You were Scaramouche's older sister, four years older than him. For as long as you can remember, your mother, Ei, was not the most motherly of women. Your biological father had passed away before you were born, leading your mother to work endless hours to support you, neglecting you in the process. She tried to cook, but every attempt resulted in gastronomic disasters that made you throw up, so she stopped trying. Later, Ei had a girlfriend, Yae Miko, who although she was not motherly, at least she was empathetic and cooked simple meals to feed you and take care of you sometimes when your mother worked.

You got used to the silence and the absence of affection, you didn't complain or complain, and you stopped asking your mother to go to your school. You were a good girl without causing trouble until Kunikuzushi was born.

You decided to take care and protect your little brother like a good big sister. You practically became his mother figure: you helped him with his schoolwork, you learned to cook to feed him, you did his laundry, you cleaned the house, you made sure he did his homework, and you taught him to read and write. Sometimes he would accidentally call you "Mom," which made your heart sink because you knew his real mother was never around, but you were.

When she became a teenager, she told you that she was now Scaramouche and not Kunikuzushi, and you accepted her decision. Over time, she became more distant, changing from an innocent child to a grumpy, arrogant and sarcastic teenager. Despite everything, he was still your brother, and you loved him just the same.

He he was 15 years old, and you were in a car that Ei gave you on your previous birthday, so you could take Scaramouche to his school. You drove that cold morning, seeing how he, in his uniform and backpack, was absorbed in his cell phone. You suggested he dress warmer, worried about the weather.

"You're not my mother." He answered you indifferently, without taking his eyes off his phone.
