"When I get into high school... I hope I can get 100 fuck buddies!"
Meet Yamada (no first name available), a self-described B-cupped slut. note The title roughly means 'B-type, H-style', H being the Japanese code-letter for sex. 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 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 Magical Girl version of her, etc.)Based on the yonkoma manga by Yoko Sanri, B Gata H Kei recieved 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.
Accidental Pervert: Kosuda on a few occasions, though the difference is that Yamada wants it.
A-Cup Angst: 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?
Brother-Sister Incest: Kyouka is admittedly in love with her brother, wants him to take her virginity, and even has a Stalker Shrine devoted to him. He's oblivious. Eventually, 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.
Cannot Spit It Out: Kosuda worries that he won't be able to make his confession of love for Yamada during their school trip to Kyoto. Yamada's frustrated Freak Out moment when he finally does work up the nerve doesn't help.
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.
Censor Box: 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 that's seen throughout the series. Subverted in episode 11, 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, Yamada's naked body is fully uncensored in episode 12.
Chaste Teens: Strongly averted. 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.
Character Development: 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.
Cherubic Choir: The title dropping choir, whenever something happens between Yamada and Kosuda.
Christmas Cake: Class 2-2's 25-year-old homeroom/PE teacher, and the 27-year-old housekeeping teacher.
Dark Horse Victory: 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.
A Date with Rosie Palms: Yamada frequently in the manga, and occasionally Kosuda, too: a Running Gag has the fourth panel featuring both retreating to this. Kosuda mentions (to himself) he's "used" Mayu for this on occasion, as well.
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.
Even Evil Has Standards: 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! 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!"
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.
False Start: Happens to Kosuda when he attempts to confess to Yamada after she gets off a train. Just as he's about to spit it out, the train doors close around his neck before he's whisked away.
Gag Sub: CoalGuys' Fansub version approaches this, due to its sheer saturation with 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 Star Fox. It's not inherently inaccurate though, and opinions are sharply divided as to whether these liberties ruin the show or make it funnier.
Gender Flip: 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.
Generic Cuteness: Averted, characters who are supposed to look plain are indeed drawn somehow plain.
Heroic BSOD: Yamada's Eros Deity goes white with shock and is insensate for about a week when 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 Imagine Spot also features one when she's pondering over who Yamada's supposed boyfriend might be.
Hot Mom: 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.
Image Song: 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.
Imagine Spot: There are boatloads of these in every episode, since Yamada's imagination has a tendency to run away with itself.
You are such a perv! Seriously, this entire bathhouse fantasy has been ALL YOU!
Informed Attractiveness: 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. Lampshaded when Yamada enters the school beauty contest.
Innocent Fanservice Girl: Kazuki, mostly within her own house, but has the typical lack of shame associated with the type.
It's All About Me: 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.
Know-Nothing Know-It-All: 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.
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...
Scenery Censor: Occurs when Kanejou attempts to spy on Yamada and Kosuda 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.
Misato also believes that she has this ability, but it doesn't work.
Status Quo Is God: By the end of the anime, 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.
Through His Stomach: 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.
Title Drop: A Cherubic Choir 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 Gratuitous English).
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 because of how she always wants to be with Kosuda, but when he finally talks to her she acts very tsun.
