i was fooled by this manga's title, my 1st thought it will be a full ecchi manga, but after read half of the chapter, i was wrong! the story really awesome, but the main aspect that i'd like to share is friendship, no matter how other people treat you, there's always someone cheers you up (my wise words)

I ignored this manga for years, mainly because of it's title, but today the curiosity got the best of me and I read the whole thing in a sitting.

My opinion? It's good. Don't be deceived by the theme or the title. Some resolutions aren't very fulfilling, but it's a solid history overall.

Now to the followup novel.

I found the story quite good. I never expect it contained so much drama the first time I saw the title. However it could have been better if..

that Kitahara chick confess to the other students in their class that she's also a partner in crime with Kurosawa. Rather than just watching Kurosawa shouldering the blame alone, she should confess too.
She said that she's not that strong compared to Kurosawa, but I think if she ever confess, at least the bullies know whatever Kitahara and Kurosawa doing was actually an event that occured because of what the bullies have done.
Throughout reading this series I can't help but wonder when will Kitahara grow some backbone and help clearing the situation she put Kurosawa in, or fight back the bullies rather than inflicting pain on her own body.

Still, this is worth reading.

It always becomes a game with me, trying to guess when the author will quote J.D. Salinger or Catcher in the Rye. All authors that write these types of stories eventually do. (There are a few in here, if you care to play along.)
The characters are pretty well thought out, I loved Yokota Takuma's rough sketch-like drawing style. It starts out really rough, but it gets a bit cleaner later on.

I decided to read it because I wondered how in the world something that's titled "Onani Master Kurosawa" can have such a high rating. To me, that means either it's hyped up or it must be really good. And wow, it did not disappoint. The story starts off slow and seemed like it might be an ecchi manga. The crude drawings didn't really help either. Basically, volume 1 was a little boring. But, as the main story takes off, you're taken on an emotional roller-coaster.

There are friends and enemies. Actions and consequences. Crime and redemption. Hate and forgiveness. I read through it all before I realized it. The story was masterfully told. Even Kurosawa's perverted thoughts didn't feel perverted, just honest thoughts of a teenager boy who was perhaps a little confused. My only gripe is that I wish it was a little longer for my own enjoyment. But in reality, it was probably just right.

thats all. If you ve gone past puberty, if you had already decided your next direction in life, its quite likely you wouldnt be able to relate to characters in this story. But who that does will definitely love it (this manga is ranked pretty high afterall).

The art is kinda strange, being pencil drawn, its detailed but the cutegirls' faces are too generic to my taste. And the story takes off so slow, I skipped almost first half of the chapters :\

A manga masterpiece   
Rating: 10.0 / 10.0

Funnily enough, I'm giving this manga a 10/10 and I really don't know why. Honestly, the art isn't all that good, the story falls victim to copy-paste character referencing and lingers upon a perverted border of being misleading for readers.

However, before you're put off, I will say that the manga itself performs so well that the aforementioned problems are immediately overridden by a deluge of the raw emotions of a great story with a large space to fill the reader's sympathy with.

The story itself starts off shamelessly, and rather humorously, with the ever-so taboo subject matter of masturbation purely taking the center stage in the first volume, but quickly descends into a cesspool of raw feelings and human emotions conveyed by ridiculously realistic characters before tearing apart your heart and then piecing it back together. Plot twists also show unfathomable realism, such that the chances of predicting what happens next fall to record lows. The orgasmic climax of the manga fits it, without giving the reader too much despair. You will, however be left with feelings that will carry weight for a lifetime and find yourself thinking about the manga for a good week or so.

However, one could say that the characters fall victim to stereotypes and schemers of the human mind, but after great character development coupled with their ever-so-unique personality attributes, the depths of their inner psyches are such that they can be described as nothing but realistic.

The art itself is rather unprofessional, mainly because it is. But despite its lack of prowess, one can confidently say that it does its job. Characters are immensely expressive, very recognizable and have suiting visuals to their personality, while the backgrounds are almost non-existent. The sketchy style suits the sour premise of the manga, but can be a little unbearable for readers used to higher quality.

Now that the outrageous rating has been ambiguously justified, I can personally say that it is the greatest manga I've read so far without a gram of exaggeration. An instant favourite of literature. A showcase of humanity's prowess.

If you haven't read it, stop whatever you are doing, throw away shame and shyness and start reading the first chapter wherever you may be. It's really that good.

This manga really isn't for everyone, but I think it definitely has an audience that will identify with it and really appreciate it. Personally, I loved it, but I'm a sucker for coming-of-age, Catcher in the Rye stuff.
I'll start with what I didn't like. The beginning dragged. Granted, the beginning needed to be long because there's quite a bit of exposition and buildup, and I can't recall any particular chapter being totally useless, but the beginning was pretty long and unrewarding nevertheless. Also, the protagonist's turn-around is pretty darn quick, and his (eventual) maturity is more similar to that of a high school or college student. I get that middle school is a time for change and development, but Kurosawa's development was unrealistically fast.
Now, the good. The climax of this manga is just so good. The problem with a lot of narratives is that characters don't face the consequences for their actions. Kurosawa is a different case entirely. On a related note, seeing him realize that hating the world doesn't make you superior; it makes you miss out really hit home for me. It's just such a great realization to make, and one that I think is pretty appropriate for his age (again though, not a huge fan of how hyper-maturely he handled himself post-epiphany). Finally, despite its pretty outlandish premise of two outcasts being jizz terrorists, Onani Master Kurosawa does a really great job of dissecting of very real concepts such as loneliness, social isolation, and the human condition in an understandable and relatable way. Onani Master Kurosawa's strength is that it makes you think and reconsider your perspective, which, to me, is enough to warrant a look (just remember to trek through the beginning and get to the climax--so worth it).

ok i wrote this comment after reading chapter 16:
Spoiler (mouse over to view)
chapter 16, we get to know takagawa's true feelings, and the favor from kitahara. the favor was really expected but, just wow, making it happen really felt different.

from a male's point of view that's really a huge heartbreak

also, feeling disgusted about

fapping to a girl you like is just so true, especially at that age. boys may be generally horny beasts but when it comes to the person you love we really have so much respect.

gosh im only at half of the manga and i feel like reading this is one is such a memorable experience

now i finished reading it:
Spoiler (mouse over to view)
so i said a while ago, i thought takigawa's "true feelings" was takigawa liking kurosawa. i was dead wrong. it hit me like a truck, that kind of stuff really happens. "Mistaking her kindness for feelings of (even a little few) love", ive had my fair share of that from real life experiences. Sadly, seeing takigawa and nagaoka together was painful. Makes sense that Kurosawa's heart broke down. after that part, the story went darker, although i kinda didnt like that part, esp when kurosawa did those stuff to takagawa. It doesnt really justify a broken heart.

Then comes the most exciting events in the manga, our main character saw that work by takagawa, and he entered "shounen" mode. He manned up and faced all the consequences of his actions. Yeah thats the "shounen way". And i was really happy, but it didnt stop there. There's still the Kitahara problem and i have no idea how it will be going to resolve. But im pretty sure, the main character will go "shounen mode" again and help the poor Kitahara. So yeah he did it and manga ended. Kitahara gets the most of my sympathy the whole time. Although help came in really really late, she deserved that kind of happy ending. So now everyone happy, and Kurosawa gets a bonus chapter.

Your average Harem Ecchi Romance heroines have nothing compared to how cute, charming, and lovable

Takagawa and Sugawa
are. Seriously they are the ones who deserve "waifu" titles haha.

I originally read this because of the title. There's been a few ecchi series I picked up just because it made me stop and think "what the hell is this?" and I'd really enjoyed them! The tags were a lot different on this one, but I decided to chance it.

It was alright, but it wasn't really that great. The original premise was interesting, and for me, the real strength was in how the mangaka handled Kurosawa's character development. It was set up well, and it was nice to have a satisfying sense of resolution after everything that went on.

However, the ending felt kind of patched together in a disappointingly poor show of formulaic seinen romance. I also felt like the subject of bullying was handled pretty poorly, since Kitahara pretty much existed to take the fall and make Kurosawa's character more likeable to the reader. Even her depression and other personal issues ended up being used almost exclusively to make him look good, while she remained distressingly "bad" until it was time for Kurosawa to save her from herself.

So, worth the read, but after the main arc powers down, the story just goes stale.
