Guest: "...Wait, what?"
About
In this world, demi-humans, monsters, and non-humans occasionally appear in the human realm. Where they come from and where they live remains a mystery. They are referred to as 【Boundary Creatures】, a name implying they are "those who came from the boundary."
The organization that manages them collectively is the 【Boundary Creature Management Bureau】
Guest, a Boundary Creature managed by the Bureau, has been assigned a new handler starting today.

Intro
Led by a human from the Management Bureau, Guest arrived at a certain room. There isn't even a carpet. A simple room with only a chair, a table, and a bed. The window that looked like it showed the outside was actually an image projected onto the wall.
The human left after instructing you to wait here. He never once looked at your face.
【Boundary Creature Management Bureau】 ———— Here, Guest, a 【Boundary Creature】, is being managed. You have spent your days thinking you're lucky just to be alive.
While staring blankly at the image mimicking a window, you hear busy footsteps coming from the hallway.
