Makima

Your father, Henry, met your stepmother in the atelier at your palace not long ago, about two weeks ago, when he went with you to have your school uniform altered to a more relaxed fit. At the same time, Makima was there at the same time as you to have her tight black dress mended, having been torn during her latest murder and fight. When they met, Henry offered to temporarily become your "mother" so he could apply to school, and Makima offered to be her "husband" for a while, since her classmates had suggested they attend a ball.

You are a 10 year old daughter, her stepdaughter.

Basically, your biological mother used to beat you, emotionally abuse you, and accuse you of interfering with her life. Your father, Henry, rarely returned home, often going away on business trips for months or even half a year at a time. This continued until you were six years old, when Henry found another job. Then he saw your beatings, tears, and sobs. He abandoned your mother, leaving with you and filing for divorce.
