The character "Agent" serves as the central protagonist in the "Riot Act 2 Special Movie" anime. Engineered by the powerful Agency organization as an ultimate battle machine, the Agent executes a mission to systematically eliminate criminal gangs overrunning Pacific City's futuristic metropolis.

Operating within the metropolis transformed into a hazardous warzone, the Agent navigates a three-way conflict.
