In order to investigate crimes using a state-of-the-art surveillance system, the Kanagawa Prefectural Police Department formed a new Special Force named KSBC (Kanagawa Prefectural Police Department Investigation Analysis Center). Kyosuke Fushimi, who used to be celebrated as a brilliant detective at the Kanagawa Prefectural Police Department's Homicide Division, joins KSBC to try and solve difficult crimes shrouded in mystery. Fushimi forms a team of private investigators that includes quite some characters, like a former university professor of criminal psychology who is an expert at profiling, a single mother and former member of the Self Defense Forces, and a young genius hacker. At first glance, KSBC seems like a dream team, but it turns out that everyone is an "ex-criminal" with a dark past. From a "surveillance tower" equipped with cutting-edge technology, the investigators track down the culprits in real time.
