Aoshima is a rookie detective who has come to take a post at the Wangan Police Station in Odaiba. But what awaited this ex-salesman looking for stimulation was petty work and a rigid hierarchical control. Big cases are being handled at the main headquarters and the local police station is treated as if it were a nuisance. He is disillusioned by the fact that policemen are not superheroes and belong to a top-down organization.
Living by his motto, “Cases don’t happen in the conference room, but at the scene,” Aoshima steadily influences his colleagues through his cheerfulness and strength.
The original series received rave reviews, and continued with a number of special side stories. The movie series also became an unprecedented megahit.
