The first episode starts out slow but by the end has you believing this will be a thrilling anime. the characters are really cool and the concept is unique, but the rest of the anime doesn't deliver at all. Most of the episodes that follow after that seem to be more comic relief than anything else and the reasons for what the characters are told to do don't make any sense.
However the last 4 episodes are all pretty good and the ending is pretty emotional. All in all this was definitely worth watching and the character backgrounds were pretty interesting to learn but i felt like the anime itself didn't make good enough use of the great concept and character designs it started with.
