Manhwa Like I Killed the Main Player: 6 Similar Picks

Manhwa like I Killed the Main Player, organized by which part of the premise you actually want more of.

Not every regression manhwa does all three. The picks below sort by which piece you're chasing.

Manhwa like I Killed the Main Player: quick answer

What makes I Killed the Main Player specific

Corin isn't the protagonist by any conventional measure, which is exactly the point. If you're after a manhwa where the side character is the real protagonist, this is about as literal as the trope gets: he supports the actual main player, Sihu, until he learns Sihu has been murdering other NPCs for their items. When the run collapses, Corin gets thrown three years into the past and decides to kill Sihu and take his role instead of just trying to survive the loop again.

Three structural choices make that premise work, and they're the three things worth chasing in a recommendation list. First, Corin is informationally advantaged but not physically stronger than his target, so the story has to be about strategy rather than escalating stats. Second, it's a single jump: there's no resetting if a plan goes wrong, which raises the stakes of every decision compared to a series where the lead can just try again. Third, the world still treats Sihu as the hero throughout, so Corin is acting against the person everyone else believes in, not a clearly marked villain.

For knowledge that beats raw power

SSS-Class Suicide Hunter

SSS-Class Suicide Hunter, story by Neida, based on the novel by No-A Sin, art by Bill K.

Kim Gong-ja's ability requires him to be killed by an opponent to copy their skill and reset back to just before that death. The reset isn't free: it's purchased with his own death every single time, which is the same kind of built-in cost that makes Corin's information advantage feel earned rather than handed to him. The series doesn't treat the copy mechanic as a shortcut around difficulty. Every fight is a calculation about which death is worth affording.

That calculation is the whole appeal. Gong-ja is rarely the strongest person in a room. He's the person who has died to the room's strongest person the most times, which is a very different kind of advantage than raw power, and it's the closest thing on this list to Corin's specific situation: out-thinking someone who could beat him straight up.

8.5/10 on our SSS-Class Suicide Hunter review. Season 4 recently wrapped and the series is on a scheduled hiatus, so it's a good point to catch up. Available on Tapas.

Omniscient Reader's Viewpoint

Omniscient Reader's Viewpoint, story by Sing-Shong, art by Sleepy-C.

Dokja is the only person who has read the web novel that the apocalypse is now playing out as real events. He's not a system-granted hero and he's not physically exceptional. His advantage is that he knows how the story ends, who the important characters are, and which choices are traps, which is the same outsider-with-complete-knowledge position Corin occupies relative to the game world he understands better than anyone actually living in it.

The scale is different: Omniscient Reader's Viewpoint runs on an ensemble cast and a much larger canvas than I Killed the Main Player's more contained cat-and-mouse structure. But the core mechanic, knowing the plot and having to act within a world that doesn't know you know it, is the same engine.

9.2/10 on our Omniscient Reader's Viewpoint review, the highest-rated pick on this list. Season 1 is complete at 311 chapters. WEBTOON and Naver Webtoon.

For the not-the-chosen-one framing

Lout of Count's Family

Lout of Count's Family, story by Ryeo-Han Yu (original novel), art by PAN4.

Kim Rok-Soo possesses Cale Henituse, a minor character whose only ambition in the story he's read is to avoid dying an early, unimportant death. He has no interest in becoming the hero. He actively tries to stay out of the plot, and the joke of the series is that his survival instincts keep dragging him back into the exact events he's trying to dodge.

The overlap with I Killed the Main Player is structural: both protagonists start from a position the genre normally treats as disposable, and both have to use knowledge of the "real" story to navigate around people who are positioned as more important than they are. Rok-Soo's goal is comedic self-preservation rather than Corin's more deliberate role-usurping, so the tone lands lighter, but the underlying inversion is the same.

7.5/10 on our Lout of Count's Family review. Ongoing at 176+ chapters. Available on Tappytoon, Tapas, KakaoPage, and Manta.

The Extra's Academy Survival Guide

The Extra's Academy Survival Guide, story and art by Korita.

Ed Rothtaylor knows he's a background character in a story where four women are destined to fall for the actual protagonist. His entire strategy is staying invisible enough that the plot never notices him, which is nearly the opposite instinct from Corin's decision to actively hunt Sihu down, but the premise starts from the same place: a character who's supposed to be scenery, armed with knowledge the story's real cast doesn't have.

Where I Killed the Main Player plays that setup for tension and strategy, The Extra's Academy Survival Guide plays it for comedy. If the appeal of Corin's situation is watching a background character outmaneuver people who don't know he's paying attention, this is the same idea with the stakes turned down and the jokes turned up.

8.2/10 on our The Extra's Academy Survival Guide review. Complete at 108 episodes. Free on WEBTOON.

For a single jump, not a repeating loop

A Returner's Magic Should Be Special

A Returner's Magic Should Be Special, story by Usonan, art by Wookjakga.

Desir Arman returns from a catastrophic future with the knowledge of who becomes powerful and why, and like Corin, he doesn't get a second attempt if his plan doesn't work. There's no loop to fall back on. Every choice he makes in the present has to account for the fact that this is the only run he gets.

The structural similarity to I Killed the Main Player is exact: both series treat the single-jump format as raising the stakes rather than removing them, which is a deliberate departure from the more common resettable-loop regression story where failure just means trying again.

7.0/10 on our A Returner's Magic Should Be Special review. Completed at 268 chapters. Tappytoon and Yen Press for the English print release.

Return of the Blossoming Blade

Return of the Blossoming Blade, story by Biga, art by Studio Lico.

Chun Myung watched his sect get destroyed once and regresses to before it happened, carrying knowledge of who will betray them and which alliances will actually hold. Like Corin, and like Desir above, he doesn't get to try again if a specific plan fails: the knowledge only extends as far as the first run went, and every decision past that point is genuinely uncertain.

The murim setting is a different genre wrapper than I Killed the Main Player's game-world framing, but the mechanic underneath is close: a protagonist using foreknowledge as a strategic resource rather than a guaranteed outcome.

9.1/10 on our Return of the Blossoming Blade review. Ongoing at 176+ chapters. Free on WEBTOON.

Manhwa like I Killed the Main Player: which pick actually matches what you want

If the appeal was watching Corin out-think someone stronger than him, start with SSS-Class Suicide Hunter. If it was the specific feeling of knowing a story better than the people living in it, Omniscient Reader's Viewpoint is the deeper version of that idea. If you want a background character who genuinely isn't the chosen one, Lout of Count's Family and The Extra's Academy Survival Guide both commit to that harder than most of the genre. If the single-jump stakes were the draw, A Returner's Magic Should Be Special and Return of the Blossoming Blade both keep that same no-do-overs pressure.

None of these six repeat I Killed the Main Player's exact combination of all three elements at once, which is part of why it's worth reading on its own terms rather than treating any single pick here as a direct substitute.

Frequently Asked Questions

What manhwa is most similar to I Killed the Main Player?

SSS-Class Suicide Hunter is the closest structural match: knowledge is the actual weapon, not a supplement to power, and the protagonist has to out-think opponents who are stronger than him on paper. Omniscient Reader's Viewpoint is the closest match for the outsider-with-complete-knowledge angle specifically.

Is there manhwa like I Killed the Main Player where the protagonist isn't the chosen one?

Lout of Count's Family (also known as Trash of the Count's Family) and The Extra's Academy Survival Guide both put a background character at the center instead of the story's intended hero. Neither protagonist is positioned as special by the world around them, which is the same inversion I Killed the Main Player runs.

What manhwa has a single regression jump instead of a repeating loop?

A Returner's Magic Should Be Special and Return of the Blossoming Blade both use one return trip rather than a resettable loop, the same structure as I Killed the Main Player's three-year jump. Neither protagonist gets to try again if a plan fails.

Are these picks completed or ongoing?

Omniscient Reader's Viewpoint (Season 1), The Extra's Academy Survival Guide, and A Returner's Magic Should Be Special are all completed or have a completed first arc. SSS-Class Suicide Hunter is on a season break after completing Season 4. Lout of Count's Family and Return of the Blossoming Blade are both ongoing.

What makes I Killed the Main Player different from standard regression manhwa?

The protagonist, Corin, isn't the chosen one who regresses to get stronger. He's a minor NPC who regresses specifically to stop the actual main player, Sihu, who turns out to be a murderer. Most regression manhwa put the hero back in his own timeline; this one puts a side character in someone else's.
