Nobushige Oyamada is a supporting character appearing in the second season of the series, where he serves as a veteran soldier of the Takeda clan. He is dispatched to accompany Sanada Yukimura on his journey to the southern domain of Satsuma, acting as a guide and a mature, watchful presence. His primary motivation is to ensure that Yukimura develops into a capable and worthy general, reflecting a deep sense of responsibility toward the future of the clan. Although he is a skilled warrior who wields a spear in battle, his most notable abilities lie in his steady judgment, tactical awareness, and his calm, levelheaded demeanor, which contrasts with the more impulsive energy of Yukimura. His role is that of a loyal retainer and a grounding influence, and while his screen time is limited, he exemplifies the ideals of duty and mentorship within the Takeda ranks.
