[[folder:Northern Territory]]

!!Minato Sahashi
->'''Voiced by:''' Creator/ShinnosukeTachibana (JP), Creator/JoelMcDonald (EN)

The Ashikabi of the North, and the main protagonist of the story. He has failed college entrance exams twice, due to his inability to deal with pressure. As a result he's considered as an idiot and a loser. His life changes immensely when he first meets Musubi and becomes her Ashikabi. As he gains more Sekirei over the course of the story due to his kind heart, he becomes a pivotal and powerful player in the Sekirei Plan.

'''Sekirei:''' Musubi, Tsukiumi, Matsu, Kusano, Kazehana, and Homura

* AboveTheInfluence: Minato is trying his best to remain a gentleman...even with all his Sekirei hitting on him.
* ActionSurvivor: He has no special powers of his own beyond being able to wing his Sekirei. Still, he's gutsy enough to put his life on the line on the battlefield.
* AllLovingHero: Evolving into this as time goes on.
* ApologisesALot: Though he's getting a bit better.
* BigBrotherInstinct: He has it, but in the past he was bad at following through with it. Is doing a much better job with Kuu.
* BigGood: For having a lot of loving, very powerful Sekirei.
* {{Bishonen}}: He's a slender, boyishly-handsome young man, though unlike some of the other Ashikabi, his feminine looks emphasize his own apparent weakness rather than his attractiveness.
* BiTheWay: Claims he isn't, but nobody ''really'' believes him. His tendency to have dreams where his Sekirei have all become muscular men, and the ease at which he's able to accept having a male Sekirei support this.
* BlackComedyRape: While discussing over-the-top ideas about the major powers in the Game, a group of Ashikabi express their fear of being molested by the Ashikabi of the North.
* BloodSplatteredInnocents: In the manga, [[spoiler: Uzume]] dies in his arms. He's left covered in her blood, shocking the others when they return home.
* BookDumb: He does not do well under pressure. When Matsu gives him a sample college entrance exam, he aces it entirely, causing her to wonder how the heck he failed it twice. She also mentions that the test she gave him was a lot harder than a normal exam as well.
* BookEnds: The story starts with Musubi falling onto him. Guess how it ends.
* ButtMonkey: Minato's never safe from the suffering his mother and sister put him through.
* CallingTheOldWomanOut: Subverted when Minato finally calls Takami while protecting his Sekirei. She's proud of him for what he's done, but, being the {{troll}} she is, ends up arresting him and the Sekirei anyway.
* CelibateHero: Not that he ''isn't'' sexually attracted to his Sekirei (apart from [[TokenMiniMoe Kusano]]), just that he's resolved to avoid sleeping with any of them until they've escaped the Sekirei Plan and ensured that they can be together forever.
* CharacterDevelopment: His experiences and love for his Sekirei has allowed him to become a much stronger person, impressing Seo with his determination. He states it's his desire to become "someone worthy" of the faith everyone has in him.
* ClosetKey: A bisexual-variant, for Kagari.
* CoolDownHug: Gives a literal one to an overloaded, suicidal [[spoiler:Homura]]. Lampshaded after he attempts to resolve a conflict by hugging [[spoiler:Uzume.]]
-->'''Homura''': ''Is hugging....one of your specialties or something?''
* CowardlyLion: Normally meek and insecure, but when push comes to shove he's stood his ground against enemy Sekirei without a second thought.
* DareToBeBadass: [[spoiler:After Uzume's termination]], Miya tells him there's only one way to restore the broken bonds of defeated Sekirei.
-->'''Miya''':''Hope lies in the last remaining one who has overcome every catastrophe since the time of legends. Sahashi-san, do you have the courage to take that position?''
* DeclarationOfProtection: He wants to protect the Sekirei who eventually choose him.
* TheDitherer: Because of his insecurities, before his CharacterDevelopment.
* TheDreaded: Minato is surprised to learn people are 'terrified'' of the "Ashikabi of the North". Suffice to say, he doesn't live up to his reputation.
* ExtremeDoormat: Eventually subverted. Minato's often pushed around by his sister and mother, but stands up for his friends when it counts.
* FromNobodyToNightmare: He went from a unlucky high school student to a powerful Ashikabi involved in the Sekirei Plan.
* GagPenis: Matsu is rather.....''pleased'' the first time she sees Minato naked.
-->'''Matsu''': ''But Mina-tan, the data down here is much more than I expected..!''
* GameBreaker: An in-universe example. Minato gets called out by Higa as being one during the 4th stage of the Sekirei Plan; thinking that Minaka had purposefully set the system up so that Minato would end up with a majority of the top-level Sekirei.
* GoodIsNotDumb: Once Matsu hammers into him how capable he is, he begins taking an active role in strategy and tricking the enemy.
* GoThroughMe: Shields his injured Sekirei from attackers on multiple occasions, refusing to back down even from the very real possibility of being squished like a bug.
* GuileHero: Thanks to Matsu, he's finally realizing how to best take advantage of his NonActionGuy status. He's managed to run a gambit on Higa, and came up with effective strategies to outsmart enemies.
* GutFeeling: He's rarely wrong about people, seeing the good in the JerkWithAHeartOfGold while steering clear of the ManipulativeBastard trying to make friends.
* HeroicBastard: Everyone but Minato seems to know his biological father is [[spoiler:Minaka.]]
* HeroicSelfDeprecation: Due to his low confidence, though he's improving.
* HeroWithBadPublicity: He has a reputation as a DepravedBisexual among the Ashikabi community, due to his harem. People are ''shocked'' to learn the Ashikabi of the North is a pretty mild guy.
* HopeBringer: He's decided to become this, and it shows.
* HouseHusband: Handles all manner of household chores, and generally plays the supportive domestic to his Sekirei.
* IDidntMeanToTurnYouOn: Most Ashikabi get past this after the winging, poor Minato still has to deal with this.
* IncorruptiblePurePureness: He experiences temptations, but his moral compass is strong enough that he rejects them.
* InnocentCohabitation: With his Sekirei. Miya has threatened to kick him out, if it doesn't ''stay'' that way.
* InsecureLoveInterest: He often worries that he isn't worthy of his Sekirei.
* JustTheWayYouAre: As Kagari's Ashikabi, Minato has the power to determine his gender and mentality, but chooses to let Kagari remain who he is for now.
* TheLeader: [[spoiler: He becomes this when the final Stage is interrupted by a military invasion, taking charge and uniting the rival Ashikabi to defend the island]].
* LockedOutOfTheLoop: He's only told key info when absolutely necessary. Otherwise he's kept in the dark.
* LoserProtagonist: Initially comes off as one, having failed his college entrance exam twice and being unemployed and all, but we come to learn that [[SubvertedTrope he was never one at all]]. He possesses a near genius level IQ and proves himself to be TheParagon time and time again.
* LoverTugOfWar: Often the target of this, usually involving Tsukiumi and Musubi.
* LustObject: To Matsu.
* [[MadScientistsBeautifulDaughter Mad Scientist's Innocent Son]]: Minaka's son, kept in the dark about his father's true identity. When Higa accuses him of gaining so many powerful Sekirei because of his father, he's understandably confused.
* MagneticHero: He has a way of bringing together other Ashikabi, who are inherently rivals due to the nature of the game.
* AManIsAlwaysEager: Subverted. He's generally more flustered and nervous about the idea of sex than most of his harem.
* MarryThemAll: His intention is to be with each of his Sekirei for the rest of his life.
* MasculineGirlFeminineBoy: The feminine boy to his sister Yukari's masculine girl.
* MysteriousParent: Knows absolutely nothing about his father, unlike.....well....pretty much every single other character.
* NiceGuy: A kindhearted and understanding guy all around.
* NonActionGuy: He has no fighting ability, and spends most of the early series leaving the action to his Sekirei. Later on he graduates into being something of an ActionSurvivor, as while he still does almost no fighting on his own, he becomes much more active on the battlefield when supporting his Sekirei.
* NoseBleed: For appropriate comedic effect.
* NotWhatItLooksLike: Miya and Tsukiumi are usually the ones he's trying to explain himself to.
* TheParagon: Routinely shows himself to be devoted to helping others and inspiring them to improve themselves, regardless of who they are or if it means putting his life on the line.
* PowerOfTrust: Considers himself unreliable, but inspires trust in others. His faith in others is almost always rewarded.
* {{Protectorate}}: All of his Sekirei and him in turn for them.
* PunchedAcrossTheRoom: Of all Sekirei he has ironically Kagari is the only one who punched him to the point he fainted for a while.
** Tsukiumi also did the same but using her water.
* TheRedBaron: "The Ashikabi of the North". In fitting with the others that control a territory, he's also sometimes called "Minato of the North".
* RidiculouslyAverageGuy: He starts out seemingly as one.
* {{Ronin}}: He has failed college entrance exams twice.
* ScrewDestiny: Determined to do this, and earn a happy ending for ''all'' the Sekirei and their Ashikabi.
* SecondLove: To Kazehana.
* SensitiveGuyAndManlyMan: The Sensitive Guy to Seo and Kagari's Manly Men.
* SuspiciouslySpecificDenial: "[[HaveIMentionedIAmHeterosexualToday I'm happily hetero]]!" Unconvincingly said by Minato to Tsukiumi to try reassure her when she thinks he's cheating on her with Kagari.
* TellMeAboutMyFather: He attempted to ask about his father, but was asked not to ask Takami about it again, given his father is the BigBad.
* ThanksForTheMammary: Happens accidentally to him a few times.
* ThisLoserIsYou: He's a pretty average guy, right up until Musubi literally crashed into his life.
* TiredOfRunning: Rejects multiple chances to quit the Sekirei Plan and escape the city, and after [[spoiler: Uzume's termination]] makes the decision to fight with the intention of winning.
* TrueCompanions: One of his most appealing traits that has made his Sekirei love him and a formidable group.
* UnderstandingBoyfriend: Takes the whole "Battle Alien" thing in stride. And takes Kagari's unstable gender in stride, simply stating that Kagari is fine as himself.
* YouAreBetterThanYouThinkYouAre: Both the giver and receiver of this trope, in particular when talking down a suicidal Kagari.
* YouAreNotAlone: A defining part of his interactions with others, especially as the series progresses and he becomes more confident.

!!Musubi #88
->'''Voiced by:''' Creator/SaoriHayami (JP), Creator/AlexisTipton (EN)

Minato's first Sekirei. She is somewhat dim-witted and clueless, but holds an incredible strength of will and compassion for others. A power-type Sekirei, she is a close-combat fighter with amazing strength. [[spoiler: As a child, she was kidnapped by unknown forces and rescued by the 2nd Discipline Squad. Her core was badly damaged during her captivity, driving Yume to sacrifice her own existence and pass her core on to Musubi.]]

'''Ashikabi:''' Minato Sahashi

* ActionGirlfriend: To the core! She appears when Minato needed her most and turning his life upside-down.
* AffectionateNickname: Karasuba calls her "Mu-chan".
* AllLovingHeroine: Her goal is ultimately to win the Sekirei Plan, in order to [[spoiler: teach Karasuba to believe in ThePowerOfLove and in order to free all the Sekirei so everyone can be happy]].
* AllYourPowersCombined: [[spoiler: In chapter 177, she temporarily assimilates the Sekirei core of the rest of Minato's harem, and their powers, in order to revive Minato and take on #00.]]
* AnimalMotifs: Bears.
* BadassAdorable: She's adorable, even when she's smashing buildings with her fists.
* BareHandedBladeBlock: Pulls a couple off.
* BearsAreBadNews: Occasionally manifests a [[LoomingSilhouetteOfRage bear]] behind her, which terrifies the others. Also, her special attacks are Bear-themed.
* BetweenMyLegs: In episode 2.
* BigEater: The first time Minato feeds her, she leaves him broke.
* BiTheWay: She finds groping Tsukiumi.....''exciting''.
* BoobsOfSteel: A power-type Sekirei with super strength, and a big deal is made of her enormous chest.
* BuxomIsBetter: Musubi is compared to (and considered sexier) than [[TheLoad Kuno]] because of her big boobs. She's also one of the bustiest girls in Minato's harem, second only to [[ImpossibleHourglassFigure Kazehana]].

* CatSmile: She does this on occasion, in particular with Kusano.
* CloudCuckoolander: At times.
* CovertPervert: Though Matsu is more obvious about it, ''Musubi'' might actually be the most perverted of Minato's Sekirei; [[LesYay she kisses Matsu without batting an eye, likes having her breasts fondled by Yukari, enjoys groping Tsukiumi]], gets off on being BoundAndGagged by Karasuba...
* CrashIntoHello: Landed on Minato.
* CuteBruiser: Her primary characteristic.
* {{Determinator}}: She even learned a new attack this way.
* TheDitz: She's not the brightest Sekirei around.
* DueToTheDead: Musubi is shown to take ''very seriously'' the rule about guarding a terminated Sekirei until they can be retrieved by MBI.
* DumbIsGood: Though the least intelligent of Minato's Sekirei, she's easily the nicest, and the only one who respects his boundaries and/or isn't [[DoubleStandardAbuseFemaleOnMale comically abusive]] towards him.
* FingerlessGloves: Hers happen to have extra padding to protect her knuckles.
* FriendlyEnemy: Insists her friendship with Kaho is ''really strong'', partially because they promised to fight next time they met. HilarityEnsues when they meet pre-battle, and are forced to hide from each other to avoid breaking their promise.
* GenkiGirl: Perky, sweet, and ''never'' one to give up!
* TheHeroine: Drives the story with her personal quest to free all Sekirei.
* HorribleJudgeOfCharacter: She's incredibly fond of [[FauxAffablyEvil Karasuba]]. [[spoiler: Subverted, as it turns out. She isn't fooled by Karasuba for one minute, but shares Yume's desire to teach Karasuba the error of her ways, even describing her as a child that just doesn't understand a Sekirei's true nature and purpose.]]
* IdiotHair: Showing her innocence. It tends to react depending on her emotions.
* {{Idiot Hero}}ine
* ImmuneToBullets: She found being shot, and hit, by machine guns near the end of the fourth stage "annoying."

* LimitBreak: Kuma Ryusei (Bear Meteor).
* MagneticGirlfriend: Winging her unlocked Minato's potential, allowing him to slowly attract all the others in his harem.
* ManicPixieDreamGirl: To a degree. She literally falls out of the sky into Minato's life and ends up kicking off an adventure that makes him a more confident person. However, while she's quirky, she herself is only as responsible for Minato's CharacterDevelopment as any other Sekirei is.
* MegatonPunch: One of her signature moves.
* {{Miko}}: Her outfit [[InvokedTrope invokes]] one aesthetically, anyway.
* MoralityPet: To Karasuba.

* RedOniBlueOni: The red to Tsukiumi's blue.
* SharingABody: [[spoiler: Yume continues to exist within her soul, and sometimes takes control.]]

* SpiritedCompetitor: She loves to take on strong opponents.
* SuperMode: [[spoiler: Has one in the form of Yume, her Alter Ego.]]
* SuperStrength: Her primary ability as a Sekirei.
* ThirdPersonPerson: Zigzagged. Sometimes she refers to herself by name, sometimes she doesn't. There really doesn't seem to be any consistency.
* UndyingLoyalty: She's willing to stay by Minato's side and protect him always.
* YouAreNumberSix: #88
* YouMonster: A random soldier mook calls her one. She replies that he's being rude before megaton-punching him off Kamikura Island.

->'''Voiced by:''' Creator/KanaHanazawa (JP), Creator/TiaBallard (EN)

She was forced out into the world early, after Mikogami attempted to capture her and used her powers to build a forest to protect her.

->'''Voiced by:''' Creator/AyaEndo (JP), Creator/ColleenClinkenbeard (EN)

Minato's third Sekirei, a perverted technopath in hiding from MBI. She originally viewed Musubi as a rival, but quickly decides watching the others fight over Minato is more entertaining. As Sekirei #02, she knows many secrets about the Sekirei Plan and provides the others with information and tactical support from the safety of her room.

* MsExposition: She's the one Minato turns to, whenever he needs information. As such, she's the major source for info-dumps in the series.

!!Tsukiumi #09
->'''Voiced by:''' Creator/MarinaInoue (JP), Creator/LydiaMackay (EN)

Minato's fourth Sekirei, a proud and bad-tempered woman with control over water. She is the youngest Single Number, and initially holds a deep contempt for Ashikabi to the extent she planned to kill Minato. After he defends her, though, she is deeply moved and agrees to become his wife -- considering the other Sekirei his "concubines".

* AnimalMotifs: Both in terms of her ExpressiveHair and snake-themed attacks.
* AntiquatedLinguistics: Speaks in ancient Japanese.

* CuteLittleFangs: When she's angry, which is....often.
* DangerouslyShortSkirt: Often flashes them, to the extent others comment on it.

* LadyOfBlackMagic: Her fighting style focuses on long-ranged elemental attacks, rather than up-close-and-personal fighting. Avoids CripplingOverspecialization with Water Sword, her only but powerful short range attack.
* TheLancer: To Musubi, contrasting her cheerful innocence.
* LimitBreak: Shiomitsu Tama (High Tide Jewels).
* MakingASplash: Her particular power is water.
* MasterOfDelusion: Completely oblivious to the fact she'd been having breakfast with her rival for months. It took seeing him use his powers, remembering there's only one flame-type Sekirei, ''and'' Musubi pointing out their resemblance to make her realize that Kagari and Homura are the same person.
* MeaningfulName: Tsukiumi's name means "Moon Sea".
* OfCorsetsSexy: Built into her coat.

* TsurimeEyes: To match her proud, aggressive personality.
* TwinkleSmile: Gets one in the anime after meeting Minato's first 3 Sekirei.

* YouAreNumberSix: #09
* ZettaiRyouiki: Grade B.

!!Kazehana #03
->'''Voiced by:''' Creator/{{Yukana}} (JP), Creator/StephanieYoung (EN, as Kelly [=McHalen=]])

Minato's fifth Sekirei, a deeply romantic woman that has power over the wind. A shameless flirt, she drinks heavily and enjoys pushing the limits of the rules at Izumo Inn in terms of "indecent behavior". She challenges Minato to prove himself to her, and agrees to become his Sekirei when she witnesses the depth of his love for them. While rarely serious, she is a skilled fighter and one of the strongest Sekirei.

* AbsoluteCleavage: Her dress is slit down past her navel.

* CherryBlossoms: These are the kinds of petals she summons with her powers.
* CombatStilettos: Her heels don't look battle-ready, but she's amazingly agile in them.
* CoolBigSis: Her role in the harem. Minato correctly guesses that she feels this way towards most of the Sekirei, viewing herself as their big sister.
* DramaticWind: Brings her own.
* EthicalSlut: Hinted to be one, readily encouraging others to follow their hearts regardless of social expectations/norms, and playfully scolding Minato for worrying about gender and sexuality when it comes to ~love~.
* HardDrinkingPartyGirl: She loves to drink and party, though it isn't clear just how much of it is a front for her [[BrokenBird issues]].
* HotWind: Generates her own, almost constantly.
* ImpossibleHourglassFigure: In the anime. In the manga her figure is less extreme and at least possible, if unlikely. [[http://www.mangareader.net/163-10801-1/sekirei/chapter-68.html As seen here]].
* InSeriesNickname: Public Obscenity (Miya), The Drunk (Mutsu)

* ShamelessFanserviceGirl: Much to Miya and Homura's annoyance.
* ShesGotLegs: Shown to fantastic effect by her DangerouslyShortSkirt and tendency to be shown [[IHaveTheHighGround atop high locations]].
* SingleWomanSeeksGoodMan: She asks Minato to prove himself "a man", but in the end it's his kind heart that wins her over.
* SuperPrototype: Due to the special adjustments Takehito gave her.
* TheTease: She ''loves'' to tease everyone. No one is safe, except for Miya.
* WalkingTheEarth: Claims to have done this for a while, but admits it turned into a national Sake taste-testing tour.
* YouAreNumberSix: #03
* YoungerThanSheLooks: She is, at most, the same age as Minato.
!!Homura #06[=/=]Kagari

Minato's sixth Sekirei. One of the residents of Izumo Inn, he goes by the alias of "Kagari" and works at a Host Club while concealing his identity as a Sekirei. He also serves as the Sekirei Guardian and wields power over flames, protecting unemerged Sekirei from harassment by humans or attacks by other Sekirei. Stated to be a prototype, his powers are extremely unstable and he has no default gender, though requested to be male. Over time, his body begins to change gender in reaction to Minato and in despair, he attempts to either kill Minaka or himself. After being talked down by Minato and be emerged, he comes to accept himself.

'''Ashikabi:''' Minato Sahashi

* AbsoluteCleavage: Once he's emerged, he starts wandering around with his shirt unbuttoned very low. An omake features Minato worrying about how Kagari doesn't seem to realize it, and he's not sure where he's supposed to [[MaleGaze look]] anymore.
* AloofAlly: Before becoming Minato's sixth Sekirei.
* AnimalMotifs: All his named attacks are themed after snakes or dragons.
* AttractiveBentGender: It's...complicated. Homura is introduced as a very handsome young man, but after beginning to react to Minato he starts to turn into a woman. He's still really attractive in his new feminine form.
* BadassLongcoat: Wears one as the Sekirei Guardian.
* {{Bishonen}}: The most popular Host at his club.
* BigDamnHeroes: He is this to unemerged sekirei he saved.
* BrokenBird: His powers and physical sex are highly unstable, which gives him complicated body and gender issues. As a result of this, he believes himself to be broken and plans to murder Minaka or die trying. His suicide attempt is interrupted by Minato, who convinces him to go on living. He's very slowly beginning to get better.
* ByThePowerOfGrayskull: ''These are the flames of my pledge, burn the Karma of my Ashikabi.''
* CanNotSpitItOut: Completely unable to confess his feelings.
* TheCasanova: Before reacting to Minato.
* CompensatedDating: Shown going on one with Takami, in order to make up for the time he took off to protect Kusano.
* CrossdressingVoices: In all languages, even before developing female characteristics. It may have been intended to serve as foreshadowing for his unstable, genderless body.
* DeathSeeker: Believed he could not live for himself, and intended to die rather than be Minaka's pawn. Minato talks him out of it, with a bonus CoolDownHug.
* DontYouDarePityMe: Minato responds by insisting it isn't pity.
* FalseReassurance: Homura's infamous "This doesn't interest me at all" line.
* FlawedPrototype: Let's just say he has issues.
* {{Gayngst}}: Goes through a ''lot'' of emotional problems after he starts reacting to Minato. These only become worse as his body begins to become female as a result of them.
* GayOption: While he begins developing female characteristics after reacting to Minato, he continues to identify as male, and his relationship with Minato is for all intents and purposes treated as being between two men.
* GenderBender: Once he began to react to Minato's presence, Homura's body became like that of a female's while retaining his male mind. However, it's heavily implied that the transformation wasn't completed and he retains a certain significant male part.
* {{Hermaphrodite}}: Implied. Ever since he began to react to Minato, Homura has gained a feminine body structure and breasts, but he compares himself to a slug (an animal with both sexual organs), and implies that while his overall appearance is female, he still has certain male parts intact.
* HostClub: Works at one, and is their #1 Host.
* HypocrisyNod: See AbsoluteCleavage above, in the same omake Homura scolded Kazehana for wandering around only in a bathrobe and exposing a good portion of her chest. In case of Kazehana however, her everyday outfit expose as much so it's a wonder why Homura is bothered by her lack of modesty. Homura himself as mentioned above starts buttoning his shirt very low since he became Minato's sixth sekirei. Lampshaded by Minato, the lack of modesty also applies to Homura but for some reason he didn't notice.
** It's ironic, considering that, even before his winging, Homura was one of the characters most prone to pointing out the other Sekireis' lack of modesty.
* IfItsYouItsOkay: He wanted to have a female Ashikabi, but ended up reacting to Minato, a man. Homura isn't happy about it and acts quite {{Tsundere}} to Minato, but is slowly accepting his feelings for him.
* IncompatibleOrientation: A more complicated case than the usual. Since Minato is heterosexual, Homura [[GenderBender began to turn into a woman]] after reacting to him.
* InterruptedSuicide: Refusing to be a trophy in Minaka's "Game", Homura attempted to commit suicide through self-immolation. Minato and his Sekireis arrived just in time to stop him and Minato initiated his emergence, saving his life.
* LadykillerInLove: Towards Minato.
* LastNameBasis: Homura still uses Minato's family name, unlike his other Sekirei.
* LeaveMeAlone: Often throws this at Minato, when he tries to help.
* LimitBreak: Gouka no Tsubasa (Wings of Conflagration).
* MeaningfulName: Homura simply means "Flame". His alias of "Kagari" also counts, as it was purposefully chosen for its meaning, "Bonfire". He explains it as reflecting his wish to protect and guide unemerged Sekirei. Later, he admits this desire to protect and guide now applies to Minato.
* MysteriousProtector: Was this at first for wingless Sekirei at Takami's request.
* MysticalWhiteHair: A hint of his true nature, as a Sekirei and a rare elemental type.
* NoBiologicalSex: Homura had no set gender to begin with. He asked to be adjusted to become a male, but once he began to react to Minato's presence his body [[GenderBender took the matter into its own hands]].
* TheOneGuy: While his biological sex is a whole other issue, he identifies as male, and is the only male in Minato's harem.
* PaperThinDisguise: Tsukiumi and Musubi still fall for it, though.
** Lampshaded by Homura himself that he only wear face mask, and baffled that Tsukiumi didn't recognize him. Which mean to be fair, he didn't mean his Sekirei outfit to hide his identity at all, and most likely the face mask is simply a practical clothing due to his [[PlayingWithFire elemental power]].
* PlayingWithFire: His elemental ability, and stated by Tsukiumi is completely unique among the Sekirei.
* RedEyesTakeWarning
* SensitiveGuyAndManlyMan: The Manly Man to Minato's Sensitive Guy, ironically.
* SharpDressedMan: Always dressed in fashionable clothing, and Minato admires him for this.
* TheSixthRanger: The last to officially join Minato's team.
* SmokingIsGlamorous: His smoking is typically portrayed as part of his allure.
* TransgenderFetishization: Ever since he began to turn into a woman, Homura gets about as much {{Fanservice}} scenes as the rest of Minato's haremettes.
* TransparentCloset: He fervently denies it, even though he blush and think about his Ashikabi a lot he readily place the blame on Tsukiumi for infecting him. None of his fellow Sekirei believes him, especially Tsukiumi who feels jealous towards him if he gets too close to Minato and call him cheating for using 'we're both guys' as an excuse to offer Minato his room to rest when the others stole Minato's room.
* {{Tsundere}}: Wasting time acting like he doesn't have feelings for Minato. Homura once punches him in the face right after getting all blushy and dere, for crying out loud. It was most severe when he began to react to Minato, but still has shades of it on occasion. He readily blames Tsukiumi for "infecting" him.
* WhiteHairBlackHeart: He has white hair, and while he's a very heroic person, he has a tendency to be blunt and cold towards others.
* WhichRestroomDilemma: There's a RunningGag where he can't decide whether to go in the male or female side of baths or changing rooms.
* YouAreNumberSix

[[folder: Discipline Squad]]

The Discipline Squad is a specialized unit used by [=MBI=] to enforce the rules of the Sekirei Plan. Their membership has changed over the years, but their purpose in eliminating threats remains the same. They are the primary antagonists of the series.

!!Natsuo Ichinomiya
->'''Voiced by:''' Creator/KosukeToriumi (JP), Anthony Bowling (EN)

An MBI clerk for the pharmaceutical department and Ashikabi of the Disciplinary Squad. He is a deeply cynical person, and harbors a deep hatred of the world because of the death of his lover, a military doctor. To most, he comes across as casual and unconcerned about the events taking place around him, with his true intentions known only to Karasuba.

'''Sekirei:''' Karasuba, Benitsubasa, Haihane

* AdaptationDyeJob: A brunette in the anime, but his [[WhiteHairBlackHeart hair is white]] in the manga.
* {{Bishonen}}: Well-dressed and very easy on the eyes.
* CoolCar: He likes to take rides in it with Karasuba.
* DespairEventHorizon: The death of his lover.
* DissonantSerenity: Nothing fazes him, and he keeps smiling cheerfully whether his life is in danger or his Sekirei are brutally slaughtering their victims.
* FauxAffablyEvil: He seems very friendly and polite. However, it's all a cover for how utterly empty inside he is.
* IcyBlueEyes: Completely cold and dispassionate.
* ItAmusedMe: Responded to Karasuba's request to help her destroy the world was, "Sure, why not?". She describes him as a whimsical man.
* TheMourningAfter: His lover was a military doctor, killed in action. As a result, he's given up on the world.
* MrExposition: A source of valuable information when Minato first meets him, revealing just ''why'' attacking an Ashikabi is forbidden by the rules.
* NietzscheWannabe: He casually wonders why Minato doesn't kill him, since doing so would eliminate the Discipline Squad and remove much of MBI's power over the Sekirei.
* NonActionGuy: As typical of an Ashikabi, he sits back and lets his Sekirei do all the killing.
* SharpDressedMan: As befits a representative of the company.
* StepfordSmiler: A more low-key example. He seems cheerful and carefree, but he's really dead inside and just waiting for the world to end.
* TheStoic: He doesn't show much genuine emotion, unconcerned about the carnage and chaos that go on around him.
* StraightGay: Much to Benitsubasa's frustration.
* {{Synchronization}}: [[spoiler: Karasuba forcefully ripping out her wings really took a toll to Natsuo.]]
* TheTease: Playfully strings Benitsubasa along, giving her an AffectionateNickname and doing absolutely ''nothing'' to discourage her from being a HopelessSuitor.
* WhileRomeBurns: It doesn't matter what kind of chaos the Sekirei Plan has caused or currently causing. He remains calm and isn't bothered. He's angry at the world and no longer cares what happens to it.
* WhiteHairBlackHeart: In the manga, describing himself as "empty" and genuinely unconcerned about the horror Karasuba intends to unleash on the world.
* WoobieDestroyerOfWorlds: [[OmnicidalManiac Karasuba]] offered him the means to destroy the world he hates, during his DespairEventHorizon.
* YouAreNotAlone: [[spoiler: He comes to realize this was the purpose behind Minaka assigning Benitsubasa and Haihane to him, providing him with two Sekirei that would eventually help push him past his despair]].

!!Karasuba #04
->'''Voiced by:''' Creator/RomiPark (JP), Creator/ChristineAuten (EN)

The "Black Sekirei", and longtime member of the Discipline Squad. She is the primary antagonist of the series, and fully intends to destroy humanity if she claims victory. An incredibly skilled swordswoman, she is feared by other Sekirei as a monster because of her strength and blood lust. She longs for the end of the Sekirei Plan, and actively encourages Musubi to become strong enough to challenge her in the final battle.

'''Ashikabi:''' Natsuo Ichinomiya

* TheAgeless: She looks the same age as other Sekirei, but was an adult when all the others were still infants.
* ArchEnemy: Eagerly awaiting the day that she becomes this to Musubi.
* AxCrazy: Death, destruction, and suffering are her bread and butter.
* {{BFS}}: Her ''nodachi''.
* BloodIsTheNewBlack: Played straight, and also used for ''comedy''. She's often left splattered with blood after dealing with targets, and a side story parodies this with Musubi's flashback of a SuperDeformed Karasuba coming to tell her about the new Hot Springs that just opened. Arrows point to splatters of blood, noting it to be from her victims.
* BloodKnight: She lives to take on strong opponents, which is the ''only'' reason she keeps Musubi around as a MoralityPet. She's grooming her to be an opponent worthy of the Final battle.
* ByThePowerOfGreyskull: ''This is the Blade of my Pledge. Exterminate the sworn enemies of my Ashikabi!''
* CloseCallHaircut: [[spoiler: Ends up losing her long hair, when she narrowly escapes Kaho's Norito. Since she's [[CombatPragmatist pragmatic]] to the extreme, she uses her coat and lost hair as a decoy....]]
* CoatCape: She wears her grey coat this way, as did most of the original Discipline Squad.
* CombatSadoMasochist: ''Excited'' by killing, as well as the very idea of facing opponents capable of killing her. [[spoiler: She discusses almost dying at Miya's hands as something positive, and longs to experience it again.]]
%%* CombatStilettos
* ConvenientComa: [[spoiler: Even after the "game" is over, she is still "terminated" because she ripped out her own core, and even Kouten can't revive her.]]
* DodgeTheBullet: Shown to be able to dodge automatic weapon fire at close range, in both the anime's prologue and the Kamikura island flashback. She does it while wearing a full-on SlasherSmile.
* TheDreaded: Everyone fears her. EVERYONE. That Musubi gets along with her shocks many.
* DrivenToSuicide: She goaded [[spoiler: Takehito into making his HeroicSacrifice, by asking if he intended to abandon the Sekirei. He took the bait]].
* EvilCannotComprehendGood: She openly cannot comprehend ThePowerOfLove that drives other Sekirei, and expresses disgust upon sensing positive emotions through her bond with Natsuo.
* EyesAlwaysShut: Only early on though.
* FauxAffablyEvil: She comes across as very nice most of the time. It's probably because she's thinking about killing everyone around her.
* ForTheEvulz: She doesn't seem to have any reason for doing things other than because she loves destruction.
* FourIsDeath: And few people survive an encounter with Sekirei #04.
* GrayEyes: Signifying how cold, uncaring and dangerous she is.
* HeroKiller: The only time anyone has survived facing her was either because they managed to escape, or she lost interest in them. [[spoiler: With the one exception of Miya...]]
* IdiotHair: An ''evil'' example.
* ImplausibleFencingPowers: She can dodge bullets at close range, slice and dice with amazing precision, and stop a full charge within a second.
* KatanasAreJustBetter: Her main weapon of choice.
* LadyOfWar: An antagonistic version of this trope. And her reason for fighting is simply "to watch the world burn". [[SarcasmMode Classy...]]
* LimitBreak: Mei no Tachi - Kuon (Blade of the Underworld - Eternal Rage). [[spoiler: Her Norito is revealed to actually be quite weak, due to lacking any emotional bond with her Ashikabi.]]
* MadeOfEvil: Kaho suggests this may be her true nature.
* TheLostLenore: To Yume. [[spoiler: It's heavily implied that she doesn't love Yume because of her [[InLoveWithYourCarnage immense power]] but to her idealism.]]
* MasterSwordsman: Her primary ability as a Sekirei.
* NamesToRunAwayFromReallyFast: And the GenreSavvy people do.
* OmnicidalManiac: She wants to watch the world burn and loves killing.
* OneWomanArmy: Once left a pile of corpses for Yume to see, after slaughtering human soldiers.
* PsychoForHire: Really the one reason she's still on the Discipline Squad.
* PsychoLesbian: Obsessed with Yume, and by extension, Musubi. Further hinted at, when Natsuo talks about his deceased lover. His comments about "hating the world where the person he [[TheLostLenore loves]] no longer exists" makes her think of Yume.
* RedBaron: The Black Sekirei.
* TheRival: To Musubi (or more accurately, to Yume).
* ScarsAreForever: Hints at the existence of a scar left from [[spoiler: when she almost died at Miya's hands.]]
* SingleStrokeBattle: Dishes these out like ''candy''. [[spoiler: She was once on the receiving end of one thanks to Miya, who did it with her BARE HANDS. Karasuba recalls it fondly and wants to experience that "fear and pain" again.]]
* SlasherSmile: When she gets worked up.
* TheSocialDarwinist: Her hatred of humans is based on them being [[PunyEarthlings "weak"]]. Similarly, she once [[spoiler: tried to kill Kaho as a small child, because she considers weak Sekirei useless]].
* SuperPrototype: Due to the special adjustments given to her by Takehito.
* TrademarkFavoriteFood: She seems to be incredibly fond of apples. At one point, she brings a basket of them to Musubi and offers her one with a creepy smile.
* VillainRespect: After Kaho gave her a tough fight, where even after using her Norito, she had to turn to fighting dirty to win, she stops, looks upon Kaho and promises to never forget her name again. Now remember that the reason she forgot Kaho in the first place, is that she considered Kaho a pathetic weakling for not being able to protect herself from armed soldiers as a small child.
* WhiteHairBlackHeart: An androgynous, female example.
* WorthyOpponent: How she feels towards Yume. She wants to fight Musubi for this very reason since she posseses Yume's Tama.
* YouAreNumberSix: #04
* YouShouldHaveDiedInstead: [[spoiler: Really loses it when Yume sacrificed her Tama to save Musubi, in which Karasuba blames the latter upon the former's death. She gets over it at the beginning of the series... until the final match in which Karasuba learns the consequences of that assimilation between Musubi's and Yume's Tamas.]]
* ZettaiRyouiki: Grade A.
!!Benitsubasa #105
->'''Voiced by:''' Creator/ShizukaIto (JP), Creator/TrinaNishimura (EN, as Anita Neukar)

Known by the title of the "Red Sekirei". She has a vicious temper, as well as serious insecurities about her figure, and enjoys causing pain to her opponents. A close-combat fighter, her abilities allow her to cause massive destruction. Completely in denial of her Ashikabi's sexuality, she is often the butt of her squadmate's jokes. After the battle on the bridge, she becomes obsessed with killing Musubi.

* CureYourGays: She's convinced she can cure Natsuo with her [[ThePowerOfLove pure love]].

* EvilCounterpart: To Musubi - though they're both hand-to-hand fighters, Benitsubasa's (relative) intelligence and viciousness forms a polar opposite contrast to Musubi's ditziness and sweetness.
* EvilRedhead: Cruel, spiteful, and just plain mean.
* FlowerInHerHair: A hairclip with two flowers.
* HairTriggerTemper: Hers is even worse than Tsukiumi's, and she's definitely a lot more sadistic.
* HopelessSuitor: Utterly in denial over the fact that [[IncompatibleOrientation her Ashikabi is gay]], and will never fall in love with her.
* MurderTheHypotenuse: She's expressed the desire to murder Karasuba and Haihane, so she can have Natsuo all to herself.
* TheNicknamer: Variously refers to Musubi as "boobsy", "big breasted bimbo", "the big breasted woman" and "the girl with the pneumatic knockers".
* NoHoldsBarredBeatdown: Enjoys dishing them out to other Sekirei. Her first battle with Musubi is particularly difficult to watch, for both the characters ''and'' the audience.
* RedBaron: The Red Sekirei.
* RedOniBlueOni: The red to Haihane's blue. She's even referred to as "The Red Sekirei".

* YouAreNotAlone: [[spoiler: She declares that she will ''never'' allow Natsuo to die, making him realize the true purpose of her being assigned as his Sekirei was to show him this and help him find the will to go on living]].
* YouAreNumberSix: #105
!!Haihane #104
->'''Voiced by:''' Creator/MitsukiSaiga (JP), Clarine Harp (EN)

Known by the title of the "Blue Sekirei". She is far more laidback than Benitsubasa, and takes any opportunity to mock her over her various shortcomings. Her weapon is a pair of clawed gauntlets, and her body is covered in scars from injuring herself on multiple occasions. Unlike her partner, she is an intelligent and level-headed fighter....as well as completely aware of their Ashikabi's sexuality. She claims to simply admire his personality, but is extremely protective of him and easily flustered when he mentions kissing.

'''Ashikabi:''' Natsuo Ichinomiya

* AmusingInjuries: Prone to these.
* BadassDecay: [[InvokedTrope Invoked]] in the second phase along with Benitsubasa.

* CantHoldHerLiquor: Gets totally shitfaced just from inhaling the fumes from alcohol, let alone actually drinking.
* CombatPragmatist: Not above cheap shots or cheating to win.

* CreepyShadowedUndereyes: Usually shadowed further by her hair.
* DeadpanSnarker: A fountain of snark, especially concerning Benitsubasa.

* HighPressureBlood: Whenever she's injured.
* IronicFear: Afraid of heights. When questioned by Benitsubasa, she claims to only remember her phobia when not fighting.
* [[LoadBearingHero Load-Bearing Villain]]: Shields Natsuo from a collapsing building, and cheerfully states that she protected him.....while bleeding profusely.
* NoodleIncident: We never find out how she obtained the extensive scars all across her body.
* NonStandardCharacterDesign: Her beady and tired-looking eyes make her stand out when alongside the other Sekirei, and cause her to look creepy and ([[HollywoodHomely comparatively]]) less attractive.
* OnlySaneWoman: In spite of her creepiness, she is actually the most emotionally stable and sensible of Natsuo's Sekirei.
* PerkyGoth: Though creepy looking, she's actually laid back and comical.

* WolverineClaws: Her clawed gauntlets.
* YouAreNumberSix: #104

With their own private military force and the Discipline Squad, the company has almost unlimited resources and command of the city. It oversees the care and maintence of the Sekirei, as well as forcing them to participate in the Sekirei Plan.

* CheshireCatGrin: Sports one often.

Mikogami remains completely unrepentant, only realizing that she hates him but utterly refusing to admit he was wrong.

It took Minato restraining her to keep Tsukiumi from blasting Takami through a wall with water pressure.
* YearsTooEarly: When Minato calls her out, she captures him and tells him that he's ''100 years'' too early to do that.

He was the adjuster of the first generation Disciplinary Squad ([[spoiler: Miya]], Matsu, Kazehana, Karasuba, and Mutsu), Homura, Uzume, Hikari, and Hibiki. After witnessing the destructive power of the first generation, he comes to doubt the intentions of Minaka and the change of the S-Plan from scientific study to a battle royale. He eventually comes to oppose the Sekirei Plan, but died [[spoiler: stopping an out-of-control Jinki]] and was never to see his plans through. Seo was given an unspecified task by him, and Miya continues to carry on his will.

[[folder: The Southern Territory]]

!!Hayato Mikogami
->'''Voiced by:''' Creator/JunFukuyama (JP), Creator/ToddHaberkorn (EN)

The Ashikabi of the South. A wealthy and spoiled teenager, he is known as a [[TheCollector collector of Sekirei]] and aggressively pursues any target that catches his interest. While extremely cunning and ruthless, he is also very childish and treats the Sekirei Plan like a very exciting game rather than a serious life-and-death conflict. Because of this, he tends to stick to the rules and will step in to prevent others from cheating.

'''Sekirei:''' Mutsu, Akitsu, Yomi, Mitsuha, Mitsuki, Taki, Himeko, Juusa, and Momo

* AbductionIsLove: Infamous for aggressively pursuing Sekirei, and [[DoesThisRemindYouOfAnything forcefully]] winging them. It's unclear how many of his Sekirei were victims, but the trope is played straight in that they all seem genuinely fond of him.
* AbusiveParents: Possibly, in that they're stated to be [[ControlFreak extremely controlling]] and threatened to send him off to live alone on the other side of the planet ''again'' if he misbehaves a second time.
* AdoptTheDog: Invoked in-universe with his relationship with Mutsu, as he's explicitly compared to an "abandoned dog" that Mutsu picked up. In turn, his relationship with Akitsu is one big PetTheDog moment.
* AffectionateNickname: "Miko-sama", by most of his Sekirei.
* AmbiguouslyBi: Ignores his harem of [[BuxomIsBetter attractive]] female Sekirei, but expresses interest in whether the male one will react if "[[DoubleEntendre kissed]] [[FemaleGaze anywhere else]]".
* AntiVillain: His later development makes him into a Type II, in contrast to his first appearance.
* AscendedFanboy: An avid gamer playing a real life game! He's the only one thrilled whenever [[BigBad Minaka]] announces some new rule or twist.
* AttentionDeficitOohShiny: His Sekirei note his tendency to be easily distracted by anything new, interesting, or rare.
* BenevolentBoss: Of the AffablyEvil variety, if [[RunningGag Hikari's complaints]] about his Sekirei are anything to go by. [[spoiler: Turns out to be true, as his response to Mitsuha's termination is to immediately fret over Akitsu and then order everyone to be careful.]]
* BigFancyHouse: A western-styled mansion, filled with his collection of PrettyFreeloaders.
* {{Bishonen}}: Hikari and Hibiki even comment on his looks, as one of the ''many'' things about the Southern Sekirei that make them jealous.
* BlitheSpirit: His stated intention if he were to win, as he considers the world too restricting and unexciting.
* BrattyHalfPint: He's much younger than the other Ashikabi, and seems to actively attempt to get on their nerves.

* BreakTheHaughty: [[spoiler: He goes into his match with Sanada confident, but quickly finds himself helplessly watching his Sekirei get slaughtered in rapid succession]].

* EvenEvilHasStandards: Expresses disgust at how Higa treats his Sekirei like disposable things, and wonders if he actually ''hates'' them.
* FairPlayVillain: Generally, he considers it important to stick to the rules of the Sekirei Plan. This brings him into direct opposition with the East, since Higa continually [[LoopHoleAbuse cheats]].
* FreudianExcuse: His relationship with his parents is....poor at best. His parents' treatment made him feel like he had no control over his own life, leaving him deeply resentful of the world and terrified of further abandonment. As a result, he calls his defeated Sekirei "useless" and claims to hate them, since they abandoned him.
* GottaCatchThemAll: Approaches the Sekirei Plan like a game of Pokemon.
-->'''Mikogami''': ''It's a natural element! It's fire! It's rare! I want one!''
* HatesBeingAlone: So he's filled his home with as many Sekirei as possible.
* HiddenDepths: Easily one of the most complex characters in the series.

* JumpedAtTheCall: He's an enthusiastic participant in the Sekirei Plan, having ''finally'' gotten the chance to live a more exciting life.
* KarmaHoudiniWarranty: He seems to have escaped punishment for the attack on Takami, possibly because this allowed the "Green Girl" game to occur. However, his karma eventually does catches up to him later on. [[spoiler: Sanada's ''real'' AmazonBrigade slaughter almost all his Sekirei in a matter of moments, with Akitsu sacrificing herself to defeat them]].
* {{Keet}}: Veers into this on occasion, especially when something exciting happens.

* MoralMyopia: He's not above crossing lines to get what he wants, such as attacking other Ashikabi in his quest to obtain a new Sekirei. However, he reacts poorly to slights against him, even ordering Mutsu to take care of Yukari after she hits him.
* NiceJobBreakingItHero: "''I broke the ship!''" [[spoiler: The ship was damaged during his match against Sanada, allowing a military force to launch an invasion of Kamikura Island]].
* NonActionGuy: He ''claims'' to know "self-defense". He doesn't.
* OffToBoardingSchool: It's mentioned that his parents punished him for acting up in the past by sending him to [[DisproportionateRetribution live by himself]] in America for a while. This seems to have been their version of grounding him.

* PleaseDontLeaveMe: While hanging on to Mutsu's ScarfOfAsskicking.

* PuppyDogEyes: Described by Mutsu as his "abandoned dog" expression. It is super-effective against him.
* TheRedBaron: "Mikogami of the South", in acknowledgement of his control of the southern portion of the city.
* TheRival: While all of the Ashikabi are in competition with each other, he tends to be Minato's most direct and consistent opponent. He also possesses a fairly strong moral code and is willing to work alongside Minato in more dangerous situations, making the two of them have a much more cordial relationship compared to most other Ashikabi.
* RescueRomance: Mutsu rescued him from a violent mugging, though the "romance" part is still [[HoYay unclear]].
* RichBoredom: Expresses that he hated his dull and uneventful life, prior to joining the Sekirei Plan.
* SensitiveGuyAndManlyMan: The Sensitive Guy to Mutsu's Manly Man.
* ShooTheDog: To Akitsu, telling her that since she's not really his Sekirei, she doesn't have to fight for him anymore. While she initially fears that she's being discarded again, he makes it clear that isn't the case.
* SpoiledBrat: The "lavished with material goods in place of affection" variant.

* WalkingTheEarth: In chapter 184, he winds up searching the world for clues about Sekirei, joined by a large group of his own Sekirei. He is shown to be happier than ever, as he gets to live out his dreams of adventure.

->'''Voiced by:''' Daisuke Matsubara (JP), Creator/RobertMcCollum (EN)

A reserved and [[StraightMan serious]] swordsman, as well as one of the few male Sekirei. He is one of the founding members of the Discipline Squad, and now serves as the bodyguard for the Ashikabi of the South, Mikogami. More often than not, he serves as a VoiceOfReason and attempts to keep his master out of harm's way, a duty that has thus far kept him out of battle. He is noted by his former allies as being a difficult person to get to know, but is deeply devoted to his young master and turns out to be surprisingly kind, even to his enemies.

'''Ashikabi:''' Hayato Mikogami

* AbsoluteCleavage: A male example.
* AdoptTheDog: An in-universe example: [[spoiler: Miya]] expresses surprise at him settling down after being emerged. Mutsu even describes it as losing to Mikogami's "abandoned puppy" expression.
* TheAgeless: Appears the same age as most Sekirei, but he was fully grown when even Homura was still an infant.
* AloofAlly: Veers into this when interacting with the original Disciplinary Squad.
* {{Bishonen}}: Tall, handsome, thin as a rail.

* IfItsYouItsOkay: Implied. He states he would have preferred to be emerged by a "pretty lady", but accepts that Mikogami is the one that [[RedStringOfFate called him]].
* KatanasAreJustBetter: Though he rarely draws it, using the scabbard instead.
* KnowWhenToFoldEm: Usually by carrying Mikogami off before he can do something foolish.
* LeanAndMean: Subverted. A tall, thin antagonist in black.....who turns out to be a pretty nice guy without any malicious intentions. He, along with Akitsu, are the only Southern Sekirei that aren't {{Jerkass}}es.
* [[MagicalGirlfriend Magical Boyfriend]]: Answered Mikogami's wish to meet someone amazing.
* MasterSwordsman: Though he rarely draws it, the anime shows him to be able to take on Karasuba and live.
* MrFanservice: ArtEvolution has resulted in greater focus being given to just how low his shirt hangs open, and how chiseled his abs are.

* SuperPrototype: Due to the special adjustments given to him by Takehito.

* WithFriendsLikeThese: Towards Matsu and Kazehana. He has ''several'' unflattering nicknames for them.
* WouldntHitAGirl: He states he's got no interest in killing girls. This ''would'' put him at a serious disadvantage, since almost all Sekirei are female......but his strength means he rarely has to fight seriously.

* HoistByHerOwnPetard: Using metal wires to fight Sekirei with [[ShockAndAwe lightning]] powers? Not smart.
* {{Jerkass}}: She runs her mouth quite a bit, insulting people left and right.
* MiniDressOfPower: A black and yellow one.
* RazorFloss: Her primary weapon.
* RichBitch: Spoiled and rude as hell.
* YouAreNumberSix: #39
* ZettaiRyouiki: Type A.

%%* CombatStilettos
* DangerouslyShortSkirt: It.....barely counts as one.
* MysteriousMist: Her power allows her to generate it.
* MysticalWhiteHair: An elemental-type Sekirei. Her hair notably resembles her element.
* RapunzelHair: Long and flowing past her waist.
* WomanInWhite: White hair, white clothing, and mist-based powers. She's got the mysterious look down perfectly.

'''Ashikabi:''' Hayato Mikogami

* BitchInSheepsClothing: May be one, expressing sympathy for her pathetic, poverty-stricken opponents while promising to kill them.
* CuteAndPsycho: She's genuinely cute, and cares about her comrades. But she's ''also'' thrilled at the idea of slicing up her foes.
* DefeatByModesty: Just ''barely'' avoided, as Kuzuri wasn't fighting seriously at the time.
* DefiledForever: Absolutely horrified that someone saw [[PantyShot her panties]] before Mikogami.

[[folder: Eastern Territory]]

!!Izumi Higa
->'''Voiced by:''' Takuma Takewaka (Season 1), Creator/JunichiSuwabe (Season 2) (JP), Creator/JerryJewell (EN)

The Ashikabi of the East, and the head of a powerful pharmaceutical company. He is extremely ambitious, cunning, and ruthless to the point that he treats his own Sekirei as disposable tools. Using his influence, he blackmails Uzume into serving him and bribes other Ashikabi into serving him. He opposes the Sekirei Plan, and seeks to undermine [[MegaCorp MBI's]] authority.

'''Sekirei:''' Toyotama, Ichiya, Oriha, Katsuragi, Shi, Sai, Kaie, Oshino, Kujou, Kaiha, and two unnamed.

* AbductionIsLove: He is one of the Ashikabi that [[DoesThisRemindYouOfAnything forcefully]] wings Sekirei, though he makes it clear love isn't even on the table. He also [[spoiler: kidnaps Yukari and intends to marry her]]. It [[{{Understatement}} doesn't]] work out as he'd planned.
* AmbitionIsEvil: He's by far the most ambitious character, and [[KickTheDog kicks many a dog]] along the way towards his goal.
* AndNowYouMustMarryMe: [[spoiler: Holds Yukari hostage, while proposing marriage to her. It is, of course, all a plot to take advantage of who her parents are.]]
* AppealToForce Prompted by Mikogami's [[TheReasonYouSuckSpeech harsh advice]], uses his Sekirei to perform a hostile takeover of his family's company.
-->'''Higa:''' ''I'm taking over this company by force. Tell that to the old farts. From now on, I do as I want.''
* ArmorPiercingQuestion: Receives several from Mikogami during his TheReasonYouSuckSpeech. It forces him to completely re-evaluate his methods and leads to a PetTheDog moment and the hostile takeover of his company.
* BadBoss: Treats his Sekirei as {{Mooks}}, making it clear that they are completely disposable to him. [[spoiler: Toyotama's defeat seems to have made him finally realize his failings as an Ashikabi.]]
* {{Bishonen}}: According to Yukari.
* BodyguardBabes: Toyotama and Ichiya often act as his bodyguards.
* ConsummateLiar: Deception is one of his favorite tools, and he plays his various pawns like fiddles.
* CorporateWarfare: His company is TheRival to the primary company, and counters their actual private army with an army of Sekirei.
* CorruptCorporateExecutive: To the t.
* DiabolicalMastermind: He tries to be this, but is ultimately out-witted by various parties.
* FauxAffablyEvil: He usually introduces himself in a very polite manner, often seeming like a reasonable and friendly individual. But he quickly drops this, in favor of showing just how ruthless and cruel he can be.
* GracefulLoser: Implied, surprisingly enough. While he doesn't have any lines in the final chapters, he seemingly abandons all thoughts of vengeance against Minato, and seemingly starts running his company honestly and above board.
* GreenEyedMonster: [[spoiler: He greatly resents Minato, convinced that the other has benefited so much from his father's position as Gamemaster. Even when he learns Minato was unaware of his father's identity and obtained everything through his own efforts, he actually hates him more]].
* HostageSituation: Concocts two different ones to force Sekirei to do his bidding.
* HumiliationConga: Goes into a board meeting. Comes out to learn [[spoiler: four of his Sekirei have been terminated, his hostage has been rescued, his blackmailed assassin has been terminated, and to top it off? The girl he'd kidnapped with the intention of forcing her to marry him has set fire to his penthouse before escaping.]] He's understandably less than pleased by the news.
* IWillFindYou: [[spoiler: Promises a defeated Toyotama that he will come for her someday, and asks her to wait for him.]]
* {{Jerkass}}: Readily uses other people to accomplish his own goals, using Chiho's life to force Uzume to do his bidding and subjecting his own Sekirei to all manner of emotional abuse.
%%* LastNameBasis
* LoopholeAbuse: During the 3rd Phase of the Sekirei plan when he brings in more Sekirei and claims it's not breaking the rules so long as they don't fight.
* MagneticHero: A villainous example. He regularly recruits other Ashikabi, often through his claimed goal of ending the Sekirei Plan and allowing all his followers to remain with their Sekirei. He's.....telling the truth about the first part, at least.
* ManInWhite: Prefers a nicely tailored suit in various shades of white and cream.
* ManipulativeBastard: What he does to poor Uzume and then to Shiina.
* ManOfWealthAndTaste: Oh, so very much. He's got the nice suit, the penthouse apartment, and the CoolCar to prove how wealthy he is.
* MeddlingParents: His family, as the senior board members of his company, ''constantly'' get in his way. This comes to a head when he's dragged into a meeting with them, and comes out to a HumiliationConga. He's beyond furious and declares his intention to kill them all someday.
* NonActionGuy: Implied to ''not'' be the case, surprisingly enough. Upon witnessing Seo and Sanada's BigBallOfViolence, he remarks that it's a good thing he took up boxing.
* AnOfferYouCantRefuse: At least two of the Sekirei under his command were there because of him [[HostageSituation using their Ashikabi]] as leverage.
* PetTheDog: [[spoiler: His heartfelt apology to a defeated Toyotama for being a BadBoss.]]
* TheRedBaron: "Higa of the East", since he holds control over the Eastern portion of the city.
* RevengeBeforeReason: Comes dangerously close in his grudge against Minato, losing an enormous amount of his Sekirei and much of his influence within the Game as a direct result.
* SharpDressedMan: His tailored suits and obvious fashion sense make him stand out from other Ashikabi.
* SmugSnake: Oh, so very much. He's the smuggest of the smug, but quickly loses his cool if things don't go his way.
* TheSociopath: He shows most of the traits of this, at least early in the story. His attachment to everyone, except ''maybe'' his subordinate Kakizaki is purely a facade, at best, and he sees absolutely nothing wrong with any criminal or outright abhorrent behavior, so long as he doesn't actually face any consequences, and ''if he does'' it's always [[NeverMyFault because of someone else]] [[MurderIsTheBestSolution who has to die]]. To wit, he has engaged in kidnapping, outright assault, assassination by proxy, hostage taking, threatening the life of an invalid in his hospital, with whom he had a prior legally binding contract for treatment, has actually engaged in murder (of his own company's board of directors and employees), attempted to murder both Minato and Natsuo using MBI's Kill Sat, and treated his Sekirei, who are strongly implied to be with him against their will as nothing more than expendable pawns, regretting their termination only because it inconveniences him, and absolutely throws a murderous fit when things don't go his way, even if it's a direct result of his own actions.
* TookALevelInKindness: The epilogue reveals that [[spoiler: he chose to allow almost all of his Sekirei to refuse being winged by him again, allowing for the ones that he forcefully winged to live their lives free of the memories of their time as his slaves while also allowing the ones most loyal to him faithfully stay by his side.]]
* VillainousBreakdown: The cracks are definitely showing in his cool exterior, and at this point he's lost much of his former bite.
* VillainousDemotivator: His Sekirei know they have ''two'' options: Victory or termination. Several have mentioned being told they couldn't come back unless they were successful.
* VillainousFriendship: Type 1. Kakizaki describes himself as Higa's OnlyFriend and states the two have been good friends for many years.
* WeHaveReserves: Tends to throw his Sekirei into battle, and makes it clear that he has no more use for them if they can't win.
* XanatosGambit: His participation in the 3rd Match, as if he managed to win he got a second Jinki. And if he lost, he still [[spoiler: only sacrificed his weaker Sekirei while gaining valuable information about his opponents ''and'' could still have Uzume steal the Jinki from the winner afterwards. When Uzume was intercepted, he still benefited by being able to order her to lead a direct attack on Maison Izumo]]. However, things eventually derail after a combination of TheDogBitesBack, the dropping of the DistressBall, Mikogami's [[EnemyMine interference]], and Minato running his own gambit. Cue his VillainousBreakdown.

* IWillWaitForYou: [[spoiler: In reponse to Higa's promise to come and reclaim her from MBI someday.]]

* BladeBelowTheShoulder: Her weapons are two massive blades, that rip out from her billowing sleeves when in use.

%%* OperaGloves

->'''Voiced by:''' Kenji Takahashi (JN), Creator/EricVale (EN)

Higa's personal secretary, and longtime friend.

'''Sekirei:''' Kochou

* ConsummateProfessional: Handles himself with utter professionalism, even in the midst of a Sekirei battle.
* TheDragon: Higa's secretary, and the field handler for all his Sekirei.
* FauxAffablyEvil: He's completely professional, but just as much of a jerk as his employer.
* TheHandler: To Uzume, and all the other Sekirei working for Higa.
* MoralDissonance: (Actually legal dissonance) Knowing he's an accomplice to aggravated kidnapping, and illegal imprisonment (both felonies) his immediate response upon seeing Higa's penthouse on fire is to rebuke Yukari "You set the fire, didn't you? That is a crime, you know." She immediately calls him out on it.
* NonActionGuy: Along with his Sekirei, who is an EvilCounterPart to Matsu.
* OhCrap: Has a rather large one when his usual SmugSnake tactics don't work on Yukari, and she breaks the plate-glass penthouse window before jumping out.
* OnlyFriend: To Higa.
* PragmaticVillainy: To the core, he's a pragmatist willing to take whatever measures are necessary.
* SharpDressedMan: In line with being a true professional.
* SmugSnake: Seems his greatest joy in life is (as handler) to openly torment those already under Higa's heel. Case in point, telling a distressed Uzume "you don't have much time left" regarding Chiho's health, and he does so with a cruel smile.
* TheSociopath: In a legal sense, he could be considered "better" than Higa as a court of law could only find him culpable as an accomplice to kidnapping and illegal imprisonment of Yukari, and even that is questionable considering Japan's customs, but on an interpersonal level, it could be argued that he's less functional than Higa. To wit, while Higa's ruthless cruelty does have something to gain, Kakizaki's only goal in his actions is his own personal enjoyment. He interrupted Uzume's time with Chiho purely to tell the former that she "doesn't have much time left" to make Uzume suffer, outright cheered when Higa pushed Shiina over the despair event horizon by making the latter think that Yukari preferred humans over Sekirei, when he saw Minato trying to talk down Homura from self-destructing, actually tried to intervene to keep Minato from succeeding, and his only concern when Yukari escaped was not her well being, but the fact that Higa would be upset with him, and lastly, if Higa shows any signs of lucidity or growing a conscience, Kakizaki immediately talks him out of it.
--> Higa: "Sometimes, being an adult makes me feel dirty."
--> Kakizaki: "You should never say that about yourself."
* StoicSpectacles: Calm and composed, at least when he's not directly in the line of fire.
* VillainousFriendship: Type 1, as it seems he and Higa are genuinely good friends that care for the others well being.

!!Kochou #22
->'''Voiced by:''' Akiko Tanaka (JP), Creator/WendyPowell (EN)

A calm and composed woman with the ability to access machines. She is allied with the Eastern Sekirei, and serves Higa alongside her Ashikabi.

'''Ashikabi:''' Kakizaki

* TheComicallySerious: She lectures Matsu about using a cell phone in a hospital......ignoring that there's two enemy Sekirei running past her.
* EvilCounterpart: To Matsu -- a cool and collected Brain-type that maintains a professional air no matter the circumstances.
* MissionControl: For the Eastern Sekirei.
* NervesOfSteel: Unflinching and professional, even in the presence of two enemy Sekirei. Tsukiumi is duly impressed.
* SexySecretary: To her Ashikabi and as a result, to Higa.
* StoicSpectacles: A female variant.
* {{Technopath}}: Just like Matsu, allowing her to spy on computers.
* YouAreNumberSix: #22


[[folder: Western Territory]]

!!Sanada Nishi
->'''Voiced by:''' Creator/KisshoTaniyama (JP), Charles Baker (EN)

The Ashikabi of the West. Though a hot-tempered and violent biker, he is actually a good person that deeply cares for his trio of Sekirei. After befriending Seo, he is convinced to become another of Minato's ally and supports him during the 4th match. He is something of a pervert, and seems to develop a crush on almost every woman he meets.

'''Sekirei:''' Kuzuri, Kujika, Shijime, Chiyo, Yuna, and Hatae

* AmazonBrigade: The South and East Ashikabi each had a dozen or more Sekirei under their command. Minato has six, almost all of which are Single Numbers. And Sanada, the fourth Ashikabi that controls territory in the city? He's got ''three'', but is still considered a threat by the others. [[spoiler: This is because he actually has ''six'' Sekirei, and his concealed Sekirei are ruthless and powerful low-digits]].
* AmazonChaser: Thinks Miya's strength makes her even ''more'' attractive.
* AmusingInjuries: Prone to these almost as much as Seo.
* BadassBiker: Pretty much his thing.
* BadassNormal: He fights right alongside his Sekirei.
* BalancedHarem: His Lovelies! He showers them equally with affection, and it's clear all equally care for each other.
* BattleHarem: His trio of Sekirei.
* {{Bishonen}}: In a manly kind of way.
* BoisterousBruiser: Rather loud but tough in a fight.
* ChivalrousPervert: He's much like Seo in this regard.
* ComedicSociopathy: Again like Seo since their violence is often PlayedForLaughs.
* DefeatMeansFriendship: Becomes good friends with Seo once they finish beating the crap out of each other.
* GoodOldFisticuffs: Gets into a lot of fist fights. Start a major brawl in the anime to help Minato out.
* HellBentForLeather: His jacket and pants.
* HopelessSuitor: Considers Miya's [[TheMourningAfter devotion]] to her husband a bonus, rather than a negative.
* HotBlooded: The hottest of all! He shouts, throws punches, and emotes with the best of them.
* IAmNotLeftHanded: [[spoiler: In his battle against Mikogami, he reveals that he actually has ''six'' Sekirei. His real AmazonBrigade proceed to tear through most of Mikogami's Sekirei in moments, and are strong enough to prove a challenge to Single Numbers like Mutsu and Akitsu]].
* IdiotsCannotCatchColds: He proudly declares that he's never caught a cold. Mikogami thinks this makes perfect sense, pointing out the belief about idiots being immune to colds. Sanada...is less than amused.
* JerkWithAHeartOfGold: He may seem like a thug, but he's actually a pretty decent guy. At least, if you don't accidentally piss him off.
* LeeroyJenkins: Unlike Seo, his general strategy seems to be limited to "jump into battle and hit things". Because most Ashikabi are {{Non Action Guy}}s, this usually works out for him.
* LikesOlderWomen: THRILLED when he learns Miya is a "beautiful, older woman".
* MeaningfulName: Lampshaded, since "Nishi" means "West".
* MrFanservice: Bare chested and in leather.
* PipePain: Wields a section of metal pipe as a weapon.
* TheRedBaron: "Sanada of the West", which leads to confusion when he introduces himself.
* RomancingTheWidow: Even more thrilled when he learns Miya is a widow.


!!Shijime #106, Kuzuri, and Kujika
->'''Voiced by:''' Creator/LindsaySeidel (EN; Shijime), Madeleine Broseh (EN; Kuzuri), Hilary Couch (EN; Kujika)

The West's trio of Sekirei. They behave in an extremely childish manner, but their strength has allowed him to claim the Western portion of the city as his territory.

'''Ashikabi:''' Sanada Nishi

* AmazonBrigade: Strong enough to secure Sanada's place as one of the top four Ashikabi, with the smallest group.
* AmbiguouslyBrown: Kuzuri
* AnnoyingYoungerSibling: Shijime behaves like this, much to Benitsubasa's frustration and Haihane's amusement. That's right, her big sisters are the ''Discipline Squad''.
* BadassAdorable: They're absolutely adorable, and also enjoy a good fight.
* BlushSticker: Shijime and Kuzuri
* ByThePowerOfGreyskull:
** Shijime: ''These are the sleeves of my pledge, smash and clear the wall before my Ashikabi.''
** Kuzuri: ''These are the heels of my pledge, smash and clear the wall before my Ashikabi.''
** Kujika: ''These are the elbows of my pledge, smash and clear the wall before my Ashikabi.''
* ClothingCombat: Shijime's Norito implies her sleeves are her weapon. Kuzuri also uses the pair of straps hanging from her top to parry attacks, showing they are strong enough to withstand blows from another Sekirei's sword.
* CloudCuckooLander: They're constantly off in their own world, and rarely see the seriousness of a situation.
* CombatStilettos: Kujika
* DarkSkinnedBlond: Kujika
* GenkiGirl: All three are super-perky!
* GlowingEyesOfDoom: Parodied, when they use their Norito.

* HellBentForLeather: Kuzuri and Kujika.
* HitAndRunTactics: Noted to be incredibly fast, even by Sekirei standards.
* PowerTrio: They're never away from each other for long, always operating as a team.
* {{Stripperiffic}}: Kuzuri and Kujika.
* TechnicalPacifist: [[spoiler: Sanada reveals they never fight to win, instead simply wanting to play and have some fun. As such, he relies on his deranged Sekirei to win the actual battles]].
* TokenMiniMoe: Shijime
* UnderBoobs: Kuzuri
* YouAreNumberSix: Shijime is #106. Kuzuri and Kujika's numbers are still unrevealed.

!!Chiyo #14, Yuuna #17, Hatae #20

A trio of blood-thirsty Sekirei, barely under the control of their Ashikabi. They take great pleasure in slaughtering their opponents.

'''Ashikabi:''' Sanada Nishi

* AmazonBrigade: [[spoiler: The ''real'' reason Sanada became ruler of the Western territory]].
* AmbiguouslyBrown: Hatae
* AxCrazy: To the extent even their own Ashikabi fears them.
* BladeBelowTheShoulder: Hatae
* BloodIsTheNewBlack: Their Ashikabi points out that they're covered in blood, having just finished off several opponents.
* BloodKnight: They're excited when they finally find a stronger opponent in [[spoiler: Akitsu]].
* LeanAndMean: All three are reed-thin, moreso than most Sekirei. And so vicious even their Ashikabi finds them frightening.
* NiceJobFixingItVillain: [[spoiler: Not only does Akitsu ''not'' react well to her comrades being slaughtered, but their vicious actions are the push necessary to allow her to finally be emerged]].
* SinisterScythe: Chiyo
* SlasherSmile: All three of them constantly sport deranged grins while dishing out suffering.
* {{Stripperiffic}}: Incredibly so.
* WhipItGood: Yuuna
* YouAreNumberSix: #14, #17 and #20.

[[folder: Ashikabi]]

Humans with a special genetic trait that allows them to bond with Sekirei, a process known as "Winging".

* BlessedWithSuck: Having a beautiful MagicalGirlfriend? Awesome. Having to watch her fight to the death against another MagicalGirlfriend, knowing the odds are stacked against you and losing means never seeing her again? Yeah, not so awesome. Little surprise that most Ashikabi are desperate to escape the Sekirei Plan.
* BoyMeetsGirl: A core element of the series.
* DesperatelyLookingForAPurposeInLife: Many Ashikabi experienced this in some form, prior to encountering their Sekirei. Minato and Haruka were both losers unable to find their place in the world, while Oosumi and Mikogami both experienced extreme boredom and acted out in an effort to fill that missing something. All Ashikabi find their purpose, and tend to undergo significant changes as people once bonding with their Sekirei.
* DevotedToYou: Sekirei are naturally devoted to their Ashikabi, to one degree or another.
* HalfHumanHybrid: Modern Ashikabi are the descendents of ancient Sekirei and their human masters, and are as a result not completely human.
* IDidntMeanToTurnYouOn: A Sekirei reacting to them tends to get.....''excited''. It makes for an interesting first impression.
* InterspeciesRomance: Almost all bonds are explicitly romantic in nature, and Sekirei often refer to their Ashikabi as their spouse.
* AMagicContractComesWithAKiss: This is how they wing their Sekirei.
* MagicContractRomance: The majority of bonds are exactly this.
* MagicKiss: Their main role in a battle is providing the kiss a Sekirei needs to activate their Norito.
* MeetCute: The standard way Sekirei and Ashikabi meet.
* NonActionGuy: The vast majority of Ashikabi are just normal people. Seo and Sanada are the exceptions, and readily ignore that whole "no Ashikabi fighting" rule.
* PunyEarthlings: Natsuo points out just ''how'' vulnerable Ashikabi are during a Sekirei battle, and how easy it would be for one to be killed by accident if they were in the wrong spot at the wrong time.
* RedStringOfFate: Each Sekirei has a destined Ashikabi, that they are meant to be with. Powerful Ashikabi are capable of attracting [[BattleHarem multiple]] Sekirei.

!!Kaoru Seo
->'''Voiced by:''' Creator/KatsuyukiKonishi (JP), Creator/IanSinclair (EN)

The first Ashikabi that Minato encounters, Seo is a shady but kind-hearted man that becomes one of his most vital allies. His Sekirei are the twins Hikari and Hibiki, and he was once the best friend of the deceased scientist, Takehito Asama. This friendship allowed him to learn many secrets about the Sekirei, and also granted him a special ability that allows him to weaken enemy Sekirei.

'''Sekirei:''' Hikari and Hibiki

* AmusingInjuries: Seo always getting hurt by his Sekirei is usually PlayedForLaughs.
* BabiesEverAfter: [[spoiler: He winds up making four babies, all boys, with Hikari and Hibiki.]]
* BadassNormal: He's one of the few Ashikabi to get involved in the action, and can hold his own pretty well.

* {{Bishonen}}: Handsome, beneath all his scruff and bad attitude.
* BrilliantButLazy: To the absolute core.
* BromanticFoil: To Minato. He's a much more openly-perverted guy who is explicitly in a sexual relationship with both of his Sekirei, whereas Minato is a more CovertPervert who intentionally resists entering into such relationships with his own Sekirei.
* ButtMonkey: To Hikari and Hibiki. [[spoiler: And his four kids who also have electric powers.]]
* CasanovaWannabe: Of course Hikari and Hibiki just won't let him.
* ComeBackToBedHoney: Attempts this on Hikari. She responds by electrocuting him.
* ComedicSociopathy: His shady antics are typically played for comedy, such as stating he's going to substitute a random cat for one he was hired to find.
* ChivalrousPervert: At least, he ''tries'' to be.
* DeadpanSnarker: He's rarely phased by things, responding with sarcasm and snark.
* DefeatMeansFriendship: Once the fists stop flying, he forms a strong friendship with Sanada.
* HarmlessElectrocution: Near constantly. [[spoiler: If it isn't Hikari and Hibiki, it's his four sons.]]
* HiddenHeartOfGold: Beneath his tough exterior, he's actually.....a pretty decent guy, and becomes one of Minato's most important allies.
* HouseHusband: Surprisingly enough. Before Miya got the hang of married life, he was the one that handled all the domestic stuff for Takehito. Miya teasingly refers to him as an "adulterer" for keeping house for her husband.
* JerkWithAHeartOfGold: He can be a jerk at times, but he's also a good friend and ally to have.
* LastNameBasis: Almost always referred to as Seo by every other character.
* MrFanservice: Moreso than any other Ashikabi, he's often seen wearing a tight tank top and even has a couple shirtless scenes.
* PerpetualPoverty: He and his Sekirei are seen working but still never have enough to feed themselves consistently.
* PowerNullifier: His 'Matsurou Ashikabi' ability given to him by Takehito.
* TheRedBaron: "Worst Ashikabi"
* SensitiveGuyAndManlyMan: The manly man to Minato's sensitive guy.
* TheStrategist: He formulates the plan to help Kuno and Haruka escape the city. He also helped Minato to find Kusano when she first appeared. And in the end of Season 2, he's hired by Higa to break into MBI's headquarters and steal their company secrets.
* SupremeChef: Really! He's the one that taught Miya how to cook.
* TallDarkAndSnarky: Check, check, and check.
* ThanksForTheMammary: Unlike Minato, he always does this on purpose and often gets zapped for it.
* TwinThreesomeFantasy: Proudly declares he was late to the 4th Match because the twins "kept him up all night". The embarrassed reaction from the twins and Hibiki's pleas about children being present suggests he wasn't making it up. [[spoiler: It's more or less confirmed at the finale when it's revealed that his four sons were all born on the same day.]]

!!Yukari Sahashi
->'''Voiced by:''' Creator/KanaAsumi (JP), Creator/BrinaPalencia (EN)

Minato's younger sister, a cheerful but violent girl obsessed with pretty boys. After becoming Shiina's Ashikabi, she promises to help him find Kusano and hunts other Ashikabi looking for information. This leads to her earning the title of the "Devil Ashikabi", making her something of an urban legend feared by other pairs.

'''Sekirei:''' Shiina

* DangerouslyShortSkirt: Though as she doesn't directly involve herself in action very frequently, she doesn't suffer from it nearly as much as Tsukiumi does from hers.

* GlowingEyesOfDoom: She is often seen with these, and she is just as scary as Miya.
* GroinAttack: Her standard approach to men that piss her off.
* HostageSituation: Ends up in one, with Higa using her to control Shiina.
* InnocentCohabitation: Surprisingly enough, with Shiina.
* JerkWithAHeartOfGold: While she's brutal towards her enemies, she's generally kind and empathetic towards her allies and civilians.
* LovableSexManiac: She's pretty open about her interest in attractive people, and will go so far as to grope other women as a greeting.
* MadScientistsBeautifulDaughter: Higa made the mistake of thinking she was this. ''Boy'', did he get that one wrong. She sets fire to his penthouse on her way out.
* MasculineGirlFeminineBoy: The masculine girl to both Minato and Shiina's feminine boys.
* NamesToRunAwayFromReallyFast: Being called the Devil Ashikabi discourages anyone from messing with her.

* SiblingYinYang: She's outgoing and confident, but also incredibly ruthless and indifferent to those she considers to be her enemies, whereas Minato is timid and passive, but also an AllLovingHero who wants everyone involved in the Sekirei Plan to have a happy ending regardless of their allegiances.
* SkinshipGrope: She's often trying to cop feels on the big breasted women running around.
* SlasherSmile: Probably one reason why she earned her nickname.
* ViolenceIsTheOnlyOption: How she gained the title of "Devil Ashikabi".
* WifeBasherBasher: Ruthlessly deals with anyone that makes girls cry, which leads to hilarity when she [[spoiler: mistakenly believes Minato was mistreating Kusano and kicks him across the room, then threatens to kill him]].
* ZettaiRyouiki: Type A.

* YouAreNumberSix: #95
* ZettaiRyouiki: A type B.
