Main Characters (Ryuko Matoi) | Elite Four | Mankanshoku Family | Club Presidents and Other Students | Nudist Beach | Kiryuin Conglomerate
Honnouji Academy students who run the school clubs and work directly under the Elite Four as henchmen. Only they are permitted to wear Two-Star Goku Uniforms that grant them superpowers greater than One-Stars' simple Status Buffs, but nowhere near as powerful as Three-Stars.
- The Assimilator: Aside from Iori, they are at one point absorbed by COVERS until they are rescued in episode 22.
- Back for the Finale: After being rescued from the COVERS which absorbed them, every single last one of them shows up in time for episode 23 in order to take back Honnouji Academy.
- The Bus Came Back: They reappear in episode 22 after being rescued from COVERS. The first president that joins the battle is Fight Club President Mako Mankanshoku.
- Clothing Damage: All of their uniforms get destroyed when Ryuko defeats them.
- Custom Uniform: Like the Elite Four, their Goku Uniforms are made to stand out among their club members. Most notably, their star crests and weapons glow a luminescent red.
- Degraded Boss: Club Presidents become this by episode 5, and are taken out by Ryuko in episode 7 without even 30 seconds of screentime. Hell, they're lucky if they have more than four seconds of screentime at that point.
- Elite Mooks: While ordinary One-Star students can be taken out by Ryuko with ease, these guys can give her a run for her money on a bad day.
- Monster of the Week: Played straight initially then subverted. For the first four episodes, they are treated as a real threat who can give Ryuko a run for her money. By episode 5, she can one-shot them in seconds.
- Put on a Bus: Due to their Monster of the Week status, they disappear from the story once Ryuko defeats them. Except Iori, who is the only one she doesn't fight.
- Quirky Miniboss Squad: With the exception of Iori and Mako, they all answer to the real bosses of the school.
- Spikes of Villainy: Like the Elite Four, a good many of the club presidents' uniforms have these features.

The Sewing Club President and nephew of Satsuki's butler, Soroi. He oversees the research and development of the Goku Uniforms.
- Adjusting Your Glasses: By the bridge. Double the badass level when he performs this alongside Chairman Inumuta.
- Anti-Magic: He's developed a tranquilizing coagulant that works to shut down goku uniforms temporarily. He uses it in Episode 16 to free Satsuki from Junketsu, and later tries to use it to halt the primordial life fiber, but it manages to break free.
- Badass Boast: When Aikuro asks if Shiro's able to mass produce Goku Uniforms all by himself, he confirms as much before activating his Three-Star Uniform:Iori: "I'm all the help I need."
- Bishōnen: He is short, slender, and has long, wavy blonde hair.
- The Blacksmith: As the head of the sewing club in a world where clothing is weaponized, he's basically this.
- Childhood Friends: According to the drama CD, he's been friends with Satsuki since her father faked his death, when his uncle brought him over to play with her, so she wouldn't be alone.
- Cool Mask: Wears a translucent orange gas mask, presumably to protect himself from some dangerous particulate produced by Life Fibers. It becomes translucent green when activating his Three-Star Uniform.
- Dude Looks Like a Lady: He could easily pass for a flat-chested girl.
- Forehead of Doom: He has a large forehead.
- Gadgeteer Genius: He is the one who designs and constructs the Goku Uniforms. Might share this position with Inumuta who specializes in gathering and analysis of battle data which are later used to improve the uniforms. Iori was also the one who built the Vacuum Fist used by Gamagoori to save the COVERS victims.
- Gas Mask, Longcoat: His overall look, with his uniform length extending far beyond his height. The mask itself becomes exaggerated upon activating his Goku Uniform.
- I Am Not Left-Handed: It turns out that his uniform is a Three-Star. The third star was hidden by his folded collar.
- Implausible Hair Color: Despite being full Japanese, Iori has blond hair.
- Labcoat of Science and Medicine: The first sign that Iori isn't just your run-of-the-mill tailor. It's actually his Goku Uniform.
- Large Ham: Not normally, but when he activates his uniform he doesn't say its name, he screams it at the top of his lungs.
- Long-Haired Pretty Boy: He has long, wavy blonde hair in a loose ponytail down to his mid-back.
- Non-Action Guy: Even though he's a Two-Star actually Three-Star student, he is literally the only plot-relevant student who doesn't actively participate in combat. He does own a Three-Star Uniform which could presumably be used for combat, but his usefulness behind the front lines is likely superior to sending him fighting.
- Odd Friendship: Unlike the other club presidents, he speaks with the Elite Four on equal terms. It turns out to be because he's the nephew of Soroi, Satsuki's butler, and he's also part of Satsuki's conspiracy to kill Ragyo and destroy REVOCS/COVERS.
- Perpetual Frowner: Even more so than Satsuki. He never smiles and sports an expression of eternal annoyance at the world around him. This changes in at the end.
- Red and Black and Evil All Over: His activated Goku Uniform is decorated in these colors, although by the time he shows it, he's already working with Nudist Beach.
- Sixth Ranger: While not part of Satsuki's Elite Four, he's still associated with them in the manufacture of Goku Uniforms and is the only non-Elite Four student in on Satsuki's rebellion, as well as having the privilege of wearing a Three-Star Uniform. As such, he's implied to be at the same level as the Elite Four in all but name.
- Spider Limbs: His activated Goku Uniform features four additional appendages to assist his sewing.
- Stoic Spectacles: He's a Perpetual Frowner who won't even smile when thanking someone for saving his life.
- Theme Naming: The second character of his surname means "to knit", while the first character of his given name means "thread".
- Transformation Sequence: He gets a brief one when changing into his Three-Star Uniform.
- The Unfought: Despite being a member of Satsuki's inner circle and a Three-Star student, he's never fought by Ryuko. Considering that he's a Non-Action Guy, this is a given.
- Utility Magic: While most Goku uniforms are designed for combat, Iori's three-star uniform — Tailor's Regalia — is designed to create Goku uniforms at an accelerated pace.

The Boxing Club Captain. His Two-Star Goku Uniform gives his boxing gloves the strength of steel.
- Badass Longcoat: Worn alongside his boxing attire.
- Bald of Awesome: His appearance beneath that helmet.
- Boxing Battler: His entire gimmick.
- Calling Your Attacks: Calls out his punches as if he were the ringside commentator of his own match:
- Combat Tentacles: His left glove launches a stream of punches so rapid that it essentially functions as this.
- Cool Helmet: Always wears protective headgear.
- Extremity Extremist: Subverted; he's more than happy to use kicks in a fight.
- The Gloves Come Off: When he's done playing around, he removes his right glove, revealing a huge slab of steel that resembles a meat tenderizer.
- Hypocrite: Accuses Ryuko of mocking boxing by wearing a Stripperiffic uniform to distract him in battle. His defending the sacrosanct spirit of the sport is soon revealed to be a complete bull when it turns out his boxing glove is there to hide his metal Power Fist.
- Large Ham: He gets a bit too excited when detailing the powers of his "ATHLETICISM-AUGMENTING TWO-STAR GOKU UNIFORM!!!"
- Megaton Punch: He has this gloves or no gloves.
- Pint-Sized Powerhouse: He's only slightly larger than Ryuko, yet he delivers a complete and utter smackdown on her.
- Power Fist: His Two-Star uniform gives him this power.
- Punny Name: In Japanese name order, "Fukuroda Takaharu" sounds similar to "fukurodataki", which means "to beat up by ganging up".
- Signature Move: Tekken Funsai (lit. "Iron Fist Smash").
- Spam Attack: His left jab launches a stream of steel boxing gloves at his opponent.
- This Is a Drill: His corkscrew punch attack makes his right hand glove spin. The effect is enough that it rips the cloak that Ryuko was wearing to cover up her uniform.
- The Worf Barrage: His final attack against Ryuko is a full-power punch without his glove on... and it doesn't even scratch her.
- Would Hit a Girl: A particularly egregious case as the very first thing he does is deck Ryuko with a boxing glove twice the size as her entire body.
- Wake-Up Call Boss: He's the first real opponent Ryuko faces that isn't a Red Shirt and lays quite the beatdown on her before she gets Senketsu and returns the favor.

The Tennis Club Captain. Her Two-Star Goku uniform comes with a menacingly large tennis racket.
- Between My Legs: The audience's first look at her Two-Star uniform, with her skirt packed with tennis balls.
- Dark Action Girl: Omiko is the first female club president that Ryuko faces, and an arrogant brute if there ever was one.
- Fangs Are Evil: She bares her fangs a lot and only when she wants to kick some ass.
- Girlish Pigtails: She wears her hair in high pigtails. Most likely a tribute to Gamia from Mazinger Z.
- Goggles Do Something Unusual: Has multiples lenses, one of which is telescopic.
- Implausible Hair Color: Despite being full Japanese, Omiko has blond hair.
- Improbable Weapon User: Uses a giant steel spiked tennis racket in combat.
- Light Is Not Good: She has blond hair, but she is also one of the villains in the series.
- Making a Spectacle of Yourself: She wears a huge one-sided, interchangeable aiming lens for precise hits.
- Minidress of Power: Her Goku Uniform, befitting a tennis player, and with a skirt made of balls no less.
- More Teeth than the Osmond Family: Those shark teeth of hers sure do seem evocative of Viral from Tengen Toppa Gurren Lagann.
- Named After Somebody Famous: Her name sounds similar to the famous Japanese tennis star, Kimiko Date-Krumm.
- The Only One: Omiko muses that, on the tennis court, the only person one can rely on is one's self.
- Sadist Teacher: Club Captain in this case as she has the entire tennis team pelt Mako with tennis balls as punishment for not attending team practice. What's more is she knows Mako was being held hostage just to lure out Ryuko, but she still counts it against her because it happened without her permission.
- Slasher Smile: Her default expression, given her pointy teeth.
- Spam Attack: Her 110 Million Serve, which fires many, many tennis balls at the target's face.
Voiced by: Marina Inoue (Japanese), Dorothy Elias Fahn (English)
Ryuko and Mako's classmate, an injured No-Star student who they help on No-Late Day. In truth, she is the Head of Trap Development for the Disciplinary Committee, who plots to steal Senketsu for her own ends.
- Ain't Too Proud to Beg: In episode 4, after Maiko tries to use Senketsu, she finds that she is unable to move, and once Ryuko sees this and starts gearing up to attack her, she immediately shifts her mood and tries begging for mercy. It doesn't work.
- Back for the Finale: Surprisingly, she can vaguely be made out in the background alongside a few club presidents.
- Badass Driver: She can drive a turret-mounted armored bus like nobody's business.
- Badass Normal: For a No-Star student, she can be awesome.
- Better to Die than Be Killed: Hilariously subverted; she throws herself off a highly elevated rolling platform after setting off one last trap for Ryuko, claiming she'll at least die with her dignity as a member of the Disciplinary Committee intact, only to open a parachute at the last second.
- Big Bad Wannabe: She had a pretty solid plan to get Senketsu from Ryuko, which she actually succeeds in. Unfortunately for her, this is all she's able to accomplish, as Senketsu rejects her, which leads to Ryuko promptly kick her ass and is subsequently expelled from Honnouji Academy by Gamagoori.
- Bitch in Sheep's Clothing: Pretends to be a nice, modest girl to gain Ryuko's trust in order to steal Senketsu.
- Card-Carrying Villain: Once she stops her nice girl façade.
- The Chosen Wannabe: She puts on Senketsu and easily activates his power. However, just because she is shameless enough to master the skimpy power of Senketsu within seconds, that doesn't mean that Senketsu will let her use him for her personal gain.
- Contrived Clumsiness: Clumsily falls into Ryuko repeatedly while they're trying to get back to Honnouji Academy, constantly causing the Mankanshoku family to be Distracted by the Sexy and screwing up their attempts to give Ryuko her uniform. Yeah, that was exactly the plan.
- Custom Uniform: Subverted; despite being a club president, she's a No-Star like Mako. This is probably intended so that she can better blend in with the crowd since part of her role is to lure the students into her traps.
- Department of Redundancy Department: "CHIKARA-POWER!"note
- Determinator: Big time, even after she thrashed for talking big to Ryuko and her plans fall through, she still tries her hardest to get her expelled. And that's not getting into her willfully defying Gamagoori's word to get back at Ryuko alongside Fukuroda and Hakodate, an action that noticeably impresses Satsuki in the first Drama CD.
- Didn't See That Coming: Successfully manages to put on Senketsu, but fails to realize that the only one he'll ever let use him is Ryuko.
- Evil Is Hammy: As soon as she reveals her true nature, she really cuts loose.
- Evil Laugh: She has a very distinct Noblewoman's Laugh.
- False Friend: Acts as Ryuko's friend just so she can get her hands on Senketsu.
- Handicapped Badass: She does all this with her arm in a cast! Except the "handicapped" part is fake.
- I Will Only Slow You Down: In episode 4, Maiko tells this to Mako and Ryuko once Mako suggests to bring her with them since she broke her arm on the first No-Late Day trap. The pain ends up overwhelming her, and Ryuko brings her along anyway. She turns out to be a mole.
- Kick the Dog: Literally does this to Guts when he tries to return Senketsu to Ryuko.
- Laser-Guided Karma: Once she thinks she's gotten away after setting one final trap for Ryuko, Gamagoori promptly and justly expels her from Honnouji Academy.
- Manipulative Bitch: Her "injured schoolgirl" act has Ryuko and Mako totally fooled while she plots to steal Senketsu at the right moment.
- Master of Disguise: In the first Drama CD, she replaces Mako and manages to flawlessly fool Ryuko again just long enough to try for a second attempt.
- Meganekko: Of the bitchy, manipulative variety.
- The Millstone: On top of dragging Ryuko down, she accidentally pulls down her pants whenever Mako's family (carrying Senketsu) catches up with her, causing them to crash while distracted. It is later revealed that this was intentional.
- The Mole: Her job entails going undercover as an ordinary student and setting up traps based on their behavior.
- Noblewoman's Laugh: KYAHOHOHOHO!
- Red Eyes, Take Warning: It's the first tell-tale sign she's really no good.
- Red Herring: During her debut episode, she does her best to look like the second best friend to Ryuko and Mako, even reaching the school's gates and taking a commemorative BFFs photo. You just know the writer was toying around with this the moment said photo is destroyed.
- Revenge: Her main objective in the first Drama CD, alongside Fukuroda and Hakodate, after her humiliation from Ryuko.
- Scary Shiny Glasses: A staple of hers once she shows her true colors.
- Shameless Fanservice Girl: Lampshaded by Senketsu; she has absolutely no shame, which is why she can wear him so easily.
- Smug Snake: She thinks she could have overthrown Satsuki had her plan succeeded. One has to wonder where all this self-confidence comes from.
- The Starscream: After growing sick and tired of her job, she concocts a plan to overthrow Satsuki as Student Council President using Senketsu. Once her treachery is exposed, Gamagoori expels her for good.
- Theme Naming: "Mai" is a kind of linen robe.
- Trap Master: Helped build an entire amusement park of traps throughout the city.
- Wounded Gazelle Gambit: She fakes an arm injury to get Ryuko to take pity on her and help her.
Kusanosuke Yaguruma & Kusatao Uwabami
Voiced by: Ryo Naito (Yaguruma), Norihisa Mori (Uwabami) (Japanese)
The Terrace and Backyard General Managers of the Gardening Club, respectively.
- Cannon Fodder: Jakuzure only sends Uwabami out to test Ryuko and Tsumugu.
- Disproportionate Retribution: Yaguruma tries to kill Tsumugu because he trampled his club's flower beds.
- Gonk: Both of them have huge noses and buckteeth.
- Green Thumb: By adding water to the flower pot on his back, Yaguruma can grow giant Man-Eating Plants in seconds. Uwabami can presumably do the same, not that we get to see it.
- Improbable Weapon User: Their weapons are watering pots.
- Man-Eating Plant: Can grow these from the planter on their backs.
- Meaningful Name: The "kusa" character in both their names means "grass".
- Red Baron: "Squint-eyed" Kusatao; he's even listed in the credits as such.
- Revenge: Kusatao takes on Tsumugu to avenge Yaguruma.
- Serious Business: Their club's flower beds, considering Yaguruma tried to kill Tsumugu over them.
- Sinister Shades: Yaguruma (above) wears these.
- Stealth Clothes: Even though the handkerchiefs they wear on their heads can be commonly found amongst Japanese agricultural fashion to prevent sunburn and block excess sweat, it's hard not to notice them being insidious individuals.
- We Hardly Knew Ye: Yaguruma's introduction and defeat take place in the same scene. But that's nothing compared to Uwabami, who only gets one line and no fight scene before he's taken out.
- Acrofatic: Masuyo Watari. She has to be by default if an overweight student like her is The Tightrope Walking Club's president.
- Breath Weapon: Aizenbo Fuguhara, the Ping Pong Club President, can breathe fire by drinking gasoline.
- Body Horror: The nameless Biology Club President's two-star uniform removes all the skin on the left half of his body, making him resemble an anatomical mannequin. The one-star members of the same club have their brains exposed, and their faces lack skin or muscle on one side. Fortunately, they're blink and you'll miss it.
- Cannon Fodder: Like Uwabami, Jakuzure sends the presidents of the Rakugo and 100 Poems Clubs to gauge Ryuko and Tsumugu's abilities.
- Combat Tentacles: Kagesaburo Kagero, who uses Nanjing Lilies to this effect.
- Dance Battler: Maimu Okurahama, the Folk Dancing Club President.
- Degraded Boss: The last couple club presidents actually gave Ryuko quite a challenge. These guys? Taken out in a Ryuko-winning montage.
- Dishing Out Dirt: The power of the Three Touki Brothers of the Pottery, Arts, and Crafts Club, who can control clay.
- Drives Like Crazy: Ryosuke Todoroki of the Automotive Airsoft Club, whose Goku Uniform is also his car.
- Expy: Jack Naito seems to be one of Jackknife.
- Flaming Hair: Todoroki's hair is a glowing red flame, or at least resembles one.
- Flechette Storm: Jack Naito's attacks.
- Improbable Weapon User: Razor pillows, poetry cards, ping-pong balls, origami cranes, etc. Some of these guys have some weird arsenals.
- Knife Nut: Jack Naito, president of the Knife-Throwing Club.
- Meaningful Name: Each character in Todoroki's name contains the radical for "car".
- No Name Given: The Biology Club President is the only unnamed club president who gets any speaking lines.
- Paper Master: Tatamu Otte, the Origami Club President. Presumably.
- Stripperiffic: The only thing covering Aizenbo Fuguhara's breasts are a pair of ping pong paddles.
- Villainous Harlequin: Tightrope Walking Club President Masuyo Watari dresses like a clown.
- We Hardly Knew Ye: They're lucky to get even two lines of dialogue before Ryuko strips them. Hell, one of them doesn't even get to announce their name before getting taken out.
Voiced by: Nobuhiko Okamoto (Japanese), Johnny Yong Bosch (English)
A No-Star student and former member of the Newspaper Club, suspended from Honnouji Academy after trying to start an insurrection against Satsuki through the school paper.
- Amusing Injuries: His beatdowns from the Disciplinary Committee are quite comical.
- Badass Normal: He's a No-Star student, yet he's willing to face down hulking One-Stars if it means taking down the system.
- Chaste Hero: Played to ridiculous extremes when he nonchalantly emerges from a bathroom stall to speak to Mako in the girl's room. It's a subtle hint that he himself is actually a girl in disguise.
- Determinator: Even while held down and beaten to a pulp by a gang of brutish thugs, he fiercely refuses to stay down until he gets Ryuko's attention. It turns out it's because they couldn't really have hurt him anyway.
- Dissonant Serenity: He becomes quite serene and creepy moments before revealing his true identity.
- Foreshadowing: When he's introduced, the Boss Subtitles are black instead of red. Implying that it's not his real name at all. He also mentions Satsuki had banned him from school recently. Satsuki forbid him from entering the school grounds after Nui messed with her plans.
- Glamour Failure: The reason his hair covers his left eye is to hide Nui's trademark eyepatch.
- Hot-Blooded: He slams his cup down on the tray when having a meal with Ryuko and Mako, then goes on to pound the floor repeatedly, spilling everyone else's tea.
- Large Ham: Shinjiro does not speak, he SHOUTS.
- Marionette Master: Those thuggish One-Star students who keep trying to silence him are actually giant marionettes "he" controls using Life Fibers.
- Meaningful Name: "Shinjiro" sounds a lot like "shinjiru", the Japanese verb meaning "to trust". Ironically, it's to further emphasize Nui's deception of Mako and Ryuko.
- Peek-a-Bangs: His left eye is covered by his hair. It's to hide the fact that it's missing due to Glamour Failure.
- Suspiciously Specific Denial: One of the first lines out of his mouth is "I'm not a suspicious person".
- Voice of the Resistance: He uses his papers to put together his own resistance against the Student Council.
- Walking Spoiler: In case the blanked out entries didn't tip you off, he is really Nui in disguise.
- Wide-Eyed Idealist: He cherishes freedom of speech in a world oppressed by Satsuki, and is passionate in his belief that Ryuko can save their school, which has gotten him in trouble with the Student Council many times.
- Wounded Gazelle Gambit: His helpless fight against the Student Council is part of an elaborate gambit to get Ryuko to take pity on him and put Senketsu on again.
Voiced by: Chihiro Suzuki (Japanese), Sam Riegel (English)
A No-Star student who steals a one-star Goku uniform in the first episode.
- Bullying a Dragon: He gets so emboldened by the power of his stolen one-star Goku uniform that he tries to fight Gamagoori mano-a-mano. Unfortunately for him, not only is Gamagoori physically superior to him in every way without a Goku uniform, Gamagoori's is a three-star. Suzuki barely has time to realize his mistake before Gamagoori tears him to shreds.
- Conveniently Seated: He originally sat right next to Mako. Thanks to his death, that seat becomes open for Ryuko.
- Curb-Stomp Battle: Once Gamagoori stops messing with him.
- Dead Guy on Display: His body was strung up naked in one of the school's primary hallways with a sign warning other students of the dangers of trifling with the Student Council.
- Early Installment Weirdness: His brutal death at the hands of the Student Council demonstrates the tyrannical control they hold over the school, but doesn't really jive with the way they treat the student body for the rest of the series.
