Characters in Yu-Gi-Oh! SEVENS.
Goha Seventh Elementary (ゴーハ７小, Gōha Nana Shō)
Ranze and Rinnosuke (蘭世, Ranze & 凛之介, Rinnosuke)
Voiced by: Yuna Kamakura (Ranze), Chiaki Kobayashi (Rinnosuke)
Twins Ranze and Rinnosuke are respectively the Vice President and Secretary of the school, assisting Gakuto in enforcing the rules.
The twins play Flowerfang Decks, a Plant deck based on ninja. Ranze's deck focus on swarm tactics while Rinnosuke's use destruction effects and burn damage.
- Amazon Brigade: Ranze's Flowerflang monsters are kunoichi.
- Annoying Younger Sibling: Played straight, then inverted. Rinnosuke occassionaly becomes one when teasing Ranze, but their roles are reversed when Ranzes Crush Filter antics get out of hand and he has to snap her out of it.
- Ascended Extra: Originally just Gakuto's assistants, Goha 6th upgrades them, especially Ranze, to part of main cast for the arc.
- Deconstructed with Ranze. After receiving additional focus during the Goha 6th Arc, she starts to imagine herself in scenarios where she is the main protagonist, eventually deciding to leave Gakutos service so she could strike out on her own.
- Beleaguered Assistant: Not to Gakuto, who is as hardworking as them, but towards Romin when the three of them try to help her disastrous cooking attempts, resorting to swapping in the items she needs. Later played straight with Rinnosuke towards Gakuto when he tries to evolve the Sogetsu style into modernity.
- Cloudcuckoolander: Ranze is eventually revealed to be this. Her "Ranze Eyes" delusions heavily skew her perception of reality.
- Deadpan Snarker: Ranze is shown to be rather snarky, and was much more critical of Romin's terrible attempts to cook.
- Divergent Character Evolution: They start off basically the same except for gender, but in the Goha 6th Arc, they begin to diverge with their cynicism and idealism, overall loyalty, personalities, and playstyle. In the Team Battle Royal arc, Ranze even leaves Gakuto's service while Rinnosuke remains behind.
- Dub Name Change: To Rayne and Rino in the English version of Yu-Gi-Oh! Rush Duel: Dawn of the Battle Royal.
- Expy: They are similar to Tsukikage and Hikage as both pairs are sibling Ninja duelists who use the same deck and even have one sibling, (Ranze and Tsukikage), gain more prominence over the other.
- Half-Identical Twins: Ranze and Rinnosuke are both bespectacled with similar features and hairstyles, the only difference being Rinnosuke having a slightly darker hair color.
- Honest Advisor: Despite their loyalty, they are willing to call out Gakuto when they believe he is shirking his duties for his interest in "Rush Duels", and Ranze even attempts to circumvent his orders in the Duel when he is hesitant about playing all out.
- I Choose to Stay: Inverted with Ranze. Even after coming back to her senses following her duel with Gakuto, she still chooses to leave his service, feeling as if she has no right to stand by his side anymore and began serving Neiru instead. She later returns to Gakutos side after he impresses her in his duel against Neiru.
- Lady of War: Ranze is an elegant duelist ninja, having the same sort of traditional Japanese music playing while she duels as Gakuto does.
- Legacy of Service: Their family has served the Sogetsu family as ninja for generations.
- Ninja: Aside from their Flower Fang deck, they serve as such to Gakuto, even doing the ninja run on the way to the Training Camp.
- Not So Above It All: Despite his serious nature, Rinnosuke isn't above acting like an Annoying Younger Sibling to tease Ranze for her crush on Yuga and is later shown to have a Crush Fliter like his sister, only he doesnt let it get out of hand.
- Only One Name: Their surnames are unknown, until episode 29, which is Nanahoshi based on the dueling style.
- Petal Power: Despite being Plant-types, Ranze's monsters appear humanoid, but attack with various flower-based attacks.
- Recurring Element: The Ninja duelists of the series - though unlike previous Ninja duelists, their decks are Plants instead of Warriors.
- Serial Romeo: Ranze apparently gets crushes really easily, to Rinnosuke's frustration.
- Single-Minded Twins: Subverted, while both of them have the same strict personality and Undying Loyalty towards Gakuto, they are later shown to be quite different: Ranze is sarcastic and more cynical towards Yuga and Co, despite her crush on Yuga and tends to be delusional about her love life, while Rinnosuke is more upbeat and down to earth, and even though he can be similar to his sister in his delusions, he is still more realistic.
- Stalker with a Crush: Ranze is this for Yuga, she even has a secret observational journal about him. It is later revealed she has a total of 73 Journals from other crushes she has observed!
- Stellar Name: Their surname, Nanahoshi means "seven stars".
- Stoic Spectacles: Both of them wear glasses to go with their level-headed personas.
- Taking You with Me: Rinnosuke ends his duel against his sister with a DRAW.
- The Thing That Would Not Leave: Ranze becomes this to Neiru, trying to become his personal agent, but he keeps trying to get her to go home instead.
- Thinks Like a Romance Novel: Ranze, when she gets a crush on both Yuuga and Galient, complete with a Crush Filter and Imaginary Love Triangle, with Rinnosuke trying to break her out of it before she humiliates herself.
- Too Important to Walk: Like Gakuto, both Ranze and Rinnosuke have someone else hold and Set their cards for them; Rinnosuke does it for Ranze during her duel against Galient, and Gakuto tricks Luke into doing it for Rinnosuke in his duel against Ranze.
- Undying Loyalty: The pair uphold Gakuto in high regard, and rarely question his authority as Student Council President. They also cheer for him during his duels, and swear that if Gakuto dies, they will die with him so he does not have to perish alone. Ranze starts to question this, her crush on Galient making her duel against Yuga and Co on his behalf and her dueling Gakuto to strike out on her own, and leaves to try to make Neiru her new master before eventually returning to Gakutos side.
The Newspaper Club (Bakuro Shinjitsu, Masaru, and Nico)
Voiced by: Tomoya Yamatao (Bakuro), Kentaro Kumagari (Masaru), Saki Yasui (Nico)
A trio of aspiring young journalists led by Bakuro Shinjitsu. The group is infamous among the student body for its sensationalist and heavily biased articles, but the fact that it distributes them through print makes their newspaper one of the few information outlets that cannot be directly controlled by the primarily digital Goha Corp.
Bakuro plays a Reporter Deck of machines based on printing materials.
- Berserk Button: The usually quiet and dour Bakuro freaks out and has a drastic shift in personality whenever the mere possibility of his newspaper being discontinued pops up.
- Camera Fiend: Nico, who constantly takes pictures of everyone as the paper's photographer, and usually adds that they're for something demeaning.
- Cute Machines: Delivery Machine Whirr, whose hologram panics when it is destroyed by Luke's Dragon. Toughroid significantly less so.
- Da Editor: Bakuro is the chief of the Newspaper Club, though oddly for this trope, hangs out in the background and lets his underlings do their own thing.
- Defeat Means Friendship: Upon being defeated by Luke, Bakuro comes to enjoy "Rush Dueling" and they write a proper article for "Rush Dueling", along with a ridiculous one of Luke being King at his request.
- The Dividual: Symbiotic version. They have varying traits but work in tandem as one, though with Bakuro the most prominent due to being the Duelist. His defeat serves as the reformation of the paper as a whole.
- The Face: Masaru serves as one for the Newspaper club as the reporter, therefore the protagonists are shocked when Bakuro is revealed to be the chief, as before he had been the note taker.
- Hypocritical Humor: Bakuro's primary reason for trying to discredit "Rush Duels" is that he sees them as so easy and simple to understand when he, someone who has a hard time remembering things, can pull off massive plays that would otherwise be difficult for him in regular Duels. This doesn't stop him from greatly enjoying himself when he puts Luke on the ropes.
- Immoral Journalist: Before the protagonists set them straight. Masaru and Nico still have shades of this with their questions for Tiger during her Duel with Zomyoji, and are yelled into the sky both times. Bakuro however has shown to instead be a noble Intrepid Reporter
- Intrepid Reporter: Bakuro after becoming much more kind, even standing up to Hunt due to the latter's greed and jerkassy.
- Mythology Gag: Bakuro's ace monster is News Flash Machine Toughroid, similar to Syrus's roids, and his deck's monsters are living machines like them.
- School Newspaper News Hound: Invoked by Yuga, since the print media is a good way to avoid Goha Corp's censoring. Luke is skeptical at first, but their paper is surprisingly influential among their classmates.
- Slapstick Knows No Gender: Nico being a girl doesn't prevent Tiger from yelling her into the sky with Masaru when their interviewing annoys her.
- Smug Snake: Bakuro, due to considering "Rush Duels" rather childlike, is condescending towards Luke during their Duel, even mocking how easy it is. He is however, still a difficult opponent for Luke, and proved capable of summoning three copies of his ace monster. Averted later, where he grows out of it.
- Took a Level in Badass: Later in the run, Bakuro acquires a Fusion ace, Lightning Speed, the Rumbling Report Warship, and uses it to take down Hunt and his Maximum Monster.
- Took a Level in Kindness: By the Goha Employee Arc, Bakuro has become a noble Intrepid Reporter that stands up to Hunt for his greedy, cruel acts.
- Trap Master: Bakuro plays a noticeable amount of Trap Cards that hamper and wreck the opponent.
Voiced by: Takuma Nagatsuka
Mimi's son and a fourth-grader of Goha Seventh who loves Good Max, a Henshin show based on Mad Max.
He plays a Beast Gear World deck, featuring post-apocalyptic Beast-Warriors.
- Ambiguously Absent Parent: He lives with his mother Mimi, but his father is nowhere to be seen.
- The Apunkalypse: Beast Gear World is based heavily on this, and Yoshio even watches a Mad Max-based show.
- The Baby of the Bunch: The youngest of the recurring characters, being two years under Yuga and Co.
- Badass Biker: All his monsters are dogs that ride motorbikes.
- Beast Man: His monsters are all Beast-Warriors.
- Cool Bike: Despite actually being a tricycle, it managed to be this, looking like an apunkalyptic bike with a ram skull on it, and is very helpful for getting the Newspaper Club to the Yuga-Roa duel to prove that Sevens Magician is a legal card.
- Dub Name Change: To Yosh Imimi in the English version of Yu-Gi—Oh! Rush Duel: Dawn of the Battle Royal.
- Field Power Effect: Beast Gear World, the first Field Spell used in SEVENS, which raises the attack of his monsters and lowers the attack of Dragon-Types.
- Locked Out of the Loop: At Mimi's request, Yuga and co. don't tell him that his mother is Number 6, and he is also unaware of his mother's spying.
- Mobile-Suit Human: He wears a cosplay suit of the protagonist of his favorite show that has this effect, making him seem like a burly muscle man... when he's actually Mimi's height.
- Momma's Boy: He greatly loves his mom - with his father not in sight - and his conflict with Luke is driven by a desire to "Rush Duel" without upsetting her.
- Took a Level in Badass: He returns in the Garden of Providence with a stronger deck and determination, even beating his mother.
- Trademark Favorite Food: Neapolitan pasta, to the point where the fear of not getting to eat it is what makes him challenge Luke.
Haruka "Tiger" Kamijo
Voiced by: Saeko Kamijo
Luke's older sister and president of the Concert Band Club. She plays a WIND Music deck of WIND warriors - Music Maidens - based around martial artists and woodwinds.
- Action Girl: She is a very skilled and competitive Duelist and the only named character who is capable of defeating Luke and even managed to defeat Yuga during their rematch.
- Always Someone Better: She's this to Luke, having defeated him in practically everything during their youth, even dueling, to the point that even after Luke's skills advanced dramatically once he could practice in adult Duel Centers, he still hasn't beaten her again (though it's left unsaid if he tried since getting his watch). He beats her as The☆Lukeman, but was losing before the possession.
- Amazon Brigade: The majority of her deck are Music Maidens aside from possibly her ace, which appears as a keyboard-like mecha despite being a Warrior-type.
- Anger Born of Worry: When Luke is missing in Episode 62, Tiger threatens to kill him if he doesn't come back, which Yuga lampshades.
- Anti-Magic: Her ace, Ensemble Fighter the Heavy Music Oni, prevents the activation of Trap Cards when it attacks. Her new Fusion, Full Orchestra the Phantasmagorchestra Music Oni, which uses the above monster as Fusion Material, lets her destroy all her opponent's Set Spell/Traps and power itself up for each one destroyed.
- Berserk Button: If you want to remain on the ground, don't call her by her normal name, call her Tiger. Asana is the only exception. Betrayal of family is another as she goes berserk when Luke betrays everyone.
- Big Good: Is this towards Goha Seventh Elementary.
- Big Sister Bully: She is a terrifying older sister, though she does care about Luke, happy that he enjoys himself when dueling.
- Blow You Away: Her deck consists of WIND monsters to go with her woodwind theme. Aside from the wind, she is associated with breath and she often blows people away when they press her Berserk Button - which is often.
- Cassandra Truth: She calls out on Yuga and Luke for attempting to help a zombified Swirly without explanation, though Yuga resists and faces off against her in a Rush Duel. There's a good reason Tiger is disrupting them; Swirly's true identity is that of Yuga Goha, the sixth of the Goha Siblings.
- Contralto of Danger: She's a tough-as-nails Action Girl with a deeper and husky voice.
- Childhood Friends: With Asana, bordering on if not a case of Pseudo-Romantic Friendship. A misunderstanding over Tiger thinking she was abandoned when looking for Luke on a snowy day - Asana and her great-grandfather had stumbled upon the half-frozen Kayama and Doverap and took them to the hospital- leads to her seeking vengeance. Though once it is cleared up they resume their friendship.
- Competition Freak: Incredibly competitive, though she is a Graceful Loser that takes her loss to Yuga well.
- Do Not Call Me "Paul": Insists she be called Tiger.
- The Dreaded: Luke is terrified of her, though not enough to actually call her by her insistent nickname. It gets to the point where she's the one Gakuto and Romin seek out to bring Luke's ego down a peg when needed.
- FaceHeel Turn: Stands in Yuga and Luke's way while they seek a cure for Guruguru during the Goha Employee arc, seemingly having sided with Nanaho. Subverted in that she was actually trying to prevent Yuga Goha's return.
- Glass Cannon: Although her deck is offensively powerful and able to summon many high-level monsters, her deck noticeably lacks much in the ways of protection or trap cards.
- Hair-Trigger Temper: Incredibly short-tempered, especially towards Luke, whom she considers an idiot, and everyone else that doesn't call her Tiger. Averted with Asana, and Yuga, even brushing off one of his roads accidentally electrocuting her.
- Hot-Blooded: To the point that Luke seems calm by comparison, if only because he spends most his time when she's present in a state of abject terror. Averted when she confronts Yuga and Luke during the Goha Employee arc.
- Martial Arts and Crafts: Haruka has a martial arts and woodwind theme. Justified in that she deliberately sought out the mastery of woodwinds in order to improve her breath abilities.
- Martial Arts Uniform: She also wears a red Chinese-styled gi.
- Musical Assassin: And Instrument of Murder, as her monsters attack with sound-based attacks and they carry weapons that merge woodwind instruments with martial arts weapons.
- Nice Job Breaking It, Hero: It turns out that The☆Lukeman is her fault, as her trying to fax The☆Lukeman manga and breaking it caused the program to gain sentience and create the Fusion cards, all for the purpose of becoming one with Luke.
- Ojou: A tyrannical Royal Brat type that rules the school with fear, albeit with her temper and strength rather than her wealth.
- OOC Is Serious Business: In the Goha Employee Arc, her not blowing up when Luke calls her Big Sis instead of Tiger alerts him to something being wrong.
- Poor Communication Kills: She doesn't bother to elaborate on why she opposes Yuga in the Goha Employee arc, and while it could be assumed that she figured Yuga wouldn't believe her about what was wrong with Guruguru, her opposition just made Yuga even more determined to help him and led to the return of Yuga Goha. Because of this, and due to hurting Yuga with said duel, Luke is left legitimately and seriously mad at her, and isn't willing to forgive her over it.
- The Rival: From childhood, one to Asana, though after their duel it switches back to a friendly one.
- Running Gag: People forgetting to call her Tiger, and her yelling them away. Her own club members, due to always respectfully calling her "president" are frequent victims.
- Super Strength: Implied. She can lift her massive bassoon with no trouble, but at least two of her fellow club members need to carry the thing. She later jams it into the ground and holds the top to keep herself in the air.
- Tiger Versus Dragon: The Tiger to Luke's Dragon. Additionally she is the Tiger to Asana's Dragon - or Wyrm.
The main character of Yu-Gi-Oh! Rush Duel Saikyo Battle Royale. They have the rare ability known as Spirit, that lets them connect with others through duels.
- The Ace: As typical for the game protagonists, they are an Instant Expert at Rush Duels and takes over as Protagonist.
- The Cameo: Appears in episode 60, bumping into Guruguru before running off to to Rush Duel with friends.
- Hello, [Insert Name Here]: As typical, their name is player chosen
- New Transfer Student: They come in the story sometime after many arcs have happened, such as the Garden of Providence.
- Small Role, Big Impact: His bumping into Guruguru leads him to finding the SEVENS storybook and bring it to Yuga and Co.
Goha Sixth Elementary (ゴーハ６小, Gōha Roku Shō)
Heavy Cavalry Duel ClubA duel club composed of elite students at Goha Sixth Elementary.
- Ace Custom: Their duel disks are contained within their construction equipment
- Dishing Out Dirt: With the exception of Chevelle, all of the characters who belong to the club use EARTH monsters in their deck.
- Good Old Ways: They dig for the origin and truth of dueling, and deride Rush Duels as a modern heresy. In addition, Asana hates drones, preferring more traditional machinery. They also feel this about their machine parts, as they refuse to use anything other than actual Mutsuba parts, that are unfortunately no longer made.
- HeelFace Turn: With Defeat Means Friendship, After Yuga beats Asana and reveals that Mutsuba did originally use alternate parts, the group stops their tyranny and embraces Rush Duels.
- Honor Before Reason: They refuse to use updated or alternate parts with their Heavy Machinery, as it is against their ways. The discovery of R0 shows this wasn't always the case, as the Mutsuba builders did heavily mod it with alternate and replacement parts. Afterwards, Asana drops the rule and they happily let Yuga fix R6 and the other machines.
- Horse of a Different Color: Instead of horses, their cavalry is their construction equipment.
- Kick the Dog: They brutally beat the previous student council and stole their cards.
- Military Mashup Machine: They ride construction equipment merged with military equipment that double as duel disks.
- Mythology Gag: Most of the Heavy Cavalry Duel Club use construction equipment, such as excavators, to Duel instead of the standard Duel Disks, reminiscent of the Duel Arenas used in the original series.
- Punny Name: Heavy Cavalry is a homophone of Heavy Machinery.
- The Rival: To the Dueling and Dinosaur Research Club, who they constantly push them out of their digsite.
- Tyrant Takes the Helm: Goha Sixth was originally a normal and fun school, but the club defeated the former Student Council, stole all their cards, and threw them out.
Asana Mutsuba (六葉アサナ, Mutsuba Asana)
Voiced by: Minami Takahashi
The heiress of Mutsuba Heavy Machinery, builders of Goha City. She plays a Wyrm Deck based around Mythic Sword Monsters.
- Action Girl: Asana is a skilled duelist capable of defeating Yuga in their first Duel, as well as even defeating Neiru without her own Maximum.
- Affably Evil: Despite her desire to end Rush Duels, Asana is unfailingly polite to Yuga when she meets him, and even legitimately thanks him for fixing R6. She also gets on well with her subordinates, who deeply respect her as well.
- All Girls Like Ponies: Parodied. She wears equestrian type clothes, but rides an excavator that she treats as though it were a horse.
- Anti-Villain: At the end of the day, she has no grudge against Rush Duels and even finds them fun herself. The main reason she's out to destroy them is because Goha promised to remanufacture the parts needed to repair R6 and the other Heavy Calvalry machines if she did.
- Arc Villain: Of the Goha Sixth Arc. She makes a deal with Goha Corporation to defeat Yuga and crush Rush Duels in exchange for parts needed to repair her clubs machines.
- The Bad Guy Wins: Literally. Her debut duel has her defeat Yuga in a quick and straightforward manner without needing Neiru's consistency manipulation, and following that, transfers Yuga and co. to Goha 6th Elementary.
- Bifauxnen: Asana is a slim girl with short hair, wearing a masculine though elegant uniform like a cavalry officer.
- Breaking Old Trends: Asana is the first rival character to be a girl, and she is the first duelist to use Wyrms instead of Dragons.
- Character Development: Comes to accept Rush Duels and modifying the Heavy Cavalry with alternate parts after her loss to Yuga, but she still hates Drones though.
- Childhood Friends: With Tiger, bordering on Pseudo-Romantic Friendship. A misunderstanding over Tiger thinking she was abandoned when looking for Luke on a snowy day - Asana and her great-grandfather had stumbled upon the half-frozen Kayama and Hatrap and took them to the hospital- leads to her seeking vengeance. Though once it is cleared up they resume their friendship and Asana apologizes.
- Companion Cube: She operates a digger she names R6, and treats like a horse she is affectionate towards.
- Daddy's Girl: Or rather Great-Granddaddy's Girl, as she was very close to her great-grandfather as a child.
- Dark Action Girl: The Arc Villain of the Goha 6th Elementary arc, and a skilled duelist.
- Dark-Skinned Blond: Dark-skinned with grey-white hair. It is a tan, as she was lighter skinned as a child.
- Didn't Think This Through: While her plan was executed flawlessly, its effectiveness leaves a lot to be desired, as noted by Goha. Asana's plan seems to have been to transfer Yuga and his friends to Goha 6th so she can crack down on Rush Dueling, but not only does this not quell Yuga's desire for the format at all, but as soon as he's transferred to the school he plays her like a fiddle to put himself in the position he wants.
- Don't Call Me "Sir": Galient and Chevelle assert on Yuga addressing her with respectful honorifics, but Asana tells them off as she is fine with Yuga simply addressing her by given name.
- Even Evil Has Standards: Despite defeating Yuga, she doesn't like that fact that she blindsided him with her Maximum Monster - after all, he assumed no one else had one. Thus she waited until Yuga regained his use of a Maximum Monster, assuming it would be Neiru's Yggdrago, to fight him fair and square.
- Failed a Spot Check: She doesn't realize that Luke is the same boy she knew from her childhood despite him not looking any different until she directly hears Tiger call him her little brother.
- Fatal Flaw: Asana favors Tradition over Progress, even if it costs her everything she loves. By being against modifications, she's unable to advance or improve her machinery and mindset, even when working for a corporation that refuses to cooperate with her.
- Foil: For Roa. Whereas the former is an extremely selfish individual who desires to be Duel King and gain Otes' approval in the process, while also having a bad habit of neglecting his companions (whether it be due to his arrogance or terrible communication skills), Asana is far more congenial, her goals seeming to be rooted in her family's history, and openly plans to destroy Rush Duels due to Good Old Ways, and she treats her subordinates well enough for them all to have Undying Loyalty to her.
- Forgotten First Meeting: It turns out she did know Luke from her childhood with Tiger, though she failed to recognize him as Tiger's little brother since she knew him by his first name and he was apparently calmer as a child.
- Friendly Rival: Towards Yuga despite being the Arc Villain, and with a slightly more serious rivalry from childhood with Tiger at first.
- Hidden Agenda Villain: Her initial backstory coupled with her rather lax attitude towards Yuga and developing interest in Rush Duels, very much muddied what her goals were. It is later revealed that, being a stickler for tradition, Asana was tasked with crushing Rush Duels in exchange for the old parts to repair a slowly malfunctioning R6.
- Machine Empathy: She can understand R6 and the machine language, but hates Drones for using regular speech.
- Not So Above It All: All of Yuga's friends present participate in his cosplay, but Asana was one of the few who weren't shocked by the notion, instead blushing.
- Ojou: A wealthy heiress, and is referred to as the Great Lady by her club. However, as Mutsuba is out of business, she is an Impoverished Patrician, with her Grandfather currently running a bike repair shop.
- Our Dragons Are Different: Plays Wyrm Monsters, which are mistaken for Dragons by Yuga and co., except for Luke, who recognizes them but admits he's not sure what the difference is.
- Power of Friendship: In her duel with Neiru, she adds the club's aces to her deck rather than take their ID cards to remake her Maximum. It is what allows her to win.
- Pride: The positive variant, where her pride of a Mutsuba and traditions is important to her, but later she admits her friends are more important to her than her pride.
- Ship Tease: She gets this with both Yuga and Tiger.
- She takes a quick liking to Yuga after he helps fix and compliment R6, and treats him with nothing but respect, even though she is actively trying to destroy Rush Duels. She's also shown to be quite perceptive of him after learning how he thought after their second Duel.
- She was instantly impressed by Haruka in their childhood and spent every day with her. The two have nicknames for one another that only they are allowed to use, and were depicted kneeling in a field of flowers while clasping hands.
- Student Council President: Downplayed. Officially, she is not the Student Council President of Goha 6th Elementary, but she has power equal to one once her club took over the school. Played straight in the time skip as she narrowly wins the position in the Goha 8th Middle School election over Gakuto.
- Tiger Versus Dragon: The Dragon, or Wyrm, to Tiger's Tiger.
- Tomboy with a Girly Streak: When the Goha Siblings bring in costumes for everyone else to help The☆Lukeman live out his adventures from Lukes manga, Asana is the only one other than Romin to look excited, if a little embarrassed, about it. In the next episode, she dresses up in a princess-themed costume, even calling herself The☆Princess Asana.
- Villainous Friendship: At the very least, her subordinates greatly respect her, and the feeling is mutual on her part. The villainous part is downplayed after her time as Arc Villain.
Galient Tazaki (田崎ギャリアン, Tazaki Gyarian)
Voiced by: Mitsuki Nakamura
Advisor of the Heavy Cavalry Duel Club. He uses an EARTH Machine deck based on Anti-Defense tactics, based around mechanical animals.
- Almighty Janitor: Despite dropping his advisor position after his loss to Gakuto, the rest of the club treat him with the same amount of authority and respect.
- Animal Mecha: His monsters are based around them, being transforming drills that turn into animals like bulls and his ace, Drilling Mandrill.
- Beware the Silly Ones: He's a sixth grader that dresses and styles himself to look like an adult, despite being short and stocky to begin with, but he's also a capable Duelist who flattens Ranze.
- Determinator: After losing GG03, he proves capable of still digging the same amount and will not stop serving Asana.
- Graceful Loser: After losing to Gakuto, he offers him his respect for being a master worthy of his servants, and quietly leaves Goha 6th. Gakuto and the Twins only failing to earn their freedom because Asana overruled it.
- Honor Before Reason: Despite GG03 being badly damaged, he refuses to stop the duel with Gakuto. And when he loses, he gives up his position and leaves Goha 6th as he is no longer worthy to serve Asana. Or rather the next episode shows that he is starting over as a grunt with just a shovel.
- Hot Blooded Sideburns: Sports a pair that shape a beard and a mustache, which fits his Hotblooded military aesthetic and older feeling.
- Maniac Monkeys: His ace monsters, Drilling Mandrill and Shield Boring Kong, are based on monkeys and apes.
- Old Retainer: In spirit if not age, as his Undying Loyalty to Asana, is like an Old Soldier dealing with their younger liege. He is old enough to have given a toddler Asana baths. His family appears to have been in a Legacy of Service to hers as well.
- Old Soldier: Not helping his status, is that he talks like one, referring to everyone as Youngins.
- Powerful Pick: After the loss of GG03, he goes back to basics and uses a pickaxe to dig everywhere. While he doesn't fight with it, he is still a Tunnel King with it.
- Stout Strength: Despite his stocky appearance, when he ditches his jacket after his loss, he is revealed to be incredibly ripped and strong for his age.
- This Is a Drill: Aside from digging, his monsters have a drill theme.
- Took a Level in Kindness: His first appearance showed him willing to be underhanded, but after his loss to Gakuto, he refuses to allow his comrades to use dishonorable methods.
- Tunnel King: Proves capable of tunneling from Goha 6th to Yuga's base with only a pickaxe, and later tunnels all the way to the Machine Cavalry Colosseum - the latter of which leaves him too tired to stand and he passes out.
- Undying Loyalty: To Asana, whom he considers the Great One.
- Vague Age: Initial reports described him as an elementary schooler trying to look and act grown-up, but he's later revealed to be significantly older than Asana despite remaining in sixth grade. His true age is unclear.
- Younger Than He Looks: Though he's an elementary schooler, he stretches the sideburns on his hair such that they're shaped like a moustache, so as to look more like a grown-up, and also talks like an elderly man. Subverted when it he turns out to be older than he looks, making him an adult pretending to be an elementary-schooler...pretending to be an adult.
Chevelle Kayama (加山シュベール, Kayama Shubēru)
Voiced by: Yugo Sato
One of the three members of the Goha Sixth Elementary elite trio. He is accompanied by his companion pigeon, Hatrap, and is capable of understanding him. He uses a Winged Beast Deck, with a focus on Trap Cards to manipulate ATK values and dealing burn damage.
- Aristocrats Are Evil: He's dressed the fanciest of the group, and is an antagonist, so he fulfills this quite well.
- Cloud Cuckoolander: He's a bit weird with his pigeon, and was apparently raised by Pigeons, so Hatrap is his brother.
- Dark and Troubled Past: He apparently used to be a huge crybaby that Hatrap had to look over, and at some point as a child, was caught in an avalanche and would've died along with Hatrap had Asana and her grandfather not saved them.
- French Jerk: He has elements of this, being thus far the only member of the Heavy Cavalry Duel Club without any redeeming traits and calling Galient "Monsieur Galient", in addition to his name sounding French. He's also the most condescending and rude to Yuga's group, and enjoys taunting Luke throughout their duel.
- Idiot Ball: Decided to summon a second copy of his ace monster in Attack Position on Luke's turn. This is despite the fact that Luke's tactics include ATK reduction on top of heavy-hitting dragon monsters. Hatrap, for his part, immediately notices it and starts pecking and squawking at Kayama for such an idiotic play. Had he summoned out Phantom Dove in Defense Position, they would have survived Luke's final offense.
- One Degree of Separation: The avalanche incident lead to Asana and Tiger's friendship fracturing and they only stumbled upon him to save him because they were looking for a missing Luke, who was completely fine.
- Pet the Dog
- Is greatly concerned for Galient after he dug so far with only a pickaxe, and is alarmed when he passes out.
- He cares very deeply about Hatrap, saving the pigeon after Luke deals the finishing blow, and this was after they had a spat.
- Raised by Wolves: Or Pigeons, who somehow were capable of running a delivery company.

An assassin that works for the Machine Calvary Club and oddly resembles Noodle Sorako. She plays a Pyro deck of FIRE and EARTH monsters with an acupuncture theme.
- But Now I Must Go: After defeating Sebastian, she has to go back to her people, to the confusion of Kayama.
- Cute and Psycho: Despite being chipper like Sorako, she shows a nastier side, calling Kaizo a fly and not showing any remorse over breaking Sebastian.
- Exotic Eye Designs: Her eyes have triangular highlights, unlike the stars in Sorako's.
- Hero Killer: Defeats Sebastian in a duel, which causes him to shut down.
- Identical Stranger: Is one to Sorako complete with the ability to withdraw inside her drill just like how Worako is able to do that with her spaceship.
- Magma Man: Her EARTH and FIRE monsters are lava-based animals.
- Mistaken Identity: Sebastian assumes that she and Noodle Sorako are the same individual, but she denies knowing anybody by that name.
- Mole Men: A figure from the Shiatsu Empire, which is some sort of Mole Men Empire.
- Psycho for Hire: A light and soft example, but still a hired assassin that is mildly Cute and Psycho.
- Pyrrhic Victory: While she won the duel against Sebastian, he was still able to buy enough time for Kaizo to escape and contact Neiru.
- Suspiciously Specific Denial: While it's not clear if she is Sorako, she definitely knows about her, claiming that after Sebastian asks if she is Sorako that she totally isn't that space alien whose name means "Sorako".
- This Is a Drill: That she does acupuncture with, and like Sorako's saucer, she can put herself inside the drill.

A member of the Machine Calvary Club who tries to dismantle Yuga's Road Laboratory. He uses an EARTH Beast deck.
- Meaningful Name: His surname contains the kanji for "elephant", and one of his monsters is an elephant. After being beaten, he briefly responds to Haruka by making elephant noises.
- No-Nonsense Nemesis: He seems to realize in his debut that demolishing Yuga's lab doesn't require he duel anyone, scaring off Yoshio and his friends when they try to stop him and then outright trying to run over the Newspaper Club without even entertaining the idea. The only reason he duels Haruka is because she's strong enough to force him into one.
- Sore Loser: He refuses to acknowledge his loss against Tiger and attempts to dismantle Yuga's Road Laboratory, until Galient intervenes and dissuades him from going through with it.
- The Stoic: He's fairly hammy during his debut, but later tries to present himself as a lot more stoic behind his mask.
- Stone Wall: His monsters all have high defense and low offense (with his field spell boosting their defense but lowering their attack even further), and his strategy is to stall in defense mode and hit the opponent with traps to force them to damage themselves by attacking his defense monsters. He also incorporates Sword and Shield to take advantage of this for some offensive power.
Voiced by: YouthK Saeki
He uses an Insect Deck based around Rebelling Ants. His deck resolves on swarming the field with low-attack monster in order to strengthen them with his ace card Antbellion of the Rebellion.
- Animal Motifs: He compares himself and the other former student council members as ants since they are both small oppressed beings living under everyone's radar.
- Big Creepy-Crawlies: His deck is comprised of Insect-Type monsters or to be more specific ants.
- Expy: With his Insect and Rebellion theme, he is a Lighter and Softer version of Shinji Weber from Yu-Gi-Oh! ARC-V.
- Hypocritical Humor: He does this twice in the meeting between Goha 7th and 6th to counter Fusion, first telling off Botan for losing control and eating everyone's food while he himself has a hand deep in a box to soothe his drawing trauma, then claiming Gakuto isn't distinguished while he himself is pretty dishevelled and prone to having his seizures at inappropriate times, something Gakuto points out to him.
- I Can't Believe It's Not Heroin!: He is addicted to drawing cards, which is why he loves Rush Duels so much.
- Meaningful Name: His surname comes from an extinct branch of the Japanese Imperial family, highlighting his status as the former Student Council President, while the first character also happens to be a homophone for the Japanese word for "ant", tying into his animal motif.
- Mythology Gag: His "Gi-Ant Revolution" deck is a parody of the "Huge Revolution" archetype of cards back in the early days of Yu-Gi-Oh, with all the people in the artwork storyline being replaced with ants. Unlike that archetype though, Jango's deck was reworked so that the cards are actually playable in a realistic duel.
- Rebel Leader: Of the Goha 6th Resistance, though unfortunately he's really not a match for the sheer numbers the Heavy Cavalry Duel Club has, easily forcing his rebellion's end, and him to rejoin the school.
- Schmuck Bait: Part of his strategy is to summon a bunch of monsters with only 100 ATK in order to bait the opponent into attacking and then punishing them with Trap cards.
- Student Council President: He was originally this to Goha 6th Elementary until the Heavy Cavalry Duel Club forced him out. After the Goha 6th arc, he's returned to his position.
Other Schools and Friends
Voiced By: Daisuke Nagumo
A student of Goha 3rd Elementary who loves ramen and seeks to create a set of Dueling rules that unites Dueling and ramen.
He uses a Pyro Deck focusing around the Masked Fiery Noodle series. His deck revolves around gathering normal monsters in the graveyard to strengthen Pyro monsters on the field.
- Antiquated Linguistics: Befitting of his ninja motif, he adopts an old-fashioned manner of speech when addressing others.
- Berserk Button: Do not tell him that you prefer udon over ramen, saying such is enough for him to challenge Yuga to a Duel. And when Luke eats the last ramen, he drops his formal speech and outright calls him "kisama".
- The Bus Came Back: He returns in Episode 11 with two companions of his own to provide catering services to Roa's concert.
- Dub Name Change: To Saburamen in the English version of Yu-Gi-Oh! Rush Duel: Dawn of the Battle Royal.
- Friend or Idol Decision: Has one of these during his duel with Sorako: lose to her and get to experience cuisine in outer space at the cost of giving Yuga and his friends a penalty, or win and disable her UFO but not cause problems for his new friends. Ultimately he chooses the later. This ends up being surprisingly important in the end, since Yuga and co. end up with five penalties when all is said and done, meaning their accounts would have all been banned had he acted more selfishly.
- Fire Is Red: Fitting for a Pyro Duelist, his color scheme is predominantly red.
- Glass Cannon: Masked Fiery Noodle Jonin Gockboot, his ace monster, is one as it has 2200 ATK but 0 DEF. This weakness ends up leading to his defeat in his Duel against Yuga when the latter uses spell cards to change Gockboot to defense position and give Sevens Road Magician the ability to inflict piercing damage, allowing him to deal enough damage to win.
- Hot-Blooded: Extremely bombastic and dedicated to his love of ramen.
- Ninja: The Masked Fiery Noodle monsters are ninja with a ramen-themed aesthetic.
- Playing with Fire: All Masked Fiery Noodle monsters are Pyro-type and FIRE. Notably, he's the second Duelist in the franchise to specialize in the use of Pyro monsters, following Austin O'Brien/Axel Brodie from Yu-Gi-Oh! GX.
- Trademark Favorite Food: Ramen, of course.
- Unwitting Pawn: Oblivious to Roa's true nature, he happily provides catering for Roa's concert... which serves to trigger Romin's hunger-crazed berserk state. He and his friends apologize in the next episode for having done so.
Voiced by: Yuki Sakaihara
A student from Goha 2nd Elementary, president of the Dueling and Dinosaur Research Club that seeks to explore the relationship between dinosaurs and dueling.
He plays a Jurassic Deck, made of WATER Aqua monsters based on prehistoric sea creatures and EARTH Dinosaurs, referencing the evolution of earth.
- Adventurer Archaeologist: Or rather Paleontologist, where his desire to make money off of dinosaurs reflects the more aggressive Bone War archeologists, whereas his restored romanticism and adventurous spirit reflects modern appeals.
- Affably Evil: Of Affably Antagonistic, where even when using Yuga he is softspoken and polite. He returns to being more of a Nice Guy once Yuga beats sense into him.
- The Alleged Boss: Downplayed, but in the club he is content to sit back and let his Number Two, Kaseki make most of the decisions. And then he and Kaseki let Hunt push them around during his Acquired Situational Narcissism
- Badass Bookworm: A scholarly individual, and still a powerful duelist with a T. rex.
- Breaking Old Trends: Previous dinosaur duelists tended to be Hot-Blooded Jocks, Bullies, or evil, while Hakubutsu is instead a polite, well-spoken romantic scholar... and his desire to make a profit off of dinosaurs is quickly corrected by Yuga, who restores his romanticism towards them.
- Can't Catch Up: Noted in Episode 45, that despite being a match for Yuga early on, he and Kaseki are no match for Roa or Neiru.

- Demoted to Extra: Despite being the original Sevens Dinosaur duelist, Hunt overshadow him in later arcs, while he ceases to be relevant.

- Goggles Do Nothing: He wears a pair of goggles with blue frames and a red rim on his forehead.
- Greed: Desires to make a profit off of dinosaurs, but Yuga fixes that.
- Labcoat of Science and Medicine: Wears one over his clothes, lending to his more scholarly appearance.
- Making a Splash: The first half of his deck, prehistoric sea creatures such as the trilobite.
- Prehistoric Monster: Typical of any Dinosaur duelist, but Hakubutusu ups the ante by including prehistoric sea creatues.
- Punny Name: His full name, Hakubutsukan is the Japanese word for Museum.
- Took a Level in Idealism: After his defeat by Yuga, his romanticism is restored, and he becomes an ally to Yuga and Co.

Hunt Goto is a student at Goha 2nd Elementary, and he is a member of the Dueling and Dinosaur Research Club under Kan Hakubutsu. He possesses a rare ability to sneeze when finds are nearby. He plays a LIGHT Dinosaur deck related to material wealth, known as the Nouveau Riche Dinosaurs.
In the Goha Rush Tournament, he is responsible for distributing Maximum Cards after making a deal with Goha 66.
- Acquired Situational Narcissism: After finding a hoard of Maximums and selling them, he makes a lot of money, and becomes extremely vain and materialistic, even pushing around Hakubutusu and Kaseki, making them carry him on a palaquin throne. He even dyes his hair blond, and dresses in gaudy gold clothing. However the Narcissism lasts, with him permantely being a rude jerkass.
- Adventurer Outfit: A safari outfit with a dinosaur painted hard-hat.
- Angry, Angry Hippos: His ace, Zenigebazauls is a hippo-based dinosaur with a Morally Bankrupt Banker theme, that can deal damage to the opponent after he gave them lifepoints with Upstart Goblin.
- Ascended Extra: Originally a sidekick of Kan, he becomes prominent due to his ability to find Maximums and making a deal with Goha 66.
- Big Damn Heroes: When the heroes are lost in Maximum Mountain, he comes to their rescue with fresh drinking water, when Romin was about to drink possibly poisoned water.
- Bitch in Sheep's Clothing: Despite being the most openly eager of the Dinosaur Club, he is the most duplicitous of the group, though he also panics when his sneakiness is revealed. Later episodes have him as more of The Cutie. Though averted as it turns out he was the only one that didn't learn his lesson last time and acts like a major Jerkass to his friends and others with his materialistic nature.
- Card-Carrying Villain: More like Card Carrying Jerkass, but by the Goha Employee Arc, he acts in a smug Weevil-like manner, completely open about his greedy and dark nature.
- Cheaters Never Prosper: He sold Maximum cards one-at-a-time so no one had a complete set, despite his use of Great Imperial Dinocarriage Dynaramix. Naturally he loses because he didn't expect Yuga to be able to come up with his own second Maximum thanks to Neiru, Roa, and Asana.
- Chekhov's Gunman: In the first arc, he is simply Kan's sidekick, but in the Goha 6th Arc his sneezing ability is invaluable for finding Maximums.
- Cool Chair: A golden chair that turns into a Jurassic stone one under the effects of Jurassic World.
- Deal with the Devil: Goha 66 helped him find all the Maximum cards in exchange for Hunt finding something for him.
- Dishing Out Dirt: Great Imperial Dinocarriage Dynarmix is EARTH unlike his other monsters.
- Easily Forgiven: By his friends for treating them like dirt after his defeat by Yuga, even though it is shown he hadn't learned his lesson.
- Embarrassing Nickname: Not his name, but he doesn't like Luke naming his ability Sneezcavation.
- Everyone Has Standards: Despite his Greed, he has enough sense to not sell off his own Maximum Monster, since it is still incredibly useful.
- Gem-Encrusted: His LIGHT dinos have this theme.
- Giant Equals Invincible: Dynarmix cannot be destroyed by Traps Cards or in battle with Level 7 or lower monsters, effectively necessitating another Maximum to beat it.
- Gold Makes Everything Shiny: Dresses in gaudy gold clothing with rings and blond hair after becoming rich from selling maximums.
- Greed: The greediest of the bunch, especially when he becomes the Maximum seller, and at the end of the episode, he still finds money to be more important than dueling, though his friends don't let him finish. It is reflected in his non-Maximum ace, Zenigebazauls, as the term Zenigeba is a Japanese term for a money-crazed person.
- Light Is Not Good: His LIGHT monsters reflect gold, and he duels with them during a massive jerk phase.
- The Nose Knows: Is capable of smelling out finds, whether the Relic, fossils, or the prototype duel disks.
- Nouveau Riche: Dresses gaudily, treats everyone like garbage, and acts crass all around after becoming rich. His series is even known as Nouveau Riche Dinosaurs.
- Powerful Pick: Wields one with enough power to smash through a wall and Yoshio's Good Max costume.
- Smug Snake: His Maximum Monster makes him rather convinced of his power, and he acts in a Weevil-like manner, being rude and hostile to everyone.
- Too Important to Walk: He is carried on a palaquin throne by his friends in episode 45, and this is reflected in the Great Imperial Dinocarriage Dynarmix, as it is a city-sized dinosaur pulled by two smaller dinosaurs that represent Kan and Kaseiki.
- Took a Level in Badass: A dark version, going from Kan's sidekick to the fourth Maximum user, capable of getting his team to third place in the Goha Tournament. However averted with the Goha Employee Arc, where he fails to find a Fusion and his Smug Snake nature becoming worse causes him to be trounced by Bakuro's fusion.
- Took a Level in Jerkass: After he becomes wealthy from selling Maximums he rises in social standing among his friends and outright admits he would trample on them. And then he becomes even worse come the Goha Employee Arc.

Nick uses a FIRE Beast Deck based on Barbeque and older monsters like Battle Ox related to boosting their attack points.
- Action Girl: Sushiko is a skilled duelist capable of beating Romin.
- Americans Are Cowboys: Thematically, since Nick appears to still be Japanese, though his cooking wouldn't be out of place at a Texas Roadhouse.
- Foil: Sushiko is this to Romin, being a prim and proper lady compared to Romin's rock-star theming. Her deck, in a similar vein to Romin, also works by LP manipulation, but focuses on increasing the LP of the opponent to increase the differences to fulfill effect conditions, as opposed to Romin's which focuses on decreasing her own LP to use effects.
- Hot-Blooded: Nick, as befitting a FIRE duelist, though not quite to the same Large Ham extent as Menzaburo, instead being more of slow to cook until he becomes a raging fire, fitting his cooking style.

- Not So Above It All: Sushiko presents herself with poise and elegance... and she also fights with Romin over the remote.

He plays a Fish deck entered around supporting his lower-level monsters by reducing the ATK of opposing monsters with his field and trap cards or by having his ace monster give them the ability to attack directly, and recycling cards from his graveyard for later use.

- Defeat Means Friendship: When Yuga defeats him, Maguro realizes he isn't the type to litter and even gets Yuga and co. back to land after Fake Kaizo tricked them onto the boat in the first place.
- Expy: Of Mako Tsunami/Ryota Kajiki from DM, being a fish duelist, and even has a similar color scheme and deck. He is however much Lighter and Softer as he lacks a tragic backstory.

- Green Aesop: He hates it when pollution the sea, and his deck even has a mild recycling theme to it, the gang even calling his deck eco-friendly.
- Making a Splash: He uses a Fish deck composed entirely of WATER monsters.
- Out of Focus: Unlike most characters seen in the series, Maguro has very few appearances outside of his debut due to being on Goha Fishing Elementary. He eventually made a small cameo over forty episodes later, having met with Yujin Goha and begun fishing with him. And then in the final arc he brings copies of the SEVENS book from all over the world to Yujin so they can finish the story.
- Punny Name: His name literally translates to "tuna of the seven seas".

Braun Honya is a student at Goha 5th Elementary, president of the Space Operations Duel Club. He seeks out his own Maximum Monster. He plays a Reptile Deck based on spaceship turtles, with a strategy of manipulating his opponent's monsters levels and attack.
- Cloud Cuckoolander: He and his friends are just plain weird, to the point that even the Heavy Cavalry Club are weirded out by them. They line a mineshaft with lights to pretend that it's outer space, carry a ladder around with them for Braun to descend like Neil Armstrong, and are pretty much constantly quoting space-related media.
- Graceful Loser: After losing to Luke, they all happily look for ID cards together. After Neiru defeats Braun he also happily admits how amazing Yggdrago is.

Nanaho Nanahoshi is the President of the Dueling Insects Club of Goha 5th Elementary, as well as the cousin of Ranze and Rinnosuke. She is a childhood friend of Yuga's, and the reason for his fear of Ladybugs. She seeks to steal the secrets of Maximums... but her actual goal is to restore Yuga Goha.
Nanaho plays an Insect Deck of Ladybugs, that utilize swarm, defensive, and burn strategies like her cousins.
- Animal Motifs: Ladybugs, with an insect motif extending to her underlings who are a beetle and preying mantis.
- Arc Villain: Of the Goha Employee Arc. Yuo is still active and wanting to crush Rush Duels, but he is busy consolidating his control and actually doing his job while she takes center stage.
- Ascended Extra: Although her club appeared at the Training Camp and Rush Duel Tournament, the Goha Employee Arc raises her to prominence.
- Big Creepy-Crawlies: Her evil ladybugs.
- Bitch in Sheep's Clothing: She'll use tears and cutesy behavior to get her way, but is Cute and Psycho.
- Chaos Is Evil: Like Yuga Goha she seeks to spread chaos and destruction.
- Charm Person: Is able to charm Guruguru into leading her to Yuga.
- Childhood Friends: With Yuga, though he fears her. For a definition of friends, since even then she was somewhat of a bully to him.
- Cute and Psycho: Acts cute, even being a Third-Person Person, but is in reality a manipulative and sinister person.
- The Dragon: To Yuga Goha, who she was working to unseal from Swirly.
- Enemy Mine: She opts to screw with Otes by causing all the Ko Girls to leave him in the final battle, out of revenge for him and them making a fool out of her than any real desire at redemption, which saves Yuga and Co from an immediate loss.
- Evil Costume Switch: From rather cutsey clothes to ninja clothing with a mask that makes her look sinister.
- Evil Former Friend: Downplayed since even in childhood she was a bully.
- Evil Princess: Despite her princess and fairy tale motifs, she is rather sinister.
- Fairy Tale Motifs: Her humanoid monsters have this, being based on princess characters.
- Giggling Villain: She laughs in her Na Verbal Tic whenever she is being smug and malicious.
- Light Is Not Good: The majority of her monsters are LIGHT and she uses Forest of the Sun, though Malefi is DARK.
- The Lost Woods: Although Forest of the Sun is pretty, it invokes this with the Sleeping Forest of her ace, Malefi Ladybug of the Sleeping Forest. Malefi is even a pun on Maleficent.
- Master of Disguise: She is able to flawlessly disguise herself as Romin to trick everyone, which only fell apart because Asana bumped into Romin separately.
- Nice Hat: A Ladybug, that is possibly evil and sentient.
- Ninja: As a Nanahoshi branch member, she has ninja training and can pull a Smoke Out.
- Shadow Archetype: She and her family are as a whole this to the Main Nanahoshi branch, sowing chaos and destruction from the shadows.
- Verbal Tic: Na, which she especially uses when feeling smug.

The President of the Goha 4th Duel Zombie Club, hired to run the Zombie Party.
He plays a Zombie Deck themed on dance.
- Dark Is Not Evil: Although he seems like the episode villain, he's just a hired actor for the Zombie Party.
- The Dead Can Dance: His zombies are themed on zombie dancers, like a Venice Carnival or Samba.
- Elite Zombie: Invoked, he is the Final Boss of the episode, and talks unlike everyone else pretending.
- Frankenstein's Monster: His ace, Cyber-Stein Shrine, which Gakuto complains that Frankenstein is a different genre.
- Glass Cannon: His zombies have high attack, but low defense like most Zombie monsters.
- Michael Jackson's "Thriller" Parody: He dresses like one with an afro, jacket etc, though his monsters are themed on other dances too.
- Mythology Gag: His appearance with makeup makes him look like Bonz dressed like Michael Jackson, and the Duel Zombie idea comes right from Season 3 of GX.
- Zombie Apocalypse: Or rather, Gakuto thought this was the case since the episode plays like a Zombie Horror Movie, but it turns out it was just a quirky recreation event for Goha Corp.
RoaRomin (ロアロミン, Roaromin)The indie band led by Roa Kirishima.
Roa Kirishima (霧島 ロア, Kirishima Roa)
Voiced by: Kazuki Furuta
Romin's cousin and the leader and singer of RoaRomin. He has an interest in "Rush Dueling". He plays a Fiend Deck focusing on the Royal Demons, with his strategy revolving around hand and field destruction.
- Affectionate Nickname: He calls Getta Getta-chan, Yuga Yuga-chan, and Neiru Neiru-chan, Genius-kun, and "Providence-chan".
- Ambiguous Disorder: Shows many traits consistent with Narcissistic Personality Disorder, including a sense of entitlement and self-importance, lack of empathy for others, a manipulative and exploitative personality, and a need to be the center of attention at all times, likely stemming from his The Unchosen One status.
- Analogy Backfire: Comparing Getta and Ushiro to the aces he sacrificed to Summon Royal Demon's Death Doom, did not convince them he really wanted to make up to them, despite the fact that Death Doom would have only been a beatstick without them. Reversed in his duel with Romin where he uses the aces to revive Death Doom, the three standing together as equals, with Getta and Ushiro being touched by the gesture.
- Arc Villain: Of the Birth of Rush Duels arc. He sets up a best-of-three match with his band against Yuga's friends, unlike the previous opponents who were antagonists for a single episode. Likewise, he's the one who has ordered Romin to spy on Yuga's group, giving him a greater role in that regard.
- Attention Whore: Called this by Romin, who notes that he always liked to stand out.
- Badass Normal: Explicitly noted. Most of his monsters are Effect monsters and he is the only one of the seven main characters to lack either a Maximum or a Fusion. This doesn't stop him from defeating Asana when she had a fusion and Yuga when he had both.
- Big Brother Bully: Downplayed. He and Romin are usually friendly towards one another, but during the Birth of Rush Duel Arc, he blackmails her into do his dirty work, and pins her against the wall reminding her that if she listens to him he won't reveal her secret. He also had Getta eat all the food backstage to deliberately starve her, knowing it would trigger her Superpowered Evil Side so shed duel better.
- Bitch in Sheep's Clothing: He acts like a charming singer, but it hides his manipulative nature and emotional abuse of his cousin, and he very likely does not have good intentions in mind for the other protagonists. Fittingly, his deck is made up of LIGHT Fiends. He grows out of it as the series progresses.
- Character Development: Goes from a selfish, egotistical duelist, to a more social and appreciative duelist who, while still egotistical, is shown to have a legitimate set of standards.
- Chick Magnet: All of the elementary school girls and Mimi swoon over him when he is on stage.
- Childhood Friends: With Getta, whom he calls Getta-Chan.
- The Chosen Wannabe: With a bit of The Unchosen One, he is upset that Otes chose Yuga over him, and so he made his own road to break up the world's rigidity. Had he beaten Yuga, Otes would have accepted him as the new chosen king.
- Composite Character: He takes on a lot of similarities to IV from Yu-Gi-Oh! ZEXAL in his character, but also has a slight king motif like Jack Atlas from Yu-Gi-Oh! 5D's and uses a Fiend deck like Reiji Akaba did in Yu-Gi-Oh! ARC-V, though his are LIGHT, not DARK.
- Contrasting Sequel Antagonist: Compared to Ryoken/Revolver, the previous rival. Where Ryoken was a Well-Intentioned Extremist trying to protect everyone with a measure of humility after the fact, Roa is Driven by Envy and significantly pettier, being mainly interested in himself and with an ego to match. While Ryoken dedicated his life to his father's dreams and wishes, Roa's dreams are entirely his own. Ryoken's plans ultimately caused a stagnation of sorts in Duel Monsters, due to the Knights of Hanoi almost completely destroying the Cyberse type and terrorizing Link VRAINS, whereas Roa desires to push Duel Monsters forward, being very interested in Otes' legend, while Ryoken tried his hardest to kill the Ignis, having no interest in their potential whatsoever. While Ryoken deeply cared for the core members of the Knights of Hanoi and had a very close, albeit static bond with them, especially when they shifted to a more heroic role, Roa treats his friends like dirt, causing them to get fed up and leave him, until Roa learned to not be so much of a jerk. Finally, whereas Ryoken and Yusaku had a very personal relationship throughout their series, Yuga was completely ignorant of Roa's existence, and generally passive and understanding of his goals and motives, only coming into conflict with Roa through coincidences.
- Disappointed in You: Roa very much wanted to duel Luke, seeing him as a very strong and Worthy Opponent. Seeing Luke lord his president status over everyone and brag about it while dueling gives Roa this reaction, and he wastes no time lambasting Luke for it. Unfortunately for Roa, the speech does not sink in for Luke the way that an enraged lambasting fired up Yuga. Luke is too attached to wanting to be president than register that he has sacrificed his duelist's honor, and the resulting comeback is born out of a desire to win to prove that he is president, rather than realize that he has likely been manipulated or that he betrayed his companions for power and influence.
- Driven by Envy: His antagonism towards Yuga is born from his resentment that Yuga was picked over him by Otes. Ironically, he has his own envier in Getta.
- Dub Name Change: His surname is changed to "Kassidy" in the English version of Yu-Gi-Oh! Rush Duel: Dawn of the Battle Royal.
- Everyone Has Standards: Roa, for all of his ego, takes a duelist's character very seriously, being furious of Yuga's blaise dismissal of his loss to Neiru when it should be enraging and increasing his drive, and being disappointed in Luke for turning against his friends and lording his new status as a Goha President over everyone else, even though he had wanted to duel Luke because of his strength.
- Faking Amnesia: Played for Drama, Roa like Luke survived Goha Yuga's attempts to erase his memory because like Luke he had a strong bond with Yuga before Rush Duels. However because he was tired of not being chosen by Otes and Romin being chosen for a solo debut, he opted to fake it for the chance of a new start as a musician. Yuga and his fans break him out of the funk, and he even defeats Yuga in the resulting duel.
- To Yuga. Both desire to break down the stagnant nature of dueling, but Yuga is For Happiness, while Roa's goal is To Be a Master. Yuga is a Nice Guy, whereas Roa is a Bitch in Sheep's Clothing. Yuga is a very humble child, while Roa is a glory hound.
- To Luke as well. Both of them, to a degree, fit The Rival archetype as seen in the franchise, but Luke is closer to Jounouchi and Manjoume in terms of temperament and is one of Yuga's friends, while Roa is just as malicious as Death-T Kaiba and the first of Yuga's really serious foes. Even better, Roa later gets Character Development in learning to truly appreciate his bandmates and what it is like to handle being a skilled duelist, while Luke has a FaceHeel Turn borne solely of his ego that has never taken a permanent hit.
- Get a Hold of Yourself, Man!: He chews out on Yuga for musing over his devastating loss against Neiru and brushing it off as an instance of bad luck.
- Giver of Lame Names: He presents his team's name as "Roa and Getta and Ushiro" for the Team Battle Royal. Both Gakuto and Romin comment that he has zero naming sense.
- Graceful Loser: He takes his loss against Yuga in stride, and looks forward to dueling him again in the future. Though Yuga and his friends think that he is just putting on a brave face to look good in front of the fans.
- Hidden Agenda Villain: He seems to have plans regarding "Rush Duels", and while he claims that he just wants to claim their copyright, there's the fact that he had Romin whisper the urban shrine legend to a sleeping Luke and didn't make a move until after the format became fairly well-known. His plans are also unknown to Goha, judging by Mimi's reaction to his goals succeeding. His plans are revealed to be that he wants Otes to acknowledge him as Duel King, upset that he didn't give him Sevens Road all those years ago.
- Hidden Depths: The credits to episode 44 reveal that Roa is a good cook, explaining why his apartment is so well-stocked with cooking equipment from Romin's ramen attempts.
- Hoist by His Own Petard: His constant milling of Yuga's deck to force him to draw Sevens Road Magician backfires, as his disqualification strategy is derailed by the time Yuga actually draws it. Yuga is then able to use Sevens Road Mage to depower his ace using all the Spellcaster monsters Roa forced him to discard, at the same time allowing Sevens Road Magician to reach its full potential thanks to milling all six attributes, winning the duel.
- I Am Not Left-Handed: He uses an underhanded disqualification strategy against Yuga to disgrace and make him lose without having to battle him seriously, but when that plan falls through, it's shown that he's actually an extremely competent duelist.
- Innocently Insensitive: Due to his selfish behavior, he fails to realize how badly he alienates Getta and Ushiro, and even after Romin lets him know what he did wrong, his pride doesn't let him go apologize.
- It's All About Me: Roa loves to steal the spotlight for himself every opportunity he gets. He also has a habit of referring to himself with the arrogant "ore-sama" first-person pronoun. However his tendencies towards this pale in the face of Luke's.
- He duels Yuga with ownership of "Rush Duels" on the line, with the selfish intent of renaming it to "RoaRush Duel", and attempt to disgrace him for using the supposedly illegal Sevens Road Magician.
- While he genuinely wants to Duel with his friends in the Goha Rush Duel Team Battle Royal, he once again places his desire to duel Mimi for the chance to talk with Otes above the wishes of his friends, not even telling them he planned on doing so and alienating them.
- Jerk with a Heart of Gold: Downplayed. He does care about his friends, particularly Getta, even if he is rather self-centered and not the best about showing it, to the point that after he realizes that he hurt Getta's feelings when the others reveal he commissioned Yuga for a drumming bot, he decides to ask Yuga for a drumming duel disk for Getta instead.
- Karma Houdini Warranty: Played for Laughs after getting off pretty much scot-free for his manipulative behavior and Arc Villain status, Episode 14 sees Romin managing to flood his entire apartment complex with her blue curry. Later on, his It's All About Me attitude causes his friends to leave him, and he has to properly learn about being respectful of their feelings and wants afterwards.
- Large Ham: He duels very dramatically, using concert effects and having Ushiro and Getta stand behind him with flashlights to give him a Holy Backlight. Notably all of his high-Level monsters often have a short summon chant in addition to the more traditional long ones for his ace monsters.
- Leitmotif: "Miniscape", which also serves as the Insert Song and special ED of the second half of his duel against Yuga.
- Light Is Not Good: His monsters have the LIGHT attribute, but they're all Fiends.
- Manipulative Bastard: Oh, yes. He has manipulation ready for everything he does to gain even the slightest advantage.
- Took advantage of Luke's tendencies to believe in Urban Legends to essentially kickstart the whole plot, and may have further plans beyond even that. He also uses this against him during his duel with Ushiro by having Ushiro scare Luke before and during the Duel.
- He manipulates his cousin to spy and duel better, by having Getta eat all the food at the concert so Romin gets hungry, even having Menzaburo and his friends bring food stalls into the concert.
- He questions Seven Road Magician's legality and then has his fans slam Goha with questions to force them to respond, and when Goha decides Yuga can continue the duel as long as he doesn't draw it, Roa uses hand destruction and cards to force Yuga to draw so he risks doing so.
- Not-So-Harmless Villain: After all his dirty tactics, once he starts dueling seriously, Yuga and co. are surprised at how dangerous he actually is as a duelist.
- Not So Stoic: After coming to relieve Romin of house-sitting his apartment, he understandably loses it upon seeing it flooded.
- Out of Focus: After briefly helping in the Maximum Arc, he sits the Goha 6th Arc out, not making an appearance, though he returns for the Team Battle Royale Arc.
- Perpetual Smiler: He's almost always smiling in a smug and malicious/creepy manner.
- Poke the Poodle: While his actions are harsh - his manipulation of Romin by merely holding that she can't sing over her as blackmail is this.
- The Rival: He's the first one of these set up in the series for Yuga, not counting Luke being more of a Friendly Rival, and the one with the most ties to previous rival characters in the series. Notably he's the only character acknowledged by Otes as one who could also become the King of Duels and he's the most proactive character behind Yuga in finding out what's going on. He becomes the first out of the rivals to beat Yuga in their rematch, not counting Luke and Yuga's duel after the Lukeman duel that Yuga won.
- Secret-Keeper: Downplayed. Roa keeps Romin's secret...of her being tone-deaf in the dark, so long as she listens to what he says.
- What the Hell, Hero?: He is pissed seeing Yuga's Dismotivation traits pop up after his defeat at Neiru's hands, grabbing him by the collar and yelling at him for it. He has a more disappointed variety for Luke after Luke is convinced by Yuo that he is the sixth president. Roa is disappointed that Luke, for all his strength, has now sunk to just lording a status over others.
- The Worf Effect: Happens to him in Dawn of the Battle Royale, where he is crushed by Nail and his Maximum to set the stakes the Protagonist has to deal with, since the previous Garden of Providence Arc happened before the Protagonist got there.
Voiced by: Ryo Takizawa
The uncanny bassist of RoaRomin.
He plays a Zombie deck related to Burn Damage and telling ghost stories.
- Blinding Bangs: His bangs cover his eyes at all times, highlighting his uncanny character.
- Casting a Shadow: His Zombie Monsters are DARK.
- Catchphrase: "Omaeno Ushirou da!". It's just him repeating his name out of fear that everyone will forget it, but the characters constantly mistake the words for "Omae no ushiro da!" (Japanese for "Behind you!").
- Dark Is Not Evil: Despite working for Roa, he's not such a bad guy himself, although he is creepy and scary.
- Dub Name Change: To Toombs in the English version of Yu-Gi-Oh! Rush Duel: Dawn of the Battle Royal.
- Foil: When compared to Getta. While Ushiro is Dark Is Not Evil whose creepy behavior tends to stem from how he's constantly ignored, and playing a somewhat fair game against Luke, since while Luke was creeped out by him, it didn't really impact Ushiro's hand destruction tactics. Getta on the other hand, looks comparatively normal, and from what has been seen, quite enjoys being a jerk while giving his bandmates an unfair advantage.
- Forgettable Character: No one outside of Roa Romin is able to remember his name, not even Yuga.
- Gameplay and Story Integration: It's unclear how deliberate this is, but only one of his cards has been released in Yu-Gi-Oh! Rush Duel, as opposed to almost every other character who have most of their decks in the game, paralleling how he is often forgotten within the series.
- Ghost Story: His deck revolves around Japanese Ghost Stories, which he tells as he summons his monsters.
- Glass Cannon: All his monsters have low ATK, and his deck relies on burn damage.
- Look Behind You: He accidentally does this all the time, as he exclaims his Punny Name whenever someone addresses him as "him" or "you" instead of calling him by his name. Luke eventually catches on to the fact that his opponent's catchphrase was actually his full name.
- Nobody Loves the Bassist: He is distraught because nobody remembers his name, and Luke promising to do so after their duel is something he appreciates. He and Getta are the least popular members of the band, which bothers him unlike Getta who doesn't seem to care.
- Our Zombies Are Different: His monsters are based on Japanese ghosts, except for Wicked Shadow - Dark Rooker, who instead looks like a typical Grim Reaper.
- Punny Name: Read in Eastern order (Omaeno Ushiro), his name is homophonous to "behind you".
- The Runt at the End: Or rather the first, as he is the only member of RoaRomin to not have a deck based on music.
- Screw This, I'm Outta Here!: Disgruntled with Roa's selfishness during the Team Battle Royal, he and Getta abandon him and the tournament.

The drummer of RoaRomin, he notably has a big appetite. Getta plays a Thunderbeat Deck based on Drums and Thunder Beetles. He leaves RoaRomin and becomes an employee of Neiru.
- Affectionate Nickname: Roa addresses him with the "-chan" honorific.
- Ambiguous Situation: He let himself fall into Neiru's trapdoor while swearing revenge against Roa, but is later seen hanging out with Ushiro in the Seven Hells Hall with no answer as to whether they'd reconciled.
- Big Eater: Ate every snack and bento-lunch backstage with no trouble at all.
- Chekhov's Skill: His hacking, which he used to conceal information about Sevens Road Magician, later becomes the reason Neiru accepts him as a servant, and comes in handy when uncovering the identity of the person behind the Goha Rush Duel Team Battle Royal.
- Childhood Friend: He and Roa have known each other since they were little.
- The Cracker: Revealed to have hacked Goha to make Sevens Road Magician appear to be illegal. He's such a good hacker that Neiru is impressed with his skills.
- The Dragon: To Roa, though he doesn't duel, being instrumental in his manipulations against Romin and hacking Goha to make Sevens look illegal.
- Dude, Where's My Respect?: His beef with Roa, for leaving him as a side character, always shrugging off his feelings, and not even letting him duel in the gauntlet. Yuga and co. admit that he had a lot of patience for putting up with it as long as he did. It's so bad that when Yuga and co. meet up with him again, they initially think he's Ushiro.
- Elvis Impersonator: Dresses like one while working for Neiru Saionji, even wearing a blond pompadour wig.
- FaceHeel Turn: Although he is still against Yuga and co., he goes from working for Roa to Neiru, due to his anger at Roa, since Roa has more or less undergone a HeelFace Turn to more of a rival.
- Fat Bastard: On Roa's orders, he devours all of the snacks and provisions backstage so as to trigger Romin's hunger-driven berserk state, and is noted to have a fair amount of gut.
- Foil: When compared to Ushiro. While Getta looks fairly normal, he's actually a Big Eater Jerkass while Ushiro looks creepy, but ultimately proves to not be that bad a person.
- Forgettable Character: Since Yuga and co. didn't duel him, they fail to recognize him in the Garden of Providence, thinking he must be Ushiro at first until Romin corrects them. Later he isn't forgotten, but then Ushiro is forgotten by even Yuga.
- Jerkass: Had no qualms about hogging all the food for himself on Roa's orders.
- Redemption Rejection: Well, for a definition of redemption; after losing to Roa, he almost reconciles with him, only for Luke to blurt out about the drumming robot and lets himself drop into the Pit Trap, swearing revenge.
- Screw This, I'm Outta Here!: Disgruntled with Roa's selfishness during the Team Battle Royal, he and Ushiro abandon him and the tournament.
- Shock and Awe: Plays a deck of Thunder Monsters.
- Thunder Beetle: The Thunderbeat monsters are based on beetles and drums.
- Took a Level in Kindness: After reconciling with Roa, he becomes much nicer, even helping out Yuga and Co on occassion.
- The Unfavorite: Among the fans, he and Ushiro aren't popular, and he gets no focus in the band. He doesn't appear to be bothered by this at first, but it ultimately leads him to abandon Roa to work for someone who respects him - Neiru Saionji.
- The Unfought: He was the only member of RoaRomin not to participate in the battle against Yuga and his friends in the first arc. This is part of what leads him to betray Roa and take him on himself.
- Weak, but Skilled: Averted with the Thunderbeat monsters themselves which are low-level normal monsters with unimpressive ATK and DEF values. However, having them on the field enable the use of spell/trap cards with a variety of effects like powerful burn damage, monster destruction, and life point regeneration to hold the field.

One of Yuga's many "roads", modified from a Goha Corp Drone.
As a member of Goha 66 he plays a LIGHT Machine deck based on the Corporate lifestyle. In Yu-Gi-Oh! SEVENS Luke! Explosive Supremacy Legend!! manga, he plays a Drone-based Machine Deck instead, using several cards based on his likeness.
- Abhorrent Admirer: His appreciation of Nico's appearance and suggestion that Romin try out the look herself gets him this reaction from the two girls. He does this again in the Beach Episode when Yujin comes to Goha 7th Elementary and gets thwacked aside for his trouble.
- Aesop Amnesia: Played for drama. The fragment of Kaizo in the seat of the Duel Bicycle ultimately became True Companions with Yuga and co. and sacrificed himself so that Yuga could create Magnum Over Road, albeit with the knowledge that Yuga would get the rest of his data back if he defeated Neiru. Consequently the rest of Kaizo did not go through these experiences and is all too happy to betray them by siding with Goha 66.
- Ambiguous Situation:
- Was shown to go unusually quiet after defeating Goha's drones, though he seemingly returns to normal without much issue. It later turned out he was infected with a virus and moved what was left of his code into a transforming bike/duel robot attachment Yuga made him.
- His level of knowledge about his time as a bike seat. His rivalry with Sebastian is based on knowing this, but when told about it in the meeting between Goha 7th and 6th he reacts as though he's heard it for the first time. It's possible Yuga wiped his memory of the event, but hasn't been clarified.
- Butt-Monkey: He tends to get the tedious tasks heaped on him, and Yuga casually calls him failed due to his adoration of Romin.
- Cast From Hitpoints: His traps rely on using his life points as currency to debilitate his opponent's monsters.
- Computers Are Fast: Is shown to finish his turn within seconds while dueling against Goha drones. And allows him and Sebastian to communicate a plan in .05 seconds so Kaizo can escape and warn Neiru.
- Corrupt Corporate Executive: His ace, Shining Black Corporate King Arktalk the Corrupt.
- Crouching Moron, Hidden Badass: Despite his ridiculous behavior and quirks, he can Duel, and is capable of beating three Goha Drones in a duel so high-speed their cards can only be seen in a Freeze-Frame Bonus. He is also the best duelist of Goha 66, almost beating Luke as opposed to getting beaten offscreen en-mass.
- Demonic Possession: Of sorts. He got infected with a computer virus while dueling three other Goha-bots, implanting a false AI into his main body and leaving the remnants of his coding in a hardware upgrade Yuga created to make it easier for him to move about in.
- Do-Anything Robot: Not at first, but once Yuga got his hands on him, Kaizo has received many reprograms and modifications to handle a variety of tasks, whether it be to record, guide people through Duels, or even do paperwork. It ultimately comes in handy when Kaizo gets infected by a computer virus that assimilates most of his coding, as it ensures that he's not totally gone, with a heavily damaged backup copy in one of said modifications (A bike-like object that also transforms to let Kaizo duel).
- FaceHeel Turn: Abandons Yuga and Co for Goha 66 due to his constant mistreatment. He eventually switches back, but it's implied he's still keen for revenge, though he toes the line for now.
- Fanboy: Of Romin, to the point of cheering her on over Yuga. Which is probably what prompts Yuga to reset and reprogram him at the end. Despite this, he continues to focus his attention on her much to her annoyance, though she uses this to her advantage during certain episodes to get him to comply.
- HeelFace Turn: Though never a villain per se, after modifying Kaizo he becomes a member of the group who helps out at every turn.
- Hypocrite: He calls out Sebastian for cozying up to Asana because of her power, despite his tendency to side with Romin over Yuga (though it's unclear if Sebastian knows this).
- Of course, Kaizo doesnt exactly like Romin because of her power, so he might just be angry that Sebastian is doing it to Asana for the wrong reasons.
- Meaningful Name: Its name is derived from the Japanese word for "remodel", 改造 (kaizō), which is appropriate given it was modified from a Goha Corp Drone, and continues to get modified whenever Yuga needs to perform some repetitive task. It's Lampshaded in the episode when he gets his name as being too literal. It also made the three Goha drones he dueled even more suspicious of him.
- Mythology Gag: Kaizo leaving Yuga and co to become a prominent member of a Mega-Corp, along with his plans to create more like him, is a Lighter and Softer version of Ais path after leaving Playmakers faction.
- Put on a Bus: He disappears every few arcs, being captured by Neiru in the Maximum arc and leaving Yuga in the Team Battle Royal arc after getting fed up with his treatment. He lampshades it in the Goha 6 Siblings arc after getting trapped in Yuo's iron maiden and blasted into space.
- Reforged into a Minion: Was originally a Goha Corp drone, but was later modified by Yuga to respond to him. He also gave it more personality, though it wasn't the nicest to him in episode 3, consistently favouring Romin over Yuga and insulting him, which drives him to start rewiring Kaizo at the end of the episode 4, though Kaizo still ultimately favors Romin.
- Salaryman: His theme as a member of Goha 66 including a suit wearing robot body.
- Transforming Mecha: Yuga modifies his Duel-Bicycle to add a robot form that Kaizo can duel in, though it has the detriment of burning through the energy capacity. It ends up saving Kaizo from a computer program that invades his main body, as his AI is able to preserve itself in said bicycle, though heavily damaged in the process.
- Turned Against Their Masters: Is prone to going against what Yuga desires in favor of following Romin blindly, though the latter manipulates Kaizo into doing the group's plan anyways.
- Undying Loyalty: Not to Yuga, but to Romin. When the prospect of her being a spy comes up, he immediately switches sides to stay with her. It's Played for Laughs.
Princess G/Gibumi Purisaki

A performer and singer that Romin looks up to, and the same person who gifted her Prima Guitarna. She initially works for Goha Music, but after refusing to support their attempts to quash Rush Duels, is fired and strikes it out on her own. Like Romin, she also uses a Psychic Deck, spearheaded by the Omega Psychic-Type Fusion Monster Omega Guitarna the Supreme Shining Superstar.
- Bare Your Midriff: Her outfit exposes her stomach area.
- Biker Babe: Shown to ride a motorcycle after Goha fires her for admitting she likes Rush Duels.

- Nerd Glasses: In her disguise, her glasses look like Carly's.

- Obfuscating Stupidity: In her Sensei-chan persona, she is a Cute Clumsy Girl. This is lampshaded when she crashes into Mimi, who tells her to drop the act.
- The Rock Star: A professional one, though her persona is that of a Cool Big Sis and Biker Babe.
- Sensei-chan: Infiltrates Goha 7th this way after she is fired by Goha Music in order to encourage Romin's love of Rush Duels.

A girl who is dressed like a clay figure and apparently comes from an ancient civilization. She first appears to announce that Goha will hold a Rush Duel tournament.
She uses an EARTH Pyro deck based on sweets and dogu that focusses on milling her deck to summon and empower her monsters.
- Ambiguous Situation: The trend of "is she Sorako?" continues, with Umiko appearing right after she disappears, leaving it even more confusing.
- But Now I Must Go: Like Sorako and Chikako before her, after her duel she has to leave, claiming she is going back to the past.
- Dishing Out Dirt: Her EARTH deck are based on dogu creatures though still Pyro-type.
- Dude Magnet: Charms Menzaburo due to his love of Sorako, and at the end of their duel Nick gets a crush on her too.
- Identical Stranger: At first, Romin and Kaizo mistake her for Sorako and Chikako, respectively. Menzaburo also thought she was Sorako who came back to Earth.
- Punny Name: Her name sounds similar to the word "Kako", which means past, fitting with her claims of being from an ancient civilization.
- Suspiciously Specific Denial: She denies to Menzaburo that she is Sorako and states she doesn't know anything about her or Chikako even through he only mentioned the former and in theory shouldn't even know anything about the latter.
- Sweet Baker: Zigzagged, since Kakoko is an antagonist who creates a delicious Stonehenge of Sweets, but lacks the Cute and Psycho behavior of Chikako, acting more like Sorako.
- Verbal Tic: She tends to end her sentences with "Kako".

A girl who is dressed like a fish, presumably a Merperson of some sort. She takes over as announcer of the Rush Duel tournament once Kakoko Sweets left to go back to her era. Umiko plays a WATER Thunder Deck that utilizes Umi and Effect damage.
- All There in the Manual: The official website revealed that her outfit is based on a footballfish specifically.
- Ambition Is Evil: Wants to take over Goha, but doesn't know how.
- Electric Jellyfish: The basis of her deck, though it also includes Electric Octopi.
- Identical Stranger: She is the third girl who resembles Sorako and appeared right after Kakoko "returned" to her era.
- Jerkass: Is rude and lazy while doing her job, even when acting like a Genki Girl like her predecessors.
- Lazy Bum: She hates her job at Goha, and is incredibly lazy, often not even reading her cards entirely, which makes Gakuto want to set her straight.
- Mobile Fishbowl: She wears a fish-themed diving helmet filled with water, but is still able to talk normally.
- Nice Character, Mean Actor: When working as an announcer for the Rush Duel tournament shes as energetic and friendly as her lookalikes, but when Gakuto meets her shes a foul mouthed slob who couldnt care less about doing her job properly.
- The Runt at the End: Unlike her counterparts, Umiko is a lazy jerkass, isn't capable of retracting into her suit or flying like the others, and doesn't use a Pyro type deck. She also parts with Gakuto on bad terms unlike the past two.
- Shock and Awe: Thunder effect damage.
- Tentacled Terror: Downplayed since she is a jerkass, but her monsters Zapzap Octospark and Showering Infernofish are octopi, with Infernofish being an Octopi mermaid.
- Verbal Tic: Blub, since she is a fish.

- Awesome Anachronistic Apparel: Dresses like a Victorian Gentleman with a cane and monocle.
- Birds of a Feather: He and Yuga share the same passion for engineering, and Yuga even goes along with his metaphors and exultations of gears.
- Boring, but Practical: In comparison to the construction company ran by Asana's grandfather in the past, Akinori's business can be seen as this. As strange as gears seem, they are an integral, basic, part of many machines, meaning that even with new companies such as Goha Corp, Kamijou Gear Company can maintain itself as Old Money as they are extremely broad and flexible in what machines they produce.
- Cloud Cuckoolander: Due to being obsessed with gears, with Tiger having to shout at him to stay on track.
- Cool Old Guy: A bit gear obsessed, with his grandchildren finding him annoying, but Yuga finds him cool.

An AI created from Luke's manga that seeks to become one with him in order to recreate the story's events in real life.
He duels with Luke's deck, which he enhanced with "The☆" and the Fusion card in order to create powerful High-Dragon Types through Fusion Summon.
- The Ace: Even more so than Luke, having a powered-up version of his deck thanks to Fusion. He is introduced defeating Yuo, the mastermind of the arc who had just finished crushing Yuga, and then wins against Tiger, the one opponent Luke feared and didn't believe he could beat. Ironically, unlike Luke, he has lost to Yuga, albeit only through almost impossible odds.
- Ace Custom: The☆Lukeman's Fusion card lacks the purple swirl the Fusion cards, Yuo and Yuga use, but this becomes a subversion once the Fusion card he uses becomes more common due to him leaving many others throughout the city after leaving the planet.
- Art Initiates Life: Created from Lukes childish manga being faxed improperly by Tiger.
- But Now I Must Go: Flies into space to seek new adventures.
- Contrasting Sequel Antagonist: To Yu-Gi-Oh! VRAINS Ai. Both are A.I. based on one of the main characters, share a dark color scheme, are capable of creating new cards, often act over the top in their duels, and are the Final Boss in their respective arcs. While they both serve as antagonists, Ai started as an ally to Yusaku, but pulls a FaceHeel Turn out of guilt for being the Sole Survivor of the Ignis and learning Yusaku dies in the future trying to protect him, pulling a Xanatos Gambit to prevent that, while The☆Lukeman comes into conflict with Yugas group out of a misguided desire to live out the manga Luke drew but comes to respect Yuga after their duel and parts with him on good terms. Both are also incredibly loyal to their origins and desire to be one with them, but whereas Ai tried convincing Yusaku to fuse with him, The☆Lukeman forcibly takes over Lukes body and mind without consent.
- Does Not Know His Own Strength: He ends up crushing Yuga's hands accidentally after shaking his hand for the good duel.
- Dragon-in-Chief: He technically works under Yuo whom he defeated in a duel.
- Expy: While he is an Affectionate Parody of Tokusatsu in general, the one he has the most in common with are the heroes from the Ultra Series. Following the original Ultraman's story of a being from space who bonds with a human to fight against evil together. Not to mention his "The☆" motifs resembling those of the franchise's first anime, The☆Ultraman.

- The Magic Poker Equation: In all three of his Duels so far he draws the same combo needed to Fusion Summon Superstrike Dragon Dragiastar F.
- The Man Behind the Man: Created the Fusion card that Yuo used to defeat Yuga, although he isn't responsible for Yuo's plans.
- Third-Person Person: Uses this in place of pronouns.
- Unwitting Instigator of Doom: Downplayed, the Goha siblings were approaching before his creation. Still, him creating Fusion gave Yuo his most powerful weapon and allows him to start his own plan. Interestingly, it combines this with Spanner in the Works, since he then also defeats Yuo, forces him to try and recruit him as an ally, and ultimately wrecks his plan completely.
- Walking Spoiler: The☆Lukeman's existence is a major twist in the Goha Siblings arc since his appearance completely derails it. And the fact he is a character of his own and not just Luke being influenced by a Goha drone reveals the major twist of the penultimate episode of the arc.
