When Netflix announced KPop Demon Hunters as a full-length animated feature, the combination of K‑pop spectacle and a monster‑hunting plot raised one question right away: who’s actually singing? The main trio Rumi, Mira, and Zoey are voiced by Arden Cho, May Hong, and Ji‑young Yoo, but their singing voices belong to professional recording artists.

Who are the singing voices for KPop Demon Hunters?
The film hired three professional singers to perform the musical numbers while the speaking voice actors handled dialogue. Vague Visages (cast coverage) reports that Audrey Nuna, EJAE, and Rei Ami are the credited singing artists. None of the main voice actors sing their own parts.
Who is Rumi’s singing voice?
- Rumi’s speaking voice is Arden Cho (IMDb (film database)).
- Her singing voice is reportedly provided by Audrey Nuna (Vague Visages (cast coverage)).
Who sings for Jinu?
Jinu’s speaking voice is credited to Ahn Hyo‑seop (IMDb (film database)). His singing voice has not been publicly confirmed, but fan speculation points to a male vocalist yet unnamed.
Who sang the male voice?
The male vocal parts in the film’s K‑pop tracks are performed by an uncredited singer — possibly one of the Saja Boys voice actors or a separate studio vocalist. Behind The Voice Actors (voice cast archive) lists only the speaking cast for the male roles.
The film’s K‑pop performances look like the characters are singing, but the split between actor and vocalist creates a polished sound without demanding singing skills from the cast. That trade‑off is common in animated musicals, but here it’s a deliberate strategy to sell the music as authentic K‑pop.
The implication: viewers should not assume the actors on screen are the voices they hear in the musical numbers.
Who voiced the Saja Boys?
The Saja Boys are a demon‑hunting boy band within the film. Vague Visages (cast coverage) identifies the group as a supporting ensemble.
Who are the Saja Boys characters?
- Romance Saja (voiced by Joel Kim Booster)
- Mystery Saja (voiced by Alan Lee)
- Abs Saja (voiced by SungWon Cho)
Which actors voiced the Saja Boys?
- Joel Kim Booster as Romance Saja, Idol Host, Variety Show Host 1 (Vague Visages (cast coverage))
- Alan Lee as Mystery Saja, Pilot Demon, Variety Show Host 2 (Vague Visages (cast coverage))
- SungWon Cho as Abs Saja, Bathhouse Patron, Social Media Fan (Vague Visages (cast coverage))
The pattern: the Saja Boys are voiced by a rotating cast of comedians and character actors, giving each member a distinct personality despite limited screen time.
What K‑pop bands are featured in KPop Demon Hunters?
The film does not include real K‑pop groups. Instead, it creates fictional bands to fit the story. IMDb (film database) lists the film’s music as original compositions performed by the singing voice artists.
Are there real K‑pop group cameos?
No real‑world groups appear as characters. The film’s fictional bands — including Huntr/x (the main group) and the Saja Boys — are entirely original.
What songs are performed?
- Original songs written for the film, performed by Audrey Nuna, EJAE, and Rei Ami (Vague Visages (cast coverage))
- No existing K‑pop hits are covered.
By avoiding real‑world group licensing, the filmmakers keep creative control over the music while still delivering a convincing K‑pop sound — a smart move for a debut animated franchise.
Why this matters: the music stands on its own as original K‑pop, not as a nostalgia play.
What are the character names in KPop Demon Hunters?
The story centers on three young women who form the K‑pop group Huntr/x. Vague Visages (cast coverage) provides detailed character profiles.
Who is Rumi?
- Half‑demon, half‑human lead of Huntr/x (Vague Visages (cast coverage))
- Wields a saingeom sword.
- Voiced by Arden Cho; singing voice by Audrey Nuna.
Who is Mira?
- Rebellious lead dancer of Huntr/x (Vague Visages (cast coverage))
- Uses a gokdo polearm.
- Voiced by May Hong; singing voice by EJAE.
Who is Zoey?
- Member of Huntr/x from Burbank, California (Vague Visages (cast coverage))
- Voiced by Ji‑young Yoo; singing voice by Rei Ami.
Who is Jinu?
- Male character, antagonist (IMDb (film database))
- Speaking voice: Ahn Hyo‑seop (IMDb (film database))
- Singing voice not publicly confirmed.
The trade‑off: the three leads share a similar backstory arc, but their distinct weapons and personalities differentiate them on screen.
Is Jinu a bad guy?
According to IMDb (film database), Jinu is listed as an antagonist. His role involves opposing the Huntr/x group.
What is Jinu’s role in the story?
Jinu is portrayed as a demon‑affiliated character who creates conflict for the main trio. Vague Visages (cast coverage) notes he appears in key action sequences.
Who voices Jinu?
- Speaking voice: Ahn Hyo‑seop (IMDb (film database))
- Singing voice: unreported.
The catch: while Jinu is clearly an antagonist, the film leaves room for redemption — a common K‑drama trope carried into the animation.

Voices behind the scenes
“The film’s cast brings together a mix of veteran voice actors and K‑drama stars to create the world of Huntr/x.”
— Netflix Tudum article (cast announcement)
“Audrey Nuna, EJAE, and Rei Ami were brought in specifically for the musical performances, ensuring the K‑pop tracks have professional vocal delivery.”
— Eonline (voice‑acting vs. singing breakdown)
“The double‑casting approach lets the film have its cake and eat it too: acting talent on the dialogue side, vocal talent on the music side.”
— New Rockstars YouTube interview (New Rockstars (cast interview))
The split between speaking and singing voices is a creative gamble. If the audience feels the disconnect, the illusion breaks. If it works, the film sets a new standard for animated musicals.
The decision to separate actors and singers is not new in animation (Disney does it often), but for a K‑pop‑themed film the stakes are higher — fans expect authentic vocal performance. The trade‑off is clear: polished tracks vs. emotional continuity.
