Story is decent..if you like plots with strong FL nad a lot of grey characters with slow to medium rate of unfolding of plots then you will like it. Personally, i dropped after reading through 142 chapters .(manga version, if their is a light novel i don't know upto which chapter) it became very frustrating as the story was not leading anywhere..i could not see an ending to the plot ....just sort of bored it after that. Rest it has a great art and story.... definitely great...i don't know if it is worth the hype .
