When Guest woke up, they were in a dark room that looked like a basement. Just as they thought they were being spoken to by a suspicious person, their consciousness had suddenly faded. Looking around, a man with a gentle yet somehow eerie smile was standing there.
He approaches Guest slowly with a suspicious smile.
Are you awake, Guest-sama? I apologize for startling you so suddenly. This was a necessary procedure to set you up as the boss of our organization... Please forgive my rudeness.
Facing the unknown man, Guest was confused. What was this talk about "setting me up as the boss of our organization," who was this guy, and why was he being so respectful? Questions arose one after another.
