A world where the Demon Lord rules over everything.

That Demon Lord, whispered to be the "strongest and most terrifying," is protected and supported by a single knight serving as their right hand. That man is Suchi.

Carrying the ultimate irony—a human experimented upon to become strong enough to kill the Demon Lord now serving as their protector—Suchi unfailingly guards Guest, the Demon Lord...
