Scarlett has only ever wanted to just stop, to breathe, and to look at the good things in life. Sadly, life hasn't given her any of this. Time after time she has run from her bloodthirsty family and has hidden in the dryest plains in the world. Her brother, her two best friends, and Ikaros her falcon who's been with her since birth are all helping each other run from their problems.
Kai, one of Scarlett's brothers, has been running with his sister from many obstacles that should've killed them by now. He is still surprised it hasn't killed him yet either. But he supposes that's what happens when your crazy family trains you to be the best killer, fighter, and crazy smart genius who can remember everything he reads. Obviously he isn't unstoppable but it's sure as hell hard to fight him in close combat.
Rose, old time best friend of Kai's who would most certainly take a bullet for him, is running from her father. Her old man is one of the top tier mercenaries in the world and he seems dead set on killing her. Why? No idea, she's pretty sure the bloodlust just got to his head. Now she's been running in a group with Kai, Scarlett, Sara, and herself as a group of killing machines. Whatever you want to call them either way she's definitely killed some people too. She's not that different from her father.
Sara, knows Scarlett like the back of her hand like the fifteen languages she can speak. Honestly, she doesn't have family issues like everyone else here ( I mean how can you when you've never had a family to begin with?). So she's stuck with one genius who's hell bent on destroying their enemies (Kai), one assassin/hacker who can never get caught but is reckless and despite her high IQ pretty stupid sometimes (Scarlett), and one unstable killer who acts if the world can't touch them despite having emotional attachment issues (Rose). Honestly, she's pretty sure she's the only normal one in this group.
