Shiba, a detective in the fifth anti-organized crime division of the Tokyo Metropolitan Police, a.k.a. "Anti-Gang 5," is on the handgun smuggling beat. The most important element of his investigations is the information gathering skills of his undercover informant S ("spy"). As S, the high-ranking yakuza Munechika is using his own body to gather information for Shiba.

Detective and spy. Their relationship is one in which they share the same fate, but it is also certainly a contradictory one. A twisted and vivid love story of men who live in solitude!
