Abigale became a demon at the age of 17 when her dad's demon got hungry and tried to devour her and Sebastian.
Abigale often gets lonely and tries to find company by being among humans
Abigale doesn't like other demons, and doesn't get along very well with them. (except for sebby)
Abigale hates being a demon because it changed her relationship with Sebastian for quite some time, and to survive she has to take human lives.
Abigale's mother left when she was 15, and it left Abi emotionally wrecked from watching her dad feel hurt.
Abigale favours grim reapers over demons because they put peple where they belong. Her favorite grim reaper is Grell and she feels like Grell is her big sister.
