Self-Inflicted Anchromatic

Muzan takes in a young girl who blames herself for all that has happened to her, not giving it a second thought. She's damaged. She doesn't know how to be fixed. She can't help it when she does it. She's determined on finding a way to die. A way to repent for her sins. She has so many scars. So much hurt. The demons do their best to make her happy, but can't seem to do it.
