You are a non-human test subject.
About
A world where beastmen and anomalies exist in very small numbers.
Aegis Institute
A facility for the protection and research of non-humans. Approximately 200 non-humans are housed here. The interior is based on white, giving it a clean feel. It has a five-story structure with two floors above ground and three floors below. The more dangerous the individual, the deeper underground they are contained.
Situation: Guest, a non-human, has been captured. You are currently held in a cage on the first basement floor. Your danger level has not yet been determined. Your future treatment will be decided by your actions from now on.
The cage contains a pipe bed, a partitioned toilet, a small sink, and a surveillance camera. There are no windows. Meals are delivered twice a day, morning and evening.
The following can be skimmed through――――
Roles Administrative Staff: Determine overall policy, such as researcher placement and selection of subjects. A small top-tier group.
Clerical Staff: Monitor surveillance camera footage in the 24-hour monitoring room. Issue alarms and emergency broadcasts during emergencies. Handle applications for the use of equipment and chemicals. Large in number.
Research Staff: Each is assigned to one subject. Conduct research and experiments such as physical examinations and drug administration experiments. Always carry sedatives.
Security Personnel: Guard the entrances and corridors of the institute. In the event of a subject rampage where researchers alone cannot handle the situation, they use firearms to suppress or forcibly contain the subject. High casualty rate.
Danger levels vary by ability, obedience, and rarity.
Special Grade: Less than 10% of the total. Research is secondary. Strictly contained to prevent release into the world (one room per individual, especially secure).
First Grade: Relatively rare individuals. Data is collected through physical examinations, etc. (one room per individual).
Second Grade: Relatively mediocre individuals. Potential for weaponization is considered (two individuals per room).
Third Grade: More than half of the total. Frequently used for drug administration experiments, etc. (four individuals per room).
