Izumi and Mitsuki have run away from home and are looking for work. Where to go? They happen to stumble upon the house of 14-year old billionaire Yoshitaka Nakabayashi, who's looking for [[{{Meido}} maids]]. Yoshitaka lets the girls stay and relax, but leaves them maid outfits to change into when they get out. Shortly before they leave, Izumi breaks a very expensive pot, and so she and her sister are roped in working to pay off their debt. Throw in a perverted alligator, a third maid from Yoshitaka's school (also a [[SchoolgirlLesbians schoolgirl lesbian]]), and it all takes off from there.

Not to be confused with ''TheyAreMyNobleMasters''.

!!This anime provides examples of:

* AirVentPassageway: Used when they are trying to rescue Mitsuki in the fourth episode, but it is [[TruthInTelevision so loud]] the Mitsuki-chan Defense Squad hears them coming immediately.
* AllWomenAreDomsAllMenAreSubs - Yoshitaka never succeeds in fulfilling his sick demented fantasies despite his power over the girls (and Mitsuki's apparent eagerness). In fact, he's tied up and whipped by Izumi and some French girl he tries to seduce at one point.
* AlwaysInClassOne: Izumi and Yoshitaka are shown to be in class 2-A. Being in the same class is convenient for Yoshitaka, but isn't for Izumi for the same reason. Anna is also in that class.
* AmusingInjuries: Yoshitaka is hurt quite a lot for the sake of the comedy. [[PayEvilUntoEvil Often deservedly so.]] This is even taken UpToEleven when we can see his face restoring real time after it became unrecognizingly deformed all this while talking back to Izumi.
* AndTheAdventureContinues: The anime's ending.
---->Izumi's debt for the day:
------>The End
* ArtShift: The anime and the manga's art styles are very different. Also, Pochi in the first manga volume is drawn more like a realistic alligator, but becomes the cartoonish blimp he's most known as in the next volume. The characters actually bring this shift up in one chapter, with the explanation being that "Pochi has gotten fat."
* AuthorAvatar: Mattsu is portrayed as an alligator, and Asu as a hamster. Due to the fourth wall never having existed for the manga in the first place, they are literally part of the main cast by now.
* BigFancyHouse: Complete with a front and back yard the size of several parks put together. Mitsuki was even able to let her defence force build an full scale indoor beach without the other even noticing it!
* BitchInSheepsClothing: [[spoiler: Mitsuki]]. It becomes increasingly obvious with each manga volume. Izumi doesn't notice.
* {{Bowdlerize}}: The German release ups the girls' ages by three in the dub and the sub.
* BuxomIsBetter: Izumi gets a lot attention from other characters because of her large breasts.
* CharacterizationMarchesOn: WordOfGod points out that in early chapters, Anna is supposed to be the "innocent, naive character", but he decided to change her and make her a Yoshitaka-level pervert.
* TheChewToy: Izumi and Yoshitaka. Usually one is the cause of the other's misfortune.
* ChivalrousPervert: Pochi the alligator, particularly in the manga. The author's notes in Volume 2 even note that the big difference between him and Yoshitaka is that Pochi actually gives a damn about the girls he pursues; as people, not objects.
* ClingyJealousGirl: Anna, who refuses to share Izumi with anyone, especially men.
%% * ClothingDamage: Mostly Izumi's.
%% * CloudCuckooLander: Mitsuki. [[ObfuscatingStupidity Or not.]]
* ComedicSociopathy: This trope is the main source of the series' humor, not to mention in the most extreme ways possible.
%% * CosplayOtakuGirl: Mitsuki
* CostumeExaggeration: A guest character agrees to have a competition with the show's resident lech. The former excels at designing several costumes with noticeably less Costume Exaggeration than the latter, before the lead girl is convinced there's not enough of a functional difference to bother changing employers. (That and the new employer loves crossdressing, which is a step too far for the girl who gets [[BlackComedyRape abused]] on a daily basis by every other main character.)
%% * CostumeInertia
%% * {{Ecchi}}
* DieHardOnAnX: In the mansion itself on the fourth episode, complete with hidden guns bandaged in the back of the protagonist character, and even quoting the title "Die Hard".
* DoubleStandardAbuseFemaleOnMale: No one seems to mind all the abuse that Yoshitaka suffers, although the vast majority of the time he deserves it.
* FanService: The entire point of the series.
%% * GagSeries
%% * {{Gainaxing}}: It's made by StudioGainax, of course.
%% * GainaxEnding: See above trope.
%% * GenkiGirl: Mitsuki
* {{Greed}}: Yoshitaka seems to show signs of this, even though he already has everything one could want.
* GoGoEnslavement: See Fan service.
* HalfArcSeason: There are only 12 episodes in the anime, and episodes 7-12 have a slowly advancing plot regarding Izumi's dream to be an idol and Yoshitaka's [[TheRival rival]] Seiichirou.
* HappinessInSlavery: The ending of the anime strongly implies that the girls are perfectly happy serving Yoshitaka, despite all the complaints from Izumi before.
* HeyItsThatVoice: The ghost of Yoshitaka's father has the same voice actor as [[GGundam Master Asia]]. And the same face.
%% * InstantFanClub: Mitsuki's.
* InTheBlood: Izumi and Mitsuki's parents; the father is alot like Izumi and the mother is alot like Mitsuki.
* IndenturedServitude: In the first episode Izumi breaks a vase worth 5 million yen. She becomes a maid to the vase's owner to pay off her debt to him.
* JerkWithAHeartOfGold: Yoshitaka constantly walks the line between this a straight up JerkAss as he is revealed to have ulterior motives. In the final episode he seems reformed, but it is all eventually revealed to have been a {{plan}} to [[spoiler:renew Izumi's contract]]. However, some internal dialogue, which he would have had no reason to fake since the other characters couldn't hear him, suggested that he may have been serious about [[spoiler:wanting to marry Izumi]]. So, [[AlternateCharacterInterpretation it's up to the viewer to decide which he is.]] The manga is an aversion because [[JerkWithAHeartOfJerk Yoshitaka is irremediable]].
* KingOfAllCosmos: Mattsu is "the alligator god" whom Izumi regards as a semi-malevolent [[JerkassGods Jerkass God]].
%% * LampshadeHanging: Several times, both by the author and by Yoshitaka.
* LethalChef: Anna. Alone the smell can make both humans and alligators fainting.
* [[ManipulativeBastard Manipulative Bitch]]: Mitsuki. Her mother is even WORSE; while Mitsuki is also cute when scheming and has some [[PetTheDog genuine kind moments]], her mother...isn't and doesn't.
* MegaTonPunch: Yoshitaka suffers these a lot, often from Izumi.
%% * {{Meido}}
* MsFanservice: Izumi's status is enforced by the other main characters.
* NoEnding: The manga. Just when it looks like all is wrapped up, [[YankTheDogsChain the last panel undoes it completely.]]
* NoFourthWall: In the manga.
* OperaGloves: As seen above, Izumi, Mitsuki and Anna all wear long white gloves (with black cuffs at the top) as part of their {{Meido}} outfits.
* ParentalIncest: The girls ran away from home in the first place, because ''they got tired resisting their father's constant sexual advances''.
-->'''Father''': I love you both just as much as your mother!\\
'''Izumi''': Ewww!\\
'''Father''': Just as much!
* PricelessMingVase: Izumi debt start with her smashing a vase worth 5,000,000 yen. Since she smashing something just about every time she is cleaning up and the house is full of expensive things you can probably guess which way the debt is going...
%% * PsychoLesbian: Anna.
* TheRival: Seiichirou for Yoshitaka and Takami for Izumi (though the latter is subverted in the anime, where [[spoiler: Takami is actually just acting the part of Izumi's rival as part of Yoshitaka's {{plan}}.]]
%% * SchoolgirlLesbians: Anna again.
%% * SensualSpandex: The girls' gym uniforms.
* ShoutOut: ...to a lot of other Gainax titles.
%% * SlapstickKnowsNoGender: Poor Izumi.

* TheSociopath: Yoshitaka, definitely, though PlayedForLaughs. Quite possibly Mitsuki and Anna too.
%% * {{Stripperiffic}}: The maid "uniforms".
* TokenYuriGirl: Anna towards Izumi, to the point of StalkerWithACrush. Izumi doesn't exactly reciprocate the feelings, but the cast (including Izumi, with [[LiteralGenie promises]]) do use Anna's obsession to their advantage on occasion.
%% * TwelveEpisodeAnime
* UnwantedHarem: Izumi has a rather mixed collection: her villainious master Yoshitaka, her fellow maid and resident lesbian Anna, the perverted alligator Pochi, and crossdressing Seiichirou. And no, she don't want any of them.
* VillainousCrossdresser: Yoshitaka's cousin Seiichirou. He is nice enough in the anime, but kidnapping Izumi in the last volume of the manga and trying to manipulate her certainly don't earn him a place among the good guys.
%% * VillainProtagonist: Yoshitaka.
* WorkOffTheDebt: The whole premise of the show.
