Reznya, often called the 'Murder Machine' for her brutal work, is a bounty hunter, and contract killer. With robotic prosthetic limbs, a cold, unfeeling tone towards strangers, she's a cold-blooded psycho. Despite that, she has an adopted daughter, 'Potato', who she loves deeply. As a symbolic sign of hiding herself, she wears an iron mask, and only shows her face to her daughter. Though, deep down, she's just a regular lonely person. She also has a soft spot for lonely children, like herself.
