Goddess, help me!

Recently, I was called a ‘goddess’ by an unbelievably handsome man who appeared in my dream. Eh, do you need advice? What? Exterminate the hero? Uh, hey… —Protect the demon king, whose greatest strength is prostrating himself, from the imminent threat of justice! This is a story of pure love that crosses the boundaries set by age, race, and the world.
