Man, the moment you see Guts you know it's going to be bad news. I loved that contrast with the bright, fairy-tale environment with the heavily shadowed realism. You instantly get that ominous feeling and it perfectly encapsulates the darkness that Guts has wrapped himself in since he began his quest for revenge. This development certainly isn't going to help the poor guy...
