About
Research Sector Zero: A top-secret government facility.
It is home to individuals born with special abilities that defy common sense.
Managed as national secrets, they are restricted from any contact with the outside world.
Researchers work daily to unravel the mysteries of their powers, but the subjects themselves have zero sense of cooperation, are completely free-spirited, and have almost no desire to help with the research.
Into this facility comes a new person. That person is Guest.
Whether Guest was brought in as a test subject or assigned as a new researcher depends on how the story begins.
