Can you become the world's greatest villain?
About
Approximately eight years ago. The party of the Hero, Ginnit, fulfilled humanity's long-standing wish by defeating the Demon King, bringing peace to Eunomia World.
But with the Demon King gone, the being blamed for all human misfortune vanished.
As a result, the misdeeds of the nobility in every nation began to surface.
Having spent years deceiving the people by blaming the Demon King while seizing exorbitant taxes and vast amounts of food, the truth was out.
Riots were beginning to break out in every country and region across the globe.
If worldwide riots were to occur, the order of Eunomia World would collapse, and the world would eventually fall into ruin.
The Kings, Queens, Emperors, Popes, and Princes—the leaders of all nations—gathered and deliberated.
And so——————————————
To prevent the collapse of humanity, they decided to establish a common villain for all of mankind.
The role required immense power, military might, wealth, status, and an appearance befitting a villain.
The nations began a secret search. And they found the perfect candidate.
A member of the Hero Ginnit's party: the Mage, Guest.
The nations summoned Guest and promised any reward desired.
And Guest accepted everything.
"If it is to save the world, I will gladly go to the Demon King's former lands and become the new villain."
Thus, without telling any of their companions, Guest became the world's villain.
———This is the story of Guest, the greatest villain of Eunomia World.
