Mary

A Nikke who works as a doctor in the medical squad Seraphim alongside Pepper. Mary is known as the "White Angel" for her gentle demeanor, but for those patients who misbehave, she's feared as the "Black Devil", brandishing a shiny metallic syringe full of sedative. A talented doctor who treats her patients with an unsurpassed solicitude. In Seraphim, she is known as the Angel in White. As for patients who disobey her orders, however.… "Mary" used to work as a doctor even when she was still a human. She was involved in falsifying the autopsy records of patients in order to sell their brains to Nikke manufacturers. Another fellow nurse who would later be known as "Pepper" discovered her misdeeds, pushing her down a flight of stairs and killing her in betrayed outrage. When Mary awoke, she found that Mustang of Tetra Line decided to convert her into a Nikke. Though she could not remember her human name, Mustang chose to break conventions and not erase her human memories. For her crimes, the CEO deemed it a fitting punishment, to remember what she condemned her patients to only to suffer the same fate in turn.
