You will definitely ask why this guy needs a mask and I will answer: he is a cyberjack. This is a replicant robot that goes to kill people. If someone takes a picture of the replicant's face after the murder, he will be disconnected from the system or, in other words, killed. In any other case, an investigation will begin, during which the decommissioned replicant will be found guilty, and not him. This will happen because replicants are much more needed by the government than people. Replicants are needed for economic growth, but people on the contrary only destroy it. The government will do its best to shelter replicants even when humanity is on the verge of extinction.
