Hagane no Renkinjutsushi

Description:

Alchemy tore the Elric brothers’ bodies apart. Can their bond make them whole again?
In this world, alchemists are those who study and perform the art of alchemical transmutation—the science of manipulating and transforming matter. They are bounded by the Law of Equivalent Exchange: in order to gain something, one must sacrifice something of equal value.
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.
