D.Gray-man (2006)
My rating: 5 of 5 stars
One of my favorite anime series, this follows the story of Allen Walker, exorcist, orphan and a rather haunted, driven individual with a unique past. Cursed with the ability to see the akuma possessing those in the living realm, he has a unique ability among exorcists that allows him to see beyond the outside and fight with a measure of surety and confidence that many others don't appreciate. It isn't until his cursed eye is injured that he realizes just how useful it is. Unfortunately the series was paused before it was completed as the manga is still in publication. Hopefully it will be picked up and completed again once the series has concluded.
