Not a little girl but a killer

I am a as assassin. My family was killed in cold blood, I was 5 and about to be killed after seeing my sister and parents die before me. When the bluet wheat through me mothers head I snapped and jumped on the man and killed him without a scratch. Then on I was a danger to be feared, you worse nightmare. Now I am a assassin and I and a hunter I am trained kill, toucher and capture. I work with my parter Lila and my real name well lets just say I tell no soul. I always will kill and I will always finish the job. So beware if I am sent to kill you don't try to run it will only be more painful.
