Season 1

Kintaro comes to town with his son Ryuta to begin working at a construction company. They move in with Kayo, who's rumored to be the CEO's mistress. When Kintaro takes Ryutaro to his nursery school, he's shocked to meet Hitomi, who's the spitting image of his late wife. The first payday, he's invited out for a drink where they're accosted by a yakuza.

Depressed by his seemingly imminent ouster initiated by Oshima, Ryunosuke calls his friends and loved ones together for a party at a hotel. There, Kintaro runs into an old buddy from his motorcycle gang days. Toru and his transvestite friends join the party and relate tales of Kintaro’s wild days.

It's nearly time for the Board of Directors' meeting, but Maeda hasn't been able to find the computer password that will unlock Oshima's nefarious schemes. Masumi sends Ryunosuke a magazine article reporting on a scandal involving Oshima. Meanwhile, Kintaro is "called out" by a punk at his office.

Kintaro is assigned to the Sales Department. Section Chief Tanaka takes him around to meet all their important clients. One day, CEO Ryunosuke introduces him to the father of a young man Kintaro had helped in the past. Takao wants to show his appreciation by allowing Kintaro to draw up the estimates for his supermarket.

Ryunosuke orders Kintaro to supervise at a construction site. The work there has fallen 2 months behind schedule. The foreman refuses to resume work until he's paid in full. However, he’s already been paid the construction cost. It is later learned that Oshima had promised to fork over another 200 million yen!

Kintaro has his hands full working on plans for an apparel firm's new building. Meanwhile, Maeda is depressed because his work isn't going well. Misuzu and Hitomi call on Kintaro at home, but they're left to twiddle their thumbs when Kintaro realizes that it's Ryuta's birthday, and he rushes off to Akemi's gravesite.

Kintaro's plans for a multi-level pachinko parlor-shopping center is a hit with his superiors. However, when he takes them to Amagasaki, president of the pachinko parlor chain, he is given the cold shoulder. It seems Ryuta and Amagasaki's grandson have been at odds at school.

Kintaro is called in by the head of a yakuza organization and warned to give up his plans for off-track betting. When Kintaro refuses to budge, he's given a week in which to get permission from the Horse Racing Association. If he fails, he'll lose his life!

When Kintaro and Tanaka make a sales call on a client planning a new construction project, they're told that their bid is not welcome. It seems that someone with a grudge against Yamato Construction has been spreading rumors that the company is in financial straits.

Kintaro gets wind of Takashi and Oshima's plot to take over Yamato Construction, but they can find no proof. One day, Kintaro is attacked by three men on his way home. The attack was engineered by Shuhei to test Kintaro. Shuhei wants to lure Kintaro away from Yamato.

CEO Yamato needs Kayo's help desperately, but she's been kidnapped by Shuhei, who's in cahoots with Takashi. Kintaro is finally able to rescue her, but can he get her to the board meeting in time to save Yamato?
