Leia's dad was an army Sargent with a taste for wine, women and song.  Lots of wine. He was a nasty drunk, and willing to teach his little girl, how to be a man. By age ten Leia was tough and angry. At age fourteen she was a monster… killing her father with one blow to the temple. So killing men has never been an issue for Leia. She's just accepted her next assignment to take out five members of the Cosa Nostra, and she is excited. It's an easy job for a beautiful sexual creature like Leia.
She enters the compound, posing as a hooker, and slides into her first victims lap. After a long petting session, Leia thrusts his face into her perfect healthy breast, cutting off his ability to breath. He fights to get frees but she's got an iron grip. He struggles until she snaps his neck. Leia is just getting warmed up. She continues deeper into the compound, and like a hot knife through butter, she kills each gangster with a variety of scissor legs, garrote and bare-handed strangulations.
