History Manga / Gokusen

** BloodBrothers: The Kurodas are very dutiful to each other.

Gokusen is fairly similar to ''GreatTeacherOnizuka'' in premise -- become trustworthy to the delinquents and teach them lessons through "{{tough love}}". However, Kumiko is properly educated and her secret background plays a large part in the series -- for example, her students think she is in debt to yakuza because of one of her poor cover-up excuses, and she brings in a rather conspicuously shady fellow when she suddenly needs to tutor her students in boxing.

** Not to mention Fuji (whom only Shin can understand, for some reason), who can tell Shin has a crush on Kumiko the second he sees them talk to each other (possibly because [[FridgeLogic he's a dog and can smell the change in pheromones]]). In the special chapters, Fuji bribes Shin with possessions or secrets of Kumiko to get him to go along with his shenanigans.

* OnlySaneMan: Shin, Shinohara, Ryuuchirou, and mostly Yankumi. Mostly.

* FiveManBand: The main students in each season easily fit into this.

* ArtShift: When Kumiko fawns over Shinohara, she sometimes looks straight out of SailorMoon.

* DawsonCasting: Avoided. High school seniors 17-18 are played by actors aged 18-22.

* UglyCute: When [[{{Gonk}} Tetsu and Minoru]] first come to the kumi:
-->'''Kumiko:''' I've always wanted cute little younger brothers!
-->'''Wakamatsu:''' I think you're the one and only person in the world who'd say that...

* AscendedExtra: Fuji. He shows up for some silliness in bonus chapters and occasionally provides some help in the manga, but in the anime, he shows up nearly every episode and even has some [[IntellectualAnimal important speaking roles]] (though no one can understand him except the audience).

* TalkingAnimal: Fuji, but only to Shin in the special chapters of the manga. To everyone besides Shin, it just sounds like barking. Even outside the special chapters, Shin seems to know what Fuji is thinking.
** In the anime he doesn't talk, but the audience can hear his very humanlike thoughts.

* CampGay: Miura becomes this when he forms some kind of weird club with two CampGay freshmen.

* SadistTeacher: This series is full of them: Shin's middle school teacher purposefully ostracized one student for no reason, Minoru's high school teacher forced him to go home because he was "polluting" the school atmosphere.... and let's not even get started on Miura, who seems to have a literal {{BDSM}} fetish besides being an {{ephebophile}}.

* BrickJoke: Near the beginning of the manga, Ucchi has to remind Kumiko to start class since she was so distracted, and he promptly gets beat up for reminding her. In the last chapter of the manga, the same thing happens, only with Kumiko's new students instead.
** Also, Kumiko being distracted enough for her students to draw on her face.

* BadassGrandpa: Of course Ryuuichirou, head of the Ooedo clan and Kuroda family, and grandfather/surrogate father to Kumiko.

* NonActionGuy: Shinohara is the only man in this series who can't hold his own in a fight. He got in trouble with some gangsters he was still in college and had to be rescued by Ryuuichirou, Kumiko's grandpa.

* EvenBadMenLoveTheirMamas: It's pretty obvious that Kuma really loves his mother, though he's not really that bad. There was even an arc in the manga devoted to Kuma considering dropping out of high school to take care of his mom, with his whole class pitching in to help so he wouldn't have to.

* ShipperOnDeck: After they find out about Shin's crush on Kumiko, Shin's friends become this.

* {{Bishonen}}: Shin. Normally, this would have every female character lusting after him, but Kumiko scarcely notices and Fujiyama has her own peculiar tastes.

* DatingWhatDaddyHates: Gender-inverted. Shin's police chief dad isn't too happy about his son liking a [[MafiaPrincess Yakuza Princess]].

* EvenBadMenLoveTheirMamas: It's pretty obvious that Kuma really loves his mother. There was even an arc in the manga devoted to Kuma considering dropping out of high school to take care of his mom, with his whole class pitching in to help so he wouldn't have to.

* JerkWithAHeartOfGold: Shin is very aloof and cold, but he goes to great lengths to help and protect his friends. He even saves Kumiko a few times, though that's arguably after the probable time he started developing a crush on her.

* LikesOlderWomen: Shin, if his crush on Kumiko is anything to go by.

* NonActionGuy: Shinohara is the only man in this series who can't throw a punch. He got in a fight when he was still in college and had to be rescued by Ryuuichirou, Kumiko's grandpa.

* TheStoic: Shin very rarely changes his expression of casual disinterest for anything or anyone.
** So when he shows anger when he hears [[spoiler: Kimiko has been tricked to get ambushed by her students]], you can see why OOCIsSeriousBusiness.

* SurroundedByIdiots: Shin. He was able to convince his friends that his bruises and cuts were from a cupboard falling on him after a huge earthquake... until Minami points out that there hadn't been an earthquake recently.

* DistaffCounterpart: As stated above, Kumiko is the Distaff Counterpart to [[GreatTeacherOnizuka Eikichi Onizuka]]. Only difference,Onizuka was a [[JapaneseDelinquents delinquent]] while Kumiko is the {{Ojou}} to a tough as nails {{Yakuza}} clan.

* LoveCanMakeYouGonk: Kumiko does this whenever she is fawning over Shinohara. Her eyes go from their usual fixed glare to big, sparkly, bishojo-standard and can flick back and forth between panels when the situation calls for it.

* {{Meganekko}}: Kumiko tries very hard to [[ObfuscatingStupidity fit this trope]], but the harder she tries, the less convincing it is.

* NerdGlasses: Kumiko's glasses are actually arguably multipurpose, and are sometimes used as MaskPower or ScaryShinyGlasses.

* ObliviousToLove: Kumiko puts so much of herself into her work and helping her students that she doesn't notice Shin's feelings towards her at all. It takes her a moment to process his confession to her and is floored when it turns out EveryoneCanSeeIt.

* TheOjou: Kumiko's yakuza family often calls her Ojou.

* SheCleansUpNicely: Kumiko. She wears a sweatsuit and NerdGlasses with her hair in pig tails at school, but she's beautiful when wearing a kimono, a little black dress, or even a girlish nightgown.

* ActionGirl: Kumiko was trained to fight by her uncles and is ''very'' effective at it.

* Bowdlerise: The arc in the manga about people from the Nekomata kumi selling drugs to high schoolers was completely changed for the anime; instead of drugs, students were compelled to buy badges shaped like ManekiNeko that guaranteed them protection from a radical group that went around beating up Shirokin students. Other than that, the story proceeded in pretty much the same way. Strangely, this was the only thing changed for the anime; guns, alcohol, and blood were still shown.
