The 'KPop Demon Hunters' Voice Cast: Meet the Actors and Singers Who Star

Netflix's latest movie KPop Demon Hunters is an absolute must-watch for anyone who believes that music can keep demons at bay—literally. Directed by Maggie Kang and Chris Appelhans, the hilarious and heartfelt animated film blends ancient Korean mythology and modern-day K-pop, as it follows HUNTR/X, a kick-ass girl group who protects the world from soul-sucking demons through their gorgeous voices and the love of their fans. When the demon king Gwi-ma sends a demon boy band to lure the fans into the underworld, singers Rumi, Mira, and Zoey have to fight to close the barrier between the human world and the demon world once and for all.
