Though he is over 6000 years old, Jedah is the youngest out of the three High Nobles of Makai.
Jedah was always distressed about the future of Makai (Japanese for "demon world"). He believed that if Makai was left under Belial's rule, the master of the Aensland family and the true ruler of Makai, then it would grow old and begin to decay. Belial would most likely say that such is destiny and life. Jedah considered Belial to be an abomination, and actively sought out the opportunity to kill him, waiting for the right time to strike.
After the death of Garunan, the master of the Bosital family and the oldest of the three high nobles, Jedah had a young confidant named Ozomu. Simply put, he was a gourmet. The reason he came under Jedah was to be able to eat delicious souls. As a noble, his skills were second class, but his ability to deceive others were first class. He was a genius in using others. He advised Jedah about using the gate of Makai. Jedah, being confident in his ability to absorb souls, agreed to this. He ordered Ozomu to break a part of the seal to open the gate more.
