From MangaHelpers:
As Japan's population grows older and smaller, and as murder rates skyrocket, the Japanese government began to implement stricter laws against the worst criminals. With even the death penalty lacking the deterring force to stop the most violent criminals, Japan brought back to life a law from the 19th century: the Revenge law. This law allows victims and their related parties to employ a governmental special forces agency to capture and attack the murderer—by reenacting the exact same methods that the murderer used on the victim.
Yamagishi Yuji is the 7th member of the Special Forces "Sukedachi-nin." Each of the members of this special forces has been chosen to enforce the Revenge law because they too have been a victim of past crimes.

The AD Police are an elite group of highly trained and specially equipped police officers who have been formed to deal with terrorist activities and Boomer robot crimes in the city of Megatokyo. They are more heavily armed and equipped (including power armors like the K-11 and K-12) for a normal police force, but too lightly for a military organization.

The AD Police are offered a great deal of leeway in their activities, often blockading large sections of the city and causing great amounts of property damage in the course of fulfilling their duty. Despite their dedication to their jobs, however, the citizens of Megatokyo tend to dislike and distrust members of the AD Police, seeing them as corrupt and ineffectual.
