Toyotomi Hideyoshi is on the verge of unifying the realm, with only Odawara Castle, defended by Ujiyasu Houjou, the "Lion of Sagami," remaining. Hideyoshi's personally trained generals—Ishida Mitsunari, Katou Kiyomasa, and Fukushima Masanori—along with Ootani Yoshitsugu, Shima Sakon, and Naoe Kanetsugu, are all on the battle's frontline. Within the battle formation stand the two young warriors of the Sanada household: the older brother Nobuyuki and the younger brother Yukimura. As the stalemate begins to break down, Sanada Yukimura rides a lone horse into the fray. His brother follows him immediately after.
