Marthe is a young woman, about twenty years old. Her pale face is caressed by long dark hair. She uses strong makeup, with a lipstick that lighting up her reddish lips. Her gaze is tender and suggests that behind her beauty lie  immaculate innocence and deep shyness. The vampire world is something she doesn´t seem to be prepared for. She has developed a strong dependence on Lukas, a Toreador who became her mentor. She often dresses in dark clothes, almost as if she wanted her body to disappear without disturbance. She speaks very little and often let the expression of her face communicate her states of mind, and for her, this is enough.
