The studio who did kyoto animation have had some of the biggest shows down the years. Shows like: full metal panic fumoffu, air, the melancholy of haruhi suzumiya, kanon, lucky star, clannad, the big daddy itself K-ON and most recently free.
However this show is very much different to all the most populars ones they have done and to be honest it does not really intrest me to much. You can see that the animation is unbeliveable and it is for most of their shows. However they never do action shows that often and the only popular one they did was the second season of full metal panic which was meh and i cant really me enjoying it
