Is Gosu Worth Reading? Review & Where to Read

Overview

Gosu (also known as Gosu: The Master) is a completed Korean manhwa written by Giun Ryu with art by Mun Jeong Hoo, published on WEBTOON, and a sequel to the earlier manhwa Yongbi the Invincible. When his master is betrayed and killed, Gang Yong trains in seclusion and sets out to hunt down the traitors responsible, only to arrive in town and discover they're already dead. Working undercover as a chubby dumpling delivery boy, he has to untangle who actually got to them first while carrying his master's supreme martial arts techniques into the murim underworld.

What it does well

The opening twist, that Gang Yong's targets are already dead when he arrives, does a lot of work to set Gosu apart from a standard revenge story. Instead of a straightforward hunt-and-kill structure, the manhwa becomes a mystery about who else wanted these men dead and why, which gives Gang Yong's journey more to chew on than simple retribution.

The series also has a distinctive tonal range. Gang Yong's cover as a bumbling dumpling delivery boy generates real comedy, but it sits right alongside genuinely brutal, high-stakes murim combat once the fighting starts. That contrast keeps a very long revenge story from becoming exhausting across its 200-plus chapters.

As a sequel to Yongbi the Invincible, Gosu also inherits a world with real history behind it: established factions, old grudges, a sense of a murim underworld that existed before the story started, even though newcomers can follow Gosu perfectly well without having read the original first.

Where it falls short

The comedic framing in the early chapters, especially Gang Yong's delivery-boy disguise, can undersell how dark and violent the story becomes later on, which might catch readers off guard if they came in expecting a lighter tone throughout.

At 233 chapters, the mystery behind who killed Gang Yong's targets takes real time to unpack, and the expanding cast and side arcs can slow the pacing for readers who want a tighter, more direct revenge plot.

Verdict

Gosu takes a familiar murim revenge premise and immediately complicates it with a mystery that carries the story across a massive, complete run. It's a rewarding, tonally distinctive read for genre fans willing to commit to its length, with an anime adaptation reportedly on the way.
