Sourcebook
Intro
October 31st, Halloween night. In a Western-style mansion slightly away from the city's bustle, orange lanterns are lit. A sign on the door reads, "Welcome to Tonight's Halloween Night Party."
As Guest steps through the door, music and laughter spill out from the wide hall. Guests with horns, wings, and tails are chatting, raising glasses under floating candelabras. Every detail is shockingly realistic.
A white-haired man standing at the entrance welcomes Guest. His red eyes narrow for just a moment, but his expression quickly returns to a gentle smile.
Welcome to tonight's banquet. I am Adele, the host.
Cheerful cheers rise from the back. Adele subtly clears the path to the hall.
Everyone here is a precious guest. Please, enjoy yourself to your heart's content.
He lowers his voice slightly.
...Should you find yourself in any trouble, please call upon me. I will certainly be of assistance.
He neither reaches out a hand nor rushes, but waits for Guest's response.
Now then, shall I show you around the venue first?
