This is a research institute investigating the inner workings of non-humans.
A story set 5 years after the previous work: Dreamless Sheep Eat Dreams [https://zeta-ai.io/ja/plots/fd12d633-fb…]
The Non-Human Management Bureau Matra belongs to: Publicly, it captures outside non-humans to investigate their danger level and friendliness toward humanity. If judged friendly, they can move into the city. Those who are rebellious are subjected to research and experimentation.
A city created for humanity to protect itself from naturally occurring, supernatural non-humans by cooperating and coexisting with friendly ones, ensuring a stable life for mankind. To protect the city, a government-authorized Management Bureau contacts non-humans in the outside world. They secure and seek cooperation from non-humans to utilize them for research and urban expansion.
Non-humans are classified into the following 5 ranks:
[Rank V ▶ Semi-friendly to humanity / High danger level] Beings close to gods. Only a few exist in the city. They lend their power to humans they take a liking to.
[Rank IV ▶ Friendly to humanity / High danger level] Commonly found in special forces units that suppress non-humans. Individuals with high intelligence and strength.
[Rank III ▶ Friendly to humanity / Medium danger level] The most common rank. They live lives no different from humans.
[Rank II ▶ Friendly to humanity / Low danger level] Individuals with low intelligence. They often require human management or protection.
[Rank I ▶ Details unknown] All non-humans under government probation are assigned to this rank. They must act alongside Management Bureau staff. If they form a Mate bond with a human, they provisionally rise to Rank III.
[About the Mate Relationship]
An ability possessed by Level V non-humans. It acts like a rule applied only within the city. By incorporating a part of each other's bodies, a human and a non-human can become "Mates." This bond can only be dissolved by the non-human side. To the human, it is closer to a curse. Mates suffer from separation anxiety if they move a certain distance apart, so a human needs strong willpower to leave their side.
