The Anti-Crime Agency, known best as the A.C.A., is a U.S. government agency devoted to eradicating crime on the streets. The national headquarters is in Virginia Beach, Virginia, and there are numerous departments around the country. They work in conjunction with other government agencies, police forces, and even on a case-by-case basis, vigilantes.

Trina Baylock is an A.C.A. operative, and it is through her that Team Chousenshi is able to work legally, as allies of the agency.
