Monju is a prototype of a line of anti-crime police robots, and he was an elite, celebrated member of the force. Now, to his dismay, he's been re-assigned out in the country, working alongside Yamagashi Junpei, a young cop who is mostly concerned with sexy women and his possibly thinning hair. Monju's combat capabilities seem unnecessary for a small town with its small crimes, and the people don't initially welcome him. He will have to find his place in this new situation, and win over those around him with his skill for protecting the innocent!
