Hidetada Tokugawa succeeds his father as the second Tokugawa shogun, and within heightened anti-Tokugawa sentiments at Osaka, Nobuyuki Sanada heads to Osaka Castle in order to meet Hideyori Toyotomi. At the same time, Yukimura Sanada's life under even stricter supervision gets a jolt from an unexpected visitor.
I shall never forget the vow of 
righteousness I shared with you!
لن أنسى عهدَ الشرف الذي تقاسمتُه معك
Ich werde nie den Schwur der Rechtschaffenheit
vergessen, den ich mit Ihnen geteilt habe!
Je n’oublierai jamais le serment
Non dimenticherò mai il voto di rettitudine 
che ho suggellato con voi!
