Nobuyuki Sanada

This character is Yukimura's older brother, whose actions during the Battle of Sekigahara created significant conflict with his brother. Despite this apparent betrayal, his true motivation was to ensure the survival and victory of the Sanada Clan, regardless of who ultimately became Shogun. He engaged in a notable fight with Yukimura at the Shogun Tournament, which was actually a means to impart a lesson. As they share the same age and appearance, there is speculation that they might be twins.
