History BrotherSisterIncest / AnimeAndManga

* ''Manga/KoiKaze'' is a case of this trope being [[DeconstructedTrope deconstructed]] and PlayedForDrama with two blood siblings who haven't seen each other since the brother was 18 and the sister was only 5 when their parents divorced and their mom took sole custody of the sister, and as a result, the UsefulNotes/WestermarckEffect didn't take hold. The series has a more harrowing portrayal and doesn't gloss over just [[InconvinentAttraction how painful and frustrating]] such a situation would be for both parties involved.

* In the Manga for ''Manga/ElfenLied'', [[spoiler: this is the entire reason Lucy/Nyuu/Kaede's half-brother was born. Kakuzawa wants him to mate with Lucy/Nyuu/Kaede and procreate more Silphelits.]]

* ''Anime/MawaruPenguindrum'''s first episode has Kanba Takakura kissing his younger sister Himari after she's resurrected and while she's sleeping. It hasn't been referred to later, though. [[TemptingFate Let's give it time.]]
** It's given a rather philosophical twist in this series; Kanba's InternalMonologue in the scene revolves around [[ScrewDestiny defying fate]] and the animalistic [[ArcWords survival strategy]] to determine one's free will. Basically, doing something that your very biology abhors is used as a sign for freedom of choice.
** In the Penguindrum novel, the scene where a posssessed Himari pulls something out of Kanba's chest ([[spoiler: his life energy]]) is a little more suggestive than in the anime version. Not to mention, in the anime the kiss scene went into fade to black when Kanba's lips were milimeters away from Himari's. In the novel? It's described quite in detail.
** Taken further in episode 12, where [[spoiler: before dying again (temporarily), the possessed Himari shares a last goodbye with Kanba. When they're the only ones in her Dream World. [[http://imageftw.com/uploads/20110929/1317318196481.jpg While she's pretty much naked except for her boots and the Penguin Hat, and Kanba's chest is exposed due to self-inflicted Clothing Damage]]. [[DoesThisRemindYouOfAnything A sexual encounter wouldn't have been out of place]].]] Though there ''may'' be a twist here, [[spoiler: with the sex-charged interaction itself being more in between Kanba and the ''possessor'', the Princess of the Crystal, rather than between him and Himari. [[MindScrew It's... hard to tell]].]] It happens again in episode 17, when [[spoiler: Himari/the Princess [[http://i42.tinypic.com/2wp8c51.jpg strips again]], [[CooldownHug cradles]] [[http://i39.tinypic.com/2em0gih.jpg a depressed Kanba to her/Himari's bare bosom]], and pretty much [[http://i40.tinypic.com/243mely.jpg throws herself into his arms]]. Again, not clear who is who here, but still. . .]]
** Aaaand then... [[spoiler: it's ''subverted''! Himari and Kanba are NotBloodSiblings. Episode 19 explains that Himari was adopted into the Takakura family after she was rescued from a plance named the Child Broiler... and her savior was her and Kanba's brother, Shouma. Kanba himself is adopted too; he and Shouma relied on each other to survive, but he only felt truly as a Takakura when Himari welcomed him into the family.]]
** Then finally reintroduced in the form of {{Twincest}} when [[spoiler: Masako, Kanba's stalker and apparently jealous ex, turns out to be his biological twin sister, and Masako and Kanba were both well-aware of their relationship the entire time. Having physically assaulted and mind-wiped the rest of Kanba's ex girlfriends since she didn't see them as good enough for him, Masako ultimately turns her sights on Himari, whom she sees as both familial and romantic competition, but later sets it aside when Kaba pulls a FaceHeelTurn.]]

* In ''Anime/ShinkonGattaiGodannar'', English pilot Knight Valentine will flirt with any female in sight, much to the consternation of Ellis, his sister and partner, who thinks he doesn't notice her. But if [[spoiler:the way he looks at her swimsuit-clad form and the fact that he sees Ellis' face when an amnesiac Mila is hitting him with CharmPerson are any indication, he ''does'' notice her in that way.]]

* ''Manga/UchiNoMusumeNiTeODasuNa'': In chapter 9, Artemis challenges her older sister, Athena, to a duel to decide whether she and her daughter would have to [[spoiler: return to their home planet with her]]. The match is even, until Athena catches Artemis off-guard by suddenly tongue kissing her. Then she capitalizes on Artemis' shame and confusion by fingering her, and finishes her off by 69ing with her in midair. Artemis [[BeatThemAtTheirOwnGame tries to retaliate]], but she climaxes first. She concedes the match, but still [[WhatTheHellHero calls Athena out]] for using such [[DefeatByModesty underhanded tactics.]]

* ''Manga/KoiKaze'' is a case of this trope being [[DeconstructedTrope deconstructed]] and PlayedForDrama with two blood siblings who haven't seen each other since the brother was 18 and the sister was only 5 when their parents divorced and their mom took sole custody of the sister, and as a result, the UsefulNotes/WestermarckEffect didn't take hold. The series has a more harowing portrayal and doesn't gloss over just how painful and frustrating such a situation would be.

* ''Manga/KoiKaze'' plays this trope straight with two blood siblings who haven't seen each other since childhood.

* Anime/FromUpOnPoppyHill uses it as a ZigZaggedTrope when Umi and Shun fall for each other, find out they're related, resolve to continue the relationship anyway, then find out they're definitely ''not'' related. As far as they knew, they definitely fell into the trope for the few hours between deciding to continue and finding out the truth, though nothing physical happens during that time.

* ''LightNovel/{{Oreimo}}'': Whether or not siblings Kirino and Kyosuke do or don't have a sexual attraction/hidden desire to each other is the ElephantInTheLivingRoom of the series. The anime adaptation leaves it hanging; the last chapter confirms it.
* ''LightNovel/EromangaSensei'' from the same writer/illustrator team makes it clear that step siblings Masamune and Sagiri are attracted to each other almost from the outset. Masamune straight up declares his love in episode 3, though neither pursues it in part due to hang ups from their loss of family members - each is an orphan when the series begins, and he hadn't seen her in the 2 years since their parents died and she became a hikkikomori.

** [=DiC=], perhaps as bowdlerization, had Crimson Rubeus refer to his four main female minions as sisters. He may have been referring to their name as a group, the Phantom Sisters, but it's suspicious suspect when you realize most of them are attracted to him.

* ''LightNovel/SisterPrincess'' and its "sequel" series, ''Anime/SisterPrincessRepure'', both have incestuous subtexts, but the subtext surfaces clearly in ''Repure'': in the very first episode, Karen recounts how she decided that she would be her brother's bride, despite society's disapproval of such a thing. In the original series it is less visible, although still present -- one sister (Chikage) was [[spoiler:Wataru's lover in a [[{{Reincarnation}} previous life]] ]], Sakuya openly flirts with him (Rin Rin and Mamoru are more subtle hiding their flirting under the disguise of admiration for their Brother), and all twelve spend one episode making mock wedding dresses so they can play at being his "bride".

* [[Franchise/{{Nasuverse}} Nasu Kinoko]] ''loves'' this trope:
** In ''VisualNovel/{{Tsukihime}}'', Shiki's sister Akiha has a very possessive crush on him. Parodied in numerous doujinshis and official [[{{Omake}} omakes]], including one where Ciel points out the hopelessness of the crush. Shiki's feelings are purely platonic. And a large part ''sheer terror''--Akiha is '''[[{{Tsundere}} tsun]]'''[[{{Tsundere}} dere]] at best and {{yandere}} at worst. Of course, [[spoiler:they ''are'' NotBloodSiblings, and]] Akiha does have her own path in the VisualNovel.
*** Though they never did anything incestuous, [[spoiler: SHIKI]] hints many times that he has romantic interest in his sister [[spoiler: Akiha. Too bad all she thinks about is her other "brother"]].
** On that note, Azaka from ''LightNovel/KaraNoKyoukai'', who can be considered prototype of Akiha above, also loves her brother deeply, to point where it gets in the way of her becoming friends with the series heroine Ryogi Shiki. Her love may not be the same in nature as Akiha's but since she and her brother were used as a strong basis for Akiha and Shiki, it is likely that the "love for my brother" was carried over as well.
* The ''Manga/{{Spiral}}'' manga has a variation: Ayumu was in love with his sister-in-law even before [[TheMinnesotaFats his brother]] married her, and lived with her after he disappeared. Also, [[spoiler:since all of the Blade Children have the same father, Kousuke and Ryoko's relationship, despite growing up as childhood friends rather than siblings, is incestuous. Kousuke specifically asks Ryoko not to call him 'big brother,' saying that he wants to be able to dream of being with her]].
* All but expressly stated in ''Edens Bowy'' between tragic siblings Wietoo and Hairra. Initially averted when Hairra actually tried to pair her older brother Wietoo together with her best friend Fennis in an effort to repress her own incestuous feelings, but it failed anyway due to irreconcilable differences of ideology between Wietoo and Fennis, who also noticed Hairra's disturbingly excessive attachment to her sibling. Eventually the siblings get together when Hairra decides to acknowledge her feelings upon realizing that no one would love her brother as much as she did (which led to a falling-out with Fennis) and Wietoo also realizing that only Hairra would ever accept all of him, including his controversial views on the creation of sentient A.I. Hairra is soon killed tragically sometime afterwards when Wietoo's first android goes berzerk, and she is reborn as his personal gynoid weapon/bodyguard. Later, when they are both killed at the series end, they are reborn together as sentient programs together roaming forever their world's version of the internet.
* Aono in ''Manga/{{Sola}}'' is obsessed with her (younger, for a change) brother Yorito [[spoiler:to the point of creating a copy of him that took enough power to leave her bed-ridden for years]].
* It is heavily implied in the ''Manga/ShadowStar'' anime that the bully Aki Honda and her older brother Yasuhito have a ... rather intense relationship. It's downright spelled out in the manga. [[spoiler: So much that Aki is once shown straddling Yasuhito while practically naked. Then, Oni shows up, kills Yasuhito by smashing his head on the wall, and rapes and kills Aki as revenge for what they did to his master, Hiroko.]] Said scene is censored in many countries in the world (even the Japanese version got censored retroactively) and spelled the end of the series' publication in many others.
* Renhou and his older sister Miiru in ''Manga/FushigiYuugi''. [[spoiler: In fact, their incestuous relationship got them killed by their people, and they go to the BigBad Tenkou in hopes he'll help them stay together.]]
* In the first episode of the ''VideoGame/VoltageFighterGowcaizer'' OVA, the Villains Of The Week were an incestuous set of twins (who were empowered by the BigBad to save the dying sister) who merged into a gestalt monster "powered by love".
* ''Anime/InfiniteRyvius'': [[spoiler:We eventually discover that Ikumi had fallen in (that kind of) love with his dead older sister]]
* Kanan is Hakkai's older sister in the ''Manga/{{Saiyuki}}'' manga, although this was edited out of the anime version, and, as they had been SeparatedAtBirth or very close to it, they weren't originally aware of it. A tie-in novel also suggested that they might be [[{{Twincest}} twins]] as well, which was approved by WordOfGod.

* In ''VisualNovel/{{Clannad}}'', Tomoya's wild imagination causes him to imagine the Sunohara siblings as this when he [[https://www.youtube.com/watch?v=fEn7Magci80 misinterprets one of Mei's lines]].

* [[spoiler:Hoshina Utau]] from ''Manga/ShugoChara'' ''loves'' the resident {{bishonen}} catboy of the series, Tsukiyomi Ikuto. The thing is, [[spoiler:her real family name is Tsukiyomi and she ''is'' Ikuto's sister]], which does explain why Ikuto is so cold towards her advances -- in fact, [[spoiler:he's downright disgusted when she kisses him]]
* Yui from ''LightNovel/MuvLuvAlternativeTotalEclipse'' is in love with Yuuya even after eventually learning he's really her half-brother.
* The secret of the [[BigScrewedUpFamily Kuhouin family]] in ''LightNovel/{{Kurenai}}'' is that [[spoiler:each girl born into the family is imprisoned in the "Inner Sanctuary" for their entire lives, for the sole purpose of bearing the children of their brothers to continue the lineage. Their very existence is kept hidden from the public, and the male members of the family marry women from outside the family just to keep up the masquerade]].
* In ''Anime/GhostHound'', the main character, Tarou, has a slight obsession with his sister which leads to him accusing the girl he likes of being his sister reincarnated as an explanation for why he thinks about her all the time.
* In ''Manga/DGrayMan'', Komui's attitude toward his sister Lenalee straddles the line between {{Big Brother Instinct}} and this trope; even the other characters find it a little creepy and frequently remark on his obsession.
* ''Anime/CandyBoy'''s main theme is the yuri subtext between (fraternal) twin sisters, Yukino and Kanade. The lyrics in the recap video appended to the first episode proclaim that "this may be the best pairing in the history of the world".

* ''Manga/{{Berserk}}'' subverts this somewhat, since [[spoiler: Serpico and Farnese were in love at one point and are half-siblings, but Serpico's love becomes more brotherly after he learns that Farnese is his half sister.]]
* Minato and Juunichi's relationship in ''VisualNovel/AkaneIroNiSomaruSaka'' [[LampshadeHanging is seen as this by everyone]] despite the siblings' insistence that it's not. It turns out everyone else was spot on, because when the show ends, Minato is the one who ends up winning. Interestingly enough, the level of incest between Minato and Juunichi changes depending on the version of the story. They're fully blood-related in the original PC game, but Minato is adopted in the [=PS2=] version and possibly in the anime as well.
* In ''Mahou Shounen Majorian'', Mari falls in love with the magical girl form of her brother, Masaru--which makes it kind of hard to classify.
* ''Webcomic/AxisPowersHetalia'' has both the traditional brother/sister version ''and'' a HoYay one. On a hand, the {{Yandere}} Belarus would love to marry her older brother Russia (also a {{Yandere}}), which freaks him out no end. On the other, the AnnoyingYoungerSibling South Korea isn't much more successful in getting his older brother China (and sometimes his ''other'' older brother, Japan), to acknowledge his more-than-brotherly affection. Both cases are played for laughs.
** Switzerland and Liechtenstein, while NotBloodSiblings are shown in-canon to be ''very'' close, leading to some ShipTease. It probably doesn't help that they also act like a young married couple at times rather than as brother and sister.
* At one point in the ''Manga/AhMyGoddess'' manga, a botched love potion fed to Keiichi causes any female to meet his eyes to become passionately infatuated with him -- starting with his sister Megumi. She says, "Our love can transcend these foolish bonds of blood!" His horrified reaction: "'''Oh no it can't!'''" Fortunately, neutralizing the potion [[LaserGuidedAmnesia wipes her memory of the incident]].
** As you can [[RuleThirtyFour easily guess]], there are {{hentai}} dōjinshi expanding on this incident.
** The anime-remade episode has this too, and is more outrageous, where Megumi goes to the length of clinging onto Keichii and fighting over him with Skuld, Urd and Peorth who also fell victim to the effect of the potion.
* in ''Manga/KareKano'', Kazuma and Tsubasa simutanously get crushes on their other as their parents get married. Cue {{Squick}} from parents, {{Wangst}} from Kazuma which make him run away from home, which makes poor Tsubasa down the mental road before it gets better.
* ''[[PlayingWithATrope Somethinged]]'' in ''Anime/FreshPrettyCure''. Miki's brother Kazuki lives with her father (her parents are separated, presumably divorced) and uses his name. She hasn't told her best friends they they're related, and in the first episode she refers to their upcoming outing as a date. The second episode focuses on one of their dates; it also features TheReveal that they're related, but you'd be forgiven for missing this detail. Eventually it's revealed that, when her friends assumed Kazuki was Miki's boyfriend, Miki went out of her way not to correct them because she thought it was cute.
** Considering the [[LesYay yuri subtext]] in the ''Franchise/PrettyCure'' franchise in general, we have the only Precure-sisters Love and Setsuna from the same series. They are step-sisters, though.
* ''Manga/VampireGame'': It's a big, feuding RoyallyScrewedUp family, and brother-sister incest is the ''least'' of their problems -- that couple looks downright ''normal'' in comparison, LoveMakesYouCrazy moments aside.
* ''Manga/HappyWorld'': The explanation Takeshi uses to explain Elle's connection to him is that she's his step-sister. Cut to Takeshi exclaiming loudly to her in a classroom "We should make a baby." And they actually go halfway through the act before realising that they're not emotionally ready for it.
** As it turns out, their relationship to eachother [[spoiler: ''is'' technically step-siblings... probably. Takeshi's mother is Elle's mother, but Elle doesn't have a father, so it's a bit complicated.]]
** Their child, Prayer, is eventually born... but not through normal means. Takeshi and Elle [[spoiler:fuse their bodies, and Prayer is born when they split apart again.]]
* ''Manga/NinjaNonsense'' has Sasuke imagining that he's the object of an UnwantedHarem. He disturbingly imagines that Shinobu is his sister.
* ''Oniichan Control'' has the brother who fled from his younger sister because he's developed inappropriate feelings for her. Unfortunately, his younger sister is not only fully aware of these feelings, but returns them in a big way. ''And'' she's a first-rate [[ManipulativeBastard manipulator]] beneath her cutesy facade, managing to track him down, get admission to the same college he goes to, and worm her way into becoming his roommate. This goes so far that she's willing to [[MurderTheHypotenuse stab a girl she thought was interested]] [[BrotherSisterIncest in her brother]]. The entire series is about the brother trying to ''avoid'' this trope while the sister tries to ''invoke'' it.
* Two examples of this, running in both directions, are present in ''Manga/HatsukoiLimited''. Ayumi's brother, Yuuji, is a definite siscon, and Koyoi Bessho is defined by her brother complex. Of course, they are but one small part of the LoveDodecahedron that permeates the series.
* In the spinoff of ''Manga/{{Genshiken}}'', ''Anime/KujibikiUnbalance'' has the main character's sister pursuing him endlessly, even going so far as to [[spoiler: try perfume that is actually a love potion to seduce him. Instead she just succeeds in getting MC's best friend to kiss MC much to his sister's despair and anger]].
* An example also occurs in Yuu Watase's pre-''Manga/FushigiYuugi'' manga, ''Manga/ShinshunkiMimanOkotowari''. Asuka Higuchi falls for her half-brother Manato Sudou early on in the story, and he eventually comes to reciprocate. [[spoiler:And then they learn that they aren't blood-related after all--in a very mind-twisting way.]]
* In ''Anime/ShinkonGattaiGodannar'', English pilot Knight Valentine will flirt with any female in sight, much to the consternation of Ellis, his sister and partner, who thinks he doesn't notice her. But if [[spoiler:the way he looks at her swimsuit-clad form and the fact that he sees Ellis' face when an amnesiac Mila is hitting him with CharmPerson are any indication, he ''does'' notice her in that way.]]
* This issue is addressed in episode 9 of the second season of ''Anime/HellGirl''. The incestual love in this case is one-sided, and the offending sibling is, of course, sent to hell. The episode ends on a lighter note; the aforementioned sibling is not tortured on the ferry (unlike sinners who have done worse), and there is the knowledge that the brother and sister will eventually be reunited as per the terms of the curse.
* In ''Anime/QueensBlade'', Elina [[BigSisterAttraction lusts after]] [[LustObject both her older sisters]]:
** She wants to with sleep with Leina and pouted when she wasn't allowed to [[GirlsLove spend the night in her room]], in the first episode. Leina is more than aware of Elina's blatant incestuous crush on her, which is part of the reason she ran away from home and doesn't intend to return. Though she still [[SkinshipGrope indulges Elina on occasion.]] Such as episode 9, where she bathed together with her, then spent the night spooning with her in bed, while both were in the nude.
** It's also implied in the main series that Claudette is in love with Elina, but her feelings are unrequited due to Elina being in love with Leina.
** The ''"Hide & Seek"'' manga continuity took the subtext and [[TriangRelations ran with it.]] While Elina's feelings for Leina remain paramount, the manga features a romantic subplot between her and Claudeete and even has Leina say [[ShipperOnDeck she supports her sisters being together]] (chapter 28).
* ''Kiss x Sis'' is about the ongoing incestuous affair between Keita and his older twin stepsisters, [[TomboyAndGirlyGirl Ako and Riko]], who take turns waking up him up each morning by making out with him beneath the covers. Their trysts [[HotterAndSexier become increasingly risque]] as the series (and their relationship) progresses, to where Keita has even brought [[{{tomboy}} Riko]] to orgasm by [[spoiler: performing oral sex on her]]. Despite all this, they have yet to actually engage in intercourse, which remains in question as the manga is still ongoing.
* The original OAV series of ''Anime/TenchiMuyo'' is '''filled''' with incestual attractions -- the whole mess basically got started when Ayeka fell in love with and was engaged to marry her elder half-brother Katsuhito/Yosho. See IncestIsRelative for full details.
* ''Boys Empire'' is a [[LoliconAndShotacon shotacon]] doujinshi series that begins with Makoto regularly having sex with his older sister, Mina. When their mother, Umeko, finally realizes what they've been up to, she gets in on it, herself. They even work out a weekly schedule that determines which of them gets to sleep with Makoto on which days. By the end of the series, both of them (and his girlfriend, Hitomi) [[BabiesEverAfter end up pregnant with his children.]] Umeko, in particular, gives birth to twins, with one being his father's child and the other being Makoto's, since they impregnated her on the same night.
* [[spoiler: Seimei is a LoveMakesYouCrazy version]] in ''Manga/{{Loveless}}'' towards Ritsuka. [[spoiler: To Seimei, him and Ritsuka are the only two people in the world. The fact that the two are full-blooded brothers is probably the least [[{{Squick}} squicky]] thing about him, though.]]
* Silvia in ''Anime/GenesisOfAquarion'' has a pretty obvious attraction to her older brother Sirius, becoming incredibly jealous of even the slightest hint of romantic interest in other women. It seems her insistent belief that he is the reincarnated lover of the woman she is the reincarnation of has a lot to do with this. [[spoiler: In reality, reincarnation is largely to blame, but not in the way it first seems: they are actually both reincarnated from the same person, each holding a fragment of Celiane's soul. The longing of the two halves to be united again causes Silvia's apparent crush on her brother; he doesn't feel the same way because he got stuck with the negative aspects of Celiane's soul and memories, and so sealed them away at a young age.]]
* In ''Manga/{{Georgie}}'', the PluckyGirl Georgie is romantically pursued by her two adoptive brothers, [[RedOniBlueOni Abel and Arthur]]. Since the three were raised together and Georgie herself didn't know she was adopted for many years... well, yeah. In the anime, she doesn't end up with either of them but they leave together as a family. In the manga, however, it ends ''very'' differently. Georgie does fall for oldest sibling Abel. They even have the [[SexyDiscretionShot shoujo equivalent to a sex scene]]. By the end of the manga, Abel has been killed and Georgie has his child, and decides to return to Australia, [[PairTheSpares where Arthur is waiting for her]], having returned several years earlier.
* This is a catalyst for one of the storylines in ''Anime/{{Mononoke}}''.
* In ''Manga/UruseiYatsura'', the Mizunokoji siblings have a one-sided version of this going on... [[SubvertedTrope more or less]]. According to their screwed up traditions, youngest daughter Asuka was raised in total isolation from the opposite sex, and with the terrible job her maids did in regards explaining the other sex (something worsened by her fact her first encounter with a guy was [[LovableSexManiac Ataru Moroboshi]]), [[DoesNotLikeMen she's terrified of men]]... except for "Big Brothers", whom her maids made out as a special, dependable, trustworthy exception to men in general. Between her phobia and her naive ignorance, she not only has a crush on her older brother Tobimaro, but is constantly trying to perform deeds with him that are only appropriate between lovers. Tobimaro, meanwhile, is perfectly aware of their relationship and that the things she tries are ''not'' appropriate, thus he freaks out when the poor girl comes on him. The fact that their crazy mother blames Asuka's actions on him, despite the fact she was the one who arranged for Asuka to be raised the way she was, only makes things more galling for him. The fact Asuka also has SuperStrength and is thus prone to crushing his bones whenever she gets frightened or romantic does ''not'' help.
* 15-year-old Sakurako Saiki from ''Manga/SakuraGari'' is a scary {{Yandere}} who is incredibly possessive of her older brother, the main character Souma, [[spoiler: and has had sex with him more than once.]]. For further subversion, [[spoiler: Sakurako is actually a ''male'', Youya, who calls himself like that after the horribly fucked-up death of his mother... whose name was Sakurako.]]. And even ''more'' subverted: [[spoiler: They're NotBloodSiblings. Souma is the son of the Saiki leader and his dead lost love, Abigail; Youya/Sakurako is the child of the original Sakurako ''and'' the retainer Katou. When Youya/Sakurako commits suicide, Katou reveals this and stabs Souma - apparently, to death.]]
* Iina from ''Manga/KokoroLibrary'' appears to have quite a thing for her sister Kokoro. She tries to steal kisses from her and gets quite upset when Kokoro decides to spend time in the bath with her ''other'' sister, Aruto, instead of her. Kokoro clearly loves Iina a lot too, but in a ''sisterly'' fashion.
* In ''Manga/{{Freezing}}'', Satellizer was abused by her half brother. He molested her as well, though their blood relation was in fact the only thing that kept him from outright raping her, what he did was enough to emotionally scar Satellizer to the point that she could no longer stand being touched by ''anybody''.
** And, for some irony, the one guy who's the exception, the one guy who can touch her because he treats her with dignity and compassion? He was attracted to her initially due to her resemblance to his big sister, and [[spoiler: and given they share genetic implants tied to said sister that give Satellizer a genetic resemblance, they are an indirect example of this trope as well, except Kazuya Aoi (the guy) is a far, far better choice for Satellizer by far.]]
* This is a plot point in ''Manga/EternalAlice''. The main characters are a boy named Aruto, his love interest Arisu, and his little sister with a very obvious crush on him, Kiraha. It is revealed later that [[spoiler:Arisu isn't real, and Aruto made her up because he couldn't deal with his incestual feelings for Kiraha.]]
* Shinogu and Hatsumi from ''Manga/HotGimmick'' are NotBloodSiblings. Shinogu is in love with Hatsumi but, in an effort to not burden her with his feelings, he tries to put distance between them. Hatsumi actually offers herself sexually to Shinogu at one point but he turns her down. And in the Hot Gimmick S novel, she actually leaves her [[DomesticAbuse abusive boyfriend]] Ryoki for Shinogu.
* ''LightNovel/{{Durarara}}'': Namie is quite blatant to admit that her love for her younger brother Seiji is not familial. Even Izaya finds it a bit disgraceful.
* The novel adaptation of ''LightNovel/{{Baccano}}'' says that [[HeroWorshipper Graham Specter]]'s first love was his sister. No information has been given beyond that so far.
* In ''Anime/{{Gankutsuou}}'' Andrea actually tries to marry and rape his half-sister Eugenie. Though only to deliberately humiliate her and her family.
* Ryo from ''VisualNovel/FinalApproach'' is quite obsessive over his little sister Akane and she's generally reciprocative. It's generally played for laughs as nothing more than an amusingly intense sister/brother complex, but it is worth noting that Akane insisted on taking part in the contest with [[UnwantedHarem the other girls]] to see who got to play the role of Ryo's bride.
** When Akane is sick Ryo rushes home to take care of her. It's at this point the other girls realize they're not competing with each other but with Akane.
* In the anime of ''Manga/SamuraiDeeperKyo'' , ''BigBad'' Nobunaga Oda and his right-hand henchwench Shatora are an incestuous brother-sister pair who desire who turn the "boring world" of Sengoku-Era Japan into a literal "hell of battles" so they can openly be together in the chaotic new world. They reveal that their ''StartOfDarkness'' was because society tried to force them apart by making their relationship taboo in the first place.
* In ''Manga/TheKindaichiCaseFiles'', a man masquerading as a serial killer is on a RoaringRampageOfRevenge for his dead lover...it's revealed after he is DrivenToSuicide that said lover was his sister. (And the lake where the murders take place is rumored to have been the suicide spot of another pair of sibling lovers.)
* ''Swing Out Sisters'': Yuuta's two older sisters have the hots for him, and he starts intense sexual affairs with both. The sisters agree to share their brother, and find that they enjoy each other's bodies as well, thus forming a stable sibling love triangle.
* ''Bloods: Inraku no Ketsuzoku 2'': The Sagemiya family is cursed in that its members are sexually aroused in the presence of another of the same bloodline. Misaki twin brother Shun are both disgusted over this and have sworn to resist the curse. However, Shun loses his composure and starts banging their big sister Kagu. After Misaki finds out, she too gives in to the curse and begins an affair with Shun.
* ''Love 2 Quad'': The hero gains power via ecchi activities, one of which is deflowering his younger sister.
* ''Hime-Sama Love Life'': An unpopular brother and his shy sister decide to have their first times with each other.
* ''Baku Ane: Otouto Shibocchau zo!'': A guy's four sisters become his harem.
* Pretty much the fundamental appeal of ''VisualNovel/YosugaNoSora'' combining with {{Twincest}}. Both tropes are also [[{{Deconstruction}} deconstructed]]: Sora’s attraction to Haruko is due to her physical and emotional dependence on him, coupled with her psychological instability, and while Haruko’s feelings are mutual, he struggles with the morality of their relationship, knowing society won’t accept them. Their arc ends with the two moving overseas, hoping to finally live happily together.
* In ''LightNovel/{{Corsair}}'', Jean-Hughes saves his seven year old brother Canale from being raped, but he can't stop imagining himself doing the exact same thing to him. This leads to him pinning the guilt and blame on Canale and loathing him even more.
* Cain Hargreaves, the lead of the ''Manga/CountCain'' manga and its sequel series ''Godchild'', has this as part of his origin story. Turns out part of why he has the family curse so bad/ slash why his parents always acted so weird with him/[[ArtisticLicenseBiology why he has]] sort of golden eyes, is that his mother isn't his mother. His father's crazy sister Augusta is. When he finds out and goes to see her in her asylum, she jumps to her death in front of him.
** For some reason, Kaori Yuki [[FanonDisContinuity decided to reveal]] in the end that MagnificentBastard Alexis was actually manipulated by his much more evil sister Augusta because... she was just that evil, apparently. Yeah, evil enough to seduce her brother into impregnating her and then spend the next twelve years catatonic in an asylum before killing herself just to traumatize the kid. According to her ghost, at least.
* ''[[SchoolgirlLesbians Shoujo Sect: Innocent Lovers]]'': In the first episode, Chizuru goes to Naitou for advice on how to confess her feelings for the girl she was secretly in love with. Since Naitou didn't feel like being bothered, she tells her to just say so and get it over with. Adding that she didn't want to hear anymore about it until Chizuru had finally done it, and demanded she provide proof. So [[BigSisterAttraction she confesses her love to Shigure that night.]] Just when it seemed that her feelings were unrequited, Shigure reveals she'd secretly been in love with her too and makes love to her. The next day at school, Chizuru delivers on her promise by showing Naitou a photo of them in bed together, which she had taken with her cellphone camera. When Naitou sees the other girl had been Chizuru's older sister, [[MyGodWhatHaveIDone she regretted having said anything]] since, had she known, she would've advised against it.

* In ''[[Literature/ArabianNights One Thousand and One Nights]]'', Dunya is infatuated with her older brother Sehara. She actually demands that he kiss at one point (which he does).
* Somewhat referenced to in ''VisualNovel/HigurashiWhenTheyCry''. Mion Sonozaki mentioned in the sound novels that she'd marry her twin sister Shion if she was a boy, ''not'' mentioning if they weren't related. [[IncestSubtext The official art including the sisters]] [[FanService does NOT help.]]
* ''Anime/MawaruPenguindrum'''s first episode has Kanba Takakura kissing his younger sister Himari after she's resurrected and while she's sleeping. It hasn't been referred to later, though. [[TemptingFate Let's give it time.]]
** It's given a rather philosophical twist in this series; Kanba's InternalMonologue in the scene revolves around [[ScrewDestiny defying fate]] and the animalistic [[ArcWords survival strategy]] to determine one's free will. Basically, doing something that your very biology abhors is used as a sign for freedom of choice.
** In the Penguindrum novel, the scene where a posssessed Himari pulls something out of Kanba's chest ([[spoiler: his life energy]]) is a little more suggestive than in the anime version. Not to mention, in the anime the kiss scene went into fade to black when Kanba's lips were milimeters away from Himari's. In the novel? It's described quite in detail.
** Taken further in episode 12, where [[spoiler: before dying again (temporarily), the possessed Himari shares a last goodbye with Kanba. When they're the only ones in her Dream World. [[http://imageftw.com/uploads/20110929/1317318196481.jpg While she's pretty much naked except for her boots and the Penguin Hat, and Kanba's chest is exposed due to self-inflicted Clothing Damage]]. [[DoesThisRemindYouOfAnything A sexual encounter wouldn't have been out of place]].]] Though there ''may'' be a twist here, [[spoiler: with the sex-charged interaction itself being more in between Kanba and the ''possessor'', the Princess of the Crystal, rather than between him and Himari. [[MindScrew It's... hard to tell]].]] It happens again in episode 17, when [[spoiler: Himari/the Princess [[http://i42.tinypic.com/2wp8c51.jpg strips again]], [[CooldownHug cradles]] [[http://i39.tinypic.com/2em0gih.jpg a depressed Kanba to her/Himari's bare bosom]], and pretty much [[http://i40.tinypic.com/243mely.jpg throws herself into his arms]]. Again, not clear who is who here, but still. . .]]
** Aaaand then... [[spoiler: it's ''subverted''! Himari and Kanba are NotBloodSiblings. Episode 19 explains that Himari was adopted into the Takakura family after she was rescued from a plance named the Child Broiler... and her savior was her and Kanba's brother, Shouma. Kanba himself is adopted too; he and Shouma relied on each other to survive, but he only felt truly as a Takakura when Himari welcomed him into the family.]]
** Then finally reintroduced in the form of {{Twincest}} when [[spoiler: Masako, Kanba's stalker and apparently jealous ex, turns out to be his biological twin sister, and Masako and Kanba were both well-aware of their relationship the entire time. Having physically assaulted and mind-wiped the rest of Kanba's ex girlfriends since she didn't see them as good enough for him, Masako ultimately turns her sights on Himari, whom she sees as both familial and romantic competition, but later sets it aside when Kaba pulls a FaceHeelTurn.]]
* ''Manga/DearBrother'' has [[spoiler: Rei Asaka's obsession with her older half-sister Fukiko Ichinomiya, and Fukiko's abusive behavior towards her]] as one of the driving forces of the plot.
* Averted in ''LightNovel/BakaAndTestSummonTheBeasts'' because while Akira Yoshii really wants to move her relationship with her younger brother to the next level, the normally super-horny Akihisa surprisingly expressly considers incest to be disturbingly immoral and constantly resists the nonstop attempts at seduction of his older sister.
* ''Manga/ToLoveRu'' seems to heading this way, if Momo gets her way. Played for laughs when Mikan trying to resist the effects of [[LovePotion Celine's ]][[LoveIsInTheAir pollen.]]
* In Yuki Suegutsu's infamous ''Manga/EdenNoHana'' manga, the protegonist, Midori, was put in foster care and then was raped by her adoptive brother.
* ''LightNovel/{{MM}}'' main character Taro is actively pursued by his older sister AND [[ParentalIncest mother]]. When he gets amnesia for an episode both try to pretend being his pregnant lover.
* Happens quite frequently (both within the story's present time and in flashbacks) between [[spoiler: Michel]] and [[spoiler: Coco]] in the manga ''Manga/CopernicusBreathing''.
* ''Manga/OukeNoMonshou'' has the {{Ancient Egypt}}ian princess Isis who is in love with her brother, Pharaoh Memphis. Her jealousy towards any woman remotely interested in him [[spoiler:extends beyond the grave]], and it actually kicks off the plot [[spoiler: since Carol, {{The Hero}}ine, fell victim to one of Isis's curses and then was thrown into the Egypt of the past...]]
* For the first volume of ''Manga/{{Ichiroh}}'', Nanako's brother had it bad for her and even followed her while she was off studying for exams. Nanako, of course, did not return these feelings. Eventually, he realized his sister was maturing while he was not and set off to improve himself to be worthy of her. We never see him again except in passing and omake strips, presumably because incest jokes in a light-hearts 4-koma strip would be kinda out of place.
* In ''Manga/{{Ooku}}: The Inner Chambers'', it's revealed that Akimoto and his sister Kinu slept together, resulting in a daughter. When Kinu asked if he entered the Ooku because he was disgusted by what they did, his response was that if he hadn't, he'd be forced to marry, and he didn't want to father a child with anyone but her. Emonnosuke is ''quite'' amused when he finds this out about Akimoto, and points out that even Japan's origins center around this trope. It's probably pretty telling that he actually gets one of the ''happier'' endings: [[spoiler: after Shogun Tsunayoshi dies, he retires and returns home, meeting his daughter/niece for the first time, and is said to have lived the rest of his life out in peace with his family.]]
* Deconstructed to the point of FanDisservice in ''LightNovel/SasamisanAtGanbaranai'': In order to keep the power of Amaterasu in their bloodline, siblings in Sasami's family are forced to marry. Due in part to what is apparently a lobotomy, the sibling which does not possess Amaterasu's power is conditioned to care for and unconditionally love the one that does.
%%* It's the whole point of, and PlayedForLaughs in ''LightNovel/OniAi''.
* ''Manga/UchiNoMusumeNiTeODasuNa'': In chapter 9, Artemis challenges her older sister, Athena, to a duel to decide whether she and her daughter would have to [[spoiler: return to their home planet with her]]. The match is even, until Athena catches Artemis off-guard by suddenly tongue kissing her. Then she capitalizes on Artemis' shame and confusion by fingering her, and finishes her off by 69ing with her in midair. Artemis [[BeatThemAtTheirOwnGame tries to retaliate]], but she climaxes first. She concedes the match, but still [[WhatTheHellHero calls Athena out]] for using such [[DefeatByModesty underhanded tactics.]]

* In the Manga for [[Manga/ElfenLied Elfen Lied]], [[spoiler: this is the entire reason Lucy/Nyuu/Kaede's half-brother was born. Kakuzawa wants him to mate with Lucy/Nyuu/Kaede and procreate more Silphelits.]]
* One of the main drives of Manga/AkatsukiNoAria's story is how Aria Kanbara and Natsuo Nishimikado are half-siblings, what with Aria being an HeroicBastard, but are ''very'' attracted to each other. [[spoiler: it turns out that [[NotBloodSiblings NOPE]], they aren't related, and later Aria has to search for her actual birth father.]]
* Happens in ''Manga/NozomuNozomi'' when [[spoiler:Nozomu's sister [[GenderBender turns into a boy]]. She gets a RagingStiffie that won't go away. Nozomu tells her to [[ADateWithRosiePalms do the obvious]] but she's too scared so he "helps" her, just this one time]].
* Being focused on otaku it's no surprise this trope gets brought up and discussed in ''[[Manga/ShinozakisanKiWoOtaShikaNi Don't Become an Otaku, Shinozaki-san!]]'' Makoto's otaku buddies are jealous the he has a real life little sister, but Makoto himself feels no attraction to her (least of all because she tends to treat him badly), nor to any of his sister's friends specifically ''because'' he's known many of them since they were very young. Akina has no interest either, viewing Makoto as a gross otaku even as she becomes one herself, and because she falls more under SchoolGirlLesbian anyway.
* It's revealed at the end of the oneshot manga ''Up And Down'' by Nishi Uko that the unnamed woman the protagonist pines for was in love with her sister. Her sister died so she [[HappilyAdopted adopted]] her niece. The woman states that she isn't sure if it's a blessing or if it's some sort of divine punishment because [[StrongFamilyResemblance her niece looks a lot like her mother.]]
* ''LightNovel/TheIrregularAtMagicHighSchool'' has Miyuki Shiba, who is VERY attached to her older brother Tatsuya and has [[spoiler: deliberately]] geared a good part of her life around him. On the other hand, Tatsuya certainly cares for Miyuki but he's got his own and huge issues and can barely feel actual emotions as a result. [[spoiler: It turns out that Tatsuya's only ''truly'' remaining emotion is his brotherly love for Miyuki, but later, so as the body of his sister genetically "improved" is enough to nullify any effects of incest between siblings, their aunt announces Tatsuya her son and adopts him, so that they could marry as cousins. So later in the story, [[ArrangedMarriage they're engaged to marry]].]]
* In ''Manga/TokyoGhoul :re'', [[spoiler:[[BigBad Nimura Furuta]]]] states that he has been in love with Rize since they were children, and intends to [[AndNowYouMustMarryMe marry her]] once his plans come to fruition. In fact, his decision to nearly kill her and allow [[spoiler:[[MadScientist Dr. Kanou]]]] to imprison and experiment on her was because he couldn't stand the thought of her having children with anyone else. It becomes even creepier when one examines the family tree in the background, because [[spoiler:[[GreaterScopeVillain Tsuneyoshi Washuu]]]] fathered ''all'' of the children in that generation. That makes Rize his '''half-sister''', in a family that routinely practices RoyalInbreeding.
* The soft core {{Hentai}} manga, ''Aki Sora,'' has older sister Aki and her younger brother Sora engage in an affair after discovering a mutual physical and emotional attraction for each other. He also has an affair with his PsychoLesbian [[{{Twincest}} twin sister, Nami,]] after she rapes him as payback for banging her crush. Later on its revealed that their father left years ago because of [[DaddyHadAGoodReasonForAbandoningYou the scandal of having sired the three siblings with one of his younger twin sisters.]] While he does take Aki away for the two's own good, the manga ends with her and Sora reuniting, [[MaybeEverAfter implying they have a chance for a happily ever after]].
* ''Anime/PantyAndStockingWithGarterbelt''[='=]s Scanty and Kneesocks engage in plenty of sex when their father is not looking.
* Asuka from ''Manga/UruseiYatsura'' loves her brother to the point where she wants to marry him, he on the other hand is very uncomfortable with this, this is mainly due to her growing up isolated from men and developing a phobia of them after hearing exaggerated statements and her first encounter with a male being the perverted Ataru, her brother is one of the only males she is not afraid of, the other being Mendou because he reminds her of him.

* While it's not ''quite'' this, ''Manga/FrankenFran'' has a man named Kusinoki have sex with some sort of octopus hybrid that greatly resembles his deceased sister Azusa, and the dialogue suggests he had wanted to do this to the real Azusa too. [[spoiler:[[KarmicDeath His body is used as nourishment for the octopus hybrid's numerous offspring.]]]]
* ''Manga/SisconAniToBroconImoutoGaShoujikiNiNattara'' has Ritsu and Uta Fukami. Originally they are merely close siblings, but after Uta is annoyed that Ritsu plays with her less due to his friends keeping him at school more often, including one girl that shows interest in him, [[TheBeard Ritsu chooses to lie to his friends that Uta is his girlfriend in order to be able to find excuse to spend more time at home with his sister]] (helped by the fact that they don't attend the same school, and thus none of their friends know their actual relationship. Ritsu's friends only know that he has a sister, and Uta's friends likewise), all the while pretending they're lovers outside of their home. However, their pretend lover relationship [[RomanticFakeRealTurn eventually turns into a geniune romance]], though they choose to try their best to not show it at home in fear of their parents finding out.
* ''Tayu-Tayu'': In chapter 6, Reiju happens to overhear someone having sex inside an abandoned watermill and decides to see who it is. He's surprised to find it's two of his classmates: Haruka and ''[[{{Twincest}} her younger twin sister]]'', Sayaka. After the girls hogtie him, Haruka explains that she and her sister had been having sex with each other ever since all the boys their age had moved away. [[SituationalSexuality So the twins had no other options for relieving their pent-up hormones]]. Haruka adds that she and Sayaka soon became [[SingleTargetSexuality addicted to each other's bodies]], until it finally became impossible for them to be in the same room without [[CoitusEnsues tearing each others clothes off.]]
* Averted in the final arc of ''Manga/FoodWars''. Asahi Saiba shows up out of nowhere and [[AndNowYouMustMarryMe tries to force Erina Nakiri to marry him]], much to her displeasure (and Soma's, for that matter). After Soma defeats Asahi in the BLUE, it's revealed that he's the son of Azami (Erina's father) from a one-night stand he had with a random woman when he was a student.

* ''Manga/NininGaShinobuden'' has Sasuke imagining that he's the object of an UnwantedHarem. He disturbingly imagines that Shinobu is his sister.

* It is heavily implied in ''Manga/{{Narutaru}}'' that the bully Aki Honda and her older brother Yasuhito have a ... rather intense relationship.
** It's downright spelled out in the manga. [[spoiler: So much that Aki is once shown straddling Yasuhito while practically naked. Then, Oni shows up, kills Yasuhito by smashing his head on the wall, and rapes and kills Aki as revenge for what they did to his master, Hiroko.]] Said scene is censored in many countries in the world (even the Japanese version got censored retroactively) and spelled the end of the series' publication in many others.

%%* It's the whole point of, and PlayedForLaughs in ''LightNovel/OniiChanDakedoAiSaeArebaKankeinaiYoNe''.

* This is a plot point in ''Manga/KagihimeMonogatari Eikyuu Alice Rondo''. The main characters are a boy named Aruto, his love interest Arisu, and his little sister with a very obvious crush on him, Kiraha. It is revealed later that [[spoiler:Arisu isn't real, and Aruto made her up because he couldn't deal with his incestual feelings for Kiraha.]]

* Due to technicalities regarding reincarnation in ''Manga/CardCaptorSakura'', Syaoran is, technically speaking, Sakura's half-brother (although they don't know that until ''very'' late in the series). [[spoiler: Sakura's father is a reincarnation of Clow Reed, albeit one without any known magical abilities, and Syaoran is one of Clow Reed's descendants, on his mother's side.]] This being a series by Creator/CLAMP, it doesn't ''really'' matter, or even factor much (if at all) into the plot.

* In ''Anime/RevolutionaryGirlUtena'', not only does Touga's sister Nanami harbor an intense crush on her older brother, but she also has a [[ClingyJealousGirl near-insane jealousy]] of anyone or anything that might attract more of his attention and love than she does. There is also the strange love-hate relationship between Kozue Kaoru and her twin brother Miki, best displayed in the bizarre bathtub-and-straight-razor scene from the ''Utena'' movie. Most important to the plot, though, is [[spoiler: the semi-consensual relationship between Anthy and her manipulative and domineering brother Akio]].
** In the first example, a few of the last episodes of the series {{Deconstruction}}s Nanami's infatuation with her brother by introducing the possibility that they are not siblings [[spoiler:and then reveals that they are siblings; Touga is just being manipulative]] and explores [[ShooOutTheClowns Nanami's emotional confusion resulting from that distancing]].

** In the first example, a few of the last episodes of the series {{deconstruct}}s Nanami's infatuation with her brother by introducing the possibility that they are not siblings [[spoiler:and then reveals that they are siblings; Touga is just being manipulative]] and explores [[ShooOutTheClowns Nanami's emotional confusion resulting from that distancing]].

* ''Bloods: Inraku no Ketsuzoku 2'': The Sagemiya family is cursed in that its members are sexually aroused in the presence of another of the same bloodline. Misaki twin brother Shun are both disgusted over this and have sworn to resist the curse. However, Shun loses his composure and starts banging their big sister Kagu. After Misaki finds out, she too gives in to the curse and begins an affair Shun.

* ''Swing Out Sisters'': Yuuta's two older sisters have the hots for him, and starts intense sexual affairs with both. The sisters agree to share their brother, and find that they enjoy each other's bodies as well, thus forming a stable sibling love triangle.

*** And Haruko doesn't quite reciprocate, but at least clearly knows and doesn't mind. After describing his use of TheHandsOnMethod, we get this:

* In an unusually negative scene, there is a pseudo-incestuous rape sequence in ''Manga/AyashiNoCeres''. It also contains a subversion and plot device of this trope, seeing as [[spoiler:Shisou Mikage, who is still madly in love with his wife Ceres, is reincarnated as Aki Mikage. Aki's twin sister Aya is the reincarnation of Ceres, and she is eventually led to kill him to save both herself and Ceres. Aki and Aya themselves ''do'' love each other greatly, but ''not'' in an incestuous way]].

* ''Manga/OniisamaE'' has [[spoiler: Rei Asaka's obsession with her older half-sister Fukiko Ichinomiya, and Fukiko's abusive behavior towards her]] as one of the driving forces of the plot.

* Averted in the final arc of ''Manga/ShokugekiNoSoma''. Asahi Saiba shows up out of nowhere and [[AndNowYouMustMarryMe tries to force Erina Nakiri to marry him]], much to her displeasure (and Soma's, for that matter). After Soma defeats Asahi in the BLUE, it's revealed that he's the son of Azami (Erina's father) from a one-night stand he had with a random woman when he was a student.

* Pretty much the fundamental appeal of ''VisualNovel/YosugaNoSora'' combining with {{Twincest}}. Both tropes are also [[{{Deconstruction}} deconstructed]]: Sora’s attraction to Haruko is due to her physical and emotional dependence on him, coupled with her psychological instability, and while Haruko’s feelings are mutual, he struggles with the morality of their relationship, knowing society won’t accept them. The arc ends with the two moving overseas, hoping to finally live happily together.

* Pretty much the fundamental appeal of ''VisualNovel/YosugaNoSora'' combining with {{Twincest}}.

* The soft core {{Hentai}} manga, ''Aki Sora,'' has older sister Aki and her younger brother Sora engage in an affair after discovering a mutual physical and meotionattraction for each other. He also has an affair with his PsychoLesbian [[{{Twincest}} twin sister, Nami,]] after she rapes him as payback for banging her crush. Later on its revealed that their father left years ago because of [[DaddyHadAGoodReasonForAbandoningYou the scandal of having sired the three siblings with one of his younger twin sisters.]] While he does take Aki away for the two's own good, the manga ends with her and Sora reuniting, [[MaybeEverAfter implying they have a chance for a happily ever after]].

* The soft core {{Hentai}} manga, ''Aki Sora,'' has older sister Aki and her younger brother Sora engage in an affair after curiosity got the better of them. Eventually he also has an affair with his [[{{Twincest}} twin sister, Nami,]] after she caught him with her girlfriend. Later on its revealed that their father left years ago because of [[DaddyHadAGoodReasonForAbandoningYou the scandal of having sired the three siblings with one of his younger twin sisters.]]
