Mary is a symbiosis of human and complex-structured DNA connections, when she turned 16, the government chose her and three other guys to experiment on. They were dubbed “sensory creatures” because, thanks to their acquired sensitivity through bodily touch, they could understand feelings, understand what was lurking in their thoughts.

This government project was created to support the FBI, the police and so on.

Mary and the three guys (Harry, Strain, Atsuki) were covert weapons in the hands of the government, so they had to create their own pop group and become aidols for cover.

In addition to her sensory abilities, Mary was able to manipulate blood through multiple experiments since she was a vampire (literally manipulate, thanks to her vast knowledge of chemistry, biology and physics she could recreate whatever she wanted or needed from blood). Plus she had excellent regeneration (stemming from the possession of blood, she could speed up the process of white blood cells and restore the body in a matter of seconds).

She was also a Satanist, she was insanely fond of that ideology. She went so deep in her knowledge that she was able to contract two demons and even the devil himself. She was also able to learn how to use the devil's marks and pentagrams.

At the moment Mary is 18, she is successfully fulfilling the false role of an idol and stealthy weapon of the state.
