The drawing style of humans in the series is a bit different compared to mainstream shounen (or any other pretty much) shows. It's not shining and flawless, but rather cruel and rough. However, in the end it fits perfectly the merciless story, and the fact those rough looking people must all the time do very tough choices.Originally Posted by xDarkMaster
To be honest, if this show had had clean and bright and innocent graphics like Naruto, do you think the story would have worked nearly as well as it does now? Well, after just one episode it might be impossible to see this, but later on.
