Eriko is disgusted with her daily life in her coed junior high, and so she sees her admittance into a prestigious all-girls high school with a mix of delight and hope, believing that'll allow her to enter a world of dignity, order, cleanliness and beauty.

Oh, how wrong she is.

''HighSchoolGirls'' (also known as ''Girls' High'', and originally titled ''{{Joshikousei}}'') is a {{manga}} about a group of normal, average high school girls and the dilemmas they face involving teachers, boys and themselves. Featuring nice drawings, abundant raunchy humor and some nice lessons about life, was adapted into a TwelveEpisodeAnime series in 2006. One of the most disturbing facts about this series is that the original manga was closely based on the author's experiences going to an all-girls school, so go figure.

!!This series shows examples of:
* AccidentalPervert: Hottie Odagiri.
* AlphaBitch: Mari Saionji, an occasional recurring character.
* AnimeHair: Ayano has green hair, two of the characters have blonde hair, two of the other characters have purple/dark purple hair.
* AttentionWhore: Kouda, which is PlayedForLaughs.
* BalloonBelly: Yuma in Ep. 8.
* BasedOnATrueStory: The author, Towa Oshima, claims to have been inspired by her own high school experiences.
* BerserkButton: The normally mild Himeji is ''pissed'' when some sleazy guy tries messing with Ogawa, to the extent that she punches her boyfriend when she learns he helped arrange the whole thing.
* BitchInSheepsClothing: Momoka, oh so much. [[spoiler: She gets better in the later episodes, mainly the final one.]]
* ButtMonkey: Ayano is usually on the receiving end of physical slapstick from Yuma and sometimes Kouda, mostly for being annoying.
** If something embarrassing happens to one of the girls, it's probably going to be Eriko.
* CircleOfFriendship
* ClassRepresentative: Eriko and Kouda are forced to be class rep and vice class rep respectively.
* CurtainsMatchTheWindow: Eriko has brown hair and eyes.
* CosplayOtakuGirl: Akari Kouda, primarily in the anime. Her costumes are usually very tacky and absurd.
* DancingTheme: The EndingTheme, with the girls dancing just for fun in front of the camera.
* DroppedGlasses: Parodied with Ayano.
* EroticEating: In Ep. 4, the "Field Day" episode.
-->"Next event, the Banana-Eating Race!"
* EveryGirlIsCuterWithHairDecs: To name a few, Yuma's bunches, Ogawa's pigtails, Kouda's headband, Ayano's braids, Himeji's bunches. Eriko is the only one who almost always wears it down.
* ExpositionHaircut: Momoka.
* {{Fangirl}}: Some of their classmates.
* FestivalEpisode
* HotForStudent: There are a few scenes with Eriko and her teacher, Odagiri, that end up being a little too awkward for the both of them.
* GeniusDitz: Eriko.
* GenkiGirl: Eriko, again.
** Ogawa sometimes qualifies.
* GuysAreSlobs: Gender-inverted.
* InformedAttractiveness: For some reason, a lot of characters comment on how pretty and cute-looking Momoka is, despite her having a pretty similar character design to everyone else.
* {{Joshikousei}}: Everyone.
* KaraokeBox: Used for a date in one episode, also the location where Ayano meets Shimotakatani.
** Parodied, or something. While Yuma [[ThemeTuneCameo sings the opening theme]], Akari raps the stations along the Tōbu Tōjō Line (in order!) and Eriko recites pi to 100 digits.
* [[LoveHotels Love Hotel]]: Ogawa is lured into one, but nothing actually happens. She ends up putting her would-be assaulter to sleep. Shimotakatani ends up exposing more of himself than he probably wanted to. Poor guy had his clothes torn off by three of the girls. [[DoubleStandardRapeFemaleOnMale It's played for laughs.]]
* ManipulativeBastard: [[spoiler: Momoka, who after meeting her sister Yuma's friends, started spreading rumours that Ayano was cheating on Shimotakatani, in order to try and break up the friendship group, all just because she's jealous of not having any female friends herself.]]
* MeasuringDay
* {{Meganekko}}: Ayano.
* NoPeriodsPeriod: Averted. For example, Auntie Flo calls on Yuma at critical moments in two episodes of the anime.
* OlderThanTheyLook: Ogawa is one of the older students, but looks younger than the freshmen.
* OneGenderSchool
* PantyShot: Every now and then.
* PoorCommunicationKills: The entire reasoning behind the girls thinking Kouda has a terminal illness when [[spoiler:she's staying in-character for an audition]].
