Characters / Busou Renkin

A list of characters and character-related tropes from Busou Renkin!

Kazuki Muto

Voiced by: Jun Fukuyama (JP), Steve Staley (EN)

The Hero 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.

Tokiko Tsumura

Voiced by: Ryoka Yuzuki (JP), Tara Platt (EN)

Kazuki's savior and lancer, Tokiko introduces him into the world of alchemy and saves his life by giving Kazuki a Kakugane. Total Badass.
  • Action Girl
  • Action Girlfriend
  • Anti-Hero: She's willing to Shoot the Dog.
  • Badass: Even more than The Hero, which is saying something.
  • Battle Couple: With Kazuki.
  • Belated Backstory: Her origin is not revealed in the manga until the final issue, where it's revealed 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.
  • Boring but Practical: Other alchemists get flashy Stock Superpowers. 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.
  • Catch Phrase: Often yells something about her opponents' guts, such as her intentions to rip them out, splatter them etc; also On The Next Episode Of Catchphrase
  • Combat Pragmatist: She doesn't really fight fair.
  • Deadpan Snarker: Whenever she isn't fighting.
  • Defrosting Ice Queen: She started out as somewhat cold to Kazuki, but starts growing attached to him over time and finally falls in love with him.
  • Don't Fear the Reaper: Her Busou Renkin's sub-name is Death Scythe, she's pretty to boot.
  • Even the Girls Want Her: Well Mahiro does anyway.
  • Fantastic Racism: Really, really hates homunculi or anybody who would help them.
  • Four Is Death: Her Busou Renkin, "Busou Renkin of the Death Scythe: Valkyrie Skirt," has four blades.
  • Going Commando: She doesn't wear a bra, not like she needs one, but was it necessary to show her undress?
  • Good Scars, Evil Scars: It's noticeable, representing her status as an Anti-Hero, but it's even, showing her inherently good nature.
  • The Hunter: Was the Sole Survivor of a homunculi massacre, which explains her ruthless attitude toward them.
  • Improbable Weapon User: Even more then Kazuki, it's four scythes on the end of robot arms attached at her thighs.
  • The Lancer
  • Magic Skirt
  • Ms. Fanservice: Her clothes are always getting ripped up and she reluctantly wore a bikini in one episode.
    • 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 Shots.
  • Official Couple: With Kazuki.
  • Perpetual Frowner
  • Red Oni, Blue Oni: Blue Oni to Kazuki's Red Oni. Though she gets quite excited during battle.
  • Rescue Introduction: Subverted. Kazuki thought she was in danger of being attacked by Homunculus Mita, but she actually was just luring it into a trap.
  • Scars Are Forever: The scar across her nose that she got from a homunculus attack. Actually, it could have been healed, but she wanted to keep it.
  • Sci-Fi Bob Haircut
  • Sexy Mentor
  • Sole Survivor: Of a homunculus attack on her school. She was rescued by Captain Bravo.
  • Spider Limbs: Her Valkyrie Skirt.
  • Sugar and Ice Personality: Specially at the beginning.
  • Transfer Student Uniforms: 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.
  • Trauma-Induced Amnesia: 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.
  • Weak, but Skilled: 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.
  • Zettai Ryouiki: Grade B-.


Voiced by: Mitsuaki Madono (JP), Spike Spencer (EN)

Once known as Koushaku Chouno, a sickly loner despised by his family, he became a homunculus and a massive ham as well.

Tropes associated with Captain Bravo

Captain Hiwatari

Voiced by: Tomokazu Seki (JP), Kyle Hebert (EN)

Another Alchemist Warrior, who's called in to deal with Victor and Kazuki's black Kakugane, total dick. Likes fire.

Gouta Nakamura

Voiced by: Shinji Kawada (JP), Liam O'Brien (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.
  • Guest Star Party Member: Only appears in the second part of the series, but is one of the main characters from then on.
  • Heel–Face Turn: Decides to quit hunting down Kazuki for Tokiko's sake. This does progress into an actual friendship, even if not an easy one.
  • Hot for Teacher: Tokiko was his mentor.
  • Ignored Rival: Thinks he can take Tokiko away from Kazuki. Kazuki doesn't lift a finger to stop him - he doesn't have to.
  • I Just Want My Beloved to Be Happy: Eventually. It's noted that he actually becomes more mature when he stops dwelling on his feelings for Tokiko.
  • Jerk with a Heart of Gold: I understand you think Kazuki is stupid (and he really is), but do you need to be such a gigantic prick to him?
  • Weak, but Skilled: Takes down a lot of people with his relatively weak abilities using his brains and speed.
  • Wrong Genre Savvy: Thinks that he's the Romantic False Lead and 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 All Love Is Unrequited territory.

Victor Powered

Voiced by: Rikiya Koyama (JP), Yuri Lowenthal (EN)

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

Moon Face

Voiced by: Tomokazu Seki (JP), Christopher Corey Smith (EN)

Originally named Lunare Nikolaev, Moon Face is a homunculus with a moon-shaped head and a higher-up of LXE He is depicted as constantly cheerful, rarely seen without smiling, and he uses the catch phrase "Moon~" whenever possible. 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.

  • Doppelgänger Attack: The ability of his Buso Renkin, Sattelite 30.
  • Hero Killer
  • Meaningful Name: 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.
    • His original name also counts, being similar to "lunar", meaning "of the moon".
  • Name's the Same: He is not the Enid Blyton character.
  • Shout-Out: Watsuki stated that he got the idea of Satellite 30 from the character Agent Smith from The Matrix Reloaded.
  • Verbal Tic: "Moo~n!"

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.
