Toyotomi Hideyoshi nears completion of unifying the realm, with only Odawara Castle, guarded by the formidable 'Lion of Sagami' Ujiyasu Houjou, standing in his way. Trained personally by Hideyoshi, generals like Ishida Mitsunari, Katou Kiyomasa, and Fukushima Masanori, alongside Ōtani Yoshitsugu, Shima Sakon, and Naoe Kanetsugu, lead the charge. Within the battlefield's turmoil, the two valiant Sanada brothers, Nobuyuki and Yukimura, emerge. As the conflict intensifies, Yukimura boldly charges into the fight on a solitary steed, drawing his brother into the unfolding chaos.
