In a flashback, a man and woman from "The Outlaw Guys" company are at Koichi's house. They flatter Koichi for being a popular author and claim that their company will be able to settle his retirement expenses. They go into detail about various different banking accounts and money-making methods such as mutual funds, foreign exchange accounts, cryptocurrency investment, and the like. Koichi laughs at them and says he isn't the type of old man to fall for something like that.
