In the late 1800s, Allen Walker becomes a member of a group called Exorcists, whose mission is to eliminate Akuma—mechanical weapons created by the Millennium Earl using the souls of the deceased. Allen possesses a cursed eye and a weaponized arm known as Innocence, a power granted to him as an apostle of God. He and his fellow Exorcists work to prevent the Millennium Earl’s plan, which threatens to destroy the world and everything in it.
