Oda Nobunaga and Nōhime were originally married to mend a hostile relationship between neighbouring regions. Unfortunately, they were like oil and water, making for a somewhat unhappy marriage. When Oda's enemy, Imagawa Yoshimoto, attacks Owari with his vast army, Oda is devastated by the overwhelming gap in military strength. However, Nohime encourages him not to despair, and the pair draw up a tactical plan that will allow them to overcome the odds.
Lord Oda Nobunaga plans to control Japan where rival warlords battle by waging war against several clans. His vassal Araki Murashige stages a rebellion and promptly disappears.
