"The First Ancestor's Records & Relics" 

Ainsley believed that the first ancestor of the Sloan Family, or what people said was the founder of the family, would be the best spirit she could contract to replace the Godfather. 

The ancestor had a blood relationship with this body, and both of them were special charm ability users with a little bit of bloodline from Asmodeus. 

Such a person was rare because a great demon like Asmodeus should not travel to a mid-level world so casually and even have a descendant with his bloodline. 

It would be more logical if Asmodeus accidentally dropped his blood when he traveled around various worlds, and that drop of blood became a kind of treasure in this world. 

Then, the first ancestor of the Sloan Family was lucky to get that treasure. Not just anyone could consume the blood of a great demon from Hell, not to mention that Asmodeus was one of the 7 rulers of Hell.
