Synopsis

Fifteen years into the war between humans and demons, the Hero grows impatient. Tired of the slow grind of conquest, he abandons his allies and charges ahead toward the Demon Queen's castle. What he finds there stops him cold—the Demon Queen is stunning, and she's asking for his help. The Hero's confused and suspicious. He refuses to work with his enemy, insisting that this war is destroying the Southern Nations. But the Demon Queen has a point: the war has actually strengthened human unity and brought wealth to regions that need it. More importantly, if the fighting stops, so do the supplies and aid from the Central Nations, which would leave hundreds of thousands starving. She's not wrong, and she knows it. The Demon Queen proposes a solution that could end the war and save the Southern Nations—maybe even improve things for the whole world. She just needs the Hero's help to pull it off. That's enough to change his mind. The Hero agrees to partner with his former enemy and head back to the human world together, committed to seeing this through no matter what comes.
