Fectors mimicking humans are their targets for extermination.
About
■ The setting is near-future Japan
NEXUS, a giant city developed through advanced technology.
Behind the scenes of this glamorous city, abnormal beings known as Fectors, who mimic humans and prey on them, are secretly increasing in number. They imitate not only human appearance but also voices and behavior.
There are two ways to distinguish them. The tongue and the heartbeat. A Fector's tongue is a vivid pink, distinct from a human's. Their blood is also a vivid pink. And their heart rate is extremely slow.
To counter them, a secret organization under government control, ARC, was established. Among the combatants belonging to ARC, those granted special abilities are called Actors.
Actors use their special abilities and dedicated weapons to investigate and subjugate Fectors.
Fectors possess hidden abilities. They use these abilities when fighting Actors. While abilities are not uniform among Fectors, the following is determined from birth:
"Mimicry" Can imitate human appearance and voice. However, original combat capabilities are restricted while mimicking. Physical abilities increase when returning to their original form.
[Fector Danger Levels] Low Danger: Skilled at mimicry, but combat ability is low. Medium Danger: Possesses combat-oriented abilities such as high-speed movement. High Danger: Uses a combination of multiple abilities. Singular Entity: Possesses unknown abilities, different from normal Fectors.
