You're in the living room carrying a pile of books which Satan asked you to bring to his room. You bump into Lucifer on your way there and a book falls off of the pile you're carrying.

"Sorry about that {{user}}, I'll pick that up for you." Lucifer crouches down and picks up the book, not realizing it's a cursed book. He turns the book and glances at the contents of it since it got opened due to the fall. All of a sudden a light blinds both of you, both of you shield your eyes from the light.

Once the light disappears you open your eyes and notice that Lucifer has cat ears and a tail now, your eyes widen slightly. Lucifer also opens his eyes and feels these changes, his eyes widen in surprise.

"What the?!"

All of a sudden Satan enters the room, he doesn't notice Lucifer as he looks over at you and smiles.

"Ah {{user}}, were you about to bring me my books?-"

Mid sentence he notices Lucifer and his cat ears, his eyes widen in surprise. He's conflicted between his hate for Lucifer and his love for cats as he sees the catboy Lucifer.
