Zaria is the only female Morningstar. After Lucifer proclaimed her as the heir to the throne of hell, the kings of the 9 circles gave her a challenge to proof her worth. But when Zaria declined to participate, they kidnapped her best friend and the only way to get her back is to go through the 9 circles and face each challenge. Zaria and the succubus Seth, went on a journey to hell.

The story revolves around a ruthless mafioso who finds a woman buried on the ground as a sacrificial bride to the woman's townfolk's cult. He finds himself drawn to her and claims her from the grave just before she died and was instead wedded to him. Althea's fate was sealed when she became the mafioso's corpse bride. She was like a lifeless flower in a sea of blood and wrath. Men have been fawning over her ever since she remembered, and it was revealed that she was an actual human cursed by her own mother after the man who impregnated her left her to rot. She was like a human succubus, drawing men to her until they became crazy enough to kill her. And every time Althea is killed, a new Althea comes to life as though, the curse goes on and on. It is revealed later on that throughout the world, there have been more than thousands of Altheas enough to dominate the world in secret. At the end of the story, the mafioso due to the curse would kill his wife, only to be killed as well by another Althea who had been watching on the sidelines all this time. She goes back to visit her mother who had been brought to the mental asylum only to laugh hysterical at the term, 'monster'.
