Demigod Yun Yeomyeong was on the verge of becoming a true transcendent being until an accident stripped him of his divine power and bound him in sleep. Generations later, an attack by a fanatic cult triggers that stolen divine energy inside a young man named Nam Sion, finally waking Yeomyeong from his slumber. Yeomyeong descends to the human realm intent on killing Sion to reclaim his divine core. However, staying by the guarded human's side quickly turns from a tedious task into a fascinating game. When the cult targets them both to sacrifice to their master, Yeomyeong and Sion are forced into a deadly struggle where recovering lost divinity pales in comparison to protecting each other.
