Masturbation. That's what kicks this story off, male masturbation. You might think; why the heck is this manga getting such high ratings when it involves masturbation? Simple answer; Onani Master Kurosawa is the best completed, and feel-good manga I have ever read that will forever be remembered.
This manga will make you feel sad, make you feel happy, make you feel disgusted, make you feel justified, make you feel sympathy; this manga has it perfectly tied up. So you're finally interested? Then let me tell you what this manga is about.
Kurosawa is a high school boy that doesn't do much in life. He hates interacting with people, and even his so called 'only friend' in his class he actually secretly dislikes. So he hates people, that's a given. At school, at the end of the day, he will go to the girl's bathroom in an empty school part, and start fantasizing about his 'victim', which will be a girl he had his eye on for that day. He will imagine doing the dirty deed with her and masturbates to it. After he finishes up, he makes sure no one saw him, because that would be disastrous. He will repeat this a few days, until one girl finally figures out what he does in that empty bathroom stall.
This girl is called Kitahara and gets bullied. A LOT. Kurosawa notices she gets bullied every day by 2 other girls. Eventually they bully the girl so much the entire class is laughing at her, and Kurosawa can't do anything but watch. He's angered; he wants to punish those girls for bullying a girl who can not stand up for herself. So he ... steals the bully's gymclothes and masturbates to get semen all over it (don't ask why, he thinks it's a fiitting punishment). He then puts the clothes back into their bag. The game has begun.
Now here comes a bit of spoilers, so don't read further if you don't want to be spoiled of the first 5 chapters or so.
Kitahara confronts him when he just finished his daily masturbation session. She stands outside the bathroom stalls and tells him she knows he is in there. Kurosawa is scared out of his mind and pretends he's not actually in the room. Kitahara keeps on talking to him, telling him that she knows it was him who ruined those girls' gymclothing. She asks for a favour, she wants him to do it again to another person who bullies her ... in return for keeping quiet about his daily happy hour. And so the blackmailing begins as well.
This manga deals with bullying in the most realistic degree. The masturbation stuff is merely a plot device to help propel the compelling story about all these classmates. Heck, in even later chapters, masturbation is barely even mentioned. It is all about the classmates and how they interact with each other, try to bully people, try to punish people, try to apologize, try to become better and eventually they finish high school.
Onani Master Kurosawa talks about every minor character and develops them so well, it's unbelievable the amount of character development everyone in this manga gets. Of course the main character gets the most (you'll cheer for him in the end), but even the bullies themselves get some development.
You will be in tears of joy once you finish it. This masturbation ridden manga is a beautiful story. You have to read it; you won't find anything more finished and complete than this slice of life manga. I recommend it to everyone, even those who think the topic of masturbation is icky. You just can't miss out on this great manga.
You might read other reviews here stating that it's a Death Note parody, they couldn't be more wrong. There's one page in this manga that's a parody of Death Note, and that's it. It's just a pose the main character makes, the rest is all original story, so really, give it a try, you won't be disappointed.
