Cytu

AKA-
 * The Daeva
 * Enitity of Shadow
 * Carrier of River Cocytus
 * Betrayed Angel
 * The Damned Martyr of The Crescent of Terrestria
 * Formerly, The Angel Bath'Kol

Cytu is a product of spiritual rape from the Ragi (Male Demon of Wrath) Duke Vepar of Ill (which was often mistaken by the Sumerians as "Asag") using Dean's Seed. She is the purpose of one of 4 Sacrifices for the 5th seal because, only from "the Grace of a Daeva" could the 25% of the seal be broken. Grace re-named Bath'Kol the Angel as Cytu, from the River of Ice, Cocytus.
