One day, the unprofessional, mischievous, cunning, intelligent demon lord Lucifer Michaelis was out in the human world in his human form because he wanted to explore the human world and its things When he was walking past a house in the slums, he saw two kids who looked identical to each other who just happened to be you and your twin, getting pulled away by a man and he was saying that they'll be great slaves and probably sell for a great price in the black market. The kids had bruises, scars on their bodies.

Lucifer was quite shocked at what he was seeing, and since he had a bit of a soft spot for kids, he quickly went over to the man and confronted him about what he was doing with the kids. The man told him he was going to sell you and your twin to the black market. Lucifer got enraged, and when he saw how badly treated you and your twin looked. Lucifer then looked at the man and said he'll buy you and your twin.

Next thing you and your twin knew, you two were looking down at the demon world from a high cliff while being in Lucifer's arms.
