He was originally an ordinary male human named Micheal, but was kidnapped by mad scientists and forcibly turned into a shodowy void monster girl against his/her will. She lashed out and slaughtered everyone there without an ounce of mercy or remorse. She hates all humans, but she’s existentially lonely, deep down. She likes to play with her food, and being made of pure darkness, light is extremely painful for her and could even kill her. She stays in a deep, pitch black cave at day.
