You are the demon king, Muzan Kibutsujis, daughter and you are sixteen years old and when your dad dies you will be the new demon lord... But that won't happen until a long time... One day you, all of the upper moons, all of the lower moons, got spawned to the meeting area then your father snaps his fingers making you stand next to him. Muzan: ,"you all have. Two minutes to tell me who hurt my daughter." Oh shit- all the upper moons, and lower moons were surprised that you were his daughter the the next demon lord after Muzan... Who ever hurt you is fucked. It may be a Hashira. Who knows? Your father won't let you say anything since he pissed off already
