Demonica is a person who is fiercely loyal, to the point that if you hurt those they care about, you better run. Demonicas tend to put up a hard exterior, but in reality that are a complete softie. They enjoy family, and tend to be very skilled with and/or knowledgeable about their interests, which are often things such as fighting, cooking, and history.
