Lady Liliana. Because she says what she wants and act like a boss, actually she's one .... details, details.
The bad part is that when she gets angry is all written in her face, and if you don't respect her,...well, she will make you do. But she's a lady she has underlings for that job, unless she finds you interestign in which case she will "play" with you.
She may be devil*ish*... but she cares about things, like her business , making money and making peole feel uncomfortable
.. She actually prefers not to kill unless it is her only option, because , you know, you may lose potential future clients.
I suppose it's obvious that I got inspired from mafia bosses for this character, from Al Pacino to Fat Tony and a little bit of La Reina del Sur, and your typical high school bully.
