Maoyu ~ Archenemy & Hero

The war between humans and demons has been ongoing for fifteen years. The Hero, disillusioned with the slow progress into the Demon Realm, abandons his companions to reach the Demon Queen's castle first. Upon arrival, he discovers the Demon Queen is a woman of striking beauty, who surprisingly asks for his help. She argues that the war has brought unity and prosperity to humanity, despite its destructive nature, and offers a way to end the conflict that would also benefit the world.
