The Koishikawa/Matsuura household

    Miki Koishikawa
The lovable stepsister
Voiced by: Mariko Kouda (JP), Michelle Ruff (EN), Laura Orlazábal (Latin-American Spanish), Amalica Cantadero (Spaniard Spanish)

  • Bad Liar: Generally is so, and she fails at hiding the fact that she was awake when Yuu kissed her.
  • Boyish Short Hair: 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.
  • Brooding Boy, Gentle Girl: 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.
  • Butt-Monkey: Her clumsiness often gets the best of her, especially during physically activity (getting hit with a basketball or even running into a light post). She's also prone to being teased by Ginta, Satoshi and especially Yuu.
  • Cool Down Hug: Gives this to Yuu after he begins to walk away while evidently upset at her avoiding him.
  • Dude Magnet: Attracts several boys in the series.
  • Flirty Stepsiblings: With Yuu, it's the point of the whole series.
  • Genki Girl: She's a lively and cheerful girl.
  • Girl Next Door: Of the stepsister variant, to Yuu.
  • He Will Not Cry, So I Cry for Him: Averted, she cries along with the distraught Yuu at the beach while holding him to her chest.
  • I Will Wait for You: To Yuu after he goes to study abroad.
  • Just a Kid: Her cheerful personality, clumsy nature, and many of her youthful hairstyles all give people this impression of her. This is how she initially compares herself to Arimi after the latter is seen wearing makeup, and is also Jinny's first impression of her. While it's also one thing he loves about her, Yuu even points this out and at one time notes that she would probably be mistaken for a child if she wore a kimono.
    • This is also how she herself feels about both Kei and Michael.
  • Kawaiiko: She mixes this with some Shorttank traits.
  • Love Confessor: Regarding Yuu, until he confesses to her a second time.
  • Love Martyr: To a degree, towards Yuu.
  • Oblivious to Love: She completely misreads Kei's intentions, leading a jealous Yuu to fight with her. Not to mention how she fails to even register Michael's Stalker with a Crush 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.
  • Passionate Sports Girl: 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.
  • Plucky Girl: Ditzy as she is, she can also be pretty stubborn, e.g. in the anime she's the one who convinces Meiko to go to Hiroshima and confront Namura.
  • Prone to Tears: Despite how energetic and, at times, how hot-headed she can be, she's actually pretty fragile and will cry when under enough pressure.
  • Savvy Guy, Energetic Girl: Energetic Girl to Yuu's Savvy Guy.
  • She Cleans Up Nicely:
    • 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 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 at first sight.
    • Two decades 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 Genki Girl, and quite athletic.
  • Single-Target Sexuality: Subverted at first, as before Miki and Yuu get together, her feelings for Ginta began to resurface before ultimately choosing Yuu. Afterwards, the series constantly proves that no matter cute Miki thinks some of the other guys are and how hard anyone tries to push them apart, Yuu and Miki are unable to look at anyone but each other.
  • Slap-Slap-Kiss: Yuu and Miki started like that.
  • Suddenly SHOUTING!!: Has a penchant to do this when startled.
  • Sunny Sunflower Disposition:
    • And how.
    • In the scene near the end where Yuu yells at her 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.
  • Tomboy and Girly Girl: 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.
  • Tomboyish Ponytail: She has it in her high school days.
  • Tomboy with a Girly Streak: She may be a Short Tank with Tomboyish Ponytail, but still a huge girly girl at heart.

     Yuu Matsuura
The enigmatic stepbrother
Voiced by: Ryotaro Okiayu (JP; debut role), Michael Lindsay (EN), Jorge Araneda (Latin-American Spanish), Iván Jara (Spaniard Spanish)

  • Academic Athlete: 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.
  • Anguished Declaration of Love: The second time he confesses to Miki, unable to take his act of pushing her away anymore because he was under the impression that they shared a biological father.
  • Bishounen: There's a reason why so many girls like him, he's very pretty-looking.
  • Boy Next Door: Literally, and of the stepbrother variant, To Miki.
  • Break His Heart to Save Him: Break Her Heart to Save Her, in his case.
  • Brooding Boy, Gentle Girl: 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.
  • Brother–Sister Incest: He loved Miki so much he had been willing to commit this by the end, felled under the false impression that they were siblings related by blood.
  • Celibate Hero: 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.
  • Chick Magnet: The Anime plays this Up to Eleven in the most annoying ways possible. In the manga, he certainly is one, but more tastefully so.
  • Covert Pervert: With Miki.
    • Why does he go off to see Miki during her first tennis match of the school year? Because he wanted to see her in her tennis skirt. While he claims to be joking, remember that this is how he first discovered and fell in love with Miki in the first place, as seen in the movie.
    • 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.
    • He asks her to sit between his legs on his bed, after she shows off her new work 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 Chaste Hero Yuu who mostly hides his true feelings, that sort of behavior holds much more meaning than it normally would.
  • Deadpan Snarker: In the beginning, he teases Miki a lot.
  • Flirty Stepsiblings: With Miki.
  • The Gadfly: He's prone to teasing Miki on a regular basis, sometimes even unintentionally. Episode 11 also shows that Ginta has also become a target of his.
  • Good Is Not Soft: Although overly indulgent with Jinny's clingy behavior towards him, possibly due to his own confidence in his Single-Target Sexuality 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.
  • Heroic BSoD: Actually cries a couple of times in the series, most notably when he comes under the belief that Miki is his biological sister.
  • Hikikomori: Was this close to cross the Despair Event Horizon and become this after he finds a letter insinuating that he's an illegitimate child
  • Ignored Confession: His confession to Miki, at first.
  • It's Not You, It's Me: When he breaks up with Miki, despite still loving her and wanting her badly, because he (mistakenly) thought he found out that they were siblings.
  • Jerk with a Heart of Gold: 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.
  • My Girl Is Not a Slut: In defense of Miki when Jinny badmouths her in order to get Yuu to cheat on Miki with her.
  • New Transfer Student: In the anime he leaves to attend St. Andrews high school near New York City to study it there.
  • Not Blood Siblings: Confirmed finally to his immense relief, although by the end he had been willing to be with and marry Miki even while believing she was his half sibling.
  • Poor Communication Kills: His Fatal Flaw. He also falls in the trap many, MANY times.
  • Savvy Guy, Energetic Girl: Savvy Guy to Miki's Energetic Girl.
  • Secret Keeper: For Meiko and Namura, after he caught them kissing in the library.
  • Single-Target Sexuality: Regarding Miki.
  • Slap-Slap-Kiss: Yuu and Miki started like that.
  • Stepford Smiler: He's a pretty chill, apparently carefree guy, but deep down he's got issues. Picture a slightly older Hayama that has been brought up by a loving family (in fact, both even look quite a bit alike). Watch the movie, and compare 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.
  • Sugar-and-Ice Personality: Yuu starts as this, hiding his feelings for Miki and his thoughts on the parental deal under his Deadpan Snarker 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.
  • Stalker with a Crush: To Miki, shown in the movie.
  • Tranquil Fury: Doesn't get angry often, but when he does, it's usually 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.
  • What the Hell, Hero?:
    • 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 hid the fact that Yuu and Miki were biological siblings, leaving the step siblings to fall in love too deeply to separate anymore.

     Chiyako Matsuura/Koishikawa 
Voiced by: Hiroko Emori (JP), Cindy Robinson (EN), Isabel Quinteros (Latin-American Spanish), Isabel Gaudí (Spaniard Spanish)

  • Amicably Divorced: With Youji, after their divorces and remarriages.
  • Convenient Miscarriage: 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.
  • Cool Big Sis: To Miki, since she doesn't want to be pushy to her.
  • Happily Married: With Jin. Even before they swapped partners, the couples seemed to be fairly happy.
  • Office Lady: She's actually a high-ranked executive in a make-up enterprise.

The Akizuki household

    Meiko Akizuki 
Voiced by: Wakana Yamazaki (JP), Kate Higgins (EN), Keyros Guillén (Latin-American Spanish), Julia Martínez (Spaniard Spanish)

  • Adaptational Jerkass: While not a bad person in any way, Meiko is much pushier and snarkier (sometimes being pretty mean) in the anime.
  • Badass Adorable: 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.
  • Brainy Brunette: Extremely booksmart, member of the literature club and the student council.
  • Broken Bird: Her family life is troubled because her parents are unfaithful to each other and constantly argue.
  • Honest Advisor: 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.
  • May–December Romance: 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).
  • Star-Crossed Lovers: Her and Namura. Until almost the end.
  • Sugar-and-Ice Personality: She's sugar to Miki and Namura and her friends, but around Satoshi, 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.
  • Teacher/Student Romance: Meiko and Namura are among the very rare cases where this situation is portrayed sympathetically.
  • Tomboy and Girly Girl: The girly girl to Miki's tomboy.
  • Tsundere: For Satoshi, in the anime.

    Meiko's parents 
Voiced by: Kiyoyuki Yanada (Meiko's dad, JP), Michiko Abe (Meiko's mom, JP), Richard Epcar (Meiko's dad, EN), Alex Lowell (Meiko's mom, EN)

  • Lady Drunk: Meiko's mother is seen once drowning her sorrows while verbally fighting with her much-hated husband.
  • Parental Marriage Veto: In the anime, when Meiko and Namura get together again, they refuse to let them meet up.
  • Parental Neglect: 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.

Voiced by: Yuka Ohno (JP), Cindy Robinson (EN)


Toryo High School (students and teachers)

     Ginta Suoh 
Voiced by: Junichi Kanemaru (JP), Yuri Lowenthal (EN), Carlos Carvajal (Latin-American Spanish), Jaime Roca (Spaniard Spanish)

  • Childhood Friend Romance: He has been in love with Miki since junior high.
  • Cool Teacher: 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"!
  • Crazy Jealous Guy: When it comes to Miki.
  • Family Versus Career: 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 Poor Communication Kills, albeit one that lasts three years.
  • Forceful Kiss: On Miki, once. She slapped him away.
  • Hot-Blooded: The Slice of Life shojo version of this. While he means well, he can be extremely impulsive, especially towards a girl he likes. He actually punches out Murai, a member of Arimi's fan club, when he believes that he's cheating on her and does the same to a random guy he thinks is harassing her when he was only asking for directions.
  • No Indoor Voice: More than once, Yuu tells him to quiet down as the whole neighborhood can hear him. And then we meet Tsutomu...
  • Operation: Jealousy: With Arimi. And then, they fall for real.
  • Pair the Spares: Eventually hooks up with Arimi, and marries her in the sequel.

Voiced by: Megumi Urawa (JP), Cindy Robinson (EN)

     Satoshi Miwa 
Voiced by: Shinichiro Ohta (JP), Skip Stellrecht note  (EN), José Alberto Sánchez (Spaniard Spanish)

  • Alone Among the Couples:
    • The only character who ends the series alone (although, to be honest, it's hard to imagine him having trouble attracting interest).
    • Averted by the sequel, as he's now Happily Married and dotes on his daughter.
  • Ascended Extra: Got far more screentime in the anime.
  • Beware the Nice Ones: While he's almost always nice, if not a bit a jokester, the only person he's shown to be outright hostile towards is unsurprisingly Namura. On top of clearly being jealous, he believed that breaking up with Meiko and quitting his teaching job were cowardly acts that he made to escape the situation. 31 episodes later, once he learns that he's not only selfishly trying to push Meiko away, but also drags Ryōko into this mess, Satoshi shouts at him that he "deserves to go the hell", gives him a "Reason You Suck" Speech and proceeds to repeatedly punch him out of anger, leaving his face with multiple bruises.
  • Big Brother Mentor: For both Yuu and Miki. Justified in Yuu's case as both began to believe that Yuu was his younger brother. This continues through to the sequel, where he's the one who finally pesters them to get married, 13 years later.
  • Bishōnen: He's somehow both this and arguably the manliest of the Toryo High School students. His long hair is easily his most notable feature.
  • Brilliant, but Lazy: 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 The Prankster as always.
  • Chick Magnet: Although he only has eyes for Meiko.
  • The Gadfly: An even bigger one than Yuu is. He enjoys making fun of Miki, Yuu, and Meiko every once in a while.
  • Hopeless Suitor: To Meiko. Come on, Miwa. Why are you after one of the few girls who doesn't like you that way?
  • I Want My Beloved to Be Happy: Ultimately the reason why he finally forces himself to move on from Meiko. He indeed cares for her, but the fact that he can't really do anything to help her frustrates him, especially after finding out that she and Namura are getting married.
  • The Prankster: He likes pranking people.
  • Jerk with a Heart of Gold: Loves pranking and snarking at people, but is a loyal friend when his "victims" need it.
  • Mistaken for Gay: He was initially believed to be gay by Yuu after Satoshi takes an "interest" in him only because Satoshi believes that Yuu is his younger brother. After the two start to become closer, rumors begin to spread about both him and Yuu being gay, frustrating a jealous Miki. He uses Miki's fear to tease her and fuel her jealousy flames, but it backfires on him when even Meiko starts to believe he's gay.
  • Shipper on Deck: Yuu and Miki may find Satoshi's pranks and teasing annoying, but when it comes to their relationship, they may never find a better wingman, especially in the anime.
  • Student Council President: He is the student body president and a third-year student.
  • Tall, Dark, and Snarky: While his skin color's not dark, pretty pale in fact, he has the hair color, height, and the snarky personality.
  • What the Hell, Hero?: On Namura, about hiding his Hidden Heart of Gold. Namura takes it without retaliation... but too bad that Meiko got caught in the crossfire, much to his horror.

Voiced by: Kazunari Tanaka (JP), Skip Stellrecht note  (EN)

Leader of the broadcasting club.

  • Nerd Glasses
  • Nice Guy: Though very eccentric, especially when not in "journalist" action.
  • School Newspaper News Hound: Which brings Miki and Yuu a lot of trouble when he takes pics of Miki and Yuu's recently re-married parents, revealing them as swingers. To his credit, Furutachi immediately regrets the mess he inadvertently caused and alerts the parents when Miki and Yuu were harassed by a Sadist Teacher.
    • His future is to major in journalism and his dream career is to become an acclaimed news anchor. Though the others think he'd be better in a sitcom or a kid's show.


  • Moral Guardians: Threw quite a fit when she found out about the Matsuuras and the Koishikawas being swingers.
  • No Name Given: "Kyoto-sensei" is her title and position in the school itself. (She is the vice-principal.)
  • Sadist Teacher

Other students

     Arimi Suzuki 
Voiced by: Aya Hisakawa (JP), Carrie Savage (EN), Rosario Zamora (Latin-American Spanish), Pilar Domínguez (Spaniard Spanish)

  • Adaptation Dye-Job: Brown hair in the manga, green hair in the anime.
  • Amicable Exes: 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.
  • Childhood Friend Romance: The unlucky version with Yuu.
  • Clingy Jealous Girl: When it comes to Yuu.
  • Dude Magnet: She has many admirers at her school and even her own fan club.
  • Family Versus Career: 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 Poor Communication Kills, albeit one that lasts three years.
  • Friendly Enemy: Despite being Miki's love rival, the two girls actually get along quite well.
  • Girly Girl with a Tomboy Streak: She's a fashionable, graceful, and popular Dude Magnet, but has short hair and is the star of her school's track team.
  • Operation: Jealousy: With Ginta. And then, they fall for real.
  • Pair the Spares: Eventually hooks up with Ginta, and marries him in the sequel.
  • Passionate Sports Girl: Member of her school's track team.
  • Tsundere: Mostly deredere towards Ginta, but tends to get annoyed and jealous from time to time.
  • You Gotta Have Blue Hair: In the anime she has green hair.

     Tsutomu Rokutanda 
Voiced by: Kazunari Tanaka (JP), Tom Gibis (EN), Pablo Ausensi (Latin-American Spanish), Alfredo Martínez (Spaniard Spanish)

  • Butt-Monkey: Ties with Miki on the amount of slapstick he pours into the series. Not to mention his presence is usually met with the annoyance of his cousin and their friends, and the poor guy never had a chance with Arimi, often getting bullied by her fan club. Things eventually get better for him later in the anime.
  • Clashing Cousins: His usual relationship with Ginta, but every now and then they remind us that they are indeed family and will go to great lengths to support each other.
  • Dogged Nice Guy: To Arimi.
  • Hopeless Suitor: Again, he has always been this to Arimi, as far back as elementary school.
  • Hot-Blooded: Like his cousin (and perhaps even more so), he's the Slice of Life shojo version of this.
  • Large Ham: Loud, Hot-Blooded, and has No Indoor Voice.
  • Shipper on Deck: Once he stops being Arimi's Dogged Nice Guy, openly supports her and Ginta. In the anime, he goes as far as giving a What the Hell, Hero? speech to Miki when Ginta 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.
  • Small Name, Big Ego: He has a habit of making challenges to Ginta or Yuu or both of them together, forcing them to get buzz cuts if they lose. He's always the one to lose and the one who has to shave his head.
  • Stalker with a Crush: Towards Arimi, who initially rubs off the idea of him spying on her day and night, only for her and Ginta to swiftly realize that he probably would.
  • The Friend Nobody Likes: Greatly emphasized when he meets a majority of the main cast at the town's New Year's festival, only for all of them to sigh and moan once he shows up. Twice. By the time he ends up with Yayoi, this is toned down.
  • Throw the Dog a Bone: In the anime, he not only is more sympathetic and eventually 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"
  • You Gotta Have Blue Hair: In the anime he has indigo hair.

     Kei Tsuchiya 
Voiced by: Akira Ishida (JP), Ogie Banks note  (EN)

  • Belligerent Sexual Tension: Has a little with Suzu, in the anime.
  • Crazy Jealous Guy: Maybe the worst among Miki's suitors in regards to this.
  • Elegant Classical Musician: Plays the piano beautifully.
  • Just a Kid: He begins to see himself as this in comparison to Miki, of all people. He's very unhappy about that.
  • Kick the Dog: 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.
  • Pair the Spares: Has been dating Suzu by the sequel.
  • Peerless Love Interest: Sees Miki as this.
  • Stage Mom: Both of his parents were this. He ran away from home because of their pressure on him. They get better.
  • Stalker with a Crush: Rather possessive of Miki, as she's one of his very few friends, and he does some serious work towards isolating her from Yuu.
  • Took a Level in Kindness: In the anime, when he re-appears long after his arc is over, he's much more mature and kinder.

Voiced by: Hikaru Midorikawa (JP), Sam Riegel (EN)

  • Chick Magnet: Played for Laughs. The girls in his class swoon and chase after him. Unlike some of the other characters, he’s not too excited about that.
  • Crazy Jealous Guy: When it comes to Miki.
  • Forceful Kiss: On Miki, when she tells him "You're Just a Kid!"
  • Foreign Exchange Student: Hosted at Miki and Yuu's house.
  • Funny Foreigner: Downplayed, as he's introduced this way upon arriving to Japan, where most of his knowledge of the country comes from watching karate and feudal-era samurai movies.
  • Keet: He's cheerful, easily excitable and energetic, to the point where he's often compared to a little kid excited for Christmas.
  • New Transfer Student: An exchange student from New York.

     Brian Grant
Voiced by: Toshiyuki Morikawa (JP), Anthony Robert (EN)

  • Kendo Team Captain: Of the Basketball Team.
  • Boisterous Bruiser
  • Butt-Monkey: Slightly, as he comes off as more oblivious and childish than his other friends.
  • Chick Magnet: Like his little brother, he's got all the attention of every girl that knows him except for Jinny.
  • Crazy Jealous Guy: Though not as bad as Michael, and he gets over it quickly.
  • Drama Queen: A male example.
  • The Driver: Is pretty good behind a car's steering wheel, and he would be the default person to drive everyone around.
  • Drunk on Milk: Tends to do it all the time, even Bill lampshades this.
    Bill (to Brian, whose getting all dramatic while eating lunch): "Dude, this was soda right? You sure you didn't bought beer by mistake?"
  • Dumb Jock: When it comes to love and social relations, he really . lacks . tact. Brian doesn't get Jinny's clear and constant signal of "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, being oblivious to Doris' attraction towards himself, and not knowing that he's the Unwitting Pawn of Bill.
  • Fiery Redhead
  • Fun T-Shirt: A hoodie with "FORCE," a jacket with "Star," and a tee with "CON."
  • Hot-Blooded
  • Jerk Jock: 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 Shock Jock level.
  • Lovable Jock: Once you gain his respect and join his inner circle of friends, you'll see his air-headed silly side more often than not.
  • Oblivious to Love: Poor Doris...
  • Sensitive Guy and Manly Man: On the appearance, he's the manly man to Bill's sensitive man. But don't let that fool you, they are inverts. note 
  • Unwitting Pawn: Of Bill. 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, Bill leaves Jinny a way better impression than Brian. Had Bill be more aggressive, Brian can easily be psychologically crushed by him.

  • Badass Driver: More pro than Brian, and he would gladly level up to Drives Like Crazy when needed.
  • Big Brother Mentor: To Yuu, Jinny, and most likely the childish Grant Brothers.
  • Curtains Match the Window: And in Lavender!
  • Camp Straight: Most people in his school believes he's gay. Among his circle of friends, only Yuu, Anju, and Doris 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 air-head than to be a person who knows what's going on.
  • Dandere: He has a quiet, observant, and effeminate persona but with a very athletic, masculine, and hotblooded inner core.
  • Death Glare: Gave Jinny a loooong one to take warning, and yet she's stupid enough to despise it.
  • Doing Research: Whenever he's free for the night, he would usually stay in his dorm attic to study the stars using his telescope.
  • Gay Guy Seeks Popular Jock: What people around him rumored his relationship with Brian was. But this was only the tip of the iceberg of him being actually a Guile Hero. See trope below.

  • Be a Whore to Get Your Man: Attempted with Yuu and failed. Also used this reasoning to blame Miki for it when she lied about Yuu sleeping with her.
  • Book Dumb: 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.
  • Clingy Jealous Girl: When it comes to Yuu.
  • Dumb Blonde: More like "selfish and childish blonde" than truly dumb.
  • The Fashionista: According to 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.
  • Green-Eyed Epiphany: Towards Bill. Upon noticing him not being gay and enjoying his alone time with Anju, she started to panic over her attraction to Bill, and took the step forward in confronting him, which eventually led to Bill becoming her boyfriend.
  • Informed Attractiveness: This being anime, she objectively looks no prettier than Miki note , and while she clearly isn't drawn with the same care as Meiko or Arimi are drawn with, the viewer is left to believe the narration's insistence that she is Hotterand Sexier than other girls. This could be mostly blamed on the Anime's wonky character design.
  • Kick the Dog: 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 Long-Distance Relationship.
  • Light Feminine and Dark Feminine. Dark to Doris' Light.
  • Lovable Alpha Bitch: Jinny's not an all-around bad girl to people, just a mischievous pampered girl who crossed the moral line once. Doris and Bill are certainly the two unsung heroes who can truly ground her.
  • Love at First Sight: Towards Yuu, she probably had a thing for nerdy East Asians.
  • My God, What Have I Done?: After Bill and Doris express their anger at her for her treatment of Miki.

     Eddie and Chris 

Marmalade Boy Little

     Rikka Matsuura 
Yuu's and Miki's little half-sister. Stepsibling to Saku.
  • Almost Kiss: 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.
  • Big Brother Attraction: 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.
  • Book Dumb: 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?
  • Clingy Jealous Girl: 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...
  • Flirty Stepsiblings: It wouldn't be Marmalade Boy if they weren't. Complicated by them actually being raised as siblings from birth, even though they are Not Blood Siblings.
  • Generation Xerox: Basically, Miki all over again, right down to the habit of Suddenly SHOUTING!! when startled; keeps her hair a bit longer, though.
  • Headbutt of Love: With Saku
  • I Didn't Mean to Turn You On: Happened more than once towards Saku. The last time it happened Rikka is 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....
  • Like Brother and Sister: Averted. As Saku hits his growth spurt, Rikka really begins to notice how good-looking he is.
  • Oblivious to Love: Saku isn't exactly quiet about how he feels about Rikka, but it takes her through junior high school to finally notice.
  • Shipper on Deck: For Emiri and Koudai
  • When She Smiles: Saku confesses that he loves Rikka's smile very much and wishes she would always smile like that.

     Saku Koishikawa 
Yuu's and Miki's little half-brother. Stepsibling to Rikka.
  • Anger Born of Worry: 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.
  • Chick Magnet: Duh.
  • Childhood Friend Romance: Multiply this by lifelong stepsibling. Eep.
  • Crazy Jealous Guy: Downplayed and Discussed. Saku is pretty chill while Rikka and Aoi are dating. However, after Aoi and Rikka break up, Saku admits that although 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!
  • Flirty Stepsiblings: Effectively Single-Target Sexuality: he is and has always been in love with Rikka, especially since he's well aware they are Not Blood Siblings.
  • Generation Xerox: As brooding as Yuu, and just as fixated on his stepsister (Rikka in this case).
  • I Want My Beloved to Be Happy: 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.
  • Headbutt of Love: Initiates this with Rikka
  • Like Brother and Sister: Averted.
  • Spell My Name with an "S": Early fansubs translated his first name as Hajime, due to the ambiguous nature of kanji readings.

     Aoi Namura 
Handsome transfer student from Hiroshima.
  • Chick Magnet: Given who his parents are, would you expect any less?
  • Late-Arrival Spoiler: His very existence spoils that Meiko and Namura-sensei end up married.


How well does it match the trope?
