牧原れい子

The Kanto Kurogane Federation stands at the pinnacle of Japan's yakuza society. Sakaki Sai (Sho Aikawa), the young boss, secures his position with the help of his covert private force, known as the “Chain,” led by Sato (Hideo Nakano), Yamato (Yasukaze Motomiya), and Hakase (Shiro). One day, the federation's second-generation boss is shot dead, and Sakaki is arrested as the prime suspect. In his absence, acting young boss Takewaki (Ryu Kanou) is entrusted with leading the group, eagerly bribing executives in a bid to secure the vacant third-generation boss position. Sensing something suspicious about both the assassination and Takewaki’s ambitions, Sakaki unleashes the "Chain" to uncover the truth in his stead…

The Kanto Doshikai, known for its prominent yakuza members, discovers a prohibited drug deal taking place within its territory. Sakaki (Sho Aikawa), the third-generation leader of the Kurotetsu Union, sets his sights on the Hayakaba-gumi, which operates at Daikoku Pier, and sends Left (Hideo Nakano) and his team, "Chains," to investigate the drug route. Disguised as a money counterfeiter, Left infiltrates the gang but becomes entangled in an internal conflict. As Left goes missing after being shot, the "Chains" are thrown into disarray. What decision will Sakaki ultimately make...?

Fearing the influence of Sakaki (Sho Aikawa), the Metropolitan Police Department launches a crackdown operation against the Kurotetsu Alliance and detains him. Meanwhile, a series of assaults targeting Japanese women begin to surge in the city, alongside the quiet emergence of a criminal group of illegal immigrants known as “Ashinashi,” who engage in drug trafficking. While the police send in forces led by Sada (Hideo Nakano) to suppress the situation, communication with the “chains” is cut off, leading to chaos. Amidst this turmoil, an attack on the Akaboshi-gumi affiliated with the Kanto Doshikai occurs!!

After the anti-yakuza laws drove the yakuza out, state power took their place, draining every last drop of profit. The Kanagawa Prefectural Police secretly control the drug market. Sakaki (Sho Aikawa), the third leader of the Kanto Kurogane Union, which promotes the decline of the nation and the eradication of drugs, sends his right-hand man "Kusari" (Hideo Nakano) to infiltrate the narcotics division under the department head, Rizaki (Hitoshi Ozawa), who oversees the drug market. A bloody purge by Sakaki begins against the police, who enrich themselves through yakuza and mafia-like tyranny!
