I have never seen an anime follow the manga quite so closely before. There are very minor differences, the biggest one being how Gareki leaves at the very end of the show, but other than that it is almost perfect. The anime really left on a cliffhanger and I would highly recommend reading on from where the anime left off in the manga. The show is unlike any style I've seen before and it's communicated very well. The colours are sparkly and vibrant and very pleasing to look at. The english dub isn't hard to sit through at all, in fact it's one of thebetter dubs in anime history.
