However they find themselves surrounded by the soldiers of Toyotomi Hideyoshi who seeks to unite Japan and help it grow into a strong country. Masamune, Shingen and Kenshin's forces manage to escape. Maeda Kanji who has been aware of Toyotomi's apperance arrived too late. Keiji then visits Maeda Toshiie and Matsu, aware of their alliance with Toyotomi Hideyoshi and asked why, which he replied that he agreed with Hideyoshi that the country is being weakened due to Oda Nobunaga's activities, but also agrees that he would be like him if he lost Matsu just as Hideyoshi's lost his beloved. Maeda also request Keiji to join them due to his history with Hideyoshi being his friend, but refuses and left. Souske reports to Shingen of Utsunomiya and Odawara have fallen by Toyotomi and placing his spies in their ranks and others and Mori's alliance with Toyotomi, having Shingen to have Sanada go to the west to Satsuma and protect Kyushu alonside forces there.

As Sanada's men set up camp, Sanada himself went to Azuchi Castle and entered, there he was shock to find Matsunaga Hisahide still alive but also encountered Oichi. Sanada then saw Hisahide holding a skull Oda used to drink sake from and plans to take it, but Sanada sees it as a mockery of the dead. Hisahide then tells Sanada that Date was defeated by Hideyoshi, which has shocked him but doesn't believe that he would be beaten and demands to return the skull. As he was about to take the skull from him Sanada is confronted by Kotaro Fuuma and both he and Hisahide disappeared, leaving behind explosives. Sanada survived the blast but was approached by Oichi and attacked him with her powers and was about to swallow him, however he manages to break free and starts to attack her, which freed her from a dark spirit in the form of Oda and surrounds them both. Date, who has survived and covered in bandages, awakes in an old house and was told by his men that he had lost but had protected him from Hideyoshi's next attack but didn't proceed. Date later thanked his men for their deed and admits he has underestimated him. Hideyoshi, who had recalled Date's men protecting their lord, remembered Keiji protecting him the same way. Keiji then recalled his fight with Toshiie and decide to go to Osaka to meet him. The next morning, Sanada wakes up to find Oichi unconscious and realise she was trying to stop Oda. Later he encountered remnants of Nobunaga's forces and are prepared to attack him, but are surrounded by Sanada's men led by Oyamada, forcing the remnants to not attack him but tells Sanada they will restore the Oda clan. As Sanada left with his forces, he looked back at Azuchi Castle, concerned about Oichi, and Oichi herself watch Azuchi Castle burning down. In Aki, Hanbei has completed the alliance with Motonari and are planning to launch an attack on Motochika.
