The moment you look at this girl you should get a good feeling. She's cheery, fun, playful, always seems to have a bounce in her step and demeanor. Whether you're a person looking for merely a friend, or a corrupted fiend looking for a slave, she attracts some attention. Pretty, with an adorable innocence most crave, though not the type that is absurdly shy about things. She actually seems rather open and playful about everything. A simply purity, like she's rather happy with most of everything.
Her sexual behavior is just as playful, a little teasing, as if she simply enjoys it without reserve, obviously not caring the slightest bit about society's restrictions and taboos, or simply not understanding them.
The reason for her behavior is probably that she is descendent from a nymph, and that combined with a carefree attitude, it would be little surprise she is the way she is.
Anyone observing her combat style, it's as if she treats it like a game. Dodging, weaving, and striking, grinning the whole time, like she's playing with her foes. In her mind, she probably is.
In fact, it's rather difficult to think of anything that might actually anger or upset her, based on her behavior.

OOC: I kind of left physical description to the model appearance, since I was more focused on her personality in the biography.
My Red Lights are, as noted below, mainly for SRP. There are things that I might let happen with my characters that aren't entirely pleasant, just clear them with me first.

Green Lights:
Descriptiveness & Good RP (Including SRP)
Involved, long term RP (Encouraged! ^^)
Much, much more!

Red Lights (generally applicable only to SRP):
Anal (Of any kind, don't even mention it, or I'm gone)
Abuse (In SRP, including verbal, just doesn't mix with sex)
Bad/One line RP (Come on, make an effort, you might enjoy it!)
Bestiality (Self Explanatory)
Confusing my character with a restroom (seriously, two year olds understand that)
Freaky/Ridiculous Mixes (Keep your horse half breed hermaphrodite out of SRP)
Ridiculous proportions (2 foot penises or EE cup? Really?)
Permanency (You absolutely require my consent for that)
