Hiromu Arakawa Fullmetal Alchemist^Fullmetal Alchemist, Vol. 6

In an alchemical ritual gone wrong, Edward Elric lost his arm and his leg, and his brother Alphonse became nothing but a soul in a suit of armor. Equipped with mechanical “auto-mail” limbs, Edward becomes a state alchemist, seeking the one thing that can restore his and his brother’s bodies…the legendary Philosopher’s Stone.

The origin of the Elric Brothers! Once, Edward and Alphonse Elric were willing to do anything to become alchemists. But when they tried to use their newfound skills to resurrect their dead mother, they broke a taboo and encountered something more terrifying than death itself. Now, hardened by years of military training, Edward and Alphonse have returned to the woman who first taught them alchemy…but can she help them, or even forgive them?
