!The Koishikawa/Matsuura household
[[folder:Miki Koishikawa]]
[[caption-width-right:300:The lovable stepsister]]
->Voiced by: Creator/MarikoKouda (JP), Creator/MichelleRuff (EN), Laura Orlazábal (Latin-American Spanish), Amalica Cantadero (Spaniard Spanish)

* {{Adorkable}}: She's a total dork, and we love her for that.
* BadLiar: Generally is so, and she fails at hiding the fact that she was awake when Yuu kissed her.
* BoyishShortHair: She had this when she was in middle school, and even then she was an avid tennis player. When Meiko suggests she cut her hair after Ginta rejects her, she jokes she wouldn't have any left.
* BroodingBoyGentleGirl: Yuu is mostly a cool and collected guy, but sometimes he's prone to 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 doesn't.
* ButtMonkey: Specially to Yuu.
* CoolDownHug: Gives this to Yuu after he begins to walk away while evidently upset at her avoiding him.
* CryCute
* DudeMagnet: Attracts several boys in the series.
* FlirtyStepsiblings: With Yuu, it's the point of the whole series.
* GenkiGirl: She's a lively and cheerful girl.
* GirlNextDoor: Of the stepsister variant, to Yuu.
* HeroicSelfDeprecation
* HeWillNotCrySoICryForHim: Cries for the distraught Yuu at the beach while holding him to her chest.
* IWillWaitForYou: To [[spoiler:Yuu]].
* {{Kawaiiko}}: She mixes this with some {{Shorttank}} traits.
* LoveConfessor: Regarding Yuu, until [[spoiler:[[IgnoredConfession he confesses to her a second time]]]].
* LoveMartyr: To a degree, towards Yuu.
* ObliviousToLove: She completely misreads Kei's intentions, leading a jealous Yuu to fight with her. Not to mention how she fails to even register [[ForeignExchangeStudent Michael]]'s StalkerWithACrush feelings towards her. Also, despite being in love with him, she was even oblivious to Yuu's feelings towards her until he spelled it out for her.
* PassionateSportsGirl: To a small degree. She's very athletic and a member of the school's tennis team, not to mention she's a rather decent player in her own.
* PluckyGirl: Ditzy as she is, she can also be pretty stubborn, e.g. in the anime she's the one who convinces Meiko to [[spoiler:go to Hiroshima and confront Namura.]]
* SavvyGuyEnergeticGirl: Energetic Girl to Yuu's Savvy Guy.
* SheCleansUpNicely:
** Although initially regarded as plain and not beautiful ''enough'', true to shoujo manga tropes, Miki is still evidently very pretty, judging by her popularity that was enough to make [[UnLuckyChildhoodFriend Ginta]] afraid of telling other guys that he liked her, not to mention that the mangaka Yoshizumi Wataru based her looks off a ''magazine it girl''.
** Noted here and there in the manga, like when Yuu says she looks cute in the dress she buys from his workplace. Is noted by Arimi as well when she sees Miki with her hair down for once, and definitely by Kei (and Michael, in the anime) who fall head over heels for her [[LoveAtFirstSight at first sight]].
** Over a decade later, Miki is drawn as pretty and cute even into her thirties, inside of the 2013 sequel series, ''Marmalade Boy Little''.
** Also, despite how simply Miki dresses in the manga, the mangaka frequently draws her [[ looking cute in pretty clothes]], and [[ with a pretty face]].
* {{Shorttank}}: While she has a prominent feminine side, she's a bit of a tomboy, a GenkiGirl, and quite athletic.
* 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.
* SuddenlySHOUTING!: Has a penchant to do this when startled.
* SunnySunflowerDisposition:
** [[ And]] [[ how]].
** In the scene near the end where Yuu yells at her [[spoiler: asking her not to love him anymore]], she changes the subject and goes off happily to look at a garden of sunflowers by someone's house. Yuu quickly sees that she was trying not to let him see she was about to cry.
* TomboyAndGirlyGirl: She could be seen as the tomboy to Meiko, Arimi and Anju's girly girls, although she does not feel one way or another about the subject.
* TomboyishPonytail: She has it in her high school days.
* TomboyWithAGirlyStreak: She may be a ShortTank with TomboyishPonytail, but still a huge girly girl at heart.

[[folder: Yuu Matsuura]]
[[caption-width-right:300:The enigmatic stepbrother]]
->Voiced by: Creator/RyotaroOkiayu (JP; debut role), Creator/MichaelLindsay (EN), Jorge Araneda (Latin-American Spanish), Iván Jara (Spaniard Spanish)

* AcademicAthlete: Yuu is smart and naturally athletic, being able to excel in almost every sport although he did not join any clubs in order to focus on his studies.
* AnguishedDeclarationOfLove: The second time he confesses to Miki, [[spoiler: unable to take his act of pushing her away anymore because he was under the impression that [[SurpriseIncest they shared a biological father]]]].
* {{Bishounen}}: He's ''very'' pretty-looking.
* BoyNextDoor: Literally, and of the stepbrother variant, To Miki.
* BreakHisHeartToSaveHim: Break Her Heart to Save Her, in his case.
* 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 doesn't.
* BrotherSisterIncest: He loved Miki so much he had been willing to [[spoiler: commit this by the end, felled under the false impression that they were siblings related by blood]].
* CelibateHero: He refused to date with any girl who ever confessed to him. Arimi was the exception as she convinced him to give her a chance, but he still rejected her after a few months containing unbelievably chaste dates. He proudly admits to Miki that his first kiss was with none other than her.
* ChickMagnet: The Anime plays this UpToEleven in the most annoying ways possible. In the manga, he certainly is one, but more tastefully so.
* CovertPervert: With Miki.
** He asks her to sit between his legs on his bed, after she shows off her new uniform with a very short skirt.
** How eager he is for their trip together. Sure, he appears to be mildly looking forward to it, but for ChasteHero Yuu who mostly hides his true feelings, that sort of behavior holds much more meaning than it normally would.
** Upon finding Miki in the infirmary bed a second time, he proceeded to literally ''climb over her'' on the bed and tried to kiss her, all while the poor girl is hiding her mouth under the covers.
* DarkAndTroubledPast
* DeadpanSnarker: In the beginning, he teases Miki a lot.
* FlirtyStepsiblings: With Miki.
* GoodIsNotSoft: Although overly indulgent with Jinny's clingy behavior towards him, possibly due to his own confidence in his SingleTargetSexuality towards Miki, as well as the Anime's struggles with proper characterization (As Yuu is an entirely different character in the manga) he firmly tells her to back off or else when she insults Miki.
* HeroicBSOD: Actually ''[[CryCute cries]]'' when he [[spoiler: comes under the belief that Miki is his biological sister]]
* {{Hikikomori}}: Was this close to cross the DespairEventHorizon and become this [[spoiler: after he finds a letter insinuating that he's an illegitimate child]]
* IgnoredConfession: His confession to Miki, at first.
* ItsNotYouItsMe: When he [[spoiler:breaks up with Miki, despite still loving her and wanting her badly, because he (mistakenly) thought he found out that they were siblings.]]
* JerkWithAHeartOfGold: A unique kind. Yuu is generally polite and sweet, but like Miki says, he actually has some quite bitter points. He especially liked to bump into Miki and trip her up, before he admitted he loved her and couldn't very well treat his girlfriend like that anymore, though he still teased her relentlessly. Underneath it all however, he is a good boy who has almost an unhealthy martyr complex.
* MartyrWithoutACause
* MyGirlIsNotASlut: In defense of Miki when Jinny badmouths her in order to get Yuu to cheat on Miki with her.
* NewTransferStudent: In the anime he leaves to attend St. Andrews high school near New York City to study it there.
* NotBloodSiblings: Confirmed finally to his immense relief, although by the end he had been willing to [[spoiler: be with and marry Miki even while believing she was his half sibling.]]
* PoorCommunicationKills: His FatalFlaw. He also falls in the trap many, MANY times.
* SavvyGuyEnergeticGirl: Savvy Guy to Miki's Energetic Girl.
* SecretKeeper: For [[spoiler: Meiko and Namura, after he caught them kissing in the library.]]
* SingleTargetSexuality: Regarding Miki.
* SlapSlapKiss: Yuu and Miki started like that.
* StepfordSmiler: 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.]]
* SugarAndIcePersonality: Yuu starts as this, hiding his feelings for Miki and his thoughts on the parental deal under his DeadpanSnarker facade. He acknowledges it as well when he confesses this to Miki, openly saying he liked how open she was about her disapproval while he just couldn't spit it out.
* StalkerWithACrush: To Miki, shown in the movie.
* TranquilFury: Doesn't get angry often, but when he does, it's this.
** Miki is visibly scared of him when he corners her in the aftermath of her avoiding him, Yuu being visibly upset and then unsettled at her changing her sweet and lovable attitude in his presence.
** To Jinny, when she implies that he should break up with Miki and choose her.
* WhatTheHellHero:
** Meiko invokes this towards him when he misses too many calls from Miki, and hears that he also supposedly slept with Jinny.
** He later invokes this to his and Miki's parents, under the belief that they [[spoiler: hid the fact that Yuu and Miki were biological siblings]], leaving the step siblings to fall in love too deeply to separate anymore.

* AmicablyDivorced: With Youji, after their divorces and remarriages.
* ConvenientMiscarriage: [[spoiler: Was pregnant with Jin's baby before marrying Youji, but it was a stillborn. Her mother wrote a rather confusing letter about it to her... Yuu found it and mistakenly thought it referred to him.]]

!The Akizuki household
[[folder:Meiko Akizuki]]
->Voiced by: Creator/WakanaYamazaki (JP), Creator/KateHiggins (EN), Keyros Guillén (Latin-American Spanish), Julia Martínez (Spaniard Spanish)

* AdaptationalJerkass: While ''not'' a bad person in any way, Meiko is much pushier and snarkier (sometimes being pretty mean) in the anime.
* BadassAdorable: 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.
* BrainyBrunette: Extremely booksmart, member of the literature club ''and'' the student council.
* BrokenBird: [[spoiler: Her family life is troubled because her parents are unfaithful to each other and constantly argue.]]
* HonestAdvisor: To Miki. She's very level-headed, and outright laughs at her when Miki asks her about her supposed date with Yuu. Meiko is usually the one pointing out that Miki's soap opera problems aren't as bad as they could be. She's the voice of reason whenever Miki gets a little caught up in her own drama.
* MayDecemberRomance: Lampshaded when she and Namura got together.
-->'''Namura''': "And I'm 8 years older than you.... oh boy."
* {{Ojou}}: She fits the basic character type, though not the full stereotype: she has lighter hair and isn't a member of the Student Council (one of her love interests is the council president, though).
* StarCrossedLovers: Her and Namura. [[spoiler: Until almost the end.]]
* SugarAndIcePersonality: She's sugar to Miki and Namura and her friends, but she can flip the ice switch pretty quickly. Even with Miki, she's very reserved and prefers to focus on Miki's issues rather than her own.
* TeacherStudentRomance: Meiko and Namura are among the very rare cases where this situation is portrayed sympathetically.
* TomboyAndGirlyGirl: The girly girl to Miki's tomboy.
* {{Tsundere}}: For Satoshi, in the anime.

[[folder:Meiko's parents]]

* LadyDrunk: Meiko's mother is seen once drowning her sorrows while verbally fighting with her much-hated husband.
* ParentalMarriageVeto: [[spoiler:In the anime, when Meiko and Namura get together again, they refuse to let them meet up.]]
* ParentalNeglect: They don't beat up Meiko, but are almost criminally neglectful of her. If not for their maid, Meiko would be all alone at home.
* YourCheatingHeart: Both of them. The only reason they're not already divorced is that the Akizuki's wealth would be lost.

[[folder:The Akizuki Maid]]
->Voiced by: Yuka Ohno (JP), Creator/CindyRobinson (EN)

* NoNameGiven
* ParentalSubstitute: Treats Meiko with all the love and care her parents don't give her.

* BigBrotherMentor
* ChildhoodFriendRomance: He has been in love with Miki since junior high.
* CoolTeacher: [[spoiler: Is a teacher at Toryo Junior High in the sequel, largely serving the narrative role of Namura, except without the student romance. His students even call him "Gin-chan"!]]
* CrazyJealousGuy: When it comes to Miki.
* FamilyVersusCareer: [[spoiler: In the sequel, Ginta's desire for a family clashes with Arimi's driven career path, nearly leading to divorce; it naturally turns out to all be a case of PoorCommunicationKills, albeit one that lasts ''three years''.]]
* ForcefulKiss: On Miki, once. She slapped him away.
* HotBlooded: The SliceOfLife shojo version of this.
* NoIndoorVoice: More than once, Yuu tells him to quiet down as the whole neighborhood can hear him. And then we meet Tsutomu...
* OperationJealousy: With Arimi. [[spoiler: And then, they fall for real.]]
* PairTheSpares: [[spoiler: Eventually hooks up with Arimi, and marries her in the sequel.]]

[[folder: Shinichi Namura]]
->Voiced by: Creator/ToruFuruya (JP), Creator/SkipStellrecht [[note]] credited as Jack Aubree [[/note]] (EN), Pablo Ausensi (Latin-American Spanish)

* BigBrotherMentor
* CoolTeacher: Affectionately known as "Na-chan" by his students
* InSeriesNickname: "Natchan"
* JerkassFacade: Would rather act cold to Meiko and tell her he and Ryoko are dating, than have the poor girl face all kind of problems because of him. [[DieForOurShip Too bad the rabid Satoshi/Meiko fans refuse to see it]].]]
* MayDecemberRomance: Lampshaded when he and Meiko got together.
-->'''Namura''': "And I'm 8 years older than you.... oh boy."
* OlderThanTheyLook: Meiko thought he was a student at first.

* AloneAmongTheCouples:
** [[spoiler: The only character who ends the series alone (although, to be honest, it's hard to imagine him having trouble attracting interest).]]
** [[spoiler: Averted by the sequel, as he's now HappilyMarried and dotes on his daughter.]]
* AscendedExtra: Got ''far'' more screentime in the anime.
* BigBrotherMentor: For both Yuu and Miki. [[spoiler: This continues through to the sequel, where he's the one who finally pesters them to get married, 13 years later.]]
* BrilliantButLazy: [[spoiler: Shades of this the sequel, where he shoves paperwork onto Yuu in order to spend more time with his daughter; considering they're business partners in a successful architectural firm, it's probably just him being TheTrickster as always.]]
* ChickMagnet: Although he only has eyes for Meiko.
* HopelessSuitor: To Meiko. Come ''on'', Miwa. Why are you after one of the few girls who doesn't like you that way?
* JerkWithAHeartOfGold: Loves pranking and snarking at people, but is a loyal friend when his "victims" need it.
* ShipperOnDeck: Yuu may find his pranks annoying, but may never find a better wingman, especially in the anime.

* TallDarkAndSnarky: He has the look and the snarky personality.
* TheTrickster: He likes pranking people.

Leader of the broadcasting club.

* NerdGlasses
* NiceGuy: When not in "journalist" action
* SchoolNewspaperNewsHound: Which brings Miki and Yuu a lot of trouble [[spoiler:when he takes pics of Miki and Yuu's recently re-married parents, revealing them as swingers]].

[[folder: Kyoto-sensei]]

* MoralGuardians: Threw quite a fit when she found out [[spoiler:about the Matsuuras and the Koishikawas being swingers]].
* NoNameGiven: "Kyoto-sensei" is her title and position in the school itself. (She is the vice-principal.)

* ReasonableAuthorityFigure

!Other students
[[folder: Arimi Suzuki]]
->Voiced by: Creator/AyaHisakawa (JP), Creator/CarrieSavage (EN), Rosario Zamora (Latin-American Spanish), Pilar Domínguez (Spaniard Spanish)

* AdaptationDyeJob: Brown hair in the manga, green hair in the anime.
* AmicableExes: 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.
* ChildhoodFriendRomance: The unlucky version with Yuu.
* ClingyJealousGirl: When it comes to Yuu.
* DudeMagnet: She has many admirers at her school and even her own fan club.
* FamilyVersusCareer: [[spoiler: In the sequel, Ginta's desire for a family clashes with Arimi's driven career path, nearly leading to divorce; it naturally turns out to all be a case of PoorCommunicationKills, albeit one that lasts ''three years''.]]

* TheChewToy: Poor guy never had a chance with Arimi.
* DoggedNiceGuy: To Arimi.
* HopelessSuitor: Has always been this to Arimi.
* HotBlooded: Like his cousin, he's the SliceOfLife shojo version of this.
* LargeHam: Loud, HotBlooded, and has NoIndoorVoice.
* ShipperOnDeck: Once he stops being Arimi's DoggedNiceGuy, openly supports her and Ginta. In the anime, he goes as far as giving a What the Hell, Hero? 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.
* SmallNameBigEgo: He has a habit of making challenges to Ginta or Yuu or both of them together. He always loses, and has to shave his head.
* ThrowTheDogABone: In the anime, he not only is more sympathetic and comes to support Ginta and Arimi, but he gets a girlfriend too. Lampshaded by the author in the last volume omake: when talking about her characters, she said that she felt sad some of them weren't able to achieve happiness and she accompanied this with a drawing of Satoshi looking dejected and Rokutanda saying "At least I've got a girlfriend in the Anime"
* YouGottaHaveBlueHair: In the anime he has purple hair.

* CrazyJealousGuy: Maybe the worst among Miki's suitors in regards to this.
* ElegantClassicalMusician: Plays the piano beautifully.
* JustAKid: Miki thinks so. He's ''very'' unhappy about that.
* KickTheDog: [[spoiler: Hiding Miki's medallion (or bracelet, in the manga), then giving it to Yuu and saying ''that she threw it away because she doesn't like him anymore''. Yuu isn't fooled, but it still brings a huge rift between them.]]
* PairTheSpares: [[spoiler: Has been dating Suzu by the sequel.]]
* PeerlessLoveInterest: Sees Miki as this.
* StageMom: ''Both'' of his parents were this. He ran away from home because of their pressure on him. [[spoiler: They get better.]]
* StalkerWithACrush: Rather possessive of Miki, as she's one of his very few friends, and he does some serious work towards isolating her from Yuu.
* TookALevelInKindness: [[spoiler: In the anime, when he re-appears long after his arc is over, he's much more mature and kinder.]]

* ElegantClassicalMusician: Excellent violinist.
* ExpositoryHairstyleChange: Used to have GirlishPigtails, now has very short hair.

* DumbJock: When it comes to love and social relations, he ''really . lacks . tact.'' Brian doesn't get Jinny's clear and constant signal of "[[BigNo NO!]] I don't want to be your girl!" to him and keeps on harassing her, straight-on bullies Yuu just because Jinny wanted to date Yuu instead of understanding Yuu's side of the story, [[spoiler: being [[ObliviousToLove oblivious]] to Doris' attraction ''towards himself'']], and not knowing that [[spoiler: he's the UnwittingPawn of Bill]].
* FieryRedhead
* FunTShirt: A hoodie with "FORCE," a jacket with "Star," and a tee with "CON."
* HotBlooded
* JerkJock: He's the resident bully of whoever gets in his way of getting the girl he wants, unless it's proven that the guy deserves his respect. Good thing he's not on a ShockJock level.
* LovableJock: Once you gain his respect and join his inner circle of friends, you'll see his air-headed silly side more often than not.
* ObliviousToLove: Poor [[spoiler: Doris]]...
* SensitiveGuyAndManlyMan: On the appearance, he's the manly man to Bill's sensitive man. [[MoreThanMeetsTheEye But don't let that fool you]], ''they are [[InvertedTrope inverts]]''. [[note]]Brian can easily turn into a crybaby, while Bill [[RatedMForManly would never show a tear]].[[/note]]
* UnwittingPawn: [[spoiler: Of [[GuileHero Bill]]]]. [[spoiler: Bill knows that befriending Brian is the easiest and fastest path to befriend Jinny, who is Bill's love target. Top with Brian's air-headedness and hostility towards Jinny, [[TheSmartGuy Bill]] leaves Jinny a ''way'' better impression than Brian. Had Bill be more [[ManipulativeBastard aggressive]], Brian can easily be psychologically crushed by him.]]

[[folder: William "Bill" Matheson]]
->Voiced by: Creator/NobuyukiHiyama (JP), Creator/TonyOliver (EN)
* BadassDriver: More pro than Brian, and he would gladly [[UpToEleven level up]] [[spoiler: to DrivesLikeCrazy]] when needed.
* BigBrotherMentor: To Yuu, Jinny, and most likely the childish Grant Brothers.
* CurtainsMatchTheWindow: And in Lavender!
* CampStraight: Most people in his school believes he's gay. Among his circle of friends, only Yuu, Anju, and Doris [[note]]Wasn't shown in story, but the fact that Doris [[spoiler: was never hostile towards Bill over his wide-spread gossip with Brian is more than a solid proof of her understanding]].[[/note]] knows about his true sexual orientation. As for Brian, he wasn't shown to be uncomfortable around Bill, but he's more of a straight-on [[DumbJock air-head]] than to be a person who knows what's going on.
* {{Dandere}}: He has a quiet, observant, and [[InTouchWithHisFeminineSide effeminate]] persona but with a ''very'' [[spoiler: [[RatedMForManly athletic, masculine]], and [[{{Hotblooded}} hotblooded]] [[HiddenBadass inner core]]]].
* DeathGlare: Gave [[spoiler: Jinny]] a loooong one to take warning, and yet she's stupid enough to ''despise it''.
* DoingResearch: Whenever he's free for the night, he would usually stay in his dorm attic to study the stars using his telescope.
* GayGuySeeksPopularJock: What people around him rumored his relationship with Brian was. But this was only the tip of the iceberg of him being actually a GuileHero. See trope below.
* GenreSavvy: Like Anju, [[spoiler: while his ultimate goal is to have Jinny become his girl, he's aware of Brian trying very hard to pursue her, while Jinny's trying to court Yuu, and that he himself might be a HopelessSuitor to her]]. But he just opts to lay back and continue to observe the situation in hopes to have a chance, while at the same time [[spoiler: actively dates Anju]] to have a BirdsOfAFeather friend to talk with.
* GettingCrapPastTheRadar: Did he just slip in the idea of getting "''[[DrinkOrder beer]]'' ?!"
* GoodIsNotSoft: Never ''ever'' take somebody else's feelings for granted in front of him. Did you hear it, [[spoiler: Jinny]]?
* GuileHero: His core motive of befriending Brian was to [[spoiler: get close and befriend Jinny]].
* HollywoodNerd: An effeminate-looking LongHairedPrettyBoy who doesn't hide his taste for fashion, and prefers to stay in his dorm attic researching the stars all night.
* JustFriends: With [[BirdsOfAFeather Anju]].
* LongHairedPrettyBoy: Compared to the majority of the male cast, he's very pretty, with one ear pierced to wear an earring.
* LoveMartyr: To [[spoiler:Jinny]]
* MistakenForGay: But being the [[spoiler: GuileHero]] that he is, he just went with the flow and semi-acted the part. Until Jinny suspected him [[spoiler: dating Anju]].
* MrFanservice: Constant eye winks that flashes BishieSparkle? Check. A [[TheCharmer smooth-talker]]? Double check. A scene of him showing his chest and buttoning up his shirt? ''Triple . Check!''
* NiceGuy: [[BewareTheNiceOnes But that doesn't mean he would allow you to take advantage of him nor allow you to bully his friends however you want]].
* NoSocialSkills: As to what he thinks of himself to be. But the only thing that was actually blocking him was his [[CowardlyLion lack of confidence]].
* OnlySaneMan
* SavvyGuyEnergeticGirl: The savvy guy to Jinny's energetic girl, and it's shown that he's [[RatedMForManly much more in control]] of Jinny than what people around him expected.
* SensitiveGuyAndManlyMan: On the appearance, he's the sensitive man to Brian's manly man. But as you [[MoreThanMeetsTheEye get to know them further]], you'll realize [[InvertedTrope it's the total opposite]].
* TheSmartGuy: It was implied that Jinny would constantly ask him for school notes, and he already has been prepping himself to major in astronomy for college.
* SpellMyNameWithAnS: Although the English dub version went with "Bill" [[note]]Japanese romanization would spell "Bi-ru"[[/note]] for William's short name, his official preference in the original Japanese version is actually "Will" [[note]]Wi-ru[[/note]], which is completely legit in western culture.
* WhatTheHellHero: On Jinny, when he learns about [[spoiler: her terrible prank on Miki.]] He's so [[TranquilFury pissed off]] that not only he calls her an horrible person, but ''he [[spoiler: [[ArmorPiercingSlap slaps]]]] her''.
* YouGottaHaveBlueHair: He has lavender hair.

[[folder: Jinny Golding]]
->Voiced by: Yuka Koyama (JP), Creator/TaraPlatt (EN)
* BeAWhoreToGetYourMan: Attempted with Yuu and failed. Also used this reasoning to blame Miki for it when she lied about [[spoiler: Yuu sleeping with her.]]
* BookDumb: Which is why she always goes to Bill for homework aid. It's not that she doesn't want to do well in school, she just prefers to play more than to sit down and do her homework.
* ClingyJealousGirl: When it comes to Yuu.
* DumbBlonde: More like [[WomanChild "selfish and childish blonde"]] than truly dumb.
* TheFashionista: According to [[WordOfGod Yoshizumi]], Jinny was designed to be a very fashion-forward girl. But the animation staff chickened out of animating the hairstyles and clothing styles Yoshizumi designed for her and just stuck with Jinny's "default look." Which was a shame.
* GreenEyedEpiphany: Towards [[spoiler: Bill]]. Upon noticing him [[spoiler: not being gay and enjoying his alone time with Anju]], she started to [[ItWasWithYouAllAlong panic over her attraction]] to [[spoiler: Bill]], and took the step forward in confronting him, which eventually led to [[spoiler: Bill]] [[PairtheSpares becoming her boyfriend]].
* InformedAttractiveness: This being [[OnlySixFaces anime]], she objectively [[ looks no prettier than Miki]] [[note]] the link is a side by side comparison of Jinny and Miki for reference.[[/note]], and while she clearly isn't drawn with the same care as [[YamatoNadeshiko Meiko]] or Arimi are drawn with, the viewer is left to believe the narration's insistence that she is HotterandSexier than other girls. This could be mostly blamed on the Anime's wonky character design.
* KickTheDog: [[spoiler: Telling Miki that she was Yuu's "other woman", out of jealousy. This makes the ''already'' distressed Miki break up with Yuu in the airport, as she's too emotionally exhausted to handle a LongDistanceRelationship.]]
* LightFeminineAndDarkFeminine. Dark to Doris' Light.
* LovableAlphaBitch: Jinny's not an all-around bad girl to people, just a mischievous pampered girl who crossed the moral line [[spoiler: once]]. Doris and Bill are certainly the two unsung heroes who can truly ''ground'' her.
* LoveAtFirstSight: Towards Yuu, she probably had a thing for [[AsianAndNerdy nerdy East Asians]].
* MyGodWhatHaveIDone: After Bill and Doris express their anger at her [[spoiler: for her treatment of Miki]].

[[folder: Doris O'Connor]]
->Voiced by: Creator/ShihoNiiyama (JP), Creator/JulieAnnTaylor (EN)
* BrainyBrunette: Has light brown hair and is very perceptive and smart.
* ClosetGeek: She may look like a sophisticated lady, but she's a big fangirl of sci-fi movies, and pays a lot of attention to spectacular SpecialEffects, [[spoiler:[[GeekyTurnOn which is one of the biggest reasons why she feels close to Brian in terms of hobbies]]]].
* CoolBigSis: Specially to Jinny, whom she treats like a little sister. She isn't thrilled, however, as men only see her as a friend and not as a prospective girlfriend.
* LightFeminineAndDarkFeminine. Light to Jinny's Dark.
* OnlySaneWoman: Unlike Jinny, she is more down-to-earth and practical.
* SilkHidingSteel: An American and modern version of the YamatoNadeshiko archetype.
* YouthfulFreckles

[[folder: Eddie and Chris]]
* BigBrotherAttraction: Chris, in a child-like way.
* TheCutie: Both of them are ''adorable''
* StreetUrchin

!Marmalade Boy Little

[[folder: Rikka Matsuura]]
Yuu's and Miki's little half-sister. Stepsibling to Saku.
* AlmostKiss: Near the end of her Christmas date with Aoi he leans in to kiss her... only to be stopped by Rikka subconsciously stopping him by putting her hands on his lips. Both of them are very surprised by her actions.
* BigBrotherAttraction: While talking to Mikki about Saku and his apparent feelings for her, Rikka, she states that when she was very little that first love/crush was Yuu and was sad when she found out Mikki and Yuu were together.
* BookDumb: And how! She's at the bottom of her class in middle school, and generally a bit slow on the uptake (as evidenced by her honest belief through elementary school that she had four parents).
-->'''Rikka:''' The ranks for finals will be posted too and I'm sure you'll be number one again!\\
'''Sakku:''' Who knows... what rank were you first term?\\
* ClingyJealousGirl: As she starts to notice Saku as a boy and sees that all the girls are attractted to him, she exhibits slight frustration and sadness, even when he was with his twin cousins.
-->'''Rikka:''' ''[looking at Saku with his twin cousins]'' They adore him... why is Saku always popular with cute girls...
* FlirtyStepsiblings: It wouldn't be Marmalade Boy if they weren't. Complicated by them actually being raised as siblings from birth, even though they are NotBloodSiblings.
* GenerationXerox: Basically, Miki all over again, right down to the habit of SuddenlySHOUTING! when startled; keeps her hair a bit longer, though.
* HeadbuttOfLove: With Saku
* IDidntMeanToTurnYouOn: Happened more than once towards Saku. The last time it happened Rikka is [[HeadButtOfLove very close to his face]] and he steps back trying to remember the promise he made to his parents about his and Rikka's relationship staying pure until collage. He isn't happy about it....
* LikeBrotherAndSister: Averted. As Saku hits his growth spurt, Rikka really begins to notice how good-looking he is.
* ObliviousToLove: Saku isn't exactly quiet about how he feels about Rikka, but it takes her through ''junior high school'' to finally notice.
* ShipperOnDeck: For Emiri and Koudai
* WhenSheSmiles: Saku confesses that he loves Rikka's smile very much and wishes she would always smile like that.

[[folder: Saku Koishikawa]]
Yuu's and Miki's little half-brother. Stepsibling to Rikka.
* {{Adorkable}}: Saku has his moments. It gets even cuter when it is revealed by Rikka that although Saku doesn't show much emotion and mostly has a straight face, he believes that he is showing his emotions properly. [[TheStoic Obviously he isn't]], as seen in a flashback where Saku gets a Christmas present from his parents and doesn't react, which leads them to believe he doesn't like it when he actually does.
* AngerBornOfWorry: He yells at Rikka when she is almost lured in by a pedophile without fighting back much. Needless to say, she was very much surprised as it's the first time he has scolded or yelled at her ever in her life.
* ChickMagnet: Duh.
* ChildhoodFriendRomance: Multiply this by lifelong stepsibling. Eep.
* CrazyJealousGuy: Downplayed and Discussed. Saku is pretty chill while Rikka and Aoi are dating. However, after Aoi and Rikka break up, Saku admits that although [[IWantMyBelovedToBeHappy he thought he was going to okay with it]], he still felt a little bothered by it.
-->'''Aoi:''' Actually I am curious, were you really okay with it when I was dating Rikka?\\
'''Saku:''' I'm okay with it...or so I thought...but to be honest, I wasn't really ok. I didn't like it.\\
'''Aoi:''' ''[Cheerfully]''Oh really? That's what I thought! Sucks for you!
* FlirtyStepsiblings: Effectively SingleTargetSexuality: he is and has always been in love with Rikka, especially since he's well aware they are NotBloodSiblings.
* GenerationXerox: As brooding as Yuu, and just as fixated on his stepsister (Rikka in this case).
* IWantMyBelovedToBeHappy: He turns down Rena's confession and says that although Rikka and Aoi are dating he just likes her and can't go out with Rena while his feelings are so strong. He even reassurances Rikka that he is okay with Rikka and Aoi's relationship after Rikka says she wants him to be happy.
* HeadbuttOfLove: Initiates this with Rikka
* LikeBrotherAndSister: Averted.
* SpellMyNameWithAnS: Early fansubs translated his first name as Hajime, due to the ambiguous nature of kanji readings.

[[folder: Aoi Namura]]
Handsome transfer student from Hiroshima.
* ChickMagnet: Given who his parents are, would you expect any less?
* LateArrivalSpoiler: [[spoiler:His very existence spoils that Meiko and Namura-sensei end up married.]]

[[folder: Rena Sasamiya]]
Saku and Rikka's pretty classmate.
* SpoiledSweet: Has looks, charm, popularity ... and turns out to be actually really, really nice.
