Last 10 episodes is where he changed, I think but yeah what he said.
Anyways, D.Grayman is an awesome anime but it may be a little creepy. It freaked me out a bit the first time I watched it. Those monsters were just so ugly lolz
Anyways, the anime is really awesome, it's action packed. Also, there are funny parts in it which makes the anime balanced so not just action is there. There is action, comedy, a little bit of romance, and basically it just rocks.
I love the character design for this anime because Allen just looks like some super cool guy with powers. It kind of reminds me of Edward Elric from Full Metal Alchemist espectally the arm thing, because Edward's arm was mechanical and Allen Walker's hand is also mechanical in some sort.
By the way, Allen Walker is the main character of the anime; he is the one with the white hair
.
Allen Walker also meets up with some awesome people and becomes friends with them. This anime just really interests me due to the action and just the story line is awesome. This is like a Bleach, Naruto, and Full Metal Alchemist combined all in one.
I really hope this post has made you decide to watch D.Gray-man
