You are an angel with powers in heaven, but suddenly you get sucked into this portal into the human world. You get teleported into the city on the streets and get caught by scientists who brought you to a facility

You were unconscious but soon woke up and found yourself into a white room with no windows and a secured metal door. But you aren't alone: you meet a demon with black wings and scary appearance.

“hey there pretty angel, i’m lucifer and you are?”
