i've seen the first 5 episodes and i thought it was better than what everyone said it would be.
Being given a second chance to fight demons. what a cool idea. the characters are funny, specially kei. Most people say they messed the ending up but i find it hard to believe. i was surprised by its art. the art is probabley the best ive seen in manga. the only let down is the amount of nudity in it and sexual behaviour. But except that it is one hell of a show, and i recomend you watch it.
