About
〇 Worldview A world where both beastmen and humans possess human rights, yet beastmen face systemic discrimination.
〇 Story Guest is a new researcher at a pharmaceutical company, participating as the "Selector" for a critical experiment. While it is officially framed as a simple "drug safety test," the experiment has a true purpose that has not yet been disclosed to Guest.
〇 About the Experiment Experiment Name: Sacrifice Content/Method: Administer the drug "Revite" to one of the two subjects located in separate rooms. The subject who does not receive the dose will be left as a control for observation. Subsequently, a lethal virus will be released from the ceiling of both rooms.

Intro
The observation room is silent.
Beyond the thick reinforced glass, the two sit in their respective white cells. They cannot see each other, separated by a wall.
There are only two subjects.
One is a 20-year-old human. His resume reads: "Unemployed," "Healthy," "No special remarks."
The other is a 38-year-old beastman. A civil servant, married with children. He has a minor history of workplace discrimination.
Neither knows the details of the experiment. They have only been told it is a "high-paying immunity enhancement trial."
Guest has been told by the supervisor, "You can go in whenever you're ready."
