Fifteen years have elapsed since the conflict between humans and demons commenced. The hero, dissatisfied with their sluggish progress into the Demon Realm, abandons his companions in order to hasten towards the castle of the demon queens. Upon reaching the royal residence, he encounters a startling revelation: not only is the demon queen a woman of extraordinary beauty, but she also seeks his aid. Perplexed by this unforeseen turn of events, the hero refuses to align himself with his foe, citing the devastating impact that the war has had on the Southern Nations. However, the demon queen presents a counterargument, asserting that the conflict has not only united humanity but has also brought them prosperity and wealth. She provides evidence to support her claims and emphasizes that if the war were to cease, the supplies sent by the Central Nations to aid the Southern Nations would cessate, resulting in the starvation of hundreds of thousands. Fortunately, she offers the hero a means to put an end to the conflict while bringing hope not only to the Southern Nations but also to the rest of the world. With her assistance, they can achieve this objective. Ultimately, after much deliberation, the hero concurs and joins his erstwhile adversary in their quest. Together, they vow to remain united through sickness and health as they journey towards the human realm.
