This has to be the best manga I ever read by far. The story is in the title. man who can beat anyone in one punch. You have to give this a try. This is actually a remake of an older version (Which the art work and the story wasn't as good as this is) Its action/comedy and it balance out pretty well.

it looks cool, i'll give it a shot.

Did anyone else check this out? Sorry to bump but I'm reading this as well and it's actually pretty cool.
I may just be a picky bastard, though, I kinda feel like this started off as a joke and the story was improvised along the way and as it gained a following it started getting more and more serious, but it's finally getting to a point where the story might actually get interesting.
I could be wrong but in any case it's pretty entertaining and funny. There isn't a lot of it done yet so if you wanted to catch up you could do so pretty quickly. Do it guys, do it.

I recommend this manga very highly. The art is amazing, it has a ton of funny moments, and the premise is actually pretty interesting. The story may seem stupid at first, but over several chapters it really starts to pick up.
