KPop Demon Hunters Singers and Voice Actors

Demon Hunters vocalists aren’t the same people who voiced their characters on the screen.

The main KPop Demon Hunters singers are EJAE, Audrey Nuna, and REI AMI, who perform for HUNTR/X members Rumi, Mira, and Zoey.

Andrew Choi, Kevin Woo, SamUIL Lee, Neckwav, and Danny Chung provide the Saja Boys’ vocals. Most musical characters have one actor for dialogue and another performer for songs. Arden Cho voices Rumi, for example, while EJAE supplies her singing voice.

Danny Chung is a notable exception because he performs both Baby Saja’s dialogue and musical parts. Here is who speaks and sings for each character.

Who Are the KPop Demon Hunters Singers?

The main musical characters generally have one actor for dialogue and another performer for singing.

The credits released by Netflix itself verify this for Rumi, Mira, Zoey, Jinu, Mystery Saja, Romance Saja, and Abby Saja.

Meet the Real Voices Behind HUNTR/X

HUNTR/X comprises three individuals, each with a separate actor and a separate vocalist. Below is what makes the three vocalists unique.

Rumi Sounds Like Arden Cho but Sings Like EJAE

Arden Cho voices Rumi in every spoken scene, but EJAE, born Kim Eun Jae, handles all of her singing.

EJAE is a Korean American songwriter who spent years training with SM Entertainment before moving into production work.

She also wrote several soundtrack songs, including “Golden,” the film’s biggest hit.

Because she shaped the songs from the ground up, her voice carries the emotional weight of Rumi’s arc, making her one of the most searched KPop Demon Hunters voice actors online.

Netflix’s official cast and soundtrack coverage identifies the actors and recording artists behind the main characters.

Audrey Nuna Gives Mira Her Singing Voice

May Hong performs Mira’s dialogue, while Audrey Nuna provides her singing voice.

Nuna is a New Jersey-based artist known for genre-blending records like TRENCH.

Audrey Nuna performs alongside EJAE and REI AMI on HUNTR/X songs such as “Golden,” “Takedown,” and “What It Sounds Like.

Nuna’s vocal texture adds range to tracks like “Golden” and “Takedown,” making her contribution one of the more distinct HUNTR/X singers on the soundtrack.

REI AMI Is the Voice Behind Zoey’s Songs

Ji Young Yoo plays Zoey in spoken scenes, but REI AMI performs her singing and rapping. REI AMI is a Seoul-born artist known for genre-crossing releases outside the film.

In the story, Zoey is written as HUNTR/X’s rapper and lyricist.

REI AMI’s rap delivery gives the character a sharper, more energetic sound than her bandmates.

Add it together, and the math is simple. HUNTR/X on the soundtrack equals EJAE plus Audrey Nuna plus REI AMI, the three real KPop Demon Hunters singing voices behind every HUNTR/X track.

Who Really Sings for the Saja Boys?

The Saja Boys also split their speaking and singing credits, with a different vocalist attached to most members.

Jinu: Ahn Hyo-seop and Andrew Choi

Ahn Hyo-seop plays Jinu in every spoken scene, giving the character his conversational tone and dramatic weight.

Andrew Choi sings all of Jinu’s parts, since Jinu is written as the Saja Boys’ lead singer and emotional center.

Choi also joins EJAE for the duet “Free,” one of the film’s quieter, more personal tracks, where Jinu and Rumi share a private moment away from the group.

Mystery Saja: Alan Lee and Kevin Woo

Alan Lee provides Mystery Saja’s dialogue throughout the film, handling his lines in group scenes and background chatter.

Kevin Woo sings for him; he’s a former U KISS member with years of K-pop group experience.

Mystery is positioned as one of the Saja Boys’ backup vocalists rather than a frontman, so his parts mostly sit within group tracks like “Soda Pop” and “Your Idol.”

Romance Saja: Joel Kim Booster and SamUIL Lee

Joel Kim Booster voices Romance Saja’s spoken scenes, bringing comic timing to a character built around charm and flirtation.

SamUIL Lee handles the musical side, a singer credited separately across the Saja Boys’ songs.

The split keeps Booster’s comedic delivery intact for dialogue while letting a trained vocalist carry the group’s more demanding musical numbers.

Abby Saja: SungWon Cho and Neckwav

SungWon Cho, known widely as ProZD, voices Abby Saja’s spoken lines and comedic beats.

Neckwav supplies his singing voice across the group’s tracks, adding a distinct tone to the Saja Boys’ sound.

Netflix describes Abby as the Saja Boys’ primary dancer, with SungWon Cho providing his speaking voice and Neckwav his singing voice.

Baby Saja: Danny Chung Does Both

Unlike his bandmates, Danny Chung handles both jobs for Baby Saja, voicing his dialogue and singing his parts himself.

Chung, who works with the label THEBLACKLABEL, also helped write “Soda Pop” and performs its rap verse in his own voice.

That makes him one of the more versatile Saja Boys singers in the cast, since he shaped the song’s writing and delivered its most memorable verse in character.

Who Performs the Main KPop Demon Hunters Songs?

The soundtrack credits identify the recording artists who perform each of the film’s main character-led songs.

• How It’s Done (HUNTR/X)- EJAE, Audrey Nuna, REI AMI
• Golden (HUNTR/X)- EJAE, Audrey Nuna, REI AMI
• Takedown (HUNTR/X)- EJAE, Audrey Nuna, REI AMI
• Soda Pop (Saja Boys)- Andrew Choi, Neckwav, Danny Chung, Kevin Woo, samUIL Lee
• Your Idol (Saja Boys)- Andrew Choi, Neckwav, Danny Chung, Kevin Woo, samUIL Lee
• Free (Rumi and Jinu)- EJAE, Andrew Choi
• What It Sounds Like (HUNTR/X)- EJAE, Audrey Nuna, REI AMI

This casting information corresponds perfectly to the real soundtrack and Netflix’s own guide for the soundtrack, meaning the same voices perform most of the songs in the movie.

Yunjin Kim voices Celine’s dialogue, while Lea Salonga provides her brief singing part. Salonga does not perform a standalone soundtrack song as Celine. Her contribution appears during the hunters’ mantra, making it much shorter than the musical roles assigned to HUNTR/X and the Saja Boys.

Other KPop Demon Hunters Voice Actors You Hear

Several supporting roles complete the KPop Demon Hunters ensemble but don’t have an individual singing voice.

Since the casting for these characters is done based on their dialogue rather than singing performances, the process is similar to a regular animated movie.

Why Do the Characters Have Separate Speaking and Singing Voices?

KPop Demon Hunters pairs actors skilled at dialogue and comedic timing with recording artists who can deliver polished K-pop vocals, a common approach in animated musicals.

This isn’t a fixed rule for every character, but it’s clear with Rumi.

Arden Cho carries her dialogue performance, while EJAE handles the demanding vocal material and even helped write the soundtrack.

KPop Demon Hunters uses separate dialogue and singing performers for many major roles.

For example, Arden Cho speaks for Rumi while EJAE provides her singing voice. Baby Saja is an exception because Danny Chung handles both.

Final Thoughts

The true identities behind HUNTR/X and Saja Boys make an equally fascinating study as the characters themselves.

The members of HUNTR/X are EJAE, Audrey Nuna, and REI AMI, while Andrew Choi, Kevin Woo, samUIL Lee, Neckwav, and Danny Chung are the vocalists behind the Saja Boys.

Even something small like the voice of Celine delivered by Lea Salonga becomes fascinating when you know who is delivering the line.

In case you enjoyed the soundtrack, you will find it rewarding to follow these artists as individuals. Watch KPop Demon Hunters on Netflix now.
