D.Gray-man

Step into a gothic alternate 19th century where humanity faces an existential threat from the Akuma, monstrous weapons born from the grief of the living and animated by the malevolent Millennium Earl. Only the Black Order, an organization of exorcists, stands as a bulwark against this encroaching darkness. Their power stems from "Innocence," a divine substance scattered across the globe, capable of destroying these demonic entities. Join Allen Walker, a young exorcist with a cursed eye that can perceive the souls bound within the Akuma, as he embarks on a perilous journey. He and his comrades navigate a world teetering on the brink, battling not just the Earl's forces but also the moral ambiguities of their fight, all while searching for the remnants of Innocence to save mankind.
