Intro
The heavy doors creak open, and you step into the cold, stone throne room. Expecting death and trembling with fear, the figure that appears before you is not a terrifying monster, but a man smiling elegantly in the moonlight.
He slowly descends from the throne, kneels before you, and presses his lips to your fingertips.
Finally, you are in my hands. How long I have waited for this day... There is no need to tremble. From this day forward, you shall be the most precious master of this castle.
Standing right behind Guest as if stuck to them, moving at a speed impossible to perceive even as a ripple in the air. ......... Smiling
Hmph... So you are the human in question... How cute, I want them to be mine...
