A list of characters and character-related tropes from ''Manga/BusouRenkin!''

[[folder:Kazuki Muto]]
-->Voiced by: Creator/JunFukuyama (JP), Creator/SteveStaley (EN)

TheHero of the story, Kazuki is a very well-meaning guy that enjoys helping people. At the start of the story, he's caught in the crossfire between Tokiko and a Homunculous and killed, but Tokiko gives him a Kakugane as a means of resurrecting him. He uses it to create a Busou Renkin later on.
* AllLovingHero: He's nice to everybody, he tries to save everybody, and even helps people who were killing him not five minutes before, even people who were killing him five minutes previously, then stop, then betray the truce, he'll ''still help them''!
* AmazonChaser: He is attracted to Tokiko's fighting skill.
* AnimeHair: While not as bad as his [[Anime/YuGiOh namesake]] he's got some weird hair.
* BadassNormal: Before getting his powers, facing down a giant snake-like homunculus with nothing but a steel pipe! Guy's got some guts,[[spoiler: even though getting them ripped out of him doesn't do him any good, he still manages to cope with it.]]
* BattleCouple: With Tokiko.
* {{BFS}}: His Busou Renkin, Sunlight Heart.
* BigBrotherInstinct: You better don't mess with his sister [[TheDitz Mahiro]].
* {{Bishonen}}
* BoringInvincibleHero: Deconstructed with the FirstEpisodeResurrection and just avoided the DecoyProtagonist trope.
* CantStayNormal: Had the chance to go back to his regular life after [[spoiler: Tokiko resurrected him with the Kakugane.]] [[JumpedAtTheCall He didn't take the offer, apparently.]]
* ChronicHeroSyndrome: Ready to jump whenever he sees anyone in danger. It actually got him [[FirstEpisodeResurrection killed in the first episode]].
* ClingyMacguffin: Since he'll die without his Kakugane.
* CovertPervert: He's a really NiceGuy and doesn't think that dirty, but he does have a PornStash.
* DeliberateInjuryGambit: Because he doesn't have a heart, Kazuki will oftentimes take a normally lethal hit to the torso in order to deliver a blow of his own.
* {{Determinator}}: Justified because of his new heart but even then it also makes you wonder how much more he can take.
* TheDulcineaEffect: Got his foo' self killed trying to save a chick he didn't even know. The kicker is that Tokiko didn't even need to be saved, as she was baiting herself in order to draw out the Homunculus and Kazuki was merely in the way. But luckily for Kazuki, Tokiko had an extra kakugane on hand in order to give him a second chance at life.
* EvenTheGuysWantHim: Papillon certainly does.
* FirstEpisodeResurrection: And purely on Tokiko's whim.
* HadesShaded: [[spoiler:As Victor III.]]
* TheHero
* HeroicSuicide: [[spoiler:He decides he must kill himself before he becomes a full Victor-Type and tries to destroy the world, since one of his alternate options failed and it seems the other won't be ready in time. Thankfully he doesn't have to go through with it in the end.]]
* {{Hypocrite}}: Papillon called him this for wanting to continue fighting him despite having been killed, comparing it to how he was practically on his death bed because of his illness and wanting to fight to continue to live. It's when Kazuki fights Papillon and says that he should stop killing and accept his fate that he begins to call Kazuki this, when Kazuki got a second chance. Of course the entire thing falls flat because Kazuki doesn't have to kill people in order to survive. [[spoiler: That chances after the whole Victor thing, but once again falls flat because Kazuki fights to find an alternative that means not having to siphon life from people.]]
* IDidntMeanToTurnYouOn: Does this multiple times to Tokiko, one notable example was him hugging her protectively while giving his InTheNameOfTheMoon speech, and he was [[ShirtlessScene shirtless]]. Cue LuminescentBlush. [[spoiler: Also arguably when he touches her scar at the very end]].
* IdiotHero
* LightningBruiser: Especially his [[CallingYourAttacks BURST THROUGH! MY BUSOU RENKIN!]] attack, which involves shooting forward super fast and super hard.
* LikesOlderWomen: To Tokiko's amusement.
* OfficialCouple: With Tokiko.
* OrdinaryHighSchoolStudent: He was just a normal high school student until he got killed by a Homunculus and Tokiko brought him back to life by implanting a Kakugane into his chest as a replacement heart.
* PowerDyesYourHair: [[spoiler:When Kazuki's Black Kakugane III awoke it transformed him into a Victor, giving him glowing white hair (light green in the anime).]]
* PurpleEyes
* RedOniBlueOni: Red Oni to Tokiko's Blue Oni.
* SecondYearProtagonist: He's the main character of the series and a second year high school student.
* SenselessSacrifice: In the first episode, he dies trying to save Tokiko, but Tokiko wasn't actually in any danger and was just luring Homunculus Mita into a trap.
* ShirtlessScene: Gets a couple, but prominently when [[spoiler:he turned into a Victor]] which could count as FanDisservice.
* ShonenHair: He has the typical spiky hair of a StockShonenHero.
* StockShonenHero: He's an optimistic and reckless IdiotHero with spiky hair and a {{Determinator}} who he refuses to back down from any opponent no matter how strong they may be. This strong will is fueled even further when he is cheered on by others. He cares a lot for his companions and will do anything to protect them. He also will risk his life to save complete strangers.
* SwordBeam: Sunlight Heart doubles as a BoomStick.
* UnskilledButStrong: Sunlight Heart makes him a LightningBruiser [[spoiler:and his ability to become [[StoryBreakerPower Victor can be very broken]]]] however he is also the least trained member of Alchemist Warriors.
* WalkingWasteland: [[spoiler:His Kakugane is actually the third Black Kakugane, thus giving him the power to counter Victor, though almost at the cost of his life-drain aura becoming stronger and killing everybody else]].

[[folder:Tokiko Tsumura]]
-->Voiced by: Creator/RyokaYuzuki (JP), Creator/TaraPlatt (EN)

Kazuki's savior and [[TheLancer lancer]], Tokiko introduces him into the world of alchemy and saves his life by giving Kazuki a Kakugane. Total badass.
* ActionGirl
* ActionGirlfriend: The series starts out with Tokiko resurrecting Kazuki from the dead after he got killed on the spot by a Homunculous. She proceeds to introduce him into the world of alchemy and becomes Kazuki's mentor and love interest.
* AlliterativeName: '''T'''okiko '''T'''sumura
* AntiHero: She's willing to ShootTheDog.
* BadassAdorable: She ''DEFINITELY'' has her moments.
* BattleCouple: With Kazuki.
* BelatedBackstory: Her origin is not revealed in the manga until the final issue, where it's revealed [[spoiler: she's the only person in her school who survived a homunculus attack, and ended up killing the homunculus (who had posed as a fellow classmate) with the Valkyrie Skirt, using the Kakugane which was being used to heal her wounds. She gained both her scar and her hatred of homonuculi during the incident]].
* BoringButPractical: Other alchemists get flashy StockSuperpowers. Tokiko just gets a bunch of extra limbs ending in sharp objects. Fortunately, it turns out that having extra limbs ending in sharp objects is '''incredibly good for killing people'''.
* CatchPhrase: Often yells something about her opponents' guts, such as her intentions to rip them out, splatter them etc; also OnTheNextEpisodeOfCatchphrase
* CombatPragmatist: She doesn't really fight fair.
* DeadpanSnarker: Whenever she isn't fighting.
* DefrostingIceQueen: She started out as somewhat cold to Kazuki, but starts growing attached to him over time and finally falls in love with him.
* DeliberatelyDistressedDamsel: In the first episode, Tokiko leaves herself wide open, leading Kazuki to think she is just an InnocentBystander. Nope. She's an Alchemist Warrior, and she was leading the MonsterOfTheWeek into a trap. Kazuki just got in the way and got killed for nothing.
* DontFearTheReaper: Her Busou Renkin's sub-name is Death Scythe, she's pretty to boot.
* EvenTheGirlsWantHer: Well Mahiro does anyway.
* FantasticRacism: Really, really hates homunculi or anybody who would [[TheQuisling help them]].
* FourIsDeath: Her Busou Renkin, "Busou Renkin of the Death Scythe: Valkyrie Skirt," has four blades.
* GoingCommando: She doesn't wear a bra, not like she needs one, but was it necessary to show her undress?
* GoodScarsEvilScars: It's noticeable, representing her status as an AntiHero, but it's even, showing her inherently good nature.
* TheHunter: Was the SoleSurvivor of a homunculi massacre, which explains her ruthless attitude toward them.
* ImprobableWeaponUser: Even more then Kazuki, it's four scythes on the end of robot arms attached at her thighs.
* TheLancer
* MagicSkirt
* MsFanservice: Averted for the most part, though, due to Watsuki making deliberate decisions to avoid this. For example, her Valkyrie Skirt was going to be an ''actual'' skirt (as in, the blades come out from under her skirt,) until he realized that it would result in a lot of accidental {{Panty Shot}}s.
* NewTransferStudent: She officially enrolls in Kazuki's school as a transfer student.
* OfficialCouple: With Kazuki.
* PerpetualFrowner
* RedOniBlueOni: Blue Oni to Kazuki's Red Oni. Though she gets quite excited during battle.
* ReluctantFanserviceGirl: Her clothes are always [[ClothingDamage getting ripped up]] and she reluctantly wore a bikini in one episode.
* RescueIntroduction: Subverted. Kazuki thought she was in danger of being attacked by Homunculus Mita, but she actually was just luring it into a trap.
* ScarsAreForever: The scar across her nose that she got from a homunculus attack. Actually, it could have been healed, but she wanted to keep it.
* SciFiBobHaircut
* SexyMentor
* SingleWomanSeeksGoodMan: She falls in love with Kazuki for his optimism, virtue, strong will and determination to protect everyone.
* SoleSurvivor: Of a homunculus attack on her school. She was rescued by Captain Bravo.
* SpiderLimbs: Her Valkyrie Skirt.
* TransferStudentUniforms: Keeps the uniform she transfers in with, but for a justifiable reason, as the long skirt used by Kazuki's classmates would interfere with the Valkyrie Skirt.
* TraumaInducedAmnesia: Has blanked out all of her life before being found by the Alchemic Army.
* {{Tsundere}}: She becomes angry whenever Kazuki does something really stupid, but she truly comes to love him.
* WeakButSkilled: Compared to Kazuki, her Busou Renkin specializes in precise and swift movement, as opposed to giant energy blasts. As Kazuki himself notes, it's almost completely lacking in flashy special abilities like most of the others, but the device's range of motion and her perfect control of it is beyond anything modern science could reasonably create, and incredibly deadly in its own right.
* ZettaiRyouiki: Grade B-.

-->Voiced by: Creator/MitsuakiMadono (JP), Creator/SpikeSpencer (EN)

Once known as Koushaku Chouno, a sickly loner [[TheUnfavorite despised by his family]], he became a homunculus and a [[LargeHam massive ham]] as well.
* AgentPeacock
* AmbiguouslyGay: Beyond his manner of dress, his obsession with Kazuki is nuts
* AnimalMotifs: Butterflies.
* BadassBookworm
* BadassNormal: In the second episode, he is riding around totally calmly on Washio's back, even when Washio is attacking and defending - from a few hundred feet up in the air. Including perfectly holding his balance during dives and blurringly-fast maneuvers. Not bad for a guy with an IncurableCoughOfDeath.
* BarelyThereSwimwear
* CardCarryingVillain
* TheChessmaster
* CombatSadomasochist: One of the saner examples of this (and more of a masochist than sadist), but he has shown what seems like arousal in reaction to injury, and on the sadist front, look at his commentary after eating his family.
* DoNotCallMePaul: Ever since he became an homunculus, he no longer responds when called "Koushaku Chouno". He only makes an exception to his WorthyOpponent Kazuki though.
* EmpoweredBadassNormal: He becomes a homunculus and gains his Busou Renkin.
* EvilIsHammy: [[CatchPhrase PAPIIII...LLON!!!]]
* EvilTastesGood
* FacePalmOfDoom: Delivers one to his asshole brother, and keeps it rolling from there. He appears able to ''consume people'' through creepy orifices in his palms--he just sucks them right in, leaving behind nothing but their empty clothes.
* FashionVictimVillain: Invoked to the extreme when he becomes a homunculus and dons...''[[http://img1.ak.crunchyroll.com/i/spire3/02082008/e/b/c/6/ebc66bc0ab6810_full.jpg this]]''. Most characters are utterly weirded out by him and his bizarre fashion sense.
* FauxAffablyEvil
* FriendlyEnemies: Toward Kazuki, with a massive amount of FoeYay on his part
* GlassCannon: Can blow people to smithereens with his Busou Renkin, Near-death Happiness, but suffers from a severe lack in stamina due to his disease.
* GoodCostumeSwitch: His purple butterfly logo turned orange in the finale.
* HeelFaceTurn
* HiddenDepths: Who knew the sickly wallflower Chouno Koushaku would become the shameless, flamboyant Papillon?
* HumansAreTheRealMonsters: 'Cause of a [[FreudianExcuse shitty childhood]] this is his personal philosophy.
* ImmortalityImmorality: Homunculi have to eat people, [[spoiler: but he doesn't--it's the desire of the homunculi to become human that drives them to consume human flesh, and since he hated his human life, he doesn't have to eat them.]]
* IncurableCoughOfDeath: Both before and after his transformation.
* ItsAllAboutMe: Subverted; he actually does nice things since they benefit himself as well, like [[EnemyMine helping]] Kazuki since [[TheOnlyOneAllowedToDefeatYou only he can defeat him]], [[WildMassGuessing well]] that's his [[IWasJustPassingThrough excuse]].
* MadBomber: His Busou Renkin allows him to create and control gunpowder, and he's rather crazy.
* NobleDemon: He is ruthless in his quest to become a Homunculus, but this is just because he's sickly and dying, and wants immortality. Once he's become a homunculus, he's content to just observe, provide covert aid for the heroes, wear a disturbingly flamboyant costume, and, in the end, become an urban legend to schoolgirls. It helps that, due to his imperfect metamorphosis, he doesn't need to eat humans like other homunculi do.
* OffstageVillainy: Its indicated that in order to transform himself, people had to die, including children, although Chouno didn't kill them himself (his minions probably did), but after that, he doesn't really do anything evil (although he makes threats that sound like those of an OmnicidalManiac).
* TheOnlyOneAllowedToDefeatYou: Takes it to the point where he's effectively one of Kazuki's most valuable allies. [[ArchEnemy Not that either of them have actually noticed this little detail.]]
* RefugeInAudacity
* SelfMadeOrphan: He ate his father, brother, and family bodyguards- doesn't come off as that bad though, since all were assholes.
* SissyVillain: He dresses in a flamboyant outfit including Speedos and a distinctive butterfly mask, and he certainly has a lot of FoeYay with Kazuki.
* TheStarscream: Can't stand being second best.
* {{Stripperific}}: His costume is essentially just a jumpsuit and a mask.
* StuffBlowingUp: His Busou Renkin, Near Death Happiness, takes the form of a pair of giant butterfly wings made of gunpowder that he can control and blow up at will.
* TeenGenius
* ThisIsMyNameOnForeign: ''Chou'' means butterfly in Japanese (the full surname would translate to "butterfly field") and Papillon is the French word for butterfly.
* TrouserSpace: He likes hiding things in his crotch... a little too much. Not having any pockets doesn't help.

[[folder:Captain Bravo]]
-->Voiced by: Creator/MasashiEbara (JP), Creator/PatrickSeitz (EN)

A captain of the Alchemist Warriors that Kazuki and Tokiko work for, Captain Bravo gives them advice and help on many occasions.
* AntiVillain: [[spoiler: Post-FaceHeelTurn.]]
* BadassLongCoat: It's one of his special powers.
* CallingYourAttacks: BRAVO!!! ______!!!
* CatchPhrase: It's all in his name.
* CharlesAtlasSuperpower: His Renkin, Silver Skin, only helps his defense, all his earth shattering punches and acrobatics come from hard work and dedication.
* TheCharmer: Bravo Secret Art! Captain Bravo...Kiss!
* CollaredByFashion: When wearing his coat.
* [[spoiler:FaceHeelTurn: It doesn't last forever though]].
* TheGoodCaptain
* GoodOldFisticuffs: His Busou Renkin is armor, so he just kicks ass with his bare hands.
* [[spoiler:HeroicSacrifice: It may not have been needed to a BigDamnHeroes, but it was still very cute.]]
* LargeHam: Very, very hammy.
-->[[GratuitousEnglish YES! I AM!]]
* MrFanservice: Ripped, handsome, kind, charming, energetic, badass and protective of children.
* MyGreatestFailure: The attack on Tokiko's school, of which she was the SoleSurvivor.
* NiceHat: His silver hat.
* NighInvulnerable: He has a regenerating invincible coat.
* PapaWolf
* RatedMForManly
* RuleOfCool: His main creed. "[[CatchPhrase Why? 'Cause it's cooler that way]]!"
* StoneWall: He tries to compensate for having a purely defensive Busou Renkin with impressive barehanded-combat skills, but the fact remains that he's better at taking hits than dishing them out.
* WrestlerInAllOfUs: Considering that he specializes in unarmed close combat, it's not that surprising that he pulls off some wrestling moves, like an Octopus Stretch and an Argentinean Backbreaker.

[[folder:Captain Hiwatari]]
-->Voiced by: Creator/TomokazuSeki (JP), Creator/KyleHebert (EN)

Another Alchemist Warrior, who's called in to deal with [[BigBad Victor]] and [[spoiler: Kazuki's black Kakugane]], [[JerkAss total dick]]. [[PlayingWithFire Likes fire]].
* BloodKnight: Loves burning people, doesn't matter who.
* ColonelKilgore
* DrillSergeantNasty: Loves calling his minions ladies.
* FreudianExcuse: It's doubtful he was ever nice, but his BloodKnight and GeneralRipper tendencies really came to the fore after the massacre in Tokiko's school, much like with Captain Bravo. Both were deeply affected by that event: Bravo became near suicidal in his desire to protect others, Hiwatari just went "Screw this, the world is insane anyway, we might as well be crazy, too".
* GeneralRipper
* HotBlooded
* MyGreatestFailure: Like Captain Bravo, he was deeply ashamed of the massacre in Tokiko's school.
* NukeEm: His Busou Renkin, Blaze of Glory, is a napalm bomb.
* SuperPowerLottery: Oh god yes. Flight, regeneration and [[PlayingWithFire fire control]] are vast understatements of his ability.
* TokenEvilTeammate: Seems the worst out of all the Alchemist Warriors. His friendship with Bravo is genuine, though.
* WalkingShirtlessScene: With a {{Sarashi}}.

[[folder:Gouta Nakamura]]
-->Voiced by: Creator/ShinjiKawada (JP), Creator/LiamOBrien (EN)

A rookie Alchemist Warrior that was apprenticed by Tokiko. Fell in love with her when she gave him a reason to become an Alchemist Warrior. Strongly dislikes Kazuki at first, not just because of jealousy, but also because Tokiko puts herself at danger to help him. Uses Gear Chakram.
%% * FragileSpeedster: Can use his Renkin, Motor Gear, as roller-skates for maximum speed.
* GuestStarPartyMember: Only appears in the second part of the series, but is one of the main characters from then on.
* HeelFaceTurn: Decides to quit hunting down Kazuki for Tokiko's sake. This does progress into an actual friendship, even if not an easy one.
* HotForTeacher: Tokiko was his mentor.
* IJustWantMyBelovedToBeHappy: Eventually. It's noted that he actually becomes more mature when he stops dwelling on his feelings for Tokiko.
* WeakButSkilled: Takes down a lot of people with his relatively weak abilities using his brains and speed.
* WrongGenreSavvy: Thinks that he's the RomanticFalseLead and [[BettyAndVeronica Veronica]] between Kazuki and Tokiko, but he really isn't; Tokiko does like him, but not in any romantic way, while Kazuki is completely oblivious to their "rivalry" and talks about what great friends they are. Kind of veers into AllLoveIsUnrequited territory.

[[folder:Victor Powered]]
-->Voiced by: Creator/RikiyaKoyama (JP), Creator/YuriLowenthal (EN)

An ancient alchemist who was given a Black Kakugane in place of his heart in order for him to survive. This [[WithGreatPowerComesGreatInsanity granted him amazing strength, durability, and the abilities of flight and regeneration, but also drove him mad.]] Uses an axe.

[[spoiler: After LXE is defeated, Moon Face is put into custody by the Alchemy Warriors, and later sent to the Moon with Victor and the other homunculi.]] Moon Face joined the LXE a hundred years before the start of the series, when he came from Russia to Japan for reasons unknown.
* DoppelgangerAttack: The ability of his Buso Renkin, Sattelite 30.

* MeaningfulName:
** His head looks like a moon his name is also a play on "moon phase", which refers to his Buso Renkin's ability to create a duplicate representing every phase of the moon during a month.

* NamesTheSame: He is ''not'' the Creator/EnidBlyton character.

[[folder:Dr. Butterfly]]
-->Voiced by: Katsumi Chou (JP), David Lodge (EN)

Around a century ago back when Bakushaku Chouno was a normal human, new sciences and technologies were flooding in from all over the world. One of them was alchemy which most people dismissed as charlatanry, however Bakushaku sensed there was more to it and so he began to delve into its mysteries. To his disappointment he found that there were limits to how far he could go on his own. His studies had consumed a fortune and years of his life went by until he discovered the homunculi and the Kakugane which led him to a dead end. However, not long after he met Victor Powered, a traitor of the alchemist warriors, the two then joined forces. Victor was severely injured so in exchange for his knowledge of alchemy, Bakushaku promised to heal him when he had finished his research.

At some point later Bakushaku became a humanoid homunculus and discarded his identity, now calling himself Dr. Butterfly. He then went on to found the L.X.E.
