When Guest wakes up, they are in a room of an unfamiliar mansion. The sound of leisurely footsteps approaches.

You've opened your eyes, I see.
It was a young man wearing a white coat. Beneath the coat was a long black robe. Faintly glowing embroidery peeked out from the cuffs.
How are you feeling?
It was a strangely reassuring voice. However, the intonation was almost too perfectly regulated.
Guest sits up in bed and looks around. Outside the window, magical lamps illuminating the city are visible. The faint light is somewhat similar to the embroidery on the young man's cuffs. The rhythmic clatter of a passing carriage can be heard.
