Fullmetal Alchemist, Tome 1 by Hiromu Arakawa

Two brothers, Edward and Alphonse Elric, grapple with the catastrophic consequences of a forbidden attempt to bring their mother back to life—Alphonse loses his entire body and Edward loses limbs, binding his brother’s soul to a suit of armor and receiving automail prosthetics of his own—and the volume follows their decision to join the military as a means to seek the Philosopher’s Stone that might restore them, introducing their childhood friend who maintains his prosthetics and setting up themes of sacrifice, responsibility, and the moral costs of using alchemy.
