Daisuke Hyuga was the great grandfather of Shogun Masamori Hyuga and a member of the Hyuga Clan. He was last seen 20 years prior to the Yamatian Invasion. According to a Yamatian legend he had lost his wife Matami Hyuga during a brutal raider attack on his palace. In his desperation he sold his soul to the demon Yurius in exchange for bringing his beloved wife back to life. Yurius answered the call, and the palace was covered in darkness. Neither Daisuke, Matami nor any of the servants were ever seen again.
