D-Grayman was originally a Japanese manga series written and illustrated by Katsura Hoshino that was later adapted into a 103 episode anime series. The original manga was published by Shueshia and was initially released on the 31st of May of 2004 and is still on-going. The anime on the other hand was initially televised on the 3rd of October of 2006 with its last episode airing on the 30th of September 2008. The anime was directed by Osamu Nabeshima and the animation studio was TMS Entertainment. D-Grayman is somewhat similar to the manga and anime Claymore in the sense that both have a dark atmosphere and seems to emulate a battle manga or anime feel usually found in mainstream anime like Naruto, Bleach and One Piece.
D-Grayman’s manga series became one of the best sellers for Shueisha and in fact, during its second release week, the 15th volume of the manga ranked second throughout Japan. The anime was also well-received.
"D-Grayman’s story revolves around the battle of the forces of good and evil in the near end of the 19th century. A being who calls himself the “Millenium Earl” (千年伯爵 – Sennen Hakushaku) and his allies, the Noah family, plots to annihilate all of humanity. The earl tricks bereft people into calling back the souls of their beloved departed and then turns them into Akuma (which means demon)to do the earl’s evil bidding while disguised as humans.
The Black Order; an organization consisting of Exorcists, whose sole purpose is to stop the earl’s evil plans takes in the 15-year old young boy named Allen Walker and inducts him as an Exorcist. Each Exorcist is equipped with Anti-Akuma Weapons (対アクマ武器- Tai Akuma Buki which literally means “Versus Akuma Weapon”) that are made out of innocence; a unique material that is capable of destroying Akuma while also being able to release the trapped souls within the Akuma.
Allen Walker on the other hand, is unique among his fellow Exorcists because his Anti-Akuma Weapon is merged to him in the form of his left arm, transforming into a monstrous clawed hand. In addition, he also has a cursed left eye which allows him to see the souls of Akuma which helps him in identifying Akuma who disguise themselves as humans. Together, with his fellow exorcists, he fights against the Millenium Earl and the Noah Family to put a stop to their evil machinations."
