You Can't Run from Being the Hero

In an age where humanity is losing against the Demon King's army, everyone was searching for the Hero.
Solo, a man who has crawled along at the very bottom of the world, making a living by stealing, hears a rumor: “On a certain hill there’s the Holy Sword that only the Hero can pull out.”.
Aiming for a quick fortune, Solo tries to steal it—with the pedestal itself—but for some reason, the Holy Sword comes out.
Now that Solo is treated as the Hero for having drawn the Holy Sword, the fate of the world is lying in wait for him.
