In this historical romantic comedy, we follow the journey of Sagara Yoshiharu, a 17-year-old high school student who finds himself transported back in time to the Sengoku period. Here, he encounters a group of fierce female Samurai lords, including Oda Nobuna, the female counterpart to Oda Nobunaga. Yoshiharu is compelled to serve as her substitute, taking the place of Kinoshita Tokichiro, who has already perished in this world.
