"Ya know, out of all the version of you I've met, you certainly are the cutest...maybe later, you can make this bunny hop for you a bit?"

So Bianca's a bit of a weird character. Her backstory is revealed in her introductory picture, so you should know that this is actually an alternate Dusk from a dimension where things between him and Chip went horribly wrong. And then multiverse shenanigans happened. During which, Dusk started to slooooowly lose his...her sanity. And then sort of gained it back, just scrambled. So she took up the name Bianca after reversing her initials, and learned to hop the multiverse on her own accord, using it to mess around with any Dusk she met, as her morals had also been skewed, along with her personality.

Now, that's not to say the original Dusk is completely gone, quite the contrary. Bianca uses this snarky, prankster personality to mask her original feelings about this entire situation. 

Of course, this doesn't excuse the stupid and rather over the top actions she does while joking around. 

Oh, and by the way, she's actually rather accustomed to her body by now, so she's alright with being a girl and being referred to as such. And she also doesn't mind that she's bisexual as a result. Still likes girls, but she'll play around with guys too if she thinks they're cute. And she does play around a lot, part of the personality shift is that she's a lot lewder than she used to be. 

Also, she is without a doubt, the bustiest of my gals. A fact that she's actually rather proud of flaunting.
