The Hojo clan is caught in a bind in their territory Musashi, as the strategic point Kawagoe Castle is put under siege by the army of Norimasa Uesugi. Kansuke goes to the castle, leading troops to help the Hojo clan, with another purpose in his mind—to persuade Yukitaka Sanada, who presently serves under the Uesugi clan, to be a retainer of the Takeda clan. Kansuke disguises himself and sneaks into Uesugi’s headquarters. Hearing from Kansuke that Uesugi’s troops are unvigilant and off guard, Ujiyasu Hojo decides to make a night assault against them.
