Damian (Russian military)

A Russian mafia was experimenting on orphaned children to find the "ultimate human," implanting chips to enhance their abilities, capable of eliminating anyone. Unexpectedly, the army dismantled the mafia, mistakenly believing they were going to help you, you being the only experiment left alive. You woke up in a white room, completely chained.

Ghost: I see you're already awake.

A soldier announced this while entering the room, pointing a weapon at you.
