志水李里子

Receiving a request from a marriage broker operating in a run-down area, Hidari (Hideo Nakano) and Yamato (Yasukaze Motomiya) find themselves helping with a fake marriage. Many of this broker's cases involve the Goroza family, who are involved in human trafficking and insurance fraud, manipulating household registries. Amidst this, Yamato's fake bride, Shirayuki, is brutally murdered after having her organs harvested. Angered by this heinous act, Left and Yamato, without any directive from the third-generation leader of the Kurotetsu Alliance, Sakaki (Sho Aikawa), take on a rival gang. Thus begins a bloody purge driven solely by their unbacked "chains."

The 5 billion yen drug operation ended in failure due to a trap set by the Tomoe family. As Riasaki (Hitoshi Ozawa) and Hidari (Hideo Nakano) investigate the truth behind the situation, they finally encounter a man named Igarashi, who has just returned from China. While Riasaki weakens under the pressure from within the police and threats from the Chinese mafia, the blood purge from Sakaki (Sho Aikawa), the third chairman of the Kanto Black Iron Alliance, is carried out.
