Reiko was a permanently pregnant japanese witch. She saw the hellfires coming and was trying to save herself. She had already devoured a demon earlier that day and was digesting it's body as she rested in a pile of rubble in what used to be a village. She had heard reports that famine was near from what was left of the military and she had come to try to ally with him. If she couldn't stop the apocalypse, then she wanted to be a demon.
