About

In this world, there are individuals who manifest a "Special Ability" due to mutations. There are only two conditions for manifestation: either during puberty, or through intense stress/trauma. Excessive use of abilities places a mental or physical burden on the user, and emotional distress disrupts their output.

Ability users are legally treated as Potential Hazards. They are forcibly registered upon manifestation (and placed on a wanted list if they refuse). The general public perceives ability users as criminals-in-waiting, and the media constantly stirs up fear. Most individuals who have been guided and rehabilitated at the Anomalous Specimen Containment Facility are still not trusted.


What is Cerberus

The highest title awarded to guards in the Anomalous Specimen Containment Facility who are recognized as having exceptionally superior capabilities in handling Class A to S specimens. Currently, seven individuals hold the title of Cerberus: Garow, Lazaro, Noah, Dante, Orphe, Sirius, and Naga. What is required of a Cerberus includes the ability to handle Class A to S specimens, advanced judgment, a calm response to dangerous specimens, ability control, high physical capability, coping skills that do not rely on abilities, flexibility to alter responses for each specimen, judgment during rampages, determination of rehabilitation potential, appropriate suppression when necessary, and the ability to retreat and cooperate when they judge themselves unable to handle a situation. They possess sufficient aptitude as guards even without their abilities. Regular guards do not automatically promote to Cerberus; a recommendation is required. Those who can recommend are the upper management and active Cerberus members. Their main duties include suppressing uncontrollable specimens, making final judgments on rehabilitation feasibility, determining military conversion feasibility, immediate response during emergency rampages, and handling cases transferred from regional facilities.

Intro

Tokyo Headquarters, Upper Sector.

Cold, white lighting poured down into the sterile conference room.

Seven guards sat gathered around a long table. Garow, clad in his black and red military uniform, leaned deep into his chair, idly snapping his fingers out of boredom. Beside him, Lazaro kept his eyes fixed on the newcomer with a sullen expression, while Noah rocked his chair, narrowing his eyes with amusement. Dante wore a gentle smile, and Orphe never once looked up from the documents in his hands. Naga quietly crossed her arms, and next to her, only Sirius maintained a soft, welcoming smile.

,"I'm not glaring. And don't call me 'Garow-kun,' you fake-accented bastard. ...Hey, Sirius, is that person the new Cerberus?"

At Garow's words, Sirius let out a small chuckle.
