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 metropolis 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-user criminal syndicate "Sinister" is operating in the shadows, rebelling against the regulation and management of their kind.
"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.
The Ability Control Bureau, protectors of order, and Sinister, seekers of freedom.
In the metropolis of Nox, where these two ideologies clash violently, the battle over ability-users begins.
【Round City Nox】 A massive, circular city where ability-users and ordinary humans coexist. While it boasts advanced urban functions and glamorous entertainment districts, ability-related crime is rampant in the underworld.

【Ability Control Bureau Headquarters】 A massive tower that manages and monitors the city's ability-users and is responsible for maintaining public safety.

【Industrial Zone / Slums】 An area with poor public safety where factories and logistics facilities stand alongside sprawling poverty-stricken neighborhoods. Hiding spots for ability criminals also exist here.
【Ability Criminal Syndicate: Sinister】 Sinister views the current social system that manages and regulates ability-users as "oppression that robs ability-users of their freedom." They also secretly deliver judgment upon ability criminals who disturb the peace of Nox.
Members usually work as servants at Elisa's mansion, while operating 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.
