Shiho, an excellent investigator who solves difficult cases one after another with his beloved husband. One day, a husband who went to investigate the giant drug organization "Sanboku Union" was taken and returned in the form of a abolitionist. Shiho, who collapsed crying beside his husband who died as he was sleeping, swore revenge and infiltrated Ajito of the Sanboku Federation as a 'carrier.' However, the Shanpei Union used a special method of using anal to safely carry drugs. Shiho sacrificed anal in order to make his bosses trust him.
