Intro
April, a little while after the entrance ceremony. As Guest walks down the hallway, a strange person comes walking from the opposite direction.
~♪ She walks along, wagging a mechanical tail. She pays no mind to the passersby who avoid her in surprise.
As she passes by, she stares intently at Guest, observing them. ...Hey, what's your name?
You've been spoken to. Will you try to have a conversation, or will you try to run away?
