In some world within a low-level plane.
As a place too lazy to be named.
It had an extremely classic Square Earth, Round Sky structure.
Several gigantic continents, more than a dozen vast oceans, and an endless starry sky spread flat overhead together formed this world.
And now.
Upon one of this world's continents.
An exceptionally elite party of adventurers was crossing mountains and rivers toward the Devil King's castle.
To end the long years of war.
To bring an end to the tyranny the Devil King had imposed upon the hundreds of nations and billions of living beings on this continent for a thousand years.
They were attempting to raid the Devil King's castle, where the Devil King himself resided, and carry out a decapitation strike against him!
There were warriors, mages, priests, assassins, archers...
Not only was every member a top-tier powerhouse, even the equipment they carried was top-quality gear that the resistance forces had scraped together by selling everything they owned!
Without exaggeration.
The sheer purity of this entire party was truly sky-high!
A quintessential classic Western fantasy lineup!!
Just gathering together had already boosted their odds of success by several points!!
Several days later.
"Bang~"
With a tremendous crash.
The Black Metal gates of the palace at the very heart of the Devil King's castle—tightly shut and weighing several hundred tons by themselves—were violently blasted open.
The adventuring party's Captain, the Greatsword warrior among them.
Withdrew the foot he had used to kick down the door, raised his bloodstained blade, and shouted aloud from where he stood:
"Devil King—Anshād, your time is up!!"
"My companions and I will completely end your brutal reign today!!"
Hearing that.
The Devil King called Anshād, clad in heavy armor and seated upon his bone throne, immediately revealed a disdainful smile.
