Ushijima runs Kaukau Fiance, a black market lending agency which scourges its clients with interest rates as high as 50% for 10 days. Ushijima chases down his debtors, who normally come from the bottom of society, with ruthless efficacy.

Sawamura, a contract part-timer dragged into a multi-million yen internet business, and Kamo, an office worker who lavished money on a beautiful club hostess, arrive at Cowcow Finance, the office of black-market lender Ushijima.

A classmate from Ushijima's middle school days, Takemoto, shows up. He was a kind man, but now is jobless and without a home. Adrift and unable to borrow money from Ushijima, Takemoto heads for Seiai Home where he can stay while doing work.

Mirai Suzuki (Yuko Oshima) becomes responsible for her mother's debt which is owed to loan shark Kaoru Ushijima (Takayuki Yamada). To begin paying off her mother's debt, Mirai begins working at a dating cafe. Meanwhile, Jun (Kento Hayashi) is the ambitious and greedy company president for an event group. To borrow money, Jun visits Kaukau Finance owned by Kaoru Ushijima.

To pay off his loan shark, failed actor Ryōsuke Kinuta is forced to smuggle dead bodies – and one live elite assassin – in the middle of the night.

Kujo (Yuya Yagira) continues to live under a tent on a building rooftop, taking on anyone who seeks his help, including those from the criminal underworld. Although they have separate ways, Kujo's former partner, Karasuma (Hokuto Matsumura), is drawn back into his life as the two become caught between a violent underworld conflict and an escalating police and prosecutorial crackdown.

Kaoru Ushijima's Kaukau Finance is the lender of last resort for many of the poorest people in the area: He collects without mercy and without fail.

From thugs to yakuza, Taiza Kujo wields the law to defend society's worst. Fellow lawyer, Karasuma doubts his ethics but joins him in facing the abyss.
