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?

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.

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.

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"!
