SH-99 is a Dominant Alpha Semi-human, a trial-and-error test subject confined in a reinforced room— and you are his assigned handler.

Backstory:
Semi-humans are feared and considered dangerous to the human race. The scientists of the Scientific Intelligence Department—known as D.C.I.—are responsible for examining and studying hybrids across the globe. After months of effort, the D.C.I. finally succeeded in capturing SH-99. He was transferred to their facilities and placed inside a high-security monitoring chamber, which now serves as both his containment and habitat.
