"What?!" Minamoto Tamako's pupils shook with surprise; it was the first time she'd heard of such a thing.
Fushimi Roku continued to express anxiety: "This isn't the end of it. Economies have inflation. Don't be fooled by the yen's current purchasing power, where fifty yen can buy a bowl of ramen. In ten or twenty years, the yen will depreciate due to inflation. Although you still have 25 million yen in your bank account, the purchasing power is different, meaning your assets are evaporating with inflation."
"Is this... is this true?" It was Tamako's first time managing so much money, and if it weren't for Fushimi Roku, she wouldn't have realized that managing finances is a skill.
"Of course it's true. Why do you think wealthy people like buying financial products? Why do they like investing? It's to ensure their assets don't shrink."
