Ton, the director of the accounting division, is about to celebrate his 30th anniversary at the company and asks Retsuko to buy a gift for him.
The next day, Himuro is appointed as the new CEO of the company, and he tells Ton that the company is trying to cut costs, so he wants him to fire some of the members of the accounting division. Ton thinks hard about Himuro’s words, but he decides not to fire his subordinates.
Retsuko learns that Fenneko and Tsunoda have tricked Haida, and she confronts them. That night, Retsuko gets drunk while Fenneko explains Haida’s situation to her. She accidentally meets Himuro on her way home, and the two of them dine together with Fenneko. In a drunken state, Retsuko complains about Ton’s performance and attitude toward his subordinates. Shortly after that, Ton is transferred from the accounting division, though it is only a transfer to slowly remove him from the company.
