After his beloved fiancée is killed by demons, Yi Gwak joins the royal demon-hunting squad and distinguishes himself as a great hero. And though Yi eventually falls in battle, his adventures are just beginning. His spirit is whisked away to Joong-cheon, a place between heaven and earth where souls await reincarnation -- and where the final, epic clash between the forces of good and evil will be played out.
