I've just watched the first episode, this anime looks pretty promising to me, hopefully they can turn this into another Fate/Stay Night...that will be cool, anyway, just for opinion's sake, which sub group is better? Mishicorp's version or Kyuuketsuki's version? In terms of video quality?

I thought for subbing wise, they are pretty much the same, as i know some jap, i think they translated rather accurately. And i can confirm that it should be Shard Caster instead of Shadow Caster...

I'm pretty curious as to why there is this annoying 30-something number on the top left-hand corner of Kyuuketsuki's version for the first few episodes (browsed through the 1st few secs of other epis as i thought there was an error)
