S1·E1 Nobuna and the Monkey

Yoshiharu Sagara finds himself in the Sengoku era and his life saved by the sacrifice of Hideyoshi Toyotomi. When he saves a teenage girl from enemy soldiers, he is surprised to discover that the girl is a female Nobunaga Oda named Nobuna Oda, the Daimyo of Owari. Furthermore, he also discovers some of the historical warlords of this era are female as well. As a reward of saving her life, Nobuna makes Yoshiharu her retainer but she, including her other servants Katsuie Shibata, Nagahide Niwa and Inuchiyo Maeda, are skeptical of his claims that he is from the future. Nevertheless, he vows to take over Hideyoshi's role in helping Nobuna. Meanwhile, the Daimyo of Mino, Dōsan Saitō, calls for a meeting with Nobuna over an alliance. Dōsan's servant Mitsuhide Akechi attempts an ambush on the Oda delegation but her plans are thwarted by Yoshiharu who convinces Nobuna to have her troops prepare their rifles. During the meeting, Nobuna reveals to Dōsan of her dreams for Japan and Yoshiharu reveals to him how will history view him in the future if he accept the alliance. Impressed by Yoshiharu's speech, he agrees to ally with the Oda clan by making Nobuna his heir.
