The following tropes can be applied to the characters of the {{Main/manga}} and {{Main/anime}} series ''Manga/{{Gravitation}}''.

[[foldercontrol]]

[[folder: Bad Luck]]
!'''Shuichi Shindou'''
->'''Voiced by:''' Creator/TomokazuSeki (Japanese), Rich [=McNanna=] (English)

-->'''Yuki:''' ''Quiet! I haven't cried in six years and my head is really killing me.''
-->'''Shuichi:''' ''Six years? You're just too cool! As for me, I cry at least once a day. Man, that's just mega-cool! It's like you have a dark past or something! Oh, right. You really do. Hahahaha!''
[[quoteright:250:http://static.tvtropes.org/pmwiki/pub/images/Shuiichi_594.jpg]]

* {{Adorkable}}
* AdaptationDyeJob: The anime adaptation ran with an interpretation of the color schemes Murakami likes to use in his color illustrations, and also changed his brown eyes to green.
* BareYourMidriff: The stage outfit he wears in the [=TV=] series is the most prominent example, but Murakami didn’t start favoring this look until she veered away from his original design basis (Koshi Inaba of B’z) and TMRevolution became a more dominant influence in Shuichi’s look.
* CampGay: To a slight degree.
* ClosetKey: For his ‘’own’’ ClosetKey, even. Shuichi’s influence is what forces Yuki to accept and extricate his sexuality from his past trauma.
* {{Crossdresser}}: Not quite unwholesome enough to be considered [[CreepyCrossdresser creepy]], but it’s nearly always for reasons that involve trying to seduce Yuki. He thinks it’s a much better look on him than it actually is.
* DisguisedInDrag: When he pretends to be [[spoiler: Ayaka]] so he can get Yuki’s ArrangedMarriage called off.
* DudeLooksLikeALady
* EvenTheGuysWantHim
* {{Flanderization}}: His {{Keet}} tendencies overtake his characterization from about the third volume on.
* {{Gayngst}}: When it seems Yuki is rejecting him (at several points), his default question is "Is it because I'm a guy?"
* HairColorDissonance: In the manga, his hair is black and generally reads that way in the actual text, but Murakami renders this in various shades of pink and red in her color illustrations. This seems to be an artifact left over from recycling the character designs from her B’z {{Yaoi}} {{Doujinshi}} for Bad Luck- Koshi’s hair (which in real life varies between black and shades of brown) is usually rendered in the same shade of pink as early color illustrations of Shuichi. Oddly, during the period when he bleaches it blonde, the color illustrations accurately represent his hair color.
* HorribleJudgeOfCharacter: So much so that probably the only person he actually judges correctly upon first meeting is Reiji. This is also what gets him trouble with Taki.
* ImpossiblyTackyClothes: The outfits that Reiji puts him in.
* IwantMyBelovedToBeHappy: He was willing to give Yuki up when he thought [[spoiler: Ayaka]] would make him happier; it backfired on him because ''she'' was actually testing how hard he would fight for Yuki.
* {{Keet}}: He's the page image for a reason.
* LoveMartyr
* MoodWhiplash: He's pretty much the personification of this trope.
* OlderThanTheyLook
* PuppyDogEyes
* SailorFuku: Wears one once in a futile attempt to be sexy for Yuki.
* {{Stripperiffic}}: His performance outfits are sometimes this. Murakami also really likes to put him this type of outfit for the book and chapter covers of the manga. Some are meant to be stage costumes, though not all.
* StupidSexyFlanders
* SuperDeformed: He falls into this at several points, sometimes with LittleBitBeastly mixed in.
* ThereWasADoor: You can't help but wonder how he's not in debt after all the walls he's had to pay for.
* {{Uke}}
* {{Wimpification}}: Canon example
* WholesomeCrossdresser
* WhoWearsShortShorts: Shuichi wears short shorts.

!'''Hiroshi Nakano aka Hiro'''

[[folder: Nittle Grasper]]
!'''Tohma Seguchi'''
->'''Voiced by:''' Creator/AiOrikasa (Japanese), Bill Rogers (English)
[[quoteright:250:http://static.tvtropes.org/pmwiki/pub/images/Seguchi_4029.jpg]]
* AffablyEvil: When at his worst. Granted, "evil" isn't really the right word for it, but then again, neither is [[{{Yandere}} "sane"]].
* AlwaysCamp
* BerserkButton: Do ‘’not’’ even think about so much as looking at Yuki funny if you value your safety. Especially don’t think about dressing up as the [[spoiler: man who attempted to rape Eiri in order to "heal him psychologically"]]. He goes from StepfordSmiler to an AxCrazy {{Yandere}} in just a few short panels. Afterward? He's smiling again and brushing his rampage off like it was nothing.
* CrazyJealousGuy
* {{Crossdresser}}: Dons a nurse costume while taking care of a sick and not very cooperative Yuki in EX.
* DissonantSerenity: And if it breaks, [[{{yandere}} well…]]
* ItsAllMyFault: Two words: New York.
* ManipulativeBastard
* MyGodWhatHaveIDone [[spoiler: When a ''pregnant'' Mika gets sick due to stress and has to be hospitalized.]]
** To really put it into perspective [[spoiler: Tohma was so wrapped up in his business with Yuki that he ''neglected his pregnant wife'', who just happens to be Yuki's older sister. The stress of worrying about Yuki, and the lengths that Tohma would go to in order to do what he perceived to be in Yuki's best interests--including ''threatening Shuichi's life''--put Mika in the hospital. At least Tohma toned it down a bit when he realized he could lose his wife and child if he kept up his antics.]]
* OlderThanTheyLook
* PayEvilUntoEvil: The way he deals with [[AssholeVictim Taki]].
* RecordProducer
* StepfordSmiler: And when he isn't smiling? [[{{Yandere}} Be afraid]].
* TheAtoner: Only in regards to Eiri. Otherwise, he doesn't give a crap, generally.
* WhiteHairBlackHeart: Tohma who, while [[StepfordSmiler initially appearing to be an amiable person]], is shown to have a ruthless streak when his brother-in-law's safety or health is threatened.
* {{Yandere}}: At one point attempts to go after [[spoiler: Yoshiki dressed up as her brother]] ''with an axe'' for giving Yuki trauma. Sakano manages to hold him back, but the way Tohma looks in that panel is probably one of the most terrifying images in the entire manga.

!'''Ryuichi Sakuma'''
[[quoteright:250:http://static.tvtropes.org/pmwiki/pub/images/Ryuichi_5886.png]]
->'''Voiced by:''' Creator/KappeiYamaguchi (Japanese), Kenneth Robert Marlo (English)

* BareYourMidriff: The stage outfit he wears in the anime.
* BunnyEarsLawyer: In the manga.
* GeniusDitz: In the anime.
* HellBentForLeather
* {{Keet}}
* ManChild: Requires a keeper at all times and carries a stuffed bunny with him everywhere.
* ObfuscatingStupidity: In the manga, at least, his ManChild tendencies are hinted to be more deliberate than they seem at first glance.
* OlderThanTheyLook
* VerbalTic: Na no da!

!'''Noriko Ukai'''
->'''Voiced by:''' Creator/HarunaIkezawa (Japanese), MeganHollingshead (English)

* CoolBigSis: To Shuichi, sometimes.
* HappilyMarried: [[spoiler: To Tetsuya Ukai.]]
* MayDecemberRomance: [[spoiler: With aforementioned Tetsuya Ukai, a much older university professor.]]
* MegaTwintails
* OlderThanTheyLook
* TeamMom: Both for Nittle Grasper and for Bad Luck when she was working with them.

[[folder: Uesugi Clan]]
!'''Eiri Yuki'''
->'''Voiced by:''' Creator/KazuhikoInoue (Japanese), Rome Elliot (English)

--> ''(to Shuichi) "Because I'm a good guy, I have one more piece of advice. If you don't want to kill yourself, you should probably stay away from Mercedes [=SLEs=], and SAAB Cabriolets. Because if you get in front of me again, I'll hit you and then back up over you for good measure."''
[[quoteright:250:http://static.tvtropes.org/pmwiki/pub/images/Yuki_Eiri_5324.jpg]]

* ArmouredClosetGay: A nonviolent example. His early rebuffing of Shuichi is shades of this.
* ArrangedMarriage: [[spoiler:Although he and Ayaka never actually get married.]]
* BastardBoyfriend: Milder example. Sometimes a BespectacledBastardBoyfriend as well.
* BiTheWay: YMMV on whether he he’s actually attracted to women or just that deeply closeted, since the only people he has actual romantic feelings for are Shuichi and [[spoiler: Yuki Kitazawa]].
* BrokenBird
* BrutalHonesty: Tells Shuichi he's going to try to be more honest about how he feels, then follows with:
-->''It's inconvenient not to have a hole to fuck when I get in the mood.''
* TheCasanova: Before he meets Shuchi, his love life consists of one night stands and meaningless fuck buddies.
* ClosetKey: For both Shuichi and Tohma.
* DarkAndTroubledPast
* DeadpanSnarker
* DontYouDarePityMe
* DoubleStandard
* HaveIMentionedIAmHeterosexualToday: At least in the beginning.
* [[spoiler:InterruptedSuicide]]
* ManipulativeBastard
* PenName: His last name is really Uesugi, like his siblings. He took “Yuki” as his PenName as a form of atonement for [[spoiler: murdering Yuki Kitazawa]].
* PerpetualFrowner
* PetTheDog
* [[spoiler:RapeAsBackstory]]
* {{Seme}}
* SmokingIsCool
* TheStoic
** StoicWoobie
* SugarAndIcePersonality
* TallDarkAndSnarky
* UsedToBeASweetKid

!'''Tatsuha Uesugi'''
->'''Voiced by:''' Creator/HideoIshikawa (Japanese), JasonGriffith (English)

* AnnoyingYoungerSibling: To both of his siblings, though he causes significantly more grief for Yuki than Mika.
* DepravedBisexual: Played for laughs.
* PaletteSwap: He is nearly identical to his brother, but with tan skin and darker hair and eyes. So much so that Shuichi mistakes him for Yuki not once, but ''twice''.
* StalkerWithACrush: To Ryuuichi.

!'''Mika Seguchi'''
->'''Voiced by:''' Creator/HiromiTsuru (Japanese), Angora Deb (English)

* [[KnightTemplarBigBrother Knight Templar Big Sister]]

[[/folder]]

[[folder: Ask]]
!'''Taki Aizawa'''
->'''Voiced by:''' Creator/ShinichiroMiki (Japanese), Tim Breese (English)

* ArmouredClosetGay: When he’s telling Shuichi how disgusting and unnatural his relationship with Yuki is, it becomes pretty obvious that no small part of his rage and irrational hatred towards Shuichi is a result of his own self-loathing and repression.
* AssholeVictim: It’s hard to feel much sympathy for him when [[spoiler: Tohma has him run over by a car]].
* DrivenByEnvy: Becomes obsessed with destroying Shuichi, because he believes Bad Luck is being favored over Ask by NG and Tohma.
* IrrationalHatred: For Shuichi.
* ItsAllAboutMe: Initially decides Shuichi is his rival because he wants 100% of [[RecordProducer Tohma’s]] and NG’s attention and can’t stand having to share it with Bad Luck. It spirals out of control from there.
* JerkAss
** JerkWithAHeartOfJerk
* LaserGuidedKarma: Courtesy of Tohma.
* SmugSnake: ''His official character profile'' describes him with such terms as "arrogant" and "has a tendency to smirk".
* UnknownRival: To Shuuichi.

!'''Ken-chan and Ma-kun'''

* EveryoneHasStandards: Ken-chan and Ma-kun are ok with Taki messing with Shuichi at first, but eventually kick Taki out of the band for being such a [[MoralEventHorizon horrible]] {{Jerkass}}.
* ThoseTwoGuys

[[/folder]]

[[folder: {{Eagleland}} Characters]]
!'''Mister K'''
->'''Voiced by:''' RyotaroOkiayu (Japanese), Brian Maillard (English)

* AxCrazy: PlayedForLaughs
* BunnyEarsLawyer
* DisguisedInDrag: As a HugeSchoolgirl [[MakesJustAsMuchSenseInContext on a date with Hiro]], in an effort to distract the {{Paparazzi}}.
* DoNotCallMePaul: He's "K" when he's working. He even tells his wife to only call him "K" when he's working.
* EagleLand: Pretty much the embodiment of the Japanese stereotype of Americans TurnedUpToEleven.
* GratuitousEnglish: His dialogue in general is full of random English words and phrases. There's also a rather long conversation between him and Judy that's entirely in, [[{{Engrish}} ostensibly]], English (originally; Tokyopop's translation, er, translated it).
* GunFu
* TheGunslinger
* HappilyMarried: [[spoiler: To Judy Winchester, an A-list movie star.]]
* OnlyKnownByTheirNickname: At first. See DoNotCallMePaul above. Only his wife and Reiji ever call him him by his full name.
* PhenotypeStereotype: Blonde, blue eyed, tall, and shoots at anything. Obviously American.
* SpellMyNameWithAnS: Tokyopop’s translation changed the spelling of his first name to [[spoiler: Claude]]. Murakami’s original spelling of his name ([[spoiler: Krawd]]), while [[{{Engrish}} questionable]], has a more obvious connection to his nickname. Needless to say, readers who had never seen the original text were left somewhat confused.
* TriggerHappy: His propensity to shoot anything for any reason is a defining personality trait.

!'''Yuki Kitazawa'''
->'''Voiced by:''' Toshikatsu Izaki (Japanese)

* AssholeVictim: He may be a victim of murder, but it's hard to feel sympathy because [[spoiler: Eiri killed in self-defense when he paid some guys to gang-rape him.]]
* ClosetKey: For [[spoiler: Eiri]].
* HotForStudent
* PosthumousCharacter
* {{Shotacon}}
* TheAlcoholic

!'''Yoshiki [[spoiler:Kitazawa]]'''

* ButNotTooForeign: Yoshiki is American, but of Japanese decent and generally lacks all the typical {{Eagleland}} attributes shared by the other American characters.
* CloudCuckooLander
* DrivesLikeCrazy
* EveryoneHasStandards: Yoshiki can't bring herself to hate Yuki [[spoiler: for murdering her older brother]] because she recognizes her brother's actions as having crossed the MoralEventHorizon.
* GenderBlenderName: Retains her masculine birth name despite identifying as a woman.
* ParentalSubstitute: For Riku.
* SweetPollyOliver: Briefly, when she dresses up as her dead brother as part of a plan to help Yuki get over him.
* TransEqualsGay: Mostly due to Murakami being Japanese and Japanese culture having a poor grasp on gender identity issues. She uses the term ''okama'' to describe herself at one point and Tokyopop chose to translate this as "gay". The terminology used by both Yoshiki herself and the characters to describe her is especially jarring since Yoshiki behaves more or less like a straight woman and not like a gay man at all.
* {{Transsexual}}
* {{Transvestite}}: Yoshiki started dressing like a girl to get more attention, which somehow evolved into becoming actually transgender.

!'''Reiji aka Rage'''
->'''Voiced by:''' MikiNagasawa

* BerserkButton: Don't say she's just a chick!
* ButNotTooForeign: She's as American as K is, but ethnically Japanese and speaks the language the fluently. She still has the designated {{Eagleland}} trait of being AxCrazy, but is otherwise doesn't come off as foreign the same way that K does.
* CallingTheOldManOut: When she quits working for XMR so she can follow Shuichi to Japan, she tells her dad (who is also the label boss) how she really feels.
* DoubleStandardAbuseFemaleOnMale: Her treatment of Shuichi is this.
* FagHag: She has feelings for Shuichi, but also gets [[GuyOnGuyIsHot turned on by guy-on-guy]]...
* GenderBlenderName: Reiji is fairly common Japanese name. For boys.
* HotBlooded
* {{Meganekko}}: Something of a deliberate subversion of the usual personality associated with this trope. Murakami does state in her notes that she gave Reiji glasses because of RuleOfSexy.
* ObliviousToLove: Poor [[IgnoredEnamoredUnderling Bill]].
* PunnyName: Reiji is pronounced just like the English word Rage.
* StalkingIsFunnyIfItIsFemaleAfterMale: She follows Shuichi all the way from [[BigApplesauce New York]] to Japan and strong-arms her way into becoming his manager. And it’s ''hilarious''.
* {{Tsundere}}
* YaoiFangirl

!'''Ark'''

* BadassInANiceSuit
* BeingPersonalIsntProfessional
* ConsummateProfessional
* CorporateSamurai
* SharpDressedMan

!'''Riku [[spoiler: Kitakazwa]]'''

* CheerfulChild
* ParentalAbandonment
* TagalongKid

[[/folder]]

[[folder: Everyone else]]
!'''Sakano'''

* ButtMonkey
* TheChick: In the Bad Luck + K and Sakano FiveManBand configuration, he is most definitely this.
* IgnoredEnamoredUnderling: For Tohma.
* NoNameGiven: Only known by his surname. Not even Murakami knows what his given name is.
* OnlyOneName: Again, only known as "Sakano".
* SubordinateExcuse: Why else would he keep working for Tohma?

!'''Ayaka Usami'''
->'''Voiced by:''' Creator/RieTanaka (Japanese), Creator/RachaelLillis (English)

* ArrangedMarriage: [[spoiler: To Yuki. She calls it off later.]]
* HimeCut

* RavenHairIvorySkin
* {{Ojou}}

!'''Maiko Shindou'''

* AdaptedOut: Of both anime adaptations.
* AnnoyingYoungerSibling: To Shuichi.
* OutOfFocus: In the manga. She features prominently in the beginning, while Shuichi and Hiro are still in high school, but disappears almost entirely once he graduates and the setting changes.
