Boushoku no Berserk

Boushoku no Berserk: Fate Graphite is one of the forsaken. Cursed with the skill "Gluttony," he is ever starving, never sated... until the day he kills a dying thief and devours the man's strength—and his soul. The true hunger of Fate's Gluttony has awakened, and if he can learn to control his power, he will at last be the master of his own destiny.
