This is one of the few animes that I regard as a perfect work. Sadly, I almost missed it due to the first episode. I watched episode one and then got distracted because it seemed to be generic somehow but after some time I started watching from the second episode and everything changed. I honestly can't even begin to describe how awesome this series is, I can only say that you MUST NOT BE TURNED OFF BY THE FIRST EPISODE or you will be missing a legendary anime.
