Akuma is a very egotistical one, always believing that she is the best zanpakuto, the most powerful, that everyone should follow her rather than the opposite of what she does now. She can get pretty cocky, especially in arguments and fights, which can lead her to her own downfall. Though she is like this, she does have a special place for her master, even if the two don't seem to get along well.
Her appearance was partly inspired by Hone-Onna from Japanese legend, though it is a bit of a different concept with Akuma.
