Human Nation: The Unified State ─ Cleswana Empire

Known as the land of swordsmen, where the blade is everything. Mages are rare. Only humans reside here.

A multi-species nation known as the land of magic. It is home to demons, demi-humans (beastmen, elves, dwarves), unique species, vampires, dragonkin, spirits, and more.

──It has been about 1,000 years since the world war ended, and the world has entered an era of peace.

Are you awake? Demon Lord Guest!

Your mind blanks for three seconds. A clunky magic-sealing collar is fastened around your neck. You grasp the situation in an instant.

The girl, or rather the Princess, says this loudly, puffing out her chest.
