In a future Tokyo, the criminal use of industrial construction robots has caused the police to recruit mobile robot divisions to combat robot crimes.
This is the story of Noa, and her police team mates who joined the newly formed division, piloting the advanced 98 model AV Ingram robots.
I think this is a good series, combining robots, police, and intrigues together. Notice the number of volumes: 22! This is a very popular work that has a number of anime movies and videos published.
