This is the greatest thing I've ever read.
I've seen a lot of discussion about it and even watched Murata's livestream of him drawing frames, but I only got around to actually reading it yesterday, and boy, what a ride.
I honestly though the plot of beating enemies in one punch would get old pretty fast, but it's incredible how well it's been handled to make it interesting even 40 chapters in. Really love the variety of characters, both in personality and designs.
If you're like me and haven't yet gotten around to reading it yet, do yourself a favor and check it out.
