KPop Demon Hunters Cast: Voice Actors, Singers & Characters

Animated films about demon hunters aren’t new, but KPop Demon Hunters adds a twist that cuts closer to home for music fans: the demons are posing as a boy band. Netflix’s 2025 animated feature drops a K-pop girl group called Huntrix into that exact showdown, and the casting strategy behind it is what makes the film worth watching twice — once for the animation, once for the credits. The cast blends voice actors with working K-pop singers, making every performance feel less like an impersonation and more like the real thing.

Main Voice Lead: Arden Cho as Rumi · Director Duo: Chris Appelhans, Maggie Kang · Key Singers: Audrey Nuna, EJAE, Rei Ami · Rival Group: Saja Boys voiced by demons · Release Year: 2025

Do the voice actors in KPop Demon Hunters actually sing?

The film draws a sharp line between speaking and singing voices for its lead characters — a deliberate choice that lets each performer play to their strength. Arden Cho voices Rumi’s dialogue, but EJAE handles all of Rumi’s vocals. May Hong speaks for Mira; Audrey Nuna sings her parts. Ji-young Yoo provides Zoey’s lines; REI AMI delivers her songs. This split is common in animated musicals where the speaking actor and the vocal performer have different ranges, but what sets KPop Demon Hunters apart is that the singers aren’t unknowns brought in for a single project.

Huntrix group singing roles

EJAE, Audrey Nuna, and REI AMI are credited as Billboard Hot 100 chart-toppers for “Golden,” a detail confirmed in a Billboard interview that doubles as a promotional appearance (YouTube Billboard Interview). This means the Huntrix characters don’t just lip-sync to generic tracks — their singing voices belong to artists with proven commercial credentials. The production decision mirrors how major K-pop animations often hire working idols for character vocals, lending authenticity that a studio session singer simply cannot replicate.

Saja Boys vocal talents

The demon boy band follows the same split. Ahn Hyo-seop speaks for Jinu; Andrew Choi sings his parts. SungWon Cho handles Abby’s dialogue; Neckwav covers his vocals. Kevin Woo delivers Mystery Saja’s singing lines, while Joel Kim Booster voices Romance Saja and samUIL provides that character’s singing voice (DubbingAI Blog). Danny Chung stands out as the one Saja Boys member who handles both speaking and singing for Baby Saja, the group’s main rapper and maknae (GMA Network).

Who voiced the Saja Boys?

The Saja Boys are demons sent by dark lord Gwi-ma to steal fans’ souls through the power of pop music — a premise that hinges on the voice cast selling both the charm and the menace (GMA Network). Netflix’s teaser introduced them on April 24, 2025, and the voice cast reveals why the film feels like a crossover event for K-pop and animation fans alike.

Jinu and rival members

Jinu, the leader of Saja Boys, is voiced by Ahn Hyo-seop — a casting choice reported as his first major voice acting role (YouTube Behind The Voices). His singing voice belongs to Andrew Choi, whose credits include K-pop performances in his own right. Abby Saja is played by SungWon Cho, better known online as ProZD, who also voices Abs Saja, a bathhouse patron, a social media fan, and several background demons — an unusually wide range for a single cast member (DubbingAI Blog).

Demon singer identities

The demon group’s vocal lineup reads like a showcase of niche K-pop talent: Neckwav for Abby, Kevin Woo for Mystery, samUIL for Romance, and Danny Chung doing double duty for Baby (GMA Network). Behind The Voice Actors independently confirms the core Huntrix cast — Arden Cho, May Hong, Ji-young Yoo — lending additional credibility to the English dub roster (Behind The Voice Actors).

Who is Rumi’s singing voice?

Rumi leads Huntrix on screen, and her singing voice leads the music off-screen. That role belongs to EJAE, whose Billboard Hot 100 chart-topping status for “Golden” was confirmed in a dedicated interview (YouTube Billboard Interview). Arden Cho provides Rumi’s speaking voice — a dual casting that separates the character’s personality from her vocal identity, exactly as the production designed it.

Arden Cho role

Arden Cho is known for roles across television and streaming, and KPop Demon Hunters marks one of her most prominent voice acting credits. Behind The Voice Actors lists her as Rumi’s confirmed English voice (Behind The Voice Actors), while multiple fan databases and voice actor blogs echo the same pairing. The research confidence for this specific fact is high, with three independent verification points pointing to the same conclusion.

Singing credits

EJAE’s singing credit for Rumi places the Huntrix lead in rare company: artists whose animated character work is backed by chart performance. The GMA Network feature on Saja Boys similarly anchors the film’s approach to character vocals, framing Huntrix as a “real K-pop girl group” within the story (GMA Network). The production isn’t treating these singers as hired help — it’s promoting them as the talent.

Is anyone from the KPop Demon Hunters cast from a K-pop band?

The film’s cast strategy sits somewhere between animated feature and K-pop showcase. The singing voices — EJAE, Audrey Nuna, REI AMI for Huntrix; Andrew Choi, Kevin Woo, Neckwav, samUIL, Danny Chung for Saja Boys — all have K-pop backgrounds or active music careers. The speaking cast leans more toward screen actors and voice artists, creating a deliberate contrast between performance and musical identity.

Huntrix actors with music careers

Ji-young Yoo has ties to the K-pop industry through Wikipedia-sourced references, while May Hong’s work spans multiple Asian American media projects. Neither is positioned as an idol in the film’s marketing, but both bring performance credibility that reads as adjacent to the genre (DubbingAI Blog). The strongest K-pop linkage comes from the singing cast, not the speaking cast — a choice that keeps the film’s promotional weight on the music performers.

Saja Boys K-pop ties

Kevin Woo’s status as a K-pop singer is explicit in sourcing, and Danny Chung’s dual credit for Baby Saja’s speaking and singing underscores how some performers bridge both worlds (GMA Network). Notably, no Katseye members appear in the cast — a detail clarified by BuzzFeed-style fact checks that distinguish the film’s actual roster from related K-pop entities that fans might assume overlap.

Who is singing in KPop Demon Hunters?

The complete singing roster spans both groups, with Huntrix and Saja Boys each getting distinct vocal identities. The Huntrix trio — EJAE, Audrey Nuna, REI AMI — carries the protagonist music, while the Saja Boys vocalists handle the antagonist tracks. Danny Chung is the sole performer who sings and speaks for the same character.

Full singers list

The confirmed singers are EJAE (Rumi), Audrey Nuna (Mira), REI AMI (Zoey) for Huntrix, and Andrew Choi (Jinu), Neckwav (Abby), Kevin Woo (Mystery), samUIL (Romance), Danny Chung (Baby) for Saja Boys (YouTube Billboard Interview). The Kpop Fandom Wiki also documents Korean voice actors for the Saja Boys — Min Seung-woo (Jinu), Lee Hyun (Abby), Lim Chae-bin (Mystery), Choi Hyun-sik (Romance) — though these are medium-confidence claims requiring additional official confirmation (Kpop Fandom Wiki).

Mira and Zoey voices

Mira’s speaking voice is May Hong; her singing voice is Audrey Nuna. Zoey’s dialogue belongs to Ji-young Yoo; her vocals go to REI AMI. Both casting pairs follow the same logic as Rumi’s: separate the actor’s performance from the singer’s range, and let each do what they do best.

Summary

KPop Demon Hunters earns its cast list by treating K-pop as a real craft, not a marketing gimmick. The speaking voices — Arden Cho, May Hong, Ji-young Yoo, Ahn Hyo-seop, SungWon Cho, Joel Kim Booster — bring character work to a genre that often settles for competent reads. The singing voices — EJAE, Audrey Nuna, REI AMI, Andrew Choi, Kevin Woo, Neckwav, samUIL, Danny Chung — bring chart credibility that makes the music feel earned. The film’s most interesting bet is that both audiences overlap, and the production is built around that assumption. For animation fans, the voice cast delivers range and name recognition. For K-pop fans, the singing roster delivers the authenticity that makes a demon boy band’s threat actually land.
