If you do down the mansion to the basement, into the room with the mirror you can talk to the demon commanders in, absorb one of the blue orb spirits and go up to Sophie for her to take, she doesn't. She just says to bring her more if you find them. This is  a problem because I can't leave the mansion without giving it to her. Sophie is the kitsune right? And how do I fix this?

wrong character, the one you want is the girl from the mansion quest either in the room on the left of the front door or in the old room of the worker ghost. The Kitsune needs the souls you get from the silver chest( at the time of writing only 3 so far)
