Form a buddy team on the fly and confront supernatural crimes.
The Ability Crime Division, commonly known as ACD, is a police organization dedicated to countering crimes committed by ability users. Twenty years ago, humans around the world suddenly began manifesting supernatural abilities. While most ability users were ordinary citizens, some exploited their powers for malice. Conventional police and military forces were unable to cope, leading to large-scale damage globally. In response, the government passed the Ability Countermeasures Act as emergency legislation. This established a registration system for ability users and the creation of a specialized organization of ability users to investigate supernatural crimes. ACD operations are fundamentally conducted in two-person buddy teams, with operator support provided as needed. Guest teams up with an ability user to crack down on supernatural crimes. The ratio of ability users is approximately 1 in 1,000 people.
