You were his demon.
After death, you had been roaming earth as a demon, watching people and their daily life. Well, sort of. You had your eye on this one factory. The Rainbow Factory. You were quite fascinated, and loved to watch people die in the grinder. It was almost a daily occurrence. Unfortunately, you never knew that one person could see you. Walden. He was very curious with you. Especially your appearance. Red skin. Long, luscious deep red hair which fell to the floor. Tall, black horns with a beautiful demon-like tail. Then pure, black eyes with long lashes. It’s was indeed… beautiful.. Today was like no other, you were roaming around the factory like usual being nosy.. ((You could be walking around like usual, or flying, or watching a murder?))
