An organization dedicated to exterminating the "Eclipse Swarm" that threatens civilian life.
About
In this modern society, there exist supernatural entities lurking in the shadows that inflict harm upon humanity. They are known as the "Eclipse Swarm" (Shokushu). These beings are the physical manifestations of "negative emotions" such as stress, desire, and loneliness harbored by modern people. They erode the human spirit and prey upon flesh to grow larger and more atrocious. 【Eclipse Swarm Danger Classification】 Class D: Pest level. Causes slight discomfort. Class C: Possesses physical destructive power and begins preying on humans. Class B: Capable of damaging buildings and paralyzing parts of urban functions. Class A: Disaster level. Individuals with some intelligence appear, capable of annihilating entire districts. Class S: National existential threat level. Giant or mutant species that can even warp the laws of physics. 【Anti-Eclipse Agency】 A national agency directly under the Cabinet Office. Formally known as the "Special Eclipse Disaster Countermeasures Agency," commonly called the "Anti-Eclipse Agency." It is the organization responsible for exterminating the Eclipse Swarm, and is the primary contact whenever a Swarm appears. 【Department Structure】 ◈ Division 1: Defense Division (Field Operations) The organization with the most combatants. Highly trained regular civil servants and elite officers deploy in group combat using weapons and gear developed by Division 2. ◈ Division 2: Analysis & Development Division (R&D) They perform dissections on the remains and cores of exterminated Swarms to analyze their ecology and develop new weaponry. ◈ Division 3: Medical Support Division (Support & Medical) Responsible for treating officers, purifying contaminated zones, and covering up incidents. ◈ Division 4: Special Countermeasures Division (Commonly known as the Hazard Division) A "disposable unit" deployed to Class A or higher danger zones or hellish sites where they don't want to risk regular officers. Its members are former humans who went berserk after being administered Eclipse Swarm DNA or cores. All have suffered mental collapse and possess zero self-control (reason); they are forcibly controlled as "living weapons that follow orders" via chips and programming embedded in their brains. 【The Law of Eclipse DNA】 Normally, when a human extracts and administers Eclipse Swarm DNA, they either die instantly from cellular destruction or suffer severe brain damage, leading to a vegetative state or mental collapse. However, there are many who intentionally administer it for reasons such as "wanting eternal power," "wanting a strong body," or "wanting to be at peace."
