The Protagonist of the series. A transfer student to Ouran High School who winds up working with the Host Club to help pay off her debt after accidentally breaking a really expensive vase.
A-Cup Angst: The subject rarely comes up, but she doesn't seem too happy with her bust. She gets mad when a swimsuit is picked for her that hides a flat chest and after she realizes she likes Tamaki she laments her boyish face and figure.
Allergic to Love: After she realizes she is in love with Tamaki. She gets better later.
Ambiguously Bi: States that she doesn't care about genders and blushes in the anime when she accidentally kisses Kanako, which would imply that she's open to fall for girls. Her being Oblivious to Love however keeps this from being further explored.
Animal Motifs: Often compared to a raccoon for her cute face and homely nature.
In the anime, when helping the Zuka club with their play. There was no emoting involved whatsoever.
Averted when dealing with the club's customers, but it's made fairly clear that she doesn't think of it as playing any kind of role. When she's a host, she's mostly just being herself; the guys identify her immediately as the "natural type".
Bokukko: Uses "boku" and occasionally "ore" to refer to herself.
Catch Phrase: Something along the lines of "I hate these damn rich people."
Character Development: She goes through a lot, from disliking the Host Club and not having an once of curiosity for anything in the world, to slowly warming up to them and participating more and more in the activities until she ends up loving them and even stays with them after her debt is paid. Through this she grows more outgoing and determined, and also learns to appreciate Tamaki, seeing him for the immensely kind person he is until she falls for him. Even with this revelation she goes through quite a bit; she initially freaks out and tries her best to deny it, until she eventually calms down, but decides that she still "has so much to learn" before she can tell him, and hides her feelings for a while, returning more or less to her old self. Being more and more confronted with her feelings however, through sharing an Accidental Kiss with him and actively helping him get reunited with his mother, she ultimately can't keep it in anymore and confesses to him. After two years of dating, the two happily gets married.
Clueless Chick Magnet: She used to get confessions at least once a month, usually more. However, when people like Arai or Hikaru confess to her, she assumes they mean something like 'I want to go to Ouran as well' or 'want to go outside with me?'
Defrosting Ice Queen: Haruhi may not have been a full-blown Ice Queen, but she initially cared little for the Host Club and solely cared about fulfilling her debt until she gradually befriended all the Host Club members and grew to love the Host Club.
Dude Magnet: As a girl, she got confessions regularly. As a 'boy' she gets as many or more fangirls than anyone in the host club short of Tamaki.
Friend to Bugs: Implied in Episode 8 when she finds a centipede on a crab and, instead of killing it, she simply picks it up and throws it aside. When asked if she could have been easier on it, she said, "It takes a lot more than that to kill a bug."
Gender-Blender Name: Haruhi is a valid boy's name and since she's working class nobody knows about her family or history. Thus, she can use it to her advantage and pretend to be a guy, though it wasn't her original intention.
Generation Xerox: Looks and acts a lot like her deceased mother. Like said mother, she becomes a lawyer and falls in love with and marries an idiotic Nice Guy.
The Glasses Gotta Go: When Tamaki first removes Haruhi's glasses, revealing her large, bishonen-style eyes. The host club insists she wear contacts from then on, as her eyes are apparently a draw for female customers.
Green-Eyed Monster: Reveals to have felt this way towards Kanoya, a transfer student who crushed over Tamaki and continuously sticked by his side after he saved her from getting kicked by a horse.
Hime Cut: Before she cut her hair short. A inversion as she lacks every single trait normally associated with it.
I Can't Dance: In the ball before she goes to America Haruhi ends up stepping on Tamaki's feet when they dance since it's her first time dancing the girl's part.
I Choose to Stay: Remains with the Host Club after her debt is paid (in both anime and manga).
Imagine Spot: Subverted. That distant, unfocused look? It means she's mentally reviewing this week's store specials as she plans her grocery shopping list.
Informed Attractiveness: Most of the Host Club members and especially Tamaki will continuously fawn over how "cute!!!" she is, even though they're surrounded by equally, if not more, cute girls on a daily basis. The same goes for the Zuka club, and in the past, Haruhi had apparently received love confessions from guys once a month. Though it might be her boyish and "natural" look that makes her stand out.
Innocently Insensitive: While she can be intentionally rude, most of the jerky statements she makes are said without any malice. Coupled with her emotional density and popularity you have a social disaster waiting to happen.
Inter-Class Romance: With Tamaki; he's ultra rich and she's a working class girl with middle class aspirations.
Invisible Subtle Difference: The only one who can note the subtle differences between the twins is Haruhi, implying that she judges people more by inner character than surface appearance.
The Kirk: More levelheaded than most of the club members, able to judge situations and respond accordingly. She rounds out Tamaki's passion and Kyouya's shrewdness.
Lady Looks Like a Dude: Very early on, Haruhi is assumed to be male because of her very unflattering appearance.
Like Parent, Like Spouse: It's constantly lampshaded how similar Tamaki is to her father (minus the fact that her father is a bisexual professional crossdresser). They get married at the end of the final bonus chapter.
Mistaken for Gay: Before Haruhi goes to America, the Host Club arrange a ball in honor of her decision, and eventually have her show up with a wig and dress to show their customers that she's really a girl, a revelation they happily accept, admitting they knew already. However as it turns out, they thought she was just fond of cross-dressing, and that they were supporting a "forbidden love" between her and Tamaki.
Penny Among Diamonds: A commoner who manages to make it into an elite private school for the very rich.
Precision F-Strike: Played for Laughs; she occasionally refers to herself as "ore", which isn't necessarily as bad as the F-word would be in the English language, but Tamaki treats it as such and the word is almost always bleeped out when she uses it.
Protectorate: Mess with her and the whole Host Club will be after your blood.
She Cleans Up Nicely: It's just that cleaning up is such a drag for her because of all of the time she has to spend on housekeeping. If it were up to her, she would be going around school in her infamous Haruhi Potter wear every day.
Single-Target Sexuality: Does not show an ounce of interest in any guy or even romance in general before she falls for Tamaki.
Sloth: Apart from being something of a jerk occasionally, this is her main flaw. Though she's certainly not lazy at school or at home, she never wants to do anything new or even slightly troublesome. Justified in that she doesn't want anything to distract her from achieving her goals.
Supporting Protagonist: She's the view point character but she's dragged along by debt into the host club activities.
Tomboyish Name: She is mistaken by most people to be male partially because "Haruhi" is an unisex name.
Tomboy with a Girly Streak: She dresses like a boy at school and doesn't care if people mistake her for one. While she doesn't mind dressing up in feminine clothing when the occasion calls for it, her everyday clothes are obviously chosen primarily for practicality. On the girly side she has a severe Fear of Thunder and her hobbies include cooking, cleaning and sewing. The anime gave her a distinctive dress over jeans weekend outfit to underline the two sides of her character.
Unwanted Harem: Tamaki, Hikaru, Kaoru (shown more so in the manga), Renge, Kasanoda, and her middle school classmate Arai all like Haruhi. She was even confessed to by her old schoolmates an average of once per month prior to transferring to Ouran. Not that Haruhi noticed any of that.
Wholesome Crossdresser: Played straight with Haruhi herself, but zig-zagged with the club guests/fangirls. At first, they invoke this trope when they remark that they'd love to see how Haruhi would look dressed as a woman, and later, when they claim to have figured out Haruhi's "secret", they agree that "he" DOES look good as a woman. It's not until later that they realize that Haruhi is, in fact, female, and that the "closeted gay boy" they've been championing this whole time was not.
Women Are Wiser: She seems like this as she is much more sensible then her clubmates, but it's more like 'commoners are wiser' as the club's customers are just as silly as they are. Both live in awe of "commoner wisdom."
The founder and president of the Host Club and quite the charmer (even though he comes off as a well-meaning idiot half the time). Tamaki likes to think of himself as the "daddy" of the Host Club, and thinks of Haruhi as his "daughter".
All-Loving Hero: This guy will help anybody, anytime. It is explicitly this which brought the host club together in the first place, and it makes the other club members highly loyal to and protective of him.
Animal Motifs: A dog, for his energized, lovable and loyal personality.
Anger Born of Worry: He yells at Haruhi for trying to take on a group of bullies by herself and nearly getting killed in the process.
Beware The Nice/Silly Ones: It's pretty scary to see him angry. He will snap at anyone who puts Haruhi's life in danger (including Haruhi herself), and in general; don't mess with any of his Host Club members or their guests. You will be sorry.
Camp Straight: He's effeminate, carries roses everywhere, volunteered to wear a pimped out dress and yet he only has eyes for Haruhi.
Character Development: He eventually realizes his feelings for Haruhi and also learns that the Host Club bonds are so strong that they won't break apart even if he should pursue her. Later Haruhi teaches him to quit hiding his feelings (when he pretends he doesn't want to see his mother) and that it's much better for a family if he, his father and his grandmother would just be honest with each other.
The Charmer: He has his dad's talent at sweet-talking people.
Chick Magnet: He's the Club's king for a reason; 70 percent of the club's customers chose him.
Crazy Jealous Guy: Can sometimes fall into this in regards to Haruhi. He's mostly harmless and a lovable idiot though.
Crouching Moron, Hidden Badass: He can shift from "simpering fop" to "forceful leader" instantly if the situation is sufficiently serious. He's also more athletic than one would think, and he can pull off a damn good Dynamic Entry.
Determinator: Perhaps the flakiest and flightiest character to ever earn the distinction, but Tamaki resolutely refuses to be forced to choose between any of the people he cares about. Which comes to a big shock to his father when Tamaki makes it quite clear he wants good relationships with both his mom and his Evil Matriarch grandmother, and puts him in agony when his grandmother forbids him from having any contact with Haruhi.
Deuteragonist The main plot of the show and its action is caused by him.
Drama King: He zig-zags this trope as shallow or immediate issues at hand will greatly upset him, making sure everyone else sees his problems as well. When it comes to real, psychological issues regarding himself or his family however, he will keep it hidden and pretend like, or convince himself that everything's fine.
Dumb Blond: He acts like a ditz, but he effortlessly gets the second best grades in the second year classes behind only Kyoya.
Most of Episode 23's plot, Tamaki's Unwitting Depression, revolves him lamenting about Kasanoda knows that Haruhi is a girl, and realizing that he's not Haruhi's father. Of course, it's played for laughs.. To an extent.
In Episode 25, Eclair More Than Mind Controls him into shutting down the host club, which is aided by the notion that he and that the host club are becoming burdens to the others. His presence has diminished like a snuffed out candle.
The McCoy: The most passionately driven member of the club, quick to let his emotions guide him and throw him into all kinds of trouble.
Meaningful Name: In Chapter 77, he points this out to his grandmother, that his father had chosen his name which means "a circle overcoming everything" or more spesifically "ring", no doubt complimenting his personality.
Missing Mom: Tamaki's Evil Matriarch grandmother sent her to the French countryside and forbade any kind of contact between them.
Mistaken for Gay: His clients realize that he and Haruhi are together and are accepting of it, thinking that Haruhi is a guy and that they're having a "forbidden relationship" with each other.
Taking the Bullet: In a downplayed version of the trope: he saves a transfer student from getting kicked by a horse, shielding her with his body which ends with him getting kicked instead. He's not badly injured however, but still has a hurting shoulder for a while afterwards.
The vice-president of the Host Club, and one of Tamaki's closest friends. Kyouya tends to take a more responsible approach to the club's activities, and tries to make sure that Tamaki and the others don't go overboard.
Miser Advisor: Of a more proactive variety; he's the only reason the club still has money.
Not a Morning Person: It's very hard to wake him up. In one of his day-in-the-limelight episodes, Tamaki and the rest of the Host Club descend upon Kyouya in the morning, stuff him into his clothes, and drag him all the way out to a shopping mall before he finally comes around into consciousness.
Not So Stoic: Episode 24 of the anime; in the manga, his blow up at Tamaki's father.
Poisonous Friend: A relatively mild example given the idealistic tone of the series, but definitely in effect between Kyouya and Tamaki. Tamaki, All-Loving Hero, wants to help everyone and seems oblivious to any signs that anyone might have it out for him; Kyouya is entirely okay with going behind Tamaki's back to protect his interests and make it very clear that anyone who messes with him will be made to regret it. The newspaper club episode provides a particularly vivid example.
The Proud Elite: He is the brain behind the Host Club. He acts as though he cares only about the bottom line and what will benefit himself, as he feels befits the third son of the Ootori family, but he has been shown to have a well-hidden altruistic streak.
Raven Hair, Ivory Skin: The visual and his demeanor make him a colder beauty for customers than Tamaki's golden charm.
Team Mom: According to Tamaki, but he's really the stern and disciplining Team Dad.
Token Evil Teammate: Kyouya is considered by everyone in the club to be more or less evil, especially compared to everyone else. Even the twins are afraid of him, but he's still mostly a good guy.
Tsurime Eyes: Another visual contrast with Tamaki; there's nothing soft about him.
Unkempt Beauty: As shown in Episode 17, Kyouya still looks good even when he's literally dragged out of bed in frumpy clothes and bed hair.
"Well Done, Son!" Guy: As the third son to his family's line of work, he's pressured himself to surpass his older brothers' considerable achievements in order to have any chance of impressing his father and earning the right to inherit leadership of their company. It's when Tamaki enters his life that he starts to loosen up and care for other people for something other than business benefits.
In the anime this ultimately leads to a Crowning Moment of Awesome in which he buys his dad's company (or at least the majority stock) from a competitor who was blackmailing his dad with it. Then he gives the whole thing right back to his dad like it's nothing at all.
Expy: They're like flirtier, more sociopathic versions of Fred and George, though it's probably a coincidence.
Fake Defector: After Kaoru's made both of their feelings for Haruhi clear, he yells at Hikaru for still being too naive and he'll never let him have Haruhi if he'd really be okay with sharing her. The following days he then proceeds to flirt with Haruhi in front of Hikaru, telling Haruhi not to bother with him, asking her on a date and so forth. It then turns out he was intentionally trying to make Hikaru hate him so that Hikaru would "break free" from him, feeling he was in the way for his happiness for the way they were so codependent on each other. Luckily however, Hikaru sees through this and eventually convinces Kaoru he's wrong, and they will still always be together even if they start embracing their differences more, and for the sake of being distinguished, simply dying their hair will be enough.
Fiery Redhead: Hikaru is, but Kaoru is better at keeping his feelings in control. Defied later on when Hikaru dyes his hair a darker shade.
Green-Eyed Epiphany: Hikaru had been developing feelings for Haruhi for quite some time but kept mum about them. However, when an old school mate who was in love with Haruhi, Arai shows up and spends some time with her, Hikaru immediately becomes very possessive of Haruhi, making his feelings much more conspicuous.
In the manga, Haruhi at some point talks very fondly of Tamaki to the point Hikaru gets pissed off and walks away, followed by Kaoru. Still being oblivious to why he feels like that however, Kaoru tells him how it's because he's in love with Haruhi.
I Love You Because I Can't Control You: Invoked. Haruhi is the only one who isn't phased by their antics and who they can't seem to fool by a Twin Switch. This is what piqued their interest in the first place and the more Haruhi can tell them apart and shrugs off their pranks, the more they want her to themselves. Being in the same class only increases the effect in the matter.
Ineffectual Loners: Up until they joined the Host Club they scorned the company of others.
Jerks With Hearts Of Gold: They can be downright harsh at times, particulary in the flashbacks, stemmming from their past self-isolation and condescending outlook on other people who couldn't tell them apart (which is why Haruhi interests them so much). However, they've had plenty of Pet the Dog moments to counter this, especially Hikaru.
Not So Different: From Tamaki. Especially in their backstory, where they dismiss Tamaki as an idiot, but whenever there's a bit of Tamaki goofiness going on, chances are, the twins are right behind. Sure, maybe it's For the Lulz, but deep down, they can be just as silly as he is. Likely due to Tamaki being the first person to break them out of their insular shells.
Red Oni, Blue Oni: Hikaru starts a lot of trouble and is impulsive if separated from Kaoru, while Kaoru is the colder brother and is usually more calm and collected if separated from Hikaru.
Shared Family Quirks: Their love of playing with people's minds (as well as a taste in fashion and make-up) comes from their mother and maternal grandmother. Their little sister in the bonus chapters is exactly the same as them when they were her age.
Sibling Triangle: Hikaru and Kaoru both develop feelings for Haruhi. Kaoru gives up on Haruhi because he cares about Hikaru more than his feelings for Haruhi and steps down, instead rooting for Hikaru to win Haruhi. However, after realizing Haruhi's and Tamaki's growing feelings for each other, Hikaru eventually decides to step down as well.
Significant Birth Date: They were born on June 9 (6/9), showing that they're alike, but different. It's even more significant when you realize people born on that day are Gemini.
Tsundere: Hikaru is a male example towards Haruhi. He's a rather brusque and proud but when he's alone with Haruhi, he's usually much more considerate, even tender sometimes.
Tsurime Eyes: Clues in on their devious, witty, and (mostly in Hikaru's case) prideful nature.
Twincest: The boys play up their "brotherly affection" for their clients. It's ambiguous as to how much of it is an act.
Twin Switch: Haruhi is the only person who can tell who is who, even when they are extra cunning. It was later revealed that their mother had long since developed the ability to differentiate them, but pretended to be clueless for the fun of it.
What Is This Feeling?: Hikaru starts getting upset and jealous regarding Haruhi without knowing why as the story goes on. It's not until Kaoru points out the obvious that he realizes he loves her.
Be Yourself: What Tamaki taught him during Hani's time of self-denial before joining the Host Club.
Big Brother Instinct: He loves his little brother dearly, but the feeling isn't mutual. He also cares deeply about his fellow Host Club members. They serve as a Berserk Button if any of them are threatened.
Big Brother Mentor: In the manga though even there his relationship with his brother Chika is a little wacky. In later chapters he occasionally plays this role for Kaoru.
Big Eater: He eats three whole cakes every night for dessert.
Bunnies for Cuteness: Hani has a rabbit motiff to help establish him as the cute character of the Host Club. He carries around a pink stuffed bunny with him almost all the time. He can also make bunny shuriken, has a martial arts move called a "bunny kick", and in the manga a bunny-patterned background is sometimes used for panels featuring him.
Creepy Child: How his brother thought of him; it was like Nekozawa.
Cutesy Dwarf: Likely the cause of his shota appeal. It is revealed in an extra one-shot that Kyouya had been giving him vitamins in order to stunt his growth, as they already had a "Dumb blond character" (Tamaki) and didn't need another one. Once he stopped getting the vitamins he grew 32 centimeters in two months. It's a dream Haruhi had, but still.
Hair of Gold, Heart of Gold: As proven by Renge, he has no 'angst side'. He really is that cute and sweet; inside and out. When told to bully Haruhi for a movie, he can't keep up the act and breaks down crying and apologizing.
Remember the bunny shaped mushroom cloud of explosion!
His father forbid him from ever fighting at full strength. If he did, other countries might think that Japan was making a WMD.
Real Men Wear Pink: Before he met Tamaki he was convinced to act like a manly man but then he joined the club and carried around Usa-chan. His father said he'd only allow him to go back to his cutesy ways if he beat him in a duel. Honey sent him to the hospital, covered in casts and bandages.
Red Oni, Blue Oni: Red, red, red. What's with these pairs and their conflicting personalities?
To Haruhi, almost from the very first time they meet - in the first episode of the anime, she calls out to him for help and he runs to her aid without a second thought.
This could easily go with Mori's real little brother.
Big Brother Mentor: To Honey again. While normally very supportive, he's the one to tell Honey when he can't do something, and is the only one who can really stop him. In the manga, he occasionally acts as one to Hikaru as well.
Gentle Giant: Tamaki explains that this is his biggest charm: he looks intimidating but cute adoring Honey is a visual cue that he's friendly and gentle. It's also explained that Mori's fans among the host club's patrons tend to be shy, quiet girls who find his quiet, steady stoicism reassuring.
Hunk: Compared to the other Host Club members, he's incredibly tall and muscular, making him the most distinctly masculine of the group.
Legacy of Service: Mori comes from a family with a long line of serving the Haninozuka clan. The master-servant bond was dispelled when the families were joined by marriage, but Mori still watches over and protects Honey like a big brother would.
Master Swordsman: Though never seen, he is a kendo champion, and on occasion swings a sword around.
The Quiet One: Mori does occasionally speak, but it's usually in short sentences. When he is very tired he becomes flirtatious and chatty. Weird.
Rated M for Manly: He's really tall, really strong, great at martial arts and has a deep booming voice (in the rare events that he talks). To drive the point home, he was the only member of the Host Club who didn't crossdress during the whole Zuka Club fiasco.
An occasional visitor and self-proclaimed "advisor" to the Host Club. She used to live in France for a time before coming to Ouran at her father's behest. She has a one-sided infatuation with Kyouya, due to his resemblance to a character in one of her favorite dating sims.
Affectionate Parody: Of the fandom; a Nice Girl who likes dating games/harem anime and yaoi pairings. The difference is the cranked up energy and the High-Powered-Motor.
Genre Savvy: She starts out as Wrong Genre Savvy, but becomes this after joining up as the Host Club's "manager". Being a fangirl herself, she knows what fangirls want and, when Tamaki and Kyoya run out of ideas, she usually comes up with some for them. However, this largely applies to the anime as a lot of her roles in the manga were given to Tamaki.
Nekozawa (almost always referred to by his family name) is the president of the Black Magic Club, identifiable by his black cloak and Beelzenef hand puppet. Despite his creepy demeanor, he's actually a nice (and incredibly cute) guy under the hood.
Perky Goth: After patching up his relationship with his sister he becomes less sour and more happy.
Sibling Yin-Yang: He's the president of dark arts club, wears black, hates going out in the light, and has a cat-like puppet while Kirimi hates everything related to darkness, wears bright clothing, and bursts into tears if she's within close proximity of a cat.
Bi the Way: If labelled as 'gay', he will be quick to explains that he swings both ways, although he adds that he could never love another woman after Haruhi's mother.
But Not Too Bi: While he's never actually seen romancing another man, he did say that the only reason he let the Host Club follow him while he tailed Haruhi at the super market was because he "wants to be seen around a bunch of cute boys" and told Tamaki that he won't win him over just because he's handsome.
Children Raise You: Because of Kotoko's death and his long work hours, Haruhi does most of the work at home; cleaning and cooking for Ryoji and otherwise trying to take care of him, even telling him not to overwork himself for her.
Mistaken for Gay: Variation. Ryouji IS genuinely attracted to men, and he would rattle off so often about guys he liked to her that Kotoko couldn't understand why he kept inviting her to have meals with him. Ryouji was a bit disgruntled to learn that the idea he was bi and actively trying to pursue a relationship with her hadn't crossed her mind.
Haruhi's late mother. She was a lawyer, and it's from her Haruhi inherited most of her personality.
Always Someone Better: She was this to Yuko Kosaka, a lawyer student who envied her skills and also the fact that she married Ryouji, whom Yuko had a crush on.
Characterization Marches On: Early flashbacks shows her as a mature, level headed woman who nearly always smiled and openly showed affection. In the extra, it turns out she (at least was) a bit of a Tsundere, and it took some work from Ryouji to make her smile at him.
Fourth Date Marriage: Towards the end of the extra she narrates how she surprised her coworkers with marrying a man she'd only known for two months, next to him being six years younger than her. Despite all that they still ended up Happily Married.
Kasanoda is the successor to one of the most powerful yakuza groups in Japan. He is one of the first members outside of the Host Club to learn of Haruhi's secret. She calls him "Casanova", while the twins jokingly refer to him as "Bossa Nova".
Be Careful What You Wish For: He wanted to be liked, not feared. By the end, he befriends his underlings, has become liked in school, and popular with girls. Everyone thinks he's gay now, but whatever.
An anime-only character. She's a young girl from France who is in love with Tamaki and ropes him into an Arranged Marriage with an offer he really can't refuse... the chance to see his Missing Mom again.
Arranged Marriage: With Tamaki. Unusally for the trope, she is all for it and even had a hand in it.
Rich Bitch: At first. She is a rich girl who waltzes in and demands Tamamki. Then she shows a different side.
Well-Intentioned Extremist: Eclair coerces Tamaki into marrying her, causes the dissolution of the host club, and conspires with Kyouya's Jerkass father. It's all a plan to get Tamaki back with his Missing Mom, with whom she's friends.
A manga only character, Mei is the daughter of Ranka's co-worker and friend Misuzu, and is one of the first non Host Club members to realize Haruhi's feelings for Tamaki. She admires the twins' mother and enjoys designing fashions. She is Haruhi's only female friend.
Benio (or "Benibara", as she's known to her peers) is a student from the all-female St. Lobelia academy. She believes that all females are meant to be pure, and dislikes the flirtatious nature of the men of the Ouran host club.
Large Ham: Another similary she shares with Tamaki.
Nice Girl: At the end of Chapter 31, she reveals that she merely wanted to borrow Haruhi for the sole purpose of helping out with walking Zuka Club newbies through playing boys onstage, and makes up for the trouble she might've caused the Host Club in the process by inviting EVERYONE in the Host Club (Haruhi included) to the latest Zuka Club production.
The Rival: To Tamaki, too. It's usually over Haruhi's attention.
Chika is Honey's younger brother. Like Honey, he is an expert martial artist, and is also the captain of the judo and karate clubs. He takes his work very seriously, and is disappointed that Honey doesn't.
Tamaki's father, the Chairman of the School Board over Ouran Academy as well as the head in charge for the Suoh company. He had Tamaki through an affair with a French woman while on a business trip, a woman he later tried to marry. However, his mother refused, and had them separated.
Beware the Nice Ones: He's caring, polite and charming and has an incredibly touching love for his son. At the same time he can also be a very serious, even cold business man. At one point he fires his mother behind her back after months, possibly even years of careful planning towards that opportunity.
Bumbling Dad: He becomes this when in a good mood, which is usually whenever he's around Tamaki.
The Chessmaster: Turns out his and Kyouya's father's companies had worked together on finding a cure for Anne Sophie's illness without anyone knowing, to which he meanwhile had pretended to abide by his mother's rules and not making any effort for Tamaki to see his mother even though he seemingly should have had the power to. Once a cure is apparently successfully made, he gathers his companies' directors and has Shizue fired, while attempting to tell Tamaki the "good news". Tamaki is everything but pleased.
Doting Parent: For being a business man of high social standards, he has no issues openly fawning over Tamaki through hugs, hair ruffling and affectionate words. What's funny is this makes Tamaki about as embarrassed or annoyed as he usually makes Haruhi.
Honest Corporate Executive: He can be cold and cunning but he's ultimately on the level. Like the Host Club, the Suoh Company has a benevolent king.
My God, What Have I Done?: He goes through this when wondering if Tamaki hates him for what he did against his grandmother, and acknowledges that he went too far, when he ponders to initially only have wanted to prove himself for her, who had always controlled and been at the top of everything. After Tamaki's reunited with his mother, the two are also shown reconciling, deciding to have a talk "not as president and subordinate, but as mother and son".
Not So Stoic: His apparent aloof personality drops in a instant when he suddenly flirts with Haruhi out of nowhere, sporting a goofy grin and asking her to call him "uncle". In the manga, his introduction is through scolding Tamaki, until it turns out he was joking, and pokes at Tamaki's embarrassed face while commenting how "cute and stupid" his son is.
Haruhi:He's Tamaki-senpai's father alright...
Starcrossed Lovers: With Anne Sophie because of a wealth gap and the fact that he was engaged at the time. Averted at the end.
The Stoic: Averted. He's essentially introduced as this in both anime and manga, and even Haruhi thinks how he doesn't remind her of Tamaki at all. Then he reveals that he was joking.
Your Cheating Heart: At one point he reveals how his arranged fiancee was having an affair, something he knew about but pretended not to, due to his lack of feelings for her as well. He then fell in love while on a business trip to France and had an affair himself, resulting in Tamaki.
Anne Sophie de Grantaine
Tamaki's mother, whom he lived with in France until he was 14. After letting Tamaki go to Japan and being forbidden from ever seeing her son again, she was rumored to have gone into hiding. Eventually she appears in the manga, being found by Kyouya secretly looking for her while on a school trip to France.
Anime Accent Absence: Speaks fluent Japanese despite being French, though unlike Tamaki, she does add some French words or sentences into her vocabulary.
The Faceless: In the anime, as well as for a while in the manga. Pictures and flashbacks of her are shown, but her face is always covered. It's not until Kyouya finds her that the readers finally gets to see what she looks like.
Ill Woman: Her fragile, ill body as well as her family's financial issues is what kept her from coming to Japan, and it's what Suoh Shizue took advantage of in order to blackmail her into exchanging her son for money.
It Runs in the Family: Tamakis' blonde hair and beauty as well as love for Japanese culture (especially kotatsu!) and fast recoveries from distressed emotions apparently all came from her.
Missing Mom: Quite literally throughout a good portion of the manga; until she is introduced it's simply stated that no one knows where she is.
The Mistress: She and Yuzuru fell in love when he was married to someone else. It's why Tamaki's position in the Souh family is precarious.
Tamaki's Evil Matriarch grandmother who offered to pay for his mother's financial issues in return for letting him come to Japan and being forbidden from ever seeing her again. Despite this trade, she doesn't accept Tamaki as an heir and refers to him as "filthy" for being the child of a mistress. She becomes better in the manga however, being revealed to have obtained a mask, and is a kind person underneath, something Tamaki eventually discovers as he gets the chance to be close to and befriend her.
In the anime, she arranges for Tamaki to be engaged to Eclair Tonnerre.
In both anime and manga, she arranged a marriage for Yuzuru, a marriage he left when he fell in love with a French woman on a business trip.
Beneath the Mask: Turns out she was never really evil, but wanted to "keep up appearances" in order to maintain her business that her late husband left behind from people who wanted to take it, which ultimately led to her cold demeanor.
Big Bad: In both versions, she is the primary antagonist and posses the greatest threat to the Host Club. In the anime, she's the one behind Eclair's attempts to marry Tamaki and take him way to France. In the manga, she makes a demand that leads to Tamaki leaving the Host Club. She eventually defrosts.
Break Up Demand: Upon letting Tamaki move in to the main mansion where she lives and having him study to work at her company (while she still hasn't accepted him as an heir), she demands that he cut his ties with Haruhi, pointing out what an offensive notion it is to have a student, particularly a transferred one, deceive the entire school by pretending to be a guy, and that Tamaki’s club being the reason for it puts the Suoh name in a bad light. As a result, Tamaki also quits the Host Club to further follow her ideology, however, it later turns out that while he indeed thought he had been irresponsible towards Haruhi, he also wants to find a way to show his grandmother that having relationships with people of different social statuses (his friends and servants as well as Haruhi) isn't a weakness.
Epiphany Therapy: Tamaki gives her one as he reveals to her how his father is the one who had taught him about all the things she herself loved, when she had thought he'd never cared for them. It's what coaxes her to realize Yuzuru still loves and cares for her.
Defrosting Ice Queen: Courtesy of Tamaki playing the piano outside her room for many days, including one that has special meaning to her.
Et Tu, Brute?: Her reaction to her son taking over her company and firing her behind her back leads to her secluding herself inside her room for days, with Tamaki the only one feeling sorry for her.
It Runs in the Family: Getting his mother and father's traits out of the way, turns out Tamaki's love for Japanese movies and dramas as well as miscellanious soundtracks from those works came from his grandmother. It's through this (Tamaki playing the piano everyday while she's secluded herself) that she eventually comes out from her room, when he coincidentally plays a piece from a movie she and her late husband used to watch often.
Karma Houdini: In the anime only. In the manga she is outgambitted, fired, and made to reconcile with her family.
Villainous BSOD: Played with. It's initially this when she goes into depression after Tamaki's father had her fired, until Tamaki manages to reveal her hidden kindness.
