The Shadow Sisters

I present...the Shadow Sisters! I'll introduce.<br />
<br />
Karen is the oldest and the most popular among her friends at the witch school she and her sisters dropped out of. Being the boss, she likes to order her sisters around, especially Krystal.<br />
<br />
Kristen<br />
The tough one, Kristen struggles with fitting in, and feels as if Karen can't understand her. She is nice to Krystal, but often hides her kindness when Karen is present.<br />
<br />
Krystal<br />
The girly-girl and the youngest, she often gets on older sister Karen's nerves. Her magic is pretty good, though.<br />
<br />
So...do they remind you of anyone? Anyway, please comment!
