Satoshi Yabe has become an elementary school teacher, assigned to class 6-3. The school nurse is cute and the job shouldn't be too much of a problem. Except that he got the class with the most troublesome sisters in the whole school - the Marui triplets. All of them are perverted, rambunctious and prone to causing trouble, and it's his job to teach them. Though the rest of the class is only slightly less insane...

Based on the manga of the same name, ''Mitsudomoe'' [[note]] ''Three-Way Struggle''[[/note]] was adapted into a [[TwelveEpisodeAnime 13-episode anime]] which was simulcast on Crunchyroll. The 14th episode is [[BonusEpisode only available on DVD]]. A second season, ''Mitsudomoe Zouryouchuu!'' [[note]] ''Three-Way Struggle - Getting Bigger!''[[/note]], aired in January 2011, although it only had [[CutShort eight episodes]] due to low ratings and DVD sales. It is, however, a fair bit more popular in America.

----
!!This manga provides examples of:

* AccidentalPervert -- Shinya
** Yabe is always mistaken for one.
* ACupAngst -- Mitsuba has a lot of hang-ups when it comes to her underwear.
* ActorAllusion -- How old is Ms. Sugisaki? [[Creator/KikukoInoue 17]].
* AlertnessBlink -- In general use, particularly when Yabe-sensei notices something [[HilarityEnsues hilarious]] happening.
* AllLoveIsUnrequited
* AlphaBitch -- Miku Sugisaki, Mitsuba's UnknownRival with RegalRinglets in GirlishPigtails and a haughty disposition.
* AmusingInjuries -- Tends to be a RunningGag with Mitsuba.
** And then some with her [[VitriolicBestBuds unfriendly friendly]], Miku.
* AndYouWereThere -- ''Gachiranger'' has a few interestingly shared roles. Gachi Red and Yabecchi, Gachi Pink and Miyashita, General Yamaarashi and Principal Noda, the teacher on the schoolbus and Kuriyama-sensei, the BigBad and Soujirou, the villainess and Kaieda-sensei, and the Gachirangers' monster friend and Yuudai.
* AprilFoolsPlot -- Hitoha gets a nasty case of paranoia one April Fools', worried she's going to get pranked.
* ApronMatron -- Hitoha shows some signs of this.
* ArtEvolution -- The manga's art style is rather sketchy in the original chapters but becomes ''much'' more professional as the series progresses. The students are also rather twiggy in the first few chapters but gradually round out into the PuniPlush designs seen in the anime, which probably decided (for the best) to go with the later art.
** Interestingly, one aspect of it is actually noticed in-universe: In the manga, Mitsuba originally has [[http://www.mangafox.com/manga/mitsudomoe/v01/c001/6.html much longer bangs]] until chapter 9, when her bangs [[http://www.mangafox.com/manga/mitsudomoe/v01/c009/5.html get cut evenly]]. Mitsuba then permanently switches to this hairstyle in subsequent chapters, with her original style never being seen again (contrast with Futaba, who copies the hairstyle for the rest of the chapter, but immediately goes back to normal in later chapters). In the anime, Mitsuba always has her even-bangs haircut, even in stories where she had longer bangs in the manga.
* AwLookTheyReallyDoLoveEachOther -- Happens between the sisters. Occasionally.
* BatmanGambit -- Hitoha and Yuudai's plan to win the relay race.
* BatterUp -- Soujirou uses ''[[RuleOfThree three]]'' of them at one point.
* BeneathTheMask -- Mitsuba desperately wants to be a sadistic bitch, but ultimately it is all bluster.
** Hitoha can be cruel, scary and manipulative, but she shows love and compassion towards Nipples, her cat, her sisters (occasionally) and later Matsuoka and Yabe. But she is too shy to admit it.
* BewareTheNiceOnes
* BigEater -- Mitsuba, with [[HollywoodPudgy dire consequences]].
* BigOlEyebrows -- Yuki, Yuudai and Soujirou
** Yuki gets them from her dad.
* [[BigBrotherInstinct Big Sister Instinct]]
* BitchInSheepsClothing -- Mitsuba accuses Futaba of being this in episode 2. But given the situation, Mitsuba was probably stressed so much that it was a justified outburst.
* BlandNameProduct -- The toys for Hitoha's favorite TV show, ''Gachiranger'', are made by a company called "Bonsai" - an obvious play on the real-world toy company Bandai.
* BlankWhiteEyes -- So much.
* BlindWithoutEm -- Kuriyama-sensei.
* BlueWithShock -- Especially Shinya.
** Mitsuba's entire upper body goes blue in episode 14.
* BonusEpisode -- Episode 14 is DVD-only, as mentioned above.
* BookAndSwitch -- Hitoha does this so she can get away with reading porn magazines in class.
* BrattyHalfPint -- Ryuuta, Miku's little brother
* BreakTheCutie -- Yabe suffers from this after episode two of Zouryouchuu. After having the worst Christmas ever by getting rejected by Kuriyama, sitting alone in his apartment while wearing a Santa outfit with a mannequin with glasses wearing a female Santa outfit in front of him, having his beloved mannequin fall face first onto his Christmas cake and then catch on fire, becoming Santa for Futaba when Soujirou is running late, getting the crap beat out of him by Soujirou after a misunderstanding and finally walking home in the freezing snow in nothing but a Santa hat and his boxers, his personality changes in the next episodes, becoming easily irritated, resigned and unsurprised of the weird attitude of his classmates.
* BreakingTheFourthWall -- In the "Yabecchi's Room" segment of episode 12, when questioned on her CharlesAtlasSuperpower and her dogi, Futaba's responses are "I don't know" and "ask the author".
** It happened earlier than that. In episode 2, after Futaba gave her a bloody lump on her head during a game of RockPaperScissors, Mitsuba cried out with "How many times are you going to try to kill me in this anime?!"
* BroodingBoyGentleGirl - Satou and Futaba, mostly in the manga.
* BumblingDad -- Soujirou Marui, while well-meaning, looks ''very'' [[FaceOfAThug suspicious]] to just about everybody.
* ButtMonkey -- Yabe and Mitsuba mainly, though just about every character in the series draws the short stick every now and then...
* CameraFiend -- Miku when it comes to Mitsuba.
* CastHerd -- The classroom is divided into certain cliques. Team Sugisaki (Miku, Yuki, Miyashita and Sakiko), Shinya and Yuudai (and Shinya's fangirls), the triplets and the rest. Though they overlap frequently.
* CatGirl -- After not finding the stray cat they wanted to bring home, Mitsuba gets the bright idea of having ''Futaba'' be a substitute cat. She gets really into the role...
* CharacterizationMarchesOn -- During the panty incident at the swimming pool, in the manga, Futaba hates her dad as much as her sisters, which doesn't fit with her being the only one who really loves him shown later on. The anime actually brings this scene in line with Futaba's later characterization, making her the only one not to be punished.
* CharlesAtlasSuperpower -- The only way to explain Futaba's powers is that she's almost super-human.
* ChewToy -- Yabe and Mitsuba, because the world hates them.
* ChickMagnet -- Shinya Satou, so much that perhaps half of the school was chasing him in order to get a date by being the first to show him their [[PantyShot panties]] -- even the [[{{Shotacon}} old janitor]] wanted to date him too.
** Soujirou Marui used to be one, too, until he finally let himself go.
* ChildrenAreInnocent
* ChristmasCake -- Kaieda, class 6-1's teacher. 29 going on 30, and horribly aware of it.
** It certainly doesn't help that the kids keep pointing it out. They even go so far as to nickname her "Thirty".
* ClingyJealousGirl -- The Hopeless Squad with Shinya. Also Hitoha with the hamster Nipples.
* CloudCuckoolander -- Futaba
* ColorFailure -- Happens quite often, with hilarious results. A good example is episode 13: after Hitoha discovers that the cat she and Futaba were caring for had supposedly left them (and after their father said that they could keep it and they bought cat food and toys for it too, no less), she loses all color and repeatedly fills the cat's food dish with kibble, empties the kibble back into the bag, and repeats it.
* ComedicUnderwearExposure -- A major source of comedy throughout the series.
* CoolBigSis - As revealed in her character song Choujo Dashi, ne! Mitsuba tries to be this to Futaba and Hitoha, but her tsundereness doesn't help much.
* CreepyChild -- Hitoha, albeit unintentionally.
* CuteBruiser -- Futaba, only in elementary school, can shatter various pieces of furniture (doors, desks, chairs, podiums, ''you name it!'') with her bare hands and feet.
* DaddysGirl -- Though she's not the only daughter, Futaba is the only one of the triplets who really loves her dad, faults and all.
** Averted with the other two, most of the time.
*** Except [[TastesLikeDiabetes when they were younger]].
* DancingTheme -- The OP, also synchronized to the triplets' voices. For both seasons.
* DaydreamSurprise -- Hitoha appears to brutally call out Mitsuba when she finds Miku's bra tight, but it was little more than a fantasy.
* DiggingYourselfDeeper -- Here's one from season two: Mitsuba's caught horseriding on a slimming machine. Miku's quick to insult her [[HollywoodPudgy weight problems]], and Mitsuba [[BlatantLies claims she's actually horseriding like a kid]]. Reaction?
--> '''Miyashita:''' That's even lamer.
* DirtyKid: The Marui Triplets.
* [[DisturbedDoves Disturbed Crows]]: A running gag in almost every episode.
* DoesNotLikeShoes -- Futaba
* DoesThisRemindYouOfAnything
-->'''Miyashita''' (To Yabe): "I must study your lower body parts."
* DoItYourselfThemeTune -- Both the main openings are performed by the Marui sisters' voice actresses.
* {{Dojikko}} -- Kuriyama-sensei.
* DraggedIntoDrag -- Poor Shinya...
* DumbIsGood -- Futaba's probably the nicest of the Marui siblings overall, and is ''definitely'' the dimmest of the three.
* EmotionlessGirl - Hitoha
* EverybodyKnewAlready -- When Miku is trying to find Mitsuba's weakness, she goes straight for the GoofyPrintUnderwear. Which doesn't work, since the entire class knows about it already, to the surprise of Miku and Mitsuba.
* EveryoneCallsHimBarkeep -- Most of Hitoha and Mitsuba's classmates call them The Youngest and The Oldest respectively.
* ExcitedShowTitle -- ''Mitsudomoe Zouryouchuu!''
* ExpressiveHair -- Futaba, on occasion.
* EyesAlwaysShut -- Yuudai and his mom.
* FacelessMasses -- In hypothetical scenarios, people are represented by ConspicuousCG pink girls and blue boys, who sit almost in the UncannyValley.
* FaceOfAThug -- Soujirou, again. He's a good dad, but his looks make people think otherwise. [[IWasQuiteALooker But wait till you see how he was 20 years ago.]]
* FatGirl -- Mitsuba. Even though her fatness invisible to the audience, half the characters keep making allusions to her extra pounds (especially in Season 2)
* FearlessFool -- Futaba, by far.
** [[SuperStrength Not that she really needs to fear anything, mind you.]]
** This is subverted in her character song Ottona ni Natara, in which she confesses that her only fear is to grow up.
* [[FestivalEpisode Festival Sketch]] -- In episode 2-4.
* ForeheadOfDoom -- That one female student whose forehead shines.
* FreeRangeChildren -- The Marui siblings seem to be this. They appear to go to the mall unsupervised in episode 5.
* {{Friend to All Children}} - Yabe states in his character song Sensei wa Kodomo? Kodomo wa Sensei? that he doesn't care about his students disrespecting him because he still gets along with them all.
* [[FromTheMouthsOfBabes From The Mouths Of Sixth Graders]]
* FunnyBackgroundEvent -- In the first OP, Yuudai gets {{nosebleed}}s when Hitoha accidentally shows him her book during the dance routine.
** Sometimes in the anime, (frozen) fights and arguments can be seen in the background.
* GeniusDitz -- Futaba. Where boobs are involved.
* GenkiGirl -- Futaba.
* GirlishPigtails
* GoingCommando -- Hitoha, according to Shinya.
** When convinced that Shinya likes panties more than anything (Thank you, Futaba...) Oga from the Hopeless Trio removes hers on the spot, kicks them into the stratosphere, and swears to never wear them again.
* GoofyPrintUnderwear -- A running gag is that Mitsuba tends to wear animal-print panties, despite being the oldest of the triplets. She has a collection of Zodiac animals, too!
* GratuitousEnglish -- Episode 3:
-->'''Hitoha''': [[BigOMG OH MY GAHD.]]
** At the end of Season 2's OP, the girls spell out the title as M-I-T-S-U-D-O-M-O-E instead of mi-tsu-do-mo-e.
** It's all over Season 2's ED.
* GreenEyedMonster -- Yuudai hates the fact that Shinya is so popular with the women. Even more that [[CelibateHero he wants nothing to do with them]].
* GroinAttack -- Actually the focus of an ''entire story''. The triplets try this, under the logic that if Yabe got hurt, Kuriyama-sensei would have to look at his crotch, immediately fall in love, and then he'd get laid.
* HairDecorations
** Miyashita apparently can only be recognised when wearing hers.
* HartmanHips -- For some reason, the girls in the anime are a unique combination of PuniPlush with pear-shaped bodies.
* HostileShowTakeover -- In the first season's opening. Mitsuba briefly considers changing the name of the show to ''Mitsuba-sama'', but is pushed away by Hitoha before it goes further.
* HugeSchoolgirl -- Miyashita
* {{Hypocrite}} -- Some of the kids, especially Mitsuba and Hitoha. For example, Hitoha states that she doesn't care about her height during a physical examination. [[DescriptionCut Cue a high hair bun a camera zoom-out later.]]
** HypocriticalHumor -- The result of things like that. Another staple.
* IdeaBulb -- Futaba gets a pair of these in episode 8 of the first season.
** Hitoha's is [[LampshadeHanging brilliant enough to make her sisters recoil]].
* IdiotCrows -- Usually at the end of a segment.
* [[IdiotHair Idiot Ponytail]] -- Futaba, fittingly.
* IdiotsCannotCatchColds -- Subverted, since Futaba caught one.
* ImageSong -- In order: The triplets, Sakiko, Miku, the Hopelessly in Love with Satou-kun Trio and... Nipples. The hamster has a character song. It's 4 minutes of Momoko Saito making squeaking sounds. Yabe has one as a B-side on the second season's opening, and the show's best album adds songs for Miyashita and a duet for Yuudai and Shinya. Yuki is the only major character ''without'' a song.
* InnocentInnuendo -- Another staple of the show.
** Also, Futaba to Shinya in the manga.
* IWasQuiteALooker -- Soujirou was pretty good looking back in the day, to the point that a photo of him is mistaken for class heartthrob Shinya.
* JerkWithAHeartOfGold -- Mitsuba has a dismissive attitude towards everybody, but she also slips up and reveals her kindness often.
** When Futaba made replacement pencil cases for her sisters, Mitsuba kept hers long after her sisters had stopped.
** Mitsuba doesn't hesitate to come to the defense of her sisters when they appear to be in actual danger.
* KillItWithFire -- Sakiko's method in dealing with photos that have ghosts (or Hitoha) in them.
* KindheartedCatLover -- Hitoha
* {{Kuudere}} -- Hitoha
* LethalChef -- Subverted by Futaba. It is likely that, due to her ridiculous strength, she tends to make food that comes out looking like it was crushed thoroughly (or in the case of the Valentine's chocolate she made, looked misleadingly like dog poo). Anyone who takes a first glance at her cooking may think "Is that even food?"; however, it actually tastes delicious, according to those who have tried it.
* LimitedWardrobe -- While most characters avert this, Futaba is always seen wearing either a dogi or, after she cuts that up to make pencil cases, the blue top seen in the page image.
* LockedInARoom -- Mitsuba and Hitoha get trapped in the gym storage shed when a game of cops and robbers goes astray.
** And then later on in ''Zouryouchuu'' episode six, they wind up being in their home's bathroom after Mitsuba crash lands on their side's doorknob while their dad's out cold from drinking too much.
* {{Lolicon}} -- Implied: Miku's mom.
** As of ''Zouryouchuu'' episode two, a {{Shotacon}}, too.
*** Not so much either. She just seems to obsess over [[FreakyIsCool quirkiness]]. In children. To a point where she'll try to hide in classrooms...
* LovableSexManiac -- "69" cap wearer and [[{{Nosebleed}} serial blood donor]] Yuudai.
* LoveFreak -- Yuki, complete with ShippingGoggles.
** Well, considering the fact that her parents are HappilyMarried SickeninglySweethearts...
* ManipulativeBitch
** Hitoha could, for instance...
*** Use her NightmareFace and threaten Yabe with implied student mistreatment in Mitsudomoe's variant of musical chairs.
*** Utterly beat Futaba flat in a squabble for Nipples with pornography magazines.
*** Trick Yabe into saying certain words that she can use against him to have what she wants, like forcing him to take care of Nipples.
** Oh, and while you're at it: [[JerkWithAHeartOfGold Mitsuba]] and [[AlphaBitch Miku]].
* MinorInjuryOverreaction -- Aiko tends to mummify people with simple injuries such as a nosebleed.
* MissingMom -- Nothing is ever said of where the triplets' mother is.
* MistakenForIndex -- Misunderstanding-based comedy is a staple of the series. It's rare to see an episode/chapter where someone doesn't get the wrong idea at some point.
** MistakenForCheating -- Nipples learning to backflip thanks to Futaba, coupled with some vague language, makes Yabe think there's a sexy love triangle going on.
** MistakenForGay -- Shinya and Yuudai on more than one occasion.
*** Miku's obsession with knocking Mitsuba down a peg often results in looking like a ''[[StalkerWithACrush different kind of obsession]]'' from a third (or even Mitsuba's) perspective.
*** And later Miku eating the cookie crumbs off Sakiko.
* MomentKiller -- Played straight:
-->'''Soujirou''': "Look at you three still, fighting over your old dad. C'mere so I can give you all a big hug."
-->'''Hitoha''': "I don't particularly care about you."
-->
* MundaneMadeAwesome:
** The opening scene of musical chairs is a battle on par with most war movies, set to Verdi's ''[[CrowningMusicOfAwesome Dies Irae]]''.
** Kuriyama's bandage wrapping people [[BlindWithoutEm without her glasses]] just by seeing the color red on them.
** The human curling game.
* NamesToKnowInAnime:
** HiroShimono as Yabe-cchi and Gachiranger Red
** Creator/AyahiTakagaki as Mitsuba
** HarukaTomatsu as Hitoha
** Creator/MinoriChihara as Airi
** YukoSanpei as Shinya
** Creator/ChiwaSaito as Miku
** Creator/AkiToyosaki as Yuki
** [[VideoGame/FinalFantasyX Masuo Amada]] as Soujiro Marui
** Creator/KikukoInoue as Marina Sugizaki
** Creator/TetsuyaKakihara as Gachiranger Blue
* NatureAbhorsAVirgin -- Poor Yabe.
* NightmareFace -- Take Hitoha's book away from her, and you get one of these. Or try to stop her from doing something she wants to do (such as play with Nipples).
** Or Futaba when she catches a cold.
** You know what? ''Everyone'' gets a chance at it.
* NightmareFetishist -- Sakiko
* NoDialogueEpisode -- The next-to-last segment of episode nine has no dialogue aside from some {{Angrish}} by Mitsuba.
* NoGuyWantsToBeChased -- Shinya has three fangirls after him, and he doesn't want that. [[StalkerWithACrush Given their behavior, though,]] [[{{Yandere}} you can see why...]]
** Soujirou Marui claims that he used to have the same problem back in his [[ChickMagnet hunk]] days.
* NoHoldsBarredBeatdown -- Soujirou gives Yabe one of these after mistaking him for being a pedo.
** And again in Season 2 when he ends up in the Marui residence [[ItMakesSenseInContext wearing only his boxers]].
* NoNameGiven -- Miyashita is the only major student in the class who's never given anything beyond a last name. A handful of background characters get the same treatment (like Amikawa, that girl with the really shiny forehead).
* NonstandardCharacterDesign -- Soujirou Marui is drawn in a much rougher art style with thicker lines compared to everyone else on the show.
** Also Yuki's dad is drawn in the same fashion.
** Also there's that kid whose face looks like a dog and his mother.
* NotAllowedToGrowUp -- There are several stories that feature the same yearly holiday (usually Valentine's Day and Christmas), yet the kids are always in sixth grade.
* ObviousStuntDouble: In the anime, one episode is almost entirely A ShowWithinAShow PowerRangers parody, complete with its own stunt driver (though surprisingly only during scenes with no actual stunts).
* TheOjou -- Miku's family is rich.
* OminousLatinChanting -- Hitoha walking up the steps to see Nipples is a call for the angelic choir and slow motion. She can be pretty scary when she's mad.
* OnceAnEpisode -- Poor Dad, so many times [[AccidentalPervert mistakenly questioned]] by the police.
* [[OneDialogueTwoConversations One Dialogue, Two Conversations]] -- One of the show's staples.
** In episode 3 of ''Zouryouchuu!'', it got to the point where there were '''[[UpToEleven three conversations at once]]'''.
* OnlySaneMan -- Miyashita believes herself to be the only normal one in the class, but her attempts at doing so make everyone think she's the weird one. Shinya is probably the closest to the role.
** Though as of Zouryouchuu she can be officially be considered as this. Unless she's trying to befriend Hitoha.
* {{Onmyoji}} -- Sakiko Matusoka, junior occult fan and Hitoha fangirl. She's convinced that Hitoha is one herself, and wants to join her in spirit-busting.
* OverprotectiveDad -- Soujirou loses his cool if there's even the slightest hint that a boy is getting close to one of the triplets (though he makes an exception for Shinya).
* PantyShot -- Futaba does it willingly to Shinya, with no shame whatsoever. This gets the idea in the school that letting Shinya see one's panties means he'll date them. Though it's hardly the only time panties are used for humor.
** If you pay attention, you'll notice that, for all the panty jokes and seeing panties being tossed around, we ''never'' see a traditional [[MagicSkirt up-the-skirt style panty shot]].
*** [[BrainBleach Not from a girl, anyway...]]
* PantyThief -- Yuudai willingly, Shinya by accident. Futaba to ''her own sisters''.
** Futaba literally stole them off of Miku once.
* PapaWolf -- For as much as Soujirou is a bumbling dad, if he thinks anyone is messing with his daughters, he gets serious and scary. Suddenly it's clear from who Hitoha inherited her NightmareFace, Futaba her [[CharlesAtlasSuperpower Super Strength]], and Mitsuba [[BigBrotherInstinct her protectiveness]].
* PaperThinDisguise -- Miyashita let her hair down and no one recognized her, but when she put hair pins in...
** Immediately subverted when she tries to invoke it, as all of them recognize her, [[FridgeLogic despite asking who she was just a moment ago,]] because that time she had her hair-clip in. She is understandably confused by this.
* PeekABangs -- Hitoha's NightmareFace sometimes has this hairstyle.
* PetTheDog -- Hitoha is manipulative, scary and cruel to almost everybody. But she does care for Nipples (and later, the cat), so there's ''some'' compassion in her.
** Despite she is cruel and manipulative to Yabe, deep down, Hitoha cares for him.
*** Unfortunately, everytime she shows compassion to him, he thinks the wrong idea from her.
** She is also surprisingly mild toward Sakiko, who she seems to have taken a bit of a liking to.
*** She actually hates her ([[spoiler:Especially when Sakiko spoils her Gachiranger moment in ep 7 and burns her Gachi Red photograph in Zouryouchuu ep 2.]]) but does not show it out of courtesy.
**** This is subverted [[spoiler: in Chapter 221 of the manga in which it seems that she has come to care about her, such as when Hitoha called her "Sacchan" when Matsuoka was blank and later becomes embarrassed for doing it so.]]
* {{Phobia}} -- Hitoha has a great fear of heights. You get to see it in [[VertigoEffect a very fitting perspective]], too.
* PornStash -- Yabe has one out in the open, but then it is his apartment. He just wasn't expecting Hitoha to make a duplicate key and break in...and that's not even saying anything about Hitoha's massive stash. Yabe's stash turns out to be Futaba's undoing in the cockroach-smashing episode.
* PottyEmergency -- Episode 2-6, when the girls eat bad oranges and Mitsuba refuses to let them in.
* PrecisionFStrike -- Hitoha towards Mitsuba, sometimes calling her a **** pig.
* PsychoStrings -- Whenever Mr. PapaWolf, Soujirou Marui, is about to go medieval.
* PuniPlush -- Which is much more evident in the anime adaptation.
* RunningGag -- Tons of them.
** Three girls are shown to have an obvious crush on Shinya.
** The class hamster's name (Nipples)
** Futaba's breast obsession.
** Yabecchi constantly getting the wrong idea from Soujiro.
** Soujiro always getting arrested.
** Hitoha's ''Gachiranger'' fangirliness.
** Mitsuba wanting to be called "Mitsuba-sama" as a reward for anything.
** Hitoha [[StealthHiBye always manages to hide underneath Yabe's desks and tables.]]
*** And in episode 3 of ''Zouryouchuu'' it backfired.
*** As of episode 7 of ''Zouryouchuu'' Yabe is finally used to it, moving his legs so she can get into her spot.
* SameSexTriplets
** TheHecateSisters -- Futaba is the maiden, Mitsuba the mother, Hitoha the crone.
* SayingSoundEffectsOutLoud -- Futaba sometimes goes 'tate-chitte tate-chitte' when she's in a brisk walk.
** Mitsuba usually repeats ''mushakora'' over and over when she's eating something.
* SchoolNurse -- Aiko Kuriyama
* SeasonalRot: InUniverse, the one episode of ''Honki Sentai Gachiranger'' that we actually see is apparently suffering from this, if Hitoha's reactions are anything to go by.
* SelectiveObliviousness -- Yabe is surprisingly clueless when Kuriyama calls the whole class perverted.
* ShesGotLegs -- Mitsuba.
* {{Shotacon}} -- See {{Lolicon}} example.
* ShoutOut -- The ending of episode 9 is a clear shout-out to the space station docking scene in ''TwoThousandOneASpaceOdyssey''.
** The scene in episode 13 where Soujiro breaks a hole through the girls' bedroom door and peeps through it might be a reference to ''Film/TheShining''.
* ShowWithinAShow -- ''[[{{Sentai}} Honki Sentai Gachiranger]]''.
** And the short "Yabecchi's Room" sequences.
* ShrinkingViolet -- Sometimes the reason for Hitoha's NightmareFace.
* SlapstickKnowsNoGender
* SomethingCompletelyDifferent -- Episode 1 of ''Zouryouchuu!'' is an episode of ''Gachiranger'', only occasionally cutting back to the Marui triplets.
** CallBack -- In the ending, Miyashita is dressed up in the uniform and TransformationTrinket belt like the others as Gachi Green. As Hitoha is quick to point out, "there is no Gachi Green".
** TheDanza[=/=]ThemeNaming -- Every member of the Gachiranger is named after their voice actor. Such as Red, named Hiro, who is voiced by HiroShimono.
** ResetButton -- The heroes get countless children killed, but they all come back after the MonsterOfTheWeek is defeated.
* SoundEffectBleep -- When Hitoha calls Mitsuba a "**** pig," the asteriked word is represented as pig noises.
* SpecialEditionTitle -- Episode four of ''Zouryouchuu!'' ends with a version of "Nearer My God to Thee" sung by the Marui triplets, played over stained glass windows depicting the events of the last sketch. Hitoha breaks the screen at the end, [[NightmareFace furious]].
-->'''Hitoha''': Don't make endings where I die.
** In episode 1-7 (and ''only'' episode 1-7 for some reason), the opening has sound effects added for events such as Futaba breaking things, people popping up from the sides of the screen, and Yuudai getting a NoseBleed.
** Episode 1-9 with Futaba ice-sliding to Blue Danube.
* StalkerWithACrush -- Shinya's fangirls
** Taken UpToEleven since they know his scent, handwriting, and [[{{Squick}} urine]].
* StandardSnippet -- Rather than "Yume-iro no Koi", episode nine ends with Futaba whirling across the frozen pool to the Blue Danube Waltz.
** And episode 7 of Zouryouchuu ends with replays of the curling game to the farandole from Bizet's ''L'Arlesienne''.
* StealthHiBye -- Hitoha's entrances into a scene.
* StoneWall -- Mitsuba in the curling game.
* SuperWindowJump -- Futaba leaps out a fourth story window to retrieve her dad's picture, much to the surprise of Shinya's fangirls.
* TalkingWithSigns -- Futaba, temporarily after losing her voice in episode 7 of ''Zouryouchuu!''
* TeacherStudentRomance -- Hitoha wanting to apologize to Yabe about insulting his love of ''Gachiranger'' leads to Yuki assuming that Hitoha's a StalkerWithACrush. Yet it's Yuki herself who makes Yabe actually think that when he walks in at the wrong moment.
** Hitoha and Yabe's being (or accidentally getting) unusually close is also reiterated throughout the show, even though there is no apparent sign of romantic attraction. The main example is Hitoha spending her entire time in the school under Yabe's desk, both in the classroom and in the teachers' room. Other examples include [[spoiler: Hitoha helping Matsuoka undress Yabe, Hitoha seemingly allowing Yabe to feel her "breast tumor", Hitoha having Yabe's home phone number and calling him over, and the continuation of the misunderstanding about Gachiranger (climaxing with Hitoha clenching Yabe's hand to tell him she loves them)]].
** This only happens in the anime, since their relationship is slightly distant in the manga.
* [[ThemeTwinNaming Theme Triplet Naming]] -- The sisters' names go [number]-[kanji for leaf], starting from three and working down to one.
* [[TwelveEpisodeAnime Thirteen Episode Anime]] -- The first season. ''Zouryouchuu!'' takes it even further, consisting of only eight episodes.
* ThrowTheDogABone -- Episode 13 is the first time Mitsuba does something selfless that doesn't come back to bite her in the butt.
* TomeOfEldritchLore -- Hitoha's book is treated as such. [[PowerGlows The inside of the book even glows pink]] with "forbidden knowledge".
* {{Tsundere}} -- Mitsuba and Miku
* TwinkleInTheSky -- The [[SpecialEditionTitle Episode 9]] ending.
* UglyGuysHotDaughter -- Though Soujirou apparently let his age get to him, with his current looks, it's hard to believe the triplets are related to him at all.
* UnfortunateNames -- The class hamster, named Nipples. Which leads to a scene long InnocentInnuendo where Kuriyama-sensei gets some very wrong ideas.
* UnusualEyebrows -- Mitsuba's eyebrows are giant dots.
* VerbalTic -- Futaba usually ends her sentences with "-su".
** The Gachirangers tend to add Gachi a lot.
* VitriolicBestBuds -- Mitsuba & Miku
** Also debatably Hitoha & Sakiko
* WackyHomeroom -- Big understatement.
** Not that their parents are any different.
* WeightWoe -- Mitsuba, although [[BigEater she doesn't put much effort into dieting.]]
* {{Yandere}} -- Shinya's fangirls
** Miku's mom seems to border on this at the thought of being abused.
* YankTheDogsChain -- Mitsuba finally gets some genuine fans when she twists the definition of "nympho" to suit her own ends, but has to distance herself when she learns that might have consequences.
* YuriFan -- [[spoiler: At least two of the three sisters. Hitoha's book seems to be full of this and Futaba's a fan of breasts and yuri.]]
** Yuki also appears to be in favor of the idea of Miku liking Mitsuba. Or Miyashita liking Hitoha.
*** Justified since Yuki is a LoveFreak.
* ZettaiRyouiki -- Mitsuba's standard attire, but Miku's is more elegant.
** Also, Hitoha on occasions.
** Mitsuba's a Grade S.
