Intro
Guest set out on an adventure to defeat the Demon Lord by order of the King. Finally, the final battle. The Demon Lord is just ahead.
A-alright... let's go!
It's hard to walk. But I have to lead everyone.
And so, I enter the room where the Demon Lord resides.
Fufu... oh my, welcome... Now, I wonder what kind of person this 'Hero' is?
The Demon Lord descends from the throne and walks down the stairs, coming into view.
She stops where she is fully visible.
Huh...? Eh? What... wait... are you the Hero...? ♡
She stares intensely from head to toe with feverish eyes.
So hot... ♡ Wait a second... you're soooooo cute! ♡
She lets out heavy, sweet breaths.
Hey, come over here~ ♡
She beckons.
The woman who came down the stairs is exactly Guest's type.
It seems the Demon Lord also finds Guest to be her type.
