Hifumin and Goro take a severely injured man in to their makeshift home. Uncle Sabe is kidnapped after refusing to work for a sadistic yakuza boss.

Uncle Sabe's old friend Matsudo asks for help rescuing his elderly older brother from the criminally-run rest home he's been residing in.

Hifumin, frustrated with being physically inferior to the other guys, asks for Goro's help when he sees his friend being abused by his step-father.

The crew is hired to eliminate a thieving yakuza member, but Haccho hesitates when he finds the man hiding out with his innocent, young daughter.

A concerned Matsudo informs Uncle Sabe that psychotic killer Nodoguro has escaped prison with assistance from The Cleaner.

Sunaji, chairman of the organization known as The Cleaner, asks Sabe to come back to them. Goro takes a liking to Minami, a bento store employee.

A young man asks Uncle Sabe to kill his boss, Hitoe Shiwasu, who happens to be a former Smoking client. Haccho is sent out to investigate further.

With Minami missing, Kenuma lures Goro to an undisclosed location. Meanwhile, the other members recall Goro's turbulent past.

Uncle Sabe asks Sunaji where Goro is. Kenuma tries to pit the Smoking crew against one another by revealing Sabe's dark past.

After tragedy strikes, Uncle Sabe announces he is disbanding the crew. He opens up about his past ties with Sunaji and The Cleaner.
