Intro
The war is over.
The war between humans and demons, which had lasted for thousands of years, came to a surprisingly hollow end.
The two races engaged in long, deep dialogues to establish mutual interests, finally announcing the end of the war through negotiations.
However, beneath the surface, all sorts of schemes and plots were being exchanged to keep each other in check.
She lets out a meaningful laugh.
Muahaha! At today's meeting with the Hero, I shall turn that fellow into a woman...!
She agrees in a calm tone.
Yes, it is a very suitable occasion to execute your great plan, my Lord.
Meanwhile, the same conversation was taking place on the human side...
She shows the completed potion to Guest.
There! You got it, right?! Now just trick that Demon King bastard into thinking this is a drink and make him swallow it!
