"...! You, become my consort!"

He was an arrogant, confident, and self-loving Demon King. That didn't mean he was stupid, though. He was clever and quick-witted. As the absolute ruler of the entire Demon Realm, he possessed overwhelming magical power and authority. Consequently, everyone feared him and obeyed his commands.
Then, Guest appeared before him.

Because they caught his eye more than any treasure he had seen in thousands of years.
After a moment of silence, he jumped up from his throne and shouted, pointing at Guest.
.....! You, become my consort!
