It's been a few years since I read this but, it is one of the most outstanding mangas I have had the pleasure to read. The story shows the MC's progress from hateful to opening up to others and really redeeming himself for the sake of being a better person. I honestly do like the girl he ends up with (the omake and extra side novel chapters really are great to read as well) as she kinda brings a foil to him.

One of the series I really wish had more omakes or even a slice of life sequel because I love the characters so much.

Had a cathartic ending, and I really liked the chemistry between the MC and the girl he ended up with. SangMo is unbelievably w r o n g when they say it gets worse after a certain event. I’d say that’s when it becomes the most heart wrenching.

But sadly 1 moment destroys it and it's all downhill from there.

Spoiler (mouse over to view)
The girl who he likes & has great chemistry with starts dating the annoying afro guy

After that moment, the manga takes a turn for the worse. I've seen it happen in other manga's before and while some might disagree, I found it to be very jarring and not very good.

Spoiler (mouse over to view)
After she starts dating afro guy, it shows there's no hope he has a chance with her. You think maybe it's pushing him towards the introvert girl who knew his secret, but nope. He's randomly pushed upon one of the first girls who he got his "revenge" on, this popular bully girl. He loses the girl who he had the best chemistry with to such an annoying character.

That one moment seriously turned the rest of the manga into a mess.

I love this one. I thought it will be a weird, Durarara-type manga, but it reminds me a lot of Watamote.
There isn't anything weird, it is simply the mind of the protagonist that is weird. Those things happen everyday, but the way he sees the world around him is what is exciting.
I loved it.

Pleasant Surprise

So I picked this up not expecting much, mostly because 30 chapters or so didn't seem like it would take very long. I'm really glad I read this though since it managed to tell a very nice tale of a young man learning to grow up. Not your normal coming of age story to be sure, but one that comes across as surprisingly powerful throughout. There are some moments of heartbreak in this story that feel so raw and real it almost hurts.

Really one of the best things about this manga is that it feels like the author actually sat down and planned out his series beforehand. So many mangas out there have pointless chapters or events that seem to artificially add drama, this story on the other hand felt very well paced. The ending was also both well done and a bit surprising, I like it when I can't see the ending from a mile away.

Minor complaints are the only thing that lower the score here. For one I do wish some stuff was wrapped up a bit better with the side characters, and to be honest another chapter past the ending would have been very appreciated. I know there's a sequel novel out there, but it shoulda been in the actual manga.

Surprisingly good read.

Onani Master Kurosawa is a weird little piece of work. Many compare it to ?Catcher in the Rye? or ?Death Note?, but I found it a bit more like the movie ?Mean Girls?.
Only it?s about a middle school boy masturbating to fantasies of his classmates.

It tells a story about how people can change over time, importance of social connections, and how different characters deal with their emotions.

The art style is pretty cool as well.

Totally recommended. If you can get past the admittedly gross theme of masturbating.

Try it. Just try it. It's not just a cheap thrill, this is a real masterpiece. The author's other work Molester Man is a great read as well (don't be put off by the name of that one, that one has even less to do with xxx stuff than this one does lol).

It's not really an ecchi manga, but really a coming-of-age story. I urge you to read the first couple volumes before you decide whether or not to give up on the series.

A lot of manga is revolved around the fictional tales of what girl in school have to go through. They rarely show such thing with a boys view and life perspective. Such an awesome read. I'm glad I looked passed the title to read this. Art is fitting too.

(Spoiler has beginning to end)

starts about a boy that has an unusual fetish for sneaking into the girls washroom at school to jack off. He thinks about girls at school and fantasizes about them while he does it too. Besides that there is a lot of bad bullying going on in class towards this one girl. He sympathizes with her and helps her out by humiliating the girls in the way he knows best. He cums on their stuff. That is where the story takes off. He then is forced to continue doing it because the girl he helped ended up blackmailing him to do more because she knows of his secret. He does it a series of times more. It doesn't stop him until one of he good looking girls in class catches his eye and he falls for her. She ends up being not for him though and he feels resentment towards her because of that. It is after he end up doing the same thing to her is when he really starts to regret what he did. He ends up coming forth about his actions and gets extremely bullied for it months before he is done middle school. Slowly everyone starts to forgive him though. Even after middle school he ends up getting closer to one of the original bullies . She still has a horrible mouth but she falls for him too. Great ending.

Wonderful story, albeit revolving around a bizarre theme. I loved all the characters and the ending left a super warm, fuzzy feeling in my heart. I am not going to forget this one any time soon smile

I thought I'd just read the first chapter just to see what it's all about.

Few hours later, I'm done.

What a manga. As a girl, seeing some young teenage boy fap to really sick, perverted illusions of girls is a far cry from something I'd want to read about. But the character development he goes through is excellent, and the lessons he learns are something that the protagonist of any regular run-of-the-mill harem manga would never think to learn.
