After the Demon King was sealed by the united races of the continent, Dirok, a puppet master and one of the former Four Heavenly Kings, came to see him.
"Your Majesty, I've made you a custom body. Attach yourself to it and you'll be able to break out of the seal!"
"Ha ha ha! As expected of my most capable subordinate. When I return, you'll be crown prince!"
"Wait, why is this body a female succubus?!"
"What's this pretty pattern on my lower abdomen? Why do you smell so good?"
"Ah, why can't I move more than twenty meters away from you?! Get me back into my old body at once!"
By the time the Demon King realized something was wrong, she had no choice but to live as a succubus...
"I miscalculated. I never thought His Majesty would still be so powerful as a succubus!"
The puppet master Dirok stumbled into a clinic, leaning against the wall. "Doctor, do you have any medicine? Please save me!"
