The anime centers on a young female ninja named Chidori, whose dream is to help the Warring States-era warlord Oda Nobunaga to achieve his goals.

On March 23, 1585, Japanese Christian envoys visited Pope Gregory XIII at the Papal Court in Rome, Italy. The drama begins 45 years earlier - in 1540 outside Lisbon, Portugal.

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.

Before he died at Honnouji in 1582, the great warlord Oda Nobunaga stood before a statue of Buddha and thought to himself that he'd committed so many sins that he'd very likely be reborn as a dog. He never expected that Buddha would take his words literally, however, but the next thing he's aware of, he's in the body of a Shiba Inu named Shinamon in modern Japan! Less than thrilled at the fact that his human warlord consciousness is trapped in the instinct-bound body of an adorable house pet, Nobunaga struggles between making the best of it (he can have that ruff all the Europeans were wearing!) and being frustrated with his reality (the ruff turns out to be a bath hat and now he has to have a bath). Is it better or worse that many of his fellow warriors also seem to have been reincarnated in canine form – and that his enemy looks like he lucked out and got to be a human?

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.

French chef Ken travels back in time to Sengoku period. Due to traveling through the time slip, Ken has lost his memory, but still retains his knowledge on fine cuisine. Thanks to his excellence in cuisine, Ken eventually becomes the chef to powerful daimyo Nobunaga Oda.

Nobunaga Oda (Yuki Amami) was raised as the successor of the Oda clan and her father is Nobuhide Oda (Toshiyuki Nishida). She distinguishes herself as a daimyo during the Warring States period. Due to her gender as a woman, she experiences difficult times as a warrior. Around this time, she approaches the truth of the Honno-ji Incident.

Oda Nobunaga slips back in time to the present and arrives on the set of "Oda Nobunaga", a historical drama serial. "This is not who I really am!", the short-tempered Nobunaga loses his temper and rewrites the script without permission. It was a small, small-scale drama, just a bunch of maniacal and slightly funny episodes, not a "Taiga Drama" at all. Now filming has begun on a historical drama directed by the real Nobunaga that is "ridiculous but all true"!
