History Main / PsychoticLoveTriangle

* ''Manga/DeathNote'': [[AmbitionIsEvil Kiyomi Takada]] and [[PsychoSupporter Misa Amane]] vie for the affections of [[ManipulativeBastard Light Yagami]], who is not in love with anyone. Both women qualify as complete yanderes, but [[AGodAmI Light]] is just as crazy, if not more so, than either of them. Misa also seeks the psychopathic [[LightIsNotGood Light]]'s affections and instead finds herself the object of L's attraction - that is, when he's not [[ExaltedTorturer torturing her for information]] (or perhaps especially then?). Then there's the pounds of FoeRomanceSubtext hints that Light may have a thing for L, which may or may not be reciprocated, despite the fact that L knows he's a SerialKiller and Light later [[spoiler:kills him]].

* ''Manga/BlackButler'' features Grell who has an attraction towards numerous characters, especially Sebastian, and especially if [[InLoveWithYourCarnage they are strong]]. Unfortunately for Grell, Sebastian is [[HoYay too focused on and devoted to]] eating the soul of Ciel and is implied to have yandere tendencies towards him. Madame Red had a thing for her sister's lover and went crazy because she was refused and had an accident which made it so she couldn't have a baby. She also flirts with Sebastian and has Grell in love with her and later [[spoiler: killing her]]. Season two has Sebastian acting especially possessive towards Ciel, Claude fighting with Sebastian for Ciel's soul, and Alois is yandere for Claude who [[spoiler: also ends up killing him]] and is jealous of Ciel as a result. Baron Kelvin also was yandere for Ciel as well as Undertaker to a more ambiguous extent. When Baron Kelvin first met a 7-year-old Ciel at a party held by Vincent Phantomhive, he immediately fell in love with him and came to worship him, viewing him as special and beautiful. However, he decided that only special people can touch other special people, and decided to undergo numerous plastic surgeries on his face with parts taken from actual children in order to become more beautiful to suit Ciel.

* ''Anime/ElCazadorDeLaBruja'': Rosenberg and L.A. are yandere for Ellis who [[LesYay has something for Nadie]].

* ''Manga/SeraphOfTheEnd'':
** Ferid acting as a DepravedBisexual yandere towards numerous people like Krul especially, Mika, and Yuu. Mika and Yuu meanwhile are implied to [[HoYay have feelings for each other]], but still do show fair signs of being hetero, which Ferid [[MindGameShip seems to like getting in the way of]] and Mika can be possessive over Yuu. Mika even cuts off Ferid's arm for trying to drink Yuu's blood and later [[spoiler: loses it when Ferid actually ''does''.]]
** There's also Ferid/Mika/Krul. As noted above, Ferid stated he loves Krul, and one can guess he didn't take it well when Krul, um, KISSED MIKA ON THE LIPS. Yeah. This ends on a TearJerker in the Season 2 finale when he subdues Krul and forces her away from Mika, and pretty much [[TraumaCongaLine everything]] that happens to [[TheWoobie Krul]] afterwards is pure TearJerker and NightmareFuel.

* ''Manga/WolfGuyWolfenCrest'' has an interesting (and nightmarish) example in that both Ryuuko and Haguro are Yandere for Inugami's more violent side, and lust after him. They are also in a sexual relationship with each other and think about Inugami while having sex. When the two of them find out that Inugami, who wants nothing to do with either of them, has started developing feelings for [[HotTeacher his teacher Aoshika]]...it gets ugly. [[BreakTheCutie Very]], [[RapeAsDrama VERY]] [[NightmareFuel ugly]].

* Creator/AgathaChristie's short story "Triangle At Rhodes" features two couples: one consists of Valentine Chantry, who is on her [[TheVamp fourth husband]] and seems to have no real regard for his feelings, and her very possessive, jealous husband, Tony. The other consists of Marjorie Gold, a very kind, plain woman who is desperately in love with her husband Douglas, who seems to be infatuated with Valentine (who is returning his feelings). When Valentine is murdered, it looks as though Douglas attempted to kill Tony so he and Valentine could get together, but actually got Valentine instead by pure accident. [[spoiler: In reality, there were actually two love triangles: the fake one (Tony/Valentine/Douglas) and the real one (Marjorie/Tony/Douglas). Valentine and Douglas had no serious feelings for each other, but Marjorie made it look like they did- she wanted to start a relationship with Tony, and they felt that the best way to get rid of their partners would be to murder Valentine and pin it on Douglas, who would subsequently be hanged. Poirot sees through it instantly.]]

* ''Manga/BlackButler'' features Grell who has an attraction towards [[AnythingThatMoves numerous characters]], especially Sebastian, and especially if [[InLoveWithYourCarnage they are strong]]. Unfortunately for Grell, Sebastian is [[HoYay too focused on and devoted to]] eating the soul of Ciel and is implied to have yandere tendencies towards him.

* Website/ThatGuyWithTheGlasses had a [[AllLoveIsUnrequited triangle of rejection]] between WebVideo/TheNostalgiaChick, WebVideo/ToddInTheShadows and WebVideo/ObscurusLupa. The last one didn't do anything, but Todd bordered StalkerWithACrush towards her -- and did [[NoodleIncident weird stuff]] trying to woo her -- and the Chick in turn went as far as kidnap Todd to get his attention. ([[RealitySubtext Todd and the Chick were dating at the time in real life]], and this triangle was abandoned after both ''Webvideo/ToBoldlyFlee'' solved it in-universe and Lupa being MisBlamed on the dismissal of [[WebVideo/TheSpoonyExperiment another reviewer]] made Todd uncomfortable).

[[MadLove Lysa]] [[spoiler: raped Petyr [[DudeShesLikeInAComa whilst he was drugged, delirious and insensible]] twice in the backstory, with him possibly believing she was her sister.]] Petyr, who UsedToBeASweetKid, was left unhinged and bitter after being rejected by Catelyn, so he decided to ''[deep breath]'' [[spoiler:manipulate Lysa into killing her husband and accusing House Lannister of the murder, all in order to draw Catelyn's own husband, Ned, to the DecadentCourt of Westeros, driving a wedge of tension between Houses Stark and Lannister. The end result: Ned was executed for treason, fanning the flames of aforementioned tension, which grew into a spectacularly bloody, continent-wide civil war, leaving thousands dead, the land ravaged and the economy hanging on by a thread just before the start of a winter that could last for generations!]] All of this, just because Petyr DidNotGetTheGirl! The guy takes {{Yandere}} to a whole new level of insanity.
