!!Class 2-C

!!Tenma Tsukamoto

->'''Voiced by:''' Creator/AmiKoshimizu (JP) and Creator/LuciChristian (EN)


The main female character, a ditzy airhead with a crush on Karasuma.
* AlliterativeName: Tenma Tsukamoto. Only in English. In Japanese, the first two characters don't match.
* AllOfTheOtherReindeer: Majority of the boys at school don't find her attractive, mainly because of her apparent childishness.
* AnnoyingYoungerSibling: Inverted since she's the older sister, but she was this to Yakumo as a kid, though her intentions were always pure.
* AttentionDeficitOohShiny: She has the attention span of a schizophrenic goldfish.
* BalloonBelly: When she eats too much.
* BigSisterInstinct: Though she is the less mature of the two, she is nevertheless protective of Yakumo and fumes at the thought of anyone hurting her. She is also more than willing to give her relationship advice, though ill-informed.
* BookDumb: She has some pretty bad grades.
* CloudCuckoolander: Tenma...does not think like normal people. Needs to send her crush a love letter? Bow and arrow! Need to get out of the bathroom? Use plungers to suction cup down the wall!
* ConvenientlySeated: Tenma sits in the back seat next to the window, with Karasuma right behind her and Harima to her right.
* CuteClumsyGirl: She's generally known as the class klutz, though only a couple people find it cute.
* {{Determinator}}: Whenever Karasuma is involved. [[spoiler:She even decides to become a doctor to help him after he loses his memories.]]
* TheDitz: Tenma doesn't do well with anything that requires too much thinking.
* DoggedNiceGirl: She just wants to spend time with Karasuma. That's all.
* DumbIsGood: She is rather stupid, but is also friendly, willing to listen to people and help them if she sees they're down in any way, and is generally very sweet.
* EroticEating: To Harima, Tenma looks sexy while eating Pocky (well, [[BlandNameProduct Picky]]). To Eri, she looks like a squirrel.
* ExpressiveHair: A pair of [[HairAntennae antennae]] coming out the sides of her head. [[EpicFail Which she forgets to hide when she disguises herself]].
* FoolishSiblingResponsibleSibling: The foolish to Yakumo's responsible.
* GenkiGirl: Very much so, especially when she's a ShipperOnDeck.
** Its also to cover up that she's a StepfordSmiler.
* GirlishPigtails: Sort of.
* HiddenDepths: She surprises everyone with her mad skiing skills. She's also surprisingly talented at art (like, ironically, both of her potential love interests) and not too bad at Japanese history (probably because of her fondness for "Three to Get Killed").
* InformedAttractiveness: The way Harima sees her is different from the way any other character sees her.
** The problem is that many of the boys at school favour girls who appear and act to be older and sophisticated. Harima's cousin, Itoko, notes that Tenma is actually quite attractive by Japanese standards.
* InsaneTrollLogic: Tenma sometimes slips into this line of logic. The most blatant example is coming to the conclusion that she has to play the part of the princess in "Sleeping Beauty" after Karasuma gave her a turtle.[[note]] According to her since turtles are cursed with being slow, she has to play the cursed princess. This is based on a play on the Japanese word "noroi" which can be translated to both "slow" and "curse."[[/note]]
* TheMatchmaker: Lampshaded in the manga, saying she is only good at matchmaking. Of course, [[InformedAbility she's actually really bad at it]] due to her stupidity causing her to misunderstand everything she sees (most notably trying to pair Harima with several different girls [[ObliviousToLove without a clue as to why such a thing is futile]]).
* {{Joshikousei}}: In her school uniform, obviously.
* LethalChef: She cannot even get ''onigiri''[[note]] riceballs [[/note]] right.
* {{Miko}}: She dressed like this to [[LoveLetterLunacy deliver love letters to Karasuma]].
* NiceGirl: The ONE thing she has in common with Yakumo.
* ObliviousToLove: Tenma has no idea about Harima's feelings [[spoiler:until San Gakki.]]
* OlderThanSheLooks: She is often mistaken to be younger than her sister.
* PsychicPowers: Is telekinetic and can speak to ghosts (played for laughs).
* PutOnABus: She leaves the country to go after Karasuma.
* SiblingYinYang: Take a look at most of the tropes under her name, then compare them to Yakumo's. The Tsukamoto sisters are like night and day
* ShipperOnDeck: Tenma actively supports whoever Harima is trying to pursue... [[ObliviousToLove except she didn't know it was her.]]
** She also ships Harima with Yakumo, although she was against it at first.
* TaremeEyes: They show her cheerful and ditzy personality.
* WeaponOfChoice: Went on bow-and-arrow spree once to [[LoveLetterLunacy deliver love letters to Karasuma]], with [[ImprobableAimingSkills scarily good aim]], only beatable by Karasuma's dexterity.

!!Kenji Harima

[[caption-width-right:300:He's not as scary as he looks.]]

->'''Voiced by:''' Creator/HirokiTakahashi (JP) and Brandon Potter (EN)

The main male character, an aspiring mangaka who's head over heels for Tenma. Has a younger brother named Shuuji.
* AccidentalMisnaming: The guy at the manga office constantly calls Harima "Tasawa". Harima calls Karasuma "Torimaru" and Yoshidayama "Yoshida".
* AccidentalPervert: Mostly with Eri, and once during with Tenma during their first meeting.
* {{Adorkable}}: He's surprisingly nerdy and self-conscious, but it makes him incredibly endearing.
* AnguishedDeclarationOfLove: Mistakenly, to Eri. It still made her heart skip a beat though.
* AnimalTalk: After he ditches school in shame early on, he collects an entire zoo's worth of animals and learns to communicate with them.
* AntiMagic: He is at times immune to Yakumo's mind reading.
* AuthorAvatar: InUniverse, of his own manga. He seems to actually believe it's not as obvious as it is.
* BadassBeard[=/=]BadassMustache: Eri even calls him "hige" (beard in Japanese) and "whiskers" in the English translation. And for the badass part he's probably the toughest fighter in the series, since he can toss around every punk in town with ease.
* BadassBiker: He has a ''very'' nice bike, though he doesn't express most of the associated tropes.
* {{Bishonen}}: Surprisingly enough, with his shades and beard gone, Harima is pretty enough to be mistaken for a girl when his body below his neck is covered by water.
* BookDumb: Not very bright, getting graded very poorly in everything except art and sports class. Slightly subverted when he actually pretends to be even dumber than he is just so he can be in remedial classes with Tenma.
* ButtMonkey: If something bad can happen, it ''will'', and to him.
* ChasteHero: He's turned down Anegasaki's advances.
* ColorFailure: Harima goes pale after a rush to complete one of his manga, in a ShoutOut to [[Manga/AshitaNoJoe a certain boxing manga]]. Also occurred earlier in the first season when in despair after coming across Tenma happily eating together with Karasuma.
* CoolLoser: He's good-looking, strong, athletic and something of a chick magnet in school, but this falls apart because of his antisocial nature, numerous misunderstandings, and sheer idiocy.
* CoolShades: Such an iconic part of his character that no one recognizes him without them. [[spoiler:He met Tenma when he wasn't wearing them, and due to a misunderstanding, she thought [[DudeShesLikeInAComa he was trying to take advantage while she was unconscious]], so he wears them so she won't connect the two.]]
* CluelessChickMagnet: Got the two most popular girls pining for his affection, but is absolutely clueless about it. Justified as he only cares about winning Tenma's heart.
* {{Determinator}}: He ''jumped out of a plane'' in the manga when he thought Tenma was in trouble. And this is one of the more ''controlled'' things he's done.
* DoggedNiceGuy: His only desires in life are to publish his manga and settle down with Tenma.
* DudeLooksLikeALady: Was once mistaken for Mikoto when viewed from behind without his hair-band on, although he was sitting in a steam-clouded bath that covered him from the neck down.
* DumbMuscle: Harima may not be able to read your name very well, but he can definitely bring a beatdown upon you.
* ExpositoryHairstyleChange: He grows a beard so that Tenma won't recognize him, which Eri accidentally cuts off.
* FaceOfAThug: And how!
* ForgottenFirstMeeting: Shown in ''Z'' that he had met the Tsukamotos when they were kids and he may have been the reason Yakumo is the soft-spoken girl she is today.
* FriendToAllLivingThings: Had an entire zoo living in his apartment.
* GunsAkimbo: When fighting Hanai in the final battle of the ''Film/BattleRoyale''-style mock war.
* HeCleansUpNicely: The FaceOfAThug goes away (mostly) once he shaves and removes the glasses.
* HiddenDepths: Badass delinquent who is a talented artist, and a lovesick idiot.
* HotBlooded: He has a tendency to make loud declarations while something explodes in the background. He would not be at all out of place in a shonen fighter manga.
* HurricaneKick: Not really. Instead, played for PunnyName. When saving Tenma from a thug, Harima yells out this trope, but he doesn't spin around (just performing DynamicEntry). Instead, this is used to take note on 'What if we shorten Harima Kenji', which becomes '[=HariKen=]', which is how the the English word "Hurricane" is pronounced/spelled in Japanese.
* IDidntMeanToTurnYouOn: When Eri asked him about his preferences in women[[note]]Actually this was Tenma's idea as [[ShipperOnDeck she intends to pass the information to Yakumo]] but asked Eri to do it because she thinks it might be suspicious if she asked[[/note]], he said he finds girls who can't swim cute, and is a sucker for girls with pigtails. Given that his answer about the pigtails was intended to impress the pigtail-wearing Tenma[[note]]who he saw hiding behind a prop[[/note]], he failed to realize that Eri also hits both criteria of his preferences: namely not being able to swim and wears her hair in pigtails.
* InSeriesNickname: Eri calls him "Hige" or "Beardy" in the manga and the Japanese sub, "Whiskers" in the English dub.
* IShallTauntYou: Invoked for drama and [[PlayedForLaughs comedy]] during the survival games mini-arc, when he corners Mikoto and holds her at gunpoint. just long enough for Hanai to try to save her. Just as he gets within a few feet of them, Harima pulls the trigger and "kills" her, then smugly tells him he was too late, before fleeing the scene.
* IWantMyBelovedToBeHappy: Early on, he resolves to give up on Tenma when she seems happy with Karasuma.
* JerkWithAHeartOfGold: He's a bit of a prick and he'll fight anyone who pisses him off, but for the most part he's an extremely good person who would do anything for his friends.
* LaughingMad: When Tenma thought Harima and Eri were a couple.
* LoveMakesYouDumb: He may not be the sharpest tool in the shed to begin with, but in anything regarding Tenma, he drops about fifty IQ points.
* MadeOfIron: As Itoko points out, being hit by a truck going 40mph and getting out of the hospital in only ten days is fairly impressive.
* ManlyTears: A few times, such as when he thinks his manga has failed.
* MistakenForGay: A RunningGag with him and Tani-sensei.
* MrFanservice: He gets lots of shirtless scenes to show off his ripped body. During the BeachEpisode, Eri accidentally walked in on him naked, and for the next few days can't stop thinking of... ''that''.
* NotSoDifferent: Although he and Hanai consider each other rivals due to the fact that he is a delinquent and Hanai is a class representative, they've got more in common than they'd like to admit -- they're both obsessed with a particular girl (both of whom happen to be sisters), HotBlooded and prone to misunderstandings, and have been known to come up with near-identical plans independently.
* ObliviousToLove: See CluelessChickMagnet. He can be excused for not realising he'd managed to attract Yakumo's affections as she is aware of his feelings for her sister Tenma and keeps them to herself as a result. On the other hand, it's really rather clueless of him to not pick up on Eri's feelings, as she doesn't conceal them nearly as well. He at least has the excuse that she's so {{Tsundere}} that it's hard for him to even imagine that the beautiful rich girl would fall for a rowdy delinquent like him like him.
* PaperThinDisguise: He dressed up as a fortune teller and neither Mikoto nor Eri were fooled. On the other hand, almost nobody can recognize him without his glasses.
* RetiredBadass: His love for Tenma has caused him to abandon his delinquent ways.
* RightForTheWrongReasons: He correctly deduced that Yakumo can read minds, coming to this conclusion by noting that her guesses about the nature of his manga are too spot on, despite his best efforts of hiding it. He's right about the reading minds thing, but is completely wrong about how Yakumo figured out his crush on Tenma.[[note]]she noticed how the main characters look like him and Tenma, and noted that said main characters wound up in a relationship[[/note]]
* SatelliteLoveInterest: Deconstructed. He starts to forget why he likes Tenma in the first place, and also starts to believe his attraction to her is almost compulsive.
* ScarsAreForever: He has a scar on his back which he got from saving Tenma from a hoodlum.
* SelectiveObliviousness: On so many things. He fails to notice Eri or Yakumo's feelings for him, just for starters.
* ShipTease: Gets a lot with Eri, more than a little with Yakumo, and a ''tiny'' bit with Tenma.
* ShirtlessScene: Boatloads of them.
* SlowMotionFall: Every time Tenma mistakes him having a relationship with someone else.
* SpannerInTheWorks: Harima's love for Tenma causes him to sabotage his plans to get together with her.
* SpeaksFluentAnimal: What attracts Yakumo to him in the first place.
* StalkerWithACrush: He's a rare sympathetic example for a male character, as he's the male lead, and not a bad guy at all, just a lovably bumbling fool for love. This is also downplayed that he doesn't always follow Tenma around.
* StarvingArtist: It got to the point in ''Z'' where [[spoiler:Eri agreed to finance Harima if he married her]].
* SunglassesAtNight: He even wears them in the hospital.
* VitriolicBestBuds: With Hanai. They argue and fight over everything, and Harima often messes around with Hanai for no real reason, but underneath that there's a rock-hard friendship and genuine trust.
* WalkingTheEarth: He disappeared during the TimeSkip, earning a living as a traveling musician.
* WillTheyOrWontThey: Gets this alternatively with Eri and Yakumo. In the manga, he eventually [[spoiler:ends up with Eri. Probably. [[GainaxEnding It was confusing]]]].

!!Oji Karasuma

->'''Voiced by:''' Hiroki Konishi (JP) and Creator/EricVale (EN)

The school's weird, quiet guy who loves curry and is the subject of Tenma's affections.
* AccidentalMisnaming: Though it [[TheStoic doesn't seem to bother him]], Harima calls him Torimaru, an AlternateCharacterReading of his name. The dub has Harima calling him "Kama Sutra" once or twice, but mostly giving him a HeyYou.
* [[CosplayOtakuGirl Cosplay Otaku Dude]]: Akira's rival in this hobby.
* CreepyMonotone: The only way he ever speaks.
* CrouchingMoronHiddenBadass: He easily dodges Harima's punch in front of the curry restaurant. Also when [[spoiler:he fights Harima pretty much to a standstill in the later chapters of the manga]]. Not to mention that he singlehandedly racks up quite a few "kills" in the ''Film/BattleRoyale'' parody.
* FingerSuckHealing: Karasuma does this for Tenma.
* LaserGuidedAmnesia: [[spoiler: Karasuma abruptly loses his memories, forcing Tenma to leave to the United States to look after him. However, it's heavily implied at reunion that some of his memories are starting to return.]]
* LimitedWardrobe: Most of the characters have a few different sets of clothes. Karasuma is only ever seen in his school uniform.
* ObliviousToLove: Karasuma doesn't even seem aware of Tenma's affections... [[spoiler:[[ObfuscatingStupidity or does he?]]]]
* TheQuietOne: He never raises his voice above a whisper.
* SchoolUniformsAreTheNewBlack: See LimitedWardrobe.
* TheStoic: Nothing can faze him. Not being attacked by Harima, not finding a love letter in his locker, nothing.
** NotSoStoic: [[spoiler:To the point where he's barely recognizable.]]

!!Eri Sawachika

->'''Voiced by:''' Creator/YuiHorie (JP) and Creator/LeahClark (EN)

The wealthy, half-British member of Tenma's clique, who finds herself falling for Harima after he mistakenly proposes to her.
* ActionGirl: Although normally she doesn't like physical activity, she's considered to be one of the more athletic girls in her class. Apparently, she's also the fastest runner in her grade.
* ArrangedMarriage: She was supposed to marry Shawn but she convinced Harima to propose to her.
* AuthorAvatar: Rumor is she is based on the author's wife.
* BigFancyHouse: Eri points out to Harima (manga only), that it's her father's house and not hers.
* ButNotTooForeign: Half-Japanese, half-English. Her mixed heritage makes her attractive to the Japanese and an object of derision to Europeans.
* ClingyJealousGirl: [[DeconstructedTrope Deconstructed]]. Any time it looks like one of her friends in interested in Harima, she turns stone cold and nearly ruins her friendship.
* CryCute: A quiet version, when she's been abandoned in the rain.
* CurtainsMatchTheWindow: Gold eyes and blonde hair.
* CuteLittleFangs: Sometimes, when she's being passive-aggressive.
* DeathGlare: [[http://i303.photobucket.com/albums/nn139/animangamania/vlcsnap-2011-02-25-21h22m27s160.png This]], which makes Harima obey her immediately.
* DefrostingIceQueen: Towards Harima. Slowly. ''[[{{Tsundere}} Very]]'' slowly.
* DudeMagnet: The biggest in the series. She is considered the most popular girl in school among the guys. It's to the point she regularly turns Guys down.
* GirlishPigtails: To emphasize that she's not quite as mature as she likes to pretend.
* GoodAngelBadAngel: When she invited Harima to her house.
* LethalChef: Only surpassed by Tenma.
* LonelyRichKid: Until Mikoto forcibly dragged her out of her shell.
* MaybeEverAfter: [[spoiler:The final chapter of ''Z'' shows a scene of Harima and Eri bringing their child to visit the Tsukamotos and Oji in the hospital, but it is presented in such a way that it may or may not be a certain character (Max, Eri's old friend from Britain) imagining it.]]
** In the most recent chapters that actually take place eight years after school rumble, Harima is still oblivious to her feelings.
* MsFanservice: The author loves to show Eri looking good in uniform, casual wear, bikini, evening gown, and of course, naked.
* SleepCute: When she and Harima are stuck at a shrine overnight, she falls asleep on him. Harima even notes that, for a moment, he can forget that she's a [[LongList rich, selfish, egotistical, stuck-up, arrogant brat]].
-->'''Eri:''' ''[sleep talking]'' Mikoto, what are you talking about? Whiskers totally fails at life.\\
'''Harima:''' Okay, moment over, back to being mortal enemies.
* SoBeautifulItsACurse: All anybody sees of her are her stunning looks, and only her close circle of friends see her for who she is. Everyone else sees her as just a beautiful face, and she has quite the complex about this.
* TheOjou: Harima even calls her one.
* {{Tsundere}}: Switching moods [[DeconstructedTrope almost ruins her friendships]]. She gets attracted to Harima because she doesn't have to act nice towards him.
* TsurimeEyes: The first hint to her personality.
* WillTheyOrWontThey: Quite a bit with Harima. In the manga, [[spoiler:they do but only in Z. Eight years later in the main time line however they have yet to]].

!!Mikoto Suou

->'''Voiced by:''' Creator/HitomiNabatame (JP) and Creator/BrinaPalencia (EN)

A member of Tenma's clique and Hanai's long-time friend.
* ActionGirl: One of the top martial artists in her family's dojo. Also, seen during the war games mini-arc, where it was known that she and Hanai would be the two to watch out for.
* BareYourMidriff: In [[http://i47.photobucket.com/albums/f154/harimadez/mikochin.jpg this image]], her midriff gets special attention.
* BoisterousBruiser: Mikoto can be pretty rowdy at times, to the point of [[NoIndoorVoice getting carried away.]] But it mainly shows in her athleticism.
* BoobsOfSteel: Has one of the largest bust sizes in the class, in addition to being one of the best athletes in her class. Though all Imadori cares about her boobs, which he estimated were at least size D.
* ChildhoodFriends: She and Hanai know each other from way back and even grew up together as sparring partners at her family's dojo. Which is why she's one of the few people who can kick his butt.
* FaceDeathWithDignity: She was one of the last to "die" during the survival games, due to being out of ammo just as she ran into Harima. Though she tried to save herself by making a grab for Akemi's gun, Harima kicks it out of reach. At which point, she resigned herself to her fate and told him to finish it.
* FriendlyRivalry: As noted in the preceding entry, she and Hanai have been sparring partners since childhood. Which turns competitive on occasion.
* GirlNextDoor: In terms of looks and her personality. She's basically the most down-to-earth member of the cast.
* [[HeIsNotMyBoyfriend He is NOT My Boyfriend!]]: Invoked whenever anyone mistakes her and Hanai for being an item, or in case anyone asks.
* HugeSchoolgirl: She's the tallest girl in her class and one of the tallest at the school, which is part of the reason most guys are intimidated by her.
* TheLadette: She's essentially [[OneOfTheBoys 'the guy']] among her group of friends, being that she's the most athletic girl at their school, one of the few people capable of beating Hanai, good at sports (and arcade games), and she likes knockin' back brewskies every now and then.
* NoGuyWantsAnAmazon: Despite her looks and her figure, most guys are put-off by her height and athleticism. Asou was one of the few exceptions and briefly dated her, though it's implied he broke up with her [[SoreLoser because she kept beating him at video games]][[note]]see the SoreLoser entry in Asou's section[[/note]].
* OfficeLady: Her perceived future career.
* OneOfTheBoys: Though the boys stopped treating her as one of them as her chest grew out, she kept the personality.
* ShipperOnDeck: Ships Harima and Eri. Most obvious when Harima is staying at her house for Christmas.
* ShipTease: Alternatively with Hanai and Asou.
* SuperDrowningSkills: In the anime version, she and her friends don't know how to swim. Which is why they lost hilariously after accepting a challenge to a swimming contest [[Funny/SchoolRumble and sank like stones.]]
* TomboyishPonytail: She fashions her hair in a ponytail wherever she's sparring with Hanai.
* VictoriousChildhoodFriend: By the time of ''"School Rumble Z"'' she and [[spoiler: Hanai]] are married.
* YouGottaHaveBlueHair: As seen in her folder picture.

[[caption-width-right:200:Don't expect her to smile.]]
->'''Voiced by:''' Creator/KaoriShimizu (JP) and Creator/TrinaNishimura (EN)

Last member of Tenma's clique and the quiet one of the group, whose half-sister Motoko is in the hospital.
* ActionGirl: She may or may not be a spy.
* {{Bifauxnen}}: Pulls off wearing boyish attire (even tuxedos) quite well.
* BoyishShortHair: Short hair for a {{Bifauxnen}}.
* CameraFiend: An aspect of her [[TheGadfly Gadfly]] personality.
* TheChessmaster: She can make people do whatever she wants using a word or information that they want. The best example is her setting up the survival game using just a few choice words on Harima and Hanai.
* TheComicallySerious: Always cracks a joke or dresses up in different outfits, and she still keeps that poker face on.
* CosplayOtakuGirl: Her one ''really odd'' quirk.
* DeadpanSnarker: While wearing a straight face too.
-->'''Akira:''' Why do you fail at life?
* EmotionlessGirl: Lampshaded. On her birthday, Tenma asks her to show her smile.
* TheGadfly: She really enjoys messing with everyone. She expertly set up the Culture Festival War, which she secretly taped and edited into a film as her Culture Festival project.
** {{Troll}}: She has played pranks on people solely because she can. The victim of most of her antics is Hanai.
* GenreSavvy: Finds a naked Harima restraining a nearly naked Eri, and rather than take everything as it looks, immediately figures out that it's because Eri stumbled into the room while Harima was looking for his clothes and he grabbed her in a panic before she could scream.
* KnifeNut: Manga only. She has a knife for everything. She even keeps a spare one.
* MissionImpossibleCableDrop: During the school play to steal Harima's kiss.
* SacredFirstKiss: Steals Harima's, then [[InsaneTrollLogic offers to give it back to Yakumo]].
* SchoolSwimsuit: When she and her friends met Nara and his friends.
* TheStoic: She smiled ''once''. [[TheUnreveal Offscreen.]]

* WhenSheSmiles: On Tenma's birthday, Tenma demands to see her smile. No one else sees it, but Tenma is certainly impressed.

!!Haruki Hanai

* AlliterativeName: '''H'''aruki '''H'''anai.

* ChickMagnet: Heavily implied to be one, with [[spoiler:Tsumugi being confirmed as to liking him and Akira being heavily implied by the end]].
* ChildhoodFriends: With Mikoto.
* ClassRepresentative: He takes his duties seriously, but can get distracted by Yakumo or his rivalry with Harima.
* CrouchingMoronHiddenBadass: Despite his comic role, as a practitioner of Kenpo since childhood, Hinai is one of the best hand-to-hand combatants in the series and is matched only by the likes of Harima, Mikoto, and Harry [=McKenzie=].
* CovertPervert: He tries his best to be a very moral and strict character, but he is human with his own perverted moments and thoughts.
* DreadfulMusician: Due to not having practiced since he was a kid.
* EstablishingCharacterMoment: In the episode where we find out about Yakumo's mind-reading ability, every boy is thinking about how beautiful and perfect she is while keeping a straight face. Then Hanai shows up, thinking the same thing -- the difference is he actually ''says'' it. From the moment we meet him, we know he is honest to a fault.
* [[PutOnABus Floated Away On A Kite]]: When the anime OvertookTheManga. He made some appearances but stopped being an important character. {{Lampshaded}} in the manga when he apparently has no idea how he came back.
* HamToHamCombat: With Harima sometimes.
* GunFu: The survival games mini-arc culminates in a scene straight out of ''Film/{{Equilibrium}}'', where he and Harima displayed their skills in the use of Gun Katta.
* HotBlooded: Just like Harima. Though his backgrounds tend to be crashing waves rather than explosions.
* IncomingHam: Tends to enter scenes with "I, Haruki Hanai, ___!"
* LargeHam: Makes loud and impressive declarations regularly.
* NerdGlasses: Subverted in that he isn't actually a nerd, just an [[GeniusBruiser extremely intelligent badass]].
* NotSoDifferent: Although he and Harima consider each other rivals due to the fact that he is a class representative and Harima is a delinquent, they've got more in common than they'd like to admit. They're both obsessed with a particular girl, HotBlooded and prone to misunderstandings, and have been known to come up with near-identical plans independently.
* RousingSpeech: Lampshaded during the class meeting following the survival games arc. Some of the students had no idea what he was talking about, yet said they felt motivated somehow.
* ScaryShinyGlasses: At times.
* ShipperOnDeck: Gives Mikoto a chance to dance with Asou after she misses the school play.
* SunglassesAtNight: During the Wargames arc.
* TrainingFromHell: He gets this from an old man he doesn't even know.
* [[spoiler:VictoriousChildhoodFriend: With Mikoto.]]
* VitriolicBestBuds: With Harima. They argue and fight over everything, and Harima often messes around with Hanai for no real reason, but underneath that there's a rock-hard friendship and genuine trust.
* WeddingsInJapan: Mikoto and Yakumo both participate in Western-style weddings, both with Hanai as the groom.
* WhoWouldBeStupidEnough: When he finds out that Tsukamato (Tenma, but he thinks it's Yakumo) is going to an engagement meeting, he rushes off after them on his bicycle.
-->'''Nakamura:''' Please, they're hundreds of kilometers away. He'd have to be a lunatic--\\
'''Mikoto:''' Trust me, you have no idea.

!!Kyousuke Imadori
->'''Voiced by:''' Creator/DaisukeKishio (JP) and David Trosko (EN)

The class's second-ranking pervert.
* AbhorrentAdmirer: To Mikoto, who finds his fixation with her breasts to be irritating.
* BigBrotherInstinct: Instantly bonds with Karen's younger brother over a children's show.
* {{Bishonen}}: Subverted. He only looks like one when he gets serious. Otherwise, he usually looks like an idiot.
* BrilliantButLazy: One of the fastest runners in his class. Moreover, he's an excellent swimmer: his endurance and ability is such that he can keep up with Mikoto in a two-mile swim back to mainland. He can also grapple Hanai into a stalemate. The only thing holding him back is his lack of seriousness.
* BuxomIsBetter: Firm believer in this.
* ChickMagnet: In his earliest apparitions at least. This characteristic its later dropped.
* ChivalrousPervert: Towards Karen, more so once he discovers that [[HiddenBuxom she's actually bustier than her uniform shows]]. He also tends to gravitate towards Mikoto and Lala, if only because of their bustiness. But however perverted he may be, there are lows that he will never stoop to: upon hearing that Karen's date was bringing her to a shady night club, he immediately went to put a stop to it.
* {{Flanderization}}: He went from girl magnet to ManChild, although he still retains elements of the former.

A cute girl with scary strength. Has a younger brother named Kousuke.
* BadassAdorable: Very much so.
* BoobsOfSteel: Because she keeps her breasts bound, she looks like your typical "[[BadassAdorable extremely powerful flat chested girl]]" most of the time, but in reality she's quite developed in that particular area.
* CuteBruiser: Not that she's the only fighting girl in the series, but she pretty much ''defines'' the trope in this series.

* ButtMonkey: He tends to get casually beaten up by Harima.
* {{Delinquent}}: And aspires to be the number-one in the school.

Star player of Yagami High's men's basketball team, who dated Mikoto for a short time.
* TheAce: Athletic, good-looking, intelligent, and a great chef to boot. Marred only by the fact that he doesn't come anywhere close to being a major character.
%%* {{Bishonen}}
* TheComicallySerious: Even amid the rest of his class's antics, he remains stoic, often to comedic effect.
* EnsembleDarkhorse: In-universe, he's referred to as a "dark horse". He's not as prominent as the other male characters in the series, although he is among the most athletic students in his class. He's also popular among the girls.
* MauveShirt: In the survival game. We'd just gotten to know him a little bit, but he wasn't even close to a main character by the time he "died".

* BromanticFoil: To Asou.
* ButtMonkey: His life sucks almost as much as Nara's does, although this is often his fault because he keeps acting like an idiot and a loser.

* {{Flanderization}}: Suga's loserliness was increasingly emphasized in the manga to the point where he started hanging out more with Nishimoto rather than Asou.
* {{Hypocrite}}: He's completely shocked whe he finds out that Midori is dating with another man behind Shigeo's back. She insulted her calling her a black ship, and he's ready to calling him by the phone informing him about the situation.

* RedOniBlueOni: Red to Asou's blue.
* ThoseTwoGuys: With fellow basketball player Asou.

!!Mai Otsuka

Acting substitute Class Representative of Class 2-C in the event Hanai can't perform his duties, in spite of her friend Tsumugi supposedly filling that role.
* ClassRepresentative: She is one for nine years straight until Hanai came in. Still that doesn't stop her from exercising some authority in class whenever Hanai isn't around.
* DrillSergeantNasty: Gives off a bit of this vibe when yelling at everyone.
* GenkiGirl: She's quite passionate with her (self-appointed) duty.
* HiddenBuxom: According to the 2-C female information segment on season 2 episode 1, her rack is pretty impressive under their school uniform. Even Imadori is shocked upon learning this.

!!Class 1-D

!!Yakumo Tsukamoto
->'''Voiced by:''' Creator/MamikoNoto (JP) and Creator/CaitlinGlass (EN)

Tenma's younger, far more responsible sister. A sweet, kind and soft-spoken girl who also works part-time at a CosplayCafe. She develops feelings for Harima when she starts helping him with his manga.
* TheAce: She's intelligent, athletic, and an excellent cook.
* BeautifulDreamer: How Hanai and Sarah first saw Yakumo.
* BerserkButton: Never insult Tenma in her presence.
* BewareTheNiceOnes: Nobody insults her friends, classmates, let alone her sister, and still not sense her seething with anger.
* [[BigLittleBrother Big Little Sister]]: Orders of magnitude more mature than her big sister.
* BlessedWithSuck: She can read the mind of anyone who likes her, except Harima.
** Somewhat subverted when she first meets Harima: she is able to read his mind somehow (because back then, his only true interest was Tenma), but all she sees is an ellipsis.
* CryCute: [[spoiler:She breaks near the end of the first manga, admitting she wanted to connect with more people and become less of a burden to her sister. In contrast, the ghost (her subconscious), bursts out ''laughing''.]]
* DaddysGirl: One of the reasons she's attracted to Harima is that he looks like the Tsukamotos' father from behind.
* DudeMagnet: To the point of being the school Idol, as tons of his throw themselves at her. Just ask Hanai.
* TheEmpath: She can read minds (literally, she sees thoughts as words floating in the air) of people who like her. Only Harima is immune to her mind reading ability.
* EvenTheGirlsWantHer: Thanks to Sarah and Akira.
* FoolishSiblingResponsibleSibling: The responsible to Tenma's foolish.
* HeavySleeper: She does the housework, goes to school and has a job so it's no wonder she gets sleepy. It's also a DeconstructedTrope, since it interfere with her daily chores.
* HeterosexualLifePartners: With Sarah.
* IWantMyBelovedToBeHappy: We're not quite sure if Harima ended up falling in love with Eri or not, but Yakumo's thoughts in Chapter 9 of ''Z'' that she truly believes that Eri is the only one who can break down the wall Harima has put up around his heart.
* TheIngenue: Her telepathy makes her painfully aware of impure thoughts towards her but she is still unaware of how to get into a relationship.
* InSeriesNickname: Harima calls her "imouto-san" as a way of distinguishing her from Tenma. This actually borders on AffectionateNickname because Harima almost never uses polite speech (unless forced to), and only does so when he talks to Yakumo.
* {{Meido}}: When she works she wears this outfit. It gives her a cute appeal.
* NiceGirl: All she wants is her sister to be happy, even if that means letting her have [[IJustWantMyBelovedToBeHappy the only boy she's interested in]].
* PlayboyBunny: Subverted -- Hanai imagined she's about to wear one; turns out she's wearing an oversized rabbit costume.
* TheQuietOne: She never raises her voice.
* SchoolIdol: She is ranked as the most popular freshman in their school and one of the most popular girls overall. Many people think she's just not aware of how popular she is due to her quiet demeanor.
* SempaiKohai: She addresses most characters as sempai, due to them being a grade higher than she is.
* ShrinkingViolet: She starts almost all her sentences with "Um".
* SiblingYinYang: She is everything Tenma wishes she was, and also everything Tenma isn't. Perhaps the only traits both sisters share are that both of them are nice people and both have problems expressing their feelings to the people they love.
* SoBeautifulItsACurse: Every male she meets (except Harima) is instantly infatuated with her, and due to her mind reading, she is embarrassingly aware of this.
* SupremeChef: Her cooking is remarked as being very delicious.
* TookALevelInKindness: Retroactive example -- [[spoiler:she used to be quite the AnnoyingYoungerSibling to Tenma, until her encounter with Harima changed her life]].
* TsurimeEyes: A subversion or a double? Considering her childhood personality, it makes sense.
* WhenSheSmiles: She's beautiful enough even while maintaining a calm expression under most circumstances. In the few moments when she actually smiles, she looks like a goddess.
* WillTheyOrWontThey: With Harima. In Z, [[spoiler:they don't.]].
* YamatoNadeshiko: A quiet and polite japanese schoolgirl that you should still beware of.

!!Class 2-D

!!Harry Mackenzie
->'''Voiced by:''' Creator/NobuyukiHiyama (JP) and Creator/JasonLiebrecht (EN)

American exchange student. His name sounds like Harima's when pronounced in Japanese. Actually has quite a bit in common with Harima besides that, too. Popular with the ladies.
* TheAce: Handsome, charming, strong in a fight.
* BadassBiker: Early mentions of him are that he rides a bike and kicks ass. This leads to confusion with [[NamesTheSame Harima Kenji]], who does the same.
%%* {{Bishonen}}
* CharClone: Visually resembles Char's Quattro Bajina persona from ''Anime/MobileSuitZetaGundam''... and his bike is gold, just like Quattro's Hyaku Shiki.
* ChekhovsGunman: His name is first heard in episode 1 leading Harima to think that he passed.
* CoolShades: Red shades, making him resemble [[CharClone Quattro Bajina]].
* {{Expy}}: see CharClone.

!!Lara Gonzalez
->'''Voiced by:''' Creator/YuuKobayashi (JP) and Creator/MonicaRial (EN)

Mexican exchange student and Karen's wrestling rival.
%%* BigEater
* BoobsOfSteel: Imadori wouldn't be interested in her if she weren't well-endowed. And she wouldn't be able to kick his ass if it weren't for this trope.
* ButNotTooForeign: It's implied she's half-Japanese.
* EarlyBirdCameo: She is first seen wrestling a masked Tenma, who volunteered to become Karen's substitute so she can go on her date with Imadori.
** Even earlier, she is shown in the ending credit sequence.
%%* ExpositoryHairstyleChange
* {{Expy}}: Like much of her class, an Expy for a Gundam character. In this case, Lalah Sune.
* FriendlyEnemy: Her antagonism toward Karen softened during the show's run.
* HiddenDepths: Harry once caught her doing cheerleading routines hidden from everyone's view. When she was doing it in the open earlier, everyone thought she was doing it against her will [[EmotionlessGirl given her lack of expression]].
* HotBlooded: Rare female example. She ''shouts'' nearly everything she says.
* HugeSchoolgirl: Exceptionally tall.
* JerkWithAHeartOfGold: Tends to be incredibly abusive and callous in response to the slightest provocation, but shows a soft side every now and then, especially towards Karen, her self-proclaimed rival. And to be fair, some of her victims did deserve a beating.
* MommyIssues: She initially hated Karen with a passion because the latter shared the same name as her mother, who abandoned her at an early age.
* NoIndoorVoice: Yells most of her lines.
* NoSocialSkills: Her aggressive attitude tends to scare others away. It doesn't help that she is tall and very intimidating, in addition to being visibly foreign and unfamiliar with Japanese customs. On the flipside of things, she does tone this down during her date with Imadori.
* PerpetualFrowner: So much so that Imadori risked getting his ass beat just so he can make her smile.
* RousingSpeech: She convinced her team to play against the Outlaw basketball team.
-->'''Lara:''' Why have we been practicing? For honor? For glory? No, for victory!
* SpicyLatina: HotBlooded, NoIndoorVoice, and quick to fight.
* WhenSheSmiles: She can be very charming when she does smile.

!!Masakazu Tougo
->'''Voiced by:''' Creator/HirokiYasumoto (JP) and Creator/TravisWillingham (EN)

Class Representative of 2-D. He tends to burst into long inspirational speeches. His father is a diplomat, so he brags he's been to the United States. His younger sister Haruna is a friend of Yakumo. Possesses great charisma and can talk people to doing his bidding quite easily.
* ClassRepresentative: He primarily uses his position to whip his class into a frenzy.
* {{Expy}}: Like Harry, he is like a black-haired [[Anime/MobileSuitGundamStardustMemory Anavel Gato]].
** He looks a bit like [[Manga/UruseiYatsura Shutaro Mendou]], too.
* HeyThatsMyLine: His main method of stealing Hanai's thunder.
* HotBlooded: See him "whip his class into a frenzy."
* LargeHam: With extra ham on the side. Its impossible to find a single line he speaks where he ''isn't'' hamming it up (which is annoying to Harima, since that often cuts in on his hamboning time)
* {{Leitmotif}}: ''[[{{Eagleland}} Oh say can't you see,]] [[NationalAnthem by the dawn's early light...]]''
* NonStandardCharacterDesign: In the manga especially, he's drawn more like the shonen heroes he's designed to parody.
* RousingSpeech: He's really good at this but sometimes [[CharacterFilibuster goes overboard]].
* ShirtlessScene: Intentionally. He loves his physique.
* SitcomArchnemesis: To Hanai.
* TestosteronePoisoning: His courage to take on things head on is almost [[SuicidalOverconfidence suicidal]].
* TrueArtIsIncomprehensible: InUniverse -- When the school play starts going haywire, he thinks it's a glorious avant-garde performance.

!!Noboru Tennouji
->'''Voiced by:''' Tomoyuki Shimura (JP) and Creator/SonnyStrait (EN)

Delinquent extraordinaire and Harima's nemesis.
* BaldOfEvil: "Evil" might be a bit strong for a mere high school thug (and he's shown to have a rather well-hidden sensitive side) but in most of his appearances he's a nasty, violent bully without a stitch of hair on his head.
%%* TheBrute
* {{Gonk}}: Especially compared to handsome Harry, masculine Tougou, and sexy Lara.
* TeamRocketWins: beats Harima once, when the latter was [[HeroicBSOD in despair]] after finding out Tenma liked Karasuma.
** VictoryIsBoring: However, because Harima [[WorfHadTheFlu wasn't himself]], he was unable to enjoy it
* [[UglyGuysHotDaughter Ugly Guy's Adorable Sister]]: His little sister Mio, who, ironically, has a crush on Harima's younger cousin Shuuji.
* YourSizeMayVary: Done intentionally, but when he shows up during the kibasen at the sports festival, he's the size of a [[Manga/AttackOnTitan titan]] and sweeps away entire ''rows'' of opponents with one casual swing of his giant arm. Obviously exaggerated for dramatic purposes.

* BeautyMark: Right under the left side of her mouth.
* [[CoolBigSis Cool Older Cousin]]: Functions as one towards Harima, more so when he had to stay at her place.

* TheyCallMeMrTibbs: Constantly reminds her cousin to call her Itoko-sensei at school.
