%%IT'S SPELLED "ONANIE". With an "e" at the end, yes. It's a Dutch loanword into Japanese (see this Japanese Wikipedia article: http://tiny.cc/d6m4t). Also, notice the logo in the page image there?%%
%%You realize that no translation, not even an official one is not absolute, right? Only Word of God has the right to make that kind of call. Plus, look at this and see how there's no set standard for romanization of long vowels and how debated this is outside of this word: http://tmau.fateback.com/articles/wir/wir02.html. Both are "correct" romanizations of the word; they're just different modifications to Hepburn Romanization of long vowels. Onanie is wapuro, and onani is dropped. Seeing as: 1) the target audience (i.e. anime fandom) typically only switches over to wapuro with the elongated "o" sound with "ou" and 2) the title of the trope page uses the "dropped" style of romanization already, all references to the work should be "onani."

Describe ''Onani Master Kurosawa'' here.

It's ''Manga/DeathNote'' [[XMeetsY but with fapping]].

[[IdiotBall Hey, you asked.]]

But seriously. ''Onani Master Kurosawa'' (lit. "Masturbation Master Kurosawa") is about the eponymous Kakeru Kurosawa, a middle school student in Japan who...[[AllMenArePerverts spends his time masturbating in the seldom-used girl's bathroom on the third floor of his school]]. It's also about a girl named Aya Kitahara who is [[BreakTheCutie constantly bullied]] by the more popular girls in class until Kurosawa imposes justice onto them by--yes--masturbating onto their clothes. [[MundaneMadeAwesome With dramatic facial expressions that would make Light Yagami blush]]. Kitahara figures out that it's Kurosawa who did the deed and blackmails him to traumatize other girls for her until she ends up picking a target they both soon regret. And from that point it gets really ''Literature/TheCatcherInTheRye''-ish. And that's just about all that can be said without going into spoiler territory.

Being done as a voice drama [[http://www.onamas.net/ here]].There is also an after-story of sorts [[http://faildoor.wordpress.com/2009/08/07/after-the-juvenile-part-1/ here]] and [[http://faildoor.wordpress.com/2009/08/13/after-the-juvenile-part-2/ here]]. A mini comic depicting humorous scenes not previously shown can be found here courtesy of this deviantart user [[http://zeroproxy.deviantart.com/art/Onani-Master-Kurosawa-Mini-Comic-1-291875558/ here]].

Not to be confused with ''StrongestLegendKurosawa''.

* AllOfTheOtherReindeer
* AllJustADream: ALL of the {{Ecchi}} scenes are Kurosawa's Wild Imagination.
* AnguishedDeclarationOfLove: Subverted in a chest-stabbingly cruel scene. [[spoiler:Kitahara is forced to "confess her love" for Pizzata by her Harada and Sugawa, and then soon by ''the entire class'' cheering for it. This later gets painful for Pizzata too, as he starts having (unrequited) feelings for her.]]
* TheAtoner: [[spoiler:Kurosawa after admitting to the class what he did, and getting bullied for it.]]
* BatmanGambit: [[http://www.mangafox.com/manga/onani_master_kurosawa/v01/c005/15.html This one is exceptionally played.]]
* BewareTheNiceOnes: [[TheDogBitesBack REVENGE!]] Kitahara just [[http://www.mangafox.com/manga/onani_master_kurosawa/v01/c007/19.html this]].....and [[http://www.mangafox.com/manga/onani_master_kurosawa/v03/c022/8.html this]] sorta make a terrifying image for Kurosawa (And some readers)
* BirdsOfAFeather: [[spoiler:Takigawa and Nagaoka.]] As much as [[spoiler:Kurosawa]] hates it at first, he eventually admits that these two are made for each other.
** OppositesAttract: [[spoiler:Kurosawa himself and Sugawa]] in the last chapter.
* BoundAndGagged: [[http://www.mangafox.com/manga/onani_master_kurosawa/v01/c005/ Happens to]] [[AlphaBitch Sugawa]] in one of Kurosawa's... fantasies.
* BreakTheBadass: [[spoiler:Kurosawa, upon seeing Takigawa and Nagaoka together.]]
* BreakTheCutie: Kitahara again, in a terrifyingly realistic way.
* CantActPervertedTowardALoveInterest:
** Kurosawa gets sick when he first tries fapping to [[spoiler:Takigawa]].
** Later gets a bit squeamish when he tries fapping to [[spoiler:Sugawa]] towards the end of the manga, and that makes him realize his feelings.
* CaughtWithYourPantsDown: This is what drives the plot.
* ClaspYourHandsIfYouDeceive: [[http://www.mangafox.com/manga/onani_master_kurosawa/v01/c006/ Done by Kurosawa after fulfilling his so-called duty]].
* [[JustForPun Cumming]] [[ComingOfAgeStory Of Age Story]]
* ADateWithRosiePalms: [[ExactlyWhatItSaysOnTheTin It's even in the title.]]
* {{Deconstruction}}: Very much so, of the typical {{Ecchi}} "protagonist is a pervert but that's ok" genre. [[spoiler: The hero is a pervert, but it's considered a horrible thing, he grows out of it and his life vastly improves because of it, he takes the blame for what he did voluntarily and everyone has a realistic reaction, the tortured girl snaps realistically after years of bullying, including several off-screen suicide attempts]], being a {{Hikikomori}} is considered a ''very bad thing'', etc., etc.
** Although [[spoiler: Kurosawa is still a pervert even after the heart change and facing most of the consequences for his actions, he still masturbates and fantasies about schoolmates in [[strike:college]] High School (just privately). But he stopped being a antisocial, misogynistic and egoistical reject.]]
** [[spoiler: Yes, the problem was much moreso the fact that Kurosawa was very cynical loser and thought very little of everyone else, which is pretty much why any female he knew wouldn't be anything more than a sex object to him, if they were attractive. The whole point of the story is about him realizing that he's wrong, that people are good and having relationships with them is worth it; masturbation was just a metaphor for antisocial behavior in general.]]
* {{Determinator}}: No, Kurosawa [[DidYouJustPunchOutCthulhu didn't punch out Cthulhu]],[[spoiler: [[http://www.mangafox.com/manga/onani_master_kurosawa/v03/c023/22.html he told his Gambit all along in front of his classmates.]]]]And then [[spoiler: took the resulting abuse for the rest of his last year of middle school without complaint.]]
* DespairEventHorizon: Learning that [[spoiler:Takigawa and Nagaoka are going out together]] was already a pretty bad blow, but [[spoiler:doing to her what he did to the other girls]] pretty much disgusted him from everything. [[spoiler:He gets better, thankfully.]]
* EasilyForgiven: [[spoiler:Mostly averted. After he confesses, Kurosawa has to put up with constant harassing and his newly earned "title" follows him to high-school. Takigawa ends up forgiving him, but even her is still shocked for a while and has trouble actually saying it out loud. Played straight with Nagaoka though, but that's in his natural personnality.]]
* ExpositoryHairstyleChange: Kurosawa's bangs get gradually shorter as he undergoes CharacterDevelopment.
* {{Expy}}: Kurosawa looks like [[Manga/DeathNote Light Yagami]]; at least in the first half of the series.
* {{Fan Nickname}}: [[Manga/DeathNote Fap Note]] - The manga itself.
* {{Foreshadowing}}: [[spoiler:"I wonder what kind of feeling it would be to see the girl you like holding hands with another man."]]
* FunnyAfro: Keiji Nagaoka.
* GeniusBonus: "Onani" meaning masturbation is a literary one, as the oldest known reference to the "sin" of masturbation is Onan in TheBible.
* GenreShift: Starts off as a ''Manga/DeathNote'' parody/ecchi crossover with lots of fapping with a slight dark edge in regards to the bullying but a hint of fluffy romance... and then [[spoiler:the fluffy romance turns into a crushing love triangle, the main character getting worse and worse until he realises what he's done and fully admits his crimes causing his rather horrifying and realistic atonement, the first bullying causes the victim to snap and become a suicidal recluse. But [[ReverseCerebusSyndrome they all get better]].]]
* HeelRealization: [[spoiler:Kurosawa, upon seeing Takigawa's painting. He confesses to his actions soon after.]]
* {{Hikikomori}}: [[spoiler:Kitahara becomes one after she snaps. It's not played for laughs nor is it handwaved -- it's mentioned that her mother has had to stop her from committing suicide multiple times, and she's openly terrified for her daughter's safety when Kurosawa comes to visit.]]
* HurricaneOfPuns: Perhaps the oddest example in fiction. It really isn't one in the original language, but when you translate it into English, it becomes a "Coming" of age story about the "Master of Masturbation."
* IfICantHaveYou: What motivates both Kurosawa and Kitahara [[spoiler:to "punish" Takigawa for getting in couple with Nagaoka.]]
* ImportantHairCut: A couple of them - [[spoiler:Takigawa before she entered middle school, and Kitahara at the very end of the series]]. You can also tell that [[spoiler:Takigawa really is dating Nagaoka]] when you see her come to school essentially [[http://www.mangafox.com/manga/onani_master_kurosawa/v03/c018/11.html cosplaying]] [[Literature/HaruhiSuzumiya Tsuruya]].
* JapaneseHonorifics: Nagaoka calls everyone "dono" ("Mister/Madam" or "Lord"). Yes, even [[spoiler:his girlfriend.]]
* KarmaHoudini: [[spoiler:Nobody ever finds out that Kitahara was involved in the incidents; although of course she suffers plenty from the bullying nonetheless.]]
* KickTheSonOfABitch: Actually [[spoiler:masturbating]] over the bitch's [[spoiler:clothes]]
* ManicPixieDreamGirl: Nagaoka is sort of a male example, always cheerfully trying to reach out to Kurosawa, Kitahara and other introvert people in the class. [[spoiler:[[LoonyFriendsImproveYourPersonality It's very important in helping Kurosawa to open up after his confession.]]]]
* {{Meganekko}}: Kitahara
* MentalStory: It's a little plotty, but it's still mostly set in Kurosawa's head.
* MundaneMadeAwesome
* OddNameOut: "Magister"? It's not a nickname or something, you sure?
* ThePollyanna: Nagaoka. No matter how cold Kurosawa is to him, he's always friendly towards him. [[spoiler:[[ThrowTheDogABone Thankfully, it all pays off.]]]]
* RagingStiffie: As usual, [[MundaneMadeAwesome with unnecessary extravagance]].
* RapePortrayedAsRedemption: Lower rating version, {{Narm}}y-capable with [[spoiler:Kurosawa Fap-ed over the two delinquent's uniform]].
* [[spoiler:ReverseCerebusSyndrome:]] Right from the moment [[spoiler:Kurosawa sees Takigawa's painting]], the series gets much less cynical and its main character much more likeable. Although you could also say [[spoiler:metting Takigawa]] was the start of his development.
* SeriousBusiness: Kurosawa takes fapping very seriously, going so far as to call it his "duty".
* ShoutOut:
** To ''Manga/DeathNote'', of course, but then there's also [[http://www.mangafox.com/manga/onani_master_kurosawa/v02/c010/2.html this one]] for ''Anime/CodeGeass'' and a ''lot'' for ''[[Literature/HaruhiSuzumiya The Melancholy Of Haruhi Suzumiya]]''.
** Late in the manga, a couple of kids are [[http://www.mangafox.com/manga/onani_master_kurosawa/v04/c029/4.html playing the E-Card game]] from ''Manga/{{Kaiji}}''.
** There is also a Shout Out to [[http://en.wikipedia.org/wiki/Gag_Manga_Biyori (of all things) a rather weird anime called Gag Manga Biyori]], depicting Kurosawa as the perverted bear Kumakichi.
** [[Literature/TheCatcherInTheRye Catcher In The Girl's Bathroom]].
** How about a GenderFlip of the ''Manga/DeathNote'' movie called ''[[FoeYay Les Note]]'', starring Eru Ryusaki and Lunako Yagami?
** [[http://www.mangafox.com/manga/onani_master_kurosawa/v01/c007/3.html Early on]], when confronting Kitahara from inside stall, he expresses a wish for a [[Manga/DetectiveConan voice changer]].
* SlidingScaleOfIdealismVersusCynicism: As it starts out as a ''Manga/DeathNote'' parody, it begins pretty far on the cynical end of the scale, starting of with a showcase of humanity at its most dickish, misanthropic, and cruel. [[spoiler: It ends far, far on the ''other'' end of the scale, with an unflinchingly optimistic message about taking the high road, friendship, inner strength, and forgiveness, with even ''Kitahara'', after all the hell she goes through and inflicts, making it through her shut-in phase with Kurosawa's support.]]
* SpellMyNameWithAnS:
** The series' title, specifically the word "onani" due to different modifications to Hepburn Romanization and the debated status of the proper romanization of elongated vowels sounds. The dropping of the long vowel is the most common interpretation amongst the fanbase.
** Takigawa has her last name constantly misspelled as "Takagawa".
* ThirdOptionLoveInterest: So does Kurosawa end up with Takigawa, who he had a crush on, or Kitahara, the one he eventually [[DefrostingIceQueen defrosts]]? [[spoiler:Neither of them. He actually ends up with Sugawa, [[AlphaBitch the bully]] and his first victim, since by the time they start getting together, she has become much less mean and more {{Tsundere}}.]]
* {{Title Drop}}:
** Contrary of what would you think, [[http://www.mangafox.com/manga/onani_master_kurosawa/v03/c024/15.html is not really a funny moment when it happens]]. With a title like that, how could it be?
** Including [[spoiler:Prince of Cum]] [[http://www.mangafox.com/manga/onani_master_kurosawa/v03/c024/14.html no less]]
* {{Tsundere}}: Sugawa
** {{Lampshaded}}: "Sugawa is so... how's that word [[{{Otaku}} Nagaoka]] taught me? Tsun... tsun... baka?"
*** Also could double as a ShoutOut to a one shot by the author.
* VillainProtagonist: as a part of Expy-ness for [[Manga/DeathNote Light Yagami]], Kurosawa is one....[[InSPACE BY JACKING]] ... At first.
* WhamEpisode: [[spoiler:When Takigawa and Nagaoka are revealed to be dating.]] The cries and shouts of unsuspecting new readers can still be heard in various sites to this day. The series just takes a [[GenreShift completely different turn]] from that point on.
* {{Yandere}}: Kitahara
* YouBastard: Aimed right at the readers who were ''cheering'' the main character on, once he basically makes a 180.
