A classic wartime jidaigeki about the life of the famous samurai and first of the "Great Unifiers" of Japan, Oda Nobunaga, with Kataoka Chiezo and Shimura Takashi

Saburo is a high school student good in sports, but not very good with his studies. One day, Saburo travels back in time and arrives in the Sengoku period of 1549. There, Saburo meets Nobunaga Oda who looks and sounds just like Saburo. Nobunaga Oda is the son of a warlord and magistrate of the lower Owari Province. Nobunaga Oda though is physically weak and he asks Saburo to take his place. Then, Saburo as Nobunaga Oda attempts to unify the country of Japan.

The series is a historical drama aesthetically and boldly adapting the life of Oda Nobunaga in his teens up to his time as a warlord against his brother, Nobuyuki.

Japan is at war with itself. At Okehazama, Oda Nobunaga of Owari, rumored to be a fool, spectacularly defeated Imagawa Yoshimoto of Mikawa as he was leading a much larger host than Nobunaga's toward the capital city, Miyako. Nobunaga has decided to take Yoshimoto's place and lead his own forces to Miyako, so he is compelled to ally with the Azai clan in order to suppress Mino, a province lying between Owari and Miyako, by having his younger sister Oichi wed Nagamasa, the Azai clan's sucessor. However, Mino is also the birthplace of Nobunaga's wife, Kichou. Her former retainers and people are in Mino, and Kichou is vehemently opposed to the province's destruction, even if it is now in the hands of an enemy who overthrew her father, Saitou Dousan. But Nobunaga, who has embarked upon his path to conquest, holds to his course.

A story about a high school full of delinquents, and its elite class that has clones of famous warlords from Japan's Warring States period fighting it out.
