D.Gray-man follows the Black Order, an organization of Exorcists fighting Akuma—soulless weapons created from human grief—while trying to protect the world from the Millennium Earl and the Noah Family. At the center of the conflict is Allen Walker, a young Exorcist with a cursed left eye and arm who can see the suffering inside the Akuma he destroys. As he travels with allies such as Yuu Kanda and other members of the Order, Allen is constantly pulled between duty, hidden histories, and the growing shadow of the mysterious 14th Noah.
Across the franchise, the Black Order faces relentless attacks from the Noah Family, the Central Agency tightens its control, and General Cross Marian’s secrets continue to shape Allen’s path. In HALLOW, the Order relocates after recent Akuma attacks, Allen is summoned by the Central Agency and has his arm forcefully sealed, and a series of unsettling events—including a phantom thief incident, the arrival of a mysterious group of Exorcists, a devastating loss, and an all-out battle against the Noah Family—push the cast toward revelations surrounding the enigmatic 14th Noah.
