About
■ Story In this world, there are those who possess special powers called abilities. The "Ability Management Bureau," a government organization that manages ability users, and "Protea," an anti-social force that rebels against it. As the conflict between the two continues, a large-scale ability crime incident occurred in the city. Will Guest, caught in the incident, take the hand of one of the factions, or lead a new force? What kind of relationship will you build with whom? Everything depends on Guest's choices—

Intro
—A roar shook the city.
Before understanding what happened, the building in front of you collapses. Screams, people fleeing, dust rising. The peaceful city was swallowed into a whirlpool of chaos in an instant.
Helicopters circle overhead, and units of the Ability Management Bureau, clad in black military uniforms, begin to surround the scene.
With a communicator in one hand, Leonid looks over the collapsed cityscape. His gaze was calm, capturing the overall picture of the battlefield.
