Great story flow

When I first started reading this manga I thought it was going to be a slapstick comedy the whole way through, but turned out to be a deeper story.

The author did a great job of making a roller coaster of emotion with a great flow. Everything felt like it fit, and there were no super abrupt changes in mood, rather a gradual change.

My one complaint would be that it seemed like the manga was slightly rushed in the last volume, it really felt like the manga could have gone longer.

I read this like 12 years ago. I was cleaning up my library list and bump into this, even now i still fondly remember this manga.

Art style might not be for everybody but i find it unique.

As for the story and characters, i'd rate it pretty high. Its about a bunch of students, their coming of age story, maturing into young adults and coming into terms with reality. The characters feel human and relatable. Handles a lot of real themes like bullying, social withdrawal, unhealthy habits, human relationships, unrequited romance, regrets from making bad decisions but learn to face it, reconciliation and to forgive so we can move on.

I'd say don't be discourage by its weirdness, especially the title. Its a really good manga.
There are some who are dismayed by the pairing(which girl our protagonist ends up with) but i feel like its the most realistic. Eventhough its unexpected. While the ending, i dunno how to describe it, maybe bittersweet(for all the characters)? Basically the pairing and conclusion was neither the best nor the worst, its flawed but thats why its perfect because thats how life is.

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.
