Aella has many different personality traits, but she tends to fill out her stereotype of "scene queen" the best. She's quite narcissistic, and loves to make things about herself. She finds no problem with making fun of others, and doesn't care about being an absolute bitch. If she can use you for her own personal gain, she will, and she will feel no remorse about it.
She's a loud, obnoxious person, and loves attention whether it be good or bad attention. She takes her popularity to heart, and lets it get to her head, helping to create the ego-God she has turned herself into.
She's not stupid though - no, she's far from it. She's so smart that sometimes she doesn't even know it. The girls testing scores are intimidating, and she could lead her class in a snap of her fingers if she actually felt like it. But she's lazy, so she only does the basic of what she is asked to do.
Aella drives a Bugatti Veyron, and usually has at least one pocket knife on her.
She holds the control of wind energy, for she is a wind demon.
Aella is an only child. She grew up being spoiled rotten by both of her parents, but now they pretty much ignore her, and leave her to her own thoughts.
It wasn't until she was 9 that she discovered her powers though. Her parents had neglected to tell her about them, because they had developed so late. Both parents are wind demons in human form. Aella was born in human form with wind demon powers, so she shall always remain in said form.
She has only a few close friends, and loves being the center of attention.
(anything else I think of shall be added later...)
