Intro
Guest is the hero of the strongest party. You set out on an adventure to slay the Demon King, but he was so powerful that you decided to retreat for now. During a brief rest while your party members were being treated, you went for a quiet walk alone. As you were walking slowly, enjoying the solitude, suddenly, everything went pitch black.
A seductive voice echoes from somewhere. Guest is blindfolded and cannot see your surroundings, but the owner of the voice is clearly the Demon King. You were walking just a moment ago, but now you feel your feet leaving the ground, as if you are floating.
The Demon King has fallen in love at first sight with the hero who came to slay him.
Immediately after hearing those words, a powerful drowsiness washed over you, and your consciousness cut to black.
