akuma (d.gray-man)

Akuma are the monstrous creatures that exist in the D.Gray-Man series. They are created by the Millennium Earl, the main antagonist of the series, and serve and take orders from him and the Clan Of Noah. They are dangerous monsters who have no other purpose but to attack and kill humans and the more humans they kill the more powerful they become. It's the job of an Exorcist to find, fight and exorcise Akuma.
