NETFLIX CAST GUIDE
Meet the KPop Demon Hunters cast, including the HUNTR/X voice actors, singing voices, Saja Boys, demons, mentors, and Netflix character guide.
KPop Demon Hunters became one of Netflix’s biggest animated conversation starters by mixing K-pop performance, demon-hunting fantasy, Korean mythology, action, comedy, and a high-energy soundtrack. The movie follows HUNTR/X, a global K-pop girl group whose members are not only idols on stage but also secret demon hunters protecting the world through music.
Because the movie blends voice acting and music, the KPop Demon Hunters cast is especially interesting. Some main characters have speaking voice actors, while the HUNTR/X performance vocals are handled by artists connected to the film’s songs. That means fans often search not only “who voices Rumi?” but also “who sings for Rumi?” or “who are the HUNTR/X singing voices?”
This Cast Radar guide breaks down the confirmed voice actors, characters, singing voices, villain roles, supporting cast, where you may know the actors from, and why this Netflix animated musical became such a major fan favorite.
KPop Demon Hunters Cast Table
The table below gives a quick look at the main KPop Demon Hunters voice actors and characters. Because the film is a musical, the table also notes important singing voices where they are central to the character’s performance identity.
Main KPop Demon Hunters Voice Actors and Characters Explained
Arden Cho as Rumi
Arden Cho voices Rumi, one of the central members of HUNTR/X. Rumi is not just a performer; she is part of a legacy of singers who use their voices and performances to fight demons. That makes her both a pop idol and a warrior, which is the exact combination that gives the film its unique energy.
Cho is a strong fit for the role because she has a background that connects acting, music, Korean-American identity, and genre storytelling. Many viewers know her from Teen Wolf, where she played Kira Yukimura, or from Partner Track. Her performance as Rumi needs to carry confidence, stage presence, emotional pressure, and the sense of someone protecting more than just her career.
Rumi’s singing voice is performed by EJAE, whose vocals became closely associated with HUNTR/X’s musical identity. That separation between speaking voice and singing voice is common in animated musicals, and it allows the character to work dramatically in dialogue while also sounding like a polished K-pop performer on stage.
May Hong as Mira
May Hong voices Mira, another member of HUNTR/X. Mira brings style, edge, and performance energy to the trio. In a movie built around group chemistry, every member needs a clear personality. Mira helps make HUNTR/X feel like a real idol group rather than just three interchangeable heroes.
Hong’s performance gives Mira a cool, stylish energy that works well with the movie’s concert visuals, fashion influence, and action sequences. The character is part performer, part fighter, and part sister-in-arms. That balance is important because HUNTR/X must work as both a believable music act and a demon-hunting team.
Mira’s singing voice is performed by Audrey Nuna, whose vocals add another layer to the group’s sound. For fans of the soundtrack, Mira is not only a character in the story but also part of the fictional musical identity that helped the film break out online.
Ji-young Yoo as Zoey
Ji-young Yoo voices Zoey, the youngest member of HUNTR/X and one of the film’s most energetic personalities. Zoey brings humor, sharpness, and youthful confidence to the group. Her presence helps balance the heavier fantasy mythology with a lighter, more playful character voice.
Yoo has gained attention for roles in projects such as Expats and Smoking Tigers. In KPop Demon Hunters, her role gives her a chance to work inside a bright, music-driven animated world where personality has to come through quickly.
Zoey’s singing voice is performed by Rei Ami, adding a distinct musical flavor to the HUNTR/X trio. Together, the speaking and singing performances make Zoey feel like a complete pop-idol action heroine rather than just a side character.
Ahn Hyo-seop as Jinu
Ahn Hyo-seop voices Jinu, a key member of the rival Saja Boys. Jinu is important because the Saja Boys are not just a competing boy band; they are tied to the demon threat that HUNTR/X must face. That gives Jinu a layered role inside the movie’s mix of music, rivalry, danger, and fantasy.
Ahn Hyo-seop is widely known from K-dramas including Business Proposal and Dr. Romantic. His casting gives the film major appeal for fans of Korean dramas and Korean entertainment. That matters because KPop Demon Hunters draws heavily from Korean culture, K-pop aesthetics, idol fandom, mythology, and modern Seoul-inspired visuals.
Jinu’s role also adds emotional tension because a rival idol group naturally creates competition, attraction, suspicion, and performance pressure. When that rival group is secretly demonic, the stakes become much higher.
Yunjin Kim as Celine
Yunjin Kim voices Celine, a mentor figure connected to Rumi and the demon-hunting legacy. Celine gives the story a sense of history. HUNTR/X may be young and globally famous, but they are part of a much older tradition of singers using music as protection against dark forces.
Kim is known internationally for Lost, where she played Sun-Hwa Kwon, and for major Korean and international projects. Her voice brings maturity and emotional weight to the film. In stories about young heroes, mentor characters are essential because they connect the present-day action to the deeper rules of the world.
Celine’s presence helps explain why the demon-hunting mission matters and why Rumi’s role is more complicated than ordinary pop stardom.
Lee Byung-hun as Gwi-Ma
Lee Byung-hun voices Gwi-Ma, the demon king and one of the film’s major villain figures. Gwi-Ma represents the supernatural threat behind the demons and the danger facing the world if HUNTR/X fails.
Lee Byung-hun is one of Korea’s most internationally recognized actors, with roles in Squid Game, Mr. Sunshine, I Saw the Devil, and Hollywood films including G.I. Joe. His voice gives Gwi-Ma authority, menace, and prestige.
A strong villain voice is essential in an animated fantasy musical. HUNTR/X may provide the glamour and music, but Gwi-Ma provides the darkness that makes their mission matter.
Ken Jeong as Bobby
Ken Jeong voices Bobby, the group’s manager. Bobby adds comedy and entertainment-industry energy to the movie. In a story about a K-pop group, a manager character is important because he connects the performers to schedules, publicity, pressure, and the chaos of fame.
Jeong is known for Community, The Hangover, Crazy Rich Asians, and many comedy roles. His performance helps ground the supernatural story inside the frantic machinery of entertainment. HUNTR/X may be saving the world, but they still have appearances, fans, expectations, and public images to manage.
Daniel Dae Kim as Healer Han
Daniel Dae Kim voices Healer Han, a supporting character connected to the film’s fantasy and mythology side. Kim’s voice brings calm authority and experience, which makes him a natural fit for a character who may guide, heal, or explain parts of the supernatural world.
Kim is widely known for Lost, Hawaii Five-0, and voice roles including Avatar: The Last Airbender projects. His presence adds another major Korean-American screen name to the cast and strengthens the film’s cross-cultural appeal.
Who Are the HUNTR/X Singing Voices?
One of the most searched parts of KPop Demon Hunters is the difference between the speaking voice cast and the singing voices. HUNTR/X works as a fictional K-pop group because the songs feel like real pop performances, not just background music.
The main HUNTR/X singing voices are EJAE for Rumi, Audrey Nuna for Mira, and Rei Ami for Zoey. Their performances helped turn the fictional group into a real-world music phenomenon among fans of the film.
This is one reason the movie became so sticky online. Fans were not only watching the story; they were replaying the songs, sharing clips, learning the lyrics, and treating HUNTR/X like a real pop group. For a music-driven animated movie, that is exactly the kind of crossover success every studio wants.
What Is KPop Demon Hunters About?
KPop Demon Hunters follows HUNTR/X, a famous K-pop girl group that leads a double life as demon hunters. By day, they perform for fans, make music, and live inside the demanding world of idol fame. Behind the scenes, they fight demons and protect the world using magical music tied to an ancient barrier.
The group faces a major challenge from the Saja Boys, a rival boy band whose members are secretly connected to demonic forces. That setup allows the movie to combine idol rivalry, fantasy battles, comedy, stage performances, and supernatural mythology.
The idea works because K-pop already has a strong visual language: choreography, styling, fandom, music videos, lightsticks, concerts, and group identity. The movie turns that language into action-fantasy storytelling. Singing is not just performance; it is power.
Why KPop Demon Hunters Became So Popular
The popularity of KPop Demon Hunters comes from how many audiences it speaks to at once. K-pop fans connect with the idol-group structure, music, performance styling, and fandom energy. Animation fans connect with the action, color, character design, and fantasy world. K-drama and Korean entertainment fans recognize several actors and cultural references.
The movie also arrived at the right time. Global audiences are already familiar with Korean pop culture through music, dramas, beauty trends, food, and streaming hits. KPop Demon Hunters packages that cultural energy inside a fast, accessible animated fantasy movie.
Another major reason is the soundtrack. When songs from an animated film become replayable outside the movie, the film gains a second life. Fans return to the songs, discover the singers, make edits, share clips, and keep the characters alive online.
