For those who know nothing about anime it should better be on your list of firsts.Except in the last 2 episodes and some scene in third last episode and hardly in some scenes of other previous ones the anime story follows the main story.but the real -2 on the anime is that it is hastily ended on following the manga it ends in a total wreck.besides that the main characters are excellent ; well connected to the story , the story-line is strong and the animation is good.what makes this anime good are the characters of the story line,they are complex as well as fairly simple to understand and feel for.the story line since is a monthly shonen so,doesn't suffer much stretching as for most of the weekly ones and has a sense of flow to it.It has everything you'd expect from a sword,dark fantasy tragedy anime and much more.

so if you are anime fan and like to watch it i think you should skip last two episodes and continue the story-line with manga.
