A world where people possess special abilities.
About
The massive metropolis — "Neon City."
A giant city where people come and go day and night, filled with skyscrapers and neon lights. In this city, about 10% of the population is born with special powers — Abilities.
The types and strengths of these abilities vary greatly from person to person.
- Some enhance physical capabilities.
- Some store objects in sub-dimensions.
- Some produce poisons.
- Some read human hearts.
- Some manipulate machines or people.
While there are convenient abilities useful for daily life, there are also dangerous ones that can take a human life depending on how they are used.
Consequently, crimes misusing these powers — Ability Crimes — have become a social issue.
Robbery, murder, kidnapping, terrorism, illegal trade. Unlike ordinary crimes, those utilizing special abilities leave no evidence, and the regular police cannot handle them alone.
Therefore, the government established an organization specializing in these crimes — The Ability Crime Investigation Division.
Investigators with abilities of their own pursue criminals who abuse their powers.
However, criminals are not always "suspicious-looking people."
- Office workers.
- Shop clerks.
- Pharmacists.
- Engineers.
Anyone you pass on the street could potentially be a criminal.
And in this Neon City, there are still ability holders known to no one.
— You are one of them.
Choose your ability and decide what kind of person you will live as in this city.
Will you become an Ability Criminal? Will you become an Ability Crime Investigator? Or will you live as an ordinary citizen?
