History Manga / Gokusen

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

* Meganekko: Kumiko.

* ArtEvolution: If you saw a panel from the first volume next to a panel from the last one, you might think they were from two different artists. In the beginning, scenes were very minimal, and some pages contained only panels with text boxes in them, but they, as well as faces and poses, become progressively more detailed. Some readers are turned off by the fact that everyone is a {{Gonk}} at the beginning, but by the middle you can tell who's supposed to be attractive. Shinohara and Shin's transformations are most apparent since they're the most good-looking.

* InformedAttractiveness: Anyone who is called good-looking before the ArtEvolution that improves the look of the attractive people's faces.

* BetweenHerLegs: Used in the fourth chapter, when Kumiko angrily confronts Shin.

* {{Noodle Incident}}: Between Kuma and Shin. ''"And when we were on Mt. Hane, I took the bento . . ."''

Shinohara and Shin's transformations are most apparent since they're the most good-looking.

* {{Gonk}}: So many that you can actually tell which characters are genuinely attractive, rather than leaving it up to InformedAttractiveness.

* LoveTriangle: Shin -> Kumiko -> Shinohara. [[spoiler: Manga Canon points to Shin and Kumiko getting together]]

** FamilyUnfriendlyViolence : Serious beatdowns are given to high school students almost OnceAnEpisode, with little recourse to the BattleDiscretionShot. On the third hand...
** HollywoodHealing : Students limp home from said beatings with a little cosmetic blood and a sympathy-grabbing wince when in real life they would probably have broken bones, concussions, internal bruising, etc.

* [[SortingAlgorithmOfEvil Sorting Algorithm of Badass]] : Yankumi can face down her crop of high school badasses because, as inclined as they are to fighting and getting in trouble, she was raised by the yakuza and delinquents are just small fry compared to her folks back home. Most of the threats Yankumi faces are somewhere in between her own rank on the scale and that of her students.

* [[ThePiratesWhoDontDoAnything The Yakuza Who Don't Do Anything]] : Yankumi's yakuza family are never involved in organised crime. In fact, their only source of income appears to be from a small roadside food stall.

* [[spoiler: WillTheyOrWontThey: TheyDo: Shin and Kimiko get together in the [[LastMinuteHookup last chapter of the series.]]]]

* OddlySmallOrganization: Kumiko's Yakuza Family. A new gang member noticed this and thought this meant they were easy pickings. The leader of said group knew that despite being small each member was pretty much a OneManArmy and the leader has the influential power to pretty much summon every yakuza member to his side at a moments notice.

** So when he shows anger when he hears [[spoiler: Kimiko has been tricked to get ambushed by her students]], you can see why {{OCC Is Serious Business}}.

* TalkingAnimal: Fuji, but only to Shin in comic-interlude episodes of the manga

* TheStoic: Shin very rarely changes his expression of casual disinterest for anything or anyone.

* [[Spoiler: TheyDo: Shin and Kimiko get together in the [[LastMinuteHookup last chapter of the series.]]

* EvenTheGuysWantHim: Believe it or not, Kumiko's grandfather was [[http://www.mangareader.net/1664-52963-12/gokusen/chapter-36.html described as this in his youth]].

* ScaryShinyGlasses: Miura-sensei

* {{Pointy-Haired Boss}}: The leader of the Nekomata-kumi. His underlings wonder why they even work for him, and when Kudou's plan to kidnap Kumiko falls through and Kuroda invades the Nekomata headquarters, the leader is the only one who didn't get to escape because he had ''knocked himself out with his backscratcher.''

* FriendlyNeighborhoodYakuza: The Kurodas engage in illegal activity but nothing appears to be all that immoral or cruel. To the point the neighborhood actually really like them.

* NeighbourhoodFriendlyGangsters: The Kurodas engage in illegal activity but nothing appears to be all that immoral or cruel. To the point the neighborhood actually really like them.

* ActionGirl: Kumiko was trained to fight by her uncles and is ''very'' effective at it
* BadassTeacher: Kumiko; Fujiyama is also very protective in her own way, though she's no ActionGirl like Kumiko

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

* CatchPhrase: The head teacher frequently demands to know whether Yankumi is "doing something unnecessary". Yankumi calls her students ''daiji na seito'' my precious students.

* EpicFail: In the Live Action series, her over-enthusiam often scares away the non-delinquent classes she teaches.
* TheGlassesComeOff: Kumiko always unties her pigtails along with removing her glasses before a fight.

* OnlySaneMan: The second season's Odagiri Ryu.

* SuspiciouslySimilarSubstitute: Each season begins with Yankumi going in to teach at class 3-D of a new school, which is filled with bishounen delinquents who she inevitably wins over, helping them with their troubles over the course of the season, culminating in their graduation. Each season also features new love interest for Yankumi, with the old ones disappearing without a trace except Baba in seasons 2 and 3. Seasons 2 and 3 also have Yankumi being fired from a different teaching job for teaching her students yakuza phrases, before going to that season's class 3-D. Each class also seems to feature one student who acts as the [[OnlySaneMan Only Sane Man]] and has father issues and an implied crush on Yankumi (Shin in Season 1, Ryu in Season 2, and Yamato in Season 3).

* {{Berzerk Button}}: Kumiko and her fellow teachers don't like it when someone takes a crack at their students.
