The Ambition of Oda Nobuna - S01

High school student Yoshiharu Sagara wakes up to find himself in the middle of a raging Sengoku period battle. He is saved by the legendary Hideyoshi Toyotomi, but at the cost of the hero's life. With his dying breath, the warrior begs Yoshiharu to become a feudal lord in his place. Now that the course of history has been changed, Yoshiharu vows to keep the timeline from diverging any further. Yet after rescuing Nobuna Oda, whom he discovers is actually the fabled Nobunaga Oda's female counterpart, Yoshiharu realizes he has been transported to an alternate reality where most of Japan's historical warlords are now cute girls. To set things right and find a way back home, Yoshiharu agrees to become one of Nobuna's retainers and help her in a conquest of Japan. As Nobuna begins her campaign, Yoshiharu discovers that the history he learned from playing the video game "Nobunaga's Ambition" lets him predict future events and turn the tide of war. Using this invaluable gift to aid the Oda clan's beautiful generals, Yoshiharu hopes to help his new lord fulfill her dream and win the hearts of women everywhere.
