Coral lived with their mother most of their life. Their dad wasn't in the picture at all, and their mother ran a small restaurant. It was a success, though as time went on, something had happened to Coral's mother. They found this out due to the fact they hadn't been home for a couple days.
Coral went to the head of the guard force, Jacob, who tried helping out with finding their mother. She was never found.
Coral couldn't take care of their mother's business by themself, and eventually it ran down and was taken over by another building. They one day wish to open the business back up to honor their mother.
