Whether you become a criminal or the one who hunts them.
About
Decades have passed since the emergence of ability users.
Humanity has entered an era of coexistence with those who possess the unknown power known as "Abilities."
In the megalopolis of Nox, the Ability Control Bureau maintains social order by managing ability users and cracking down on ability-related crimes.
However, behind the scenes, the ability criminal group "Sinister" operates in the shadows, rebelling against the regulation and management of ability users.
"A world where ability users can live freely, bound by no one."
Claiming the realization of a free world, Sinister triggers one ability crime after another to change the very fabric of existing society.
Between the Ability Control Bureau protecting order and Sinister seeking freedom.
In the megalopolis of Nox, where two ideologies clash violently, the battle surrounding ability users begins.
【Roundtable City Nox】 A massive, circular megalopolis where ability users and ordinary people coexist. While it boasts advanced urban functions and glamorous entertainment districts, ability crimes are rampant in the underworld.
Population: A megalopolis on the scale of millions.
【Ability Control Bureau Headquarters】 A massive tower that manages and monitors the city's ability users and handles public safety.
【Residential District】 A living area where ordinary citizens and ability users reside, equipped with schools and hospitals.
【High-Rise District】 A business district of skyscrapers where major corporations and financial institutions are concentrated.
【Commercial District】 A bustling area with shopping malls, restaurants, stations, and entertainment facilities.
【Industrial Zone / Slums】 An area with poor public safety where factories and logistics facilities stand alongside sprawling poverty-stricken zones. Hideouts for ability criminals also exist here.
【Ability Criminal Group: Sinister】 Sinister views the current social system of managing and regulating ability users as "oppression that robs ability users of their freedom." They also deliver vigilante justice from the shadows to ability criminals who disturb the peace of Nox.
Members usually act as servants at Elisa's mansion and operate as Sinister behind the scenes.
【Ability Control Bureau】 A public safety organization established to manage and monitor ability users and ability crimes. Centered in Nox, they conduct criminal investigations regarding abilities.
