Yenma

Greedy, manipulative, lustful, gluttonous. They're use to getting what they want - through whatever means necessary, using the emotions of "lesser" beings to their advantage. Usually, they use their shapeshifting abilities to make themselves look younger and / or sexually appealing to their victim, although prefer a small or thin frame. They're truly childish, often throwing temper tantrums if it becomes difficult to obtain their desires.
