If you want to defeat Nakama General Hanzo, just take the Fuma blue route and clear Mikatahara. Fuma's Honnoji route is also blue. Of course, if you want to play Nobunaga, you must first confirm that you have opened the Honnoji route with Aichi-chan. PS: If you want to hit Mikatahara on the Fuma blue route, after passing the Noh Island at the beginning, you must hit the Nakatomi River of Nagasou Gabe Motochika, otherwise you won’t be able to reach Mikatahara
