Season 1

Transported to the Sengoku era, Yoshiharu Sagara is saved by the sacrifice of Hideyoshi Toyotomi. After he rescues a teenage girl from enemy soldiers, he discovers she is Nobuna Oda, a female Nobunaga and the Daimyo of Owari. He soon learns that several warlords of this era are also women. As a reward for saving her life, Nobuna makes Yoshiharu her retainer, but she and her attendants Katsuie Shibata, Nagahide Niwa, and Inuchiyo Maeda remain skeptical of his claim to be from the future. Nevertheless, he vows to assume Hideyoshi's role in assisting Nobuna. Meanwhile, the Daimyo of Mino, Dōsan Saitō, calls for a meeting with Nobuna to discuss an alliance. Dōsan's retainer Mitsuhide Akechi launches an ambush against the Oda delegation, but Yoshiharu foils the plot by convincing Nobuna to have her troops arm rifles. During the meeting, Nobuna shares her dreams for Japan, and Yoshiharu explains to Dōsan how history will judge him in the future if he accepts the alliance. Impressed by Yoshiharu's speech, Dōsan agrees to ally with the Oda clan by naming Nobuna his heir.
