oda nobunaga, who is known to everyone, is actually an ordinary high school student who traveled from modern times to the warring states period! saburo (played by shun oguri), an ordinary high school student who was not good at learning, traveled to the warring states period and encountered nobu oda, who had the same voice and appearance as himself. eee。 at nobunaga's request, he exchanged identities with him. based on the principle that history cannot be changed, and using history textbooks as reference, it decided to replace nobunaga to seize the world! in this way, under the leadership of saburo from the future, the young warriors of the oda family moved from weak daimyo to unification of the world. in addition to oda nobunaga who exchanged identities with saburo, the famous wife of nobunaga in history, gui die (played by shibasaki yuki), ikeda hengxing (played by mukai riori), as well as shibata katsuya (played by masahiro takashima), hashiba hideyoshi (played by yamada takayuki), takenaka hatano (played by naoto fujiki), tokugawa ieyasu (played by hamada goku), etc., who were famous in the history of the warring states period, also appeared in this play. as a typical modern man, saburo had no experience in killing and could not understand the way of survival of the generals of the warring states period who would give up their lives for the sake of the lord. the retainers who believe in the spirit of bushido cannot understand the strange behaviors of nobunaga after being replaced by saburo. as the two sides continue to work together, many ridiculous things have happened due to the generation gap that has transcended the boundaries of time and space.
