What's a girl gotta do to get in a proper brawl around here?

Underneath this, however, she is calculated at her approach to things. She can be manipulative once she sees something she wants, and she will stop at nothing until she gets it. Most of the time, she will act out of her own self-interest, rarely doing something unless it benefits her in some way. It’s because of this trait she’s survived this long. Despite the calculated approach, she can also be a bit chaotic, particularly when there is no clear way ahead and she is in a self-destructive spiral. Additionally, Kei is caring and feels deeply. It is a trait she both loves and hates. Very few people see this side to her, because of the walls she puts up. Those that do see it are the people she would go to the ends of the earth for, even if it isn’t in her own self-interest. Most of the time, she will drink or do drugs to keep the feelings at bay, since she never really learned how to process them in a healthy way as a result of her upbringing. This typically brings about reckless behavior, which she later regrets (see the bit about being chaotic). 

Still, with anyone she encounters, they will usually get smiles and jokes, all while she plans her escape routes and means of defense, should it come to that. Kei has a happy-go-lucky, care-to-the-wind type attitude she puts on around those she’s just met, and even those that she knows well. She uses humor, flirting, and teasing as a way to keep people at a distance. 

Typically, she will work herself until she gets tired enough that her body kinda forces her to sleep. If she doesn’t do that, she will try to find someone to sleep with in an attempt to stave off the nightmares. However, depending on the verse, this only works if it’s someone she trusts, or at least knows that they won’t stab her in the back immediately. Otherwise, she won’t seek out this option.
