[[caption-width-right:300:The ''[[LoveDodecahedron immensely]]'' complicated love story between two [[NotBloodSiblings step siblings.]]]]

[[GenkiGirl Miki Koishikawa]]'s parents pull her aside one day after school to announce to her that they're getting a divorce. It seems that they met another couple on their recent trip to Hawaii, and hit it off so well that both couples want to divorce each other, swap partners, and remarry. Even more incredibly, the four [[{{Polyamory}} want to all live together]] in one household... and the other couple have a boy Miki's age, the handsome [[DeadpanSnarker Yuu]].

Miki is dead set against the plan, but Yuu says that he's okay with it which makes her even more upset. The following day, Yuu enrolls at Miki's school. Miki has an accident in PE class and faints, and as she lays in the infirmary pretending to be unconscious, Yuu comes to check on her... [[DudeShesLikeInAComa and abruptly kisses her]]. Romantic Comedy-Drama ensues from then on, as [[{{Tsundere}} Miki]] is confused over her feelings and Yuu doesn't exactly help with his behavior, while other suitors of them try to break off their bonds, and for worse they have to deal with both their budding "love" as well as handling their parents's behaviors.

''Marmalade Boy'' (ママレード·ボーイ ''Mamarēdo Bōi'') is a shōjo manga by Wataru Yoshizumi. It was published by Shueisha in the magazine Ribon from May 1992 to October 1995 and collected in eight tankōbon volumes. The series was adapted by Toei Animation as a 76-episode anime television series which aired on TV Asahi in 1994 to 1995. This was followed by a prequel theatrical anime movie in 1995. The series was also adapted as a 30-episode live-action television series that was broadcast in Taiwan in 2002.

Now has a SequelSeries titled ''Marmalade Boy Little'' that follows Miki's and Yuu's half sister and brother.

Individual tropes should go to their [[Characters/MarmaladeBoy Character Sheet]].
!!Provides examples of:

%%* AgainstTheSettingSun
* AmicableExes: Miki's and Yuu's parents after their divorces and remarriages. Arimi and Yuu walk a really thin line here-- while Yuu didn't keep in touch with Arimi after he switched to Miki's school, he's pretty chill about seeing her again and doesn't really argue about maybe hanging out again. However, Arimi wants to get back together with him, which causes some strain.
* AscendedExtra: Kijima, Yuu's boss at the Junk Jungle. Started out as a one-panel character stuck in there just to let Miki know that Yuu quit his job so she wouldn't be home alone during their parents' honeymoons, became an [[{{Mentors}} all-wise mentorly type]] who had a history with Ryouko and Nachan.
* BadassAdorable: Meiko, in a (generally) non-violent fashion. Her gaze of steel has even made Yuu quail. Best exemplified when she tells Ginta to ''back off'' when it looks like Miki is developing a crush on Yuu, telling him it's his fault she hasn't let herself fall in love since she wrote him a love letter and he loudly denied any feelings he had for her in front of everyone.
* BeautyBrainsAndBrawn: The fashionable and popular Arimi is the Beauty, the booksmart and calm Meiko is the Brains, and the sporty and emotional Miki is the Brawns
%%* BicepPolishingGesture
* BigBrotherMentor: Kijima, as mentioned. His wife Rei becomes Miki's Big Sister Mentor as well.
** Arguably, to Yuu Satoshi is both this and his best friend. At the [[spoiler: end of the story arc that reveals Yuu's father to ''not'' be Satoshi's dad]], he lampshades this by quipping [[spoiler: "It would have been interesting to have you for a little brother," to which Yuu replies, "But I wouldn't have wanted you for a big brother."]]
*** [[spoiler:By the time of the sequel manga, Satoshi and Yuu are business partners in an architectural firm, and Satoshi is still serving in this capacity for Yuu and Miki.]]
** In the anime, he's also this to Miki sometimes. Specially [[spoiler: when she's depressed after Yuu announces he's going abroads: Satoshi takes her as his date for his highschool prom, lets her confide her woes on him, and then gently tells her that she's not the only one in pain. Miki understands Yuu's side of the story, and then Satoshi reveals that he sneaked Yuu and makes them dance outside.]]
* BigFancyHouse: Yuu and Miki's new house. And Meiko's, which is ''so'' big that Miki is all starstruck when she goes spend the night there. Also, Miwa and Suzu's houses: justified as their dads are very well-known architects and quite well-off, so they likely built their own homes.
%%* {{Bishonen}}: Yuu, Kei, Satoshi, Ginta, etc.
%%* BrattyTeenageDaughter: To a degree, Miki and Suzu.
* BreakingTheFourthWall: They do that a number of times. Quite unusual for a shojo manga.
* BrotherSisterIncest: [[spoiler:Yuu finds out that he and Miki are half-siblings and breaks up with her, but they eventually decide to get married anyway, with the caveat that they will never have children. ''Then'' Yuu finds out he was wrong about who his father was '''''again''''' and they're NotBloodSiblings after all.]]
** ''Squared'' in the last episode when [[spoiler:each new set of happily-married parents announces they're pregnant, adding half-siblings to the completely un-blood-related Miki and Yuu; worthy of note that these future half-siblings are not at all blood related to each other]]. And you thought polygamists had it bad.
* BroodingBoyGentleGirl: Yuu is mostly a cool and collected guy, but sometimes he's prone to quite the bouts of depression. When this happens, Miki attempts to comfort and understand his reasons so she can help him out. Sometimes it works well, sometimes it does't.
%%* CallingYourAttacks: Subverted in TheMovie.
* TheCameo: The manga has a very brief mention and image of Hagiwara Mio from ''Handsome Girlfriend'', another manga series by Yoshizumi.
** And in the anime, they even got [[Creator/SakikoTamagawa her voice actress]] from the 1 episode OVA to reprise her role
%%* CanNotSpitItOut
%%* CanonForeigner: Ryouko, Anju, Yayoi, all of the American characters...
* ClassTrip: The one to Hokkaido, where Arimi and Ginta start their OperationJealousy.
* CleaningUpRomanticLooseEnds: If you go after either Yuu or Miki, it's highly likely you'll team up with someone else... and you guys will fall in love between yourselves.
* ClingyJealousGirl - CrazyJealousGuy: ''Lots''. There's Miki and Yuu around eachother, Suzu, Jinny, Arimi around Yuu. Kei, Ginta, and Michael around Miki. Satoshi around Meiko, etc.
* CoolBigSis: Doris from the American arc. She's not really happy about it, since it works against her in the romance field: men, and specially her crush, only see her as a friend and not as a prospect girlfriend. [[spoiler: She has to prety much spell her intrest to Brian after Jinny and Bill get hitched.]]
* CoolDownHug: Miki to Yuu as he turns to leave, angry at her avoiding him.
** She does this again while he takes comfort in her embrace, thoroughly shaken up by the [[spoiler: dead-end search for his real father]].
* {{Crossdresser}}: Just once, [[CrowningMomentOfFunny but it's memorable]]: [[spoiler: Yuu has to crossdress for a TV commercial with idol Suzu Sakuma and he hates it. No one outside of Yuu and Suzu's social circle knows Yuu is "the tall girl"; Ginta even openly comments on how attractive "she" is ''in front of Yuu''.]]
* DeadpanSnarker: Yuu, in the beginning.
* DefeatMeansFriendship: As demonstrated by Yuu and Miki's huge circle of friends by series' end. It comes with the bonus that sooner or later [[CleaningUpRomanticLooseEnds said defeated romantic rivals]] [[PairTheSpares end up meeting their perfect matches]].
* DoggedNiceGuy: Poor Satoshi. He's the most popular guy in the High School and he has to fall in love with the one girl that's not interested on him. [[spoiler: He tries - persistently - to become the ReplacementLoveInterest for Meiko and, in fact, almost does. When it's clear Meiko is very much in love with Namura he more or less gives up quietly.]]
* DudeShesLikeInAComa: Subverted: Miki was ''pretending'' she was unconscious when this happened, hoping Yuu wouldn't tease her for a recent and embarrassing accident. It didn't work, obviously.
* EducationMama: ''Both'' of Kei's parents. This drives him to stop playing the piano and run away from home.
%%* {{Eagleland}}: The Americans, specially Michael.
%%* ElaborateUniversityHigh: Two of 'em.
* ExpositoryHairstyleChange: Anju Kitahara used to have long hair as a pre-teen girl, but when we see her for the first time, she's already keeping it much shorter. Also, Meiko has straight hair, but she starts perming it after she starts going out with Namura
* FirstGirlWins: Subverted: Arimi and Anju actually are first girls who knew Yuu from before he met Miki, yet Miki is presented first in the series and she ends up winning.
* FirstKiss: What Yuu took away from Miki in their DudeShesLikeInAComa moment.
* FlirtyStepsiblings: The point of the whole series.
* ForcefulKiss: Ginta on Miki in episode 3, and later Michael on Miki too, in episode 58.
* GodCreatedCanonForeigner: All major American characters in the anime adaptation along with Anju Kitahara were all happily created by [[WordOfGod Wataru Yoshizumi]] ''herself'' (and on her own terms, no less) based on the request from the animation staff to further develop Miki and Yuu's characterizations. The only disappointment Yoshizumi had for the anime was [[TheFashionista Jinny's]] lack of style variety, due to the anime staff not wanting to pull the [[DoingItForTheArt effort]] in giving her the variety of hairstyles nor clothing styles Yoshizumi wholeheartedly designed for her.
* HappilyMarried: {{Subverted}} in the 13-years-later sequel ''Marmalade Boy Little'' (2013), the legendary couple Yuu and Miki have been together for over a decade and a half but have been too preoccupied with their work and siblings to get married, although they might as well be. This changes when Satoshi points it out and gives a mild lecture to Yuu about responsibility. Yuu proceeds to think seriously about it immediately and ends up proposing to Miki, who cries.
** Jin and Chiyako, Youji and Rumi. Even before they swapped partners, the couples seemed to be fairly happy.
** More than that: they're quite happy to, all four plus the respective children, live together in the same house, and spend their free time together. And they even refer to themselves collectively as the parents of Miki and Yuu.
*** Miki may be just a touch more GenreSavvy than she lets on; after she warms to the spouse-swapping, she is heard calling her parents' new spouses "Chiyako-mama" and "Youji-papa" in the subtitled version.
** As unconventional as the Koishikawa/Matsuura marriages are, they seem to be the only one shown in-series to be happy. [[spoiler: (The weddings of Namura and Meiko, and Yuu and Miki, in the series finale, notwithstanding.)]] Meiko's parents are shown to be unhappy and unfaithful (and for added drama, Mrs. Akizuki is a LadyDrunk), and Satoshi's father's chronic philandering seems to have put noticeable strain on his marriage (not to mention his relationship with his son).
* {{Hikikomori}}: Yuu ''almost'' became one at age 12, spending a month locked in his room [[spoiler: after finding out by accident that Youji might not be his biological dad.]].
* HotBlooded: Ginta and Rokutanda are the SliceOfLife {{Shojo}} version of this.
** Also, the two Grant brothers. Michael is more of a Genki Guy, tho.
* HotForStudent Namura-sensei and Meiko are among the very rare cases where this situation is protrayed ''sympathetically''.
* HumiliatingWager: Tsutomu loses a tennis match, and as punishment has to shave his head.
%%* IWantMyBelovedToBeHappy: Anju, Satoshi, Ryouko-sensei [[spoiler: and Kei in the anime]].
* IllGirl: Anju, who has a weak heart [[spoiler: and almost dies at one point]].
* ImportantHaircut: After their big misunderstanding over her love letter, Meiko jokely suggests that Miki [[InvokedTrope invoke]] this right before it is revealed that Ginta cut his hair to apologize to Miki. After [[spoiler:Yuu dumps her, so does Miki to try get over herself: her shoulder-length hair becomes a bob that same day.]]
* InkSuitActor: Subverted. The older fanbase would often state the level of similarities between Bill and Brian's character design to [[Creator/NobuyukiHiyama Hiyama]] and [[Creator/ToshiyukiMorikawa Morikawa]]'s own persona, but this is coincidental. Interesting to note though, this pair's relationship is by far the closest in resemblance to the seiyuus themselves.[[note]]We dare you to check their tropes.[[/note]]
%%* InnocentCohabitation: Miki and Yuu.
* ItsNotYouItsMe: Invoked by [[spoiler: Namura, when he leaves Meiko since he'll just stunt her life]] and by [[spoiler: Yuu, when he dumps Miki believing they're half siblings]]. There's a major difference, though: the first straightforwardly says "this won't work so please move on and be happy", while the other CannotSpitItOut.
* JapaneseSchoolClub: Several, actually. Miki and Ginta are members of their school's tennis teams and so is Tsutomu, Meiko is in the literature club, Satoshi's friend Furutachi is in the broadcasting club, and Arimi is the star of her school's track team.
* JerkJock: Brian, in his first appearance. But soon, DefeatMeansFriendship and he becomes a HotBlooded JerkWithAHeartOfGold.
* JerkWithAHeartOfGold: Arguably, the majority of the cast qualify for this (albeit with varying degrees of "jerk"). Notable exceptions include Jin, Rumi, Youji, Chiyako, Akira, Anju, Yayoi and Kijima (who omit the "jerk") and Meiko's parents, as well as Satoshi's dad (who omit the "heart of gold").
* JustAKid: Miki discards Michael because she sees him this way. Michael does NOT approve. In the manga, this is also how she treats Kei, scolding him for being immature and nagging him to go back to school.
** She does that in the anime too, to the degree of ''slapping'' Kei when he goes too far.
* KarmaHoudini: Mr. Miwa, Satoshi's famous architect dad. Notorious for womanizing, [[spoiler: he not only exhibits little shame about his chronic unfaithfulness, but has the gall to grouse about ''not'' being able to nail Yuu's mom.... while ''his own son'' is sitting in front of him.]] And the deal is borderline PlayedForLaughs in TheReveal moment itself, FaceFault and funny faces included.
%%* {{Kawaiiko}}: Miki, Suzu.
* {{Leitmotif}}: "[[http://www.youtube.com/watch?v=wRDqSv3smsg Moment]]," by Miki's [[Creator/MarikoKouda very own seiyuu.]] The series' music of choice for moments of tension, catharsis, and romantic drama. Frequently, the last piece of music in an episode.
* LethalChef: Miki's mother Rumi is ''infamous'' for her bad cooking.
* LongDistanceRelationship: Miki and Yuu try this in the anime, when he goes to the USA. [[spoiler: It... doesn't work.]]
* LoveDodecahedron: So many love triangles it's confusing.
* LoveLetterLunacy: Part of the BackStory: Miki writes Ginta a love letter, and sticks it in a magazine in his bag. This magazine was actually borrowed from another boy, so the owner takes it out and reads the letter, humiliating Ginta, who [[SheIsNotMyGirlfriend vehemently denies any feelings for Miki]], claiming she's one of the guys. Miki and Meiko, of course, came back to get something and heard every word...
* LukeYouAreMyFather: By Yuu, ''repeatedly''. [[GenreBlind He really ought to know better by the third time...]]
%%* {{Meganekko}}: Chigusa, Miki and Meiko's school friend.
* TheMinnesotaFats: Miki and several of her love rivals, specially Arimi and Suzu.
* MistakenForGay: Hilariously done with Satoshi and Yuu. [[spoiler: Satoshi spends some episodes pretending to have the hots for Yuu, to cover up their investigations about their possible common past and Satoshi's own feelings for Meiko; it works so well that Miki sees Satoshi as another rival for Yuu's affection, and at the same time Meiko seems to ship them a bit]].
** [[spoiler: Bill, who spends most of the last third of the anime thought to be a StraightGay, but ends the series dating Jinny. So yeah, he's somewhat of a CampStraight instead.]].
* NewOldFlame:
** [[spoiler:Miki and Yuu's parents, for each other. Miki's dad dated Yuu's mom, broke up with her, married Miki's mom and they had Miki, then divorced her in friendly terms and got back together with his old girlfriend. Exactly the same case with Yuu's dad and Miki's mom. (Except for Chiyako's miscarriage.)]].
** For some ''real'' recursion, some [[http://www.fanfiction.net/s/103977/1/Tangled_Skein fanfics]], [[spoiler: set pre-series, actually start with Jin and Rumi, and Youji and Chiyako, as couples ''before'' the "original" couples formed.]]
* NewTransferStudent: Michael, Yuu in regards to the Americans.
* NoodlePeople: Especially in the anime.
* OnlySixFaces: Several characters have pretty much the same features.
* OOCIsSeriousBusiness: Yuu is pretty much a chill guy: during most of the manga, the only emotions he displays are contempt, [[StepfordSmiler happiness]] and, sometimes, moderate anger. Because of this, when near the end of the anime he breaks up with Miki and she, very calmly and with a very, very sad voice, asks basically what has gone wrong and he '''explodes''' [[CryCute crying]] and yelling at her, it's a very powerful moment. Of course, he does this because he thinks he's found out [[spoiler: he and Miki are half-siblings]].
** Also, Miwa - he's usually the more mature guy of the cast, and when's he's not the VoiceofReason he's being the PluckyComicRelief. But when his crush Meiko comes crying [[spoiler: because Namura just left her]] he snaps, goes all the way to Hiroshima and gives him the beating of his life.
* PairTheSpares: Ginta and Arimi, Kei and Suzu.
** The anime [[UpToEleven takes this to dizzying heights]]. [[spoiler: In addition to the above, we have: Tsutomu and Yayoi, Ryouko and Akira, Brian and Doris, and Bill and Jinny. In addition, Michael and Anju are heavily hinted at]]. The only character [[spoiler: who ends the series alone, amazingly, is ''Satoshi'' (although, to be honest, [[ChickMagnet it's hard to imagine him having trouble attracting interest]])]].
*** [[spoiler: And Satoshi is married and has a daughter in the sequel manga, surprising just about no one.]]
%%* PinkySwear
%%* PoorCommunicationKills: The source of many problems for Yuu, Miki and others.
* RomanticTwoGirlFriendship: Miki and Meiko give small vibes at the beginning.
* SayItWithHearts: Parodied. Miki's parents announce "We're getting a divorce! ♥" and she is absolutely pissed that they could say that with a heart mark.
%%* SchoolFestival
%%* SecondEpisodeMorning
* SecretKeeper: Yuu, for [[spoiler: Meiko and Namura. He catches them kissing but keeps his trap shut even in regards to Miki.]].
%%* SecretRelationship: Meiko and Natchan, Yuu and Miki.
%%* {{Sentai}}: Brilliantly parodied in TheMovie.
%%* SchoolNewspaperNewsHound: Miwa's friend Furutachi.
* ShipperOnDeck: [[spoiler:Suzu]], in the manga. She didn't want Yuu for herself there, but wanted to hook him with [[spoiler:Meiko]]. Possibly a ShoutOut to Yoshizumi's earlier shipping plans.
** By the end of the anime, [[spoiler: literally the ''entire supporting cast'' ships Yuu and Miki.]]
** Also, Miki and Yuu ship [[HotForStudent Namura/Meiko.]] Though their deal is quite more complicated: Yuu found out first and wasn't impressed but still became their SecretKeeper, [[spoiler: but Miki found out ''only'' when their cover was blown to someone else and had an HeroicBSOD since it deeply shook Miki's faith in Meiko due to her not trusting Miki enough to tell her.]]
** Tsutomu, once he stops being Arimi's DoggedNiceGuy, openly supports her and Ginta. In the anime, he goes as far as [[spoiler: giving a WhatTheHellHero speech to Miki when Gint and Arimi have a fall-out due to Ginta neglecting his girlfriend to support the ''very'' distraught Miki (to be fair, Miki ''does'' have pretty good reasons to be depressed, though Tsutomu doesn't know), so it's up to them and Yayoi to fix it.]]
* {{Shojo}}: Arguably, one of the defining examples of the romantic comedy variation of the demographic.
* ShortAnimeMovie: TheMovie is the length of a regular episode
%%* {{Shorttank}}: Miki. Also, Anju when she was young.
* ShrinesAndTemples: The New Years episode.
* SingleTargetSexuality: The series constantly proves that Yuu and Miki are unable to look at anyone but each other.
* SlapSlapKiss: Yuu and Miki started like that. [[spoiler:Suzu and Kei are once or twice hinted to ''possibly'' end up like this, and they end up dating each other in the sequel]]
* SpoilerOpening: The ''very first shot'' is of Yuu and Miki kissing. ''Gosh, I wonder who she's gonna choose?!'' That there is a scene later in the sequence of Miki standing between Yuu and Ginta, looking adorably confused, does not help.
** That's because that one is the ''second'' opening, supposed to air when they are already together anyway. For some reason they decided to skip the first Japanese opening, perfectly spoiler free.
** Arguably worse were the [[EyeCatch Spoiler Eyecatches.]] Every triangle on the show showed up in at least one, complete with the resolution, and they almost always showed up long before the actual resolution took place.
* StalkerWithACrush: Yuu to Miki, following her around before even meeting her in the anime, and in the manga constantly popping up where she is, especially while she is avoiding him due to hurt.
** Kei's rather possessive of Miki, as she's one of his very few friends, and he does some serious work towards isolating her from Yuu. Anime only characters Michael and Jinny arguably qualify, as well as anime!Suzu. Satoshi is a more gentle version of this trope in regards to Meiko.
* StepfordSmiler: Yuu. He's a pretty chill, apparently carefree guy, but deep down he's got issues. Picture a slightly older [[Manga/KodomoNoOmocha Hayama]] that has been brought up by a loving family (in fact, both even look quite a bit alike). Watch the movie, and compare [[spoiler: Yuu's treatment of Miki throughout the first third of the series with the fact that, before he ever met her, he spent an entire day following her around town.]] This makes ''Marmalade Boy'' an instance of a StalkerWithACrush being [[spoiler: the ''male protagonist''.]]
* SugarAndIceGuy:
** Yuu starts as this, hiding his feelings for Miki and his thoughts on the parental deal under his DeadpanSnarker facade. He aknowledges it as well when he confesses this to Miki, openly saying he liked how open she was on her disapprovement while he just couldn't spit it out.
** Meiko has a touch of this, as well: she's very reserved and while Miki confides in her, she rarely confides ''back''. Miki knows about the difficulties in her home life, but Meiko plays the StepfordSmiler if she gets too depressive about it. She cares a lot about Miki, gives her excellent advice, but she says once that she doesn't want the kind of friends that force her to spill her guts about everything. While Miki initially misunderstands this, she later clarifies that she admires Miki's openness and honesty, but she can't be the same way, and it's a bit of a shock to watch her breakdowns over Namura as a result, which forces Miki, for once, to be the shoulder Meiko cries on instead of the other way around.
* ThrowTheDogABone: In the anime, Tsutomu meets Yayoi and ends up dating her.
* TitleDrop: In the second episode of the anime, Miki makes a joke comparing Yuu to marmalade, and thus calls him "marmalade boy".
%%* TomboyAndGirlyGirl: Miki and Meiko. Later, Miki and either Arimi or Anju. Also, Jinny and Doris.
%%* TwistedKneeCollapse: Miki, at least twice.
%%* TwoTeacherSchool: Namura, Ryouko, Kyoto-sensei and the Principal seem to be the only ones.
%%* UnluckyChildhoodFriend: Ginta, Arimi, Anju, Kijima, Ryouko.
* UnrequitedLoveSwitcheroo: Subverted: Miki only ''thought'' her love was unrequited, because of the LoveLetterLunacy detailed above. Ginta actually loved her all along, but she got over him after the whole mess.
%%* YamatoNadeshiko:
%%** Anju, voiced by Creator/KikukoInoue.
%%** Also, Ryouko Momoi.
