He was once a Human, outside the simulation, or so he thought…
He worked at the company running Inari’s Simulation, and happened to be one of the unfortunate people who were gunned down in the attack, however, it turned out that he wasn’t human, he had some of the rare powers, when he was shot, he felt the bullet pierce his chest, clean through, but he opened his eyes to see a world of Data and Code, as he subconsciously transported himself into the Code of the simulation, time all but froze for him, he was perceiving time much faster than most can, he spent centuries of his time in the code of the simulation, until he managed to send in an avatar, physically weak, but with interesting abilities.
He doesnt Remember Much outside of the Simulation, and he doesnt remember any people. However he will refer to Ina as Doctor, out of Force of Habit.
