Describe Onani Master Kurosawa here.

It's Death Note but with fapping.

Hey, you asked.

But seriously. Onani Master Kurosawa (lit. "Masturbation Master Kurosawa"), by Takuma Yokota is about Japanese middle student Kakeru Kurosawa, a cynical misanthrope who makes a daily ritual of slipping off to masturbate 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 constantly bullied by the more popular girls in class until Kurosawa imposes justice onto them by—yes—masturbating onto their clothes. 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 The Catcher in the Rye-ish. And that's just about all that can be said without going into spoiler territory.

Being done as a voice drama here. There is also an after-story of sorts here and here. A mini comic depicting humorous scenes not previously shown can be found here courtesy of this deviantart user here.

Not to be confused with Strongest Legend Kurosawa.

This series provides examples of:

  • Aerith and Bob: Aya, Keiji, Ryuta, and Erika, meet Magister.
  • All of the Other Reindeer
  • All Just a Dream: ALL of the Ecchi scenes are Kurosawa's Wild Imagination.
  • Anguished Declaration of Love: Subverted in a chest-stabbingly cruel scene. 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.
  • The Atoner: Kurosawa after admitting to the class what he did, and getting bullied for it.
  • Batman Gambit: This one is exceptionally played.
  • Beware the Nice Ones: REVENGE! Kitahara just does it, making a somewhat terrifying image for Kurosawa (and some readers).
  • Birds of a Feather: Takigawa and Nagaoka. As much as Kurosawa hates it at first, he eventually admits that these two are made for each other.
  • Bound and Gagged: Happens to Sugawa in one of Kurosawa's... fantasies.
  • Break the Badass: Kurosawa, upon seeing Takigawa and Nagaoka together.
  • Break the Cutie: Kitahara again, in a terrifyingly realistic way.
  • Can't Act Perverted Toward a Love Interest:
    • Kurosawa gets sick when he first tries fapping to Takigawa.
    • Later gets a bit squeamish when he tries fapping to Sugawa towards the end of the manga, and that makes him realize his feelings.
  • Caught with Your Pants Down: This is what drives the plot.
  • Class Reunion: The climax of the story centers around Kurosawa bringing Takigawa to their middle school reunion party, after she becomes a shut in. One of the bonus strips done after the manga's tenth anniversary also has Kurosawa's class meet and catch up at one of these.
  • Deconstruction: Very much so, of the typical Ecchi "protagonist is a pervert but that's ok" genre. 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 Kurosawa is still a pervert even after the heart change and facing most of the consequences for his actions, he still masturbates and fantasizes about schoolmates in college High School (just privately). But he stopped being a antisocial, misogynistic and egoistical reject.
    • 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 didn't punch out Cthulhu, he told his Gambit all along in front of his classmates.And then took the resulting abuse for the rest of his last year of middle school without complaint.
  • Despair Event Horizon: Learning that Takigawa and Nagaoka are going out together was already a pretty bad blow, but doing to her what he did to the other girls pretty much disgusted him from everything. He gets better, thankfully.
  • Easily Forgiven: 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 she 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 personality.
  • Expository Hairstyle Change: Kurosawa's bangs get gradually shorter as he undergoes Character Development.
  • Expy: Kurosawa looks like Light Yagami; at least in the first half of the series.
  • Finger-Tenting: Done by Kurosawa after fulfilling his so-called duty.
  • Foreshadowing: "I wonder what kind of feeling it would be to see the girl you like holding hands with another man."
  • Genre Shift: Starts off as a Death Note 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 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 they all get better.
  • Heel Realization: Kurosawa, upon seeing Takigawa's painting. He confesses to his actions soon after.
  • Hikikomori: 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.
  • Hurricane of Puns: 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."
  • If I Can't Have You…: What motivates both Kurosawa and Kitahara to "punish" Takigawa for getting in couple with Nagaoka.
  • Important Hair Cut: A couple of them - Takigawa before she entered middle school, and Kitahara at the very end of the series. You can also tell that Takigawa really is dating Nagaoka when you see her come to school essentially cosplaying Tsuruya.
  • Karma Houdini: Nobody ever finds out that Kitahara was involved in the incidents; although of course she suffers plenty from the bullying nonetheless.
  • Manic Pixie Dream Girl: Nagaoka is sort of a male example, always cheerfully trying to reach out to Kurosawa, Kitahara and other introvert people in the class. It's very important in helping Kurosawa to open up after his confession.
  • Mental Story: It's a little plotty, but it's still mostly set in Kurosawa's head.
  • Mundane Made Awesome
  • Odd Name Out: "Magister"...? It's not a nickname or something, you sure?
  • The Pollyanna: Nagaoka. No matter how cold Kurosawa is to him, he's always friendly towards him. Thankfully, it all pays off.
  • Raging Stiffie: As usual, with unnecessary extravagance.
  • Rape Portrayed as Redemption: Lower rating version, Narmy-capable with Kurosawa Fap-ed over the two delinquent's uniform.
  • Reverse Cerebus Syndrome: Right from the moment Kurosawa sees Takigawa's painting, the series gets much less cynical and its main character much more likeable.
  • Serious Business: Kurosawa takes fapping very seriously, going so far as to call it his "duty".
  • Shout-Out:
  • Sliding Scale of Idealism Versus Cynicism: As it starts out as a Death Note 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. 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.
  • Spell My Name With An S:
    • 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".
  • Third-Option Love Interest: So does Kurosawa end up with Takigawa, who he had a crush on, or Kitahara, the one he eventually defrosts? Neither of them. He actually ends up with Sugawa, 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, it's not really a funny moment when it happens. With a title like that, how could it be?
    • Including Prince of Cum no less.
  • Tsundere: Sugawa.
    • Lampshaded: "Sugawa is so... How's that word Nagaoka taught me? Tsun... Tsun... Baka?"
      • Also could double as a Shout-Out to a one shot by the author.
  • Villain Protagonist: As a part of Expy-ness for Light Yagami, Kurosawa is one... BY JACKING... At first.
  • Wham Episode: 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 completely different turn from that point on.
  • Yandere: Kitahara.
  • You Bastard!: Aimed right at the readers who were cheering the main character on, once he basically makes a 180.
