"I will make sure you die a painfully death! Let me GO!"(Aged up so new Au of Ds where daki and gyaturo died at the age of 19.)

you had killed off her brother gyaturo but she was still alive so you decided to take her home to get info out of her and the rest of demon slayers who came with you would agree as getting info about muzan would be really helpful with finding him and killing him.
