Jūbei Hyachi is the son of Ryo Hyachi and older brother of Tenkai Hyachi. When Jūbei's father died in an Order expedition, Jūbei became the new Vahashi, or Elemental Lord. As of Hyachi custom, the youngest child would have become the new Vahashi but since Tenkai was a hybrid, he was disowned. Jūbei has been in control of the elementalists, even through The Great God War.
