I've been trying to watch the new GXP series. It's hard going - much like the later seasons of Tenchi Muyo. The main problem being it includes people/events from the novels and I keep having trouble following who/what they are talking about.
Anyway, my vote if for Mari Tomita from Air Gear. Despite being constantly being paranoid that men are going to molest her, she has a tendency to act very erotically.
