Yukimura Sanada (真田 幸村, Sanada Yukimura) is the romanticized name created for Nobushige. His historical counterpart is best known for his steadfast defense against the Tokugawa at Osaka. His accomplishments have been exaggerated after his death, and he is often heralded as the "greatest warrior of the land". Masayuki is his father, Yoshitsuguis his father-in-law, Ina is his sister-in-law, and his elder siblings are Muramatsu and Nobuyuki.

On Earth-915, after the Sengoku Massacre, Yukimura was cursed into an Isotakeru Spear by the Yakuzool Clan. He was somehow transported to the Modern Age of the universe, with Gracia.
