Berserk of Gluttony

A cursed skill devours souls to fuel a hero's rise.

Fate Graphite was born with Gluttony — a skill that brands him a pariah in a world where your birthright ability dictates your worth. Condemned to eternal hunger and treated as refuse by the holy knights who claim to protect society, he scrapes by as a gatekeeper until a dying thief crosses his path. Killing the man triggers Gluttony's true nature: it devours not just food, but souls, stats, and skills, rewriting Fate's destiny in a single night. Recruited by Roxy Hart, the lone knight who sees his humanity, and partnered with Greed, a sentient sword with a wicked sense of humor, Fate walks a razor's edge. By day, he's a model employee; by night, he hunts monsters to feed the insatiable void inside him, knowing that if he starves, the berserk state will consume his mind. A.C.G.T. leans into the power-fantasy spectacle — flashy skill acquisitions, escalating threats, a protagonist who grows stronger by consuming his enemies — but the series works best when it lingers on the grotesque intimacy of Gluttony: the moral rot of gaining strength through slaughter, the isolation of a power that demands you become a monster to stay human. It's a familiar isekai-adjacent climb, elevated by a premise that makes every level-up feel like a small damnation.

A dark fantasy where a mistreated gatekeeper gains power by consuming the souls of those he kills, forcing him to hunt monsters nightly to stave off a berserk state. Expect moderate fantasy violence with body-horror undertones, themes of institutional cruelty, and a protagonist walking a morally gray line to survive.
