If you’ve spent any time on Netflix recently, you’ve probably seen the neon-soaked, high-octane world of KPop Demon Hunters. It’s basically everywhere. The movie somehow managed to mix high-fashion idol aesthetics with brutal supernatural battles, and honestly, it works way better than it should. But while everyone is obsessed with the girl group HUNTR/X, there is one character that has the internet in a total chokehold: Jinu.
He’s the leader of the Saja Boys, the rival boy band that—spoiler alert—turns out to be a pack of literal demons. But he’s not just some generic villain. Jinu is complicated, tragic, and let’s be real, his character design is top-tier. Naturally, everyone is asking the same thing: who played Jinu in Kpop Demon Hunters?

The Man Behind the Voice: Ahn Hyo-seop
The speaking voice for Jinu is none other than Ahn Hyo-seop. If you’re a K-drama fan, you definitely know him. He’s the lead from Business Proposal and Dr. Romantic. This was actually his first-ever English-speaking voice acting role, which is wild because he absolutely nailed the brooding, charismatic energy Jinu needed.
Ahn Hyo-seop was born in Seoul but moved to Toronto when he was six, so his English is perfectly fluent. That’s why his performance feels so natural. In interviews, he’s mentioned that he loved playing Jinu because the character has his own "atmosphere and speed." Jinu isn’t just a bad guy; he’s a guy who made a desperate deal 400 years ago to save his family and has been living with the guilt ever since.
Why the Singing Voice is Different
Now, here is where it gets interesting. While Ahn Hyo-seop handles the dialogue, he doesn't actually do the singing. In the world of high-budget animation, this "split" is pretty common. The singing voice for Jinu is provided by Andrew Choi.
Andrew Choi is a heavy hitter in the K-pop industry. He took third place in K-pop Star Season 2 and has written songs for legends like SHINee and EXO. When Jinu hits those high notes in the movie, that’s all Andrew. The blend between Ahn’s speaking voice and Andrew’s vocals is so seamless that most people don't even realize they're listening to two different performers.
Is Jinu Really a Villain?
Most people go into KPop Demon Hunters expecting a simple "good vs. evil" story. HUNTR/X are the heroes, and the Saja Boys are the villains. Simple, right? Not really.
Jinu is what you’d call a "human-turned-demon." He started as a busker in the Joseon dynasty, trying to feed his mother and sister. The demon king Gwi-ma (voiced by the legendary Lee Byung-hun) manipulated him at his lowest point. He told Jinu he wasn't good enough to save his family but promised to "help" him.
The tragedy of Jinu is that he spent centuries believing he abandoned his family for a life of luxury. In reality, he was a victim of psychological grooming. He’s a survivor who has been conditioned to think he’s evil. This complexity is why the fandom is so protective of him. He doesn't want to be a monster; he just thinks he doesn't have a choice.

The Connection to Real K-Pop Stars
The directors, Maggie Kang and Chris Appelhans, didn’t just pull Jinu’s look out of thin air. His design and mannerisms were actually inspired by some of the biggest names in the real K-pop world.
- Inspiration Points: Character designers looked at the stage presence of ASTRO’s Cha Eun-woo and BTS’s Jungkook.
- Visual Cues: They even used Ahn Hyo-seop’s own face as a reference for Jinu’s human form.
- The Saja Boys: The group’s name is a nod to the Jeoseung Saja, the Korean grim reapers who escort souls to the afterlife.
It’s this attention to detail that makes the character feel so "real." He feels like an idol you’d actually see trending on Twitter, which makes the reveal of his demonic true form even more jarring.
What Happens to Jinu? (The Ending Explained)
If you haven’t finished the movie, maybe look away now. Seriously.
The climax of KPop Demon Hunters is a total tear-jerker. Jinu eventually breaks free from Gwi-ma’s control because of his feelings for Rumi (voiced by Arden Cho). In a final act of redemption, he sacrifices himself to save Rumi and the rest of the hunters. His physical body disintegrates, and he is seemingly gone.
However, fans have noticed some "hints" that he might not be permanently dead. Director Maggie Kang has been a bit cryptic in Q&As, mentioning that Jinu’s soul might still exist in some form. Since the movie was a massive hit—ranking #1 in over 30 countries—a sequel is almost a certainty. Whether Ahn Hyo-seop returns to voice a revived Jinu is the million-dollar question.
How to Follow the Cast
If you’re now a certified Jinu stan, you’ll probably want to keep up with the actors behind the character.
- Ahn Hyo-seop: Follow him on Instagram (@imhyoseop). He often posts behind-the-scenes clips from his dramas, and he recently shared some "making of" footage from the recording booth for KPop Demon Hunters.
- Andrew Choi: You can find his music on Spotify and YouTube. If you liked Jinu’s songs, definitely check out his solo work—it’s got that same smooth R&B vibe.
- Maggie Kang: Keep an eye on her interviews. She’s the one who will eventually confirm if Jinu is coming back for Part 2.
