his feet, as he still sits on his throne.]]

* It looks like [[spoiler: Sayaka Miki]] from ''PuellaMagiMadokaMagica'' is showing signs of this, having broken down as an after effect of her BreakTheCutie side. Currently it's less about possessiveness or obsession, but more about [[spoiler: LaughingMad at some point, fighting more and more recklessly, and going AxCrazy when the witches come in episode 7.]]
** [[spoiler:Semi-subverted in episode 8. She continues to fall and even seems to kill two misogynic guys and later turns into witch. But she did not attack her crush nor her apperent rival.]]

** [[spoiler:Semi-subverted in episode 8. She continues to fall and even seems to kill two misogynic guys and later turns into witch. But she did not attack her crush nor her apperent rival.]]

** [[WhiteHairedPrettyBoy White-haired]] Tohma Seguchi is obsessed with Yuki too, to the point where he pushes Taki Aizawa in the path of a car (which [[SchrodingersCat runs him down in the manga]]) when he threatens to uncover Yuki's past and tells Shuichi that if he doesn't break up with Yuki, he'll fire his band from NG Studios -- all without losing his smile. Oh, and he's married to Yuki's older sister Mika. Take from ''that'' what you will.

** Confirmed in episode 8, when [[spoiler: she refuses to useGrief Seeds to purify her own Soul Gem, then at the end of the episode says that BeingGoodSucks, and transforms into a Witch.]]

* Gilbert from ''KazeToKiNoUta''. Make sure to befriend Auguste at your own risk.

** More recently, it's revealed that Ukraine is ''also'' one. Her character song with Belarus pretty much exposed how she's just as [[{{Understatement}} obsessed]] with her brother as her sister.

** Elsa [[spoiler:kills first her Handler and then herself, because he never returned her affection.]]

* ''{{Kuroshitsuji}}'''s version of [[spoiler: Queen Victoria, to the point where she merges her body with that of her dead husband.]]
** [[spoiler:The actual Queen, though, [[http://en.wikipedia.org/wiki/John_Brown_(servant) probably not so much]].]]

** In the first season finale, [[spoiler: when Zagato is defeated and killed by the Knights, Princess Esmeraude's [[BreakTheCutie last streak of sanity disappears.]] She then unleashes her powers fully and battles the Knights herself, loudly calling them out for murdering Zagato and going hell-bent for revenge. After her subconscious explains what happened (and how Esmeraude wanted the girls to kill ''her''), the girls have to battle the now psychotic princess and kill her.]] In the OVA's, the poor lady is [[TheOphelia even more unhinged]]: [[spoiler: Emeraude pines for an already dead Zagato and throws herself at his feet, as he still sits on his throne.]]

** And then there's [[spoiler: Asayo, Katsuragi's much abused wife. After Souma immobilizes Katsuragi with poison, brutally [[TheReasonYouSuckSpeech humiliates him]] and definitely abandons him, she ''sets her abusive husband on fire''.]]

* Male example: Cho Hakkai from ''{{Saiyuki}}''. His [[{{Twincest}} twin older sister/lover]], Kanan, was [[BreakTheCutie kidnapped, gang-raped, forcibly impregnated]] ''[[BreakTheCutie and]]'' DrivenToSuicide by demons; in his quest to find her, he murdered 1,000 demons of the same clan, another clan responsible for her kidnap and transportation, ''and'', in the manga, the ''entire'' village that stood around and didn't stop the poor girl's kidnapping. ''But wait,'' there's more! When confronted by a survivor who wants revenge, Hakkai freaks him out by offering his eye as penance---by '''[[EyeScream plucking it out of the socket]].''' And he runs into this survivor while muttering about wishing he could have Kanan's corpse. The series proper, starting a few years after this incident, usually lets him off with being a TeamMom with shades of creepy StepfordSmiler, but is it any wonder the other characters are ''freaking terrified'' of Hakkai?

* ''PrincessPrincess'' has Sayaka Kouno, the cousin of main character Tooru Kouno. Tooru's parents died in an accident and Sayaka's parents adopted him and Sayaka and Tooru became close when they were kids. However, while Tooru just thinks of Sayaka as a sister, Sayaka always had stronger feelings for Tooru than just that of a sister to a brother. She is quite insistent about them getting married one day, despite Tooru's reluctance to the idea and is shown to have an unhealthy obsession towards him. This is to the point that she once shoved one of Tooru's previous girlfriends down a flight of steps out of jealousy, literally stalks Tooru, and keeps tabs on his phone calls. Her fragile grip on reality was damaged by Yuujiro's claim that he and Tooru are lovers- and that Tooru is not interested in girls. (He kissed Tooru in front of Sayaka in order to get her to leave Toru alone when she showed up to harass him.) She eventually tried to kill herself by jumping off a cliff saying that it would be too painful for her to live if Tooru didn't return her feelings. It's only when Tooru slaps her and has a long talk with her that she decides to back off.
** She also has a habit of stabbing Tooru's girlfriends with scissors.

* Really played for laughs for Akira Kogami in ''LuckyStar''.

** Volume 9 of the novel reveals that [[spoiler: Izaya]] is a yandere for [[spoiler: Shinra]] but not in the romantic sense. However, justified because [[spoiler: Shinra is his [[MoralityPet only friend]] and the only one that walked up to him and befriended him as well as being one of the few people that could read him easily. The stabbing incident was actually Shinra taking a knife wound for Izaya when a student called Nakura demanded that Izaya give him the money that he lost when gambling on him. In exchange for [[SilentScapegoat lying]] saying that Izaya himself [[KicktheDog stabbed his only friend]] Izaya swears that Nakura will regret this for the rest of his life. In other words, his motivation for becoming an information broker is hinted to be because of Shinra.]]

* Konuma Ryuuko of ''WolfenCrest''. She's a nymphomaniac middle-schooler with what appears to be [[BrokenBird profound psychological damage]] from repeated rapes in her past, but she's such a nihilistic sociopath that even this isn't enough to make her sympathetic. Notable acts include breaking into the protagonist's apartment to masturbate and (unsuccessfully) seduce him, climaxing on a school rooftop during a bloody shooting, and thinking madly about raping the protagonist while having sex with gigantic and bloody terrifying school gang leader [[CompleteMonster Haguro Dou]]. Who, incidentally, is the only man who has ever slept with her without ''dying'' [[DeathBySex shortly afterwards]]. Originally, she came off as one of the manga's more playful and sympathetic characters; now, she's pretty much a fountain of FanDisservice and downright [[NightmareFuel creepiness]].
** [[spoiler: The abovementioned Haguro Dou]] takes it BeyondTheImpossible towards the protagonist. He cuts himself all over his arm and carves the word "Inu" onto his hand and has an orgasm while thinking about Inugami when having violent sex with his girlfriend. He beats down, craps on and ''rapes'' [[spoiler: his own subordinate, Chiba]] and tears out his tongue as he's kissing him. The poor guy gets put into the hospital because Haguro beat him to the point that [[HighOctaneNightmareFuel all his organs ruptured and his bones break]] and he ends up dying. [[spoiler: Though he gets better]]. All because Chiba ran into the protagonist on the street and talked to him for, maybe, 15 minutes, when [[spoiler: Haguro]] wasn't around. He also rapes [[spoiler: Aoshika]] while recording it so that Inugami can see, practically talking to the camera (and, therefore, to Inugami) through the entire thing hoping to provoke Inugami into coming back to him.

** Fukiko has shades of this, in another way. Rather than turning her disappointment against the object of her affections, Henmi, she turns it against others. Also, the room at her summer house is full of creepy dolls and obsessively arranged items of memorabilia from the day she first met her crush Henmi, which she has since kept completely unchanged for six years and forbids anyone else to enter.
* ''[[{{Ptitlecr52i41p}} Zetsuai 1989]]'' is all about this trope.

* {{Shiki}} has Megumi who started as a {{Stalker With A Crush}},[[spoiler: but after turning into a vampire murders her crushes best friend, because she's jealous of how close they are]].

* Giriko from ''SoulEater'' for Arachne. After Arachne's death Giriko had a VillainousBreakdown and proceeded to try to rape Maka and then attempt to kill both her and Soul. [[spoiler:But Soul kicked Giriko in the head (we wouldn't be shocked if it caused further brain damage) before he could even touch Maka, so no worries.]]

** Confirmed in episode 8, when [[spoiler: she says that BeingGoodSucks, and transforms into a Witch.]]

* [[spoiler:Akito Sohma]] from ''FruitsBasket''. The first has a pathological fear of being left alone due to ParentalAbandonment ''and'' an EvilMatriarch mother's horrendous psychological abuse [[spoiler: which translates into horrible manipulations and wild mood swings]]

* It looks like [[spoiler: Sayaka Miki]] from ''PuellaMagiMadokaMagica'' is showing signs of this, having broken down as an after effect of her BreakTheCutie side. Currently it's less about possessiveness or obsession, but more about [[spoiler: LaughingMad at some point, fighting more and more recklessly, and going AxCrazy when the witches come in episode 7.]]
