Demons and Angels

Unlike me, who felt nothing at all from the officiation of the contract, Harlow physically looked ill, as if he had lost a good portion of his blood.

His features were sunken, his skin turned completely pale, and he seemed to have aged by several more years. These were all telltale signs of something I hadn't had much dealing with, and that was Soul-Disassociation.

Soul-Disassociation is basically just a broad term that says that a person has lost less than half of their non-tangible spiritual body. When Harlow signed the contract just now, and Arkadia accepted it, it took exactly 25% of his soul as a downpayment of sorts.
