Souji Mitsuka/Tail Red
Voiced by: Nobunaga Shimazaki (Souji), Sumire Uesaka (Tail Red, Sora) (Japanese), Austin Tindle (Souji), Bryn Apprill (Tail Red, Sora) (English)
- Age: 15Birthday: February 2 (Aquarius)Height: 164cm (146cm as Sora)Weight: 52kg (45kg as Sora)
- Attractive Bent-Gender:
- When Souji turns into Tail Red, he becomes a ridiculously adorable little girlshe's so cute that it prompts instant Cuteness Proximity from every human and a least half of Ultimaguil.
- SoraSouji actually genderbent into a girl of his ageis easily the most physically attractive of the Twintails, clearly blessed by his/her mother's genes.
- Badass Adorable: As Tail Red. Just look at her.
- BFS: His primary weapon, with Flaming Sword thrown in for good measure.Blade Release! GRAND BLAZER!
- Birds of a Feather: With Dragguildy, as he is truly devoted to Twintails unlike most of Ultimagil. It's to the point that they mutually express regret that their circumstances do not allow them to be friends, and consider each other Worthy Opponents pretty much from the get-go.
- Chaste Hero: As stated in his character profile, all the sexual desire expected from a boy his age has been channeled into a twintail fetish. Twoearle's blatant intent to get in his pants and Erina's masochism often go completely over his head. After Dark Grasper kisses him, he finds himself gradually actually becoming more interested in the female figure than the twintails that they wear, which briefly puts him through a non-super Gender Bender as his base form and his voluntary Super Gender-Bender weakening more and more with each fight until he learns to appreciate twintails again.
- Chick Magnet: Aika hopes to be a Victorious Childhood Friend, Twoearle fell in Love at First Sight, Erina approaches Twoearle-levels of depravity in her affection for Souji (on top of being pretty happy with her mom dubbing him her fiancée), Anko fell for Tail Red after being defeated, and it carried over into Souji, and so on. Not to mention that Tail Red is overwhelmingly popular with people of all the walks of life, if you catch our drift.
- Childhood Friends: With Aika.
- Combat Pragmatist: He doesn't exactly fight fair against Elemerians. This is at least half of the comedy of the series. An example would be: after a lot of explanation from Erina that they should fire the bazooka that they have towards Isuna, Souji just pulls the trigger with no fanfare leading to a Big "WHAT?!" from both Erina and Aika.
- Dual Wielding: Souji eventually figures out that if one ribbon means one sword, then Twintails means Dual Wielding.
- Everyone Knew Already: Most of Souji's circle had it figured out he was Tail Red for a long time. They just masked it by going with the flow: talking about Red when he was troubled and otherwise gushing about her when he wasn't.
- Eye Colour Change: From orange (civilian) to light purple (Tail Red).
- Fetish: Take a wild guess. His love for twintails is used against him when Foxguildy creates a doll of Tail Red and he is unable to destroy it because of its twintails.
- First Kiss: Souji (as Tail Red) gets his first kiss from Isuna who apparently captured her heart. This is after he blasted her with a bazooka.
- A God I Am Not: Dark Grasper points out that with the many worldwide fans Tail Red has, she might as well be a god. Tail Red dismisses that claim, and declares herself to be nothing more than a protector.
- Golden Super Mode: In true sentai fashion, Tail Red gains this form in the final battle against the Elemeras. Red's hair stays red though.
- Hair Antennae: Both as a civilian and Tail Red. The trait carries over into Sora.
- The Hero: The main protagonist of the series.
- Heroes Prefer Swords: He is The Hero (not just any hero) and uses a sword.
- Heroic BSoD: After the kiss from Isuna/Dark Grasper, he starts to not like twintails as much as he used to.
- I Am Not Left-Handed: Dragguildy disarms Tail Red of her sword, only for her to conjure up another one. She admits she had no idea if it would work.
- Invocation: RISER CHAIN!!! FALLER CHAIN!!!
- The Leader: Of the Twintail Warriors. He pulls the rest of the team together, and they wouldn't go too far (without killing each other) without Souji.
- Man, I Feel Like a Woman:
- Parodied when Aika and Twoearle assume Souji will do this as Tail Red, but the worst he does is fondle Tail Red's twintails.
- Subverted in episode 11 after Souji is transformed into a girl, he is too afraid to go to the toilet because of this.
- Only Sane Man: Despite his notorious twintail fetish, he ends up as this around one girl who normally fulfills this trope until her chest size is brought up, one girl who indicates every other minute that she wants to get in his pants and shamelessly lusts after little girls, one girl who is a huge masochist, and a Chuunibyou mother.
- Playing with Fire: His element.
- Pintsized Powerhouse: As Tail Red.
- Red Is Heroic: This work is making fun of Tokusatsu and all its tropes. According to Tokusatsu convention, the red one is the leader.
- School Swimsuit: As Tail Red.
- Serious Business: He takes Twintails very seriously. Good for him, because the universe does too.
- Signature Move: Grand Blazer.
- Significant Birth Date: His birthday, February 2, is Twintail Day in Japan.
- Skyward Scream: When he's starting to realize that he's turned his back to twintails and that he's realizing that a woman's lips are beautiful.
- Spell My Name with an "S": Solar Metca, or Sora Mituka, Souji's genderbent form. The light novels use the former transliteration.
- Super Gender-Bender: The Tail Bracelet turns him into a short and flat-chested redhead wearing long twintails (who suspiciously looks like Cuuko) whenever he transforms into Tail Red. He doesn't seem to mind though.
- At the end of Episode 10, he wakes up as a girl - and he's not in his Tail Red form. This one is an inversion, however; turning into a Distaff Counterpart of his normal self is a sign that something is not right with his Twintails attribute, and sure enough, for the period of time that Souji exists as Sora, turning into Tail Red actually depowers her, to the point that she becomes just as helpless as her appearance would suggest. It isn't until Souji gets his act together that the situation returns to normal.
- Super Mode: After overcoming a temporary slump and reaffirming and strengthening his love for Twintails, Tail Red manages to acquire one through Twoearle's barrettes. It seems to be based on a Stance System, switching between a Speed Blitz and overwhelming force. Notably, it's what allows Tail Red to defeat Arachneguildy. Before then, he was steamrolling the Twintails.
- Later novels show that Tail Red eventually gains two further upgrades: Fallraiser Chain, which offers the benefits of both Faller Chain and Riser Chain, and Ultimate Chain, which has so many insanely overpowered abilities that defining Tail Red as a Person of Mass Destruction would not be exaggeration.
- Took a Level in Badass: Acquires Riser Chain and Faller Chain during the battle against Arachneguildy, courtesy of Twoearle's Progress Barrettes.
- Unwanted Harem: Has the affections of Aika, Erina, Twoearle, and even Isuna. Even his mother admitted she'd support him all the way should he pursue a harem.
- Unwitting Instigator of Doom: Dark Grasper kissing Tail Red caused Souji to pay more attention to the girls' themselves rather than their twintails, which he treats as him "betraying" twintails, which causes his bracelet to malfunction, which turns him into a girl and gradually depowers Tail Red.
- Wham Line: In Episode 11:Tail Red: I've turned my back on twintails!
- Your Answer to Everything: Twintails, full stop.
Aika Tsube/Tail Blue
Voiced by: Yuuka Aisaka (Japanese), Sarah Wiedenheft (English)
- Age: 15Birthday: August 8 (Leo)Height: 157cmWeight: 46kgThree sizes: B72/W56/H80
- Absolute Cleavage: Tail Blue's outfit, which is noted to look like it's meant for someone with a much larger bust, like Twoearle.
- A-Cup Angst: Doesn't like having her small chest mentioned.
- Subverted in Episode 3. Twoearle says she doesn't think the Tail Blue suit looks as good on flat-chested women, then flinches, expecting Aika to beat her up (again)... instead, Aika says she only cares about protecting Souji.
- In Episode 5, after confronting an Elemerian with a large-breasts affinity, Aika begs Twoearle to make her a new bracelet that will give her bigger breasts when she transforms. Twoearle agrees, but it doesn't work.
- In Episode 6, Krakeguildy and Leviaguildy's respective opinions on flat chests infuriate Aika so much that she proceeds to break free from Krakeguildy's tentacles and beat Leviaguildy to death with her bare hands.
- Again in Episode 10, where after Fleaguildy points out her flat chest, she proceeds to violently kick him to death, completely forgetting her bet with Souji that she could settle the next battle peacefully.Fleaguildy: From your breasts to your legs...one fine, straight line...
- And again in Episode 11, where Aika is initially quite envious of the fact that Sora/Female Souji is actually quite well-endowed. Lampshaded by Twoearle, which earns her another punch to the face for her trouble.
- Berserk Button: Blue has been driven to beat Elemerians to death by comments about her chest on at least two occasions. It's also a common provocation for beating up Twoearle.
- Blade on a Stick: Tail Blue's main weapon, doubles as a Prongs of Poseidon.
- Butt-Monkey: It's a Running Gag that everyone hates Tail Blue and/or teases her over her flat chest.
- Charles Atlas Superpower: Having studied martial arts for most of her life, she's extremely powerful even without the use of her Tailgear. Poor Twoearle.
- Childhood Friends: With Souji.
- Clingy Jealous Girl: Twoearle's constant advances on Souji is a surefire way to piss off Aika. Unusually for her status as the violent girl in a harem comedy, she tends to take her anger out directly on Twoearle rather than Souji.
- Deadpan Snarker: Particularly directed towards Souji and his twintail fetish.
- The Dreaded: She quickly becomes this for Ultimaguil for her monstrous strength and temper. For comparison, they're infatuated with Tail Red even as she defeats them.
- Eye Colour Change: From red (civilian) to light blue (Tail Blue).
- Hair-Trigger Temper: Mostly around Twoearle, who has come to view her as a barbarian.
- Hero with Bad Publicity: As Tail Blue. The media... haven't been as enthusiastic with Tail Blue as they are with Tail Red, much to Aika's dismay. Not so obvious in the anime, but in the light novel, it's more or less spelled out that Twoearle deliberately spread bad press about Tail Blue onto the internet as a way of getting back at Aika for regularly beating her up.
- Jumped at the Call: When given a chance to become a Twintail warrior herself to help out Souji, Aika accepted without any hesitation and is a pro right from the start.
- Lady Looks Like a Dude: Due to being totally flat chested a few Elemerians mistake her for being a girly guy.
- Leotard of Power
- Making a Splash: Her element.
- No-Holds-Barred Beatdown: She delivers one to Leviaguildy in Episode 6 after Krakeguildy infuriates her with a speech about flat chests. She later gives one to Fleaguildy for the same reason.
- Only Sane Man: Aika as Tail Blue, particularly during battles. She started fighting in the first place when Tail Red was unwilling to attack a doll made in her own image because "the twintails had done nothing wrong". This goes out the window when her Berserk Button is pressed, though.
- OOC Is Serious Business: In the novels, people will often show concern when she's not pulverizing Twoearle.
- Red Eyes, Take Warning: When not using her Tailgear, her eyes are red. When not using her Tailgear, she's still frightening strong.
- Rock Beats Laser: Twoearle's robot guards, made from her world's superscience are essentially useless against her.
- Signature Move: Execute Wave.
- Stripperific: After Erina, her Tail Blue outfit is definitely the skimpiest of the trio.
- Tsundere: Subverted. While Aika is very aggressive, she is rather cordial with Souji (though his profile states she was more aggressive toward him until Twoearle came along). She also doesn't really bother with hiding how happy she becomes when Souji compliments her.
- Undying Loyalty: The reason Aika even became a Twintail in the first place is so she could protect Souji and fight at his side.
- Unstoppable Rage: Gets very violent when her breasts are mentioned.
- Violently Protective Girlfriend: Even the slightest act of perversion toward Souji will bring Aika's wrath upon Twoearle. She'll also kick the ass of any Ultimaguil member who threatens Tail Red.
- Why Did It Have to Be Snakes?: She absolutely hates tentacles and freaks out when stuck facing enemies who have Combat Tentacles. Fortunatly for her this isn't a Hentai series so it never goes as far as what might be expected.
- Wrestler in All of Us: She uses wrestling moves to punish the sexually aggressive Twoearle.
- You Gotta Have Blue Hair: Light blue as Tail Blue.
- Zettai Ryouiki: Grade A black thigh high stockings. She's only missing the Tsundere aspect to complete rank S.
Erina Shindou/Tail Yellow
Voiced by: Chinatsu Akasaki (Japanese), Mikaela Krantz (English)
- Age: 16Birthday: December 21 (Sagittarius)Height: 143cmWeight: 40kgThree sizes: B69/W53/H72
- Arranged Marriage: As an Ojou, it was expected for this to crop up at some point. Specifically, the circumstances regarding her mother trying set one up for her drove her to temporarily give up her twintails as a form of rebellion. It's...complicated. Long story short, it endangered the team's composition, so Souji took it upon himself to do something about it. By taking the issue straight to her mother. The end result: No more marriage talks, but Erina's mother strongly encourages her to take Souji as her husband in the future. His love for Twintails makes him "a real man" in her eyes. ...Yeah, that's Twintails for you.
- Beam Spam: Her shtick, whose frame contains a quartet of beam cannons for this purpose.
- Boobs of Steel: As Tail Yellow.
- Covert Pervert: Erina appears to be the perfect Ojou, well-mannered, poised and completely flawless and untouched by corruption. But give her even the slightest opportunity and she'll eagerly reveal one of her favorite interests: masochistic/exhibitionistic play with Mitsuka. She's propositioned him to beat her, make her his dog, watch her strip, and more.
- Delusions of Doghood: She actually puts on a collar and leash and wants Souji to be her master. She also obeys commands like "sit" from anyone who holds the leash.
- Diving Kick: Her Finishing Move after being propelled by her cannons.
- Girly Girl with a Tomboy Streak: She's secretly a huge fan of heroes and robots.
- Hair of Gold, Heart of Gold: She's an incredibly sweet girl with blonde hair, which seems to become a more intense shade of yellow when she becomes Tail Yellow.
- Hero with Bad Publicity: Tail Yellow's reputation isn't anywhere near as bad as Tail Blue's, but she's still viewed as lewd.
- If It's You, It's Okay: Her masochism is intended solely for Souji, and she feels embarrassed about submitting like a dog to Twoearle.
- I Just Want to Be Special: A mild case of this: she's always wanted to be the hero instead of the Distressed Damsel.
- Ojou: Speaks very formally.
- Older Alter Ego: Her transformation into Tail Yellow makes her grow considerably both vertically (she's normally not even five feet tall) and horizontally.
- Orgasmic Combat: She does a lot of blushing, panting, and moaning when unleashing her powers. Souji is creeped out, while Twoearle is amused.
- Perfectly Arranged Marriage: She's pretty cool with her Arranged Marriage to Souji.
- Power Limiter: She gets more powerful by shedding sections of her armor.
- Power-Strain Blackout: She faints after using full power.
- Sex Is Violence: She seems to be this, to the point where in Episode 7, after Souji gently cups her face in his hands, she immediately (and quite enthusiastically) insists that he slap her harder.
- Shock and Awe: Her primary Element.
- Shameless Fanservice Girl: Erina becomes one when transformed into Tail Yellow, gradually stripping off more and more of her armor while looking a little too enthusiastic about it. In Episode 7, Twoearle seems to encourage her to become a Shameless Fanservice Girl 24/7, apparently so she can control her powers better.
- Signature Move: Voltic Judgment.
- Spock Speak: She is as well-spoken as an ojou at all times.
- Student Council President: Of Yougetsu Private Academy.
- Tareme Eyes: In contrast to her mother's Tsurime Eyes.

- Age: UnknownBirthday: UnknownHeight: 161cmWeight: 50kgThree sizes: B90/W57/H85
- The Atoner: Despite being a walking example of sexual harassment, it turns out that she is partly this. As the former Tail Blue, she feels responsible for what happened to her world, and she really doesn't want Souji's world to suffer the same fate.
- Beauty Is Never Tarnished: Souji is often impressed at how quickly Twoearle recovers from Aika's constant beatings. The novels imply that her otherworldly heritage makes her inherently more durable than the average human. Averted at one point in the first volume when Aika taking the Tail Blue Tailgear by force puts her in a neck brace.
- Big Breast Pride: Which makes her all the more infuriating to Aika.
- Butt-Monkey: Is constantly being attacked by Aika, though she brings basically all of it on herself.
- Comedic Lolicon: She admits to designing Tail Red as a little girl for her own tastes.
- Cool Mask: As Kamen Twintail. Her outfit is otherwise the same as usual.
- Gadgeteer Genius: She builds everything that the Twintail Warriors use.
- Gainaxing: Often.
- Hyperspace Arsenal: Her lab coat's pockets appear to have their own dimensions.
- Human Aliens: Comes from another planet, and is humanoid in appearance.
- Hypocritical Humor: She considers Dark Grasper creepy for following her while using a magazine to conceal her face, making her touch her breasts, and crawling into her bed at night. Aika angrily points out that Twoearle has done each of these to Souji.
- Iron Butt Monkey: Implied in the novels to have superhuman endurance, allowing her to suffer beatdown after beatdown from Aika and look none the worse for wear.
- Legacy Character: It turns out that Aika isn't the first Tail Blue. That used to be Twoearle's role, before she sacrificed her own Affinity to create the Red Tail Bracelet.
- Lovable Sex Maniac: And how. Some of the novel illustrations have shown her literally drooling over Souji, and she generally takes every opportunity she can to flaunt her body toward him or offer some sexual activity. Souji's mom giving her blessings just makes things worse.Aika: You perverted woman! Why is your mind always in the gutter!?"Twoearle: What's wrong with a female being in heat with a male!?
- She's an out-and-proud Comedic Lolicon and twintail fetishist (though, weirdly, she claims not to be into yuri), to the point that when Souji and Aika ask why the Tail Red bracelet turns a male wearer into a girl, she bluntly responds that it's because that's her fetish, before angrily asking if they have a problem with that. Which, depending on how you interpret that, may imply she has a Gender Bender fetish too.
- Mission Control: Often stays in their underground base to give Tail Red and Tail Blue information and strategy during their fights.
- Ms. Fanservice: Very much so.
- My Greatest Failure: Twoearle was the original Tail Blue, but her efforts ended up dooming her world as she played into the plans of the Ultimaguil by becoming a heroine to begin with as a hero, her twintails became popular and emulated by the people of her world, but this in turn just made her world even more of a target of the invaders. And what's worse, when she finally realized what was happening, she couldn't simply stop wearing her twintails either.
- Mystical White Hair: Her silver hair color is what tells Souji that she's not of this world.
- Non Action Girl: Having imparted her twintail element to Souji and her Tailgear to Aika, her role is purely supportive. She eventually gets back into action, if only temporarily, as Tail White.
- Punny Name: On "twirl".
- Slapstick Knows No Gender: A constant victim of Aika's attacks, generally for her perverted behavior toward Souji or mocking her flat chest.
- Spell My Name with an "S": Is it Twirl? Thouars? Toharle? Or Thuearle? Crunchyroll uses the latter, by the way, while the author uses Thoearle. Funimation uses Twoearle. Whatever you decide to use, her name is a pun on "Twirl".
- The Tease: How much of it is on purpose is unclear, but it's more than enough to rile up Aika with her, ahem, choice of words.Twoearle: Here! Put it on that great, big tree trunk of yours!
- Troll: She especially loves to goad Aika in regards to her flat chest.
- Vague Age: Her profile keeps her age a secret, though she claims to be the same age as the other protagonists.
- Victoria's Secret Compartment: Where she often keeps the remotes for her devices, despite wearing a lab coat tailor-made to maximize pocket space.
UltimegilAn organization composed of extraterrestrial beings called Elemerians and Ultiroids, invading Earth in search of a variety of "attributes".
- Batman Gambit: How the Elemerians conquered Twoearle's world. They knew someone would rise up against them, so they leaked some of their advanced technology to hasten the process. When Twoearle appeared as Tail Blue, her entire world fell in love with both her and her twintails, making her world an even bigger target, and even when Twoearle realized this, her Twintails Affinity meant she just couldn't bring herself to abandon the hairstyle.
- Defeat Equals Explosion: How the Elemerians die.
- Emotion Eater: The Ultimegil are a goofy, comedic version of this, but rather than emotions per se, they drain "attributes" the pleasure a sentient being feels when doing something they like.
- Evil Is Hammy: Being a Sentai parody, this is to be expected.
- Fetish: Each of the Elemerians have personal "attributes"... most of them being well-known otaku fetishes like bloomers, maids, or model-building. Twintails are just their main target.
- Harmless Villain: Almost, they invade Earth for its "attribute" strength rather than world domination.
- I Regret Nothing: Many of the defeated Ultimegil express regret that they could not indulge in their respective fetishes one last time before dying.
- Irony: Many of the Ultimegil kaijin are enthusiasts of a specific "attribute", and yet they are obliged by being part of Ultimegil to drain said affinities from their victims. Twoearle lampshades on how paradoxical it sounds, akin to a fan driven to destroy the object he or she became a fan of to begin with.
- Laughably Evil: Most of them. Some, like Dragguildy and Spiderguildy, on the other hand, have shown to be capable of putting up a decent fight.
- Mega Manning: The Elemerians drop Elemera crystals when defeated that represent their affinities. Turns out, these could be weaponized and used. While Souji would rather stick to using his default Twintail power, Aika has no qualms about using Turtleguildy's bloomer attribute (which gives her Gravity Powers) against Foxguildy.
- Otaku: The Ultimegil are, when you get down to it, otaku kaijin, with a bit of Dirty Old Man thrown in for good measure. Observe how they perv out on what each of them plan to do with Tail Red when they get their turn to fight her.
- Punch-Clock Villain: The kaijin are merely following the orders of their leader, and hold no malice toward humanity.
- Serious Business:
- The Elemerians' fetishes. They seriously get sidetracked in their discussion on how to deal with Tail Red... by one of them making a Tail Red model, and the other thinking about dressing her up in a maid costume.
- Heck, their selection process for missions is all this. Full-contact jenga?
- Swan Guildy is denied the chance to fight Tail Red because the nurse-themed "eroge" he's playing isn't actually an eroge...or something.
- Theme Naming: The names of most, if not all, Elemerians are in the form of "(Animal)-guildy". Lizardguildy, Turtleguildy, Foxguildy... the list goes on.
- Your Answer to Everything: It varies on the Elemerians' fetishes.
A faction of Ultimegil, primarily focused on the otokonoko attribute. Their Elemerian members include Bettleguildy, Stagguildy, Wormguildy, Spiderguildy/Arachneguildy, Hopperguildy, Snailguildy, Papillionguildy, Fleaguildy, and Mantisguildy.
- Ambiguously Gay: Given that they, as a whole, are after the otokonoko attribute, it's easy to paint them as this.
- Animal Motifs: Insects, exceptions being Snailguildy (gastropod) and Spiderguildy (arachnid).
- Big Creepy-Crawlies: Well, they're insectoid extraterrestrial beings, after all.
- Even Evil Has Loved Ones: When Wormguildy is slain, all of his comrades weep and emote about how much they cared about him.
- Insectoid Aliens: Insectoid Elemerians, to be exact.
- Serious Business: Otokonoko.

- I Regret Nothing: When he is mortally wounded by Tail Red, he says to be killed by a beautiful girl was exactly how he wanted to die.

- Tin Tyrant: Wears black armor.
- Turns Red: Sprouts a pair of blonde twintails after his back was wounded by Tail Red.

For one, she's not only okay about this whole son-is-a-genderswapping-heroine nonsense, she's also fine with Twoearle converting the basement of her house into a secret base, never mind her complete blessing for Twoearle to jump Souji's bones. In the light novel, she admits that both she and Souji's father were stricken by a serious case of chuunibyou, which is why she was totally okay with her son being a hero by proxy, as he was living his parents' fondest dreams.Miharu: Sou-chan, your mother grew up with an aggravated case of chuunibyou. I passed my days dreaming of becoming a heroine who protected the world, and it finally didnt come true and I became a mother of one.
