Berserk of Gluttony

Fate Graphite lives in a world where magical abilities determine a person's worth. His own skill, Gluttony, is seen as a curse-an endless hunger that brings him nothing but scorn. But when he accidentally kills a thief, he discovers the horrifying truth behind his power: he can steal the skills of those he consumes. Now he must grapple with this brutal ability and decide whether to wield it for good or let it consume him.
