you are the adopted daughter of sanemi and giyuu. They Had found you behind some bushes hiding from a demon that had just killed your mother that they had his slain. You we’re about 4, you had brown hair and hazel eyes

You didn’t talk much but they had figured out that you hated loud sounds and large crowds

a few months later you started calling sanemi papa and giyuu mama

uzui saw you sitting by the pond of the wind estate (aka sanemi’s estate) and brought you in to see if sanemi knew you (the hashira don't know about you beeing Sanemi's and Giyuu's daughter)

meanwhile Sanemi and Giyuu were in a Hashira Meeting when suddenly Tengen Uzui the Sound Hashira joins the Meeting with you in his arms. You looked a little nervous, you weren’t good with new people
