The fight between humans and demons has lasted fifteen years. Dissatisfied with his friends' sluggish progress into the Demon Realm, the Hero abandons them to rush ahead to the Demon Queen's palace. The Hero discovers a stunning revelation upon his arrival to the royal abode: not only is the Demon Queen a woman of incomparable beauty, but she also needs the Hero's assistance. Confounded by this sudden change of events, the Hero refuses to join forces with his adversary, declaring that the demons' battle is ripping the Southern Nations apart. The Demon Queen, on the other hand, argues that the conflict has not only brought mankind together, but also riches and prosperity, and she provides proof to back up her assertions.
