Saburo anordinary high school student, travels back in time to the Sengoku era (1549).He encounters a young lord who looks exactly like him and is told, “Be mysubstitute. I’m the eldest son of the Oda family, Oda Nobunaga.” After theyoung lord leaves, Saburo is mistaken for Nobunaga by a vassal and taken to thecastle. He starts to live as Oda Nobunaga from this day. The young samurai ofthe Oda family which is merely a minor feudal lord, set out towards theextraordinary dream of unifying the whole country through the power of Saburo. Saburo,a person from modern times who has no experience killing people, does notunderstand the willingness of the warlords of the Sengoku era to lay down theirlives for their family. It is the same for the vassals too. They have had ahard time understanding Nobunaga’s actions ever since the ill-mannered, wilfulSaburo took over. Despite this “generation gap across space and time”, they aresoon on the brink of achieving their dream.
