Saburou is sent back in time and meets Nobunaga Oda, who turns out to look just like him; brilliant but shy, Nobunaga asks Saburou to take his place.

Saburou earns a reputation in Owari for being a fool; Yoshimoto Imagawa's spy, Denjiro, attempts to infiltrate the Nobunaga family as a retainer.

Saburou meets Nobunaga's feared father-in-law, Dousan the Viper, leading to a surprising development.

Yoshimoto Imagawa's massive army of 40,000 attacks Oda's army of only 3,000; meanwhile, Denjiro tries to infiltrate the Oda family again, this time under the name Tokichiro.

Saburou forms an alliance with Motoyasu in an effort to take Kichou's homeland of Mino; meanwhile, Tokichiro remains diligent in his scheming to overturn the Oda family.

After his capture of Mino, Saburou has an unexpected encounter with a man who helps him and his men promote Yoshiaki Ashikaga.
