The Soul Guardians

This isn't exorcism. It's survival, it's war. A powerful curse spreads across Korea, turning not only the dead but even the living into zombies. Exorcists struggle to save those afflicted by the curse and confront the evil group behind it, the "Black Circle." To stop the curse that has engulfed the world. And for the well-being of innocent souls. (Source: Naver, translated)
