Shogun Masamori Hyuga was a member of the Hyuga Clan who staged a coup and deposed Emperor Takeshi Ofuchi of Yamato, becoming the de facto head of state in the process. He formed an alliance with Distreyd Thanadar XII during the Unification of Yamato, and their combined forces assaulted and conquered neighbouring kingdoms during the Yamatian Invasion. The Shogun fell ill during the Great War thanks to the sorcery of Distreyd XII who became the power behind the throne. It is assumed that Masamori died in the aftermath of the Cataclysm when Yamato fell to demons.
