Lets see... Usagi is just too naive, though she's shown she has a wandering eye for Motoki or handsome women she thinks are men. She comes from a good, upper-middle class family, so she could easily have pent up sexual frustrations, especially when Mamoru takes time away from her to allow her to study which she refuses to do. Secret Skank level, 7/10
Ami is left unsupervised a lot, but seems way too shy to go looking for trouble, and her bookish tendencies make her a bit of an outcast. On the other hand, I bet she spends a lot of time left alone with her teachers, learning anatomy for her medical studies.... SSL, 6/10
Rei I've never liked and have a hard time analyzing. I don't know what her religion has to say on promiscuity, and it is easy to question if she even likes guys. Of course, lesbians can be skanks too. I could see her wanting to go out and let loose from time to time with whatever her orientation prefers. SSL, 5/10
Makoto, now we're getting somewhere. This girl has lived on her own since she was a loli, is lonely, and needs to make money to support herself unless she has some kind of inheritance or benefactor. She's very gifted physically and can defend herself if a illicit deal should go awry. SSL, 8/10
Mina (disclaimer, my favorite) is a girl that loves to party, wants to network and make herself famous. I'm sure she isn't above spending some time on her knees to fulfill her dreams, or even if she thought it could mean love for her. I wouldn't put it past her to confuse getting laid with being loved, which she very much wants. If she believed she was cursed by Kaitou Ace, she may even throw herself in situations where she gives up her body. Her only reservation would be ruining her reputation should she ever become a star. Aliases may help that, but how many busty blondes are there in Tokyo? SSL: 10/10
Haruka likes to play the field, but as more of a top. Much more of a pimp or playgirl than a skank. SSL: 3/10
Michiru, here is some serious secret skank. I really think she is bi, and could easily play around on Haruka. I think she likes being center of attention, and all that class and refinement makes her all the likely to be the center of a bukkake party or host to a high class orgy. In my mind, the fact she is is an artist both of music and painting space whales makes her likely to do whatever it takes for inspiration or to get her creative juices flowing. SSL: 9/10
Setsuna spends a lot of time alone at that time gate.... I see her thinking about getting laid during a lot of that time, and if she has her secret crush on Mamoru, that'd make her all the more frustrated if she came to terms with never having him. Even if she didn't, she might skank it up a little around him in hopes of an affair. Maybe if she ever got on top of him she might want him to knock her up to mess up his relationship? Maybe I'm reading too much into this? Maybe that's the point of this thread! Does she have a fashion line or am I confusing the cannon with a RP I do? If she does, she'd be adept in skanky fashion. I would say something about her skin shade, but don't want to be flamed.
