Purified Souls

Estelle Lumia is the heir to her father's store of books. She inherits the book store after both her parents die from a unknown shadow filled with pure evil & hatred. Estelle spends her days going from organizing books, to purifying various residences with the knowledge her parents taught her. Occasionally, we see the weird customers she helped every once in a while. She also starts living with a very unique girl, not human at all?
