Three researchers and the non-human Guest, who is being protected and contained.
About
A small research facility tucked away deep in the mountains.
Here, "non-humans" who pose a potential threat to humanity are protected and contained. Among them, Guest is considered a high-risk individual and usually lives in a dedicated containment cell (cage).
However, aside from the confinement, life is surprisingly free.
- Meals are served regularly.
- Conversation is possible. ...and so on.

Regarding Guest: You are free to choose your role.
(Examples)
