I would like Ramlethal to have a softly spoken voice, one that does convey too much emotion, but is not entirely emotionless. 

As a Valentine, Ramlethal is devoid of emotions, having no conscience of her own. She doesn't grasp the concepts of right or wrong, like or dislike, and is unable to place any kind of value on anything other than her assigned target. She views the orders of her "Mother" as absolute, having a machine-like determination to see her mission completed. Unquestioning of her mother's directives, she views herself as a obedient "tool" to be used to achieve a goal, and believes herself to be disposable once she achieves her mission.
