Right now I'm reading the newest volume of I Am A Hero. No doubt the very best zombie story I've ever encountered. I felt real fear at some of the moments in the manga. Plus, the art, where I typically don't enjoy hyper-realistic art, feels right at home in the story. My favorite part though is that it doesn't glorify Japan as most manga/anime do. It depicts it as a country of greed and perversion. While it might not be true to the extent that the manga shows it to be, at least the author had the balls to show the reader "Hey, this country isn't perfect, and if a zombie invasion happens, we're [tornado fang]'d."
On another note, I think a new volume of Witch Hunter came out. Only manwha I'll ever enjoy.
