[[folder:Yukishiro Enishi]]
->Voiced by: Creator/NozomuSasaki (JP), Bill Wise (EN)

The younger brother of Yukishiro Tomoe and the primary antagonist of the Jinchuu arc, the last major story arc of the manga. Enishi wants revenge against Kenshin since he killed Tomoe.
* AdaptationalHeroism: In the second OVA ''Reflections'', his [[ArmsDealer dark]] and [[SelfMadeOrphan bloody]] past is never mentioned and his plan is reduced to a kidnapping. His role is also greatly diminished, going from TheBigBad to a supporting antagonist.
* AlwaysWithYou: [[spoiler: At the end, Kenshin reminds us that the real Tomoe is kinder than anyone or anything and that she will watch over Enishi forever.]]
* AndYourLittleDogToo: He and his allies attack Kenshin's acquaintances, friends and loved ones to make him suffer.
* AnimalMotifs: The White Tiger.
* ArchEnemy: To Kenshin, shown in their [[TigerVersusDragon animal motifs]].
* ArcVillain: The last one of the series.
* ArmsDealer: How he sustained himself prior to his appearance in the manga. Also see {{Fiction 500}} below.
* TheAtoner: [[spoiler: Heavily implied to be Enishi's fate. Kenshin declares that because time "has begun moving for him again", [[HeelRealization only now has Enishi started to realize the weight of all that he has done]]. He says that Enishi will atone with his life and that if the Tomoe in his heart were to ever smile again, he must first atone for his sins and smile himself.]]
* AxCrazy: He is ''very'' prone to violent fits of rage.
* BadBoss: [[spoiler: He tries to have [[TheDragon Gein]] killed once he's served his purpose and so he doesn't compromise his plans in any way. He deserves it, but still...]]
* BerserkButton: Kenshin is this for him at times.
* TheBigBad: Of the final arc of the series.
* BloodbathVillainOrigin: Scores a lotta bonus points too, as horrifying as it is.
* CoolSword: His Wato is a fusion between the Tachi (the longer, curvier ancestor of the Katana) and a Jian (Chinese longsword). It has the reach and cutting power of a Tachi plus the flexibility and speed of a Jian.
* CulturedBadass: As to be expected from a mob boss. Though shallow, since on the inside, he's a hot mess.
* {{Determinator}}: He will stop at ''nothing'' to send Kenshin to a living hell of his own design. Case in point; he takes a heavy beating from Kenshin, but continues to fight like nothing happened. Why? The pain became ''unimportant to his brain''.
** As a child, he ate corpses and drank from mud puddles in Shanghai just so he could survive. The thing that stopped him from just dying on the streets? ''The desire to make Kenshin pay''.
* DisproportionateRetribution: The methods he and his "comrades" resort to ([[spoiler: blowing up property, injuring people, kidnapping Kaoru and faking her death etc.]]) are rather...''extreme''.
* EvenEvilHasLovedOnes: Enishi loves [[PromotionToParent Tomoe]] and is seen lamenting her death and his inability to protect her, as well as wondering why she had to die out loud. He also thinks she wants revenge as much as he does.
* EvilAlbino: He's not naturally an albino, but otherwise fits.
* EvilCounterpart: To Kenshin. For one thing, there's the TigerVersusDragon motif between them (Enishi as the tiger, Kenshin as the dragon), and also the fact that Enishi's Watojutsu just so happens to counter the Hiten Mitsurugi style. They both bear marks from Tomoe's death--Kenshin got the second part of his cross-scar and Enishi's hair turned white from shock--but whereas Kenshin became TheAtoner, Enishi went AxCrazy and obsessed with revenge.
* EvilOrphan: [[WhiteHairBlackHeart Well, what were they expecting?]]
* FateWorseThanDeath: At first, he wants to put Kenshin through a living hell. [[spoiler: After Kenshin snaps out of it, he thinks that Tomoe wants him to send Kenshin to the ''real'' hell.]]
* {{Fiction 500}}: Remember Shishio Makoto's battleship ''The Rengoku''? Yes, the one that's said to be able to blow Meiji Era Tokyo to ruins by itself? Enishi not only ''sold'' the evil warrior this ship, but claims to own an entire ''fleet'' of them.
* FreudianExcuse: He witnessed the death of his sister Tomoe and was thrust into a "living hell".
** The Excuse even influences his fighting style - he claims to have no use for defense, since Kenshin robbed him of the only person he ever cared about defending.
* FromNobodyToNightmare: He was once a relatively normal kid...now he's a dangerous criminal hell-bent on vengeance.
* GlassCannon: When activating the "Nerves of Insanity", Enishi has all his senses buffed to ridiculous degrees; becoming much faster, and nigh-impossible to hit. Any hit that does connect will hurt like hell, [[SensoryOverload since all his senses were amplified... including his sense of pain]].
* HairTriggerTemper: He throws his pistol at Kenshin's face the ''moment'' Tomoe's name escapes his lips.
* {{Hypocrite}}: He calls out Kenshin on the lives he took as Battousai, when he himself has taken lives in cold blood.
* ItsAllAboutMe: Everything he does somehow connect back to his desire to bring revenge upon Kenshin.
* {{Jerkass}}: He shows no concern or consideration for any of his comrades, treats his second-in-command like dirt and only cares about avenging his sister.
* KatanasAreJustBetter: The origin of his [[CoolSword Wato]]: the Chinese were so impressed by the swords used by the Wako (Japanese pirates) that they decided to adopt them for their own armies and modified it into the Wato.
* KnightTemplarBigBrother: {{Inverted}}. He's a Knight Templar ''Little'' Brother. He left Edo when he was only eight/nine ''just'' so he could help his sister with revenge.
* LackOfEmpathy: He wants revenge on Kenshin for his AccidentalMurder of Tomoe, but he only allies with his comrades because he sees them as useful in revenge.
* LennonSpecs: Sporting a pair of [[Music/TheBeatles John Lennon]] shades in the Meiji era is cool! [[spoiler: Shame they get broken at the end.]]
* LovingAShadow: He comes to see [[spoiler:Kaoru]] as a ReplacementGoldfish for Tomoe during his blurriest moments, to the point that [[spoiler: he hallucinates that she ''is'' Tomoe during his final fight with Kenshin.]]
* TheManBehindTheMan: [[spoiler: Enishi's actually the one from who Shishio bought the ''Rengoku'', though he was worried when he heard that Shishio and Kenshin clashed. The ''To Rule Flame'' side-chapter established that Enishi intended to sell it to another ambitious Japanese officer, but Shishio killed that man and then took the initiative to take up Enishi's business deal. Shishio threatened to kill Enishi and steal the ship if he didn't comply.]]
* ManipulativeBastard: He recruits warriors (some of whom also have grudges against Kenshin) so they can aid him in his revenge. However, Enishi never intended to let any of his comrades rob him of his Jinchuu and actually ''expected'' them to be defeated.
* MasterSwordsman: He taught himself Watojutsu and became skilled enough to fight Kenshin on equal ground, to the point where he can defeat most of the attacks in Kenshin's arsenal.
* TheMentallyDisturbed: He is ''severely'' disturbed because he witnessed the death of his sister and the trauma is very apparent. His hair went white soon after, he hallucinates seeing Tomoe and if he tries to harm young women he becomes physically ill. [[AxCrazy To say nothing of his violent behavior.]] The man is clearly not well.
* MindRape: Unleashes a non-supernatural one on Kenshin as part of his plan, by [[spoiler: kidnapping Kaoru and leaving a puppet impaled by his sword in her place, which sends Kenshin ''dangerously'' close to the DespairEventHorizon.]]
* NoSympathyForGrudgeholders: Even though Kenshin believes that his grudge is perfectly understandable, the methods he and his comrades resort to are rather extreme. Kenshin calls him out on these unjustified acts of violence that have resulted in people being injured and nearly losing their lives as Enishi didn't focus on him specifically. At the end though, the two resolve their conflict with a fair duel, which Kenshin is happy to accept.
* ThePowerOfHate: Explains why he's so powerful even before increasing his nerves. According to him, he has hated Kenshin ''so much'' since he killed Tomoe that his brain maintained a constantly active state, even during sleep. He seems to solely ''function'' on that hatred alone.
* PrematurelyGreyHaired: Enishi's hair went white after he witnessed Tomoe's untimely death. When Kenshin sees him for the first time after her death at the Battle of Toba-Fushimi, he has pure white hair and glares at his brother-in-law. It's clear at that point that the experience [[DrivenToMadness knocked several screws loose...]]
* PsychopathicManchild: Has shades of this. Despite how dangerous he is, the way Enishi communicates with his dead sister, his obsession with wanting her to smile (believing he can do anything if she does) and his extreme admiration for her can come off as very childlike.
* RedemptionEarnsLife: [[spoiler: He escapes from custody and disappears into the same town Kenshin was at during his HeroicBSOD and meets his father again, though they don't seem to completely recognize each other. He tells Enishi that he will someday leave that place and find new purpose in life.]]
* RevengeBeforeReason: He could've killed Kenshin multiple times, but felt that it was better to mentally torment him. [[spoiler: During their final battle, he refuses to kill Kenshin unless it's in a sword duel.]]
* RevengeMyopia: He wants revenge on Kenshin for killing Tomoe's fiancee and destroying her happiness, before killing ''her'' (though by accident) and taking away the only person Enishi loved. However, Tomoe never died hating Kenshin but instead tried to protect him. [[spoiler: He doesn't realize the truth until he is given her diary right at the end.]]
* ReverseGrip: Has this stance when he starts his ultimate attack.
* SelectiveSlaughter: Can't kill young women [[spoiler: because after what happened to Tomoe, he sees part of her in every young woman. It's what keeps Kaoru alive.]]
* SelfMadeOrphan: [[spoiler: When he was dying as a child in Shanghai, a wealthy Japanese family saved him from the brink of death and brought him back to health. According to him, he ''killed'' the family for their huge sum of money and simply because ''he couldn't bear seeing them happy...'']]
* SlasherSmile: Shows a ''really'' terrifying one when he's [[spoiler: about to kill Kaoru after defeating Kenshin.]]
* TheSyndicate: Was a major Shanghai-based weapons dealer for a time, but retired as he became such to fund Jinchuu. He has promised his organization to his second-in-command once that is accomplished.
* TalkingToTheDead: Throughout the arc, he is seen conversing with the apparition of Tomoe that lives in his heart. As long as she smiles, he can do anything.
* TigerVersusDragon: He is the tiger, Kenshin is the dragon.
* TheUnfettered: The only line he draws is killing young girls, which reminds him of Tomoe's untimely death.
* UngratefulBastard: Played for laughs; while [[spoiler: holding Kaoru hostage, Kaoru]] points out that he obviously hasn't been using the kitchen and makes him food for several days, stating that it "takes as much effort to make food for two as it does one". He finds her cooking ''disgusting'' and spares no time pointing this out (yet still eats it).
* VillainousBreakdown: [[spoiler: All it took to send him over the edge was realizing that the apparition of Tomoe in his mind wasn't smiling at him. When Kenshin asks [[ArmorPiercingQuestion if she's still smiling]], he ''completely'' flips out. It leads to his defeat as he lets go of his sword at a crucial moment in the battle when the image still refuses to smile for him.]]
* VillainousBSOD: [[spoiler: When Enishi ends up in the same village Kenshin went to when he fell into despair, he has the same broken look as Kenshin did. Saito even says he is incapable of hurting anyone in this state. He's a complete wreck.]]
* WhiteHairBlackHeart: Originally had dark hair, but it became white due to the shock and stress of seeing his sister die.
* YouKilledMyFather: The reason behind his intense hatred for Kenshin is him killing his sister (by accident).

The last remaining descendant of a small group of people who mastered the art of mechanics in the Middle Ages. He creates puppet like suits out of corpses, most notably the Iwanbou series. He is actually an old man yet he is very strong due to controlling his heavy puppets for so long. The diamond edged steel wires he uses (Zankosen) to control his puppets can also be used as a weapon as they are sharp enough to cut flesh and break bone. Gein just wants to test out his creations and needs to be around men of battle to do it since according to him, the forefront of technology is always in battle.
* AdaptationalAttractiveness: From an old man in the original manga to bishonen young guy in the Restoration manga. In the films, he has a disfiguring scar on the left half of his face but is still much younger and more fit than his manga incarnation.
* AdaptationalHeroism: In the film, he becomes a CompositeCharacter with Hannya, and as such has a few of the man's more noble traits. In addition, many of his own heinous actions are AdaptedOut on account of him having a different role in the film.
* BadassGrandpa: He's revealed to be quite old under his mask, and admits that he must be at least twice Kenshin's age.
* BloodKnight: The plotting type, and one that proves how scary it can be when {{Blood Knight}} and {{Evil Genius}} get together. He doesn't like war for its own sake but does see it as an opportunity to test his creations against appropriately strong opponents. And if he can make a buck doing it...
* BunnyEarsLawyer: Has shades of this, for example when he asks if the "Six Comrades" can be renamed "Gein and his Merry Men" instead.
* CompositeCharacter: In the films, he is a disfigured ninja like Hannya, and he is a ''kodachi''-wielding enforcer of Kanryu like Aoshi. His general appearance(lithe, muscular, light-haired) closely mimics Enishi's.
* CrazyPrepared: The various mechanisms he installs in Iwanbou 03, to prepare for fighting Kenshin.
* TheDragon: To Enishi. Unusual in that he's much, ''[[BadassGrandpa much]]'' [[OlderSidekick older]] than the {{Big Bad}}.
* EvilGenius: While he's not ''the'' {{Evil Genius}} in a {{Five Bad Band}} sense, functioning instead as Enishi's [[TheDragon Dragon]], he's for sure ''an'' {{Evil Genius}}, with shades of 19th Century {{Steampunk}} {{Mad Scientist}}.
* GiantRobot: Several of his puppets border on this.
* HoistByHisOwnPetard: [[spoiler:Killed in a trap he set for Aoshi. Good riddance.]]
* HypocriticalHumor: Played for laughs when he asks Mumyoi to show his face. This coming from a guy who's always masked.
* {{Irony}}: Lampshaded by Saitou: [[spoiler: He always masked himself with a skull. When Aoshi finished with him, his charred skull was the only thing left of him.]]
* KillItWithFire: [[spoiler: He's burnt to a crisp by Aoshi. With his own oil.]]
* MadArtist: Listen to one of his rants about the functional beauty of his puppets. He even refers to himself as a "Mechanical Artist", thus combining this trope with {{Mad Scientist}} for a truly screwed-up time. Heck, when [[spoiler: Aoshi kills him]] it's while he's trying to get back his [[spoiler: Kaoru]] doll, which he regards as his greatest masterpiece, one that can "rival the creations of god." [[AGodAmI Complex much?]] It's okay though, most people seem to see him as just some weirdo.
* MarionetteMaster: Uses his puppets as his main weapons, fighting from inside of them. Made even worse by the fact that they're built from corpses.
* MaskPower: Spends most of the series wearing a concealing facemask that hides both his identity and age.
* MeaningfulName: Watsuki derived his name from American serial killer Edward Gein, who actually ''flayed his victims' corpses'' and made ''upholstery'' from them.
* TheMole: Infiltrated [[spoiler: Shishio's group]] for Enishi [[ObfuscatingStupidity disguised in one of his puppets]] so that he could keep an eye on Kenshin.
* MusclesAreMeaningless: He's the smallest and shortest of the companions. And yet, has enough strength to use the Iwanbou puppet with ease.
* OlderSidekick: To Enishi.
* PsychoForHire: A more subtle example. He's not in it for the sadism (although still a factor). But he needs opportunities to test out [[spoiler: the Iwanbou series]] and working for whack-jobs like Enishi provide plenty of them. If a normal {{Psycho for Hire}} sees the job as a way to get off, Gein sees it as a chance for intellectual masturbation. In a way, it's kinda worse.
* RazorFloss: When outside of his puppets, he uses their wires as offensive weaponry. He's good enough to slaughter a boatload full of thugs and give Aoshi a run for his money.
* SparedByTheAdaptation: [[spoiler: He acts as one of Takeda's assassins in the ''Restoration'' manga and fights Saitō who, surprisingly enough, lets him live. The live-action film also ends with him crippled by Kenshin but not dead.]]
* VillainousBreakdown: He totally snaps [[spoiler: after Aoshi tells him that he burned Kaoru's puppet.]]
* YouCouldHaveUsedYourPowersForGood: Kenshin tells him this during their battle, to which he replies that [[ShutUpKirk technology always finds its greatest uses on the battlefield.]]

[[folder:Kujiranami Hyogo]]
A huge man with an odd mouth and only one arm, as he lost it to Kenshin during the Bakumatsu period. Looking for revenge, he sided with Enishi. He goes berserk at the mention of Kenshin and can put an Armstrong cannon on his arm stump to fight.
* AchillesHeel: Kenshin manages to knock him out by striking his armpit. Later Yahiko manages to hurt him by hitting the stump connecting his arm to the cannon.
* ArmCannon: Has an Armstrong cannon built into his missing arm. Later becomes a GrenadeLauncher, complete with rapid fire and BayonetYa.
* BerserkButton: Kenshin. Believe it or not, he has an even ''worse'' one; [[spoiler:refusing to kill him, when you defeat him.]]
* TheBerserker: Alternates between this and TheJuggernaut.
* BookEnds: On his first appearance, he thanks Tae for her kindness. [[spoiler: After his defeat he thanks Yahiko and Kenshin for their kindness.]]
* TheBrute: Shares the role with Banjin, though he's calmer and more level-headed outside of battle.
* {{Expy}}: Visually resembles [[ComicBook/XMen Apocalypse]]
* DisproportionateRetribution: He wants revenge because Kenshin severed his arm, leaving him incapable of continuing on as a samurai, but refused to kill him. Kujirinami considers himself shamed by this, and wants to take the price of his humiliation it out of Kenshin's hide. Notice though that from the point of view [[HonorBeforeReason of a samurai, being mutilated and spared like that would be a tremendous humiliation]].
* DontYouDarePityMe: Twice. [[spoiler: The second time though Yahiko talks him out of it.]]
* GagLips: See {{Expy}}.
* GetAHoldOfYourselfMan: How Kenshin manages to beat him--by cutting off the arm cannon. According to Aoshi, he remembered the shock of his first mutilation and, in doing so, ''restores his sanity''.
* {{Gonk}}: Being an expy of [[ComicBook/XMen Apocalypse]], he can certainly feel like this.
* TheJuggernaut: He's damn near unstoppable, and bigger than Anji.
* ManlyTears: [[spoiler: Cries out after accepting his defeat.]]
* MeaningfulName: Kujiranami means "Whale's Wave".
* NoNonsenseNemesis: Rather than wasting time or playing around, Kujiranami's main tactic is "drop down and shoot them all up". He's also very serious compared to his companions, being even sterner than Gein.
* OneHitKill: His [[{{BFG}} Cannon]], realistically, is treated as a huge menace because of its explosive hits. In the very first battle, the group's first priority is to stop him from shooting again.
* OnlySaneMan: Outside of battle among the other Six Comrades. In battle though he goes berserk.
* PetTheDog: When he's introduced for the first time, he goes into the Akebeko and asks for the cheapest dish. Tae decides to bring him a more expensive salmon and rice dish instead (at the cost of the cheapest dish), despite being warned that such a mercy may offend him. Kujiranami, however, after looking at her for a while, thanks Tae for her kindness. This is foreshadowing that he's not as bad as he looks.
* RedEyesTakeWarning: When he's on a rampage.
* SayMyName: "BATTOUSAI!!" Slips to MadnessMantra after his first defeat.
* SlasherSmile: He has only one in the whole manga, as he's about to nuke the Akebeko, but is pretty creepy.
* TalkingTheMonsterToDeath: It's ultimately Yahiko who gets him to give up his grudge by showing that even in the Meiji era, there's still some good he can do outside the battlefield.
* VillainousBreakdown: When Kenshin refuses to kill him after taking him down, he goes on a mindless rampage; being unable to say anything other than "Battosai". [[spoiler:Fittingly, it's Kenshin who snaps him out of it.]]

[[folder:Inui Banjin]]
Also known as "Iron Armored Banjin", is an hot blooded martial artist who holds a grudge against Kenshin for killing his master Tatsumi. Not very bright; he uses his whole body as a weapon and wields thick metal armor on his arms called "Tekko", which serves as a shield and Knuckleduster.
* AdaptationalComicRelief: Inverted. While he is somewhat comedic in the live-action film, the comedy isn't at his expense.
* AdaptationalHeroism: In the Live-Action film he's considerably less of a jerk and much more affable. His KickTheDog moments aren't quite as brutal, and when Sanosuke calls for a time-out in their brawl, Banjin obliges and happily accepts some wine from him.
* AxCrazy: Seen during his assault on the Maekawa dojo. The guy actually enjoys maiming and pummeling his opponents.
* AnimeHair: Dreadlocks in Meiji-era Japan?
* ArrogantKungFuGuy: His style is even named the Invincible Jusshiki Style.
* AvengingTheVillain: To Tatsumi, though it's actually an excuse. What he really wants is to test his own skills against Kenshin.
* BareFistedMonk: He's a brawler through and through but this is played up much more in the live action films. He fights exclusively with his fists and is a Christian Priest.
* BloodKnight: He lives to fight, his true motivation for joining the Six Comrades is so he can prove himself against the Battousai.
* BoisterousBruiser: The most action-prone of the group.
* TheBrute: More bloodthirsty and simple-minded than Kujiranami.
* DumbMuscle: Makes Sano look like a genius by comparison. At one point he unleashes a flashy attack that demolishes the gate of the Kamiya Kasshin Ryuu dojo without any actual reason, which is lampshaded by both Kaoru and Megumi.
* {{Expy}}: Of Kazuki Kazama from ''VideoGame/SamuraiShodown''.
* EvilCounterpart: With his odd dress, desire for fighting, and lack of intelligence, he's a clear mirror to Sano.
* GlassCannon: He's strong enough to deal a great deal of damage to Sano, but his gauntlets mask the fact that he can't take a hit.
* HighPressureBlood: Makes the mistake of trying to attack Sanosuke once more after receiving his Futae no Kiwami that shattered his new gauntlets. He ends up with blood squirting out of his arms' veins and arteries for his trouble.
* TheIdiotFromOsaka: Not as obvious as Cho, since his dialect is weaker. He does use some Osaka-ben terms (''bochi-bochi'', for instance), and is specifically stated to be from the region in character information from the most recent video games. The fact that he's an idiot is...kind of obvious, really.
* UsefulNotes/JapaneseChristian: His live-action counterpart explicitly crosses himself when he expresses sadness for a dead chicken and Sannosuke later refers to him as such. His black robes make him look like a priest and even the Funamation sponsored clips identify him as one.
* KickTheDog: Incapacitates a lot of dojo students and policemen for fun and even stomps on the unconscious Maekawa (the same guy who was defeated by Raijuta).
* MeaningfulName: His master Tatsumi's name literally means "Dragon Snake", referring to the fifth and sixth zodiacal signs. Inui means "Dog Boar", referencing to the eleventh and last zodiacal signs.
* PowerFist[=/=]LuckilyMyShieldWillProtectMe: Wears some really thick armlets called "Tekko". He can use them to punch people really hard, or (mostly) to parry blows and bullets. [[spoiler: Is eventually shattered by Sano's super attack.]]
* SlasherSmile: Sports one many times, ''especially' when he's fighting.
* SmallNameBigEgo: As Sanosuke pointed out, he's rarely fought strong people.
* TooDumbToLive: In the ''Restoration'' manga, he once again fights and loses to Sanosuke after his liquid armor fails against the latter's punches. So he covers ''himself'' in the liquid...only to realize he can't move. Way to go, idiot.

[[folder:Otowa Hyoko]]
The "Master of Hidden Weapons", is an effeminate assassin who just loves to kill people with his hidden lethal weapons. Wants to avenge his friend Nakajo, who was killed by Kenshin.

* AvengingTheVillain: Nakajo. However, this is just an excuse.
* CoolSword: The Bishamonken, a sword which [[spoiler: takes advantage of magnetic energy and iron sand dust to hit enemies even if the user is not skilled at sword fighting.]]
* DirtyCoward: [[spoiler: Which leads to his fall, as he's so scared of Kenshin that he doesn't pay enough attention to Yahiko and ends up on the wrong end of his Hawatari.]]
* {{Expy}}: Partly based on [[VideoGame/SamuraiShodown Sogetsu Kazama]], while his mantle-like thing is borrowed by Sinister.
* ForTheEvulz: He likes killing for the fun of it, his friend's death is merely an excuse to satiate his bloodlust.
* FragileSpeedster: Fast or not, he doesn't have much stamina as even Yahiko is able to hurt him.
* GoodSmokingEvilSmoking: Seen smoking from a narghilé-like thing while resting at Enishi's place.
* {{Guyliner}}: Wears lipstick.
* HollywoodAcid: He mentions acid amongst his hidden weapons, but he never uses it.
* InformedAbility: We're told that he has [[ThirteenIsUnlucky 13 hidden weapons]] with him. We only see five in action: Kaiga Chuzen (a tiny hidden dart launcher), Kasui Busuen (cubes that release a toxic cloud when thrown in water), the Bishamonpun (a special iron sand dust), the Bishamonken (a sword with magnetic powers used along with said dust) and [[spoiler: Riku Doko (the six ornaments of his collars used as sharp tentacles)]]. We also see (though not in action) some darts, a tube-like weapon, a dagger resembling a winding key and a knucklerduster/axe hybrid.
* MasterPoisoner: Kasui Busuen are simply poison cubes that creates a cloud when wet.
* SissyVillain: Unlike Kamatari, he looks more like a DragQueen, though isn't explicitly stated to be gay.
* SpiderLimbs: [[spoiler:His odd mantle can actually function as a bladed weapon, which he uses to impale Yahiko.]]
* VillainousBreakdown: Post-Knock Out. [[spoiler: The others notice he went down with a smile on his face. Unable to believe someone not even in his age range was able to beat him.]]
* TheWorfEffect: He's defeated by [[spoiler: Yahiko, though to be honest it was pointed out that Otowa was too distracted by Kenshin's aura to fully concentrate on Yahiko.]]

[[folder:Yatsume Mumyoi]]

A grotesque-looking ninja with overly long arms. Was defeated by Kenshin long ago and now wants revenge.
* AnimalMotif: The Spider. He's often compared to one, has long skinny limbs, can move underground and is usually hidden.
* BerserkButton: Don't you even ''dare'' call him a freak, monster or just insult his clan. The fact that Saito trolled him on this lead to his VillainousBreakdown.
* CreepilyLongArms: He comes from a clan of gold diggers, where children's arms and legs are slowly stretched as they grow up by putting a set of iron rings on their limbs, just like the long-necked women in Africa.
* {{Determinator}}: His arm gets impaled with a katana. His reaction? ''Twist it'' so that it'll serve as a crutch to hold his arm.
* DishingOutDirt: Dosha no Bokei (Dirt Rampart), which takes advantage of dust and dirt to shield his attacks. It managed to nullify Saito's Gatotsu. Done properly, it is similar in function to Kenshin's own ''Do Ryu Sen'' (granted, that's one of Kenshin's standard, weaker attacks).
* TheDarkChick: The weirdest of the gang, for both the Six Comrades and the Yaminobu. And that's saying something, considering the Six Comrades has an ComicBook/{{Apocalypse}} expy and a BadassGrandpa who doubles as a MadArtist
* FangsAreEvil: Thanks to sharpening his teeth and treating them with bone dust to make them stronger.
* TheGrotesque: And is very sensitive about this.
* {{Expy}}: Of ComicBook/{{Venom}}. His claws and some of his moves are also similar to those of [[VideoGame/SamuraiShodown Gen'an Shiranui]].
* MundaneUtility: His long arms and digging talents were originally intended for gold mining. When the gold dried up, he decided to use them to make money as a hired killer.
* {{Ninja}}: He doesn't even show himself often because of his appearance.
* OverlyLongTongue: According to him, he had it since he was born and was the only thing that wasn't purposely altered, prompting Saito to call him a monster once more.
* TrainingFromHell: The iron rings that stretched his arms were really painful. After his first humiliating defeat at Kenshin's hands, he underwent it ''again'', which is even more painful for an adult.
* VillainousBreakdown: Flies into a murderous rage when Saito insults him, then that rage turns into desperation when Saito stabs his arm. Finally, he simply crumbles in a fetal position and cries as Kenshin spares him.
* VillainousValor: Became a ninja in order to help his starving clan so that they can have a decent life. After his defeat Kenshin suggests that he should give up his life as a shinobi and help them instead.
* WolverineClaws: Wears some on his longest arm.
* TheWorfEffect: Or the Saito Effect, as you wish. Either way, it gets messy.

[[folder:Wu Heishin]]

A Chinese crime lord and Enishi's number two in the organization. However, he's not interested in his revenge, he only wants to control the organization.
* BigBadWannabe: He believes he deserves to be the number one villain. Both the Kenshin-gumi and Enishi prove that he's just a fly in the grand scheme of things.
* {{Expy}}: A SmugSnake who hides behind stronger men and gets his jaw crushed in the end. Essentially a Chinese Takeda Kanryu who deals with weapons instead of opium.
* NonActionGuy: He can't fight. He has his bodyguards for it.
* OhCrap: When his bodyguards go down like paper. Gets an even bigger one when he runs into Enishi, who made it very clear that Heishin was to never show his face in front of him again.
* SmugSnake: He likes to talk big about his authority over Enishi's organization, but hides behind his bodyguards and will immediately bolt if things get bad.
* VillainousBreakdown: When his henchmen are defeated. [[spoiler: He even tries to murder Kaoru for real, but is knocked down by Enishi.]]

[[folder:The Sushin]]
Identical quadruplets serving as Heishin's bodyguards. They're named after the four gods of Si Ling, and each of them has a special weapon and ability: Seiryuu is the best at reading techniques, Suzaku is the most skilled at copying them, Byakko has the strongest attack while Genbu is the most careful.
* BladeOnAStick: Seiryu's giant halberd.
* BloodKnight: All of them like to kill people a bit too much.
* CallingYourAttacks: Byakko does this to a ludicrous extent: each of his attacks has a different position for the fingers and a different, odd-sounding name.
* CoDragons: To Heishin.
* CurbStompBattle: They last roughly one chapter each.
* DidntSeeThatComing: Suzaku manages to block and imitate every single one of Aoshi's Kodachi Nitoryuu techniques, even his Kaiten Kenbu Rokuren, but is suddenly taken by surprise and defeated when Aoshi decides to kick his fat ass with Kenpo instead.
* DualWielding: Suzaku's twin swords.
* GettingCrapPastTheRadar: One of Byakko's many combinations (whose name sounds like "repelling the invader") has him hitting while giving the middle finger at the same time.
* MirrorMatch: Pretty much how their battles turn out. Invoked as they specifically look for the opponent who's better suited for them.
* NoSell: Seiryuu manages to see through Saitou's Gatotsu and counter it a couple of times, wounding him in the process. However, as Kenshin pointed out, Saitou can't be defeated by simply defeating his technique. Suzaku does the same to Aoshi's Kodachi Nitoryuu's attacks, rending them useless. On the other end of the scale, Byakko gets frustrated that none of his strikes even faze Sanosuke.
* PowerFist: Byakko can turn his spiked armlets into knuckledusters.
* PsychoForHire: Literal bodyguards for hire and they seem to have a mean streak too...
* SimpleStaff: Genbu wields a six-sectioned staff. [[spoiler: However because of the sections, it's more fragile than normal staves.]]
* SlasherSmile: Going hand-in-hand with being [[BloodKnight Blood Knights]], they love to flash these whenever they enter battle, especially when they feel it will end in their favor. Seiryu differs slightly in that he tries to cover his smile in order to give the impression of a serious and disciplined fighter.
* SmallNameBigEgo: They claim to be really powerful. They're wrong. ''So so wrong...''
* TattooedCrook: The only way to tell them apart are the tattoos on the sides of their heads. Seiryuu has scales, Suzaku has a feather, Byakko has stripes and Genbu has a hexagonal turtle shell. They also have the kanji for their names on their foreheads.
* VillainousBreakdown: Genbu, the staff user Yahiko fights. He figures since he's JustAKid he can take him easily. Not only is he proven wrong but Yahiko shows to be much more of an expert about his weapon than he is and forces him into a position that he'll lose either way (He tries to step back from Yahiko, he's wide open to an attack. He doesn't, he loses his weapon). The only thing he can think of while trying to figure a way out of it is to continue thinking that Yahiko's just a kid to the point of being a MadnessMantra.
* TheWorfEffect: Even the author admitted that he made them as tailored, anticlimactic bosses so that Kenshin's companions would have something to do in the final battle.
** Enishi even makes it clear that the four of them wouldn't be able to defeat him if they tried taking him on.
