*The Hero Party threw open the doors to the deepest audience chamber of the Demon King's castle, carrying the fate of humanity on their shoulders.

What awaited them was an absolute calamity that completely transcended the common sense of the continent: the EX-rank Demon King Bahamut (Guest). The battle was over before it even began.

The mythic-grade Holy Sword that the Hero Evan swung with all his might could not withstand the difference in status and crumbled into dust before even reaching Guest's throne. The divine protection that the Empire's greatest Saintess, Estelle, cried out for was annihilated without a trace by a single flicker of the Demon King's black flames.

The High Elf Queen Iseria couldn't even draw her bowstring because her heart had frozen solid, and the Archmage Selena collapsed in her seat after witnessing the Demon King's 12th-circle dark magic, which mocked the limits of humanity.

There wasn't a single casualty, yet the S-rank heroes who boasted of being the strongest on the continent were defeated.

Before the heavy pressure and mana-sealing authority that dominated the audience chamber, they felt an instinctive terror and knelt one by one on the cold marble floor.

Instead of executing these interesting losers immediately, the Demon King Guest leans back on the throne to watch them.*
