Looking for manhwa like Unholy Blood? Read Killer Peter first. It comes from the same two creators, and it's the closest thing to more of their work.
Unholy Blood (화이트 블러드, White Blood in Korean) is a short, finished story: Ha-Yan Park, a pure-blooded vampire who only wanted a normal life, teams up with police captain Eun-Tae Hwang to wipe out the half-bloods who turned Korea into a dangerous place ten years earlier. It ran from 2020 to 2021 and ended at 93 chapters.
That last part is a big reason fans still bring it up. "One of the reason why it's good and satisfying is because the author didn't stretch the story for more profit," one r/manhwa reader wrote. So this list leans on series that are finished, or that come from the same people.

Manhwa like Unholy Blood from the same creators
1. Killer Peter
Image: Killer Peter Korean volume 1 cover.
Killer Peter (킬러 배드로) is the direct follow-up for Unholy Blood readers, because WEBTOON credits it to the same pair: Kim Junghyun and Lim Lina. Peter spent his life as a legendary killer for the Glory Club, retired to run a quiet used bookstore, and then got ambushed by the organization he served. He survives with his body turned back to its teenage years and goes to settle the score.
No vampires, and the lead is a man, but the engine is familiar: a fighter far stronger than anyone expects, pointed at the people who wronged them. Readers made the link fast. One r/manhwa fan said to "go right now and read killer pietro made by the same girl who did unholy blood."
Pick it if: you liked Hayan out-classing everyone in the room. It's weekly on WEBTOON, Saturdays.

2. Dark Moon: The Blood Altar
Image: Dark Moon: The Blood Altar Korean volume 1 cover.
Dark Moon: The Blood Altar (DARK MOON: 달의 제단) is set in Riverfield, where the most popular boys at two rival schools are vampires and werewolves. A new student, Sooha, transfers in, both groups are drawn to her, and a string of horrible incidents starts to dig up the boys' forgotten pasts. HYBE is credited with the original plan, and it finished at 71 chapters.
It's more romance and mystery than revenge, so it's softer than Unholy Blood. Pick it if: you want vampires and a girl at the center of the story, and you're fine with a lighter tone. Our Dark Moon guide has the details.
3. Vampire Syndrome
Vampire Syndrome (뱀파이어 신드롬) is the darker vampire pick. A small group freed from death by a "vampire syndrome" has quietly taken control of the police, politics and the media; the few who know about them call them "The Afters." Taesu Dan, who lost everything because of them, puts together a team for revenge.
That's Unholy Blood's setup turned around: here the vampires own the police, and the hero is the one going after them from outside. It finished at 80 chapters and is complete on WEBTOON in English. Pick it if: you read Unholy Blood for the revenge plot.

4. Sweet Home

Sweet Home (스위트홈) has no vampires, but it's the pick here if you want a finished supernatural survival story. After a family tragedy, a reclusive high school student leaves home and lands in a world where monsters are trying to wipe out humanity, and he has to fight alongside a handful of reluctant heroes.
It finished at 141 chapters, and Netflix adapted it in three seasons between 2020 and 2024. Pick it if: you want more horror than romance. The Sweet Home reading guide explains how the webtoon and the show split.

5. Noblesse

Noblesse (노블레스) is the long, finished option. Rai wakes up from an 820-year sleep and starts a new life as a student at a high school founded by his loyal servant, Frankenstein, until attackers known as the Unions break the peace.
Rai is an ancient noble, not a vampire in the Unholy Blood sense, and his power is far above Hayan's. What carries over is the setup: an old, dangerous being who decides the humans around them are worth protecting. It finished in 2019 at 544 chapters. Pick it if: you want a lot more pages. Our Noblesse review gives it 7.5/10.
6. Eleceed
Image: Eleceed cover.
Eleceed (일렉시드) is the partnership pick. Jiwoo has a cat's lightning reflexes and uses them to do good in secret; Kayden is a secret agent on the run, stuck in the body of a fat old cat. They team up against the people who would let evil run the world, "if they can stand each other long enough."
It's much funnier than Unholy Blood and not finished: it updates weekly on WEBTOON, Tuesdays. Pick it if: Hayan and Eun-Tae's partnership was the part that kept you reading. Eleceed review: 8.6/10.
7. Bastard
Image: Bastard Korean volume 1 cover.
Bastard (후레자식) has no supernatural element at all. Seon Jin is a sickly, disabled boy the bullies prey on, and he keeps a very dark secret: there's a serial killer in his house, and it's his father. It's by Carnby Kim and Hwang Young-chan, the team behind Sweet Home, and it finished at 94 chapters.
Pick it if: you want a short, finished thriller where the threat lives under the same roof. The Bastard reading guide has the full run.
Our Take
Start with Killer Peter: same creators, same appetite for a lead who outclasses everyone. If you came for the vampires, Vampire Syndrome is the better match than Dark Moon, which trades revenge for romance. Sweet Home and Bastard are the safest finished reads on the list, and both come from one team. Skip Noblesse unless you're ready for more than five times Unholy Blood's length.
Unholy Blood's fans are split on its overpowered lead. One r/webtoons reader put it this way: "i'm glad this webtoon knew when to end because powerscaling when your main character is literally the strongest vampire alive is a nightmare." If that was your problem too, try Bastard: its hero is a sickly kid the bullies pick on, living with a killer.
How we checked this: on October 19, 2026 we read the English WEBTOON pages for Unholy Blood and all seven picks, pulled AniList data for all eight series, checked Wikipedia for the Sweet Home adaptation, and read the r/manhwa and r/webtoons threads linked above.
