    Sekai Kamiki 
https://static.tvtropes.org/pmwiki/pub/images/sekai_7512.png

Voiced by: Kazumi Togashi (Japanese), Shiona Carson (English)
Main Gunpla: BG-011B Build Burning Gundam, Musha Godmaru, TBG-011B Try Burning Gundam, KMK-B01 Kamiki Burning Gundam

A second-year who transferred to Seiho Academy, and student of the Jigen Haoh school of martial arts. Sekai dreams of being a master martial artist, and joins Fumina's team after realizing Gunpla Battle will allow him to sharpen his skills.


  • Audience Surrogate: He'd never even heard of Gunpla Battle before meeting Fumina. As such, he has limited knowledge of the world of Gunpla, making him ideal to spew Exposition at.
  • Bare-Fisted Monk: Having trained in hand-to-hand martial arts, he uses a Gunpla that focuses on fighting with no weapons other than its fists.
  • Barehanded Blade Block: He uses a Dom to block the Enact's blade. Interestingly, though, he doesn't use two flat hands to catch it, but a flat hand and a fist.
  • Bequeathed Power: His Build Burning Gundam was made by Sei Iori, protagonist of the previous Build Fighters series, who retired for a year to spend time with his girlfriend in Europe.
  • Big Eater: He at least doesn't think he'll have trouble eating two bento in Episode 3.
  • Born Lucky: His male classmates sure think so, for being able to have lunch with Fumina (who is an upperclassman, no less) and having Mirai as a sister. And, you know, picking Build Burning out of a lot of possible Gunpla in the clubroom.
  • Calling Your Attacks: Sekai shouts all his attacks as he performs them.
    Sekai: Jigen Haoh school! Seiken-Zuki!
  • The Chosen One: When Mr. Ral sees Sekai in action and how he's amazing despite being an absolute beginner, he proclaims that he's "the Second Coming of Reiji."
  • Clueless Chick-Magnet: Has beautiful girls throwing themselves at him without even trying... but he has no idea what a date is.
  • Contrasting Sequel Main Character: Far more Hot-Blooded than Sei and Reiji combined.
  • Dangerous Forbidden Technique: Using Build Burning's Super Mode actually makes Sekai feel the damage the Gunpla takes, in a phenomenon called "assimilation".
  • Exactly What It Says on the Tin: When Build Burning Gundam uses its Super Mode, a halo of flames forms around it.
  • Expy: Shares a lot of traits with Domon Kasshu, the Hot-Blooded Warrior Therapist martial artist who served as Mobile Fighter G Gundam's protagonist. Makes sense, considering his master IS this world's iteration of Domon.
  • The Hero: The pilot of the show is essentially about him for being the main fighter in the team.
  • Heroes Fight Barehanded: See Bare-Fisted Monk.
  • Heroes Prefer Swords: He uses a Flaming Sword in the Final Battle. His Kamiki Burning Gundam has a physical sword.
  • Hot-Blooded: Sekai's method of Gunpla battling. He uses nothing but flame covered punches and kicks in a match. Build Burning is even described as " A hotblooded Gunpla emitting flames from its body!" in official materials.
  • I Am Your Opponent: Saving Fumina's Powered GM Cardigan from Daiki's Enact, he tells Daiki this.
  • I Just Want to Be Badass: He states that he learned martial arts to be strong. Time will tell if there's any other reason for this. Expanded to wanting to be more immersed in the world of Gunpla, regretting that he had not found out about it much sooner.
  • Idiot Hero:
    • Forgot the address to the school he was supposed to be enrolling in, forcing him to wander the streets asking people if they'd seen his sister.
    • Has a meltdown in episode 2 when he realizes he's forgotten his lunch.
    • His sister Mirai even describes him as "crude, careless, simple-minded, hot-headed, gluttonous and disorganized".
  • Instant Expert: He's able to make top-level repairs to his Gunpla after simply being shown how by Shia. Though to be fair, Shia's an incredibly talented engineer from the Gunpla Academy, so it might not be such a shock that he learned so fast...
  • Invincible Hero: Just like Reiji before him, after suffering a few crushing losses before the tournament, he and his team start winning non-stop. It doesn't come without some serious pain, however.
  • Leeroy Jenkins: He rushes out ahead in the episode 3 practice match, blocking Yuuma's view and getting caught in a sneak attack by Team Song Dynasty Vase right after.
  • Logical Weakness: He doesn't have any prior experience with Gunpla Battles and is just using Build Burning to replicate his fighting style.
    • In Episode 4-5, this means that when faced with a completely different environment than on the ground (like the sea or space), he more or less just hopelessly flails about. Sekai eventually corrects this through additional training.
    • Episode 12 shows something more - Sekai's so focused on his martial arts, he has no defense against exotic techniques like Adou's combining Attack Drones or giant Devil Gundam hands that can eat anything they get their jaws on.
  • The McCoy: He is the more emotional member of the group.
  • Next Tier Power-Up:
    • In episode 5, he develops new martial arts techniques specifically for Build Burning Gundam, like being able to infinitely Double Jump through space.
    • In episode 13, he creats a particle manipulation attack that can destroy the moon in a single hit.
    • In episode 14, his Build Burning is upgraded to Try Burning by Yuuma to withstand the strain of this new technique.
    • In episode 20, he starts using Mobile Fighter G Gundam techniques like Bushin Sapou God Shadow and Erupting God Finger.
  • New Transfer Student: In the sense that he should have been at the school a month prior, but decided to go training with his master instead. Played straight when he finally does show up for class — and gets seated next to Yuuma, no less.
  • Nice Guy: A normally friendly guy. He's just a little bit excitable.
  • Oblivious to Love:
  • Person of Mass Destruction: By episode 13, Sekai and Build Burning are capable of blowing up the moon with a single attack.
  • The Rival: After his battle with Kijima, He flat out declares it. A sentiment Kijima returns.
  • Screw This, I'm Outta Here: His reaction upon realizing that Gunpla Battle is actually a bunch of models rather than actual physical martial arts. He quickly grew to like it though.
  • Shed Armor, Gain Speed: In a roundabout way: Try Burning sheds large portions of its armor when entering Super Mode, to stop all the particles it generates to boost its power and speed from getting trapped inside the Gunpla and exploding.
  • Shoryuken: Soten Guren-Ken is an upper cut.
  • Spirited Competitor: In his class introduction in Episode 2, he actively welcomed any challenges. Further putting him square into this tropes is his desire to fight against the best the world has to offer. Now that he's in the National Tournament, he'll likely get his wish and then some.
  • Squee: His reaction upon witnessing the Tryon 3's debut in the Nationals. In complete contrast to the entire audience.
  • Super Mode: Build Burning Gundam can temporarily channel all the Plavsky particles around it to boost its speed and offensive power, combining the super modes of Star Build Strike and God/Burning Gundam into a single suit.
  • Super Prototype: Build Burning Gundam was built by Sei for the 11th World Championship; Yuuma states it's been upgraded since then.
  • Super Robot: Because Sekai's Build Burning Gundam was based after Domon Kashuu's God/Burning Gundam, that it was bound to have Super Robot qualities, from its emphasis on close-quarters martial-arts, to its ability to defy the laws of physics, thus making it Team Try Fighers' ace unit.
  • To Be a Master: Joins Team Try Fighters to help him become a master martial artist. Then wants to learn more about Gunpla. And then he ends up training in his martial arts with Gunpla.
  • Took a Level in Badass: Learning from Shia about building and repairing Gunpla allowed him to go from being effortlessly curb stomped by Adou to matching blows with Wilfred, Adou's equal.
  • Vitriolic Best Buds: If it doesn't come off as Ho Yay, his relationship with Yuuma is most certainly shaping up to be this.

    Fumina Hoshino 
https://static.tvtropes.org/pmwiki/pub/images/fumina_9623.png

Voiced by: Yui Makino (Japanese), Elizabeth Loennborn (English)
Main Gunpla: RGM-237C Powered GM Cardigan, SD-237 Winning Gundam, SD-237S Star Winning Gundam

A third-year at Seiho Academy and president of the school's Gunpla club. Fumina dreams of winning the All-Japan Gunpla Battle Championships. This leads to her recruiting Sekai and Yuuma into Team "Try Fighters", so she can compete in the tournament's 3-vs-3 battles.

Though she is not aware of it, Lady Kawaguchi considers her to potentially be her successor, and pits her against Shia Kijima, her other candidate.


  • Absurdly Sharp Blade: Her Star Winning has a number of physical and energy based particle manipulation sabers that can cut beam attacks in half.
  • Ace Custom: The standard Powered GM was a GM customized to be a testbed unit for various next-gen mobile suit parts. Fumina then takes that basic testbed unit, and turns it into the Powered GM Cardigan: a Walking Armory with enough thrust to turn and burn.
  • Attack Drone: Star Winning adds a number of different types of funnels.
    • Guard Bits which can act either as beam shields of as remote beam blades. Can also combine to form her "Starcross" beam shuriken.
    • Gun Bits, a pair of remote beam cannons.
  • Audience Surrogate: The other half of this trope. While Sekai is the one who asks things the audience would say, Fumina represents the fans of the first season, or Gundam in general, who could only dream of playing Gunpla Battle.
  • Badass Adorable:
    • Winning Gundam, which is Super-Deformed, but also deadly in a fight.
    • The trope also fits Fumina herself, especially since she's noted in-universe to be a cutie.
  • BFS: The Star Winning Gundam has the Mega Blade. Normally a solid blade mounted under its rifle, it can extend itself into a beam sword that's big enough to cut through mobile armors.
  • Childhood Friends: With Yuuma. Totally glossed over by the series, barring the promise both of them made while kids to go to the national championships together.
  • Clingy Jealous Girl: After Sekai mistakenly introduces himself as her boyfriend in episode 10, she seems to get annoyed whenever other girls, like Shia and Gyanko, flirt with Sekai.
  • Combining Mecha: One of Winning Gundam's gimmicks is that it combines with other mobile suits.
    • Power Fist: The Winning Gundam's torso transforms into the Winning Knuckle, a giant robotic fist and latches onto the Build Burning Gundams' hands.
    • BFG: Another part of it combines with the Lightning Gundam's rifle to become the Winning Launcher.
  • Crippling Overspecialization: After a 1-on-1 battle against Lady Kawaguchi, it becomes clear that, with Hoshino having put so much focus into supporting Sekai and Yuuma, the Winning Gundam does rather poorly on its own. This ultimately leads to her building the Star Winning Gundam, with which she addressed this weakness and created a Gunpla that is more than capable of fighting on its own, while still able to support her teammates like she originally intended.
  • Determinator: In Episode 2, despite being caught by Miyaga's Agrissa, she refused to give up even as her Gunpla began to crack from the strain.
  • Fashionable Asymmetry: Her shorts have a large black band on her left leg, but not on her right.
  • Faux Action Girl: Fumina actually starts as this - while she's a capable Battler, she puts too much focus on support and thus is pretty much useless. Her match with Lady Kawaguchi helps her get out of this trope.
  • The Glomp: Gives both Yuuma and Sekai giant hug after years of trying, she finally gets past the first round of the prelims.
  • Hero Worship: She worships a female gunpla fighter that utterly wiped the floor with her opponents in a world championship.
  • Hot-Blooded: Not exactly apparent outside of Gunpla battles, but by the time she get her Star Winning Gundam to use its Winning Beam, she just cranks up the screaming.
    Full... POOOOOOWWEEERRRRRRRRRR!!!!!
  • I Just Want to Be Badass: The reason why she started battling was because she wanted to be a winner, even amongst the boys.
  • Jack of All Stats: Because her SD Winning Gundam was built for a support role and was the most balanced of the Team Try Fighters' gunpla, it was neither going to defy the laws of physics as well as the Build Burning Gundam nor abide to the laws of physics as well as the Lightning Gundam.
  • The Kirk: She tries to balance Yuuma and Sekai's continuous fighting.
  • The Leader: She's the leader of team Try Fighters and has the most experience with Gunpla battles in the team.
  • Leave The Two Love Birds Alone: Played for Laughs in episode 8, when she, along with Yuuma and Mr. Ral, left Sekai to "comfort" Gyanko. Justified since Fumina once faced the team Gyanko would eventually face in the semifinals, and she rather cares a bit for Gyanko as well...
  • Logical Weakness: While Winning Gundam's small size makes it very difficult to hit, if an opponent manages to grab onto it, there's very little that it can do.
  • Mix-and-Match Weapon: Her Star Winning uses a beam rifle with a fold out sword. Even before that, her Winning Gundam's rifle can project a beam saber from its barrel, similar to how Zeta Gundam. Additionally, it could combine with the Winning's V-fin to form a crossbow.
  • Modesty Shorts: Fumina can always be seen with a pair of bike shorts on, even while wearing her school uniform. Though considering how tight they are... hmmm. And the Super Fumina has these as well (because of course Minato would be that desperate to replicate the girl he worships so much)
  • Ms. Fanservice: Besides her school uniform, Fumina wears almost nothing but several sets of skintight sports-bras and matching bike shorts (with a yellow sweatshirt for just a bit of casual modesty... sometimes).
  • Next Tier Power-Up:
    • Switches from her customized GM to the built from scratch Winning Gundam in episode 5.
    • Further upgrades Winning Gundam into Star Winning in episode 14.
  • Nice Girl: Much like Sekai, she's a kind schoolgirl who just happens to have a passion... in her case for Gunpla.
  • Passionate Sports Girl: She loves Gunpla Battle. Her casual outfits show that she has a rather fit body, implying that Fumina likes sports in general (but Gunpla Battle, being the Serious Business it is, stands first far-and-away).
  • He Is Not My Boyfriend: She says this in Episode 10 when her mom asks about Sekai.
  • Sensual Spandex: Her casual outfits are nothing but this, in a pretty blatant example of Fanservice.
  • Ship Tease: With Sekai, natch. Her Clingy Jealous Girl behavior implies she probably has a crush on him.
  • Spanner in the Works: She ends up derailing Team SRSC's plans by introducing the Winning Gundam instead of using Powered GM Cardigan.
  • Stripperiffic: With her casual attire consisting of skin-tight bike shorts and a sports bra (and little else aside from a yellow sweatshirt), Fumina frequently bares her midriff and legs. Even on the occasions she does wear her sweatshirt, she wears it unzipped.
  • Super-Deformed: Fumina's Winning Gundam is a half sized Gunpla with a giant head and tiny body.
  • Super Mode: Her Star Winning Gundam's real sized Real Mode.
  • Swiss-Army Appendage: Two of Star Winning's Attack Drones functions not only as legs for the Real Mode, but also as BFGs, as properly demonstrated when she used it to eliminate one of Team Titan's fighters in episode 19.
  • Team Mom: She's the one who keeps the team working together. This is also reflected in her Winning Gundam, as Minato notes, which was made to ensure that Sekai and Yuuma worked together.
  • To Be a Master: Ends up forming Team Try Fighters to be a Gunpla Battle champion.
  • Tomboyish Ponytail: Fumina wears her hair in a ponytail, reflecting her athletic interests.
  • The Rival:
    • She and Gyanko are quickly revealed to not like each other all that much, arguing over who's the better Gunpla Battler and who Sekai should be spending his time with.
    • Come the National Tournament, Lady Kawaguchi sees her as one to Shia Kijima, of which Fumina gladly accepts.
  • Transforming Mecha: Her Star Winning Gundam can switch between a Super-Deformed and a standard-sized mode.
  • Walking Armory:
    • The Powered GM Cardigan has an impressive tally of mounted weapons. So far it's been shown to have a beam rifle, balloon launchers, missile launchers, gatling gun, two beam sabers and two beam cannons.
    • Winning Gundam has missile launchers, vulcans, a beam rifle, a beam crossbow, and can use the Winning Launcher. That said, it's also deconstructed somewhat: carrying many weapons means that Fumina hasn't mastered any of her weapons.
  • Wave-Motion Gun: Her Star Winning Gundam's "Winning Beam".

    Yuuma Kousaka 
https://static.tvtropes.org/pmwiki/pub/images/yuuma_2645.png

Voiced by: Yūma Uchida (Japanese), Mitchell Wallace (English)
Main Gunpla: LGZ-91 Lightning Gundam, GW-9800 Gundam Airmaster, KUMA-02/F Bearguy F (Family), LGZ-91-Fb Lightning Gundam Full Vernian, TBG-011B Try Burning Gundam, MSZ-006LGT Lightning Zeta Gundam, Gundam Lightning Black Warrior

A second-year model builder at Seiho Academy, and younger brother of China Kousaka. Yuuma dreams of being a master model builder, and joins Fumina's team to broaden his horizons.


  • Ascended Extra: Yuuma Kousaka went from being briefly mentioned as China Kousaka's younger brother in Build Fighters to being one of the three main characters in Try.
  • Boring, but Practical: Unlike the Winning or Build Burning, Yuuma's Lightning Gundam doesn't rely on any particular gimmicks besides a transformable backpack. It just flies very fast and shoots very far, and its basic performance already outstrips most every other Gunpla it fights.
  • Broken Pedestal: He's actually this for Minato Sakai, his biggest rival, who used to admire Yuuma until he quit Gunpla Battle.
  • Chekhov's Skill: Like the Re-GZ that it's based off of, the Lightning Gundam doesn't have a transforming fighter mobile armor mode. Rather, it has a customized version of the Re-GZ's Back Weapon System flight unit that attaches itself to the Lightning Gundam to turn it into a high-speed fighter. In their battle against the G-Masters, he takes control of the Back Weapon System to return to the fight after he sacrifices the Lightning Gundam to cripple Shunsuke's Mega-Shiki.
  • Chick Magnet: Yuuma is fairly popular with the girls of their school. His looks were complimented many times in Episode 3
  • Childhood Friends: With Fumina. Totally glossed over by the series, barring the promise both of them made while kids to go to the championships together.
  • Cold Sniper: He just shows up, silently starts sniping, and manages to land more hits than misses on Sekai's Dom, and is even leading his target and anticipating where Sekai will dodge. He also abstains from the Trash Talk other Battlers regularly engage in. However, he's more than willing to talk trash towards Sekai, especially for any screwups he commits to. The pre-fight and post-fight banter they get into in Episode 3 speaks volumes on its own.
  • Combat Pragmatist: In his first appearance, he opens up with a surprise attack, and then keeps shooting instead of trash-talking.
  • Death Glare: Played for Laughs. Yuuma gives one to Fumina when he offers to help teach Mirai about Gunpla for her Gun Colle event and she volunteers to help too.
  • Did I Just Say That Outloud: Has a tendency to do this whenever he starts thinking about his plans to be alone with Mirai.
  • Disqualification-Induced Victory: Winning the Meijin Cup at the very end of the series. Minato certainly would have won had he'd just ask Fumina for permission over the Super Fumina.
  • Distracted by the Sexy: When Mirai shows up, he's instantly charmed by her, and when she asks him if he is going to join the Gunpla battle team, he ends up saying yes, prompting Sekai and Fumina to drag him into the club. This is also the reason why he joins Fumina in picking up Sekai. The redhead is quick to call him out on this.
  • Dogged Nice Guy: Towards Mirai, not that you can blame him.
  • Embarrassing Nickname: He seems embarrassed that Fumina still calls him "Yuu-kun", the nickname she gave him when they were kids; Yuuma himself has stopped using her old nickname "Fumi-chan" in favor of "Hoshino-sempai".
  • Everyone Can See It: He's not exactly subtle in regards to his crush on Mirai. Even Sekai had noticed it, which is really saying something.
  • Famed In-Story: Yuuma is pretty well-known amongst fellow gunpla modelers and battlers as the winner of the Artistic Gunpla Gran Prix.
  • Heel–Face Turn: Betrays Daiki and helps out Fumina at the end of episode 2's battle. Actually joining the team, however, involved something else.
  • Heroic BSoD: Went into a depression and quit Gunpla battle after losing to a jerkass fighter 2 years ago. He almost quits again when that same fighter, Adou Saga, beats him at the training camp in episode 11.
  • Hyper-Competent Sidekick: To Daiki. Daiki's Enact is nothing more than a custom paintjob suit with little modding. Yuuma's Lightning Gundam is designed with combat in mind, and significantly more durable. He's also a better fighter than Daiki.
  • The Lancer: Serves this role compared to Sekai and Fumina, being much more level-headed.
  • Lightning Bruiser: He eventually upgrades to this, as the Lightning Gundam Full Vernian. Which can keep up with a Kyrios in Trans-Am mode.
  • Love at First Sight: What happens when he meets Mirai.
  • Love Makes You Dumb: Watch his post-round interview with Mirai in episode 16; he's definitely struggling to keep a straight face...
  • Next Tier Power-Up:
    • After he upgrades Lightning Gundam with a flight booster in episode 5, he's able to force Ramba "The Blue Giant" Ral drop his shields in a battle, something less than 5 other fighters had ever done.
    • In episode 14, he upgrades Lightning Gundam's flight booster and rifle to create the faster and more heavily armed Lightning Gundam Full Verniern.
  • Real Robot: Compared to Sekai's Build Burning being able to defy the laws of physics with its close-quarters martial arts, Yuuma's Lightning Gundam instead abided to them, and as a result developed a fighting style to accommodate this, including a fighter jet mode for aerial hit-and-run bombardments, as well as a sniper-rifle for long-range fire-support.
  • Retired Badass: The "Six Years Later" short reveals Yuuma used to be a Gunpla Fighter, but retired, which really bummed out Sei. A flashback hints that he lost his confidence in his skill in Gunpla battling after an opponent tore apart his custom Airmaster Gundam while telling him that he has no talent, even mocking the fact that he learned from a former world champ and was the favorite in winning the regionals. Needless to say, it doesn't last, especially after he learns that Fumina is still holding on to their promise of becoming world champs.
  • Surpassed the Teacher: In episode 14 he creates Try Burning by upgrading Build Burning, a suit built by the same person who taught him how to build Gupla, Sei Iori.
  • Taking You with Me:
    • Runs through Sudou's Mega-Shiki with a retaliatory beam saber during the finals of the Tokyo qualifying tournament. Subverted in that Yuuma is still able to continue with the match due to the Lightning Gundam's Lighting Back Weapon System. Double subverted when it's revealed that the Mega-Shiki survived the attempt... barely.
    • In final match against Adou Saga, he rams Gundam The End with his Back Weapon System Mk II and stuffs the enemy's midsection with a barrage of missiles.
  • The Spock: While not emotionless, he is the more level headed member of the group.
  • Transforming Mecha: Has a definite preference for suits that can transform into a Cool Plane: over his career, he's used a Savior, Airmaster, customized Re-GZ, and a customised Zeta.
  • To Be a Master: Joins Team Try Fighters to help him become a master Gunpla builder.
  • Vitriolic Best Buds: If it doesn't come off as Ho Yay, his relationship with Sekai is most certainly shaping up to be this.
  • Why Did It Have to Be Snakes?: Episode 17 revealed that he is afraid of ghosts. The field they were placed in didn't exactly help matters.
  • You Don't Look Like You: In his brief appearance in the original Build Fighters he had short brown hair and didn't wear glasses.

Seiho Academy PlaModel Club

    Daiki Miyaga 
https://static.tvtropes.org/pmwiki/pub/images/daiki_6727.png

Voiced by: Koji Yusa (Japanese), Victor Lee (English)
Main Gunpla: AEU-09Y812 AEU AEU Enact Moralia Development Experiment Type, AEU-MA07013 Agrissa Type 13

A third-year student at Seiho Academy, and president of the Plamodel club. He wants Fumina to leave the Gunpla Battle club and join his club instead. Goes by the nickname "Mantis Man".


  • Abhorrent Admirer: Half of his dialogue toward Fumina screams "sexual predator" in big, bold letters. No longer the case now that he's with Eri.
  • Ace Custom: His Enact is one part Commander Type Enact and one part Ali Al-Saachez Enact. Quite deadly against the heavily armed Powered GM Cardigan, but no match against the Dom-disguised Build Burning.
  • Actor Allusion: Daiki's hair bears resemblance with Obright Lorain. Both share the same voice actor.
  • Animal Motifs: Associated with praying mantises.
    • has the nickname "Mantis man"
    • has a haircut that looks like the head of a mantis.
    • pilots a green AEU Enact Custom which has insect-like proportions.
  • Combat Pragmatist: Brings an Agrissa into the fight in episode 2, since it isn't an official match and is therefore technically not forbidden, and he needs all the firepower he can get.
  • Complexity Addiction: He never ONCE thought to simply ask Fumina out on a date, instead tried to destroy her club by stealing away her club members and later tried getting the student faculty president to close the club altogether.
  • Entertainingly Wrong: Daiki thinks that Gunpla Battle is pointless because of the risk of destroying one’s precious Gunpla, not once mentioning the model damage levels that have been introduced into the system to address this very issue. And this change would have already been in place for years before Try began.
  • Geek Physiques: He's a tall and lanky fan of model building.
  • Love at First Sight: Kind of. He's known Eri for quite some time, but has never seen her without her glasses. He falls hard when he finally does.
  • Murder the Hypotenuse: A strange case, in that the hypotenuse in question isn't a person but instead the Gunpla Battle Club. The way in which he goes to ludicrous lengths to close Fumina's club to try and force her to join his Plamo Club, he basically treated the Gunpla Battle Club as the competition!
  • Sickeningly Sweethearts: He and Eri are all over each other in episode 3. The way they talk of building a model kit (an MS Girl, no less) together sounds like something else, to the horror of Team Try Fighters.
  • Smug Snake: Oh, so much so. He takes great glee in pointing out that all of his Plamodel Club members joined after being disillusioned by losses. Once more, we have Eri to thank for him dropping the attitude, enough that he doesn't even mind Yuuma leaving the club.
  • Spanner in the Works:
    • He challenges Sekai and Fumina to a Gunpla Battle with the intent on shutting down the Gunpla Battle Club after beating them. He had no idea Sekai would become an ace and utterly wreck his Enact.
    • In the episode 2 match, Yuuma turns on Daiki when the model club president uses underhanded Loophole Abuse to tip the odds in his favor.
  • Took a Level in Kindness: In Episode 3, he is much nicer after hooking up with Eri.

Voiced by: Ai Kayano (Japanese), Jessica De Borja (English)
Main Gunpla: RMS-116H Hobby Hizack

A second year student at Seiho Academy, and vice-president of the Plamodel club. She adores President Miyaga and fully supports him in all endeavors.


  • Beautiful All Along: She reveals herself to be surprisingly good looking without her glasses and braids. It could almost be considered a parody, since her braids spontaneously come undone as she takes off her glasses, and then she and Daiki spend the rest of the scene surrounded by pink Love Bubbles (even in wide shots).
  • Hime Cut: It looks accurate (long length, even bangs, and pigtails instead of sidelocks) and she is the club vice-president, but the personality traits are off (ditzy and fliry for two things).
  • Leeroy Jenkins: She charges in to create an opening only to get her Hizack two-shotted by Fumina. Of course, she may have done it on purpose (as Fumina seems to think).
  • Obfuscating Stupidity:
    • Acts like a ditz when she gets eliminated from the battle. Fumina later comments that she probably got herself taken out on purpose.
    • She initially seems like the typical meek nerd girl. Turns out she's a lot more flirty than one would expect once she loses the glasses and braids.
  • Scary Shiny Glasses: Her eyes are always obscured by the opaque white frames of her glasses.
  • Sickeningly Sweethearts: See above, though moreso on her part.
  • Undying Loyalty: Will do anything for her club president, Daiki.

Regional Qualifiers Rivals

    Kaoruko "Gyanko" Sazaki 
https://static.tvtropes.org/pmwiki/pub/images/kaoruko_4872.png

Voiced by: Ryō Hirohashi (Japanese), Terri Oliver (English)
Main Gunpla: AMX-104GG R-Gyagya, YMS-15KRT02 Gyancelot

Susumu Sazaki's little sister, now a Gunpla Battler herself, and Team Captain of St. Odessa's Gunpla Battle club.


  • Abhorrent Admirer: How Fumina treats her crush on Sekai, as Gyanko leads a rival team. Sekai himself is too dense to even notice.
  • Ancestral Weapon: Her R-GyaGya's missile shields were given to her by her big brother Susumu.
  • Ascended Extra: She is Susumu's younger sister, who briefly appeared in episode 25 of Build Fighters. In Try, she leads one of the rival teams and is a Love Interest for Clueless Chick-Magnet Sekai.
  • Big Brother Worship: She was her brother's biggest fan, and took up his preference for fighting with Gyan based Gunpla. Her R-GyaGya shows clear inspiration and influence from his Gyan Vulcan.
  • Biting the Handkerchief: Bites down on her ascot when she sees Fumina hugging Sekai in episode 5, mirroring her brother biting down on his handkerchief after seeing Reiji piloting Sei's Gunpla in the tournament instead of him 7 years earlier.
  • Casting Gag: Has the same voice actress as her older brother.
  • Clingy Jealous Girl: Considering her Biting the Handkerchief reaction to Fumina hugging Sekai in episode 5, she's definitely coming off as this.
  • Composite Character: Her R-GyaGya is a combination of the R-Jarja from Mobile Suit Gundam ZZ and the Gyan from Mobile Suit Gundam.
  • Everyone Calls Him "Barkeep": Except for her lackeys, everyone who knows her calls her "Gyanko" since her elementary school days, due to her preference in gunpla model. It even extends to This Very Wiki given how often she's referred to as "Gyanko" as opposed to her actual name.
  • Fake Tears: In episode 8, while attempting to get Sekai's attention. She even had a small bottle of it for good measure.
  • Girlish Pigtails: Worn up with hair decorations that look like the Gyan's missile shields.
  • Girly Run: During the post-credits stinger of Episode 3. See Defeat Means Friendship entry.
  • In-Series Nickname: "Gyanko"note , combining "Gyan" with a feminine name suffix.
  • The Leader: She's the leader of Team Song Dynasty Vase.
  • Lovable Alpha Bitch: Like her brother, she's haughty and arrogant. Unlike her brother, she's a fair fighter and a Graceful Loser.
  • Macross Missile Massacre: Like her brother's Gunpla, her R-GyaGya can launch a stream of missiles from its shields.
  • Mythology Gag:
    • Named her team after the favorite vase of M'Quve, the pilot of the Gyan in Mobile Suit Gundam.
    • Her R-GyaGya is based on the R-Jarja from Double Zeta, a suit which in itself was inspired by the Gyan. Just like how she was inspired by her brother Susumu and his Gyan based Gunpla.
  • Proper Tights with a Skirt: Her school uniform.
  • Rescue Romance: She develops a crush on Sekai when he stops her R-GyaGya from falling out of the arena after he beats her in episode 3.
  • There Is Another: Played for Laughs. Turns out, she's not the youngest Sazaki sibling. Like her own reveal, the finale reveals yet another younger sibling, Tateo, the spitting image of Susumu. Yet another is mentioned, earning the Sazakis a comparison to the Zabis.
  • Those Two Guys: She and Shimon become the Sekai cheerleader squad after the preliminary tournament arc.
  • The Worf Effect: She and her team were hit hard by this in Episode 8, specifically to showcase the strengths of Team G-Master.
  • Your Size May Vary: Multiple times in the same Episode (and even scene) depending on the art director in charge. It is especially noticeable in the Island Wars OVA, when hugging onto Sekai's arm in an attempt to be "cute", Gyanko suddenly shrinks to a slim and beautiful typical Bishoujo girl's design, only to inflate back to her usual self in the next shot when she lets go.

Main Gunpla: ZGMF-X42S Destiny Gundam, ZGMF-X56S/θ Destiny Impulse Gundam

A gifted athlete who was set to become a junior high boxing champion, but he left to take up Gunpla Battle.


  • The Ace: A former junior high boxing champ who is exceptionally good at Gunpla battling, and is recognized as the man solely responsible for his team reaching such a high place in the regional matches. He even gave Sekai a run for his money using only a straight build Gunpla.
  • Badass Normal: He's perfectly capable of kicking ass using only an out-of-the-box Gunpla, something that is explicitly said to be of lesser quality than a handmade custom Gunpla.
  • Big Brother Instinct: Shimon became involved in Gunpla Battle to encourage his sick little bother, who loves Gunpla, with his recovery process.
  • Blood Knight: To say he enjoyed his no-holds-barred match with Sekai is an understatement.
  • Boxing Battler: Uses his boxing skills in Gunpla Battles.
  • Cool Big Bro: Definitely comes off as one to his brother and his teammates.
  • Defeat Means Friendship: He became friends with Sekai after their match even training him for his match against G-Masters
  • Empowered Badass Normal: Downplayed. In the final episode's free-for-all, he's using Mamoru's Destiny Impulse, which is a well-crafted competition level Gunpla, meaning he's now far more deadly than his straight-built Destiny Gundam. However, he's not shown engaging with any of the significant combatants.
  • Nice Guy: Very respecting of his opponents, his teammates and very kind to his little brother.
  • Pointless Band-Aid: Has one on his left cheek.
  • Those Two Guys: He and Kaoruko become the Sekai cheerleader squad after the preliminary tournament arc.
  • Weak, but Skilled: He uses straight-out-the-box gunpla, which has the lowest possible performance, but is still a major threat. The title of the episode he shows up in even points this out.

Main Gunpla: ZGMF-X42S Destiny Gundam, ZGMF-X56S/θ Destiny Impulse Gundam

Shimon's little brother, who has a congenital health condition.


  • Back for the Finale: Doesn't appear after Shimon's battle with Sekai, but returns for the finals, recovered enough to watch live and shortly after, to participate in the Meijin Cup, even gaining some focus.
  • Delicate and Sickly: The reason Shimon even playing Gunpla battles is so he can win for his younger brother.
  • Friendly Enemy: He's super impressed with Sekai's Build Burning, and is happy to know his brother will still be able to fight challenging opponents.
  • From the Mouths of Babes: Played for Laughs with his question to his brother in Episode 24. Shimon's immediate reaction sells it.
    Mamoru: (Towards the girls from St. Odessa) So nii-san... Which of them is your girlfriend?
  • Irony: Builds out of the box only for it to lose to a custom. When he finally builds a custom for the Mejin Cup, it loses to a plain Gyan.
  • Soap Opera Disease: It's never explained what he's suffering from, only that it's forced him to stay in the hospital and go through a number of treatments and / or rehab work to recover. By the finale, he appears to be well enough to be out of the hospital for an extended period of time.
  • Signature Style: He loves Destiny Gundam, building both a plain Destiny Gundam and later a custom 1/144 size Destiny Impulse Gundam for Shimon to use.
  • Worthy Opponent: Recognized as this by Gyanko's younger brother Tateo, though it's more clearly a friendship than pure rivalry, not that the latter's ego would admit it.

Main Gunpla: AMS-129 Geara Zulu, MSN-001M Mega-Shiki

Leader of Miyazato Academy's Team G-Master.


  • Cool Bike: Mega-Shiki's backpack can transform into a space motorcycle with a Wave-Motion Gun on the front.
  • Determinator: Even after his Mega-Shiki is all but destroyed, he still goes ahead and tries to land a punch on the equally crippled Build Burning Gundam. Unfortunately, the latter's nigh invulnerable construction means that he ends up wrecking his remaining arm and totally crippling the Mega-Shiki, causing his team to lose the match. He's also mentioned that he sacrificed his pride as a builder, commissioning the Mega-Shiki from Minato instead, just to give him a shot at getting back into the National Championship.
  • Good Is Not Soft: He might be a nice guy, but he can be absolutely ruthless in battle.
  • Graceful Loser: He smiles right after he loses and even apologizes to Sakai for losing despite using his Gunpla.
  • Heroic Second Wind: Just as everyone thought it was all over, he appeared at the end with his badly damaged Mega-Shiki. As his damaged Mega-Shiki floats towards the equally damaged Build Burning, he talks about how he threw his away his pride as a builder by using a gunpla that someone else built for him, all for the sake of his dream; of going back to the nationals. He then proceeds to use everything Mega-Shiki had left and punches Build Burning in the face. Averted, because it didn't work.
  • Hoist by His Own Petard: He's defeated when his damaged Mega-Shiki punches an equally damaged Build Burning Gundam in the face. The Mega-Shiki's arm shatters, disabling the unit.
  • The Leader: He's the leader of Team G-Master.
  • Purple Is Powerful: His upgraded Mega-Shiki is painted purple, instead of the Hyaku-Shiki's standard gold.
  • Moe Anthropomorphism: His haircut and clothing evoke a cute kid version of the Frost Brothers from After War Gundam X.
  • Nice Guy: Outside of a battle, he is kind and very respectful towards his opponents
  • Wave-Motion Gun: Mega-Shiki's backpack can turn into a "Mega Bazooka Launcher" that shoots a giant particle beam that can wipe out even warships in a single shot.

  • Official Couple: With Akira. She's still a Tsundere about it, though.
  • The Smurfette Principle: The lone girl on the 3-person Team G-Master.

A new transfer student at Miyazato Academy who joins Team G-Master.


  • Combining Mecha: Does an impromptu version with his G-Bomber and Yomi's Amethyst Victory Gundam after both re badly damaged by Sekai's Build Burning Gundam.
  • Cool Car: Seen on episode 20 driving what looks like a Volkswagen New Beetle convertible. However...
  • Drives Like Crazy: He only got his driver's license two days prior to picking up Junya from the tournament arena. Cue the latter wanting to get out of the car. Yomi later gets a taste of it, with a cheerful Akira none the wiser.
  • Expy: His mannerisms and appearance are heavily based on Sleggar Law from Mobile Suit Gundam. To the point where he's called a "Sleggar" in episode 8.
  • Fighting Clown: The man looks like a lazy joke, walking in and demanding to join the team. Then he kicks Meguta's Zeo Zeong's ass and reveals he came from the Gunpla Academy, the same place Allan, Yuuki and Julian all trained at.
  • Get A Hold Of Yourself Man: Does this to Yomi to knock some sense back into her, after she became so drunk with victory that she starts trash talking her opponents who'd fought with all their strength.
  • Graceful Loser: He happily congratulates Sekai and Fumina for their win when he sees then again.
  • Improbable Use of a Weapon: His plane knows kung fu. It has to be seen to be believed.
  • Martial Arts and Crafts: Manages to use martial arts blocks and holds in order to defeat Team Song Dynasty Vase's humanoid Gunplas, despite using a non-humanoid Gunpla himself.
  • In-Series Nickname: He went by the moniker "Speedy Sleggar" during his time at the Gunpla Academy.
  • New Transfer Student: Transfers to Miyazato Academy in episode 6. Episode 7 reveals that he came from the private Gunpla Academy.
  • Nice Guy: He respects his opponents that fought with all their might
  • Official Couple: With Yomi.
  • Odd Friendship: Following Junya's Heel Realization, Akira makes up with him and is open to battling with him again. And then there's the matter of Akira's "driving skills" and Junya's reactions to it.
  • Race Lift: He is clearly Japanese, whereas his base was every bit Americannote .
  • Sixth Ranger: Joins G-Master in episode 6, disrupting the established Power Trio dynamic of the team.
  • Underestimating Badassery: While he can effectively counter the Jigen Haoh, he completely under-estimated Sekai's skill and ability to find ways of getting around it.

  • Token Mini-Moe: He is the youngest member of Team G-Master, and also the most prone to cartoon-ish expressions and over-excitement.

Main Gunpla: GN-9999 Transient Gundam

Allan Adam's nephew and the leader of the Gunpla Academy Team. He aims to become the fourth Meijin Kawaguchi.


  • The Ace: He's the Gunpla Academy's best fighter. Episode 13 reveals that he was trained by none other than Julian Mackenzie, a former candidate for the Meijin Kawaguchi name.
  • Attack Drone: The GN Partisan can split into two "Lance Bits" that can either slash or blast targets. With episode 23, he adds a second Partisan, raising the count to 4 bits.
  • Beam Spam: Transient Gundam's main attack involves generating dozens of beams to fire simultaneous at enemies.
  • Blood Knight: He's looking for a Worthy Opponent. Even Adou Saga admitted that Wilfred was more battle hungry than him.
  • But Not Too Foreign: Half European, half Japanese.
  • Composite Character: His Transient Gundam is the prototype design for Gundam Exia mixed with 00 Quanta Full Saber and Tekkaman Blade.
  • Dude Looks Like a Lady: Has androgynous features.
  • Friendly Enemy: Gets pissed when one of the other national tournament team members looks down on one of his opponents, Sekai.
  • Hot-Blooded: While he acts like The Stoic out of battle, when in a serious Gunpla battle he tends to get overly fired up.
  • Implausible Fencing Powers: Stops a barrage of beam fire by intercepting one shot with his spear, splitting it and causing it to intercept all the other shots, forming a geometric "barrier".
  • Large Ham: When he gets going, he really gets going.
  • Let's Fight Like Gentlemen: Discards his GN spear and battles the Build Burning with nothing but bare-handed fighting techniques.
  • Lonely at the Top: He's constantly searching for the fighter who can give him a good match, but is almost always disappointed. Furthermore, the one person who can match him happens to be his own teammate.
  • Mythology Gag:
  • Serious Business: He takes Gunpla battles very seriously, and chastises those who are not willing to give it their all when battling.
  • Spell My Name With An S: Is it Wilfred or Wilfrid?
  • Super Mode: Transient's Transient Burst is basically its version of the Trans-Am, along with a nifty pair of energy wings.
  • Suspiciously Similar Substitute: Borrows a lot from Tatsuya Yuuki in the original Build Fighters, as a rival who loves Gunpla, has strong sense of honor, and seeks to become the next Meijin Kawaguchi. Allan even tells Wilfred that he reminds him greatly of Yuuki in episode 23.
  • White Gloves: Wears gloves on his hands as part of his stylish look.
  • Worthy Opponent: He only gives his all against opponents who do likewise, and treats them with great respect. As he did in his battle against Sekai.

Main Gunpla: Cruel Gundam, RX-END Gundam The End

A Key member of the Gunpla Academy Team. Two years before the start of Try, he defeated Yuuma in a Curb-Stomp Battle that caused Yuuma to retire from Gunpla Battle.


  • Arch-Enemy: Yuuma's, as the sniper is obsessed with beating him. However, when Yuuma calls him out on it, Adou responds that he's fought nearly every single day in the meantime, and expecting him to remember one specific battle out of two years' worth is absurd. However other hints suggest he does remember, but claims not to anyway to further get under Yuuma's skin.
  • Blood Knight: He's constantly looking for strong opponents to fight, but the only person he considers an equal is his teammate Wilfred.
  • Breaking Speech: Gives one to Yuuma two years ago, while tearing his gunpla to shreds.
  • Composite Character:
    • The Cruel Gundam is a Hydra Gundam with elements of the Endless Waltz Deathscythe Hell and Altron, plus Arche Gundam's fangs.
    • His Gundam The End is an original design but seems to have elements of the Hydra Gundam, Deathscythe Hell, Devil Gundam, Regnant, Superbia GN-X, Garazzo and a custom revolver / bullet gimmick.
  • Curb-Stomp Battle: He defeated Team White Wolf all by himself offscreen...... and mocks them. And then he handily does the same to Try Fighters.
    • Also did this two years ago to Yuuma, which prompts the latter's shellshock and retirement from Gunpla Battle.
    • Gets on the receiving end of the curb-stomp courtesy of Meijin Kawaguchi III, who neutralized all of his attacks. The battle was cut short, but as his team mate points out, even he knows he would've lost if the battle continued.
  • Dark Is Evil: Downplayed. While not evil, he is probably the biggest Jerkass in the series thus far. And to match this, his Gunpla can look absolutely demonic at times.
  • Defiant to the End: Non-fatal example, but despite a Doctor storming out and revealing that his hand isn't in good enough condition to battle, and that his usage of his Fangs is actively worsening it's condition he keeps on fighting anyway until the battle's done because he's having the time of his freakin' life
  • Heroic RRoD: Minus the heroic part, of course. Due to two points of abusing his right hand (punching the wall at Nielsen Labs after Meijin nearly hands him his ass, then banging on the semi-finals selection machine) and not getting it treated, by the end, it's damaged enough that he still has to have it checked after the Meijin Cup. During the finals, however, it holds long enough, using all his fingers to control every Fang until Yuuma takes him down.
  • Jerkass: As a Blood Knight, he finds anyone too weak to compete with him worthless, and openly tells them so. He also tends to destroy opponents Gunpla, hoping that pushing them into a corner will make them fight harder.
  • The Juggernaut: He can solo entire teams without taking so much as a scratch.
  • Laser-Guided Karma: The only member of the main cast shown in the final credits sequence that got an unambiguously bad deal as his reckless use of his injured right hand causes it to become damaged to the point where he needed to go to the hospital to get it checked out, making it a potentially Career-Ending Injury. Not even Junya suffered something like that.
  • One-Man Army: Annihilates both Team White Wolf and Try, in a row, alone.
  • Token Evil Teammate: Not so much evil, but Saga is a massive Jerkass and definantely fills this spot on Team Celestial Sphere. To the point that Meijin Kawaguchi specifically tells their coach to rein him in.
  • You Don't Look Like You: In Yuuma's flashback, Saga has different hair, specifically long, black, and wavy.

Main Gunpla: GNW-100P Gundam Portent, GNT-0000S Gundam 00 Shia Quan[T]

Allan Adam's niece, she returns from studying in England to join the Gunpla Academy's regular team. She is seen as a candidate by Lady Kawaguchi as her potential successor.


  • Action Girl: Is the third member of the championship winning Gunpla Academy team. Even an ace like Lady Kawaguchi acknowledges her skills.
  • Apologetic Attacker: Doesn't like hurting Gunpla and apologizes to them before kicking their asses.
  • Badass Adorable:
    • She's very cute and She solos and defeats Kei Karima's Vagan Gear K all by herself with her recently completed G-Portent with her brother and Adou standing by, not even joining the tournament round battle at all, and she does it without even taking any damage in a complete and utter curbstomp in episode 16.
    • The G-Portent itself can only be described as beautiful, in both craftmanship and an aesthetic sense.
  • But Not Too Foreign: Half European, half Japanese.
  • Character Tics: She often bows elegantly, and even makes her G-Portent do it.
  • Clingy Jealous Girl: Not as much as Gyanko, but she definitely shows shades of this in Island Wars.
  • Dance Battler: Shia's fighting style is best described as being similar to a ballerina's performance, using gentle elegant movements while dodging attacks, and a smooth flawless stroke when attacking. Lady Kawaguchi even calls her a prima, the term that is usually given to the best ballerina.
  • The Engineer: She's the one who tunes and repairs the Gunpla Academy's gunpla.
  • Every Proper Lady Should Curtsy: She bows before and after she fights.
  • Expy: Visually, she's very similar to Aila. Less obviously, sensing the feelings of machines (in this case gunpla) and surfing on the beams in episode 16 are reminiscent of Eureka of Eureka Seven.
  • Friendly Enemy: Teaches Sekai how to tune up Build Burning Gundam, reasoning "fighting a weak Gunpla would be boring".
  • Lady of War: Her combat style is extremely elegant, almost ballet-like. Lady Kawaguchi calls her a "prima", and not in the negative sense that "prima donna" is sometimes used in. The opera gloves she wears are a subtle way of emphasising her elegance, too.
  • The Tease: She loves to flirt with Sekai, which drives Fumina and Gyanko up the wall.
  • Ultimate Blacksmith: Minato Sakai proclaims her as the best builder at the U-19 Nationals, better even than he and Yuuma, the best builders in Kansai and Kanto.
  • Unknown Rival: For Fumina, who sees her as a first step to become a fighter as skilled as Lady Kawaguchi. Shia on the other hand, has absolutely no idea that Fumina sees her as a rival. Shia does finally acknowledge Fumina's skill in episode 19, though she still has no idea that the latter see's her as a rival. Or that Lady Kawaguchi considers them both as candidates to succeed her.

Voiced by: Kazuyuki Okitsu (Japanese), Victor Lee (English)
Main Gunpla: Kouki Gundam, MSN-001M Mega-Shiki, Gundam Tri-Zeta, The Strongest Machine Gundam Tryon 3, SF-01 Super Fumina, Super Fumina Titans Maid ver., MSZ-008ZZ ZZ II, Gundam Dryon Drei

An Osaka based master builder, and rival of Yuuma Kousaka. As a disciple of the Gunpla Shingyo School, Minato sees himself as superior to the Gunpla Builders of Tokyo.


  • Abhorrent Admirer: One for Fumina, though it's less his looks and more his attitude. Acting like Mao probably won't help anyone's chances. Taken to its extremes when his entry in the Meijin Cup is an MS Girl that's clearly designed to be Fumina. It's a source of embarrassment to Fumina and earned him a scolding from Meijin for not getting Fumina's consent to have an MS Girl made to her likeness, costing him the Cup.
  • Always Someone Better: How he feels about Yuuma. He hates it when people think of him as a replacement to him. Which is ironic considering Yuuma apparently looks at him the same way (when the latter saw his works in Ep. 4).
  • Animal Motifs: His Tryon 3 is a combination of three animal robots: a lion, a manta ray, and a falcon.
  • Awesome, but Impractical: The Tryon 3 is this. As pointed out by Yuuma, it risks structural integrity and joint strength (plus loses the two other units on the team) for well... being a freakin' combining super robot. On the flipside, being Boring, but Practical is considered in-universe to limit the potential of a custom Gunpla. Iori Sei in the original series only started improving after he decided to toss out standard Gundam series tropes in terms of functionality out the window and did his own thing, as shown on the Star Build Strike. The Gunpla Shigyo School emphasizes creativity and originality over following 'the rules' in terms of design, and Minato makes that work beautifully, as despite the weaknesses the Tryon 3 should have according to Yuuma, it's still an unbelievably powerful Gunpla, capable of wasting entire teams of customs by itself without any structural problems at all.
  • Badass Cape: The SD Kouki Gundam he used against Sekai has one.
  • BFS:
    • The SD Kouki Gundam, which he uses against Sekai in their first battle, has a super sized beam saber.
    • He then cranks it up with the Tryon 3's "Hyper Minovsky Chohoken", which he then uses as a Finishing Move on the Try Fighters.
  • Broken Pedestal: It turns out that the animosity he bears towards Yuuma was because he used to admire the Tokyo builder when he was still a fighter up until he gave up on Gunpla Battle. Yuuma returning to being a fighter only served to anger Minato more, as it made the builder from Osaka feel as if Yuuma wasn't really taking the sport seriously with all his flip floping back and forth.
  • Bunny-Ears Lawyer: Minato is a great Gunpla builder like Mao before him, but he thinks he can get away with making an MS Girl in Fumina's likeness without asking her first to win the Meijin Cup. Meijin himself gives him a What the Hell, Hero? for it, because one of the basics of being a builder (and an artist in general) is to get permission before using anyone's likeness as a reference.
  • Call-Back: The Super Fumina is clearly designed after her namesake's first shown Gunpla, the Powered GM Cardigan
  • Calling Your Attacks: His first battle with Sekai has him doing this. Also, his Tryon 3 is a Super Robot Combining Mecha, so he also gets to call its attacks, as per tradition.
  • Combining Mecha: Tryon 3, which is a Shout-Out to the Super Robot genre.
  • Comically Missing the Point: The entire incident with the Super Fumina. He's so focused on trying to beat Yuuma that he doesn't see anything wrong with what he built or if it was okay to do so without the person's permission.
  • The Engineer: Builds the Mega-Shiki for Shunsuke Sudou. Assembles the Kouki in ten seconds. Also builds team Build Busters giant Gunpla, Tryon 3, on his own. And surely some engineering miracle was involved when he operated all three parts of the Gundam Dryon Drei during Build Fighters Battlogue.
  • Fantastic Racism: He often complains about the residents of Tokyo being rude and uncultured. It get rather silly when he tries to order iced coffee using an old Osakan word for it.
  • Finishing Move: Tryon 3's Hyper Minovsky Chohoken Tryzan, to which Minato busts out on Try Fighters. Downplayed, considering that it only took Sekai and Fumina out of the battle, giving Yuuma a chance to finish it.
  • Heart Is an Awesome Power: The Gunpla Shingyo School teaches you to "model your heart". As silly as this sounds, it's made Sakai an excellent battler and builder. He even gives a Badass Boast about it while defeating Sekai in their first encounter.
    Sakai: Gunpla is freedom! Amid that limitless freedom, I materialized my thoughts. Yes, this is the model of my heart!
  • Hot-Blooded: Most evident when battling in the tournament, channeling various Super Robot pilots while piloting Tryon 3.
  • I Am Your Opponent: To Sekai, when the latter was battling kids at the G-Muse Gunpla shop.
  • Idiot Hair: Has a tuft poking out near his forehead. (See pic.)
  • Irony: After failing to convince Yuuma into quitting the Gunpla Battle Championship and enter the Meijin Cup multiple times, he forgoes the chance to enter and joins his school's battle club specifically to enter the Nationals and fight Yuuma.
  • Insufferable Genius: He's a master builder and knows it, always taking a chance to talk down to others or look smug.
  • Jerkass Has a Point: Despite his nasty and condescending attitude towards Sekai, believing him to just be some talentless loser who won't amount to anything, he ends up helping Sekai realize that he had just been relying on brute force in all of his battles thus far, which makes him sit down and reevaluate his approach to Gunpla Battling. As a result, Sekai's skill in controlling the Build Burning Gundam vastly improves. At the same time, his encounter with Sekai also indirectly helped Fumina find the inspiration she needed to build the Winning Gundam.
  • Land, Sea, Sky: Sora Tryon, the falcon, Umi Tryon the manta ray, and Riku Tryon, the lion.
  • Laser Blade: Of the BFS variation with the Hyper Minovsky Chohoken, which Minato pulls out from the Riku Tryon's mouth for its Finishing Move.
  • Large Ham: His debut in the National Tournament was so over the top that it left the entire arena speechless. Including Meijin and Lady Kawaguchi.
  • Nice Job Fixing It, Villain: A more minor example, but it was thanks to Minato’s taunting of Sekai during their battle at G-Muse that lead to Sekai figuring out a way to more effectively use his Kenpo in Gunpla Battle, and helped inspire Fumina to create her Winning Gundam. Both of which paved the way for literally all that the Try Fighters do in the rest of the series.
  • Open Mouth, Insert Foot: How he described the proportions of the Super Fumina:
    Minato: The waist is even 10% thinner than the real Fumina!
    Fumina: SHUT UP!
  • Paper Tiger: His first opponent in the Gunpla Battle Nationals declares the Tryon 3 as this. He easily proves him wrong.
  • The Rival: To Yuuma. Though prior to Episode 22 Minato was more of the Unknown Rival type.
  • Rocket Punch: Armed Booster, one of the attacks of the Tryon 3. Even gets called as such by their enemies.
  • Stalker with a Crush: Unlike his predecessor, Mao, who got to know his love interest Misaki through friendship and getting on her good side, it's shown throughout Try that Minato creeps Fumina out. Minato making the Super Fumina at the end of the series did not help his case, because unlike Mao, who received a slap from Misaki in going too far in their relationship too soon and thus wisened up, Minato did not even realize what he did was wrong even when both Meijin and Fumina were telling him off for not getting Fumina's permission.
  • Super Robot: His Tryon 3 borrows gimmicks from super robot shows like GaoGaiGar and other robots from the Brave Series.
  • This Cannot Be!: He's shocked Sekai, the kid he beat in episode 4, is masterfully piloting a championship level Gunpla in episode 5.
    Minato: I THOUGHT YOU WERE JUST A LOSER!
  • Transformation Is a Free Action: Enforced. The Tryon 3 has a barrier during its Transformation Sequence.
  • Wake-Up Call Boss: Shows Sekai that he can't simply brute-force his way to victory like he did in previous battles.
  • Wave-Motion Gun: Tryon 3's Hyper Mega Cannon, which can be augmented with the back-mounted Double Cannonade and the Liger Glare. Was enough to overpower the combined maximum output of both the Winning Beam and the blast from Lightning's two High Beam Rifles.

    Junya Inose 
Voiced by: Hiroyuki Yoshino (Japanese), Victor Lee (English)
Main Gunpla: NK-13J Denial Gundam

A powerful but ruthless Gunpla Battler who fights using Jigen Haoh, the same martial arts style Sekai practices.


  • All There in the Manual: The fact that he got his Denial Gundam from the 2nd Meijin is only mentioned in supplementary materials.
  • Bare-Fisted Monk: Uses punch and kick techniques, like Sekai.
  • Bequeathed Power: Just like Sekai ended up with Sei Iori's Build Burning Gundam, Junya's Denail Gundam originally belonged to former Gunpla Battle champion Meijin Kawaguchi II.
  • Big Brother Mentor: Served as this to Sekai while they were both training, but...
  • Broken Pedestal: Not being bequeathed the ultimate secrets of the Jigen Haoh school turned him into this.
  • Combat Pragmatist: Unlike Sekai, Junya doesn't rely exclusively on Jigen Haoh but also uses moves from aikido, Chinese martial arts, even boxing.
  • Dark Is Evil: His gunpla is dark gray and purple, and has purple-black flames instead of red ones like Sekai.
  • Despair Event Horizon: By not being given the ultimate secrets of Jigen Haoh, he falls so badly that he decides that if he can't get it, he'll beat power out of everyone.
  • Dull Eyes of Unhappiness: His eyes have no shine in them, ever. He's forever empty and pissed looking.
  • Evil Counterpart: To Sekai, as a fellow practitioner of the Jigen Haoh school of martial arts who uses a suit built by a championship level Gunpla Battler, but only cares about destroying his opponents.
  • Green-Eyed Monster / The Unfavorite: Junya is apparently treated by Sekai's master as a less-than-ideal student of the Jigen Haoh-ryu, considering he was not granted the final/succession techniques. Learning that Sekai apparently has been rankles him very much.
  • Heel–Face Turn: After Sekai beats him, he changes his ways. During the "Where Are They Now?" Epilogue, he returns to train in Jigen Haoh-ryu with Domon.
  • Heel Realization: He realizes Sekai's resolve about finding his own strength and sheer determination once Sekai beats him, ultimately deciding to start over, and returning to the Jigen Haoh school of martial arts in the "Where Are They Now?" Epilogue.
  • In the Hood: Can always be seen in a dark green hoodie, with the hood up, adding to his mysterious image.
  • Jerkass: Shows up in episode 14 just to annoy Akira about his loss to team Try Fighters.
  • My Kung-Fu Is Stronger Than Yours: As he boasts to Sekai as he's beating the shit out of him, he has the technique, but not the skill.
  • Meaningful Name: Denial Gundam's MS code starts with "NK", the initials in "Nidaime* Kawaguchi".
  • Not So Above It All: In episode 20, after having a spectacular Gunpla Battle with Sekai, he gets picked up by Akira with his car. He then finds out that the latter only got his drivers's license two days ago. Cue to him frantically wanting to get out of the car.
  • Used to Be a Sweet Kid: Was very kind and supportive of Sekai when they were both in training.

Main Gunpla: Zaku Mánagarmr

Leader of Gabai Institute's Team White Wolf from Kagoshima Prefecture.

  • Ace Custom: uses a white Zaku with a wolf-themed color scheme.
  • The Worf Effect: he is a skilled Gunpla fighter, won the regionals from his home prefecture and entered the nationals four years in a row, but gets owned by Gunpla Academy twice before getting utterly defeated by Lucas Nemesis.

Main Gunpla: GN-006 Cherudim Custom, Vagan Gear K, XMA-01 Rafflesia

A national tournament competitor from Kanagawa's Honmoku Academy. His team, Team Great K, uses a mobile armor in combat.


  • Butt-Monkey: Probably is starting to build up as the Rainer Cziommer of Build Fighters Try.
  • Didn't Think This Through: He built a 1/144 Rafflesia Mobile Armor for the Meijin Cup and it's an incredibly impressive build that must have taken some time to make. Especially given that there isn't a 1/144 Rafflesia kit, making it a complete scratch build. However, it's disqualified from the contest because it exceeded the size limit, something that surely would've been included in the rules. He still thought it would win.
  • Fatal Flaw: Kei marches to the beat of his own drum, no matter what. This leads him to believe a bit too much of his own hype and overestimate his chances in battles. It also causes him to completely ignore the rules of the Meijin Cup and make a scale model that far exceeds the size limit.
  • I Am Not Left-Handed: Has a mobile armor that he refused to use in the academy because it would "tip his hand" come the nationals.
  • Insane Troll Logic: Tries to pick a fight with Sekai, reasoning that since Sekai fought Adou, he would be able to gauge how to fight the Gunpla Academy by fighting Sekai.
    • He believes in his assured victory at the Meijin Cup in the final episode, despite the fact that his entry, a 1/144 Rafflesia, was disqualified for apparently exceeding the size limit.
  • Jerkass: Acts extremely arrogantly, to the point where Wilfred calls him out on it.
    • Attacks everyone in the battle royale in the final episode simply for ignoring his perceived superiority. It's Toshiya's turn to call him out on it, but he ignores it.
  • Macross Missile Massacre: Fires one helluva barrage against Shia's G-Portent, to no avail.
  • Running Gag: No one ever seems to remember him, much to his constant annoyance.
  • Small Name, Big Ego: Played with. He is a skilled fighter, being able to get into the national tournament twice. He, however, inflates his importance to other fighters, who find him very unmemorable, especially Team SDR, who fought him in the last tournament. The two matches he had were also had him on the receiving end of a Curb-Stomp Battle, courtesy of the Gunpla Academy.
  • Sore Loser: When he finds out that his Rafflesia didn't win the Meijin Cup (it got disqualified), he attacks everyone in the battle royale with Bugs, leading to everyone teaming up to get rid of them and put him in his place.
  • The Worf Effect: His team's mobile armor barely stood a chance against Shia's G-Portent.

Kazuya

Voiced by: Ayumu Murase (Toshiya), Haruhisa Suzuki (Nobuya), Tomoya Kousaka (Kazuya)
Main Gunpla: S×D×G Gundam (Consists of Snibal (Toshiya), Drago (Nobuya) and Gira (Kazuya))

A team composed of identical triplets — Toshiya, Nobuya, and Kazuya Shiki.


  • Always Identical Twins: They're triplets with the same face. The only difference between them is slightly different clothes and hairstyles.
  • Animal Motifs: Dragons.
  • Awesomeness by Analysis: They keep records on the backgrounds and abilities of all their rivals. Except Kei Karima, as everyone seems to forget he exists.
  • Badass Adorable: use 3 customized SD gundams.
  • But for Me, It Was Tuesday: They don't remember battling Karima in last year's national tournament, much to his chagrin.
  • Combat Pragmatist: Unlike other fighters, they employ guerrilla tactics in their matches.
  • Combining Mecha: Their Gundams are capable of combining into one machine, the monstrous Snibal-Drago-Gira.
  • Good Costume Switch: In the final episode, their Snibal-Drago-Gira has been repainted gold.
  • Heel Realization: Upon being defeated by Team Try Fighters, Toshiya remembers what Gunpla Battle is truly about — finding joy in your passion.
  • The Leader: Toshiya, of the Mastermind variety.
  • Not Good with Rejection: Non-romantic, but nevertheless a HUGE understatement. Toshiya's application to the Gunpla Academy being rejected upset him so much that he developed a grudge. He let that grudge fester until it turned into an abomination, personified by his team's trump card.
  • Same-Sex Triplets: All three of them are male.
  • Suspiciously Similar Substitute: Borrow a lot from Mario and Julio Renato in season 1, blue haired twins who used various war tactics in Gunpla battles.
  • Those Two Guys: Nobuya and Kazuya. Toshiya is the one who gets most of the characterization, while they're there to support him.
  • Your Size May Vary: Not them, but their machines can vary in size depending on the scene due to being SD gundams in matches with 1/144 scale normal gundams. Very noticable when they combine into the Snibal-Drago-Gira, as the thing can be kaiju sized at times even though it's composed of the same 3 SD gundams.

Voiced by: Romi Park (Japanese), Elizabeth Loennborn (English)
Main Gunpla: RGM-89 Jegan, XM-X1 Crossbone Gundam X1 Full Cloth

A minor character from Build Fighters who took to heart Aila Jyrkiainen's parting advice to play Gunpla Battle himself if he wanted a trophy so badly. He's currently enrolled at Granada Academy.


  • The Ace: He has apparently never lost a single Gunpla battle during his entire career in Europe, and is the current European Junior Gunpla champion.
  • Ace Custom: His Crossbone Gundam Full Cloth is so well-made that even Wilfrid acknowledges it as the single strongest Gunpla in the tournament in terms of raw specs, having top-grade speed, firepower, and durability. It was custom built by Lucas, giving it a fully functional Core Fighter to use should the Crossbone itself be somewhat immobilized even though the feature was left out in the High Grade edition. It's also a Walking Armory with a wide array of weapons options, including upgraded versions of the Crossbone's Peacock Smasher and Mega Machine Cannons. This ends up being semi-deconstructed as it's such an Ace Custom that it's the Gunpla equivalent of a gas guzzler, requiring Lucas to use his teammates as stealth recharge stations instead of fighting together.
  • Ascended Extra: Lucas is the grandson of the sponsor of Aila Jyrkiainen's Team Nemesis in Build Fighters. Despite having about 2 lines in the first series, he appears as one of the rivals at the national tournament in Try.
  • Big Bad: Though he's certainly not a villain, the series wastes no time in setting him up as the closest thing that it will probably have to an actual Big Bad.
    • Big Bad Wannabe: However, he ultimately loses in his match against Team Celestial Sphere in the semifinals after they figure out his secret.
  • Call-Back:
    • When asked to demonstrate his skills with any Gunpla at Granada Academy, he chooses a Jegan, to mirror Aila's demonstration of skill years earlier when she joined Team Nemesis.
      Lucas: Let's say its just a childish sentiment.
    • His necklace has the same design as the flower patch Aila had on her hat in Build Fighters.
  • Combat Pragmatist: Uses the environment to his advantage, which is necessary because his Gunpla burns through particles at an incredible rate and he needs time to recharge.. Exemplified when he uses the hole that Wilfrid made to hide his Core Fighter in to ambush Shia.
  • Cool, but Inefficient: The Crossbone's raw specs are so ridiculous that it can effectively take on all of Celestial Sphere at once, prompting Wilfrid to wonder how it's able to maintain such high performance for so long. It turns out that the Crossbone's overwhelming performance does drain its Plavsky Particle reserves at an incredible rate, forcing Lucas to resupply with his teammates' reserve energy.
  • The Dreaded: He's the only opponent that the Gunpla Academy seems truly worried about. Even more so after he totally demolished Team White Wolf. After the fact, Wilfrid Kijima acknowledges his Gunpla as the most powerful one in the tournament.
  • Exact Words:
    • Alia told him "If you want to win at Gunpla Battle, play it yourself". He took it to mean become a One-Man Army, refusing to let other people to play with him.
    • Averted, when in the battle against Gunpla Academy, he was in charge of choosing his team members and strategy. Though the strategy revolves around him at the center and those team members mainly acted as fuel stations, he by no means negates their importance. All leading up to defending them to the coach that the loss was due to his inexperience, not theirs.
  • Graceful Loser: When defeated by the Gunpla Academy, he congratulates them and smiles.
  • In-Series Nickname: "Lucas Nemesis" is unsurprisingly a moniker. His real name is Lucas Kankaansyrjä.
  • Lightning Bruiser: His Crossbone X-1 Full Cloth is enormously powerful, with incredibly high power, speed, and defense. Its so powerful that people wonder just how it can fight for so long and not be drained of plavsky particles. Its actually somewhat of a Glass Cannon with very limited endurance. It burns through particles at an incredible rate and relies on his teammates to act as moving particle storage tanks to refill it mid-battle.
  • Names to Run Away from Really Fast: Lucas Nemesis, as in the goddess of revenge in Classical Mythology or your worst enemy. Subverted in that he's actually a fairly upstanding and mellow guy, but he's a force to be reckoned with on the battlefield.
  • Space Pirates: He uses the Crossbone Gundam X-1 Kai Kai, a suit created by an army of Space Pirates in Mobile Suit Crossbone Gundam.
  • Took a Level in Badass: One of the biggest ones in the series. He went from a rich kid bit character who wanted a trophy won for him for his birthday to the European Junior Gunpla champion.
  • Took a Level in Kindness: A minor example, but he went from a Bratty Half-Pint who wanted the most prestigious award of the Gunpla Battle won for him as a birthday present to an Ace Pilot with a real sense of dignity.

Voiced by: Aya Endo (Japanese), Jessica De Borja (English)
Main Gunpla: KUMA-02/F Bearguy F (Family), KUMA-02/P Bearguy P

Sekai's older sister. She works part-time as a model for a fashion magazine, but becomes interested in Gunpla herself after her little brother becomes involved with Fumina's team.


  • Badass Adorable: While she hasn't devoted herself to it like Sekai has, she has been trained in the Jigen Haoh Ryu style of martial arts. Look at Mamagguy and Puchigguy holding hands. Look at Puchigguy using Jigen Haoh to kick ass.
  • Bears Are Bad News:
    • Just like its predecessor, Bearguy F is capable in combat as well. Moreso the Petit Beargguy on its back, which Mirai can also control as a back-up unit.
    • Then there's the Bearguy Pretty from Island Wars which cripples a man-sized Psyco Gundam Mk.II allowing team Try Fighters to finish it off.
  • Beary Friendly: All her Gunplas (the Bearguy F and Bearguy Pretty) look like a cute teddy bears with an even cuter teddy bear on their backs.
  • Calling Your Attacks: Does this in episode 10 when she's forced to call on her Jigen Haoh training.
  • Cool Big Sis: Is very supportive of her little brother Sekai's martial arts and his growing interest in Gunpla Battle, asking Fumina to look after him.
  • Cute Machines: The Acguy mobile suit was already considered somewhat adorable by fans. Adding teddy bear motifs just makes the robot cuter. And then the Beargguy F carries an even smaller Beargguy on its back.
  • Cuteness Proximity: She squeed when Yuuma suggested a Bearguy as her model
  • Date Peepers: Spies on her own brother during his "date" with Fumina.note 
  • Even the Girls Want Her:
    • The boys aren't the only ones captivated by her beauty when she walks into Sekai's classroom to give him his lunch.
    • At the national tournament's opening ceremony, a number of female attendees are also overcome by Mirai's "loveliness".
  • Gaussian Girl: All the time, courtesy of her many admirers.
  • Groin Attack: When she uses the Soten Guren-ken in episode 10, it becomes this due to the small stature of her Petite Beargguy.
  • Head-Turning Beauty: Her entrance to any given scene is generally accompanied by the gentle thuds of the male cast's jaws as they hit the floor.
  • Hot-Blooded: Becomes this when she's forced to call up on her old Jigen Haoh training.
  • Jumped at the Call: When all the build fighters elect to confront the overloading crystal in Island Wars, she doesn't hesitate to join in.
  • Large Ham: When she's caught up in battle and using Jigen Haoh.
    Mirai: I can feel it from your fist. Your evil feelings. I can feel your mean spirit!
  • Love Bubbles: Where she goes, these are guaranteed to follow. Episode 15 doubles as a funny Shout-Out to the Trans-Am Burst.
  • Oblivious to Love: She doesn't seem to notice Yuuma's huge crush on her.
  • Promoted to Parent: With their parents oddly absent, Mirai also acts as a mom to Sekai.
  • School Idol: She is implied to be the most popular girl in school, with some students having already seen her as a model in magazines. And after being chosen to step up as the National Tournament's image model, she's graduated into full Teen Idol status.
  • "Shaggy Dog" Story: Episode 10 was this for her - gets shanghai'd into a race, beats the jerk who would have made her go on a date with him if he won and makes it to the finish line only to have the Petitegguy trip on a rock and allow a Zaku I to win. However the winner of the race allowed Mirai to become the image model owing to pregnancy issues, so it worked out in the end.
  • Shipper on Deck: She keeps trying to trying to hook up Sekai and Fumina, and constantly spies on them whenever they end up alone together.
  • Shoryuken: Soten Guren-Ken. Very effective when your gunpla is small enough to use it as a Groin Attack.
  • Squee: During Episode 10, when Yuuma suggested a Beargguy kit as base for her personal Gunpla.
  • Stealth Pun: Now that she's landed the job as the image model for the tournament, she's literally a Gunpla Model.
  • Women Are Wiser: She's much more level-headed than her little brother and often has to pick up the slack, but obviously cares about him a lot.

Main Gunpla: GSX-401FW Stargazer, Maryu Kenshi Zero Gundam, PPMS-18E Kämpfer Amazing, Kurenai Amazing Musha

A female Gunpla player that unknowingly inspired Fumina's interest in Gunpla Battle. She's also the first woman shown to have inherited the Kawaguchi name.


  • Action Girl: She's a champion level Gunpla Battle player.
  • Badass Adorable: She seems to prefer the SD line of Gunpla models. She's still more than able to kick the asses of pretty much everyone not named Meijin Kawaguchi III (she even takes on all of Sekai's love interests at once in the finale).
  • But for Me, It Was Tuesday: A non-villainous variant. She doesn't remember the event that inspired Fumina to enter Gunpla Battle.
  • Cool Shades: Again, as befitting the Kawaguchi name.
  • Distaff Counterpart: She's the first woman to inherit the Kawaguchi name, and seeks to find worthy female successors for it.
  • Fashionable Asymmetry: Wears jeans that are legless on the left leg.
  • Large Ham: It comes with the territory of being a Kawaguchi, and she's every bit as hammy as Meijin.
  • Mysterious Waif: She is first seen with Tatsuya/Meijin Kawaguchi III in civilian wear.
  • Mythology Gag: Her character design is identical to Lili from Bandai-Namco's Tekken 5.
  • Navel Window: Her top split open above her pants to show her navel.
  • Only Known by Their Nickname: As she herself states, she's looking for her successor, implying that "Lady" is not actually her name, the same as "Meijin" not being the actual first name of the male inheritors of the Kawaguchi name.
    • Episode 3 of Gundam Build Metaverse confirms that Lady Kawaguchi is a title just like Meijin Kawaguchi as Maria Utrutsuki becomes Lady Kawaguchi VII, similar to how Tatsuya is Meijin Kawaguchi III.
  • Passing the Torch: Her main goal it seems is to find a worthy successor, with her current candidates being Shia and Fumina.

Main Gunpla: Scramble Gundam, Petitgguy (Purple)

A young girl who is the cause of the Island Wars OVA events. She is revealed to be Reiji and Aila's daughter.


  • Big Eater: She has a big appetite as she ate multiple bowls of curry. Runs in the family considering who her parents are.
  • Disappears into Light: Much like how her father left for Arian at the end of the original Build Fighters series, the girl leaves Earth with her Arista Gem.
  • Hereditary Hairstyle: The girl's hairstyle is identical to that of her mother.
  • No Name Given: While she appears in the Island Wars OVA, her name is yet to be revealed. (The Scramble Gundam manual likewise identifies her simply as "Mysterious Girl".) Though it can be assumed her last name is some combo of Jyrkiäinen-Asuna.
  • Shared Family Quirks: The girl shares her father's outgoing personality and his curiosity about Gunpla and life on Earth. She also shares her mother's butterfly Animal Motif as well as both her parents' love of food.
  • Spin-Offspring: It turns out that the girl is none other than Aila and Reiji's daughter.
  • Strong Family Resemblance: She has much of her mother's features (especially her eyes and hair), albeit with her father's skin tone and smile.
  • The Stinger: After the credits, she thanks her new friends for helping her make her own Gunpla, waves goodbye, and vanishes in a familiar flash of light. The next scene then shows her running across a field of flowers to her mother, Aila.
  • Unwitting Instigator of Doom: Her wish to have a Gunpla of her own jumpstarted the OVA's events.
  • Walking Spoiler: Finding out who her parents are before watching the OVA spoils its biggest twist. It also spoils the outcome of a major storyline in the original Build Fighters series.

Returning Characters from Gundam Build Fighters

Voiced by: Masashi Hirose (Episodes 1-4), Katsuhisa Houki (Episode 5 onward)
Main Gunpla: MS-07R-35 Gouf R35, MS-09R-35 Dom R35

Coach of the Gunpla Battle club at Seiho Academy.

For tropes applying to Mr. Ral in the original show, look here.


  • Blatant Lies: Apparently he's 35, despite being 35 in the original show a whopping 7 years ago.
  • Continuity Nod: His butt still gets itchy during Ship Tease.
  • Famed In-Story: "The Blue Giant", likely well known for both fighting in early world tournaments, but also for his involvement in the A Baoa Qu battle at the 7th championships.
  • Red Oni, Blue Oni: During the final episode, plays the Blue Oni to the Meijin's Red Oni, trying to convince the latter to not join into the Gunpla free-for-all and simply let the battle play out on its own.
  • Serious Business: Being a Shipper on Deck, of all things. During the massive battle royale in the last episode, he challenges Meijin Kawaguchi to prevent him from interfering with the massive brawl between Fumina, Shia, and Gyanko over Sekai.

The 3rd holder of the name Meijin Kawaguchi. Desides to watch the Tokyo Regional Qualifiers after he hears that Mr. Ral is coaching one of the teams there.

For tropes applying to Tatsuya Yuuki in the original show, look here.


  • The Ace: World-famous, good looking, an incredible Gunpla Fighter and Builder, and an inspiration to pretty much every Gunpla Fighter ever.
  • Ace Custom: Like any world-class Gunpla Fighter, Tatsuya has a whole line of personalized Gunpla customized to his specifications. They all have "Amazing" added onto their name to reflect this and are painted red.
  • All Your Powers Combined: His Amazing Full Amazing Strike Freedom features equipment from pretty much every gunpla he'd used up to that point, including the Fin Funnels and beam sabers from Hi-v Gundam Vrabe, the missle launchers and long canon of Zaku Amazing, 6 weapon binders from Kämpfer Amazing, the GN Sword of Gundam Amazing Exia and the booster arms of Amazing Z'Gok, on top of Amazing Strike Freedom's railguns and DRAGOON shields.
  • Berserk Button: He hates unsportsmanlike behavior. This is why he intervenes in the battle between Try Fighters and Saga, who was showboating and being deliberately cruel. Allan had to shut the entire arena down to keep Tatsuya from wrecking Adou's Gunpla. He even tells off Allan for not reigning in Adou.
  • Big Damn Heroes: Comes to Team Try Fighters' aid in their match against Adou.
  • Big Entrance: When he intervenes in the battle between the Try Fighters and Adou, a hole opens up in the clouds as light shines upon a wilted flower, which is then rejuvenated as the Gundam Amazing Red Warrior descends from the sky.
  • Cool Bike: Has a sleek looking red motorcycle, which probably runs three times faster.
  • Cool Shades: As the Meijin, now wears a different pair to the one he wore in Build Fighters.
  • Everyone Has Standards: He actively preaches for gunpla builders to make anything with their kits, but acknowledges that there are basic rules to follow. As such, he disqualifies Minato's well-crafted Meijin Cup Open Circuit entry because he built a kit of Fumina without her permission.
  • Hot-Blooded: As much as ever. Even just watching a good Gunpla match can get him all worked up.
  • Improbable Aiming Skills: Tatsuya can completely nullify oncoming beam fire by matching it with his own after his opponent had already fired at him. Onlookers are stunned at his pinpoint accuracy.
  • Kinetic Weapons Are Just Better: While he does carry multiple beam rifles on his Gundam Amazing Red Warrior, he gets a surprising amount of mileage out of his Hyper Bazooka, Vulcan Guns, and Missile Pods. His beam rifle is also equipped with a solid bayonet instead of the Beam Saber used by the Gundam Fenice, effortlessly cleaving through individual GN Fangs and matching a combined barrage from them.
  • Large Ham: Comes with the hot blood:
    Tatsuya: It's the radiance of human and machine as one! RAGE ON, GUNPLA!
  • Legendary in the Sequel: He's now a three time consecutive World Champion and was inducted into the Gunpla Hall of Fame. Because of this fame, Allan shuts down the fight between Tatsuya and Adou to prevent Tatsuya from wrecking Adou's Gunpla before the tournament.
  • Master of All: Yuuma notes that the Red Warrior has no real deficiencies, being top-grade in firepower, maneuverability, and speed while maintaining a respectable amount of armor. Tatsuya himself is a world-class Gunpla Builder as well as a legendary Gunpla Fighter.
  • Meaningful Name: The kit for the Amazing Red Warrior contains stickers with the initials "SK" (as seen here). These are indicative of his status as the Third MeijinClarification
  • Red Is Heroic: He loves the color red and he espouses all over Gunpla's best aspects: its artistry, competitiveness, and the love of the sport.
  • Red Oni, Blue Oni: During the final episode, plays the Red Oni to Mr. Ral's Blue Oni, bursting into the Gunpla free-for-all since he can't resist joining into the fight while Mr. Ral tries to convince him to let it play out without him.
  • Sunglasses at Night: He wears them under his motorcycle helmet.
  • Walking Armory: As with his previous Gunpla, Tatsuya's Red Warrior carries a multitude of weapons.
  • Warrior Therapist: Plays this role to Yuuma after the latter goes into a Heroic BSOD from losing to Adou a second time.
  • What the Hell, Hero?: When Minato protests not winning the Meijin Cup Open Circuit, Tatsuya points out that, yes, Gunpla is freedom, but there are rules you have to follow and he didn't follow a basic one: asking for Fumina's permission in using her likeness as a Gunpla.

    China Kousaka 
Voiced by: Yui Ishikawa

Yuuma's older sister, currently attending art school in Paris. Originally only been seen in the Six Years Later promotional short for Try as well as a flashback sequence, she finally makes an appearance in episode 19, delivering spare parts for the Build Burning Gundam to Yuuma.

For tropes applying to China Kousaka in the original show, look here.


  • Cool Big Sis: Towads her little brother Yuuma.
  • Costume Inertia: Played with, while the clothes she's wearing are clearly different, she still uses the same pink and white colors as she did 7 years ago.
  • Courier: Her appearance in episode 18 basically boils down to this. She has to meet Yuuma in the airport as soon as she lands to deliver the spare parts for the Build Burning Gundam as she has to catch the next plane back to France since she's actually in the middle of an exhibition for her art.
  • Hairstyle Inertia: Slightly longer, but it's still the same style she wore 7 years ago.

    Sei Iori 
Voiced by: Mikako Komatsu
Main Gunpla: BG-011B Build Burning Gundam

Protagonist of the original show and the current reigning Gunpla Battle World Champion. Currently touring around Europe to help promote Gunpla. Also responsible for building Sekai's Build Burning Gundam. So far has only been heard talking to China in the Six Years Later promotional short for Try.

For tropes applying to Sei in the original show, look here.


  • The Ghost: Only his voice is heard in the Six Years Later promotional short. We get a glimpse of him as Episode 24 ends, with Yuuma passing on a message that he forgot to deliver; he wants to fight Sekai someday.
  • Heartbroken Badass: Six years on he's still waiting for Reiji to return and fulfill their promise, which is why he built the Build Burning Gundam in the first place. The heartbroken part comes from the fact that he eventually decided to seal it away alongside his memories of "his precious best friend". The GM's Counterattack midquel OVA shows that this trope is averted: Reiji DID manage to return one more time via Aila's Arista, saving the gang's skins in the nick of time while being able to duel Sei one more time, using the Build Burning's predecessor, Star Burning Gundam. The Build Burning that Sei leaves in the trophy turns out to be a memento of that fight, rather than a painful reminder of Reiji's absence.
  • Legendary in the Sequel: Any gunpla player and modeler worth his salt has heard of Sei, who has remained a big shot Gunpla battler and model builder since his victory with Reiji 7 years ago. Case in point, his Build Burning Gundam stands above all other current models in the series in performance, despite just being a prototype for the 11th Gunpla Championship.
  • Sinister Silhouettes: The second opening has a shot of him walking through the Seihou Academy Gunpla Battle clubroom, with only his shadow visible.
  • Take Up My Sword:
    • He leaves one of his "ultimate" Gunpla, Build Burning Gundam, hidden in the room of Seihou Academy's Gunpla Battle Club, only for the protagonists to discover it years later.
    • In episode 18, he has China deliver a message to Sekai that the Build Burning Gundam is now his.
  • Ultimate Blacksmith: Treated as such. The RG system he created for his Star Build Strike Gundam is still legendary to the present day. Notably, the Absorb System was worth picking out and enhancing to Team SD-R, as well.

    Allan Adams

Voiced by: Subaru Kimura

Former Chief Engineer at PPSE who served as the 3rd Meijin Kawaguchi's right-hand man. After PPSE was disbanded, he revived the Gunpla Academy, and now serves as its coach.

For tropes applying to Allan Adams in the original show, look here.


  • Insistent Terminology: He constantly asks everyone to call him coach while he's working. Despite that, everyone still calls him Allan (Yuuki), Uncle (Wilfrid & Shia) or Chief (his former PPSE subordinates who're now working for the Gunpla Academy).
  • Meaningful Background Event: You can spot him on stage in Episode 1, when Tatsuya Yuuki presents Yuuma the Gran Prix award at the Gunpla modeling competition.
  • Passing the Torch: He's become a coach for a new generation of Gunpla battlers.

Voiced by: Shinnosuke Tachibana

The former American Gunpla Battle Champion, now Chief Engineer at Yajima Engineering, having rediscovered Plavsky particles after the 7th Gunpla Battle Championship. Nils' department is responsible for designing and building the newest generation of Gunpla Battle terminals.

For tropes applying to Nils Nielsen in the original show, look here.


  • Happily Married: To Caroline.
  • Labcoat of Science and Medicine: Wears a labcoat to reflect his current work as a Plavsky Particle researcher.
  • Retired Badass: He's now officially retired from gunpla battle, since, as he explains to Ral, he knows Plavsky Particle manipulation in and out, and knows the Gunpla Battle systems like the back of his hand, so he'd have an overwhelmingly unfair advantage.
  • Took the Wife's Name: Upon marrying Caroline, he takes up her surname. This is more of a Japanese cultural thing. He was marrying up, and typically someone marrying 'up' in social structure takes the family name of the one of higher social strata, in order to carry on the family name.

    Susumu Sazaki 

Kaoruko Sazaki's older brother. In the seven-year interim, his building and battling skills have improved to the same league as Sei.

For tropes applying to Susumu Sazaki in the original show, look here.


  • The Ghost: He's dosn't to appear, only being mentioned by his younger sister and past opponents.
  • Took a Level in Badass: It's revealed that he made the Best 16 in the 10th World Tournament.
  • Ultimate Blacksmith: His Gyan shields are praised for their quality, and Kaoruko makes two of them the centerpieces of her R-Gyagya.

    Kirara / Mihoshi 

A Gunpla idol who has since shot up into Hollywood stardom.

For tropes applying to Kirara/Mihoshi in the original show, look here.


  • The Cameo: Gets mentioned by Mirai's manager.
  • Rags to Riches: When we first saw Kirara back in Build Fighters, she was an idol on her last legs. She ends up turning her time as a Gunpla Battler and Gunpla Idol to regain her stardom, ditch her "Kirara" identity and make a name for herself as an actress.

     Rainer Cziommer 

A Gunpla Fighter from Germany who had issues with Fellini. Returns as an analyst for the All-Japan Under 19 tournament.

For tropes applying to Cziommer in the original show, look here.


  • The Cameo: Is mentioned as an analyst for the All-Japan Under 19
  • The Unseen: Though he is mentioned, we don't get to see him on TV as the camera cuts away right before his segment.
  • The Voiceless: Similar to the above.

    Aila Jyrkiäinen (Spoilers) 
https://static.tvtropes.org/pmwiki/pub/images/aila_8.jpg

The former represenative of Finland now a young adult. Aila shows up at the end of the Island Wars OVA and is revealed to be the mother of the "Mysterious Girl".

For tropes applying to Aila in the original show, look here.


  • Babies Ever After: This is the big reveal at the end of the Island Wars OVA. The nameless girl whose Arista crystal caused the disturbance is her and Reiji's daughter.
  • The Cameo: Only shows up in the final minute of Island Wars.
  • Earn Your Happy Ending: Given that she's endured a horrific childhood, it was already heartwarming that she was able to escape Team Nemesis and come along with Reiji via her Arista at the end of the original show. Island Wars one-ups this by revealing that she and Reiji are not only married, but also have a daughter together in Arian.
  • Happily Married: To Reiji.
  • Rags to Royalty: Aila grew up in Finland as an orphan and was abused and exploited by Nine. As of the Island Wars OVA, however, it is clearly alluded that Aila is now married to Reiji (Arian's crown prince), and she is seen at the end with her and Reiji's daughter.
  • Teen Pregnancy: Implied. Unless time passes differently in Arian, and given that "Mysterious Girl" can't be any younger than about 5-6 years old, means Aila had to have given birth before she even reached full adulthood. This would explain her absence from the GM’s Counterattack OVA, where she was likely too busy taking care of her and Reiji’s baby to take part in the events of the story.
