Minato Sahashi is an [[OrdinaryHighSchoolStudent Ordinary College Student]], even though he's failed his entrance exams twice. As he's walking down the street, he suddenly finds a MagicalGirlfriend falling from the sky and [[CrashIntoHello crashing into him]]. She is Musubi, one of [[OneHundredAndEight 108]] beings known as Sekirei, about to be engaged in a [[ThereCanBeOnlyOne Battle Royale]] across Tokyo, headed by the mysterious MBI organization. With a kiss, Minato "wings" Musubi and becomes her Ashikabi, or master, for the battle royale. The Sekirei Plan begins.

Based on the manga by Sakurako Gokurakuin, it was turned into a TwelveEpisodeAnime in summer 2008 by Seven Arcs. A second season has been confirmed.
----
Tropes in ''Sekirei'' include:

* AccidentalPervert -- Minato, though usually the result of the action of one or more of his haremettes.
** AccidentalMarriage -- You may say this when Minato winged Tsukiumi and Kazehana as both of them said they are his wives.
*** Musubi and Kuu also claim to be his wife (though neither of them seem to know what this actually ''means'')
* AloofAlly -- [[spoiler: Uzume]]
* AntiMagic -- [[spoiler: Seo can surpress a Sekirei's ability as long as he's touching them]]
* ApronMatron -- Miya Asama, [[TheKanrinin the landlady]] of Izumo, is also crazy tough in combat, and thus regularly trains with Musubi.
* BadassBookworm -- Again, Matsu. She is one of the single-digit Sekirei, after all. If she has to fight, she will turn into a biker babe with a bazooka.
* LittleMissBadass -- Kusano, at least at anime episode 11 where she carried a big grenade launcher atop Matsu's motorcycle.
* BandageBabe -- Haihane, and [[spoiler:Uzume in her fighting outfit]]
* BewareTheNiceOnes -- Miya may appears to be a very nice landlady, though everyone in the house are deathly afraid of her. Of course she is [[spoiler: Sekirei Number 1, not a [[BadassNormal badass normal]] you think she is at first]]. Cue [[DemonHead Demon Head]] and [[GlowingEyesOfDoom Glowing Eyes of Doom]] every time she is angry.
* BigEater -- Every single sekirei out there, but especially Musubi.
* BikerBabe -- In a surprising bit of anime-original material, ''Matsu''.
* BlandNameProduct - Once in a while you can see {{Sony}} Vaio laptops with blanded name
* BloodKnight -- Karasuba
* BoobsOfSteel, GagBoobs, {{Gainaxing}}, MostCommonSuperpower -- ''Sekirei'': produce doesn't stand a chance.
* BookDumb - Minato is actually very intelligence, but he does badly in school since he cannot perform well when under pressure.
* BottleFairy -- Kazehana
* {{Bishounen}} -- Shiina, Yukari's Sekirei. One of the few male ones. Kagari, too. Even works at a host club.
* ClingyJealousGirl -- Tsukiumi changes from a {{Tsundere}} to this after her winging, Kusano also appears to learn to behave this way from her. Also Hikari and Hibiki (the former has a shorter fuse than the latter) does not let Seo to wing another Sekirei, and will immediately zap him if they catch him trying to do that. They don't mind if he take a male one like Shiina though.
* ClothingDamage -- Musubi is especially prone to this.
* CovertPervert -- Yukari at first appears to be a very well off, but soon, you see her getting NoseBleed around Shiina and even struggling trying NOT TO PEEK at him taking shower.
* CuteShotaroBoy -- Shiina, a {{bishonen}} one to boot, though you won't call it {{Shotacon}} because Yukari is rather short for her age (just barely [[OneHeadTaller one head taller]] than him). For once she dressed him up as a girl too.
* CompressedAdaptation -- A fine example, too. The anime uses only the most important bits, moving along at a brisk pace.
* DefeatByModesty -- Played straight in many cases, but Musubi early on is seemingly [[InnocentFanserviceGirl immune to this]]. Miya also did this to Tsukiumi in a training session.
* {{Determinator}} -- Musubi.
* DisappearedDad -- The only mention of Minatos father is 'unknown', by ''Matsu''. You just know something's up when the information Sekirei has no clue.
** Or more likely, Miya's forbidden her to reveal it.
* DoesThisRemindYouOfAnything -- The winging scenes in the anime version seem a little ''too'' sexual.
* {{Dojikko}} -- Kuno, pretty standard version.
** Haihane and Akitsu to lesser extent. The former sometimes forgets to remove her claws so that she often stab herself in the face, the latter ... forgets to wear panties!
* ElementalPowers -- Quite a few Sekirei (especially low-numbered ones) have some sort of elemental power. Specifically:
** GreenThumb -- Kusano - 108
** ShockAndAwe -- Hikari and Hibiki - 11 and 12
** PlayingWithFire -- Homura - 06
** MakingASplash -- Tsukiumi - 09
** BlowYouAway -- Kazehana - 03
** AnIcePerson -- [[spoiler:Akitsu - ?]]
** HolyHandGrenade -- apparently [[spoiler: Yume - 08]]
** DarkIsEdgy -- Shiina - 107
** Really, we're only missing an [[DishingOutDirt earth Sekirei]] at this point...
*** Mutsu may count. It's not quite clear - 05
* EmotionlessGirl -- Akitsu
* [[EverythingsWorseWithBears Everything's Worse With Bears]] -- Musubi occasionally has an animal avatar of a bear appear behind her, and the bear fist is one of her attacks.
* EyesAlwaysShut -- Karasuba
* {{Fanservice}} -- Oh yes.
* FanNickname -- The series is often simply referred to as "''{{Pokemon}}'' with tits", with each member of TheUnwantedHarem having a different ''{{Pokemon}}'' related nickname:
** Hitmonchan -- Musubi, as she fights with her fists
** Blastoise -- Tsukiumi, for her water powers
** Bulbasaur -- Kusano, for her plant powers
** Pigeotto -- Kazehana, for her wind powers
** Alakazam -- Matsu, for her role as TheSmartGuy
** Charmander -- [[spoiler:Homura]]
** And Minato is just called "L", since he resembles a slightly more well-adjusted [[DeathNote L]].
* Fanon -- Akitsu is believed to be/have been Sekirei 07.
* FetishFuel -- Hell, that crate of clothes that Yukari sent to Minato is just full of these. Also Uzume's costume collection that she gave to others in the house is, well... need to ask more? Those twins' dominatrix outfits too.
* FiveManBand -- Minato's harem:
** TheHero -- Musubi
** TheLancer -- Tsukiumi
** The CuteBruiser -- Kusano
** TheSmartGuy -- Matsu
** TheChick -- Kazehana
** TheSixthRanger -- [[spoiler:Homura]]
*FridgeLogic -- The rules state that when a Sekirei loses, they also lose the ability to be with their Ashikabi. Also, there's a battle royale going on that states that they must all fight until one is left. It doesn't really seem to make sense to give Minato a ''harem'' of these Sekirei if he's going to lose all but one of them (maybe even all of them).
** The Battle Royale only applies to teams, not individual Sekirei. Once Minato is the only Ashikabi with active Sekirei, he and his remaining Sekirei win, no matter how many are still active.
*** So it's possible for Minato to [[spoiler: wing the 108 Sekirei by himself and have all of them carry him to ascension. Sounds great but I sincerely hope it's not how this is going to finish. Also, the biggest harem in history.]]
****[[spoiler: Except most of the Sekirei have already been winged and can't be re-winged.]]
** And are you ignoring that mad scientist boss? It is possible for another way for more than one to survive, such as by blowing him away?
*** Do you really think he's not an Ashikabi himself? I bet my head he has like 7 Sekirei protecting him already.
* FacelessGoons -- those MBI soldiers
* FuroScene -- The Izumo inn's bath provides many opportunities.
** Also, there was an omake story specifically about a trip to a "neutral ground" hot spring.
* GenderBender -- [[spoiler:Homura, who finds himself growing breasts when he becomes the last unwinged Sekirei]].
* GlowingEyesOfDoom -- Miya will use these if she is REALLY pissed off. Hikari and Hibiki also use this when they are angry with Seo.
* HadakaApron -- Present and correct.
* HaremNanny -- Miya Asama, though she comes down hard on anything too ero-ero in the house.
* HoYay / LesYay -- Same sex Ashikabi/Sekirei. They've already kissed, most likely due to reacting to their future partner.
** Also used with Minato and Homura for a while, [[spoiler: after Homura started turning into a woman but before most of the cast found this out]].
* IdiotHair -- Musubi, [[FateStayNight Saber]] style.
* IllGirl -- [[spoiler: Chiho, Uzume's ashikabi]]
* InnocentCohabitation -- All of Minato's harem sleeps in his room, until they're reshuffled elsewhere for having the room get too crowded.
* InnocentFanserviceGirl -- Musubi at first, though she eventually catches onto the concept of "modesty".
* JerkWithAHeartOfGold -- Seo Kaoru, at least those two will [[ElectricTorture 'discipline']] him if he goes too far.
** Seemingly that Ashikabi of the West guy too, since he's almost a carbon copy of the above (something lampshaded in the actual manga)
* JerkAss- pretty much '''everyone else''' outside of Izumo Inn... including Minato's mother and sister.
* KillSat -- Matsu has full control of one. Probably one of the reasons why she holds so much influence in the Sekirei game.
* LargeHam -- Hiroto Minaka, chairman of the MBI and MadScientist.
* LockedOutOfTheLoop -- Miya goes out of her way to withhold information from Minato, to the point of subtly threatening people who try and reveal too much.
** Really, no one lets this guy know ''anything'' unless necessary...
* LoveFreak -- Kazehana, [[spoiler:Yume]]
* MadScientist -- Minaka Hiroto, the MBI chairman
* MakeMeWannaShout -- Kuno
* ManipulativeBastard: Higa, and how! Blackmailing Uzume, kidnapping Yukari and messing with Shiina's head (leading him to almost rape Yukari), using Uzume and Shiina to cheat at the game, cheating at the game in general, trying to join forces with Minato (which is either very stupid, what with holding his sister captive and all, or full-on MagnificentBastard territory, I'm not sure which)
* MarshmallowHell -- Chapter 49 of the manga. Rasserfrasserluckyb'tard...
* MegaCorp -- MBI, also a [[LawEnforcementInc Law Enforcement Inc]] in the city.
* {{Meganekko}} -- Resident tech geek, Sekirei and haremette Matsu.
* NoseBleed -- Minato, obviously. Surprisingly, Yukari is also prone to this, being a {{Bishonen}} fangirl.
* ObfuscatingStupidity -- Kazehana doesn't take threats seriously. She doesn't need to.
* PaintingTheFourthWall -- Kazehana talks to Minato with heart-shaped speech bubbles at one point. Miya swiftly forbids them.
* PantyFighter -- Tsukiumi in particular, as she holds the record number of {{Panty Shot}}s. Musubi ends most of her major fights in various states of undress.
* ParentalAbandonment -- apart from the missing father, Minato and Yukari's mother pretty much left them to be raised by their grandmother. [[spoiler: turns out she's working for MBI, essentially as TheDragon. She seems to care more about her Sekirei "children" than her ''actual'' ones...]]
* {{Pettanko}} -- Kusano, she is rather proud of it too. Benitsubasa on the other hand, does not seem to like being one at all, especially when [[GagBoobs Haihane]] picks on her about it.
* PowerGivesYouWings -- Or rather, wings give you power.
* ThePowerOfLove
* RetiredBadass -- Miya.
* ScaryShinyGlasses -- Matsu gets a chance to do this once or twice. Minaka also does this ALL the time that we rarely see his eyes through his glasses.
* SkinshipGrope -- Goes with the whole fanservice thing.
* SplitPersonality -- [[spoiler:Musubi. Sekirei No. 8, Yume, is inside of her. Yume is a love-crazy [[KamehameHadoken beam-user]] type, but while Musubi knows she has Yume's soul inside of her, she remembers nothing she's done ''as'' Yume.]]
* SailorEarth -- Roughly thirty or forty or so out of potentially 108 Sekirei have yet been introduced, and, most notably, the number seven Sekirei, the only one of the Single-Digit Sekirei to remain unknown, hasn't yet been introduced. Lastly, it's uncertain how many un-numbered Sekirei like Akitsu exist. In short, there's still plenty of room for Fanon to make new Sekirei.
* ShoutOut -- This troper has reason to believe that Minaka's body suit looks a lot like [[DigimonTamers Justimon's]]
* StandardFemaleGrabArea -- Minato seemingly know how to do this properly, though usually make whoever he did it to calling him a pervert.
* {{Technopath}} -- Matsu.
* TokenLoli -- Kusano.
* TwentyMinutesIntoTheFuture -- 2020, which really doesn't seem ''that'' different from today.
* {{Tsundere}} -- Tsukiumi.
* UnwantedHarem -- Subverted later on. He actually goes after his last 3 Sekirei
* ViewerGenderConfusion -- Haihane could be mistaken for male until [[GagBoobs losing her jacket]]
* XMeetsY -- ''{{Pokemon}}'' meets GagBoobs.
* YouAllLookFamiliar -- How many short-grey haired people with gray eyes are there?
** This troper cannot remember ''where'' exactly, but it's definitely Lampshaded somewhere in the series.
** Actually, Tsukiumi commented that Homura and Kagari looks very similar, though back then she was not aware that Homura and Kagari is the same person.
** I only see the grey hair, the eye colours are different. There is Homura, Mutsu, Karasuba, Shiina, and Haihane, probably more
** The male characters in particular all look relatively alike (along with spiky-haired female characters)
*YoungerThanTheyLook -- It's really easy to forget that apart from No.00/01 all sekirei are 20 years old or less. Honestly, look at Kazehana, she does not look like she was a teenager just last year.
** Of course they are some sort of aliens or at least superpowered artificial humans, what can you expect
** Manga only at least, in anime in the flashback, it is shown that most of them have adult body when Minaka found them.
