Berserk of Gluttony (Manga) Series by Isshiki Ichika, Daisuke Takino

Fate Graphite has never tasted true power. Born into a world with two kinds of people --those with superior skills and those without -- he's been shunned his entire life. Fate's skill is Gluttony, a curse that leaves him constantly hungry... until he awakens its terrible potential. When he kills someone, he can devour their skills and feed his insatiable appetite. How many lives will it take for Fate's Gluttony to finally be satisfied?

Having discovered the true power of his Gluttony skill, Fate Graphite has taken his first step toward becoming a warrior. Now he works as a servant in the home of Roxy Hart by day... and hunts monsters to satisfy his appetite by night. But the corpses left in his wake have sparked rumors of a lich on the loose. When Fate learns that his former tormentor, Hado Vlerick, seeks to slay his alter ego, this weakling-turned-warrior hatches a plan for revenge.

Fate's plan to support Roxy takes a sudden turn when enemies among her fellow holy knights send her on a mission that might as well be a death sentence. Hating his helplessness and hungry for revenge, Fate follows Roxy to the front lines to protect her... but not before resolving to devour those responsible!

Fate is headed to Galia, where mighty monsters and a reunion with Roxy await. He's joined by a mysterious woman who also possesses a deadly skill -- Wrath. For the first time in his life, Fate has an ally to fight beside him. But will this be enough to survive against his increasingly formidable foes? Or will Fate's ever-growing hunger finally consume him?

RAVENING FOR REVENGEFate has arrived in monster-infested Galia. But before he can continue to Babylon, the sentinel city where Lady Roxy is stationed, he must first fulfill his promise to Myne by putting down a powerful, ancient weapon. Then, just when he finally reaches his destination, Fate runs afoul another mysterious woman, Eris, who confronts him with a terrible truth!
