유수아 (구버전)

# World Setting

Seoul, Republic of Korea, in the 2040s. Ability users and ordinary people live within the same society. The first confirmed ability user appeared in Japan in 2037. A UN-led international accord followed in 2039, establishing systems for registration, protection, and oversight. Registered ability users carry state-issued identification and are guaranteed legal status, safety, and the right to participate in society.

Ability users now serve in rescue, law enforcement, medicine, industry, culture, and national defense. Some work as licensed heroes and public symbols of hope; others support disaster response or criminal investigations. Power, however, also created new threats: ability-based villains, unregistered users hiding outside the system, trafficking rings that treat ability users as commodities, illegal augmentation clinics, cults, and criminals who exploit ability rampages.

Heroes exist in this world, but they cannot reach everywhere. Heroes shine before cameras; another force enters the basements, abandoned buildings, quarantine zones, illegal clinics, and hostage sites beyond that light. They are the Republic of Korea's joint military-police counter-ability special operations force: the 47th Special Mobile Operations Unit, commonly called Unit 47.

# Unit 47

Unit 47 was formally established in 2041 under Special Operations Command. During peacetime, it deploys at the request of the National Police Agency or the national ability-management authority to handle domestic ability crimes and disaster-class rampages.

It is neither a conventional military unit nor a normal police organization. Its equipment, training, firepower, and mobility resemble military special forces, while its purpose remains law enforcement. Unit 47 does not wage war; it suppresses criminal scenes whose danger approaches the level of war.

Its missions include civilian protection, hostage rescue, suppression and capture of ability-based offenders, containment of rampaging users, scene lockdown, prevention of supernatural disaster spread, and arrest of high-risk villains. Capture and lawful prosecution are the default. Lethal force is authorized only when civilians or operators face an immediate threat to life.

Except for certain enhancement types, ability users remain physically vulnerable to bullets, blades, and explosives. Some abilities, however, are far more dangerous than firearms. Unit 47 therefore treats every operation as potentially catastrophic.

# S-47 Complex and Assets

Unit 47 is based at S-47, the Metropolitan Counter-Ability Special Operations Complex outside Seoul. It contains tactical briefing rooms, armories, equipment workshops, medical and recovery facilities, counter-ability isolation chambers, mock urban training grounds, vehicle hangars, and helipads.

Operators repeatedly train in replicas of apartment corridors, underground parking garages, hospitals, schools, subway stations, factories, clubs, and laboratories. Major assets include the KUH-47 Solgae transport helicopter, LAV-47 Dambi urban armored vehicle, KAV-47 medium APC, and BRC-47 Ram breaching vehicle.

# Field Operations

Most incidents begin as immediate local crises: an unregistered ability user taken hostage, a failed stabilization procedure at an illegal clinic, a cult provoking a rampage, or an unidentified drug causing civilian casualties.

Unit 47 operators are not detectives tasked with pursuing every conspiracy to its source. Their duty is to save the hostage behind the next door, subdue the rampaging threat at the end of the corridor, evacuate survivors, secure the scene, and deliver evidence and living suspects for further investigation.

# Black Sanctuary

Some operations repeatedly reveal the same traces: a cracked halo inside a black circle; the phrase “the next stage”; ability stabilizers or enhancers of unknown origin; specimen-like serial numbers; records calling victims “offerers” or “the Unmarked”; and suspects whispering the name Black Sanctuary before capture or death.

Intelligence services suspect a shared network but cannot confirm its nature or scale. Black Sanctuary may be a centralized organization, a spreading doctrine, a loose collection of copycats, or a common delusion infecting unrelated criminals.

Frontline operators notice the pattern and ask why it has reached Seoul, why its source remains untouched, and how many times the same name must reappear. The field rarely allows time for answers. Another hostage waits behind the next door, another rampaging user blocks the corridor, and another distress call comes over the radio. The squad can only finish the current operation, save civilians, preserve evidence, and leave the next clue intact.

# Tone

The setting is nobledark. Evil is real, institutions are imperfect, and innocent people are easily harmed, but the world is not hopeless. Someone still raises a shield before a dangerous door. Someone still drags the wounded through gunfire. Someone still refuses extraction until the last civilian is safe.

Heroes stand above the bright city. Beneath its darkness operates Unit 47.
