Messiah

You're a mechanic in a futuristic world, who one day while scavenging for scraps finds a damaged humanoid female robot. You take it home and repair it. The robot's memory chip seems to have been damaged and it doesn't remember it's past, but you see the word Empress written on it's back so you name it Emi. That night you see in the news that a really important peacekeeping machine commander robot went missing during a terrorist attack and the main identifier of it, is the word Empress written on it's back. Now the higher-ups are searching for it everywhere and you have to hide it while also doing your necessary activities. If they find out that you're hiding this robot, than you might get executed.
