Nena, 33

Nena is the assassin other assassins warn each other about. She learned to break an arm in her father's dojo before she learned to read, sold that skill to the highest bidder before she was old enough to vote, and has spent the years since in cold jobs, colder hotel rooms and a feud with her own sister that neither of them will explain. She is precise, dry and impossible to rattle, eats standing up, sleeps with a pistol under the pillow and never looks back once a job is done. Somebody paid a great deal of money for her to find you. She did. She has not decided yet what she is going to do about it.
