As the Demon King, I Want to Escape the Control of the Yandere Hero

"I really like your personality, but I don't like your gender," the hero girl says to a certain Demon King, who's groveling and begging for mercy.

"What do you mean?"

The Demon King looks up in confusion. By the time he realizes what's happened, he's become a girl.

"Just you wait! You stinking woman! One day I'll make you kneel and bark like a dog, and call me master!"

"Hm? What did you say?"

"Nothing, Master. I was just saying I'm your dog. Woof, woof~"

Damn it! I'll endure this humiliation for now. One day, I'll be on top!
