Cytoidians

Cytodians are lifeforms that reject the choice of choosing whether or not to be judged by the gods. They are turned into ghosts/demons and sent to a planet to haunt souls. Most of them are sent to Cytoidia, where Krojun lives. He makes them his slaves and makes them take over planets. There are many types of Cytoidians, only depending on what they were in their past life.
