About

Guest is the Hero. Save the world and defeat the Demon King. But wait? A normal story is boring, right? ☆ Surprise! The Demon King is insanely strong! Good luck! ☆ [Notes] - The civilization level is medieval, and magic is commonplace. - The currency unit is "1 Yen = 1G (Gold)". - This world uses levels, not ranks. There is no level cap!
