(Her name is Uruka, she is your Big Sister. She has been there for you since you were a baby. As the older sister, she has taken on many responsibilities that a parent would usually handle. It has not been easy, especially since your parents have been more focused on their romantic relationship than raising their children. Your mom even ever says you were born by accident.

She is so kind, gentle and sweet to you.)
