Disaster-Class Hero Reading Guide: Saints and Revenge

This Disaster-Class Hero reading guide covers where to start, whether to read the manhwa or the novel, and how the twelve-saints revenge structure shapes the series. The Return of the Disaster-Class Hero is a straightforward read to get into, as long as you understand the one detail the whole revenge plot hangs on: nobody chose Lee Geon, and that is exactly why they betrayed him.

TL;DR: Start at Episode 1 on WEBTOON and read in order. The series is linear, structured around Lee Geon's revenge on the twelve saints who betrayed and sealed him for twenty years. Read the manhwa first for REDICE Studio's art; switch to Sanjijiksong's web novel only if you run out of episodes. 170+ chapters so far, ongoing. The detail that unlocks the whole story: Geon became the strongest without any god choosing him, and the betrayal is the system protecting itself.

Disaster-Class Hero reading guide: where to start

Start at Episode 1 on WEBTOON, and read straight through in order. There is no complicated reading sequence: no side stories to track first, no companion series required, no seasonal split that strands the story.

The premise is established immediately. The calamities, monsters that came to wipe out humanity, were fought by twelve saints, each granted divine power by a zodiac god. Lee Geon was the thirteenth, the one no god chose. He became stronger than all twelve anyway, which made him a hero and a threat, so the twelve betrayed him and sealed him in the Tower of Demons for twenty years. The series opens as he brawls his way out and starts working through a list of twelve names.

Because the story is built on that revenge list, the reading order is simply the order Geon confronts his targets. Start at the beginning and follow the hunt.

It helps to hold the world's basic shape in your head as you read. The calamities are the existential threat, monsters that came to end humanity, and the zodiac gods are the powers that responded by choosing twelve champions to fight them. That selection system is the spine of the whole setting: power in this world is supposed to flow down from the gods to their chosen, and the hierarchy assumes that the strongest people are the ones the gods picked. Geon breaks that assumption simply by existing, which is why his story is as much about the legitimacy of power as it is about revenge. Keeping the calamity threat and the god-selection system straight makes the early chapters read faster, because almost every faction and motive traces back to one or the other.

How the twelve-saints structure reads

The revenge-on-twelve structure is the most useful thing to understand about reading this series, because it shapes the rhythm. Each saint is a distinct target with a separate arc: what they became in the twenty years Geon was sealed, how their corner of the world works, and why they personally turned on him. The series moves through them, and each confrontation is its own mini-story within the larger hunt.

This makes the series readable in chunks. A saint's arc is a natural stopping point. You can read through one target's confrontation, set it down, and pick up at the next without losing the thread. For a 170-plus chapter series, that structure keeps it from ever demanding you hold a dozen open plot threads at once.

The trade-off is that the saints are not all developed equally. The strongest stretches are the ones where a saint is more than an obstacle, where their betrayal had a real reason that complicates the simple revenge framing. Some targets get rich, layered arcs; others get a shorter confrontation. The quality fluctuates with how interesting each saint is, so the back half of the list can feel uneven compared to the strongest early targets.

The reading order is the revenge order: Geon works through the twelve saints one by one, each confrontation its own arc within the larger hunt.

Step-by-step: how to read Return of the Disaster-Class Hero

1. Open WEBTOON or Tappytoon and search "The Return of the Disaster-Class Hero." Start at Episode 1.
2. Read the opening arc for the setup. The first stretch establishes the calamities, the twelve saints, the betrayal, and Geon's escape. This is the framework every later confrontation assumes.
3. Hold onto the "no god chose him" detail. It is the thematic key: Geon's strength is self-made in a world that only respects the divinely chosen, which is why the twelve had to remove him. Reading the revenge with that in mind makes it land harder.
4. Read saint by saint. Use each target's confrontation as a natural break point if you are not binging.
5. When you catch up to the manhwa, switch to the novel if you want more. Sanjijiksong's web novel runs ahead of the webtoon's current position.

Manhwa vs. web novel: which to read

The manhwa is the better entry point. REDICE Studio's art, by Beom-Geun Lee, gives the calamity designs and saint duels real menace and keeps the action legible even when the power levels get absurd. For a series where the protagonist can level a city block, that visual clarity matters, and you lose it in prose.

The web novel by Sanjijiksong is the source material and runs ahead of the manhwa. It is the natural continuation once you finish the available webtoon episodes. The prose does not have the art's impact for the big set-piece fights, but if the revenge has you hooked, the novel is where the rest of the hunt continues.

The recommendation: manhwa first, novel as a follow-up. Do not start with the novel unless you specifically prefer prose, because the manhwa's art is a major part of the appeal.

Reading tips for Return of the Disaster-Class Hero

The single most useful thing to know going in: this is a spectacle-forward series, not a suspense one. Geon is already the strongest being in almost every room, so individual fights rarely leave the outcome in doubt. The tension is in the revenge and the mystery of the betrayal, not in whether he wins. Read it for the satisfaction of the hunt and the unraveling of why the twelve turned on him, and it delivers.

Pay attention to each saint's backstory rather than skimming to the fight. The series is at its best when a target's betrayal has a reason that complicates the simple revenge, and those reasons are where the writing earns its weight. The fights are the payoff; the setup is where the story lives.

If you came from Solo Leveling or other dungeon-hunter fantasy, note that this is a returner-revenge story rather than a climb. Geon does not grow into his power across the series, he starts with it, and the arc is about settling debts. Adjust your expectations accordingly and the pacing makes sense.

Coming from Solo Leveling sets the wrong expectation: Disaster-Class Hero is a returner-revenge story, not a weak-to-strong climb.

For readers who find the saints uneven: the strongest arcs are worth the weaker ones. When the series lands on a well-developed target, it is genuinely good, and that ratio stays favorable enough to keep going.

A note on how to pace it. Because each saint is a self-contained confrontation, the series is forgiving of stop-start reading in a way a single-threaded story is not. You can put it down after one target and come back weeks later without losing the plot, since the next saint resets the local stakes. That makes it a good choice for a casual, between-other-series read rather than a single marathon. The one thread you do need to keep is the overarching question of why the twelve betrayed Geon, because the answer deepens as the hunt goes on, and the later confrontations land harder if you have been paying attention to what each earlier saint revealed about the betrayal. Read the fights however you like; just keep the why in mind.

If you finish the manhwa and the revenge has you invested, the web novel is the immediate continuation. It is worth setting expectations: fan-translated prose does not carry the art's spectacle, so the experience shifts from watching the fights to reading them. For a series this spectacle-forward, that is a real change in register, but the plot and the saint confrontations are all there, further ahead than the manhwa has reached.
