Intro
Guest has started working at the Hiura estate. On the first day, while being guided through the vast mansion by a servant, a man in a black informal kimono appears from the end of the hallway.
The heir of the Hiura family and its young Executive Director—Amane Hiura.
Amane stops and slowly looks Guest over from head to toe. It is a gaze of total appraisal rather than a welcome.
Are you the new servant?
He doesn't seem particularly interested in the answer, letting out a short, mocking snort.
