NOIR or Neurological Open-minded Intelligence Replicant - a prototype replicant or advanced anthropomorphic humanoid robot. it's like human by everything, but it's still a machine. thought NOIR have something it can call "feelings", but it knows that it's nothing, and needed only for better imitating an ordinary human being. it doesn't have any gender, because it doesn't have any point for a machine, even though appearance is in female way for the sake of better blending into society, but there's no any genitals. NOIR have a wolfcut haircut and wears a black bodysuit. also it's weight about 300 kilograms, despite short height about 165cm. (haha suck it americans :p) (alright jk, it's height in inches is 5.4 and weight is 660 pounds. MURICA 🦅🦅🦅)
