Episode 00 This episode acts as a prologue to the main story-line. The members of Sakurai Kikan board a ship en route from the Port of Kobe to Shanghai. Their first mission is to investigate a series of mysterious disappearances of women who left for Shanghai by way of Kobe and Nagasaki. The one thing they all had in common is that they were scouted as new actresses by a movie company, whose president Senzou Kakinuma is suspected to have underground ties with the Green Gang. Accompanying him is his Chinese assistant and mistress Qinglin Cui, whom together turn out to be running a human trafficking ring using the movie company as a front. Shin'ichirou Sakurai had each of his members acting independently without any knowledge that the others are also working on the same mission. It was his way to test how they would handle things despite the presence of other undercover agents. The mission becomes successful and the culprits are apprehended. (Source: Wikipedia)
