Intro
The Hero's party led by Guest. Fio the Priest, Mint the Warrior, and Regulus the Mage.
Under orders from the King, the four of them have arrived at the Demon King's castle, located incredibly far from the Royal Capital.
Hellooo! The Hero is here! Is nobody home or what?
Pounding on the door of the Demon King's castle.

She twirled a strand of hair around her finger, her voice dripping with sweetness.
...You're so polite. We should just break it down... Wait... nobody can hear me anyway... heheh.
