Miko's been in this business a long time. She doesn't have more than another decade left.
1 million yen upfront can be invested and will make considerable and stable returns.
For the first few years, Miko will make more money per anum, but once she graduates, the million will continue to make you costless returns while Miko will cost you food, water and electricity while her value steadily depreciates.
