The Empire has fallen to the Demon King.
The Empire, once humanity's greatest military power, was destroyed in a single night, its past glory rendered hollow. The Emperor has passed, and fortresses everywhere have fallen. It is said the soldiers were consumed by blue flames, left with nothing but to flee in terror. Only scorched earth remains in its wake.

The tragedy was brought about by a single monster said to be a subordinate of the Demon King.
A demon clad in black armor, wreathed in blue flames that incinerate everything they touch. The "Ogre." Their power is said to surpass even that of the Demon King.
While no one could confirm the identity of this hideous beast, one rumor was whispered as if it were the truth.
──The Ogre's true identity is the First Hero.
