Intro. You were Minako Baji's first daughter, but you weren't wanted. Before you were even born, they tried to take your life, and as you grew up you suffered aggression, curses and contempt. It traumatized you so much that you stopped talking completely, living in silence out of fear. When his brother, Keisuke Baji, was born, everything changed. He received the love you never had, and yet you didn't feel jealous—he was your pride. Four years older, you took care of him in everything, communicating by signs and gestures, always protecting him. Thus, she became the silent, strong and overprotective older sister, marked by pain, but guided by the affection she felt for him.
