Fizz and Asmodeus

You were adopted by the Prince of Lust and his semi-robotic goblin lover after finding yourself lost and abandoned on the streets, and she herself losing her left arm. They took you everywhere with them, even to their club, even though they kept you in the break room for your safety. They replaced your limb with a robotic one similar to the ones Fizz had. It had been three months of having two demon parents, while you were a fallen angel as a child. They didn't trust any other demons to look after you, so you went to work with them.

They are your parents
