->''"When I get into high school... I hope I can get 100 fuck buddies!"''

Meet Yamada ([[NoNameGiven no first name available]]), a self-described [[TitleDrop B-cupped slut]]. [[note]] The title roughly means 'B-type, H-style', [[{{Ecchi}} H]] being the Japanese code-letter for sex.[[/note]] She's entering her first year of high school, and decides on a goal for herself: to have 100 casual sex partners. How she's actually going to do that is a mystery. On her first day, she runs into Takashi Kosuda, an average student in her class. She decides to chase after him and make him her first target. Both Kosuda and Yamada are virgins, so begins an [[HilarityEnsues awkward storm of romantic hijinks]].

Along the way, Yamada and her friends are assisted by their ''eros deities'', manifestations of their sexual desires and perverse consciences that also serve as narrator, being the only ones allowed to talk to the viewer. It's worth noting that all the ''eros deities'' depicted resemble their associated characters - with some odd additions (for example, Yamada's has a white mustache, wears a pink kimono and carries a wooden staff. Mayu's resembles a chibi MagicalGirl version of her, etc.)

Based on the {{yonkoma}} manga by Yoko Sanri, ''B Gata H Kei'' received an anime adaptation in the spring of 2010 by Hal Film Maker. {{Funimation}} has licensed the anime under the name ''B Gata H Kei: Yamada's First Time''.

----
!!This series provides examples of:

* AbhorrentAdmirer: Misato is this towards Keiichi.
* AbsurdlyLongLimousine: Kyouka Kanejou's.
* AccidentalPervert: Kosuda on a few occasions, though the difference is that Yamada ''wants'' it.
* ACupAngst: Yamada. She's a B cup, so she isn't actually flat, but since her rival and her best friend are both stacked, it hits her pretty hard. (She mostly gets over it once she hears that big breasts tend to not be as sensitive as smaller ones)
--> '''Yamada''': What's up, F-cup? ''[looks at Takeshita's rack]''\\
'''Takeshita''': ''[grabs Yamada's chin]'' I have a name. Let's use it, okay?
* AllWomenAreLustful: Even Mayu has her own eros deity (thoroughly nice, of course).
* AlliterativeName: Mayu Miyano, Kazuki Kosuda, Mami Misato, Kyouka Kanejou, and Keiichi Kanejou.
* AlwaysInClassOne: In this case, in keeping with the manga's theme, Class H.
* ArtShift: The picture at the beginning of every chapter is noticeably higher quality than the rest.
* BattleAura: Displayed quite prominently by both Kyouka and Yamada when the former decided to attempt to seduce Kosuda.
* BelligerentSexualTension: Yamada and Kosuda after the first starts having genuine feelings for the latter.
* BetaCouple: Takeshita and her boyfriend, Daisuke.
* BettyAndVeronica: Mayu and Yamada, respectively.
* BigFancyHouse: Kyouka's place looks more like a Disney Princess castle than any sort of house.
* BiggerIsBetterInBed: Yamada spends a lot of time practicing how to console Kosuda for his small size. [[spoiler:She's ''very'' surprised when she finally gets a good look at it]].
* BikerBabe: Kazuki
* BishieSparkle: Kyouka's sparkles are perpetual.
** ItRunsInTheFamily: in fact, her brother takes it to near-lethal levels.
* BitchInSheepsClothing: Kyouka
* BlandNameProduct: Kosuda's camera is branded "Nihon". Yamada drinks "Coco Cola". The "[=WcDonald's=]" logo shows up.
* BokeAndTsukkomiRoutine: Yamada says something hideously perverted, Takeshita smacks the bejeezus out of her for it.
** And to a lesser extent: Misato and Katase.
* {{Bokukko}}: Kazuki, Kosuda's older sister.
* ButtMonkey: Misato's endless spirit in the face of nothing ever going right for her is nothing short of amazing.
* BuxomIsBetter: One of Takeshita's purposes in the plot sometimes seems to deconstruct this as heavily and repeatedly as possible. Yamada (and the other girls, to some extent) is always jealous of her, but at different points, Taskeshita has pointed out (among other things) that: boys talk to her chest (indeed, ''her very first sentence in the story'' is "My name is Takeshita, '''look at my face!'''), she has back pains, her large breasts get in the way in PE class, she's constantly ogled and commented upon, people assume that she's stupid because she's busty, it's hard finding bras that fit and (most famously, due to the scene's high squick factor, played for laughs) during the summer she gets painful underboob rashes from all the sweat that gathers there.
* BreakingTheFourthWall - In episode 8, three of the supporting characters have the following discussion during a field trip:
--> '''Character 1''': Man, I love field trips!
--> '''Character 2''': People naturally talk more
--> '''Character 3''': And we get more parts in the script!
** The dub adds in a few more.
-->'''Takeshita:''' ''Hey! Leave me out of your voice overs!''
*** And when Yamada is hiking through the woods:
-->'''Yamada:''' ''Huh? FOREST PORN! =D The pages are too wet from all the rain to turn.''
-->'''Eros Deity:''' ''That-a-girl, blame the rain. Make it easier for the kids at home.''
* BrickJoke: [[VaporWear The entire second half of episode 5]].
* BrotherSisterIncest: Kyouka is admittedly in love with her brother, wants him to take her virginity, and even has a StalkerShrine devoted to him. He's oblivious. Eventually, [[spoiler:when she gets a better understanding of what sex entails, she decides she never wants her brother to do something so dirty, and gives up on him]].
* CannotSpitItOut: Kosuda worries that he won't be able to make his confession of love for Yamada during their school trip to Kyoto. [[spoiler:Yamada's frustrated FreakOut moment when he finally ''does'' work up the nerve doesn't help.]]
** [[spoiler: He finally spits it out in Episode 9: ''in front of the whole class'', during a popularity contest. Yamada is not amused.]]
** Really, if either of the two could actually ''talk'' to each other, this would be a quirky one-shot hentai rather than a hilarious ecchi.
* TheCasanova: Keiichi
* CensorBox: Scenes in the televised version of the series often have the naughty bits blocked from the viewers by various things, sometimes held by the ''eros deities'' themselves, in Yamada's case. Usually, the blocking item is a picture or sign with the Demon Brand logo [[{{Motif}} that's seen throughout the series]]. Subverted in episode 11, [[spoiler: Kosuda's "naughty bit" is blocked from the viewers by Kosuda's ''eros deity'' itself, making it BLATANTLY obvious what's being hidden, as well as giving new meaning to the phrase "little man". As if that wasn't subversion enough, in Episode 12 Kosuda's ''eros deity'' is even shown ''waking up'' during a cosplay session, making things even MORE obvious (as if they weren't already)]]
** The censors are still there in the Funimation release, suggesting that they probably never intended to show anything from the start. However, [[spoiler: Yamada's naked body is fully uncensored in episode 12.]]
* CharacterDevelopment: [[spoiler:Once Yamada and Kosuda finally goes all the way in manga, Yamada downplays her idea of having sex as much and with as many guys as possible; her first time hurt, which she expected but when felt the real deal, Yamada was surprised, and the second time wasn't much better]].
* CherubicChoir: The title dropping choir, whenever something happens between Yamada and Kosuda.
* ChristmasCake: Class 2-2's 25-year-old homeroom/PE teacher, and the 27-year-old housekeeping teacher.
* ClassTrip: Episode eight.
* ColorFailure
* CoolBigSis: Kazuki.
* CrashIntoHello
* CuteClumsyGirl: Mayu, and she's somewhat GenreSavvy about how it's a weakness.
* DarkHorseVictory: ''Almost''. Kyouka proves to be sizeable competition to Yamada in the school idol contest, with Yamada winning by a slim margin.
** Played straight in episode 7, where Kyouka effortlessly wins against Yamada in a 50m freestyle swimming race. Yamada is frustrated because she's widely known as the fastest swimmer of her class.
** Averted again in Episode 9, during the athletic competition (though we don't actually SEE the loss, one of the supporting characters talks to Kyouka about it). If anything, this gets Kyouka even angrier at Yamada over it.
* ADateWithRosiePalms: Yamada frequently in the manga, and occasionally Kosuda, too: a RunningGag has the [[{{Yonkoma}} fourth panel]] featuring both retreating to this. Kosuda mentions (to himself) he's "used" Mayu for this on occasion, as well.
** Downplayed in the anime, though not completely excised as seen in the [[VaporWear nopan]] episode when Takeshita catches Yamada in the act during class [[CrowningMomentOfFunny and nearly has a heart attack]].
*** Or so she thought. Yamada just really needed to go to the bathroom and was trying to hold it in.
* DaydreamSurprise: A [[DreamWithinADream nested]] version. Yamada and Miharu engage in some SkinshipGrope action... in the minds of the boys. Who then proceed to compare wang sizes... which is also an ImagineSpot, both by Yamada.
* DeadpanSnarker: Takeshita
* DidIJustSayThatOutLoud: Yamada has a habit of loudly replying to her own inner {{Imagine Spot}}s, sometimes even with a BigNo.
* DoesThisRemindYouOfAnything: Seriously. Watch the OP and try to count the number of times suggestive imagery is used.
** A professional camera's lens extending is used as a euphemism for Kosuda getting a boner.
** Venus flytraps are shown at some point. Well... [[http://jisho.org/words/?jap=irojikake&eng=&dict=edict "Venus Flytrapping"]] is a Japanese idiom for seduction. [[AndKnowingIsHalfTheBattle So now you know.]]
** Kosuda's camera envy with Keiichi in the sports festival episode. It's the 69th annual sports festival.
** Keeping along with the 69, the second half of the 3rd episode. The folk dance after the cultural festival. Kosuda arrives late and wants to dance with Yamada, but she's disgruntled for him not being the first to ask her, so she tells him harshly to get in line. Guess how many people are in the queue? Yep, 69.
** Yamada rolled up in a blanket with a round, red face. Think about it.
* DoubleStandardRapeFemaleOnMale: At least in one of Yamada's many [[ImagineSpot imagine spots]], in which Yamada can be seen holding Kosuda down and removing his shirt, while sporting a quite respectable "rape-face".
--> Kosuda: "Yamada, I..."
--> Yamada: "Don't be such a baby!"
* EarlyBirdCameo: Kyouka appears on the cover of Kosuda's magazine in the first episode, before being introduced in the third.
* {{Ecchi}}: Very, very ecchi.
* EvenEvilHasStandards: As manipulative and self-centered as Yamada can be, she has an agonizing time formulating her reply to Kosuda's confession: Telling him no would mean giving up all her chances to use him as her stepping stone in the quest for a hundred sex friends. But telling him yes (as Takeshita advises her to after getting tired of her agonizations) is out of the question, since it would be a lie. And Yamada wouldn't deceive anyone on something as important as that to get into their pants! [[spoiler: Of course, as Takeshita has already realized, it 'wouldn't' be a lie, but Yamada is too oblivious to realize that. In the end, she goes for the {{Tsundere}} type response: "I don't hate you!"]]
* EverythingsBetterWithDinosaurs: The title image of chapter 102 features [[http://mangable.com/b_gata_h_kei/chapter-102/ Yamada riding a raptor]]. Why? Why not?
* EvenTheGirlsWantHer: Everybody is after Kyouka Kanejou when she appears in scene.
* ExpressiveHair: Just the middle bit of Yamada's cowlick [[SomethingElseAlsoRises flicks up when she gets interested]].
* EyesAlwaysShut: [[ICallHimMisterHappy Little Kosuda]].
* FailureIsTheOnlyOption [[spoiler: Thanks to {{Moment Killer}}s, Kosuda gets a ''sprained ankle'' before he can actually do the deed with Yamada. As of the end of the 1st season, they STILL haven't done it.]]
** [[spoiler:In the manga, they eventually do consummate their relationship...in ''chapter 288'']].
* {{Fanservice}}: A myriad of {{fanservice}} tropes are deliberately invoked by Yamada to catch Kosuda's eye. For the series itself, it may be easier to list which of these tropes are ''not'' used at one point or another.
* FalseStart: Happens to Kosuda when he attempts to confess to Yamada after she gets off a train. Just as he's about to [[CannotSpitItOut spit it out]], the train doors ''close around his neck before he's whisked away.''
* FestivalEpisode: Also episode two.
* FilleFatale: Chika.
* FlorenceNightingaleEffect: Yamada attempts this on Kosuda, while he's in the hospital. And then his [[HospitalHottie actual nurse]] flirts with him.
* ForeignSoundingGibberish: This is what happened in English class, and with all the students at Keiichi's school.
--> '''Kyouka Kanejou''': [[BlahBlahBlah Blah blah blah blah blah...]]
* FreezeFrameBonus: When the fireworks start in episode 2, you briefly see young versions of Yamada and Kosuda holding hands.
* FriendsWithBenefits: Yamada at one point considers her relationship with Kosuda to be ultimately this.
* GagBoobs: Miharu Takeshita and Mayu Miyano, the F-cup girls.
* GagSub: [=CoalGuys'=] {{Fansub}} version approaches this, due to its sheer saturation with [[ClusterFBomb profanity]] ("Fuckity fuck fuck fuck"), slang ("Our class is pretty baller"), and random references to things such as Cristina Aguilera, Craigslist, the Taliban, Kentucky Fried Chicken, and ''VideoGame/StarFox.'' It's not inherently inaccurate though, and opinions are [[BrokenBase sharply divided]] as to whether these liberties ruin the show or [[{{Woolseyism}} make it funnier]].
* GenderFlip: Just another story about a sexually frustrated teenager looking for lots and lots of sex and failing comically. Except that this time, the protagonist is a girl.
** Oddly enough, the male-equivalent version of this story is quite rare in the realm of anime, outside of {{Hentai}} anyway.
* GenericCuteness: Averted, characters who are supposed to look plain are indeed drawn somehow plain.
* GenkiGirl: Yamada, Misato
* GenreSavvy: Yamada makes remarks during a ImagineSpot in episode 5 about how the show so far had been a "B-type generic love comedy".
* GhostInTheMachine: The various eros deities. Yamada's is one the audience sees the most, but over time we eventually see many others:
** Kosuda's wears a bathrobe and tends to be lazy, often giving lackluster advice.
** Miyano's looks like a fairy, and gives very innocent advice ("If you kiss the cookies before he eats them, it'll be like an indirect kiss!")
** Uniquely, Takeshita has ''two'':
*** One is dressed as a businesswoman and takes relationships very seriously, giving the sort of advice that Takeshita gives to Yamada.
*** The other one, however, is a complete maneater.
** Kyouka's is a stereotypical European noblewoman, complete with fan and PimpedOutDress.
** Akai-sensei's is a high school girl, reason being that she never got a chance to mature since Akai was always busy with work.
** Kazuki's has longer hair, wears a Chinese shirt, and is very popular with other female eros deities.
** Katase's is a lonely, mature, incredibly beautiful woman.
** Chika's eros deity is identical to her in every way.
* GirlNextDoor: Mayu.
* GirlsWithMoustaches: Yamada's Eros Deity has a white moustache (and a pink kimono).
* GivingUpTheGhost: Kosuda's soul is gently hanging out of his mouth as he reflects upon how he ended up seeing Yamada underneath her skirt when she wasn't wearing any panties earlier that day.
* TheGlomp: Not even industrial equipment is going to pry Misato away from Keiichi, [[AbhorrentAdmirer much to his disquiet]].
* GoodAngelBadAngel: Yamada's and Kosuda's (both distinct from their eros deities) appear.
* GratuitousEnglish: In the manga, odd translations of the title often appear on shirts. "B Type H System"?
* GroinAttack: Poor, poor Kosuda.
* HaremSeeker: Yamada.
* HarshWordImpact
* HeroicBSOD: Yamada's Eros Deity goes [[ColorFailure white with shock]] and is insensate for about a week when [[spoiler:Yamada and Kosuda fail to have sex despite ''being naked in a love hotel'']].
* {{Henohenomoheji}}: Yamada pictures Kosuda with this face after their brief first meeting. She's honestly not far off. Kanejou's ImagineSpot also features one when she's pondering over who Yamada's supposed boyfriend might be.
%% HeyItsThatVoice moved to the trivia tab.
* HormoneAddledTeenager: Besides Yamada's quest for sex, Miharu has actually lost her virginity. Also subverted in that those who have lost it can be just as nice and decent as their chaste counterparts. Miharu is more decent than Yamada in many, ''many'' ways.
* HorribleJudgeOfCharacter: Mayu thinks that Yamada couldn't be sweeter and that Kanejo is very nice, which is completely inaccurate.
* IdiotHair: Yamada: also ExpressiveHair and SomethingElseAlsoRises.
* IHaveThisFriend: Yamada uses this to get advice from Chika, who sees through it right away.
* IWantMyBelovedToBeHappy: Mayu, in episode 5
* ImageSong: An album has been released, containing individual songs for Yamada, Miharu, Kyouka, Mayu, Kazuki, as well as group songs for Takashi and the guys, as well as a group song for Yamada, Kyouka, and Mayu.
* ImagineSpot: There are boatloads of these in every episode, since Yamada's imagination has a tendency to run away with itself.
** By the 8th episode, we have [[DreamWithinADream Imagine Spots Within Imagine Spots]]
* ImagineSpotting: Takeshita is prety good at this.
** In response to the example listed directly above:
-->''You are such a perv! Seriously, this entire bathhouse fantasy has been '''ALL YOU!'''''
* InformedAttractiveness: Yamada is treated as far and above every other girl in the school in terms of attractiveness, but most of the main female characters are pretty much just as attractive. [[LampshadeHanging Lampshaded]] when Yamada enters the school beauty contest.
* InnocentFanserviceGirl: Kazuki, mostly within her own house, but has the typical lack of shame associated with the type.
* ItsAllAboutMe: Kyouka's mansion is decorated with numerous portraits of herself. The eyes of which are all functioning video cameras.
** Also, Yamada when it comes to how much her selfishness can hurt the people around her.
* {{Jerkass}}: Yamada.
* KnowNothingKnowItAll: Yamada constantly expounds about her sexual knowledge and her eventual plans to have 100 sex friends, but in reality she has zero experience and often panics when she's faced with an actual romantic situation.
* LackOfEmpathy: Yamada. She gets better.
* LastNameBasis: Yamada is called by everybody, except her family, by her last named. And she calls everyone, except her family, by their last names.
* LettingHerHairDown: Chika, when she's showing her mature appearance.
* LethalChef: Yamada cannot cook. When Kazuki gave her Valentine's chocolate to some fish, the fish had a violent reaction.
* LovableSexManiac: Yamada, though she has traits of the CovertPervert too, jumping to sexual conclusions with everything.
** Misato seems to be following Yamada's footsteps. I mean, she's the only other with the guts to ask about sexual encounters... in public.
* LoveMakesYouCrazy: Played for laughs with pretty much everyone.
* MeaningfulEcho: Episode 9, after Miharu shocks Yamada with the idea that she really is in love with Kosuda, the exact same scene that played at the opening in Yamada's room plays again.
** Immediately [[LampshadeHanging lampshaded]] by Yamada's Eros Deity.
* MeasuringDay: Shows up in the first episode.
* MomentKiller: In almost every episode. ''Three'' times in Episode 12 alone.
** Late in the manga, Yamada's Eros Deity makes her do some image training to get more used to the idea of actually having sex. Her ImagineSpot includes a MomentKiller.
-->'''Yamada's Eros Deity:''' I have to admit, that's disappointingly accurate.
* MoodDissonance - Episode 8, which [[spoiler: ends with Kosuda's confession apparently having been rejected by Yamada. Cue the sprightly ED, with Yamada still pursuing Kosuda. Ouch!]]
* {{Meganekko}}: Mayu. She's BlindWithoutEm.
* NiceGirl: Mayu.
* NiceGuy: Kosuda, the poor, poor boy.
* NippleAndDimed: the anime at least uses GodivaHair, CensorSteam, and BarbieDollAnatomy to avoid showing Yamada's nipples, until the very last episode. It may be a bit of FridgeBrilliance that the only time the audience gets to see her nipples is in the scenes where Kosuda does.
* NoblewomansLaugh: Unusually, the protagonist herself. Kanejou is probably [[MostAnnoyingSound a parody of the trope]]. Can come off as an EvilLaugh, though, which fits the scheming it often accompanies.
* NoNameGiven: Yamada. No first name given yet.
* NoSenseOfDirection: Miyano. Taken to extreme levels in episode 11, when she [[spoiler:accidentally wanders into ''Kanejou's super-guarded "brother room".'']]
* TheNondescript: Kosuda. Yamada saw his face only as {{Henohenomoheji}} before she finally remembered him. His appearance is basically unchanged since he was young.
* OlderThanTheyLook: Mami Misato, one of the background students in Yamada's class, looks a few years younger than the rest.
* {{Ojou}}: Kyouka, complete with NoblewomansLaugh.
* OneOfTheBoys: Apparently Kazuki. She was Mayu's "prince" when she was younger.
* OneeSama: Yamada jokes about having to call Takeshita this after a near-kiss between them.
* OnTheNext: In a rare example of non-eros deity fourth wall breaking, Yamada pulls out a large wooden sign for her impending loss of virginity. Which is not going to happen any time soon.
* OjouRinglets: Kyouka.
* PaperFanOfDoom: The homeroom teacher threatens the girls with this when they don't go to sleep during the class trip.
* PatientChildhoodLoveInterest: Mayu.
* PantyShot: Provided several times throughout the series by Yamada, including a chalkboard-drawn version seen about 35 seconds into the ''opening of each episode.''
* PetTheDog: Yamada accidently does this with Mayu when her true aim was to KickTheDog.
* PoolEpisode: Episode two. The first half of episode seven as well.
* PortmanteauCoupleName: Invoked by Miss Aika when she volunteers Kosuda and Yamada, or as she calls them: [[spoiler:Kosada]], to plan out the activities for the school's Field Day.
* QuestForSex: And Yamada's not going to be nice about it, oh no...
* ReallyGetsAround:
** [[PlayingWithATrope Played with]] in the case of Yamada, who ''wants'' to be this but [[PoorCommunicationKills her inability to send clear signals]] and her extreme insecurity with all aspects of love prevent her from getting laid.
** Chika ''seems'' to be ''this''. It is extremely heavily implied (especially in the manga) that she has sex with those boys that give her gifts, and there are quite a lot of them. But in episode 12 of the anime (and in the manga sequence that scene is based on), she explicitly states to not know anything about sex, so...
--->'''Yamada:''' Have you had sex with one hundred guys!?\\
'''Chika:''' Hm? I wasn't counting.
* RichBitch: Kanejou
* SceneryCensor: Occurs when Kanejou attempts to spy on Yamada and Kosuda [[spoiler: after Yamada unzipped his pants in Kanejou's room. Kosuda's Eros Deity was blocked from view by a well-placed bit of bed railing.]]
* SchoolFestival: With Yamada's class doing a HauntedHouse.
* SexySantaDress: Yamada briefly poses in one in episode 4.
* ShipperOnDeck: Takeshita believes that Mayu is a much better match for Kosuda than Yamada is.
* ShoutOut: The ''LightNovel/MariaSamaGaMiteru'' parody in episode 6.
** "The White Death" [[http://en.wikipedia.org/wiki/Simo_Häyhä Simo Häyhä]] can briefly be seen standing behind classmate Kobayashi firing a shot from his signature rifle as she approaches a wealthy guest at Kanejou's christmas party.
*** ''"Kobayshi's taken the lead!" "Is that the White Death at her back?"''
** Why 100 fuck buddies? It's a reference to the childrens' song "Ichinensei ni nattara" where the first line is "When I become a first grader, I wonder if I can make a hundred friends?".
** In chapter 10 Yamada uses a "Lips-reader jutsu" even with [[Manga/{{Naruto}} Hand Seals]]. Doubles as an ActorAllusion, as Yamada's seiyuu voices Tenten!
** When discussing the possibility of Mayu being Kosuda's girlfriend in episode 2, Yamada rhetorically asks if she should call [[{{Golgo13}} Golgo]] to have him murdered.
** In one of Yamada's {{Imagine Spot}}s, she shoots a soccer ball through a wave, just like [[Manga/CaptainTsubasa Kojiro Hyuga]]. In the manga, the Sex God even calls her a toothless tiger.
* SiblingYinYang: Both leading families. Yamada is impulsive while her little sister Chika is more thoughtful. For the Kosuda family, Takashi is shy, while Kazuki is very outgoing.
* SingleWomanSeeksGoodMan: Yamada is clearly not going to meet her goal.
* SoundEffectBleep: The word "condoms" is always replaced with a bird chirp.
** As of Episode 9, the word "virgin" gets this treatment too.
* StacysMom: Yamada's mother is smoking--pretty impressive, considering the largely low-key art style. In a bonus chapter detailing everyone else's Sex Gods, it's noted that she doesn't have one. She ''is'' one.
* StalkingIsLove: Yamada, though it's not until Kazuki calls her out on it that she realizes what she's been doing.
* StatOVision: Yamada evaluating love hotels in episode 4.
** Misato also believes that she has this ability, but it doesn't work.
* StatusQuoIsGod: By the end of the anime, [[spoiler: the ''only'' thing changed is part of the relationship between Yamada and Kosuda. Kosuda's finally gotten the clue about what Yamada wants, and Yamada has admitted to herself (but not to Kosuda) what her feelings are becoming. Lampshaded by the titles of the three sub-episodes of Episode 12, with a teaser for a second season.]]
* StronglyWordedLetter: RealLife example: The production company staff on the show, have apparently recieved numerous threatening letters, requesting a change in the show's content and presentation. From whom? Creator/YukariTamura {{fanboy}}s.
* TheirFirstTime: And since there is a lot of planning, the [[UnspokenPlanGuarantee results are obvious]].
* ThemeTuneCameo: Yamada plays part of the OP on the recorder in episode 7, and sings the title-dropping bumper theme in 6.
** In episode 12, the same theme tune can be heard playing in the TV, and Kosuda sings the bumper version while he's in the bath.
* [[spoiler:TheyDo]]: [[spoiler:Yamada and Kosuda in the final Volumes of the manga, although not as many times a open pervert girl like Yamada would likely do, in fact she starts to think sex is serious business]].
* [[ThoseTwoGuys Those Two Girls]]: Mami Misato and Aoi Katase
* ThroughHisStomach: Miyano's plan to woo Kosuda is to feed him awesome food until he falls in love with her. Hasn't really been working for the last decade, but that's partly because everyone thinks she's cooking for his family, not him specifically.
* TigerVersusDragon: Yamada is the (rare protagonist) tiger to Kyouka's dragon.
* TitleDrop: A CherubicChoir singing the title happens ''every time'' Yamada actually admits to her relationship with Kosuda, in any way. There are also several episodes where she says the phrase. It even appears on shirts (see GratuitousEnglish).
* {{Tomboy}}: Kazuki. It's the reason why Mayu fell in love with her in the first place.
* TokenMiniMoe: Chika takes this UpToEleven. Every guy falls in love with her because she's so damn cute.
** Averted with Mami Misato. The guys ingnore her ''because'' of her child-like appearance, despite that Chika looks even younger than her.
* {{Troll}}: Poor Yamada gets mistaken for one of these when she goes online, since all she does is ask inappropriate questions about sex.
* {{Tsundere}}: Yamada can be considered a Type B [[note]]no relation to the series title[[/note]] because of how she always wants to be with Kosuda, but when he finally talks to her she acts very tsun.
* TwelveEpisodeAnime: {{Lampshaded}} in the preview for the last episode by Yamada:
--> Kosuda, it's been a year and nine months since we first met, but it feels like it's only been three months.
* TwoShorts: The first half of each timeslot has its own episode title, and the second half has a different episode title.
* UmbrellaOfTogetherness: Deliberately invoked by Yamada (ie. she steals Kosuda's own umbrella).
* UnluckyChildhoodFriend: Mayu to Kosuda, to the point that even Yamada, her rival, pities her.
* UnsettlingGenderReveal: {{Inverted}}, since Mayu's "prince" turned out to be Kazuki.
* UnsympatheticComedyProtagonist: Yamada can be often so cruel and self-centered that she's the ''perfect'' example of this trope were it not for her occasional bouts of endearing innocence.
* VaporWear: Yamada spends the entire ''second half'' of episode 5 not wearing panties. On a windy day.
-->'''Miharu:''' What the hell is wrong with you? You're wearing a skirt!
* VitriolicBestBuds: Yamada and Takeshita. Judging by how they support each other's love lives, they're best friends. Cue mutual snarking.
* {{Yandere}}: Don't forget that Yamada keeps an [[MoreDakka airgun]] with her, [[ButtMonkey Kosuda]]. And nobody [[BerserkButton messes with]] [[BigBrotherAttraction Kyouka's brother.]]
* YouGottaHaveBlueHair: The Kanejou siblings have magenta hair.
* ZettaiRyouiki: Yamada can be seen sporting it while wearing her cheerleader outfit in the series opening.
