->''"Now then, Brother, let's get [[MadnessMantra married, married, married, married...]]"''
-->-- '''Belarus''', ''Webcomic/AxisPowersHetalia''

Basically this is when FatherIWantToMarryMyBrother goes horribly wrong. For some reason a person really does want to marry their sibling. Even though they understand [[BrotherSisterIncest what that means]]. This is most commonly depicted in the form of a younger sister who has developed some sort complex or obsessive attraction to her older brother. Perhaps because he [[BigBrotherInstinct protects her]]. Or maybe because he's the only man in her life that she feels safe with.

Sometimes it's suggested that it's not so much that she ''wants'' him. Rather that she doesn't want to lose her brother to all those other girls who are stealing him away from her- so she decides she'll provide her brother with whatever it is he seems to want from other girls. This is still rather {{squick}}y, but might be a little closer to the innocence of FatherIWantToMarryMyBrother. Sometimes might be part of a TokenMiniMoe.

May or may not be a factor with a LittleSisterHeroine.

[[folder: Anime and Manga ]]

* [[{{Yandere}} Belarus]] from ''Webcomic/AxisPowersHetalia'' takes this to [[ComedicSociopathy hilariously]] [[LoveMakesYouCrazy dangerous levels.]] She wants to marry her brother, Russia. She's also Russia's AxCrazy StalkerWithACrush, going so far as to ''hunt him down with knives and break down a door'' when he barricades himself in an attempt to hide from her. South Korea has a similar if less violent complex with his older brothers China and Japan, especially the former, constantly attempting to grope them; they see him as the AnnoyingYoungerSibling and want nothing to do with him, while he refuses to accept that they don't like him.
* In ''Manga/{{Magikano}}'', Maika has a huge complex regarding her big brother Haruo. She's always showering him with affection, hiding in his closet and watching him sleep, trying to bathe him, modelling lingerie for him to see (even wearing it on top of her school uniform to give him a little preview), and attempting to drive away any and all other female attention from him.
* Yoh Takami in ''Manga/DeadmanWonderland'' is called a "sister-complex freak!" by his sister Minatsuki. Given that they're in prison and DW is a {{Seinen}} series, this could be either PetTheDog or {{Squick}} [[spoiler:or both, considering what [[CutePsycho how sadistic his sister is]].]]
* From the Franchise/{{Nasuverse}} is Azaka of ''LightNovel/KaraNoKyoukai'', which is fitting given that [[VisualNovel/{{Tsukihime}} Akiha]] is something of an {{Expy}} of her. Azaka is in love with her brother Mikiya, and left to live with their uncle and attended a different school in the hopes that he would think of her as something other than a little sister.
* Many characters in ''Manga/TenjhoTenge'' remark on Maya's BigBrotherAttraction regarding Shin. It's almost to the point of BrotherSisterIncest.
* In ''Anime/RevolutionaryGirlUtena'', [[AnnoyingYoungerSibling Nanami]] lets everybody know that her big brother Touga is the best. She is so obsessed with being onii-sama's sole target of attention that she [[KickTheDog got rid of his kitten]] and humiliates a girl from her GirlPosse. After realizing what a ManipulativeBastard her brother is, we see how her hopeless devotion to him is actually quite tragic.
* ''Oniichan Control''. The little sister ''openly admits'' to people she ''barely knows'' how in love she is with her big brother. Played for some combination of horror and laughter at how over-the-top it all is.
* The ''AudioPlay/YandereNoOnnaNoKo'' Drama CD series is based on this + AxeCrazy. The listener is in the position of "onii-chan" (the big brother), and gets to listen as the various little sisters explain in detail ''just'' how [[LoveMakesYouCrazy crazy]] [[IfICantHaveYou they are]].
* Might be the case with Kotomi in ''Manga/SeitokaiYakuindomo''. She likes [[InvokedTrope invoking]] BrotherSisterIncest (especially in the {{yonkoma}}), Episode 12 has her admitting that she had an incestuous dream, and she also mentions that she and her brother Tsuda sometimes get mistaken for a couple, which she plays up. When her friend notes that it's sometimes hard to believe the two are related because of their very different personalities, Kotomi [[http://www.mangafox.com/manga/seitokai_yakuindomo/v03/c007/6.html gets excited]] and interprets the comment as a possibility that they might be NotBloodSiblings.
** Kotomi also has no problem [[http://i1118.photobucket.com/albums/k606/Ilya-SDNW4/KotomiStrip.jpg taking her clothes off in front of her brother]] and once proudly mentioned to the other girls that he's also "impressive down there," which has him wondering as to when the hell she managed to sneak a peek.
* ''Manga/ImoutoWaShishunki'' (My Little Sister is Going Through Puberty), made by the same mangaka as ''Manga/SeitokaiYakuindomo'', has a little sister who makes extremely perverted statements around her big brother and has constantly hinted in a blatant manner that she wants to do more than sisterly things with him.
* Although Haru and Sora from ''VisualNovel/YosugaNoSora'' are actually the same age, they are commonly referred to as 'older brother' and 'younger sister', and Sora otherwise exhibits this trait very well. Haru is [[{{Twincest}} a bit more receptive]] than most examples here, though.
* In ''Manga/WitchCraftWorks'', Takamiya's sister has a [[EveryoneCanSeeIt blatant crush]] on him, but she's in denial, claiming her actions are just her right as a little sister. HilarityEnsues.
* ''Anime/CodeGeass'' has it's own page on [[IncestSubtext/CodeGeass the incestuous subtext between siblings]], with Nunnally and Lelouch being the most obvious example.
* ''Manga/UruseiYatsura'': Asuka Mizunokuji, younger sister of baseball-nut Tobimaro and his rival Mendo's [[ArrangedMarriage fiancee]], was raised in isolation due to family tradition and as a result she's terrified of the mysterious, monstrous ''man-folk'' (not that she should be, she's one of the [[DoesNotKnowHisOwnStrength strongest human characters]] in the series). Because she was told that "big brothers are the best kind of men", Asuka fell in love with Tobimaro, who is squicked out of his mind but can't do a lot about it because Asuka is genuinely ([[ComedicSociopathy if hilariously]]) screwed-up due to how... specially she was raised. [[spoiler:She eventually ''does'' fall for Mendo... after it's explained that ''he's'' a big brother too.]]
* ''Manga/{{Freezing}}'': She calls him "Onii-sama" [[spoiler: but Ouka Tenjouin is actually Kazuya's cousin]] and she's gonna marry him [[PluckyGirl no matter what]]. In an unusually assertive move the NiceGuy [[spoiler: Kazuya]] tells her to her face, in front of her team ''and'' his love interest (and her rival) [[spoiler: Satellizer]], that he doesn't love her like that, he doesn't want to be their grandfather's "toys", and he wants her to be happy. The girl's response is that [[AnguishedDeclarationOfLove she does love him]], he ''will'' make her happy, and most importantly [[ArrangedMarriage their grandfather's word is law]].
* ''LightNovel/OniiChanDakedoAiSaeArebaKankeinaiYoNe / [[ExactlyWhatItSaysOnTheTin He's my brother, but as long as we're in love it shouldn't matter, right?]]''
* Miyuki in ''LightNovel/MahoukaKoukouNoRettousei'' is practically clinging at her brother almost all the time.
* In ''LightNovel/SakurasouNoPetNaKanojo'', Yuko seems to have it towards her big brother Sorata.
* ''Manga/KoiKaze'': "I do NOT have a brother complex!" Ah, but she does.
* The OAV adaptation of the hentai game ''Ko-ko-ro...'' features quite the literal example, as Asuka Kuonji treats her brother, Souji, as if he were her boyfriend instead of her brother. When they are out in public together, she is affectionate and clingy with him, which, of course, is shocking to everyone around town (who apparently know that they are siblings). [[BrotherSisterIncest Souji and Asuka have sex regularly]], until he begins having a relationship with his teacher, Mizuki. Asuka, of course, is not happy with this development.
* In ''LightNovel/{{Oreimo}}'', Kirino always wanted to marry her brother since she was a little girl. [[spoiler: They eventually start dating and hold a fake wedding. They do break up and say they will be normal siblings though it is implied that they are still secretly together at the end of the novel]].
* Diana in the first series of ''Franchise/{{Jewelpet}}'' has a pretty obvious, but not too explicit, crush on her brother Dian. She fangirls extensively over him and wistfully fantasizes about living like a married couple. Dian never responds to this.

[[folder: Film ]]

* Jackie from ''Film/TheHouseOfYes'' goes beyond finding her brother attractive. The two of them actually had an affair in the past.

[[/folder]]

[[folder: Literature ]]

* Done in the ''Literature/{{Darkover}}'' series with ''Stormqueen!'' Everyone's already disturbed by the father suggesting he marry off his daughter to her half-brother as a way to resolve an inheritance crisis, but then Dorilys starts to get into the idea, and Donal gets used to it...

[[/folder]]

[[folder: Live Action TV ]]

* In ''Series/TheBorgias'', Lucrezia and Cesare seem a little too close, with her saying that she will never love her husband as much as she loves him. Cesare seems to reciprocate, saying that if her husband proves "ungallant", "I will cut out his heart with a dinner knife, and serve it to you", in a very low, breathy whisper, while nearly giving her a HeadbuttOfLove, and this is just after he has carried her up to her bed on her wedding day. [[TruthInTelevision Given the historical characters they're based on]], though, it would be surprising if there ''wasn't'' a lot of incestuous implications in the show.
** In Season 3 Episode 3 [[spoiler: they explicitly consummate their attraction, finally moving away from the "subtext" and into straightforward "text"]].
* A two-part episode of ''{{Series/CSI}}'' focused on this. In the first part, she manages to create enough doubt that her brother committed a murder (that he actually did commit) at her own expense, but also leaving enough holes that she couldn't possibly be the murderer either. In the second episode, she [[MurderTheHypotenuse murders his girlfriend]] and frames him for it, partly to get rid of the obstacle and partly because she figures that by visiting him in prison every day, he'll fall in love with her.
* In ''Franchise/{{Degrassi}} Takes Manhattan'' there is a rivalry between Holly J. and Fiona for the affections of Declan who is Fiona's twin brother and Holly J.'s boyfriend. Fiona's attitude is "Boyfriends are temporary. Brothers are forever." She has an emotional dependency on Declan and couldn't stand to come second in his life which she makes clear to a whole party of people.

[[/folder]]

[[folder: Music ]]

* The song [[http://www.youtube.com/watch?v=EgHcCjF8V1g "Ark"]] by Sound Horizon implies this by naming the two characters involved [[AltumVidetur "Frater" and "Soror"]]. [[AxCrazy It ends badly.]] [[MindScrew Or does it?]]

[[folder: Mythology and Religion ]]

* In Literature/TheBible, Dinah either has an affair with, or is raped by, a man called Prince Shechem, who then agrees to marry her. However, two of Dinah's brothers, Simeon and Levi, instead go to war against Shechem and kill him. In one Jewish legend Dinah, angry and fearing that she was DefiledForever without her fiancÚ, demands that Simeon marry her. He formally does but never sleeps with her. (This is the interpretation of a later verse, when it mentions "Saul, the son of the Canaanite woman" [Dinah] being a member of his household.)
* In one Arthurian legend a princess falls in love with her brother. A demon offers to make the prince love her back, as long as the princess and demon sleep together. Instead the princess gets pregnant and the demon turns her love for her brother into hatred, so that she accuses him of raping her. He is executed, but first declares his innocence and predicts that his sister will give birth to a monster. Indeed, her child winds up being the Questing Beast.

[[folder: Video Games ]]

* Albedo from ''VideoGame/{{Xenosaga}}'' has a ''huge'' BigBrotherAttraction with his [[{{Twincest}} twin]], [[spoiler: Junior]]. He becomes something of a StalkerWithACrush towards him, and was shown to have gone [[AxCrazy crazy]] due to the revelation that he wouldn't be able to stay together with him forever.
* The original version of the bishoujo game ''Ko-ko-ro...'' depicts an incestuous relationship between Souji Kuonji and his sister Asuka. Asuka seems more invested in the relationship than Souji; she even fantasizes about marrying Souji and having sex with him before they even leave the church where they were wed.
** The multiple depictions of incest in ''Ko-ko-ro...'' within and outside of the Kuonji family caused enough of an uproar that the game was banned from the Japanese market. An unauthorized edited version was later released, in which Asuka and Souji were no longer presented as blood siblings, but instead as stepsiblings. This was further edited when the game was adapted into a 2-part OAV; here, Souji is shown in flashback to have been an orphan adopted (and later molested) by the Kuonji family.
* In ''VideoGame/BlazBlue'', it sure sucks to be in Ragna's shoes for having a younger brother Jin who not only wants to kill him, but was also obsessively lust after him to the point he will inflict physical harm or even kill those who he deems will take his "niisan" away from him e.g. [[spoiler: Saya and Noel]]. However, it's also implied (to the point that it's all but outright stated) that Jin's obsession isn't natural: [[spoiler:it's a product of being utterly {{Mind Rape}}d by the BigBad, Yuki Terumi, who ''needs'' Ragna to hate him as much as possible for as many reasons as possible so that he can continue living.]]

[[/folder]]

[[folder: Visual Novels ]]

* Never actually happens in ''VisualNovel/LittleBusters'', but Kyousuke jokingly references this trope a couple of his nicknames for when Rin loses against him:
-->'''Kyousuke:''' This will be your name from now on: 'Her first crush looked like her older brother!'
-->'''Rin:''' ''I don't want that, moron!''
* Akiha from ''VisualNovel/{{Tsukihime}}'' is attracted to her older brother, though she usually hides it under [[{{Tsundere}} antagonistic behavior]]. [[spoiler:Though they're NotBloodSiblings.]]
** Notably, she's the only heroine with endings that has no "Good End". [[spoiler:Either Shiki dies (the True End), or she becomes a vegetable (the Normal End)]]. A side-story in KagetsuTohya following Akiha's True End reveals [[spoiler:that he is still alive, though]].
* Ange really seems to border on this in ''VisualNovel/UminekoWhenTheyCry'', which is parodied in the side stories of ''Tsubasa'' and the various manga omake. In the manga of Episode 4, she makes a complete fixation on Battler whenever she remembers her family. The implications are probably attenuated by the fact that Battler left the family shortly before her birth (and, indirectly, ''because'' of it, though he still adored her) and only visited her on her birthdays before coming back to the family [[spoiler:and [[DeathOfPersonality "dying"]] in the Rokkenjima incident]], so they didn't have much of a brother-sister relationship (she was only 6 years old at the time). There is also the fact that they she's "only" his half-sister. [[spoiler: Until we learn that [[SwitchedAtBirth Kyrie is Battler's real mother]], so they are actually fully blood-related.]]

[[folder: Web Original ]]

* Sayu in the original [[WebVideo/DeathNoteAbridgedTioHAndDargonakis Death Note Abridged]] by [=TioH=] and Dargonakis. Who isn't particularly subtle about it.

[[/folder]]

[[folder: Western Animation ]]

* On ''WesternAnimation/PhineasAndFerb,'' this is one interpretation of [[EnfantTerrible Suzy]] to her older brother [[SingleWomanSeeksGoodMan Jeremy]]. If nothing else she seems to fit the "doesn't want to lose him" model, as she's fiercely jealous of [[ButtMonkey Candace]] becoming his new "favorite girl".
* A ''really'' disturbing example comes from ''WesternAnimation/AvatarTheLastAirbender'' with [[ManipulativeBastard Azula's]] relationship to [[AntiVillain Zuko]]. She has quite a lot of NoYay with pretty much everyone she encounters, but that infamous scene where Zuko confronts her about one of her latest schemes and she answers by acting as close to TheVamp as a PG show could get really drives the point home. There is also something extremely {{Yandere}}-ish in her VillainousBreakdown. This is an unusual example of this trope because they frequently fight each other with the intention of doing serious harm/killing each other, and despite being younger, she is the stronger one in terms of [[MagnificentBastard intelligence]], [[MyKungFuIsStrongerThanYours fighting skill]] and [[DaddysLittleVillain her father's affection]], and thus her IncestSubtext-laden interactions with Zuko have her occupying the creepily possessive and domineering position of a DomesticAbuser.
