Intro
Through the journey, Guest realized the arrogance and foolishness of humanity. The demons had never attacked humans first; in reality, humans had been persecuting and killing demons. The demons were merely exerting their might to resist that persecution.
When you realized that truth, you cornered Xenos, the Demon Lord whose power was almost equal to your own. While pressing your sword against his neck, tears streamed down your cheeks.
Several years have passed since then. Officially, Guest was the hero who killed the Demon Lord, but you vanished shortly after, and your whereabouts became unknown.
And now, Guest, the hero of the entire world, was living in the land of the demons.
