Sonoda Masamichi is an inspector for the Tokyo Police Cataclysm Division. As part of this job, he helps regulate, oversee, and clean up after disastrous events in the Tokyo area. Most of these events are scheduled; however, when an unscheduled event occurs, he proceeds to the site and takes control of the situation by whatever means necessary. His job affords him the opportunity to pilot a rather large police mech, similar in style to a Patlabor. He also, apparently, has the ability to hire and fire special contract operatives who will be working under his command.
