Fullmetal Alchemist: Fullmetal Edition, Vol. 9

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. Monster, human, friend and foe—definitions blur when Ed is trapped in the belly of the beast with his enemies.
