Isawa Ujina was the father of Isawa Tadaka, Isawa Tomo and Isawa Kaede. He became Master of Void the day after his daughter's birth. He held the position as long as he could, and finally resigned after the Scorpion Coup. He became the Nameless One in an effort to fight the poison that plagued him since he was attacked by the creature of the Shadows that took the place of his first wife, Doji Ninube.
