Cow Cow Finance is an unlicensed moneylending operation that offers loans at exorbitant interest rates of 50% over ten days. The company recruits Takada, a former host, as a new employee. Under the cold and ruthless leadership of its president, Kaoru Ushijima, Takada initially struggles with fear and unease. However, he gradually adapts to the harsh environment, working alongside senior employees to issue loans and collect debts. Every day, desperate individuals—people with no means to secure their next meal—flood the office, seeking financial relief. The story follows the relentless and often brutal world of underground finance, where both lenders and borrowers are trapped in a cycle of exploitation and survival.
