!!The Main Trio

->'''Voiced by:''' Creator/AyakoKawasumi (JP), Creator/KariWahlgren (EN), Creator/MarianaOrtiz (LA)

The protagonist of the story, in search of the "Samurai who Smells of Sunflowers". She travels across Japan with Mugen and Jin as her unlikely bodyguards. [[PluckyGirl Plucky]] and determined, she'll stop at nothing to find this mysterious samurai.

* ACupAngst: At least once verbally express jealousy over another more endowed woman. She's also delighted in ep. 5 when the Ukioe artist draw her with large breasts.
%%* {{Adorkable}}:
* AllLovingHero: Not a mean bone in her body, and due to her actions she saved both main's lives and an innumerable number of side characters.
* ArentYouGoingToRavishMe: In one episode, Fuu believes she is to be the "prize" in a duel between two brothers battling to succeed their father's dojo (they had both commented on how absolutely cute something was while looking in her direction). When the duel is over, the two brothers approach Fuu as though they're going to glomp her, only to become preoccupied with her flying squirrel. Fuu is pissed.
* AwesomeAnachronisticApparel: As shown during Episode 1's coin toss, she sports decidedly 20th-century [[ArcSymbol sunflower-patterened]] nail art.
* BadassAdorable: Despite her cute looks, this {{Adorkable}} girl managed to continue eating in the Edo eating contest ''without stopping''!
* BelligerentSexualTension: Has a ''ridiculous'' amount with Mugen, so much so that more than a few viewers were surprised when they did not receive a RelationshipUpgrade in the final episodes.
* BerserkButton: While not driving her into a murderous rage, she gets pissed whenever Mugen calls her ugly.
* BigEater: Interestingly, she fits both the "surprisingly skinny" and "fat" versions of the trope, as she's normally pretty lanky, but will temporarily swell up and get a BalloonBelly after some particularly serious eating.
--> '''Mugen''': You're some kind of low-grade monster.
** [[JustifiedTrope She is]] a teenager, a time when metabolisms are at their highest.
** Used to hilarious extremes in one episode, when after eating a huge meal, after which she looks like she's put on 200 kg, she is seen by a set of [[{{Mooks}} guards]] with Jin and Mugen when they've just gotten themselves into trouble (again). The guards run into her again after she's slimmed down and ask her:
--> Excuse me, miss, have you seen a really fat girl around your age?
* BodyguardCrush: Possibly on Jin, Mugen, or both. While most interpret her as being closest to Mugen, she's more openly affectionate with Jin (as they're both of samurai families, they have much more in common).
%%* TheChick
* ClingyJealousGirl: She tends to get mad when Mugen shows interest in other girls.
* CurtainsMatchTheWindow
* CuteClumsyGirl
* DamselInDistress: A fairly justified version, since Edo period Japan was very dangerous place to travel around in, especially for a normal teenage girl. It's why she wanted Mugen and Jin, who have pasts which justify their combat prowess, to travel with her in the first place.
* DudeMagnet: Despite being told she lacks sex appeal, she manages to attract a lot of male attention. Examples include Moronobu, Sosuke, and Nagamitsu among others. However she seems to believe she only attracts weirdos.
* FlowerMotifs: Various vegetables and plants in the opening, but she has a special connection with sunflowers.
* GagBoobs: In the first episode, [[FakeBoobs she hides some bombs in her dress]] and runs through town with them [[{{Gainaxing}} bouncing to and fro]].
* GreenEyedMonster: She's angry whenever Jin or Mugen visit other woman.
** Interesting to note though that whenever Jin gets interested in another woman she gets seriously concerned and worried about him, while when Mugen gets interested in another woman she just gets furiously jealous.
* HatesBeingAlone: She hates being separated from either Mugen and Jin.
* TheHeart: She keeps Mugen and Jin from killing each other, and takes it hard whenever they try to leave.
* HeavyVoice: Has one on the occasions that she gorges herself to obesity.
* UsefulNotes/JapaneseChristian: [[spoiler:The daughter of Saizo Kazumi, leader of Christianity in Japan.]]
%%* TheKirk
* LikeBrotherAndSister: Seems to have this relationship with Jin.
* MementoMacGuffin: The skull charm on her knife's sheath. [[spoiler:It's a hint to her father's past, but she doesn't learn this until near the end of the series]].
* NeutralFemale: Not quite. She's physically weak and small, and probably should stay out of fights, but she intercedes on more then one occasion. Personality-wise, she is a very strong, determined person and is by no means completely helpless when she's stuck in a tight spot. ''Hellhounds for Hire'' comes to mind.
* NiceGirl: While she may get frustrated by her companions antics, she's ultimately a very considerate person who can even sympathize with those who kidnap her.
* PluckyGirl: She runs off with two guys she's never met, one of dubious morality, saves their asses from the government, to find some guy whose face she doesn't remember. Does she give up? No. Does she give in? Hell no! Face it, Fuu is stronger willed then either Mugen or Jin. Or just plain insane.
** For a specific example, in one episode a thug tries to threaten her with a knife and tells her if she screams, he'll kill her. She goes ahead and screams before he has time to actually put the knife in a threatening position.
* TheProtagonist: While Mugen and Jin are more active due to their fighting skills, the plot is still primarily about Fuu's quest to find the Sunflower Samurai.
* ShipTease: In the anime and manga with Mugen which WordOfGod backs up.
* SpellMyNameWithAnS: A single example--the ''Impression'' soundtrack CD has a song called "Who's Theme".
* SmallNameBigEgo: She thinks the men are lining up to ravish her. She's usually wrong.
* SunnySunflowerDisposition: She's a warm and brave girl who is associated with flowers.

->'''Voiced by:''' Creator/KazuyaNakai (JP), Creator/SteveBlum (EN), Creator/IrwinDaayan (LA)

A violent, [[HotBlooded incredibly brash]] vagrant who [[BloodKnight always seeks out a fight]]. His escapades lead him to a duel with [[WorthyOpponent Jin]], then the two swordsmen accompany Fuu in search of the Sunflower Samurai.

%%* AfroAsskicker
* AmazonChaser: Mugen usually prefers strong women to the more [[YamatoNadeshiko quiet]] ones that he meets. The women don't even necessarily need to be fighters--they just have to have a strong will and/or confidence to catch his eye.
* AnimalMotifs: Is associated with Roosters in the opening, possibly because of his arrogant, cocky nature.
* AntiHero: Seems to be a Type V at first, but acquires some traces of a Type IV. He's a foul-mouthed BloodKnight who will frequently abandon his companions for the sake of a good fight, and cares little for his promise to Fuu, instead trying to fulfil his promise to kill Jin. But he also teams up with the latter numerous times, rescues Fuu even if it inconveniences him, scorns at the idea of villainy, and in the end, [[spoiler:honors his companions as true friends]].
* AwesomenessByAnalysis: He learned how to use energy to attack his opponent after having it used once against him, being told what his opponent had done and one month of (mostly irrelevant) training.
* BalloonBelly: Tends to happen when he seriously overeats.
* BerserkButton: Not that it takes much to piss him off, but Mugen ''really'' can't stand when Japanese people mistreat foreigners like the Dutchman (and the Russian from the manga). Obviously, it hits a little close to home for him.
* BloodKnight: In one episode, he tries to start a fight with Fuu's pet squirrel.
** In fact, the only time he ever turns away from a fight is when [[spoiler:he goes to rescue Fuu from where she's being held on that island]]. And that said, he did so reluctantly (he was desperately out-classed and if he'd stayed Kariya would've killed him) and he knew he was running towards another fight.
* BookDumb: Semi-literate at best and terrible with numbers. Interestingly, he takes learning how to write rather enthusiastically.
* ButForMeItWasTuesday: Cut off one guy's arm and didn't care enough to remember. When his victim tracked him down with a GiantMook and an elaborate murder plot and promised to make him pay for his crimes, all he got in return was a blank look.
* CharacterDevelopment: He slowly comes to care about someone other than himself, most notably Fuu. By the end of the anime, he's also learned to use his head a little bit more in fights. He also finally makes peace with his [[BloodKnight desire to start fights with anyone and everyone just because.]] [[spoiler: At the end of the series, he admits that he considers Jin to be a friend and has no desire to fight him anymore.]]
* ChickMagnet: Suprisingly, chicks seem drawn to him. Moreso than Jin, in fact, who's supposed to be better looking.
* CombatPragmatist: Mugen doesn't know the meaning of fair play.
* CruelMercy: [[spoiler:Kohza betrays him so that she will not be alone, something she's terrified of. He kills everyone in the old crew who betrayed him and then just ignores her, even when she begs him to kill her.]] Needless to say, it says a lot when ''Mugen''--a guy who has few qualms about killing -- deems someone NotWorthKilling.
* DanceBattler: Break dancing to be specific, he even has steel plates on the soles of his sandals. His style is also often compared to capoeira, a Brazilian martial art that combines elements of dance, acrobatics and music, and could plausibly have been learned from a passing Brazilian sailor. (Or invented on the spot.)
* {{Determinator}}: The man [[spoiler:''dies'' more than once during the course of the series, and comes back to life]] through sheer determination!
* DidYouJustFlipOffCthulhu[=/=]RageAgainstTheHeavens: [[spoiler:When he dies the first two times, he tells the [[TheGrimReaper Futuchi reapers]] that [[ItIsNotYourTime it's not his time yet]] and uses the former trope by telling them to take their job and shove it by returning him to the living world. When he dies the third and final time (in the last episode, no less), this turns into the latter trope by demanding that he be sent back to the living world at once. Once again, it's Mugen 3, Death 0, as our hero reigns victorious.]]
* HiddenWeapons: [[spoiler:He has a dagger hidden in the end of his sword's scabbard. He only considers using it as a last resort, and only does so twice over the course of the whole series.]]
* ImplacableMan: He's extraordinarily resilient and has recovered from injuries that were all but explicitly lethal.
* ImprobableAge: Although no one's quite sure of his age, Mugen is generally thought to be no older than twenty, which is pretty young for a man of his abilities and experiences.
* InformedFlaw: His ugliness. In some episodes his face is legitimately loathsome, but in others he's just ruggedly handsome. He pretty consistently looks as though he's made completely out of elbows.
* InformedLoner: For a guy who will insist, with sharp objects if pressed, that he works for and with no one but himself, he encounters old foes and friends nearly as frequently as Jin. And he is still getting dragged around behind Jin and Fuu.
* IWorkAlone:
--> '''Mugen:''' I don't believe in anyone, but me, and what ''I'' can do.
--> '''Mugen:''' I don't work for no one, but me.
--> '''Mugen:''' Now I lived my whole life without takin' help from nobody, and I'd be damned if I let you guys help me into my grave.
** Part of his character development is the realization that [[YouAreNotAlone he's not alone]] [[TrueCompanions after all]].
* JerkWithAHeartOfGold: Moreso later on - and Mugen may threaten murder against anyone who implies it.
* LogicalWeakness: Being untrained in formal combat, Mugen relies on his erratic movements and raw strength to beat his opponents. As such, a fighter who is StrongAndSkilled will give him a tough time.
%%* LonerTurnedFriend
* MadeOfIron: He's been been in close proximity to massive explosions, had his belly slashed open, was shot in the back with a musket ball, tortured, mauled by a psycho with a scythe, and [[spoiler:even ''died'' on more than one occasion]]. And each time he recovered completely within a short space of time with no apparent lasting effects.
%%* TheMcCoy
* MixAndMatchWeapon: His katana's crossguard looks like a sai's prongs. In fact he uses it to snap a blade during a fight.
* NeverLearnedToRead: Although an early episode shows him reading, or at least recognizing, the words for certain foods from a menu.
* NobleMaleRoguishMale: The Roguish Male to Jin's Noble Male.
* NoSocialSkills: Mostly because he doesn't care who he offends and is pretty much just a rude thug at the start of the story.
* OnlyMostlyDead: [[spoiler: Another possible (albeit more mundane) explanation for how he seems to keep coming back.]]
%%* PermaStubble
* PerpetualFrowner: Seems to have attained a state of unending rage and spite at all things and people in general.
* RebelliousSpirit: If someone pushes Mugen, he will always push back. He doesn't need a reason.
* RedOniBlueOni: Red One to Jin's Blue Oni. They even have the [[ColorCodedForYourConvenience clothing choices to match]].
* ResurrectiveImmortality: Possibly. It's certainly invoked with the SpiritWorld imagery whenever he dies, but it's not impossible that the resurrections are just Mugen's HeroicSecondWind and the visions of the spirits reviving him are just symbolic and/or hallucinations.
* TheRival: To Jin.
%%* SatisfiedStreetRat
* SwordDrag: Does this in ''Hellhounds for Hire'' when charging at Jin. Totally for the RuleOfCool, by the way.
%%* TallDarkAndSnarky
* TattooedCrook: The blue rings tattooed around his wrists are a historical Japanese method for identifying convicts.
* TechnicianVersusPerformer: The performer to Jin's technician.
* TokenEvilTeammate: Though he's far from evil, he ''is'' an asshole with little regard for human life, a hair-trigger temper and enough {{Berserk Button}}s to give TheHulk a run for his money.
* TheUnfettered: He gives his all to every single thing he does.
* UnskilledButStrong: Being a self trained swordsman, Mugen uses eratic movements in fights with opponents instead of actual technique. Majority of the time it works to his favor. When facing opponents like Ukon and Sara, Mugen found himself outclassed and forced to actually use his head. [[spoiler: When facing Kairya, he's ''hopelessly'' outclassed and Jin convinces him to leave the fight.]]

->'''Voiced by:''' Ginpei Sato (JP), Creator/KirkThornton (EN), Christian Strempler (LA)

A quiet, [[TheStoic stoic]] ronin who [[KnightErrant seeks a purpose and calling in life]]. After a duel with [[WorthyOpponent Mugen]], the two swordsmen accompany Fuu in search of the Sunflower Samurai.

* AnimalMotifs: Is associated with Carp, symbol of samurai values, but also other sea creatures in the opening. This creeps into the show itself through his interactions with Johnny.
* AttractiveBentGender: He's pretty enough to get into a brothel while disguised as a prospective prostitute, his height being the only unusual thing about "her".
* {{Bishonen}}: The most standard example of one in the show; he's even able to pass as a woman.
* BloodKnight:
** Although he doesn't go out of his way to start trouble, Jin never backs down from a fight.
** Subverted in his fight with Yukimaru, which is a major characterization point. Jin urges Yukimaru to withdraw, so that he will not have to put an end to the fight.
* BornInTheWrongCentury: According to Jin, there isn't any worthy lord to serve nowadays. The clan symbol on his kimono indicates he's descended from the Takedas or their close retainers. The Takeda clan was one of the Tokugawa clan's two main rivals prior to their securing the shogunate, but was exterminated in the power struggle. So Jin is literally a relic of a bygone family and era.
* CharacterDevelopment: Just like Mugen, Jin gains human connections during the series, so he finally has something he wants to protect.
* CombatCompliment: Both Inuyama and Kariya praise his skill as a swordsman.
* CombatPragmatist: Over time, Jin takes the Firefly Samurai's advice to heart and starts to use his surroundings to his advantage.
* TheComicallySerious: After being...entertained by at least ''two'' prostitutes, he gets up and takes out an attacking group of five men in two slices. Then doubles over. "My back!"
** "I have heartburn..."
* CovertPervert: Jin is perhaps almost as interested in women as Mugen is, he's just a little more quiet about it.
* DangerousForbiddenTechnique: [[spoiler:He learns about a technique that allows an opening for the opponent to strike, but the opponent is also vulnerable for a fatal blow. The move is supposed to be only used as a last resort, as it's effectively a [[TakingYouWithMe suicidal move]], but Jin manages to survives as he uses this technique to defeat Kariya.]]
* DeadpanSnarker: It's practically his default expression. He never hesitates to call Mugen out on his foolishness.
* {{Determinator}}: Gets a sword through his stomach and keeps going. Able to fight at peak level after being tortured for a whole day. Also falls off bridges a lot. A LOT. You start to wonder if he has gills.
* DisguisedInDrag: In Episode 3, to get into a brothel.
* DrivenToSuicide: Maybe. In Episode 15, when faced with one of his fellow students from his old dojo who has come to kill him (during a time right after Fuu broke the group up after a fight with Mugen), Jin only half heartedly fights him for a little bit before turning around and jumping off the waterfall behind him. Next time we see him though, he is perfectly fine; and when the other guy comes back, he even wonders if Jin was just trying to run away.
* EeriePaleSkinnedBrunette: Especially since he's so quiet.
* TheFettered: Jin refuses to follow the modern way of the samurai and aristocracy on principle and is always ready to help people in distress, even if he can be rude about it.
* GoodIsNotNice: Not as bad as usual cases since most of it's more just his serious personality. As a card-carrying samurai [[spoiler:he saves a DamselInDistress from a life of prostitution (and it's heavily implied he'll marry her after her period of isolation ends)]], will not serve the currently corrupt Government in return for wealth and respect, and refuses to use force if he doesn't have to. However, he is not exactly friendly, starts off with a small superiority complex, doesn't mind sex with prostitutes even ''after'' he rescues a severely traumatized one, and in the first episode he saves a peasant from the the corrupt lord that was going to have the peasant beaten or killed for not giving the lord a sufficient bribe, but he takes the peasant's cash too. Of course, the peasant is probably happy to not be on the wrong end of the katana. Then again, saving said peasant proved useful as he later gives Fuu the pipe needed to start the fireworks that would save Mugen and Jin from their executions.
* HonorBeforeReason: See TheLastDJ below.
* KnightErrant: Prior to the series. He [[WalkingTheEarth wandered around Japan]] searching for a purpose until Fuu roped him as her bodyguard.
* KnightInSourArmor: He knows damn well that it doesn't pay to be good or honorable in the world he was born into. But he just can't help himself from doing the right thing.
* TheLancer: Jin is ''much'' less likely to instigate an episode's events than Mugen and Fuu are, and rarely involves them in his conflicts.
* TheLastDJ: He could be a famous and wealthy warrior, but first he'd have to find a daimyo he didn't loathe.
** [[spoiler:Furthermore, Jin's old master told Jin about the shogunate's plan to turn their school into a corps of assassins for the government, and Jin vehemently protested on principle. For this his master was ordered to kill him, but Jin was the winner of that fight. He could probably clear his name in a second and do serious damage to the government by telling the truth. He'd also dishonor the name of his master and his school, so he goes WalkingTheEarth instead.]]
* LethalChef: In "Gamblers and Gallantry", Jin mans a grilled eel stand alongside a woman he ran into earlier in the episode. After the dinner rush, he agrees to cook her an eel. Her reaction? "...Wow. Your cooking is really quite amazing. I'm pretty sure this the worst thing I've ever eaten! But I suppose that's a talent in and of itself..."
* LikeBrotherAndSister: Seems to have this relationship with Fuu.
%%* LonerTurnedFriend
%%* LongHairedPrettyBoy
* MadeOfIron: Not to the extent of Mugen but the few times he gets severely beaten he just gets back up.
%%* {{Megane}}
* MistakenForGay: Both Mugen and the "Firefly Assassin" from episode two assume on first impressions that he walks down the left side of the street. There are some suggestions that Jin's old school friend Yukimaru was [[LoverAndBeloved more like an old flame]]. On the other hand, he seems perfectly willing to sleep with women when the opportunity arises (to Mugen's vocal relief) and he genuinely falls for [[spoiler:Shino]].
** Worth noting: In the Edo Period, particularly for men of Jin's socioeconomic status, [[EveryoneIsBi bisexuality was the default assumption]]. Samurai men were expected -- even required -- to show interest in women but it was perfectly acceptable to bed another warrior or a hot kabuki actor as well.
* MrFanservice: Very much so, especially when you factor in his {{Shirtless Scene}}s.
* NobleMaleRoguishMale: The Noble Male to Mugen's Roguish Male.
* NotSoDifferent: With Mugen, both highly trained fighters who don't really enjoy themselves (except in combat) and put a lot of emphasis on martial prowess. Neither experienced love in their lives until they met up with each other ([[MyFriendsAndZoidberg and Fuu]]). Yes, that was intentionally [[HoYay hoyaytastic]].
** Jin's swordfighting technique, "The Sword of No Abiding Mind", teaches precognitive or instinctual method of fighting, with the aim of being unreadable by your opponent. Mugen just plain doesn't think and wings everything he does. These two essentially use the same fighting style, only approached from the different places.
* TheOnlyOneAllowedToDefeatYou: To Mugen.
* PerpetualFrowner: The number of times he gives a sincere smile throughout the series can be counted on one hand.
* PurelyAestheticGlasses: Anachronistic ones, at that. [[spoiler:He stops wearing them after they break in the final episode.]]
* TheQuietOne: In contrast to Mugen and Fuu, who talk nonstop about their adventures and surroundings, Jin remains silent most of the time, emphasizing his character as the calm, serious one in the group.
* RavenHairIvorySkin: Raised and trained indoors, in contrast to deeply suntanned pirate-wanderer Mugen.
* RedOniBlueOni: Blue to Mugen's red.
%%* {{Ronin}}
* SacrificedBasicSkillForAwesomeTraining: Trained from childhood in a high-level and super purist dojo, by age 20 he's a fearsome, near-unbeatable kenjutsu prodigy who can't cook, catch fish, hold a conversation (especially with women), or drink more than two shots of sake without falling asleep. He makes a little progress towards (metaphorically) tying his own shoelaces over the course of the series.
* SamuraiPonytail: Though a ronin, he keeps up the proper appearances.
* ShirtlessScene: With torture scenes, hot springs and good old fashioned sword fights, he gets a couple.
* ShroudedInMyth: If you heard the stories being spread about "The Thousand Man Killer" and his exploits, you'd be pretty shocked to find that the guy behind the rumors is the slightly fey broke dude facepalming at his travelling companions.
* SkilledButNaive: One of his early opponents, Inuyaka, notes that while he's a very skilled swordsman, he hasn't had enough outside experience to fight him in an unfamiliar environment, as he's spent his entire life training in a dojo.
* SlipknotPonytail: [[spoiler:His hair lets loose when he comes back to stop Kariya.]]
* TheSpock: He [[StrawVulcan rarely shows emotion]] and is dispassionate about everything.
* StoicSpectacles: He's quite fond of them too.
* TheStoic: Virtually nothing causes him to lose his cool... except being mocked for his lack of fishing skill.
* StrongAndSkilled: He's just as dangerous as Mugen in a fight but is more skilled than him.
* SurpassedTheTeacher: Jin proves he's done so by [[spoiler:foiling his master's attack -- leaving him technically master of the discipline after Mariya's death.]]
%%* TallDarkAndHandsome
%%* TallDarkAndSnarky
* TechnicianVersusPerformer: The technician to Mugen's performer.
* TranquilFury: You can practically feel the temperature around him drop when he's getting angry, but he won't make a sound.

* DentedIron: Implied to have once been a skilled warrior [[spoiler:but when he shows up in the series, he's too ill to even stand, let alone put up a fight against Kagetoki]]
* FlowerMotifs: Um,[[ExactlyWhatItSaysOnTheTin guess which one.]] Interestingly, sunflowers were originally foreign to the land, brought to Japan from the West, [[spoiler: much like Christianity, the religion he practiced.]]
* IllMan: [[spoiler: By the time Fuu finds him, he's on his deathbed.]]
* UsefulNotes/JapaneseChristian: [[spoiler:He is one and worked to save them from persecution. Keeping Fuu and her mother safe was the reason he left.]]

[[folder: Mugen's Run]]

Mugen's prize beetle. [[DepartmentOfRedundancyDepartment Rodriguez is her name]].
%%* BloodKnight: She's a beetle.
%%* CoolPet
* SlidingScaleOfAnthropomorphism: She's a beetle.
* StrongAnts: They took this trope, tied it onto a rock, and made Rodriguez drag it almost beyond its logical extreme, although this is TruthInTelevision if somewhat exaggerated.
* TrainingFromHell: She spends much of the episode dragging a rock around.

->'''Voiced by:''' Creator/KiyoyukiYanada (JP), Kim Strauss (EN)

Wanted criminal, pirate captain, former cohort of Mugen. Arguably the nastiest human being to ever appear on the show.
%%* BigBrotherBully: To Kozha.
* ChronicBackstabbingDisorder: Betrays Mugen twice, and betrays his entire crew along with him the second time. It's not as extreme as some examples, but one still wonders how Mukuro ever manages to get a crew together.
* CurbStompBattle: On the receiving end of one from Jin after the latter finds out about his betrayal of Mugen.
* EtTuBrute: When he realizes Kozha has betrayed him.
* EvilCounterpart: To Mugen. He demonstrates how Mugen would have turned out if he'd embraced his hatred of the world, instead of letting it distill into mere apathy.
* EvilFormerFriend: At some point in the past his and Mugen's relationship was, if not friendly, at least less contentious than it is now. That died when Mukuro left Mugen to die the first time, and after his actions in "Misguided Miscreants" Mugen wants to kill him.
* {{Greed}}: Motivated only by money.
* TheGunslinger: Carries a ''very'' anachronistic six-shooter.
* ImproperlyPlacedFirearms: Could Mukuro have gotten a handgun in Edo era Japan? Absolutely. Could he have gotten the Wild West style six shooter he's carrying? No.
* IncestSubtext: Although never outright stated, it's shown that Mukuro has been abusive and controlling of Kohza in the past, and the way he strokes her face is... questionable.
* LackOfEmpathy: Displays no empathy or sympathy towards his crew, his sister, or his former friend Mugen.
* {{Pirate}}: Makes his living as one, operating around the coast.
%%* PragmaticVillainy
* SmugSnake: Very convinced of his own brilliance.
* RevolversAreJustBetter: Even when having one violates the timeline.
* TheUnfought: To Mugen anyway. Jin is the one who kills him.

->'''Voiced by:''' Creator/AiMaeda (JP), Creator/StephanieSheh (EN), Mayra Arellano (LA)

Mukuro's perpetually gloomy younger sister. She has a fondness for Mugen that dates back to their days of piracy, though the feeling is not quite mutual. Kohza isn't so much in love with Mugen as she is attached to him. This stems from her chronic dependency.
* AllLoveIsUnrequited: She seems to have genuine feelings for Mugen, which is both seen in the past and present. He’s probably the only person she actually did care about.
%%* AntiVillain
%%* BestServedCold
%%* BitchInSheepsClothing
%%* ChronicBackstabbingDisorder
* TheEeyore: Perpetually gloomy and depressive.
* FateWorseThanDeath: [[spoiler:Having grown tired of Kohza's manipulation, Mugen leaves her to survive alone despite her desperate pleas for him to kill her. Note that she has a pathological fear of being left alone.]]
* HatesBeingAlone: She simply can't bear to be alone. [[spoiler:At the end, Mugen doesn't kill her because he knows that for her having to live alone is worse than death.]]
* ManipulativeBitch: [[spoiler: Knowing Mugen would be betrayed again, she acted sympathetic to get Jin to kill Mukuro, leaving her and her boyfriend free to take the money and run.]]
%%* OhCrap
* {{Revenge}}: [[spoiler:On Mukuro. Not for Mugen, but her mother.]]
* YouKilledMyMother: Mukuro killed her mother and she takes her revenge for her.

->'''Voiced by:''' Creator/NorikoHidaka (JP), Creator/MichelleRuff (EN), Patricia Hannidez (LA)

A skilled ninja working as a prostitute in covert to break up a criminal operation counterfeiting coins. She is the daughter of Imano Jinpachi, a member of the Shogunate guard staff. She is purchased by Mugen after winning a rock-paper-scissor game with Jin to see who will stay with her. While Mugen is preparing himself for Yatsuha, she overhears a conversation about the counterfeiting through a wall. After failing multiple attempts to subdue Mugen, who thinks her actions are foreplay, Yatsuha resorts to tricking Mugen into helping her stop the counterfeiting operation by promising him a night of sex.
* ActionGirl: Not quite Mugen's equal in straight-up fight, and nowhere near Sara's level. But she and Mugen single-handedly took out an entire counterfeit coin operation.
* AllAmazonsWantHercules: She states she intends to marry Mugen when they meet again. Considering Mugen's taste in women, that may very well happen.
%%* BoisterousBruiser
* DoesNotLikeShoes: Goes completely barefoot when she goes into action mode
* MotivationalLie: Convinces Mugen to help her by using one.
%%* {{Ninja}}

!!Pantu/Grim Reapers/Ancestor spirits

->'''Voiced by:''' Creator/KeiichiNanba (JP), Creator/DerekStephenPrince (EN)

The youngest of the brothers. His and his brothers' lives were ruined by Mukuro and Mugen during a pirate raid on a sugar shipment. He is the least stable of the three and prone to violent fits of uncontrollable urges to kill. He carries a bisento short enough for him to wield and whines or shrieks wildly whenever he opens his mouth.
* AxCrazy: Literally ''twitches'' while trying to contain his bloodlust. That should say it all.
* CombatPragmatist: Ambushes Mugen on a small boat loaded with large barrels, knowing very well that Mugen will be unable to use his usual style in such a small area.
* DoubleWeapon: His other main weapon... well, it looks like two triangular-shaped blades on a ring-shaped handle.
* {{Gonk}}: The guy looks kinda like [[VideoGame/SamuraiShodown Genma Shiranui]] with a better skin, but that's the kindest thing you can say about him.
* PsychopathicManchild: Equally insane as his other two brothers, he's the most child-like of the gang.
* SharedUnusualTrait: The brothers all have pink sclera on their left eyes; it's arguably the only physical trait they share. It may be due to some degree of damage. Unlike Umanosuke, both Denkibou and Toube don't have to use any protection.
* WolverineClaws: Wears a single set on his left hand, though they're rather short.

->'''Voiced by:''' Creator/TakehitoKoyasu (JP), Creator/DougErholtz (EN), Héctor Reynoso (LA)

The middle of the brothers. He sports a hefty chonmage, wears an eye patch, and wields a spectacular weapon: a chain-sickle kusarigama with an incredibly long reach.
* AxCrazy: Like Denkibou, he's a seething, barely-contained cauldron of homicidal fury. Unlike Denkibou, he can sort of keep it under control... that is, until the eyepatch comes off. Once that happens, he becomes every bit as unhinged as the latter.
* TheBerserker: Not really blatant at first (well, compared to Denkibou) but much more clear later on in his battle against Mugen.
* EyepatchOfPower: Wears an eyepatch, but to protect his large, sensitive eye rather than cover a gaping hole.
* FauxAffablyEvil: The first true example is probably when he murders a random wanderer who just happened to be passing by when he didn't gave him the information he wanted to know. Information that he probably didn't have any way to know, to boot.
* TheHeavy: He's Mugen's biggest antagonist, and his actions drive the conflict for the final confrontation in the series. He's also one of Mugen's toughest opponents.
* HoistByHisOwnPetard: [[spoiler:Mugen uses his own scythe to behead him.]]
* KiAttacks: While it's unknown who taught him how to use them, it becomes obvious fairly quickly that his scythe is far stronger, and faster, than his frame would allow. Not to mention the impossible accuracy with which he uses it. See PersonOfMassDestruction.
* OffWithHisHead: He seemingly has a penchant for killing people this way using his scythe. This is also how he dies.
* PersonOfMassDestruction: Relatively so. He can demolish a house in a couple swings, and has destructive capabilities comparable to the more powerful bombs available.
* RapeIsASpecialKindOfEvil: He fondles Fuu, and while he never goes as far as raping her, the threat is on the table. He's mainly holding off so that he can finish the job in front of Mugen (or after Mugen dies with the knowledge of what's going to happen).
* RedEyesTakeWarning: Well eye in this case, he sports an eyepatch on his left eye due to losing an eyelid rendering him unable to blink. When it gets knocked off, his eye is red colored from the lack of water. Umanosuke also gets much crazier by this point in their fight.
* RevengeBeforeReason
* SharedUnusualTrait: The brothers all have pink sclera on their left eyes; it's arguably the only physical trait they share. It may be due to some degree of damage. Umanosuke is the only one of the brothers that has to use protection, but it's mostly due to his loss of the eyelid.
* SinisterScythe: An one hell of a scythe. It looks like a western-style long-handled scythe but the top half can detatch, turning in some sort of mutant kusarigama.

The eldest of the brothers. Like his brothers, he lives for revenge. Mugen severed his leg in the raid on the ship he was protecting, and since then he has never uttered a word and uses a wheelchair.
* AnArmAndALeg: Mugen severed his leg before the series.
* DumbStruck: Never spoke again after being injured by Mugen.
* EvilCripple: He's down a leg and, along with his brother's are the final villains Mugen has to fight in the series.
* FinalBoss: He serves as Mugen's final opponent. Even if he's just in a wheelchair, he's hellbent on taking Mugen down, [[TakingYouWithMe even if he goes with him]].
* GoOutWithASmile: Gives a wicked grin as he commits suicide via a bomb in his wheelchair, thinking it will kill Mugen too.
* TheQuietOne: He never speaks a word.
* SharedUnusualTrait: The brothers all have pink sclera on their left eyes; it's arguably the only physical trait they share. It might due to some degree of damage. Unlike Umanosuke, both Denkibou and Toube don't have to use any protection.

They risk their lives to put text where no brush has scribbled before. They are first seen brawling in the street over who's the real head of the gang.

!!Kariya Kagetoki
->'''Voiced by:''' Takayuki Sugou (JP), Creator/SteveKramer (EN), César Soto (LA)

An elite samurai working for the Shogunate known as the "Divine Hand" for his skill. Kariya has not drawn his sword in quite some time being that there hasn't been an opponent worthy of him in years, according to Goroujuu, a member of the Shogun's council who visits him. He determines that Mugen and Jin must be worthy adversaries, and brings himself out of retirement in order to face them. Although employed by the Shogunate, his true motives are to use the government to further his own needs since the age of the samurai is ending.

* BigBad: He's about the closest thing to a main antagonist in the series, given that he plays a major role in both Fuu and Jin's storylines. He's ordered to kill [[spoiler:the Sunflower Samurai]], and he was the one who ordered Mariya to kill Jin.
* BloodKnight: Lives for battle and laments about the lack of fighting in his time period. It was because of this that he is so eager to carry out an assassination mission for the Shogunate.
* BlowYouAway: When Mugen try to jump on him during the fight he simply turns around and a gale send Mugen and rubble flying.
* BornInTheWrongCentury: He's very sad about the lack of war in his time and tells this to Jin.
* CharlesAtlasSuperpower: His swordmanship makes him supernatural, even more than [[KiBlast Ukon]] and [[BlindWeaponMaster Sara]]. Mugen is severely outclassed in strength in speed making his self taught style worthless and while Jin's formal training fares better he can barely avoid Kariya's attack and only hit him once via [[spoiler: MutualKill]]. The only explanation given is his training that made him legend.
* CulturedBadass: When he's not fighting, he's tending a garden filled with flowers of all sorts.
* DishingOutDirt: When fighting on rocks he can make the ground collapse with what seems to be ki.
* DragonWithAnAgenda: Despite working for the Shogunate and loyally carrying out their will, he tells Jin that he's only interested in the chance to fight strong opponents that it brings him.
* EvilCounterpart: To Jin, reflecting that both of them are swordsman who hold values that are no longer relevant. But whereas Jin gradually becomes protective of those he cares about, Kariya seeks to manipulate others to get by.
* FinalBoss: He is Jin's final opponent, and is the deadliest swordsman he's faced.
* FlashStep: He moves so fast he can seemingly do this. Part of it is also misdirection of the enemy's senses.
* GlassCannon: He is by far the toughest, swiftest, and most skillful swordsman in the setting. [[spoiler: In the end, though, he ends up dying from a single stab to the gut.]]
* KiAttacks: It's highly implied he can use Ki in battle.
* MakingASplash: When he slashes at the water he creates a water wall in his wake. Just like Sara.
* ManipulativeBastard: He's actually manipulating the Bakufu itself in the shadow.
* ManBehindTheMan: [[spoiler:He's the one who ordered Mariya Enshirou to kill Jin.]]
* NonchalantDodge: Mugen and Jin can barely get close to him, let alone touch him.
* ObfuscatingStupidity: As shown in his introduction he looks like a meek, harmless middle-age samurai with a penchant for flowers. He's actually the greatest swordsman in the Shogunate, and has a personal agenda to boot.
* PowerOfTheGodHand: [[MasterSwordsman Kariya Kagetoki]] is known as the Hand of God due to his skills.
* RedBaron: The fabled "Hand of God". He surpasses his reputation. One can only wonder what he must have been like in his prime.
* WorldsBestWarrior: Considered the best swordsman in the series, though he notes there is a "paper-thin margin" between him and Jin. [[spoiler: Jin has to exploit a TakingYouWithMe to wound and kill him.]]

!!Isaac Kitching/Jouji
->'''Voiced by:''' Creator/HochuOtsuka (JP), Creator/PaulStPeter (EN)

A strange man who claims to be Japanese even though his accent, red hair and blue eyes suggest otherwise. After winning Mugen's and Jin's swords in an eating contest, he asks Mugen, Jin, and Fuu to give him a tour of Edo in exchange for the return of their swords, and tells them that his name is "Jouji".

His real name is Isaac and he represents the famous Dutch East India company, the Governor-General in charge of trade. Isaac was to meet with the shogun but wanted to see Edo instead, his subordinates had been delaying the meeting while looking for him. In an emotional scene, he reveals that he was persecuted in his homeland because of his homosexuality, and upon reading Ihara Saikaku's "Great Mirror of Male Love", hoped to find a more tolerant environment in Japan - only to find that here he's a distrusted foreigner. Fuu asks him if he's seen "The Samurai who smells of Sunflowers" and shows him her trinket. After examining it he warns Fuu to never show it to people and that it's dangerous to be showing it around at all in Japan.
* AsLongAsItSoundsForeign: No, that is not a Dutch name. Not that most Japanese (or Americans, for that matter) would realize it. (His surname really should be spelled Titsingh, after the real Dutch Governor-General to Edo at the time; either "Kitching" is just a guess/transcription from the Japanese pronunciation, or they didn't want to suggest that Titsingh had been gay.)
* BigEater: The only character in the series who can match Fuu's appetite.
* BiTheWay: Even though he is attracted by men, he first fell for the kabuki actor mistaking him for a women, so he is attracted to women, too (although that could've been in a non-sexual, aesthetic way).
* FunnyForeigner: Despite his claiming, as seen with his huge stature, his red hair and blue eyes.
* GentleGiant: This massive guy may be overenthusiastic and loud, but is a good soul at heart.
* GratuitousJapanese: He speaks a heavily-fractured Japanese, and struggles to supress his European mannerisms, such as making the sign of the cross when stating that he speaks the truth.
* {{Otaku}}: Given his extreme fascination with Japan and Japanese culture.
* SmallRoleBigImpact: Even though he appears in one episode, he causes significant developments in the story. What he tells Fuu not only provides a great deal of foreshadowing regarding later plotlines, but it also sets Fuu and her companions on the road to Nagasaki where they would eventually find "The Samurai who smells of Sunflowers."
* StraightGay: He went to Japan thinking that he would be accepted there, after reading a Japanese book about male homosexuality, and how unlike it Europe, it was not considered a sin, or a depraved lifestyle.

His next victim happens to be the head of a band of drug smugglers, yielding a packet of opium powder. He takes the drugs to Hikoichi for resale, but gets ratted out. Meanwhile, the doctor is telling him that it would take a hundred times his current funds to cure his mother's illness, and his mom is getting antsy because he won't tell her what he's up to. Fuu corners him at the same time the gang tracks him down, he takes her hostage and holes up in a warehouse.

* MilesGloriosus: Despite all his talking, this bufoon is not the great samurai he think he his.
* PluckyComicRelief: His overall role in the episode.
* RhymesOnADime: In the Italian sub, he speaks this way.
* SheathStrike: Parodied: when he starts fighting, he throws the sheath high in the sky, tries to block the incoming slash but gets disarmed. When he's about to give up, the sheath falls down on his opponent's head, knocking him out cold. He then claims it was his secret attack of the Flying Dragon.
* UglyGuyHotWife: Remember Osen from above? The busty, sexy, hard-drinking brunette? Well, she's his wife.

->'''Voiced by:''' Creator/ShowHayami (JP), Jeffrey Stackhouse (EN), José Luis Orozco (LA)

Born into the royal bloodline of the samurai, Ukon studied kenjutsu under the tutelage of Zuikou before he was sent on a voyage to the mainland. However, the journey was interrupted by violent seastorms and the boat he was traveling on was wrecked by the waves. Even so, Ukon survived the journey and he was found lying unconscious on the mainland by a group of shaolin monks, from whom he learnt of a mysterious fighting technique called [[DangerousForbiddenTechnique 'Hakkei']].
The tenth episode is a character study of this martial arts student-turned-renegade as he travels to challenge and defeat the fighters he encounters across the country in the hopes of achieving national recognition for what he deems to be superior fighting skills.
* APupilOfMineUntilHeTurnedToEvil: Is this in relation to his former teacher Zuikou.
* ArrogantKungFuGuy: Oh yes. It's also interesting to note that he takes pride in a martial artform that was taught to him by [[MartialPacifist shaolin monks]].
* BloodKnight: A very bloodthirsty one as well.
* DangerousForbiddenTechnique: The aforementioned Hakkei. He probably didn't know it was one of these.
* DudeWheresMyRespect: ...but only initially. By the time he gets to fight Mugen, he may or may not have confessed that he doesn't really care about this any longer.
* ItsAllAboutMe: This comes in spades.
* KiAttacks: Hakkei. It looks like a contact RazorWind that chops the insides of the victim.
* SerialKiller: 'He made the mountains his home, and he became a demon.'
* ThatManIsDead: He completes his transformation into 'Shoryuu' by announcing this trope in a private conversation he has with his former instructor.
* VillainousBreakdown: Aside from the motivation that gives him his reputation as ''tsugiri'', the reaction he has to Mugen duplicating his Ki blast with only a month of training (which betrays the possibility that it may have taken him much longer to practice with his own ki attacks) might be a flicker of this.
* WithGreatPowerComesGreatInsanity: It's loosely hinted that despite having trained rigorously at using Hakkei and knowing how to use it efficiently as a result, Ukon might not fully understand the power of his technique. When dojos kick him out because of his inability to understand or realise this fact, he became greatly insulted as he thought they simply did it to shun him. Although, in the conversation he holds with Mugen for the first time over the bridge, he shows that he appears to be aware of what he is turning into.

->'''Voiced by:''' Creator/ShozoIizuka (JP), Creator/BobPapenbrook (EN)

Formerly a martial arts teacher, with Ukon having been one of his most talented followers. Becomes a priest to compensate for being unable to stop his student from turning rogue. Offers Fuu and company food and shelter in return for help with maintaining the temple and other domestic chores. Appears to be a canny and an highly intuitive individual.
* TheAtoner: His failure to save his student prompted him to become a monk and devote his life to charity.
* BaldOfAwesome: It's big and shiny. Mugen compliments him greatly for it and gets rewarded accordingly.
* CharlesAtlasSuperpower: With subtle implications, and the justifications thereof.
* CoconutSuperpowers: He is highly intuitive, and has great reflexes. He may also have done some research into the art of Hakkei, and the explanation he gives to Mugen of the ''offensive'' uses of this technique gives fruition to that possibility.
* MisterExposition: The source of Ukon's backstory.

!!Momoi Seishirou
->'''Voiced by:''' Tomohisa Asou (JP)

Nicknamed 'the lightning dynamo', Momoi is a poser who lives by a false reputation as an accomplished dojo instructor and surrounds himself with a group of flunkies. Mugen goes after him in order to ask about the tsugiri, but is mistaken for the tsugiri himself. In the ensuing scuffle, the flunkies are quickly disposed of and in as much time, dynamo exposes himself for the coward that he is.
%%* DirtyCoward
* MilesGloriosus: His boasts and stories of his exploits are disproportionate to his actual claim to fame... which is nothing.

->'''Voiced by:''' Creator/KenNarita (JP), Erik Davies (EN)

A Shogunate official, infatuated with Kohza. He becomes Mukuro's collaborator in his plan to steal gold from a ship.
%%* TheMole

!!Otawa Hankichi
->'''Voiced by:''' Creator/ShowtaroMorikubo (JP)

A young shogunate ninja with a highly distracting facial mole and Yatsuha's underground counterpart. Before the story begins he apparently steals some of the forged koban to present as evidence. He ditches the gold in the river (where it is later found by Jin) but gets caught and withstands torture to protect Yatsuha's cover. Rescued (inadvertantly) by Mugen in a very painful state. Appears again at the end of the episode, leaning the unconcious Mugen against a tree outside of town, and expresses disbelief at Yatsuha's taste in men.

%%* DiabolicalMastermind

->'''Voiced by:''' Creator/AkioOhtsuka (JP), Creator/RichardEpcar (EN)

An Ainu warrior whose village was struck by an epidemic while he was away and torched by the Matsumae clan Han. Overcome with rage, he killed the official who authorized the burning. He was arrested and incarcerated, but escaped before he could be executed. His weapon is unique, a modified crossbow, called a Chu-Ko-Nu, that can repeatedly fire bolts.
%%* AntiVillain
* AutomaticCrossbows: Wields a chinese ''zhu ko nu''. Makes little sense, since he's an Ainu-
%%* CharlesAtlasSuperpower
* {{Determinator}} [[spoiler:Allows himself to be shot with burning arrows in order to get close to the leader of the Matsumae samurai hunting party and set him on fire.]]
* DullEyesOfUnhappiness[=/=]ThousandYardStare: In his flashback we see his eyes change from normal to this. Mugen compares them to the eyes of someone who has just died.
%%* InASingleBound
* FallGuy: For the death of his clan.
%%* FriendToAllLivingThings
* GenocideFromTheInside: The samurai hunting him believe he did this before attacking other samurai from their clan. [[spoiler:He didn't]].
%%* HeartbrokenBadass
* HeroicBSOD: When his wife died.
%%* LastOfHisKind
* NoOneCouldSurviveThat: But Mugen thinks that he does anyway.
* RoaringRampageOfRevenge: Against the Matsumae clan, who torched his village. Mugen's desire to duel him is merely a thorn in his side.
* WorthyOpponent: To Mugen, who becomes obsessed with killing him after their duel is interrupted.

!!Francisco Xavier III
->'''Voiced by:''' Creator/JurotaKosugi (JP), Creator/LexLang (EN), César Soto (LA)

A man who claims to be the grandson of the first Francisco de Xavier, an evangelist who introduced Jesus to Japan. He deceives an underground Christian village into producing firearms for him to make money. His crown is shaved in the fashion of a Western monk, and he is highly amblyopic.
%%* BadHabits
* CollectorOfTheStrange: Has a collection of pictures (some of which should be elsewhere) and items belonging to famous warlords from the past.
* EvilColonialist: [[spoiler:Subverted, as he's actually Japanese]].
* GratuitousSpanish: In the Italian dub he speaks with a Spanish accent and uses Spanish words when speaking. Makes sense, since Xavier was of Spanish origins.
* TooDumbToLive: [[spoiler: He gets spared ''twice'' in the final confrontation with him. First by the girl he abused, then by avoiding a giant cross dropped on him. You think he would take a hint that the "fate" he's representing is trying to tell him something and he should quit while he's ahead. Instead, he he still tries to kill the heroes with his rocket launcher. By this point, his luck runs out when his gun backfires on him and kills him where he stands.]]

->'''Voiced by:''' Bon Ishihara (JP), Ismael Castro (LA)

An eccentric old hermit who fishes Jin out of the river after his fight with Sara. When Jin comes to, Johnny teaches him how to fish, and it is awesome.
* {{Cloudcuckoolander}}: ''He calls himself Johnny.''
* CrouchingMoronHiddenBadass: Despite the above trope, the first time Jin asks his name he replies "[[spoiler: Miyamoto Musashi]]." Whether he's serious or not is up for debate given the show's screwy timeline.
* EccentricMentor: Shows traits of this.
* ChekhovsSkill: The fishing lesson.

->'''Voiced by:''' Creator/KojiTotani (JP), Creator/TonyOliver (EN)

A mysterious man who claims to be a descendant of the Heike clan, searching where the clan's lost gold was buried. He convinces Mugen, Jin, and Fuu to aid him and his workers in digging for the gold, but Fuu discovers there's more to him than meets the eye...
* EmptyEyes: His eyes always have a lifeless, blank look in them, which is one of the first indicators that there's something not quite right about him.
* OurZombiesAreDifferent: [[spoiler:Despite his body apparently having been dead for some time, him consuming large amounts of wasabi has allowed it to keep from decomposing.]]

->'''Voiced by:''' Creator/ToshioFurukawa (JP), Creator/DaveWittenberg (EN)

A former ninja, a member of a hereditary elite guard that got shut down when the isolation order went into effect (that's how he's had enough contact with foreigners to know how to play baseball). He wears distinctive snazzy sunglasses. He is first seen sitting in a tree, balancing a baseball on his head. When Mugen runs past, fleeing from the restaurant staff, he jumps down and slugs him with the baseball. Mugen's return pitch is forceful enough to knock over a pagoda, and earn the trio a chance to get out of trouble by playing on Kagemaru’s baseball team.
* GratuitousNinja: A Ninja baseball player to boot.
%%* SacrificialLion
* SanitySlippage: Doubled with some {{Angrish}}. In sign language.
