->Voiced by: Creator/NozomuSasaki (JP), Bill Wise (EN)

The 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 [[spoiler:Kenshin killed Tomoe]].
-----
* AnimalBattleAura
* AnimalMotifs: The 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.
* AxCrazy
* BadBoss: He shows no empathy whatsoever for his subordinates, and even [[spoiler: trying to have his [[TheDragon Dragon]] killed once he's served his purpose. He deserves it, but still]].
* BerserkButton: Kenshin is this for him at times.
* BloodbathVillainOrigin: Fits all of the classic criteria, horrifying as it is.
* CoolShades: Sporting a pair of [[Music/TheBeatles John Lennon]] shades in the Meiji era is cool!
* CoolSword: His Wato is the fusion between the Japanese 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.
* CreepyChild: The first time Kenshin sees him after Tomoe's death has him see that his hair has gone pure white and he's sporting a SlasherSmile. Things don't get much better the next time they meet.
* CulturedBadass: though shallow, since inside, he's a mess inside.
* {{Determinator}}: He will stop at ''nothing'' to send Kenshin to a hell of his own design. Case in point; he takes a heavy beating from Kenshin, but continues to fight like nothing happened. Why? His body ''stopped registering pain.''
* DiseaseBleach: The shock of witnessing his sister's death bleached his hair.
* EvilAlbino: He's not naturally an albino, but otherwise fits.
* EvilCounterpart: To Kenshin. For one thing, there's the TigerVersusDragon motif between them in terms of their fighting styles (Enishi as the tiger, Kenshin as the dragon), and also the fact that Enishi's Watou-Jutsu just so happens to perfectly counter the Hiten Mitsurugi style. Also, they both bear trauma-marks from Tomoe's death--Kenshin got the second part of his cross-scar, while Enishi's hair turned white from the shock--but whereas Kenshin became TheAtoner, Enishi turned AxCrazy and hell-bent on revenge.
* EvilOrphan: Killed an entire family just because he hated seeing them happy.
* FateWorseThanDeath: What he wants put Kenshin through.
* {{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 is an arms dealer so ''ludicrously'' wealthy and powerful he not only ''sold'' the evil warrior this ship, but owns a ''fleet'' of them.
* FreudianExcuse: His beloved sister's death. And it doesn't even come close to justifying his lunacy.
* 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 however, will hurt like hell, [[SensoryOverload since ''all'' his senses were amplified]]; including his sense of pain.
* HairTriggerTemper
* {{Hypocrite}}: He calls out Kenshin on the lives he took as Battousai, when he himself has taken lives, in cold blood.
* ItsAllAboutMe: Even as a child, his main objection to Tomoe going away was that she wouldn't be there to care for him.
* [[KnightTemplarBigBrother Knight Templar Little Brother]]
* LackOfEmpathy
* LimaSyndrome: He maybe becomes fond of [[spoiler:Kaoru]] or could just mentally be unable to kill her.
* LovingAShadow: He comes to see [[spoiler:Kaoru]] as a ReplacementGoldfish for Tomoe during his most blurry moments, to the point that [[spoiler:he hallucinates that she ''is'' Tomoe during his final fight with Kenshin]].
* TheManBehindTheMan: The man behind Shishio.
* ManipulativeBastard
* {{Master Swordsman}}
* TheMentallyDisturbed: Has hallucinations of his dead sister, whom he has had a StalkerWithoutACrush relationship with since childhood and has a sadistic HairTriggerTemper... yeah, he needs help.
* MindRape: Unleashes a non supernatural one on Kenshin as part of his plan, by [[spoiler: kidnapping Kaoru and leaving a mutilated puppet in her place, which sends Kenshin dangerously close to the DespairEventHorizon.]]
* [[spoiler: RedemptionEarnsLife: Sure, he was arrested, but he not only was given his sister's diary, but he escaped prison and disappeared into the exact same town Kenshin was at during his DespairEventHorizon.]]
* RevengeBeforeReason: 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
* ReverseGrip: Has this stance during his strongest attack.
* [[spoiler: SelfMadeOrphan: He killed his rich Chinese adoptive family for the money ''and'' because he couldn't stand seeing the family's happiness after his own happiness had been taken from him.]]
* SelfMadeOrphan: He murders his adoptive family in cold blood, because ''he couldn't bear seeing them happy.''
* SelectiveSlaughter: Can't kill young women [[spoiler:because of what happened to Tomoe]].
* TheSociopath: He has a lack of empathy for ''anyone'', including his own sister's feelings. [[spoiler: This trait carries over to adulthood to the point he can't see anyone else happy.]]
* TheSyndicate: Was a major Chinese-based crime lord for a time, but retired as he became such mainly to fund his elaborate revenge scheme against Kenshin. He has promised his criminal empire to his [[TheDragon second-in-command]] once that is accomplished.
* TigerVersusDragon: He is the tiger, Kenshin is the dragon.
* TheUnfettered: The only line he draws is killing young girls, that remind him of Tomoe.
* 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, on the other hand, finds her cooking disgusting and spares no time pointing this out (yet still eats it).
** Not played for laughs: [[spoiler: When he's taken in by a kind family in Shanghai, he kills them all and steals their fortune.]]
* UnintentionallyUnsympathetic: Perhaps should be named the TropeNamer.
* VillainousBreakdown: A very insane one. As the final battle between him and Kenshin wears on, he's dumbfounded that Kenshin is able to stick to his beliefs despite everything he's done to him. [[spoiler: All it took to send him over the edge was realizing that the apparition of Tomoe in his mind was no longer smiling at him. When Kenshin asks an ArmorPiercingQuestion if she she's still smiling, he completely flips out. It leads to his defeat as he loses the will to fight at a crucial moment in the battle when the image still refuses to smile for him.]]
* WhiteHairBlackHeart
* Yandere: Behavior-wise, yes. Unknown about romantic feelings towards Tomoe, though.
* [[YouKilledMyFather You Killed My Sister]]

!!'''Gein'''
http://static.tvtropes.org/pmwiki/pub/images/tumblr_m4iuodvwaf1r4fbq9_8532.jpg
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, [[spoiler: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.
-----
* BadassGrandpa: He's revealed to be quite old under his mask. If what he said to Kenshin is true, he's supposedly 56 years old.
* 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 it's 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.
* 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.
* [[spoiler:HoistByHisOwnPetard: 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.]]
* [[spoiler:KillItWithFire: 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]]?
* 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 almost 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's acts as one of Takeda's assassins in the ''Restoration'' manga and fights Saitō who, surprisingly enough, lets him live.]]
* VillainousBreakdown: He totally snaps [[spoiler: after Aoshi tells him that he burned Kaoru's puppet.]]

!!Kujiranami Hyogo
http://static.tvtropes.org/pmwiki/pub/images/kujiranami_1968.jpg
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.
----
* 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.
* TheBrute: Share the role with Banjin.
* {{Expy}}: Of [[ComicBook/{{X-Men}} 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.
* 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}}
* TheJuggernaut: He's damn near unstoppable, and bigger than Anji.
* 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 more stern 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.
* 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.
* SayMyName: "BATTOUSAI!!" Slips to MadnessMantra after his first defeat.
* TalkingTheMonsterToDeath: It's ultimately Yahiko who gets him to give up his grudge by showing that even in the Meji 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.]]

!!Inui Banjin
http://static.tvtropes.org/pmwiki/pub/images/250px-banjin_ken-706_2593.png
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.
----

* AxCrazy
* AnimeHair
* ArrogantKungFuGuy: His style in even named the Invincible Jusshiki Style.
* AvengingTheVillain: To Tatsumi, though it's actually an excuse. What he really want is to test his own skills against Kenshin.
* BloodKnight
* 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.
* {{Expy}}: Of Kazuki Kazama from ''SamuraiShodown''.
* EvilCounterpart: With his odd dress and desire for fighting, he's a clear mirror to Sano.
* GlassCannon: He's strong enough to deal a great deal of damage to Sano, but his tekkou mask the fact that he can't take a hit.
* KickTheDog: Slaughters a lot of policemen for fun.
* 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
* 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.

!!Otowa Hyoko
http://static.tvtropes.org/pmwiki/pub/images/250px-hyoko_ken-706_6875.png
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
* {{Expy}}: Partly based on [[SamuraiShodown Sogetsu Kazama]], while his mantle-like thing is borrowed by Sinister.
* ForTheEvulz
* {{Guyliner}}: Wears lipstick.
* 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.
* [[spoiler: SpiderLimbs: 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.]]

!!Yatsume Mumyoi
http://static.tvtropes.org/pmwiki/pub/images/968311-sa_large_5187.jpg
A grotesque-looking ninja with overly long arms. Was defeated by Kenshin long ago and now wants revenge.
----

* 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}}: Gets impaled in his arm 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.
* TheDarkChick: The weirdest of the gang.
* FangsAreEvil: Thanks to sharpening his teeth and treating them with bone dust to make them stronger.
* {{Expy}}: Of ComicBook/{{Venom}}. His claws and some of his moves are also similar to those of [[SamuraiShodown Gen'an Shiranui]].
* {{Ninja}}
* OverlyLongTongue
* WolverineClaws: Wears some on his longest arm.
* TheWorfEffect: Or the Saito Effect, as you wish.

!!Wu Heishin

A chinese crime lord, he's Enishi's number two in the organization. He's, however, not interested in his revenge, but he only wants to control the organization.

* BigBadWannabe
* NonActionGuy: He can't fight. He has his bodyguards for it.
* OhCrap: When his bodyguards go down like paper.
* SmugSnake
* VillainousBreakdown: When his henchmen are defeated. [[spoiler: He even tries to murder Kaoru for real, but is knocked down by Enishi.]]

!!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.
* 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 two chapters each.
* DualWielding: Suzaku's twin swords.
* GettingCrapPastTheRadar: One of Byakko's many combination (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.
* PowerFist: Byakko can turn his spiked armlets into knuckledusters.
* PsychoForHire
* SimpleStaff: Genbu wields a six-sectioned staff.
* SlasherSmile: When they fight.
* 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 feather, Byakko has stripes and Genbu has an 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 them 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, anticlimatic 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.
