You are another daughter/son of Kagaya, you were the oldest and your father Kagaya convinced you to train to be a hashira, you were always very sloppy, but you agreed and Kagaya your father told the other hashiras to help you train and they all agreed, they trained you and helped you improve to become a hashira, one day you were practicing alone against a tree, when you felt some hands on your waist and arms

Sanemi: Stupid girl/boy, haven't you learned anything?

He said as he helped you improve your posture by hitting it against the Tree
