->''"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. Considering that she's a virgin and rather clueless about dealing with the opposite sex, 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 who is also a virgin. She decides to make him her first conquest and clumsily pursues him, thus beginning 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 narrators, being the only characters who are allowed to talk to the viewer. All of the ''eros deities'' 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. Creator/FUNimation has licensed the anime under the name ''B Gata H Kei: Yamada's First Time''.

'''Note:''' All character tropes go to the newly created character page!

!!This series provides examples of:

* 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.
* AnAesop:
** When it comes to teenagers, everybody's still figuring out their sexuality, and sometimes even the ones you'd think are popular and experienced really have no idea what they're doing either. Most members of the opposite gender feel just as awkward about their sexuality (and have just as much sexual desire) as you do, so talking about it honestly and openly might be the best way to resolve those problematic situations.
** [[spoiler: It's easy to have an [[IdealizedSex idealized view of sex]] if you've never had it before, but there are all sorts of problems that can occur for the inexperienced. Even once you get the hang of it, you'll realize it's not practical or necessary to have sex with your partner 24/7; every once in a while is fine too.]]
** Lots of young folks who haven't had sex yet think it would be great to be TheCasanova and sleep around with a lot of different people, but most of us can't do that, and it's not even all it's cracked up to be. You might realize that being in love and having a committed relationship with one person is more satisfying in the long run.
* ArtShift: The picture at the beginning of every chapter is noticeably higher quality than the rest.
* BelligerentSexualTension: Yamada and Kosuda after the first starts having genuine feelings for the latter.
* BlandNameProduct: Kosuda's camera is branded "Nihon" (it also says "Nikkon" in one spot, oddly enough). 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.
* ButtMonkey: Misato's endless spirit in the face of nothing ever going right for her is nothing short of amazing.
* 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]].
* 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.]]
* CherubicChoir: The title dropping choir, whenever something happens between Yamada and Kosuda.
* ClassTrip: Episode eight.
%% * CrashIntoHello
* 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.
** 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]]. This was one of few scenes toned down in the English dub, in which the internal narration suggests that Yamada just really needed to go to the bathroom and was trying to hold it in.
* DatePeepers: They appear in ''episode 4'' when Kosuda and Yamada make out in the park. It cuts their date short.
* 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.
* 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. He's jealous that Keiichi's camera has a much longer lens than his. 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!
* {{Ecchi}}: Very, very ecchi for its highly sexual story, although the actual fanservice is less frequent and more restrained than might be expected from the premise, with even the sexual scenes more focused on comedy and/or romance than on titillation.
* EverythingsBetterWithDinosaurs: The title image of chapter 102 features [[http://mangable.com/b_gata_h_kei/chapter-102/ Yamada riding a raptor]]. Why? Why not?
* ExpressiveHair: Just the middle bit of Yamada's cowlick [[SomethingElseAlsoRises flicks up when she gets interested]].
* EyesAlwaysShut: [[ICallHimMisterHappy Little Kosuda]].
* FailureIsTheOnlyOption: Yamada really wants to get laid but every time she gets close to no longer being a virgin ''something'' gets in the way.
** [[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.
* FestivalEpisode: Also episode two.
* 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.
* GagBoobs: Miharu Takeshita and Mayu Miyano, the F-cup girls.
* GagDub: The dialogue has been punched up to be [[DubText more suggestive and slangy]], also infrequently BreakingTheFourthWall. For every distinctly Japanese reference LostInTranslation, [[Creator/FUNimation FUNi]] usually will have [[CulturalTranslation slipped in an equivalent]] elsewhere.
--> '''Miyano, in one of Yamada's [[ImagineSpot delusions]]''': If you're ready, I brought "you-know-what"[[note]]Oni Brand condoms, explicit mention of which was censored in the English release[[/note]] with me...\\
'''Kosuda (original)''': All right...!\\
'''Kosuda (English dub)''': [[Creator/CharlieSheen Winning]][[MemeticMutation ...!]]
* 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 Christina 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.
* GhostInTheMachine / LoveGoddess: The various eros deities. See the character page for more information.
* GraduationForEveryone: In the manga. All of the characters graduate besides [[spoiler:Akimoto Kouta]].
* GratuitousEnglish: In the manga, odd translations of the title often appear on shirts. "B Type H System"?
* HarshWordImpact
* {{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.
* 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.
* 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]]
%%* {{Jerkass}}: Yamada.
%%* LackOfEmpathy: Yamada. [[spoiler:She gets better.]]
* 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. She also generally restricts her advances to Kosuda, although at least initially she plans to change that after losing her virginity.
** 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.
* LoveHotels: Yamada wants to take Kosuda to one and analyzes them rigorously.
* LoveMakesYouCrazy: Played for laughs with pretty much everyone.
* MaybeEverAfter: [[spoiler:Unlike the manga]], the anime ends with [[spoiler:Yamada still not having acknowledged her feelings for Kosuda, nor given up on her goal of sleeping with 99 other guys after him; and no resolution has been given for either of her romantic rivals. The tone of the ending certainly suggests things will work out, though.]]
* 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!]]
* NippleAndDimed: the anime at least uses GodivaHair, CensorSteam, and BarbieDollAnatomy to avoid showing Yamada's nipples [[spoiler:until the very last episode]]. It may be a bit of FridgeBrilliance that the audience doesn't gets to see her nipples [[spoiler: until Kosuda does]].
* OneeSama: Yamada jokes about having to call Takeshita this after a near-kiss between them. Later in the manga, Yamada suggests Mayu call her this as well.
* 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.
* PaperFanOfDoom: The homeroom teacher threatens the girls with this when they don't go to sleep during the class trip.
* PetTheDog: Yamada accidentally 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.
* 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 '''trying''' to have sex[[note]]Yamada asks her how to have sex without screwing up, leaving ambiguity as to whether Chica's claim to know nothing means she doesn't know anything about having sex or just hasn't ever had to worry about screwing up[[/note]], so...
--->'''Yamada:''' Have you had sex with one hundred guys!?\\
'''Chika:''' Hm? I wasn't counting.
* 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.
* SexComedy
* SexIsGood: General perspective of sexuality in the series, mostly personified through the Eros Deities.
* 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 children's 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 Manga/{{Golgo|13}} 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.
** In chapter 196, Yamada shouts "That's brilliant! Yamada, bring me ten cushions!" to Takeshita, who says "Yamada is you." This is actually funnier if you ''don't'' get the reference, but even Yamada isn't quite a big enough {{Cloudcuckoolander}} to forget which character she is. She's referencing ''Shōten'', the second-longest-running TV series in Japan, in which ''rakugo'' comedians compete for cushions and the first to ten wins. The assistant and ChewToy who brings more cushions is named Yamada-kun.
* 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.
* 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.
* TheyDo: [[spoiler:Eventually, Yamada and Kosuda form an official romantic relationship and give each other their virginities. Once no longer virgins, the couple doesn't become the sex-crazed lovers Yamada originally wished for, but her view of sex and love has changed. [[note]]The lack of active sex might also be due to how painful sexual penetration is for her the first few times they have sex[[/note]]]].
* 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).
* {{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.
-->'''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. She hides Kosuda's own umbrella, then offers to share her umbrella as the two walk to his house, where she hopes to get invited inside.
* {{Yandere}}: Don't forget that Yamada keeps an [[MoreDakka airgun]] with her, [[ButtMonkey Kosuda]]. And nobody [[BerserkButton messes with]] [[BigBrotherAttraction Kyouka's brother.]]
* ZettaiRyouiki: Yamada can be seen sporting it while wearing her cheerleader outfit in the series opening.
