i thought it was going to be about some preverted kid (it is) but it's not just that. I like the art and the story plot is getting really interesting. I may boost up my rating after getting further into the story.

from what ive read so far (5chapters), this author most definitely did not intend his manga to draw a wide audience. It's based on a school boy with a less than common or normal habit(aka fetish). the story is somewhat promising and i believe the author can still make this into something that can be widely accepted and enjoyed, however, speaking from experience, I have a feeling the story will go on a path to insignificance, ultimately ruining its quality and being left in squalor amongst other trash works that people normally give up reading along the way.... of course im being harsh but since such scenarios are common, i will not retract my words. God forbid i hope the author does not finish his manga on the weird fixation of the main character because that would be like beating a dead horse over and over and over again. If the main character can develop into something, and the manga becomes something more than a focus on his weird habits, it can turn out to be great. so far i would give it a 6

Yes, you heard that phrase. The description may sound stupid, and yeah, it does sound stupid and is a waste of time to read. But no, its not. And I am glad I read it. The story has real drama, it has a seinen feeling in it. Yeah, its basically about a guy who got caught jacking off. Its a girl who caught him, and that girl constantly gets bully. Though you might not be fond of its drawing style, since it looks kinda "messy", but I like it personally. As people said below, its similar to Death Note (you'll see why when you read chapter 5. =P) Anyway, its really good to read. I recommend it, read it now!

this manga seems really deep, the fourth chapter seems to show this manga as a more intelectual manga. It seems like a combination of death note and the world only god knows. Yet, unlike death note, the hero seems to act on redemptive qualities, and unlike twogk, the story is more pragmatic and deeper. The hero exhibits thought that are unpredictable and profusely profound... I like where the manga is going. It has alot of potential.

As of chapter 23: unlike death note the main character has decency, it's as if we had a nice kira all along. I want to see where this is going. Also, the sketchy form of art is perfect for this kind of dark manga.

Amazing Series

I am almost done with this series and I have to say this is one of the most enjoyable mangas I have read in a long time. Needless to say this is an extremely unique read with a story I guarantee you have never heard before. The characters are extremely well developed to the point where you can really feel the emotion between them when they interact. I really cannot stress enough how different this series is from anything else I have ever read. Its a shame it is only 30 chapters, but I really look forward to seeing what else this author is going to do.

well, it's early in the series so it's hard to pass judgement.
oddly enough, the main character DOES remind me of light from DeathNote a bit...i cant quite figure out why though...(the thought of Light doing things like this kid does brings about very disturbing imagery).
but i think the concept itself is hilarious and i look forward to reading more bigrazz

Even if the jokes about this manga being the "Fap Note" aren't your thing, you should probably try it out. The main character is a bastard at times, yes, but the way he narrates things is quite nice, since he's an observer most of the time. There's also nothing explicit if you don't like that, either.
I have to make a point about the awesome drawing style (it might not be everyone's cup of tea, but I find it awesome).
You can either take this as a pure comedy with some naughtyness added or it might make you think about some of the things going on (the typical bullying, to name something). I think this manga has a little bit of everything.

it's good, although the concept & character are near to Death Note, but when i read first 4 chapters, it had great potential to become very good!

can't wait to

art is quite good though

i was going to pass this up after reading the description. but luckly, i scrolled down and noticed that this manga got a 10 almost universally from everyone. so i read the first 4 chapters (all that's out at the moment), and i think...

this manga is about much more than what the description implies. it dives deeply into the thinking of the main character and his thoughts on what's happening around him (reminds me of kurono from the beginning of gantz). the whole school life thing is also understandable from everyone considering we all lived it at one point in our lives. not many chapters so far, but i really hope this one develops nicely because it's got a ton of potential at this stage.
