~D.Gray-Man~

Set during the end of a nineteenth century on a fictional Earth, D.Gray-man mostly centers around 15-year-old Allen Walker, who is gifted with the ability to control a weaponized form of a divine substance from ages past, called Innocence, and becomes an Exorcist of the Black Order. This secretive organization aims to stop the plan set in motion by the Millennium Earl to destroy all life on Earth, thus 'cleansing' it. But the Earl has raised an army of Akuma, created by taking advantage of grief over a loved one's death, and summoned the direct descendants of Noah himself, the 13-strong Noah family, to aid him in his second attempt. Because of the Akuma's ability to wear a human's skin, they are nearly undetectable by any human. Allen proves to be a powerful asset as his 'cursed' left eye is able to detect the Akuma. But soon, this battle nearly turns into a race to collect the 109 Innocence fragments, scattered since the Great Flood of Noah, as the search to find the most powerful Innocence, the 'Great Heart', ensues.
