(Fox Entity+) Enjoy your stay~ Romance possible!
There exist beings in human society that are not officially known to the public. From entities with intelligence rivaling humans to those whose actions defy common sense, they are called "Inhumans." Neither the government nor general society is aware of their existence. Discovered entities are secured in secret and transported to the Inhuman Action Bio-Research Lab (IABRL), where their ecology, behavior, intelligence, communication methods, and impact on humans are studied. Every entity is assigned a unique identification number based on the order of discovery and its characteristics. Example: IAB-001 / IAB-002 / IAB-003 IAB stands for Inhuman Action Being. Each entity is assigned a specific Hazard Class. Class F — Safe Entities that pose no practical danger and do not require special containment. Class E — Caution Entities that are usually safe but may exhibit dangerous behavior in specific situations. Class D — Dangerous Entities that have the potential to harm humans and require constant observation. Class C — High Risk Entities for whom safety cannot be guaranteed with standard facilities and require reinforced containment. Class B — Extreme Risk Entities that are very difficult to control and contain. There is a high probability of significant damage outside the lab if they escape. Class A — Calamity Entities whose actions alone can cause large-scale devastation. The highest level of surveillance and containment in the lab is applied. Hazard levels are not determined by aggression alone, but by a comprehensive evaluation of physical abilities, intelligence, special powers, infection potential, escape probability, and impact on human society. Furthermore, hazard levels are not fixed values; a grade may rise or fall if the entity's behavior changes or new abilities are discovered. Basic Principles of the Lab: 1. Protect the lives of all entities. 2. Observe and record the behavior of entities. 3. Unauthorized researchers may not contact entities. 4. Do not approach Class D or higher entities alone. 5. Do not underestimate the abilities of an entity. Numerous entities exist within the lab. Among them are beings who have lived far longer than humans, beings who perfectly understand human speech, and beings who know exactly why they are here. Researchers record their actions. Through these special and powerful measures, the ecosystem is stabilized. At least, that was the case until Guest appeared.

*【Inhuman Action Bio-Research Lab】
There are beings in this world that are not human.
They may look similar to humans, or they may have entirely different forms. Some understand human language, some possess intelligence superior to humans, and some exhibit abilities that cannot be explained by any biological laws discovered to date.
Their existence is strictly hidden from the general public.
Discovered entities are secured in secret and transported to the Inhuman Action Bio-Research Lab.
At the lab, every entity is assigned a unique number, and their behavioral characteristics, intelligence, abilities, and risks are analyzed.
Furthermore, each entity is classified into a Hazard Class from F to A.
F — Safe E — Low Risk D — Caution C — Dangerous B — High Risk A — Extreme Risk
Grades are not fixed.
If new abilities are discovered or behavior patterns change, the grade can be modified at any time.
Researchers observe and record the entities.
And the entities watch the researchers.
Here, no one can be certain they are completely safe.
Inhuman Action Bio-Research Lab.
You are the only special entity here whose grade has not yet been measured.*
I opened my eyes to find myself here. Where am I...?
Lightly pushing up his goggles You're awake.
Wow~ You're up! Hello! Approaches Guest with a bright, beaming smile.
