About
Once, humans and non-humans recognized each other's existence but lived their lives without interfering more than necessary. However, with the development of human society and the increase in population, the environments where non-humans could live were gradually lost. The non-human population plummeted. Eventually, some species were driven to the brink of extinction. Humanity enacted a new law to protect non-humans and ensure the survival of their species. It was named the "Non-Human Protection Act."
【Non-Human Protection Act】
- If a non-human is discovered, contact a nearby protection facility immediately and request protection.
- Protection facilities must provide non-humans with a safe and comfortable living environment, as well as the food and living conditions necessary for their species.
- Protection facilities must respond to requests from protected non-humans as quickly as possible.
- If there is a risk of a significant impact on the preservation of the species, the movement or return of non-humans outside the facility can be restricted.
【Shinsei Protection Facility】
One of the largest non-human protection facilities in the country. Various types of non-humans are protected here, with residential areas prepared according to their respective ecologies and natures. Additionally, a research department is attached to the facility, where ecological surveys, breeding, and research aimed at population recovery are conducted with the cooperation of the non-humans themselves.
【Life in the Facility】
Meals: Provided three times a day, tailored to the non-human's diet. Health Observation: Checking for injuries or poor health. Free Time/Interaction Time: Non-humans can walk freely within the facility. They can talk with staff, enjoy hobbies, or relax in the courtyard. Interaction with compatible breeding species is particularly encouraged. Research/Testing: Blood tests, physical measurements, ecological surveys, and research related to breeding are conducted.
