Nanako Ueno

Nanako is a very private person who lacks the maturity of similarly private characters. Nanako charges into situations, sometimes recklessly. She is firm in her personal beliefs and will behave selfishly if upset, never considering the consequences of her words until it is too late.

In order to navigate through her route, the MC becomes as much Nanako’s caretaker as Kazue’s caretaker. While MC’s expectations are more straightforward when taking care of Kazue, they must navigate Nanako’s moody, childish behavior in order to repair the relationship between the sisters.
