Kenju burai-chō Nukiuchino Ryu
Zhang uses gardening sands he has in his pocket to escape the situation. Yang discovers an informant among the crew and orders the traitor to be found and eliminated. He also asks Ryuji and Colt to kill Hotta who had attacked his men when the partnership breaks off. Instead of complying, Ryuji demands that Fusae and Keikichi, tied up with Yang's drugs, be set free. Ryuji, who doesn't want to kill people, persuades Hotta to reconcile with Yang, but Gin reluctantly shoots him dead in the middle of it with his mistress, which leads Ryuji to punch Gin away. Yang sees Midori, the nightclub hostess, as a clue leading to the informant and tries to kidnap her to the office. Ryuji, who happened to be an acquaintance of Midori, lied, saying, "That's my sake. It has nothing to do with me." Before long, Midori's older brother, Ishii, a nightclub trumpet player, appears in front of Ryuji. Ishii was the one who passed the information on Yang Gang to the Hotta group and the Tokyo Police and revealed his identity as an undercover narcotics investigator working for the police on an illegal drug smuggling investigation. Knowing that Ryuji is saddened by Keikichi's drug addiction, Ishii asks Ryuji for help destroying the gang and stopping them from selling drugs to the American mafia who wanted to meet with Yang's crew at Yokohama. On the other hand, Yang decides that Fusae is the informant and tortures her, but Gin, who doesn't like Yang's methods of sadistic torture and cruelty, finds a chance and releases her. Keikichi, who is in the hospital, is also attacked by Yang's minions, but he fights off with punches, and Midori hides him while he is escaping.
