In February 1603, Ieyasu is granted the title of Shogun, and Yodo and Ono Harunaga (a retainer of the Toyotomi family) tighten their security. As Hidetada tells Gou of the marriage that is being arranged between Sen and Hideyori, she becomes upset. Hidetada however, convinces Gou that he regards the marriage as a pledge for peace. Gou accepts the marriage under the condition of letting her attend Sen's wedding ceremony. Even though being pregnant with Hidetada's fourth child, Gou accompanies Sen to the Osaka Castle where she reunites with Yodo and Hatsu.
