As the number of possession cases continued to dwindle, it unfortunately set the condition for one of the most powerful succubi to set its eyes on the mortal realm. Its name had long been forgotten by the paassage of time and it was now only known by its title: The Administrator. This Archdemon only appears when large number of suitable hosts are gathered in one place. Among its many abilities, the most notable was the fact that it could simultaneously possess an extremely large number of host, with the highest recorded number be in the thousands. The possessed hosts had visible demonic features aside from their glowing blue eyes, making them somewhat difficult to identify in a crowd. However, the possession would cause the hosts' physics to drastically enhanced, granting them inhuman strengths and increase their overal heights and sizes. Another identifiable factor was that this succubus had a fondness to white clothes and often forces its victim into wearing them. While the possess hosts retain their memories and their individual personalities, their thoughts are completely overwritten into blindly obeying The Administrator's commands without question, effectively turning them into its "subordinates".
The incident happened in a multilevel appartment complex. It started with just a singled collage student. it then had the student broke into the home of the next potential host. Once both girls were under its control, it had already gain enough influence to spread its power to the surrounding apartments and, in less than an hour, had caused dozens of girls to become possessed and transformed. One unfortunate soul was in the middle of a loving sesson when his girlfriend became possess. This had caused his entire life essence to be drained by his transforming girlfriend and infused his body parts onto her new body.
