Main Cast

    The Takamiya Brothers 

Teppei Takamiya
Voiced by: Nobuyuki Hiyama, Yoshiko Kamei [Child] (Japanese), Eric Vale, Kristen McGuire [Child] (English)

The protagonist, he lives on a private island north of Hokkaido called Kamui Island with his brother Kotaro. Short after sending off his brother Kotaro to study overseas, he found an injured lady named Karen, who later became his trainer to prepare him for a tough battle in case something happens to his intelligent brother.

  • Alliterative Name: His initials starts with "T."
  • Big Brother Worship: Teppei looks up to his brother Kotaro alot, and would mention how he couldn't outsmart his intelligence.
  • Big Ol' Eyebrows: Well, he certainly has the thickest of all the main cast.
  • Came Back Strong: With the aid of Hokuto, X and Teppei underwent a Mid-Season Upgrade after the former was reduced to scrap, with Teppei gruelingly injured.
  • The Chosen One: At the very beginning, Teppei's only mission was to head inside of the Empire to get his brother outta there, but by the moment Teppei awakens his true form, he was given literally no choice but to save humanity.
  • Color Motif: Stationed militant, Camilla judges people by color. He originally asked Teppei what his color motif was, who obviously has no clue in what he was talking about. After their battle, Camilla concluded Teppei as "A man pure as white, yet not completely white, with compassion red as fire, yet not truly red; just like the sun, dazzling to everyone's eyes."
  • Coming-of-Age Story: The story as a whole can be seen as Teppei's development towards mental and physical maturity.
  • The Confidant: Of Demon General, Meimu. The then dying Meimu initially wanted Teppei to help him pass his confession to Hokuto, his little brother, in regards to the truth behind the nuclear incident in which Hokuto suffers from, but Teppei decided not to reveal it to Hokuto, even when Hokuto clearly understands that Teppei is hiding information from him, Teppei just won't spit it out, because he felt that it was unnecessary to break the bond that they finally patched up after all their years of separation.
  • Declaration of Protection: One of Teppei's major motifs, indicating he would move heaven and hell to protect his loved ones; in this case, his brother. Kurumada specifically wrote his Image Song with this theme.
  • Expy: As part of the Masami Kurumada protagonist family, he's destined to follow the bloodline of Ryuji Takane, and the Legendary Seiya.
  • Friend to All Living Things / Fluffy Tamer: It was implied that he could befriend and cuddle a full grown WILD BEAR at the age of roughly 7, not to mention Teppei also Speaks Fluent Animal given he understood the bear's situation as being pregnant and wishes to have some fish so that she can give birth to a healthy cub.
  • Grappling-Hook Pistol: One of the main funtions of Teppei's Messiah Fist. His "Shining Knuckle" attack is the power enhanced version of this function.
  • Gratuitous English: "X! Omae wa ore no baadii da!"
  • The Hero
    • Action Hero: He'll be willing to go to great lengths body-guarding his non-action brother Kotaro.
    • Celibate Hero: Camilla and Demon General Salome both had toyed with Teppei's various desires,note  and seduced him with their spells during their battles with him. But Teppei, while still under their spells, overcame their seductions out of sheer will and was able to talk to them with a cool-headed straight face. Teppei is not by any means, saying he absolutely won't share his feelings or desires with others, but as in when it comes to the things that he needs to solve first, he will get through those things first.
    Teppei: "How dare a man have his heart be willingly controlled by others? A true man has all the responsibilities to control his feelings and desires with his own conscience."
  • Hotblooded
  • Hunk: Teppei's proven to be manly and pretty at the same time. Thanks to the anime character designer standing true to the manga art style, viewers can noticably tell how Kurumada designed Teppei to be a lot more handsome than his predecessors.
  • Kiai: Earned one in their pachinko game.
  • Kid Has a Point: While all Machine Empire militants were swearing their loyalty towards their Emperor and praise him as their god and claiming him as their savior to mankind, Teppei keeps pounding each and every one of them with questions along the lines of: "Dude! If your Emperor is so righteous, why did he order a massacre on innocent people just to abduct one person?!" until someone's conscience kicked in some sense. The Spirit Generals certainly did.
  • Kill It with Fire: Teppei's initial Finishing Move in the anime is "Break On", a pillar of flames. He ditches that later on.
  • Light Is Good: Teppei's theme revolves around being The Light and the charismatic influence towards the people he encounters, along with his characteristics below:
  • Meaningful Name: His first name means, "Iron Soldier," while his last name means "High Palace," in which can also be an extension for "Heaven." Combine them, his full name literally means "The Iron Soldier from the High Palace."
  • Mid-Season Upgrade: The anime and Kurumada's illustrations were not completely stable on this, but overall, Teppei's Battle Gear armor went from silicone-ish white to cream-yellow. And no, Battle Gears were not made from metal materials.
  • Mr. Fanservice: When he was recovering during X's Mid-Season Upgrade, Hokuto had already stripped off his clothes leaving himself completely exposed wearing only his boxer briefs note  in the manga, but the anime took it further in taking out his boxers all together, giving him Scenery Censor and Lens Flare Censor from the incubator he sleeps in.
    • Female Gaze: Unlike his expy who has armor protecting their crotch section, Teppei's battle gear doesn't. Therefore the audience were quick to notice his cute bun-shot in his first Transformation Sequence, and were displeased the animation production took out that eye-candy for his upgraded sequence.
  • Power Fist: His weapon, The Messiah Fist gauntlet is a hand power enhancer, GPS, and wire weapon that has marble hooks attached to the front of each wire. Teppei can control the strength of his wires to be either penetrating floss, or to simply act as a whip.
  • Rapid-Fire Fisticuffs: Also earned one in their pachinko game along with his Kiai.
  • Sacred First Kiss: In the manga, Teppei's kiss was stolen by a guy, and he was noticeably squicked by it.
  • Shout-Out: Teppei's name is most likely a direct tribute to the lead character, "Teppei Uesugi" from manga, Ore wa Teppei note  created by Kurumada's idol manga artist, Tetsuya Chiba, who co-created Tomorrow's Joe.
  • Smarter Than You Look: It's quite hard to pinpoint your true intelligence when you're competing against an academically Born Winner older brother. Therefore, Teppei tends to feel he's Book Dumb, and opts to mold himself to become the athletic performer of the Sibling Team rather than improving his academics. However, it was because he was raised with a big brother stuffing him with abnormal amounts of technological knowledge since birth, that he unknowingly blinded himself to the fact, through a few subtle implications within the story, that he actually did mastered all the teachings Karen had passed down to him, including the Machine Empire's 300 years in global advanced Mechanical Engineering knowledge and skill set.
    • One scene in particular caught a clear glimpse of Teppei's intellect, where he just looked at X for a spit-second while X barely walked 3 steps on the ground to know X couldn't perform well due to X's leg joint being loose. Hence, that's how X ended up with Teppei's bandanna tied to his leg.
  • Student and Master Team: With Karen.
  • Suicidal Overconfidence: Teppei suffers from this early on. It takes X essentially dying for him to start realizing he can't act stupid, if only for the sake of others.
  • Super Strength: He can break a giant solid rock in the size of a mammoth into two...with one bare fist. His grip and fist power goes Up to Eleven when he equips his Messiah Fist gauntlet.
  • Tender Tears: People tend to mistake Teppei's constant shed of tears as Manly Tears due to his Kurumada protagonist status, but rather he is this because he's actually a pretty sensitive guy. Teppei cries over almost anything from Kotaro leaving to study overseas, his pet pony being stabbed to death by Metalface, to Juggler's death, and especially noticeable when he cries upon seeing Amigo's corpse in the anime.
  • When He Smiles: Teppei rarely has chances to genuinely smile. So when he does, it will be special to everyone surrounding him. Said moment may or may not Cue the Sun.
  • Younger Than They Look: Compare to his expys, or even besides his own older brother, he's noticeably more mature and masculine-looking. Yet he's only 14.

Kotaro Takamiya
Voiced by: Nozomu Sasaki (Japanese), Josh Grelle (English)

Teppei's older brother and Deuteragonist of the series. He's a 16 year-old Professor in Robotics who upon releasing a thesis in AI Robot Technology, got kidnapped by the Machine Empire.

  • Action Survivor: He's just a certified scientist/engineer who has no martial arts, nor military training whatsoever. Therefore he has to greatly rely on his own intellect, survival instincts, and the might of his brother's comrades and or anyone he befriends around himself to survive his whole abduction tale.
  • Big Brother Instinct: Even when he's been captured, a part of his mind has been thinking about Teppei's safety.
  • Child Prodigy: He solved complicated formulas at the age of 7, and was enrolled into a Berlin university at the age of 11. Aging on to Teen Genius when the storyline started.
  • Cool Big Brother: Of Teppei, he builds a really cool high-tech secret hideout inside their backyard tree and allows Teppei to freely play in it.
  • Defiant Captive: The perk for him being a young guy, and the most recent captive amongst all other scientists who were abducted before him. But Kotaro is exceptionally more defiant since he knew his brother is on the road to rescue him.
  • Determinator: Just as his little brother is determined to rescue him no matter the circumstance, Kotaro does his part in trusting his brother to rescue him; giving his all to survive Underhell, and come up with the formula to defeat B't Raffaello.
  • Distressed Dude: Got kidnapped by the Machine Empire to force him to work for them in finding the resolution on how to stop the ever growing horror, B't Raphaello. He refuses, and was banished to the Underground doing slave labor. But that didn't stop him in thinking of ways to get out of that place.
  • Doing Research: His main mission in story, he needs to find the math solution to destroy B't Raffaello before it eats the Earth up.
  • Expy: He's pretty much the Prince Marg to his little brother, Teppei. Only that Kotaro's more than 1000 times smarter than that expy of his.
    • Kurumada series-wise, most fans figured he's a mix between Andromeda Shun and Aries Mu.
  • Hard Work Hardly Works: A tiny episode of his childhood with Teppei implies how Kotaro originally designed a pair of fishing rods meant for Teppei and himself to fish "more effortlessly" than using the adult rods. But in the end, Kotaro barely had any catches, while Teppei, indeed effortlessly, emptied the entire river picking off over 2 fishes per second, overflowing buckets full with fish. While at the same time, giving Kotaro all the credit for making this awesome rod believing it was the rod, and Kotaro's genius, that's super.
  • Meaningful Name: The first character of his name in Kotaro, means "Steel," in which his nerves can back it up. Combined with Teppei's first character, they are "Steel and Iron".
  • Nerves of Steel: He sure damn is. He didn't lose his cool nor blink an eye when being neck-wired right on the first episode.
  • Non-Action Guy: Though he generously showed us how to write formulas on the ground in a hotblooded mindset.
  • Odd Couple: Ron ends up aiding him for the most part in the manga.
  • Playful Hacker
  • Power of Trust: Kotaro's major motif. He's a man who greatly trusts in his brother's talents, abilities, and his word in fulfilling the promises towards those who he swore to. Kotaro himself is also a man who executes his words with extreme caution and weight, therefore, every opinion he makes will always be backed with his full attestation. Like Teppei, Kurumada also wrote his Image Song with this theme.
  • Rapid-Fire Typing: Whenever he can get his hands on a computer to do research, this is how he will perform.
  • Teen Genius: He released a study proven the ability to create biologically intellectual robots in a press conference at the Machine Expo at the age of 16. Not to mention he already obtained his Ph.D long before that.
  • Telepathy: In the final chapter of the manga, Kotaro's conscience was thoroughly in sync with his brother to the point where he was able to perform telepathy to Teppei across space; signaling Teppei to not concern of him being in the way, and just give B't Raffaello the final blow.

    The Four Spirit Generals 

Voiced by: Megumi Ogata (Japanese), Morgan Garrett (English)

General of the West, former Donor of B't X and current Donor of B't Shadow X. She escaped from the Machine Empire upon understanding their country's plan in destroying mankind.

  • Action Girl
  • Badass Normal: Can destroy an entire Ryukaon squad on foot and beat Metalface in hand-to-hand combat. Not to mention that she also went on a few rounds with Raphaello on foot.

  • 11th-Hour Ranger: Karen eventually went back into action with Shadow X as her B't.
  • Fighting with Chucks: Her weapon of choice, and can flash electricity with it.
  • Gadgeteer Genius: Taking only the core parts of the B't Ryukaon scraps that she defeated on Kamui Island, the rest of the materials that she used to build Shadow X was mostly out of...god knows what they were.
    • She's also the one who created Teppei's Messiah Fist out of B't Raffaello's cell.
  • Morality Pet: Of Metalface.
  • Motherly Scientist: She's pretty much one of the only few Donors who pampers their B'ts like their own children, X and Shadow sure are spoiled.
  • Seeker Archetype: Her major motif. After being jailed and fled for questioning her authorities regarding B't Raffaello and the policies her government, Karen sets herself on the quest to search for answers and the key elements to take down B't Raffaello. Which in her case, scouted Teppei and found the key element—"Piece of the Sun." Kurumada wrote her Image Song with this theme.
  • Sexy Mentor: Of Teppei.
  • Stripperiffic: Whether Teppei is around her or not, she doesn't mind strolling around either half or completely naked.

The General of the North and Donor of B't Max, a General Medical Physician who is also a Master Engineer of B'ts. His birth year is roughly late 2011 to 2012, since it's revealed he was 9 years-old during the summer of 2021.

    The Five Main B'ts 

X the Kirin
Voiced by: Jin Horikawa (Japanese), Jeremy Inman (English)

The title name holder and Supporting Protagonist of the series. A Male B't manufactured by the Machine Empire in the form of the Chinese mythological animal, Kirin. He has a prideful tough-guy personality, originally was programed to swear loyalty towards his original Donor, Karen the General of the West Wing of the Machine Empire. Upon taking Karen out of the country for exile, his function died out midway and was taken back to the Empire to be disposed. 5 years later, he was awakened again from sensing Karen's blood reentering his body, only to find himself dumbfounded to see that the person who gave him Karen's blood was through a boy name Teppei. Legend says that when a Kirin descends from Heaven, the land shall be saved from evil.

Shadow X the Kirin
Voiced by: Emi Shinohara (Japanese), Marissa Lenti (English)

A Female B't manufactured by Karen herself in the form of the Chinese mythological animal, Kirin. Karen has been slowly putting her together during the 5 years of her stay at Kamui Island. At first Shadow was uncontrollable, and often went berserk in flying out of hand trying to head to wherever X was located. It wasn't until Teppei dragged her to Hokuto to be stabilized that she was able to create a personality of her own.

  • Annoying Younger Sibling: By sharing the same blood from Karen, she is legitimately X's little sister. In the manga, she's pretty hyper and excited upon meeting her brother for the first time after her fine-tune, yet the stiff-brained X doesn't really know how to handle her lively spirit.
  • Canon Immigrant: Shadow was a filler character who was originally planned to be nurtured through the anime. But TMS Entertainment found themselves Screwed by the Network on short notice and couldn’t develope her character in time. Kurumada saved both TMS and his dear work by officially making Shadow canon within the manga.
  • Cool Mechanical Kirin: And she has wings too!
  • The Cutie: She calls X "oniichan" with an affectionate rub on the neck in the anime, and was shown Up to Eleven throwing major squees in the manga.
  • Dark Is Not Evil: She may have a black coating, but that personality of hers totally throws the term "evil" out of the equation.
  • Distaff Counterpart: Of X, she's made from spare parts of various B't Ryukaons and other materials.
  • Fragile Speedster: She's shown to have exceptional speed in the manga.
  • Genki Girl: She literally spins around in circles upon meeting X for the first time after her fine-tune.
  • Plucky Girl: It's pretty obvious that she's one fearless little gal when she had her first show-down with B't Madonna in the manga, Shadow even had fun driving Madonna crazy with her speed skills.
  • Replacement Goldfish: Karen created Shadow X to replace X as her B't in case Karen ever confirmed X was impossible to repair, and needed to face off with The Machine Empire. Blessed X was alive and willingly teamed up with her pupil, otherwise Shadow might have ended up with either no owner, or eventually paired with Teppei.
  • Token Mini-Moe: Despite her size, in a B't team full of stoics, she is definitely this. Plus, she's the youngest to be born anyway.

Je t'aime the Phoenix
Voiced by: Asako Dodo (Japanese), Tia Ballard (English)

A Female B't manufactured by the Machine Empire in the form of the Chinese mythological animal, Phoenix. She has a prideful personality and can be a bit inflexible with people.

Raidou the Dragon
Voiced by: Ryuji Mizuno (Japanese), Marcus D. Stimac (English)

A Male B't manufactured by the Machine Empire in the form of the Chinese mythological animal, Dragon. His personality is mostly stoic, and obeys Ron's orders in the most absolute fashion.

Max the Turtle
Voiced by: Gara Takashima (Japanese), Clarine Harp (English)

A Female B't manufactured by the Machine Empire in the form of the Chinese mythological animal, Turtle. She has a serious but witty personality, and would be willing to talk to other people beside her Donor Hokuto. She could get emotional from time to time.

The 13 Stationed Militants

Upon thousands of stationed military posts The Machine Empire placed around its country for defense, starting to where Fou's station was located, these 13 posts marks the shortest lineup route Teppei has to go through in order to enter The Tower. Based on Fou's observation, most stationed guards are way too prideful, and achievement-oriented to bother with team play, therefore, each militant would most likely go one-on-one with their invaders and not report their failures to other posts if they were to lose in battle.

B't: Krubi the Earthworm (VA: Yuichi Nagashima)


Voiced by: Kappei Yamaguchi (Japanese), Meli Grant (English)
B't: Mirage the Butterfly (VA: Maya Okamoto)

The Death God

Voiced by: Mitsuru Miyamoto
B't: Unnamed Bat B't

  • Dark Is Evil: The Death God and his Bat B't are a very straight example.
  • Cybernetics Eat Your Soul: Invoked. He got hit so bad with it that the Death God is not capable of uttering a word. Goes in outright Tear Jerker territory when you see how his area was before, and what it has turned into.
  • Cue the Sun: Played straight on two counts. Night falls on his area as Teppei starts fighting him, and he gets his Heroic Second Wind just as the sun rises, channeling the Power of the Sun for the first time.
  • Four Is Death: The fourth opponent to Teppei and X, and a Death God.
  • Wake-Up Call Boss: This opponent actually puts Teppei and X on the ropes, and this is where Teppei learns he has to treat X as more than just a tool to bring out his power.


Voiced by: Hideyuki Umezu (Japanese), Alejandro Saab (English)
B't: Cans the Crab (VA: Chafurin)

  • Curb-Stomp Battle: Gets stomped by a passing Teppei who has just awakened X's true power.
  • Dirty Coward: He lets Foh through because he knows he has not a snowball chance in hell against him, even though he is a traitor.

The Three Dark Knights: Lai, Leon, and Mila

Voiced by: Sho Hayami [Lai], Kouji Ishii [Leon], Takehito Koyasu [Mila]
B't: Falcons (VA: Kenichi Ono)

  • Expy: Of those three guys from Saint Seiya, the three Silver Saints (Canis Major Sirius, Musca Dio, Hercules Algethi) ganging up to kill Seiya before getting killed via Curb-Stomp Battle.
  • Filler: The Dark Knights themselves were not filler villains to the storyline, but their fight was expanded to 3 episodes to serve as foreshadow to Teppei's connection with the Sun, and the potential he has.


Voiced by: Mitsuo Senda
B't: Sabanna the Mermecolion (VA: Tetsuo Kanao)

  • Can't Catch Up: Invoked by Hokuto on him, just as Teppei curbstomped him, saying normal guardians would not be a problem anymore for Teppei.
  • Laser Hallway: His technique looks like this. He can actually pin down a bulky B't like Max, but this is ineffective against a repaired and upgraded B't X.

    The Seven Demon Generals 
The most elite group of militants The Machine Empire has to its possession. Normally, these Generals are to serve as bodyguards towards The Machine Emperor himself, but Teppei's invasion up to the 6th base, along with Fou and Hokuto's betrayal alert up in the air was deemed a threat big enough to have them replace the guards of the remaining 7 posts Teppei has to pass to enter The Tower.


Voiced by: Jurota Kosugi (Japanese), Chris Arnott (English)

The first of the Demon Generals to appear in the anime. He claims to be the Prince of Darkness, contrasting his opponent, Teppei, who represents The Light.

  • Ermine Cape Effect: Proclaiming as the Prince of Darkness, Myslim was dressed more on the practical dandy side with a frilly pink blouse paired with a red long coat. Still fancier than other fellow antagonists Teppei faced though.
  • Green and Mean: He has long seaweed-shade green hair, with an unhealthy greenish complexion.
  • Hydra Problem: His B't Lanenia is based on the mythological animal Hydra, with nine heads and can regrow if one head is damaged.
  • Medusa: Rare male example. His powers revolves around the motif of Medusa, armed with a gauntlet call "Viper Whip", which has mechanical snakes mounted to the fingers to shoot out venom that can weather-down whatever it contacts into sand.
  • Red Eyes, Take Warning
  • Taken for Granite: What he can invoke on his opponents. He tries this on Teppei, who is VERY lucky to have an upgraded X to protect him.
  • Wake-Up Call Boss: Serves as a preview of what the Demon Generals can do, and how they should not be taken lightly.


Voiced by: Toshihiko Seki (Japanese), David Matranga (English)

Second of Demon Generals to appear in the anime. He was Foh's childhood friend, and seems to hold some kind of grudge against Foh. And the two of them faced-off in a private battle.


The third and sole female Demon General that Teppei faced in the path towards the Empire Tower. She can control the minds and actions of others when they hear a music piece that she performs a dance to. Her name and character was based on the seductiveness from The Bible who triggered the death of John the Baptist.[2]


The fourth Demon General blocking Teppei from the Empire Tower, he is obsessed with beauty, and has a cybernetic body made of precious stones. Sapphire encased Max in a precious stone, who has both Hokuto and Foh onboard, leaving Teppei the only person to deal with him.

Dr. Poe


Voiced by: Shin-ichiro Miki (Japanese), Stephen Fu (English)

The third and last out of seven generals to appear in the anime. In the manga, he's the 6th person to appear.


The last of the Demon Generals to appear. A philosopher, he originally was going to face-off with Teppei one-on-one since Teppei was the first to arrive at his stationed post, but Foh offered to take on Gai in Teppei's place in order to let Teppei enter the Empire Tower to search for his brother as soon as he can.
  • Physical God: In the manga, Gai technically doesn't exist, is immortal, can make an infinite number of copies of himself, and has possibly unlimited firepower.
  • The Power of Love: The only reason Foh was able to defeat Gai. note 
  • Nietzsche Wannabe: Gai is the philosopher of the empire, but also a firm believer that Humans Are the Real Monsters.

Voiced by: Naoki Tatsuta (Japanese), Justin Briner (English)

  • Must Make Amends: Marcelo does a lot of very, very stupid and amoral things, ultimately pushing him to strive to do everything he can to help Kotaro when that time comes. In the anime, his knowledge of the tower's layout is utterly crucial.
  • Oh, Crap!: Gets a very nasty serving of this when Aramis tells him that Pr. Kotaro is to be well cared for, as he will eventually become a very important person for the Empire. He just pretty much had just sent him to die MINUTES before.
  • Villainous Demotivator: Towards anyone whose ranks are lower than him in Underhell, and that's everyone down there.


Voiced by: Shinpachi Tsuji (Japanese), Chris Rager (English)

  • Mistreatment-Induced Betrayal: He left Marcelo's side without even blinking an eye.
  • The Power of Friendship
  • Shock Collar: His Cybernetic body parts were poorly done, which makes him suffer from extreme pain.
  • A Taste of the Lash: Marcelo whips Amigo whenever he doesn't obey his commands.
  • You Shall Not Pass!: In the anime, Amigo guards over one of The Tower's computer room where Kotaro's attempting to hack in. When he's near his death, Amigo wraps his arms around the metal pipes surrounding the door with his body, which stalls the enemy mooks long enough for Teppei to arrive and finish them off.

Dr. Lisa Maria Stein

  • Ascended Extra: She's an anime-original character, yet she's got bigger supporting status than original manga scientist characters.


Voiced by: Fujiko Takimoto (Japanese), Amber Lee Connors (English)

  • Ambiguously Brown: He's got a pretty tanned complexion, but it's justified that he's a Child Soldier who's stationed at a dessert area.
  • Child Soldier: Implied to be forced into unauthorized military labor.
  • Child Prodigy: Of robotic engineering. Gaku showcased his talents in building not-too-shabby Macross Missile Massacre robots out of scrap metal, but it's no way in comparison to the level of B'ts, and he doesn't have the resources to refine his talents. But Gaku is an example on how much advanced the common civilians of The Machine Empire are in terms of technology and engineering education.

The Machine Emperor

    Misha & Nasha 
A pair of Half-Identical Twins who serve as their Emperor's substitute ruler of their country. They have complete authority as their Emperor in setting the law of the land, determining the life and deaths of their countrymen, and to assign the duties of their military base.

In General

  • Creepy Children: Both Misha and Nasha are 300 year-old children who stopped aging due to their Emperor granting them cybernetic bodies. While Nasha is shown to be mentally mature, Misha is psychotically childish.


Voiced by: Ai Orikasa (Japanese) , Alison Viktorin (English)

The older brother of the twins. He abides by The Emperor's orders in the most absolute fashion, and rules his country with an iron fist. If anyone questions anything in regards to his authority and The Empire's orders, he would gleefully execute them on spot.


Voiced by: Kyoko Hikami (Japanese), Natalie Hoover (English)

The younger sister of the twins. She is merciful and compassionate to her people compared to her brother, therefore, she would do all she can to veto her brother's immoral decisions. Nasha has poor health due to her cybernetic body, therefore, there's is little she can do to prevent her brother to place harm on civilians.

     The Emperor 
The Emperor who founded The Machine Empire. He was a scientist who was already well over 200 years old when he met Misha during The Renaissance on his journey actively seeking ways to make his thesis: "Man-Made Lifeform," into reality.
  • Exposition of Immortality: He lets Misha in on his ambitions and secrets to immortality when he picked Misha and Nasha up from The Renaissance period.
  • The Faceless: We do not see the Machine Emperor in "person" until the final volume, and never once in the anime. The final volume of the manga eventually reveals his physical body has been long dead, but his brain is instead enlarged and kept alive through machine technology, waiting to be placed into B't Raffaello, which was intended to become his "new body."
  • Godhood Seeker: The Machine Emperor is an example who is in reach to A God Am I as a human scientist originally wanting to contribute to society with his gifts in multi-fields of technology breakthroughs. But due to years of being persecuted, he resolved in experimenting on himself to pursue the highest personal, and political status power possible to prove divinity is attainable.
  • Immortality Seeker: Amongst his vast bio-engineering creations, his greatest ambition was to create an immortal life-form of himself. Via merging with B't Raffaello.
  • Insufferable Genius
