Doesn't Kurosawa in this panel look a bit like Neuro Nougami?

Very good

I had seen this discussed many times on forums and the like and never with a bad review. Indeed all the people that seemed to have read it said it was simply one of the best manga they had ever read.
Thus i went into this thinking it would be the best manga ever. Unfortunately, it did not live up to the hype. Don't get me wrong, now. It is very good. Excellent. There's just one thing that doesn't make sense to me...why didn't they do a dna test?

The ending respects slice of life, which is to say, life, very well. i don't want to say too much, so i'll just say that it was really very realistic.

I actually just finished reading it a few minutes ago and felt the need to post something up here, so i'll fix up this comment after some sleep.

In short: definitely do read. It may not be the best ever, but it's realism and character development is really exceptional.

I can't deny that Onani Master Kurosawa is THE best manga I have ever read. Hell, it is one of the best stories I've ever read, and I'm a real bookworm. This manga made me feel so many emotions, made my heart skip a beat, had me so wrapped up in the characters and the plot, I've never felt that involved in a story before and I may never again. This manga is so mature and dramatic, the characters and the conflict are so well developed, and only within about 30 chapters (I think). I've recommended this to people in real life; eventually I only convinced them to read it on a dare, but every person I know who has read this (some were manga fans of many different tastes, and some had never even read manga before) have enjoyed it and became as emotionally involved in it as I have. I HIGHLY recommend this manga, no matter what preconceived notions you may have about the subject matter!

Masterpiece~

Honestly, i find masturbation as a way of growing up, but in some cases it also can be accepted like a way of escaping from reality. A lot of persons that have this habit can not control their emotions or thinkings, just like Kurosawa, who was a lonely soul~

I really like this manga, at the start i was like "this is weird~!" but then all was a great way of passing time. I learned a lot and i hope everybody thinks the same. You have to!

Very glad I read this one~ Really recommended~

wow... much 'deeper' than the title makes it out to be.

Kurosawa just grows on you... his habit of masturbating is to make him seem like a disgusting individual, yet you quickly realize that he's a better person than most of the other characters.
they are all young middle schoolers, who are looking for themselves and their place in the world. they are all looking for self-satisfaction while at the same time to be liked by everyone else...

simple manga. short and sweet. good read.
recommended for anyone looking for a nice "character growth" manga

Awkward premise but told beautifully

While the synopsis might make you stop and reconsider reading this manga, please don't. Reading this manga has been one of the great experiences that don't come too often when going by on your daily routine of picking which new manga to unravel. It's told in a splendid way which makes it flow, and since it's short can be read in a 1-2 hour session. Characters and story work well together with unexpected twist coming along to thread the whole plot which works surprisingly well.

Never had any problem with the art and I actually kind of like it. The main character looks badass at times and the girls are really cute.

Props also go out to the translators since everything was easy to understand and clean.

A masterpeice created by Doujin and begin with a kinda sick idea!

When I decided to read that manga I never expected something like this, I come to this series while searching for an Adult series and it's stand out as one of the highest rated manga. But I dropped after reading its description, I thought What the hell I will read a manga about a boy masturbate. I picked it up again after my friend strongly recommended it to me and well, it's really really a good read. Even though I must say that those first couples chapters is really dull, protagonist had kinda dirty obsession but I don't think it's so unrealistic, I make sense in the end of the story: "All middle school students are children." yeah the author overdid it a bit but it was solved well.

Although calling it as a masterpiece maybe overate it a bit but the last part of the manga is awesome. Both the ending in chapter 30 and extra chapter 31 is outstanding, I have read 100+ series but they are one of the best chapter I have ever read. The fact make it great not only because of the character development, the plot, stunning moment, suitable art, interesting romance but also the way the author created the story line, switch the time line a bit and the way he express Kurosawa thought, it makes the story dense and toughing, I was totally hooked by it.

I hate that the mangaka nowadays try to lengthen the story to 100+ chapter after it earn reputation but most part is not make sense at all, maybe because the author is Doujin so he is not affected by this fact. I'm looking forward for his other work in the future.
The only thing I dislike of this manga come from the point that I dont like light novel (its unnecessary 18+ , the way it introduces those girl... then the protagonist choose them...blah...blah) , and this story was made as one of them. Anyway, it's not bad at all.
Believe me, try to sit after the first half of the story, the second half will be of the best u have read.

Wow..... i mean.... wow.... It was so amazing, quite a read. I have never experienced the assortment of feelings I had while reading this manga form any other manga.

At first I felt psychologically disturbed as someone had put it, I also laughed a lot at the whole "Fap Note" joke, I felt amazed by the characters and especially one part I was crying at how one boy treated him so well. The last part was really good too, I was happy with who he ended up with in the end... I just felt like the romance was unsatisfying in the end, I wanted maybe another chapter to show more romance (since it was the whole reason I read this manga) however, even though I wanted romance so bad I was quite pleased with the main story and how liberating the characters were.... Simply amazing... amazing is all I can say, what a masterpiece in character development and a significant representation human psychology, courage, and the problems we encounter in a social/cultural context.

How is this not a good manga. There is no justice at all in this, it's an act of human relations. I recommend this manga, if your looking for a story that has more in-depth that it first appears. And this story now matter how similar it can bare resemblance to is not shallow or clique, I can tell you that much.

A niche manga for a very specific group of readers, yet undeniably impactful

by Yin_no

Rating: 9.5 / 10.0

Umm.. well ^^; one thing I can say for certain is that this manga was intended for a male audience.

Initially, the theme of this manga may seem very inappropriate and disorderly, but after reading the entire manga, it kind of leads the reader to a new perspective on the manga and its theme/message.

Though short, this manga really goes through several stages within the chapters, mostly going from Acting based off of sexual desires -> Being caught and paying for the Action -> Finding love and rejecting his previous methods -> Losing that love, hence losing the one hand in his life that seemed to be reaching out to save him -> Retribution in a form of revenge and pettiness -> Coming clear about everything, trying to change -> Dealing with the consequences met from his past actions, still trying to change and mend relationships he destroyed -> Somewhat moving on/becoming a changed person, with the others around him being supportive -> Helping out the FMC find change herself -> Not dwelling on his past love and moving on, finding new love.

Now, while I don’t think this manga was a masterpiece by any means, and it definitely had many flaws to its plot and story, I think there were many parts that I did find to appreciate. Quite similar to Aku no Hana as well in retrospect.

Honestly, I don’t think this manga would be much of an impact to the majority of the audience, but to growing up teenage males struggling with puberty and keeping up with the constant changes in life, I think this manga could give a new perspective on how to deal with such issues.

(nostalgic) masterpiece

Rating: N/A

Back in the day when we were kids, we read this series and got angry at

his crush dating another guy , we were frustrated when ! he publicly confessed and decided to repent instead of continuing his vengeance arc , we were devastated when he ! started dating the girl who was the main villain of the first few chapters . Those feelings are natural if you're used to the type of one-dimensional hero/villain stories that dominate the mangasphere. If you don't want to read the spoilers, just know this: this isn't a series about childish revenge fantasies and righteous punishment for school bullies. It's a story about how who you are in middle school is just a microscopic portion of your life, and you get to choose how long that person stays with you. It may sound ridiculous, but more manga should emulate themselves off of this series about a guy who dramatically jacks off in the girls' restroom every day.
