How the Stars of KPop Demon Hunters Became the Voices of a Global Sensation
The meteoric rise of KPop Demon Hunters has become a cultural phenomenon, not only because of its compelling narrative and groundbreaking animation but also thanks to the deeply personal connections the voice cast has with their roles. The film, a unique blend of K-pop culture, supernatural elements, and heartfelt character development, has taken the global stage by storm. At the center of this success are Arden Cho, May Hong, and Ji-young Yoo, the voices behind HUNTR/X — the trio of powerful, complex, and relatable women who lead the fight against the supernatural forces that threaten their world. Their chemistry, both on-screen and in real life, is undeniable, and it plays a pivotal role in bringing these beloved characters to life.
A Trio That Clicks: The Personalities Behind the Voices
From the moment you meet Arden Cho, May Hong, and Ji-young Yoo, it’s clear that the trio has an unspoken bond that mirrors the dynamic they share as voice actors for Rumi, Mira, and Zoey, respectively, in KPop Demon Hunters. At the Netflix offices in Los Angeles, where we sit down for an interview, their camaraderie is palpable. Each of them complements the other perfectly — Cho, poised and confident, often takes the lead in conversations; Hong, with her effortlessly cool demeanor, provides dry humor and wit; and Yoo, youthful and energetic, adds an infectious enthusiasm that keeps the mood light and fun.
As the conversation unfolds, it becomes evident that their connection to their characters goes beyond just the lines they voice. The personal backgrounds and identities of the actors allow them to connect deeply with their roles, making the experience of portraying these characters feel like a natural extension of their own lives.
Arden Cho: Embracing Leadership Through Rumi
Arden Cho’s portrayal of Rumi, the strong-willed vocalist and leader of HUNTR/X, is undeniably one of the standout performances in KPop Demon Hunters. Cho’s ability to channel Rumi’s leadership qualities, fierce determination, and vulnerability stems from her own experiences. “Rumi’s journey resonated with me on a personal level,” Cho shares. “Growing up as a first-generation Korean American in a traditional family, I felt the pressure to conform to certain expectations, and Rumi’s struggles with her adoptive mother mirrored a lot of what I went through.”
Cho reflects on the emotional weight of Rumi’s storyline, particularly her relationship with her adoptive mother, Celine (voiced by Yunjin Kim). “When Celine tells Rumi, ‘You have to hide. You can’t let them see,’ it was so familiar to me,” Cho says. “It echoed the feeling of always being told to be perfect, to fit into this mold. Voicing Rumi gave me the opportunity to express those emotions and heal.”
The connection between Cho and Rumi is deeply therapeutic, as the actress finds solace in voicing a character who is grappling with the same themes of identity, self-empowerment, and familial expectations that Cho herself faced growing up.
May Hong: Finding Rebellion in Mira
May Hong, the voice behind Mira, the rebellious main dancer of HUNTR/X, brings a cool, edgy attitude to her character that mirrors her own life experiences. “My dad was super strict growing up, and I definitely rebelled against that,” Hong shares, acknowledging the anger and frustration she often felt as a teenager. “Mira’s character embodies a lot of that rage, but also the sense of feeling trapped. It’s something I can really relate to.”
Hong’s journey toward embracing her identity was one of self-discovery, and much like Mira, she found a way to channel that rebellious energy into something positive. “When I look back on my wild child years, I realize that it was through my rebellion that I met so many different kinds of people, and ultimately, I learned more about myself.”
The depth of Mira’s character, who battles against societal expectations and embraces her individuality, was a challenge Hong took on with passion. “I think if I were more obedient, I wouldn’t have experienced the things I did, and I wouldn’t have learned so much about who I am. Mira is a perfect embodiment of that journey.”
Ji-young Yoo: Zoey’s Struggle for Self-Identity
For Ji-young Yoo, voicing Zoey, the rapper and lyricist of HUNTR/X, felt like a personal journey of self-discovery. “Zoey feels like she’s caught between two worlds, unable to figure out where she fits in,” Yoo explains. “I didn’t have to dig too deep for that because I felt the same way growing up.”
Yoo also finds parallels between herself and Zoey’s people-pleasing nature. “I often find myself trying to make everyone happy, sometimes to my detriment. Zoey’s energy, her enthusiasm, her drive to please everyone—it’s something I relate to. But there’s also a quiet strength in trying to be kind in a world that isn’t always kind.”
Yoo’s background as a daughter of Korean immigrants adds an extra layer of authenticity to her portrayal of Zoey. “I think Zoey is the kind of character who embodies strength through gentleness,” Yoo says. “It takes a lot of courage to be kind when the world around you isn’t always welcoming, and I hope I share that quality with Zoey.”
Bringing the Characters to Life: From Auditions to the Final Performance
Each of the voice actors shares a fascinating story of how they ended up playing their respective roles in KPop Demon Hunters. “I initially auditioned for Rumi, but then I was called back months later for Mira, and then, a few months after that, for Zoey,” Yoo says with a laugh. “I remember struggling with Mira because I’m not an alto, and I had to push my voice really low.”
For Hong, the audition process was simpler. “It was clear from the beginning that Mira was the role for me,” she recalls with a grin. “It was funny to audition for Zoey, though, because I had to imagine myself being super bubbly, which is so different from my usual vibe.”
Cho’s audition process was a little more unconventional. “I first auditioned for Celine,” Cho explains. “I pitched my voice low, trying to sound like an ‘adult mom.’ But when they called me back for Rumi, it was such a blessing. I had already learned so much about her from my Celine audition, and it made understanding Rumi’s character much easier.”
The Emotional Journey Behind the Scenes
The cast members also share the emotional and physical challenges they faced during the voice recording process. Hong, who had never done voice work before, recalls getting into character by focusing on her look and attitude. “I got fresh nails before my recording sessions. It really helped me get into the headspace of playing Mira,” she laughs. “It was like stepping into an ‘off-duty K-pop star’ vibe.”
For Cho, it was about tapping into music for inspiration. “For voice acting, you’re often in your street clothes or pajamas. It’s not about your appearance—it’s about how you feel,” Cho explains. “For Rumi, I’d listen to ‘bad girl’ music—anything that made me feel like a badass.”
Yoo also relied on music to get into Zoey’s mindset. “I make playlists for all my characters. For Zoey, I needed something that gave me energy because she’s so high-energy,” she says, listing off artists like K-pop groups and Kendrick Lamar.
The Unforeseen Success of KPop Demon Hunters
When the trio learned they had landed their roles, it wasn’t with fanfare. “It wasn’t romantic at all,” Yoo says. “I didn’t realize the scale this project would reach. I got the call when I was just doing something mundane like cooking lunch. There was no grand reaction.”
However, the success of KPop Demon Hunters has far exceeded anyone’s expectations. From a surprise global hit to becoming Netflix’s most-streamed movie, the cast has received overwhelming praise, particularly from younger audiences. Cho’s nephews know every line of dialogue, while Hong has received messages from children who feel represented by Mira’s character.
As the cast members reflect on their personal connections to their roles, it’s clear that KPop Demon Hunters has become something much bigger than they could have imagined. With its success and the immense impact it’s had on global audiences, the future looks bright for the trio, both in this franchise and in future projects.
