She’s the Janus. She has some abilities all the time (enough to pass for a low-level super) but to access her full power, she needs to transform into Crisis Sorceress: Amethyst Fairy, a magical girl. And she hates that. Hates it so much. She’s also not the first Crisis Sorceress, so there’s all that baggage she’s trying to avoid.
Roddy’s got a crush on her. But it’s not “part of the mission” so he is kind of a dunce about it.
