Is Berserk of Gluttony Worth Reading? Review & Where to Read

Overview

Fate Graphite has the Gluttony skill, which everyone in his party treats as a joke: instead of gaining experience and leveling up the normal way, it lets him devour and absorb the abilities of whatever he eats. After his party dumps him for looking useless, Fate ends up using that exact skill to become genuinely terrifying — not by grinding stats, but by literally consuming the powers of the monsters and people who underestimated him.

What it does well

The hook is the thing that sets this apart from the dozens of other "betrayed hero gets stronger" isekai on the shelf right now. Gluttony isn't just a reskinned power-up button — it's a mechanic the story actually uses. Fights become as much about what Fate can eat and absorb as about brute force, and that gives Daisuke Takino's art something concrete to draw: skill effects, monster anatomy, and absorption sequences that make each encounter look and feel a little different from the last. The art is a real asset here. Fight choreography reads clearly even in busy panels, and the character and creature designs have enough bite to make the power-fantasy moments land as satisfying rather than just loud.

The pacing in the opening volumes also works in the story's favor. A lot of isekai in this exact revenge-power-fantasy lane spend a long time wallowing in the hero's humiliation before letting them turn the tables; this one gets through the setup fast and lets Fate start winning early, which keeps the momentum up instead of testing your patience. Once the party dynamic with Roxy and Mine settles in, the group fights add some actual coordination and variety rather than just watching Fate solo every threat, which helps keep the later volumes from feeling repetitive.

Where it falls short

Fate himself doesn't get much of an arc beyond "quietly overpowered guy proves everyone wrong" — he's a perfectly serviceable lead for this kind of story, but if you've read even a handful of isekai, there's nothing about his characterization that's going to surprise you. The opening act leans hard on the betrayal-and-humiliation trope that's become genre shorthand at this point, and the manga doesn't do much to make that stretch feel distinct before the power fantasy kicks in and the story gets more fun. The world outside the guild and status systems also stays pretty thin — it's there to give Fate things to fight and consume, not to build a setting with much texture of its own.

Verdict

Berserk of Gluttony isn't trying to subvert the revenge-isekai formula, but the Gluttony skill gives it a genuinely good mechanical hook, and Takino's art sells the fights hard enough to carry you past the generic setup. If you want an isekai power fantasy with a clever gimmick and don't need deep characters to enjoy the ride, this delivers. If you're burned out on the betrayed-hero template specifically, this one won't change your mind about the genre.
