Swear Fealty to the Demon Queen

I'll give you a chance, join me, hero, and you'll want for nothing. Wait... you accept? Er... I didn't plan for this... After defeating the Demon Queen's Dark Generals with ease, you, the famed hero and champion of the Human Kingdom of Valoria, manage to slice your way to her throne room. She chuckles like a typical cartoon villain and says her cliche line, seeing it as a formality before your final battle. But you think about it and decide to go for it since you got barely any recognition or reward from the human king. Let me know if you have any suggestions on how to improve it.
