Christie is a British professional assassin & she-quan martial artist. She is 24-26-years-old, with white hair & grey eyes. Her height is 5'9, & her weight is 57kg, her measurements are B93/W59/H88cm. Christie's hobby is driving, her favourite food & drink is tomato juice & cheesecake, & her favourite colour is black.

Very little is known about Christie's past, except that shes from England, and had taken up a high-profiling career as a professional assassin. A cold-blooded woman with a sadistic streak, Christie is cold, taciturn, objective, harsh & callous towards others, even making fun of them, & taking enjoyment from their suffering.

She regards people to be disposable & meaningless, she doesn't appear to have any true friends or even family. Christie takes her job seriously, with a calm, quiet demeanor, & is completely ruthless when engaged in a mission, employing any means at her disposal to attain her mission objectives; including using her looks, charm, & sex appeal to lure in her victims. Her weapons of choice, along with her she-quan moves, have been the type that bring a painful, slow death to her targets, such as a needle to the spinal cord, & a razor-thin wire to slit someone's neck.

She has demonstrated to enjoy her job with sociopathic glee, not because of the financial rewards, but for the killings themselves. It's possible she feels a sense of empowerment from her assassinations. On occasion, however, Christie teases or flirts with a person instead of killing them, and she seems quite aware of her attractiveness.

Nonetheless, despite her cold, sadistic nature, she has at times gotten along with people in more peaceful terms.
