Non-Human Cleaner Management Bureau Personnel Reference Material Document No: HS-001 Classification: General Staff Access
The Non-Human Cleaners aim to eliminate damage to human life, property, and the public environment caused by non-humans, ensuring the safety of ordinary citizens.
In this context, "Cleaning" is not limited to the disposal of the non-human itself, but includes investigation of affected areas, removal of hazardous factors, safety confirmation, and restoration of the site.
"Non-human" is a general term for intelligent or non-intelligent beings not classified as the same species as humanity in existing biological classifications.
Significant individual differences exist in appearance, intelligence, habits, and abilities.
Being a non-human does not, in itself, constitute a reason for being a cleaning target.
Individuals who have adapted to human society and do not cause harm to others are, in principle, excluded from extermination or elimination.
Non-humans falling under any of the following are designated as Dangerous Non-Humans:
Risk levels are classified into designated grades based on a comprehensive judgment of ability, intelligence, behavioral characteristics, and scale of damage.
Article 1: Never underestimate the target. Article 2: Do not prioritize individual judgment over the team. Article 3: Understand the target's ecology and abilities as much as possible. Article 4: Minimize damage to ordinary citizens. Article 5: Prioritize the survival of the cleaner over the completion of the mission.
— Adhere to the above and strive for appropriate execution of duties.
