Ahn Hyo-seop, Aiden Cho, and Lee Byung-hun Enter Global Voice Acting Scene via Dubbing for “KPop Demon Hunters”

The success of Netflix’s animation “KPop Demon Hunters” relies on the exceptional voice acting skills of Korean actors. Actor Aiden Cho voices the main character Rumi in the series. On stage, Rumi is a perfect K-pop superstar, but in secret, she is a hunter with demonic ancestry. Having lost his mother in childhood and raised by Seline, he hides the demonic pattern inherited from his father while navigating between stages and battlefields. Aiden Cho conveyed the character’s inner struggles and growth through a calm yet firm voice. He previously starred as the protagonist “Ingrid Yoon” in Netflix’s original drama “Partner Track.” Ingrid, who aspires to become a partner lawyer at a major New York law firm, faces challenges such as the glass ceiling, racial and gender issues, and balancing family life with relationships—traits that mirror Rumi’s character. Actor Ahn Hyo-seop plays Jin-woo, the leader of the boy group Saza Boyz. Jin-woo is a member of Huntrix’s rival group and serves under the orders of Gwi-ma, making him a dual-character figure. On stage, he appears as a warm and polite star, but behind the scenes, his actions are driven by complex motives and loyalties. Ahn Hyo-seop recorded his voice in Korea, with Sony Pictures providing real-time direction and using his facial expressions in motion capture. He has consistently demonstrated versatility in dramas such as “Hongcheongi” as Haram, “Sanaemasseon” as Kang Tae-mu, and “Romantic Doctor Kim Sa-bu” seasons 2 and 3 as Seo Woo-jin. He is particularly expected to shine as the protagonist Kim Dok-ja in the film “The Reader,” set to release on July 23. In this movie, Ahn Hyo-seop plays Kim Dok-ja, the only one in a ruined world who knows the ending, working alongside the novel’s protagonist Yu Jung-hyuk (played by Lee Min-ho) to save the world. What makes it even more special is that Ahn Hyo-seop also sang the film’s theme song “Free” himself. The YouTube cover video of this duet with Rumi’s teammates surpassed 10 million views within 24 hours, and American critics praised Ahn Hyo-seop for “perfectly capturing Jin-woo’s intelligence and charisma.” Veteran actor Lee Byung-hun voices Gwi-ma, the embodiment of evil in the series. Once the ruler of the afterlife, Gwi-ma now confronts the hunters through Saza Boyz on this new battlefield of stages. Lee Byung-hun’s deep and low tone conveys weight and hidden intentions, giving his character a compelling presence that goes beyond a simple villain. He is a leading actor in Korean cinema, having starred in major films such as “Joint Security Area,” “A Sweet Life,” “I Saw the Devil,” “The Insider,” “Namsan’s Bosses,” “Concrete Utopia,” and “Sungriho.”
