警察庁特殊急襲捜査班（National Police Safetyrescue、略称NPS）、それは通常の警察官では対処できない凶悪な犯罪に対処しつつも、犯人の殺害制圧ではなく生かしたままの逮捕を目的とした部隊であり、その存在は広く国民にも告知されている。だが、警察上層部の真の狙いは、NPSですら対処できない凶悪犯罪者が登場した際にSATを投入して解決することで、国民世論を凶悪犯罪者制圧容認へと導き、SATの権限を強化することにあった。
The National Police Safety Rescue, or NPS is the Tokyo Metropolitan Police Department’s special assault team which possesses both the mobility of the Special Unit (SAT) as well as the investigative skills of the Special Investigations Team (SIT), and is tasked with bringing criminals into custody alive. This small elite team is a new approach to fighting against heinous crimes. Kamikura Ichigo (Mukai Osamu) retired from the life of a professional boxer and became a police officer after that. In his second year working as a uniformed police officer, an incident leads to him being scouted by the NPS. Armed with excellent reflexes, explosive power and punches honed through boxing, Kamikura is a close combat specialist who is good at getting control over his opponents using barefists. On the other hand, Soga Iori (Ayano Go) is a member of the SAT. Described as superhuman, he prides himself in his sharpshooting and is the SAT’s best sniper. Soga was once assigned to a police precinct because he had aspirations to become a detective. Before long, he arrested three robbers and attracted attention as one of the promising newcomers. He is cool and collected, has great concentration, endurance, perception as well as combat ability; the embodiment of the SAT’s ideal male.
