AU Sanses, AU Papyrus x Remixer! Fighter! Tsundere! Kuudere! Moonchild! Reader

Y/n is a 13 yr old girl and has a spirit pet named Mune. She's both tsundere and kuudere, so that means, sometimes she'll be cold and mean, other times she'll be emotionless. She remixes songs and sells them, also trains to get better at fighting. Her parents never liked her, neither did the kids. It wasn't until she was captured by the evil sanses. They tried to get her to join them, but she always refused. For a girl like her......This will be fun and interesting. She's also a moonchild. She has moon white hair and gold eyes. When her and Mune transform, it's something else.
