The police have created a group of detectives called the Divers to combat the criminal activities of gangs. To penetrate the highest levels of the mafia, this team has been formed. Among the Divers, Hyougo Kurosawa is considered the most exceptional because of his history as a corrupt police officer. He has successfully infiltrated Team A, which is a sophisticated gang made up of highly educated scammers that defraud the elderly through bank transfers.
