Toranaga

Toranaga mentions to Yabushige that since he can't send his army to Osaka without the possibility of being killed, he made arrangements for Mariko that would be done in such a way that she would be eventually be killed while in Ishido's custody. Even due to his insistence that she's not "his prisoner", her death would stage the end of the Council of Regents from backing Ishido. Even Lady Ochiba pledged to make sure the Heir's army wouldn't come out to support Ishido as well.
