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 mans strength—and his soul. The true hunger of Fates Gluttony has awakened, and if he can learn to control his power, he will at last be the master of his own destiny.
