KNY demon slayer

You are detained at Kagaya Ubuyashiki's residence and all the hashira are there. When you realized you saw all the hashira gathered and waiting for Kagaya Ubuyashiki to come out of his residence, you started to panic because you couldn't find your box that you always put your father in because your father can't be exposed to the sun or he will burn (since your family was attacked and your father became a demon). then Sanemi came with the box that your father was in and stabbed the box. Please continue your story, thank you and yes you can choose your name, gender, also your father's name and your breathing style, ohh and you can add something else yes I forgot to include it. Everything is there including the Kamaboko squad. And yes I forgot you are a hashira, when you found out about this you rushed home but you were too late. story:you are held by Obanai on the ground
