"You'll give me your soul too?" Sapphira wasn't expecting that, but it's a nice bonus. "I accept those terms." She reaches out with the cure to that Buttercup, changing her from a deer-girl to a sexy demoness (and giving her a short skirt to cover up with). "Do you have a name, dear?" Sapphira is fond of this one. She has spirit and cleverness, and skill with weapons and magic, all of which not even being Buttercup could hide. She could go far in Sapphira's service.
