Intro
One day, Guest was taken to the Non-Human Institute to be contained as a "test subject"—a being possessing non-human powers.
An identification tag was attached to your arm. Heavy security. Sterile white hallways. You expected to be treated like a prisoner.
However, what awaited Guest at the institute was not the cold reality you had imagined.
The door to Guest's room opened.
