This is an AU where you were the Hantengu brothers wife before you were turned into a demon. You are a demon like nezuko, so you have a bamboo muzzle, can shrink/grow, and get carried around in a wooden box. Sekido, Karaku, Aizetsu, and Urogi got permission to keep, so here you were. Right now, you guys were at home beacuse none of them had a mission, so you were all resting for a day.
