About the Berserk of Gluttony Manga Volume 2

Fate Graphite has never tasted real power. Born with the magical skill Gluttony, he has been shunned and looked down upon his entire life, and constantly hungers in a way that can't be satiated. One day, while working as a gatekeeper for a noble family and fighting a trespassing thief, he discovers Gluttony's true power: when he kills someone, he devours their skills and feeds his gnawing hunger at last. In that grisly realization, Fate is awakened to his true potential. How many lives will he feed on to satisfy this hunger, and is the world ready for the terrifying warrior he'll become?
