Yuga Mikado

Dragon World, Katana World, Magic World

Voiced By: Takumi Mano (JP), Griffin Kingston (EN)

The Ace of Games and son of Gao and Paruko. Yuga enjoys playing and creating all sorts of games and regularly posts videos online of himself giving them a try, acting as one part of Ran-Ga Channel. Yuga begins the series having never actually played Buddyfight before, but upon opening up his first pack of cards obtains his buddy: Deity of Combat, Gargantua Dragon. Additionally, he has inherited the Gargantua Punisher, which his buddy evolved into Deity Gargantua Punisher.

Yuga plays a Dragon World deck centered around the Deity Dragon Tribe attribute and focuses on using Gargantua Dragon's G.Evo ability to it's fullest. He later plays a Katana World deck focusing not only on his Dragon World deck's G-EVO, but also Ninja Arts and ninja-themed versions of his Deity Dragon Tribe monsters. Further into the series, he also gains a Magic World deck which combines the playstyle of the Deity Dragon Tribe with the focus on spells present in that world.


  • The Ace: At least when it comes to games it seems, the kid is constantly inventing and trying out new games.
  • Amusing Injuries: In the manga, it's one of his defining traits. Ironically enough, never seems to suffer them in the anime
  • BFS: His impact card, Deity Gargantua Punisher.
  • Butt-Monkey: Constantly getting beat up in the manga.
  • Childhood Friend: With Miko.
  • Constantly Curious: The moment Yuga meets Garga he starts asking the dragon a ton of questions, much to the latter's annoyance.
  • Contrasting Sequel Protagonist: Just like his dad Gao he's a prodigy in Buddyfighting. Whereas Gao was Hot-Blooded and much more instinctual, Yuga is more laid back.
  • Early-Bird Cameo: Appears briefly in the last episode of Buddyfight X All Stars, battling his father shortly before Gao gets on his plane to America.
  • Headphones Equal Isolation: Averted Trope If Yuga's got his headphones on, it shows how serious he is.
  • Heroes Prefer Swords: While his father zigzagged the trope, Yuga plays it straight by using a sword as his go-to Item card during fights. However he averts this when using non-Dragon World decks where none of his items are swords.
  • Instant Awesome: Just Add Dragons!: His deck includes several monsters that are a part dragon (Garcat, Garbird, Gardog, etc.).
  • Last Episode, New Character: Made his first appearance at the end of Buddyfight X All Stars. It was revealed to be All Just a Dream, however.
  • Ninja: The main theme of his Katana World deck.
  • Red Oni, Blue Oni: The laidback Red to his buddy's stoic Blue.
  • Strong Family Resemblance: Like his dad he has two-toned hair and like his mom he has an Ahoge.
  • We Used to Be Friends: Defied. Despite Ranma's Face–Heel Turn and the latter saying they are done being friends, Yuga continues to see the former as his best friend and is happy that he got abuddy and became stronger. This attitude puzzles Eden and infuriates Ranma.

Subaru Hoshiyomi

Star Dragon World

Voiced by: Daiki Kobayashi (JP), Oscar Derkx (EN)

A student of Aibo Academy known as the Ace of Study for his knowledge and intelligence. He is seen as difficult to approach, as though there was an invisible wall between him and other people. His buddy is Skyseer Dragon, Cross Astrologia.

Subaru plays a Star Dragon World deck focused on the Astrodragon attribute with the goal of completing the Galaxy Formation which requires having an item equipped as well as monsters in the center and left. Doing so unlocks the abilities of his monsters and items and allows him to cast his Impact card.


  • The Ace: Subaru is known as the Ace of Study, a genius prodigy.
  • Archer Archetype: Reserved, skilled and both his item and impact cards are bows.
  • Child Prodigy: A middle schooler with a advanced knowledge of math, science, and literature.
  • Fake Defector: When he lost to Vile Ranma, he was given a lostrize card to transform Cross and berated him for not withstanding Vanity Husk's attack and it looked like he was interested in joining up with Ranma. All of this was a ploy to get close to Ranma and expose Vanity Husk to the Buddy Police. Not only that, he also attempts to get Ranma back.
  • The Stoic: He doesn't show a lot of emotions. However...
    • Not So Stoic: In episode 5, he's shown to be genuinely laughing at one of Yuga's videos. Specifically, at the fact that Garga uses tiny sword-shaped toothpicks to eat octopus dumplings. Cross quickly notes how odd his sense of humor is...
  • Some Kind Of Forcefield: Played for Laughs, Subaru seemingly generates one through his sheer indifference.
  • The Straight and Arrow Path: Despite playing the futuristic Star Dragon World, Subaru's item card is a bow. Justified, in that it may be a reference to Belomancy, a form of divination that used arrows which fits in with the overall theme of the Astrodragons.
  • Worthy Opponent: Quickly comes to see Yuga as one.

Masato Rikuo

Ancient World

Voiced by: Shūta Morishima (JP), Sam Duke (EN)

A transfer student known as the Ace of Sports. His buddy is Thunderaxe, Agito

Masato uses an Ancient World deck centered around the Linkdragon Order attribute and their ability to share certain skills between them through their Dragon Share ability.


  • The Ace: Like the other two main characters. Specifically, he is the Ace of Sports.
  • An Axe to Grind: To match his buddy's name, Masato's item card is a short axe on a chain. He also uses wooden axes during a training session with Mamoru.
  • Defeat Means Friendship: Inverted Trope, Yuga losing in a game (by trying to match Masato move instead of taking an easy win) is what causes the two to become friends. Played straight in regard to Banjoe Onizuka.
  • Expy: Like Genma before him, Masato's an Ancient World user with his own personal crew that sings their own theme song.
  • Lovable Jock: So nice and friendly, that he quickly befriends his entire class. Also, when all of Aibo's sports clubs beg him for help, he offers to aid them all.
  • The Power of Friendship: Masato is a firm believer in this and his deck reflects this with the Linkdragon Order's ability to share effects with one another.
  • Spirited Competitor: Challenge him at a sport and he'll gladly accept.
  • Secret Secret-Keeper: Becomes one for Mamoru whom he saw transform into Cosmoman while training. This becomes a moot point as Mamoru reveals it later in the same episode.
  • Team Spirit: The Linkdragon Order, to the point of having their own team cheers when they are ahead!
  • New Transfer Student: Transfered to Aibo Academy in the fourth episode.
  • We Used to Be Friends: With Daijiro until their differing viewpoints led them apart.

     Supporting Characters 

Haru Mikado

Voiced By: Rimi Nishimoto (JP), Calen Belden (EN)

Voiced by: Yuka Ozaki (JP), Caitlynne Medrek (EN)

Paruko's niece as well as Yuga and Haru's maternal cousin. She follows in her aunt's footsteps as a commentator for Buddyfights. Her Buddy is Takokichi, a Hero World monster.


  • Combat Commentator: Fulfills this role for Ace but unlike Paruko, she shares this role with her buddy.
  • Generation Xerox: Of her aunt, Paruko Nanana, in terms of role and world of choice. Even their respective buddies are similar.

Banjoe Onizuka

Danger World

Voiced by: Kentaro Tone (JP), Reamonn Joshee (EN)

A young delinquent and student from Aibo Academy as well as one of the participants in the ABC Cup Tournament. His buddy is Topfist Vainglory, Brawlzeus.

He plays a Danger World deck focusing on the Godpunk attribute and their playstyle of plundering the opponent's ressources through the effects and costs of his cards.


Miko Mikono

Katana World

Voiced by: Ayasa Itō (JP), Lauren Woods (EN)

A girl whose family owns a restaurant. She is a fan of the Ran-Ga channel. Goes to a different school from Aibo. It's later revealed that she and Yuga were friends back in preschool and would play together after school. Her buddy is Amaterasu.

Miko is a Katana world player whose deck is based around the Electrodeity attribute. Her playstyle involves placing Size 3 monsters on top of her item at the start of each turn, giving her their power and abilities which is represented in the anime by said monsters temporarily possessing her.


  • Childhood Friend: Yuga's.
    • Forgotten Childhood Friend: Yuga had initially forgotten her and it took some time for him to remember her. Admittedly justified in that they were both very young at the time.
  • Miko: Fitting her name, her attire seems to somewhat resemble the attire of one. This ties into the japanese mythology theme of her deck and its strategy of acting as a medium for her monsters.
  • Repetitive Name: Miko Mikono.
  • Supreme Chef: Her pizza is delicious.
  • Willing Channeler: She can let herself be possessed by her buddy or other monsters in order to gain their powers.

Mel Yumegatari

Dungeon World

Voiced by: Saori Hayami (JP), Lexi Ly (EN)

A shy girl who attends Aibo Academy and likes fairy tales. She has a crush on Subaru but has trouble approaching him. Her buddy is Red Riding Hood Emma.

She plays a Dungeon World deck focusing on the Folktale attribute, focusing on storing her destroyed monsters in the soul of her item so as to later call them back to the field to re-use their effects and unleash another wave of attacks on her opponent or to defend herself.


Mamoru Sekai

Hero World

Voiced by: Natsuki Hanae (JP), Lucas Seeger (EN)

A student from Aibo Academy who, with the help of his buddy, moonlights as a superhero fighting monsters. His buddy is Galaxy Exalt, Cosmoman.

He plays a Hero World deck based on the Galaxy Exalt and Galaxy Defense Team. His strategy is to transform into his buddy and unleash devastating high-critical attacks. However, he can only stay transformed for a limited amount of time depending on the amount of cards in his soul and if he has no soul left by the end of the turn, the transformation will end. However, this will give him the chance to use his impact card to try and end the game.


  • Anime Hair: His would be otherwise fine if not for the strand of yellow hair looping around his head.
  • Desperation Attack: His impact card can be seen as this, as it can only be cast when Mamoru's transformation into a Galaxy Exalt monster is about to end.
  • Henshin Hero: Both in and out of Buddyfights.
  • Secret Identity: Mamoru initially kept the fact he was fighting dangerous monsters as Cosmoman a secret with Masato only learning about it accidently. He eventually decides to reveal it during is buddyfight with the latter.

Light Kurouzu

Darkness Dragon World

Voiced by: Shouta Aoi (JP), Adam Forward (EN)

The son of Gaito Kurouzu from the previous series. He is a student at Aibo Academy and was a participant in the ABC Cup. He's also a member of the Buddy Police. He uses Darkness Dragon World but has yet to be featured in an onscreen fight. His buddy is Black Dragon Knight, Geil, although on a temporary basis.

His deck is based around the Curse Dragon attribute and revolves around using effects to place cards under his opponent's flag which, in conjunction with a Set spell card can allow him to immediatly win the game.


  • Berserk Button: Light does not appreciate when people start bringing up destiny around him or start comparing him to his father.
  • Composite Character: As noted below, Light is similar in some aspect to his father Gaito but his role as a kid who works for the Buddy Police is reminiscent of Tasuku.
  • Eyes Always Shut: Light's eyes are always closed. Until episode 26.
  • Foil: To Yuga. Both are the sons of main characters from the previous series but while Yuga managed to avoid being stuck in Gao's shadow by doing his own thing and starting buddyfight recently, Light had knowledge about how to play the game taught to him by Gaito but has difficulty avoiding being compared to him, leading him to act rebellious toward him.
  • Generation Xerox: Like his father before him, Light is the resident Darkness Dragon World player, their buddies are similar, if not the same and they even have similar playstyles which include an instant win condition, the latter of which was lampshaded in-universe. Otherwise averted in that thus far he's been shown to pretty much be the opposite of his father in every way, being more approachable and hating the word destiny.
  • Mr. Exposition: Is the one to tell Masato about Mamoru's past. Justified in that Mamoru was his opponent for the first round of the tournament and he gathered info about him.
  • The Infiltration: To find out what is going on with Vile Ranma's group, Light goes undercover infiltrating their group.
  • Screw Destiny: Unlike his father, he doesn't believe in fate. Averted at the end of episode 33 where he claims it's his destiny to defeat Destroyer, though this is to prevent forcing Yuga to do so as he knows he won't do it.
  • Spell My Name with an "S": Is it supposed to be Light or Raito? The official subtitles went with the former.

Kanesada Kaji

Katana World

Voiced by: Seiji Maeda (JP), Daniel Fong (EN)

A young man who acts like a samurai and participates in the Ace Buddyfighter Play-offs. He is the first opponent Yuga faces in the shop preliminaries and the one who gave him the idea of playing Katana World. His buddy is Steelframe Swordsman, KUROGANE.

He plays a Katana World deck centered around the Bladedancer monsters and Excelblade items. His playstyle revolves around not attacking with the item he equipped in order to be able to use his monsters' effects as well as his impact to destroy his opponent's cards and deal damage to them.


  • The Blacksmith: Kanesada was shown to have forged the sword he uses as an item card.
  • Foil: Can be seen as one to Zanya Kisaragi from the previous series, being Katana World users with a mechanical buddy monster and whose playstyle involve the use of Impact cards to counter his opponent's moves. The difference being that Zanya was usually serious and played a Ninja deck while Kanesada tends to be more comedic and associates Katana World primarily with Samurai, as seen with his confused reaction when Yuga played Ninja monsters.
  • Iaijutsu Practitioner: Whenever he uses his impact card.

Note Hibikase

Magic World

Voiced by: Natsumi Fujiwara (JP), Conrad Dickinson (EN)

A young boy who is the guitarist and leader of a band comprised of him, his buddy and two of his monsters. His lack of musical skill makes them unpopular.

Note plays a Magic World focusing on the Mystic Knight attribute. His goal is to cast spells belonging to the Fire attribute to power-up his entire field through the effect of his buddy, unlocking new abilities for his cards once they have reached a specific threshold.


  • Dreadful Musician: Note self-admitted that he has no knowledge in regards to playing the guitar.
  • Giftedly Bad: Note genuinely has no idea why his band is unpopular.
  • The Leader: Of the Scarlet Rose band he and his buddy are part of.
  • Meaningful Name: His anme is Note, fitting for a musician.

Eden Hanazono

Legend World

Voiced by: Marina Inoue (JP), Anna Cummer (EN)

The Student Council President of Saint Order Academy and one of the participants in the final round of the Ace Buddyfighter Play-offs. Her buddy is Archangel Dragon, Gavriel.

Eden plays a Legend World deck focused around the Empyreal Corps attribute and their Advent ability which lets them be called during the opponent's attack phase, giving her additional defense while she uses cards to punish the opponent for dealing damage to her life.


  • Cool Mask: Wears a mask that obscures the upper half of her face. It's shown that the staff and the other students of Saint Order are also made to wear one. She eventually throws it away after abandonning her Knight Templar mindset.
  • Deliberate Injury Gambit: Her deck's s playstyle in a nutshell. She lets her opponent damage her life so that she can use her buddy's Judgment ability and her impact card, letting her take away a good chunk of their life.
  • Disproportionate Retribution: Dishes Electric Torture to Dan to punish him for defacing a statue at her school when he refuses to apologize.
  • From Nobody to Nightmare: She went from being an ordinary student to the Academy's de facto ruler who imposes her philosophy on both the student and the staff.
  • Knight Templar: Eden's desire to bring order is genuine but she goes overboard in accomplishing her goal. She grows out of this thanks to Yuga.
  • Meaningful Name: Her last name translates to Flower Garden which, alongside her first name, is an obvious reference to the Garden of Eden. Fittingly, she uses a deck comprised of angels.
  • Student Council President: Of Saint Order Academy.

Rei Urameshi

Darkness Dragon World

Voiced by: Wataru Hatano (JP)

One of the eight participants in the final round of the Ace Buddyfighter Play-offs. Little is currently known about it, outside of how little information can be found about him and that he plays Darkness Dragon World.

He plays a Darkness Dragon World focused on Darkvenom Dragon monsters such as his buddy Deathraider, Orven. His goal is to amass multiple copies of the spell Venom Swamp and use their effects to quickly deplete his opponent's deck.


  • The Ghost: He has made no appearance on-screen and the one image of his face had been obscured. He is even this in-universe as all the characters know about him is that he plays Darkness Dragon World. Eventually subverted as his appearance is fully unveiled during his fight against Ranma.
  • Insane Troll Logic: He constantly pulls pranks on people so that they'll be miserable and he'll eventually have all the happiness in the world. That's his entire motivation. It's so absurd that only Subaru takes the fact that he believes it at face value while everyone else thinks he's the exact opposite.
  • Poke the Poodle: Part of the whole reason no one but Subaru takes his beliefs seriously. His pranks tend to either be inoffensive or achieve the exact opposite effect.

     Antagonists 

Dan "Da Dan" Yamada

Dragon World

Voiced by: Hiroaki Miura (JP), Logan Shave (EN)

A PalTuber who makes videos of himself causing mischief and playing pranks on others. He harbor a dislike for fellow PalTuber Yuga and several of his schemes are meant to humilliate him or drag down his reputation. He later becomes an ally of Vile Ranma in order to defeat Yuga.

He plays a Dragon World deck centered around the Dragonblood Sect attribute and spearheaded by his buddy Bloody Eyes who later evolves into Deadly Eyes. The latter's ability, allows him to negate the abilities of other monsters and force them to attack him, only for them to then get destroyed by his own Counterattack ability and trigger the effects of Dan's cards.


  • Butt-Monkey: Nothing goes right for this guy. Even Ranma and his group, whom he has allied himself with, don't give him much in terms of respect.
  • Curb-Stomp Battle: On the receiving end of one from Miko, of all people. He doesn't get the chance to so much as deal a single damage to her. He doesn't fare much better against Eden.
  • Do Not Call Me "Paul": Dislikes being called by his full name due to finding it too plain, prefering to go by "Da Dan" instead.
  • Eaten Alive: Destroyer devours him as retribution for his failed attempt at rebellion.
  • Evil Counterpart: To Yuga. Both are PalTuber who play a Dragon World deck but while Yuga uses his channel to entertain others, Dan only makes videos of him playing pranks and causing mischiefs for others.
  • Eyepatch of Power: Dan wears an eyepatch despite both of his eyes being functional, possibly in an attempt to look cooler in the eyes of others. However, he lacks the "Power" part of the trope due to his role as the resident Goldfish Poop Gang.
  • Fashionable Asymmetry: Dan seems to be invoking this trope by wearing an otherwise unnecessary eyepatch. Then there's his item card which manifests as a single glove.
  • Goldfish Poop Gang: Da Dan is a recurring antagonist, out to cause trouble for Yuga and his friends but none of his schemes haves succeeded, be it due to outside interruption or his own fault.
  • Jobber: His role in the series is this, having lost all of his fights thus far. Even his buddy evolving didn't help him.
  • Nonstandard Character Design: His facial features are more angular that those of other characters and his mouth has nothing but his teeth visible.
  • Paper-Thin Disguise: One of his schemes had him try and frame Yuga for his actions by wearing a badly-made mask of Yuga's face.
  • Villainous Crush: Appears to have a crush on Miko and attempts to make her into his channel's idol.

Ranma Kakogawa

Dragon World/Lost World

Voiced By: Kei Shindo (JP), Conner Christmas (EN)

Yuga's best friend, co-producer of their Ran-Ga youtube channel, and the one who introduced him to Buddyfighting. Having played for the past three years, Ranma possesses the experience and knowledge that Yuga lacks.

Lacking a buddy monster of his own, Ranma uses a deck based around the Crimson Battler archetype of Dragon World. This gets overridden with a hybrid Dragon World deck that eventually becomes a Lost World deck by using the Lost World Flag, which has the ability to change the deck to a Lost World Deck with Vile Demonic Dragon, Vanity Husk Destroyer as his Buddy.


  • Big Bad Slippage: As previously mentioned he was the main characters best friend. Got him into buddyfight and even gave him cards to bolster his deck. Then he starts to get resentful after Yuga started making more friends. Had some visible irritation when Yuga beat him in the tournament and finally began rooting for his opponent during Yuga's battle with Subaru. After Yuga's tournament victory he shows up, challenges Yuga and then undergoes a Face–Heel Turn, an Evil Makeover, and starts showing off Manipulative Bastard tendencies cementing himself as the Big Bad.
  • Contrasting Sequel Antagonist: Twofold.
    • To all of the Major Antagonists of the original generation. Whereas Kyoya, Ikazuchi, and Wisdom were already enacting their plans and Gao had no prior relation to any of them before setting off to stop them, Ranma and Yuga are ex best friends, with Ranma's turn to evil being directly related to Yuga. And whereas the other villains had plans on grand scalesnote , Ranma's only goal so far has been hurting Yuga and his friends specifically. Finally, wheras the previous three's relationships with their Buddies ranged from convenient till it serves their need (Kyoya) to abusive on one side or the other (Ikazuchi being used by Yamigedo, Wisdom's Fantastic Racism, though both in the end got better), Ranma and Destroyer are friendly and glad they're Buddies from the start.
    • To Kiri/Miserea. Whereas Kiri's cause for Face–Heel Turn was amplified by the effects of the Dark Core Deck Case given to him by Davide, Ranma's reasons existed before even meeting Vanity Husk Destroyer, to his own horror no less. And while Kiri's issues were caused by reasons beyond his controlnote , Ranma's issues were directly a result of his own decisions.note 
  • The Corrupter: Ends up being on both sides of this trope with Vanity encouraging him to turn against Yuga and Ranma himself being this trope for Seiji with the aim of ultimately corrupting Subaru.
  • Dude, Where's My Respect?: Despite having played for the last three years, people forget how experienced he really is and tend to underestimate his skills, much to his frustration during the ABC Cup.
  • Expy: Of Kiri, being a friend of the protagonist who started without a Buddy and, due to feelings of inferiority and resentment toward the main protagonist, ends up making a Face–Heel Turn which coincides.
  • Evil Makeover: After he reveals the Lost World Deck his hair becomes spiker and he gains a new clothing. It's shown that he can return to his previous look if he wishes to.
  • Face–Heel Turn: After becoming Vile Demonic Dragon, Vanity Husk Destroyer's buddy.
  • Heroic BSoD: Seems to be slowly heading for one due to lacking a Buddy of his own...
  • Good Old Fisticuffs: As said, he uses Crimson Battlers, who are all about hand to hand combat.
  • Lost in Translation: When Ranma first performs his Face–Heel Turn, Destroyer decides he needs a new name and points to the fact his card has the kanji for "Rebellion Demon", read as Ranma. His original name had no meaning as it was written in Katakana, so he changed the writting to Kanji to reflect the Face–Heel Turn. As the meaning is lost outside of Japanese, he instead takes on the moniker of Vile Ranma in English.
  • O.O.C. Is Serious Business: Ranma is usually supportive of Yuga, so when during the latter's rematch with Subaru, he starts screaming for Subaru to crush Yuga, something is not right.
    • During Yuga's victory party as Yuga has been 'calling Ranma for Hours' Ranma suddenly spontaneously shows up. He's almost emotionless, asking if the party is somewhat big, takes the trophy and drops it while apologizing though immediately afterwards commenting on how the trophy is flimsy, and finally tells Yuga he doesn't have time to waste at his party and walks out the door! Haru begins crying right before Ranma leaves.
  • Manipulative Bastard: He was able to influence Seiji into turning against Subaru by exploiting the former's resentment towards the latter and being Not So Different from Ranma himself.
  • Out-Gambitted: His plan to get Subaru to join him end up backfiring as the former uses it to his advantage in order to get information on Ranma and his allies. Even his attempt at preventing Subaru from leaving is turned against him since Subaru had planned ahead and had the Gar trio nearby recording the whole thing and threaten to have the footage released, which would lead Ranma to lose his buddy and status as buddyfighter, if the latter doesn't let them go.
  • Stepford Smiler: Ranma tends to take things in stride and even when he's upset or jealous he's keen not to show it and tends to act friendly regardless of his own feelings. After his Face–Heel Turn he starts becoming much more openly antagonistic and vents his frustrations openly towards Yuga. Even using words he used in past episodes against him
  • Recurring Element: Fills the role of main antagonist of the show who uses a special flag.
  • The Resenter: In episode 2, Ranma appears to resent towards Yuga for having a buddy while he himself does not. Although he reassures Yuga that they're still friends, Ranma's resentment towards his friend continues to grow throughout the episodes.
  • Weak, but Skilled: Has a considerable depth of knowledge about the game, but lacks a buddy to bolster him up.
  • We Used to Be Friends: Tellingly what causes a lot of drama is that Ranma used to be Yuga's best friend. It goes without saying that Yuga's friends would like nothing more than to get them back together and Suburu challenges Ranma for exactly this purpose....and loses.

Seiji Kido

Star Dragon World

Voiced by: Yuki Yonai (JP), Ethan Snowden (EN)

A young chess genius. He met Subaru during a National Mock Examination and became friends with him. However, behind this friendship lies a resentment to Subaru due to being a second placer in the same examinations and losing to him in his first game of chess.

Initially not a buddyfighter even though he had a Star Dragon World deck of his own, this changes after he meets Vile Ranma and transforms his buddy Knight: Argento Lance into Lostknight: Nero Lance. His deck is centered around the Drametal attribute and makes use of the Oppress ability possessed by his monsters to gain control over his opponent's left and right zones.


  • Always Second Best: Feels like this toward Subaru. Not only has he become the second-best scorer in the Mock Examination but the former beat him in a game of chess even though he was a beginner who'd just been taught how to play. This is what drives him to accept Ranma's offer.
  • Borrowed Catchphrase: Borrows Daijirou's "win-win" expression to rub the former's defeat to Masato in his face.
  • Face–Heel Turn: In the very same episode he was introduced in no less.
  • Not So Different: Seiji is to Subaru what Ranma was to Yuga. This is even acknowledged in-universe by Ranma himself who uses this to corrupt him.
  • The Resenter: Resents Subaru for beating him in a chess tournament despite being less experienced, though he also hoped to befriend Subaru at the time.
  • Smart People Play Chess: He is a chess player who is second only to Subaru, the Ace of Studies, in terms of intellect.
  • The Starscream: After he finds out that he was just Ranma's pawn, Seiji plans to usurp the latter. However, this ends up being cut short after he sees first hand what happens to those who try and fail to do just that when Da Dan, whom Seiji had manipulated in challenging Ranma as a test, ends up devoured by Destroyer as a punishment.
  • Unwitting Pawn: The end of his debut episode reveals that he is not the person Ranma wanted to have an ally, only a stepping stone so that Ranma can get to Subaru, his real target. That being said, he still is one of Ranma's allies, even helping him set up the Vile Ranma channel. He is far from happy with Ranma when he learns the truth.

Daijiro Kurayashiki

Ancient World

Voiced by: Daichi Endō (JP), Phil Fulton (EN)

The young heir to the rich Kurayashiki family. In exchange for having his buddy powered up with a Lostrizer card, he provides Vile Ranma with money. He was formerly a friend of Masato but differences in terms of how they regard other led them to go their separate ways.

Daijiro plays an Ancient World deck focused on the MAX Dragon attribute and continuously evolving his buddy Domilord, Zerberos into stronger forms while his Overcrest spell lets him bypass the size limit, allowing for these forms to be played in the first place. He previouly had the Linkdragon Order who follow Masato in his deck but threw them away after losing.


  • But Now I Must Go: Daijiro said that if he did not win his fight during the Ace Buddyfighter finals against Masato, he would not return to Vile Ranma's lair. He loses and of course does not return to Vile Ranma's confusion and frustration.
  • Catchphrase: Daijiro often refers to a mutually advantageous situation as being "win-win".
  • Evil Redhead: Daijirou is an antagonist and his hair is two different shades of red.
  • Evil Counterpart: A clear-cut example toward Masato. Both are talented in sports and use Ancient World decks but unlike his former friend who believes in teamwork, Daijiro has no patience for those he regards as weaklings and will abandon them the moment he sees they're worthless, as he did with the rugby team and the Linkdragon Order monsters. This is even reflected in their respective playstyles with Masato's Linkdragon Order cards being all about sharing their poweres with each other while Daijiro's deck revolves around keeping only one monster on the field and making it even stronger by continuously evolving it.
  • We Used to Be Friends: He and Masato were once friends but they had a failling out after Masato refused to abandon a rugby team the two of them had joined after a loss.

Buddies and other Monsters

    Buddy Monsters 

Gargantua Dragon

Voiced By: Tetsu Inada (JP), Steve Olson (EN)

Yuga's Buddy Monster and the owner of the Gargantua Punisher. Wishing to become stronger, Gargantua Dragon decides to come to Earth a partner with a human, namely Yuga. Yuga, finding Gargantua's name hard to say, decides to nickname him Garga, which he finds acceptable.

In Buddyfights, Garga's main usage is his G.Evo ability, allowing him to change into a different form with different abilities after he's finished attacking.


  • Armored Dragon: Gargantua is one. However, he doesn’t have the Armordragon attribute.
  • Badass Baritone: Which he retains in his SD form.
  • Big Eater: Likes the same foods as Gao's Buddies and eats even more than they do.
  • But Now I Must Go: Subverted. He assumed that the conflict between himself and Vanity Husk Destroyer would lead him to leave Yuga behind. Turns out not to be the case in the end, especially when considering Destroyer's Heel–Face Turn after the Ace Buddyfighter finals.
  • Composite Character: In terms of cards, he is similar to Drum and Batzz due to having Soulguard like the former and, like the latter, the ability to attack multiple times thanks to both possessing the Double Attack and through its own effect. However, Gargantua’s “G•EVO” gimmick has more in common with Bal and Jackknife since it operates by calling a new form from on top of itself. In terms of backstory, he has aspects of Batzz due to being an ancient being with his own group of supporters, Bal due to being a deity, and Drum for coming to Earth to become stronger.

Vile Demonic Dragon, Vanity Husk Destroyer

Voiced by: Hiroki Yasumoto (JP), Fraser Tuff (EN)

A Lost World monster and Ranma's Buddy. He and the rest of his world were sealed away in another dimension by Gargantua Dragon when the worlds were young.


  • Affably Evil: For a demonic dragon hailling from a world of destructive monsters, Vanity is rather affable and seem to get along well with Ranma.
  • Attack of the 50-Foot Whatever: Vanity Husk and Vanity Ep are already big, but Vanity End Destroyer is so huge, it uses it's previous two forms as hands as though the previous two forms were just fighting his fists.
  • Because You Were Nice to Me: After losing to Yuga and Garga in the Ace Buddyfighter finals, Destroyer decides to drop his revenge and his ambition in favor of Ranma who treated him with nothing but respect. He decides to pay his sentence, and under Ranma's suggestion, decides to be his buddy again.
  • Body Horror: That's exposed muscle under his armor.
  • The Corrupter: To Ranma, whom he encourages to resent Yuga for his easier life and cut off all ties with him with him as a path to strength.
    • He's also this in another way as he can infect other monsters with his cells through Lostrizer cards which transforms them into stronger forms.
  • Emotion Eater: Destroyer absorbs Minus Power, which is born from an individual's repressed and negative feelings. After he absorbs enough of it, he evolves and gain a new form.

  • Frickin' Laser Beams: He attacks with two laser cannons each attached to the armor on his shoulders and wrists.
  • Implacable Man: Vanity End Destroyer takes it Up to Eleven. It puts the fighter's entire hand and deck into it's soul, makes the fighter unable to lose as long as it's on the field which can't be nullifed nor can the soul cards be discarded by effects, and allows the fighter to pick any card from it's soul to put into their hand. The only other Big Bad to match this was Evil Deity of Cataclysm, Hyakugan Yamigedo, who required two halves to summon and a 100 card deck to effectively use it's own special soulguard.
  • Intangible Man: He doesn't have a mini form at first, so he phases through walls to get into tight spaces.
  • Our Dragons Are Different: A demonic dragon with a cannon on its back and with a skull-looking shell he can cover itself with. Also, his cells can be used to transform other monsters.
  • The Pirates Who Don't Do Anything: In spite of his in-universe reputation as an evil and dangerous monster, Destroyer seems content with following Ranma's lead. Until he eats Da Dan as retribution for the latter's attempted rebellion. Then it's revealed that he's biding his time until Ranma can power him up enough with his Minus Power.
  • Revenge: Destroyer's goal is to take revenge on the deities who sealed him and Lost World away.
  • Sleep-Mode Size: As Vanity End Destroyer, he finally gets one in the form of a disembodied, skull-like face.

Lostknight: Nero Lance

Voiced by: Yu Okano (JP), Neil Minor (EN)

A Star Dragon World monster and the buddy of Seiji Kido. He was originally Knight: Argento Lance but was transformed into its current form through the use of a Lostrizer card. Later, he evolves into Lostknight: Nero Schiltlance after being powered-up by a second Lostrizer card.

As a Drametal monster, he has the ability called Oppress which lets him move to his opponent's left or right zone, provided it is empty and have it be treated as a zone controlled by his player. Additionally, he can inflict 2 damage to the opponent when his controller's turn ends if he is on such a zone.


  • Ambiguous Situation: It's unclear whether Argento Lance was an actual contracted Buddy, or simply the card Seiji used as his buddy. If the latter, then Nero Lance was technically given life from the Lostrizer card. If the former, then Argento Lance was afflicted with The Corruption by Seiji unwillingly.
  • Blade Below the Shoulder: His left arm ends in a lance.
  • Discard and Draw: After becoming Nero Schiltlance, he exchanges his ability to deal damage at the end of the turn and soulguard for the ability to remain on the field after being destroyed at the cost of 1 gauge.
  • Evil Makeover: The Lostrizer card inverts his color scheme from white and blue to black and red.
  • Our Centaurs Are Different: A metallic dragon centaur.
  • Our Dragons Are Different: Nero Lance is an eyeless dragonic centaur with a metallic look.

Bloody Eyes

Voiced by: Yoshikazu Sakai (JP), Tyrell Crews (EN)

A Dragon World monster and the buddy of Dan "Da Dan" Yamada. After being powered-up by a Lostrizer card, he becomes known as Deadly Eyes.

He has the ability to take control of other monsters' minds and force them to attack him only to get destroyed by his Counterattack ability and trigger its other effect to deal damage to the opponent.


  • Chuunibyou: Of the "Evil Eye" type.
  • The Corruption: Ranma transforms him into Deadly Eyes with a Lostrizer card.
  • Do Not Call Me "Paul": Dislikes having the first part of his name being said outloud due to it being his so-called soul name. This remains true even after his transformation.
  • Goth: The inspiration for his outfit.
  • Draconic Humanoid: A human-like dragon to the point of him having hair and wearing clothes.
  • Magical Eye: The source of his mind control ability. We haven't seen if that is the case.
  • Red Eyes, Take Warning: As Deadly Eyes, his previously-obscured left eye is revealed to be a glowing red eye.

Domilord, Zerberos

An Ancient World monster and the buddy of Daijiro Kurayashiki. Like Nero Lance, he was powered up by a Lostrizer card but un like the latter, instead of changing its base form, it gave him an additional form. He later gains another new one by being powered-up by a second Lostrizer card.

Domilord possesses stronger forms he can evolve into, all of which are 1 Size higher than the previous one and ending with the powerful Size 6 monster Emplord, Zerberos Lost. Said forms all have the "Against All Odds" ability which prevents them and all cards their player controls from being destroyed, returned to the hand or put into rest position by effects so long as they are the only monster their player controls.


  • Composite Character: Being an Ancient World monster with an evolution gimmick brings Duel Sieger back to mind while his stronger forms being Size 4 and greater and needing a spell on the field to bypass the Size Limit on top of being the buddy of an antagonist from a rich family is reminiscent of Azi Dahaka.
  • The Corruption: As evidenced by the name, Zerberos Lost is a form that was acquired thanks to being powered-up by a Lostrizer card.
  • Discard and Draw: Almighty Overlord, Zerberos loses his ability to destroy all of the opponent's card and deal 1 damage for each in exchange for increased power, defense and critical.
  • Evolutionary Levels: Like Duel Sieger before him, Zerberos has several evolutions, each stronger than the prvious one, which need to be played in a specific order. However, unlike the former, said evolutions are of increasing size, instead of being all size 3.
    • Domilord, Zerberos (Size 3) —> Tyralord, Zerberos Aog (Size 4) —> Viclord, Zerberos Zeed (Size 5) -> Emplord, Zerberos Lost and Almigty Overlord, Zerberos Lost (Size 6)
  • Mighty Glacier: All of Zerberos's forms boast have high stats and the ability to at least attack twice and theit "Against All Odds" ability make them hard to get rid of since it protect not only themselves but all cards their player controls, including the Overcrest card that is necessary to get the stronger forms out on the field in the first place.
