Summary: The Spirit King is known to a few lucky shinigami. Even little is known about what he does. Except that the Oken, The King’s Key, is the only way to him. What no one knows , is that the Oken serves another purpose. When the Oken was first created he took the four main portions of the keys power, life/light , death/darkness, order, and chaos, and chose four humans to contain each component. The power is passed when the old carrier passes it on to a trusted family member, this was at least 10,000 years ago,. In those past 3,000 years a new group have been trying to hunt down those carriers. It is now the year 20XX and a several new carriers have been chosen, but they too ,whether they know it or not, are being hunted. Rex Micheals has just moved to Karakura, Japan from the United States with his dad. He not only has to worry about learning a new language, and (not) getting into fights, not to mention these sudden disappearances, but also these creatures that only a few can see. Rex, along with the help of his tutor and best friend, Ryohei, a shinigami that has been ordered to watch him, Karmah, Mordred , a fullbringer that occasionally argues with Rex, and two other friends Sachi ,and Daisuke, try to find out who or what is causing these strange incidents, and put an end to them.
