EJAE: The Singing Voice Behind Rumi in KPop Demon Hunters. EJAE, the powerhouse Korean-American singer-songwriter, brings Rumi’s songs to life in KPop Demon Hunters. Discover how her journey from rejected trainee to Netflix star reshaped K-pop storytelling and gave rise to one of animation’s most unforgettable voices.
The Viral Mystery: Who’s That Voice?
If you’ve scrolled through TikTok lately, you’ve seen it: glowing neon edits, dance trends, and reaction clips from KPop Demon Hunters. The Netflix animated hit dropped like a supernatural bomb merging fierce K-pop girl groups, demon-slaying battles, and soundtrack bangers that refuse to leave your head.
But as fans gush over Huntress, Saja Boys, and Rumi’s fierce confidence, one question keeps surfacing:
“Who’s the voice behind Rumi’s breathtaking vocals?”
Spoiler alert it’s not just Arden Cho who brought Rumi to life. The soulful, high-reaching vocals those that light up songs like “Golden” and “How It’s Done” belong to EJAE, a 33-year-old Korean-American singer-songwriter who’s spent years shaping K-pop from behind the curtain.
Industry insiders call her “the Benny Blanco of K-pop”, but now the secret weapon has stepped into the spotlight.
From Trainee Heartbreak to Hidden Hitmaker
Imagine being twelve and stepping into Seoul’s most competitive dream machine. That was EJAE real name Kim Eun-jae when she joined SM Entertainment’s trainee program. For a decade, she chased her idol dream with every ounce of effort: relentless vocal training, choreography, dieting, and rehearsals.
But in the brutal world of K-pop, talent doesn’t always guarantee a debut. While her peers joined glittering groups, EJAE was told she didn’t fit the mold. Then came the final blow: “You’re too old.”
Just like that, the dream she’d built her life around shattered.
Most would have walked away EJAE reinvented herself.
She moved to Brooklyn, adopted the name EJAE, and found her voice not in performance, but in songwriting. Her turning point? Co-writing the hauntingly beautiful “Psycho” for Red Velvet under the very same SM Entertainment that had once rejected her. The song became an international hit, went gold in the U.S., and solidified her as one of the most respected ghostwriters in K-pop.
Soon, her name quietly appeared behind hits for TWICE, aespa, LE SSERAFIM, and NMIXX. EJAE wasn’t chasing fame she was building it for others.
“Fans started calling her the Benny Blanco of K-pop, a nod to her uncanny ability to craft hits then duck the cameras.”
The Call That Changed Everything
When Netflix and Sony teamed up to create KPop Demon Hunters, they wanted music that could bridge authentic K-pop energy with cinematic drama. They hired EJAE to write a few demo songs. But when the directors heard her sing, they knew they had found something special.
Co-director Maggie Kang told Forbes that EJAE’s demo recordings were “fundamental” in shaping the project. Her voice raw, emotional, and versatile became the heartbeat of Rumi’s musical journey.
What began as background songwriting quickly evolved into EJAE performing Rumi’s full singing parts. Her range and emotional authenticity perfectly matched Arden Cho’s dialogue delivery, creating a seamless dual performance.
“EJAE wasn’t just Rumi’s singer,” Kang said. “She was Rumi.”
From Demos to Demon-Slaying Anthems
EJAE’s involvement went far beyond vocals. She co-wrote and restructured much of the soundtrack, layering Korean and English lyrics with traditional Korean instruments and supernatural beats. Her goal was to make every song part of the story, not just background music.
The workload was intense over 50 versions of the opening track “How It’s Done” were tested before the team settled on the final version. EJAE worked from studios, hotels, and even Airbnbs, sometimes recording in the quiet hours of the night.
“I was in Japan for a trip… They’re like, ‘Hey, you have to finish this song.’ I was like, ‘All right, Japan’s quiet.’ I put my headphones on, sang my heart out and when I took them off, I heard someone else singing along.”
Songs like “Golden,” “Your Idol,” “Demon Dance,” and “How It’s Done” became anthems of identity and empowerment. “Saja Boys,” the villainous theme, flipped toxic fandom culture into a darkly seductive dance hit.
The result? A soundtrack that dominates both Spotify’s global charts and Billboard’s Top 50.
The Emotional Core of “Golden”
The viral hit “Golden” is more than a soundtrack song it’s EJAE’s personal anthem. It mirrors her journey from rejection to redemption:
“We dreaming hard, we came so far / Now I believe we’re going up, up, up.”
In an interview with Genius Korea, EJAE admitted the song was deeply autobiographical. She said,
“I came a long way. I think I needed a song that helped me believe I’d make it someday.”
Recording it brought tears. Every line carried her past the fear, the pain, and the defiance to rise again.
When fans sing along, they’re not just chanting Rumi’s triumph. They’re echoing EJAE’s comeback story.
How EJAE and Arden Cho Crafted Rumi Together
EJAE and Arden Cho, who voiced Rumi’s dialogue, collaborated closely to ensure consistency between spoken and sung moments.
EJAE studied Cho’s tone and cadence to mirror her emotional rhythm. The result: a seamless voice blend where listeners often can’t tell where Cho’s acting ends and EJAE’s singing begins.
The film’s producers praised their teamwork, noting that this emotional sync elevated Rumi’s performance to cinematic brilliance.
“We wanted audiences to believe that Rumi was real and when she sang, you’d feel her pain, not hear a recording,” EJAE explained.
Songs That Define Rumi’s Journey
