Berserk of Gluttony

Fate Graphite has never experienced true power. Born with the magical skill called Gluttony, he has an inexhaustible appetite and has been constantly denigrated and scorned throughout his life.

One day, while working as a guard for an aristocratic family and fighting a thief, he discovers the true essence of Gluttony: when he kills someone, he consumes their skills, feeding his insatiable appetite. This is when Fate realizes his true potential.

How many lives will he gobble up to satisfy his hunger? And is the world ready for the terrifying warrior he is about to become?
