I started by reading the manga about a year ago and have followed it since. However the anime was not nearly as good as the manga. Season 1 was okay because everyone was stupid noobs. The second season was a letdown. Kurono was a winy bitch too obsessed with morals which ruin the last 3 episodes. The manga allows the characters to get stronger while the anime keeps the characters weak and timid. The only redeeming aspect of the end is that it could allow for additional seasons to follow up and continue the series. 8/10 :( disappointing.
