About
☆ You have become a test subject at a certain research facility.
○ Aetrium Research Institute (About this place) ・This is an organization dedicated to the "Observation," "Capture," and "Protection" of non-human entities.
〜 Observation 〜 ・Observation involves investigating captured or protected non-humans. ・For example, finding preferred environments, favorite foods, and countermeasures for the entities. Commonly known as the Observation Division. Consists of about 200 members.
〜 Capture 〜 ・Capturing and suppressing non-humans that are rampaging in human living areas or causing environmental harm. ・Their job also includes capturing and suppressing entities that cause containment breaches. (*Breached entities are processed in secret, so the general public is never in danger.) Commonly known as the Capture Division. Consists of about 330 members.
〜 Protection 〜 ・Bringing non-humans with nowhere to go or safe entities to the institute. ・Protected entities are granted a certain degree of freedom. Commonly known as the Protection Division. Consists of about 50 members.
○ Danger Levels ・Danger levels are identified from D to K.
Class K: The class containing the most dangerous non-humans. This class has the fewest entities. They are contained deep within the institute. In the event of a containment breach or escape from the institute, the entire Capture Division is deployed. Since restraints are ineffective, even observation is difficult.
Class S: A class containing highly dangerous non-humans. Contained in the lower levels of the institute. Containment breaches occur, but escapes from the institute are blocked by the Capture Division. Since some entities are immune to restraints, observation is severe.
Class A: A class containing very dangerous non-humans. Contained in the central part of the institute. Containment breaches are rare, but they pose obstacles to observation. However, observation is possible if they are restrained.
Class B: A class containing moderately dangerous non-humans. Contained in the central part of the institute. Containment breaches occur very rarely. Caution is required during observation.
Class C: A class containing non-humans that are not very dangerous. Contained in the upper levels of the institute. Almost no containment breaches occur. There are no particular obstacles to observation.
Class D: A class containing safe non-humans. Contained in the upper levels of the institute. They do not cause containment breaches and pose no danger. They do not attack even if humans approach, so they have a lot of freedom.
○ What is a Containment Breach? ・When a subject (non-human) escapes from its containment cell.
○ Containment Numbers ・The more dangerous the entity, the higher the number. Maximum is 10,000. Example: B-4580 for a Class B entity, C-559 for a Class C entity.
