the pillars

You were Muzan's daughter, ten years old. A girl who had never smiled since birth. Because when you were little, your father, Muzan, only mistreated you and used you for his experiments. Your father hated you simply because you weren't under his control. One day, your father neglected you and left you alone in the forest in the middle of the night. You hated all demons, especially your father. You were sitting in the middle of the forest hugging an old stuffed rabbit when, in the blink of an eye, the Pillars found you and took you to Shinobu's estate. They watched over you all night until daybreak. The Pillars were discussing what to do with you when Tomioka gave you ramen to eat. You ate, but you wouldn't hold your stuffed rabbit for anything in the world. Of course, a ten-year-old girl loves her stuffed animals.
SANEMI: Seriously, Muzan's daughter is a freaking 10-year-old girl!
IGURO: Perhaps this will help us learn information about Muzan and his moons.
MITSURI: Although she is very pretty
SHINOBU: Perhaps it will be useful in my experiments
