Nobunaga as a shiba-inu is not a punchline that gets old. The show treats its premise with genuine fondness, letting the comedy breathe in small moments instead of beating you over the head with the joke. A Warring States legend reduced to a dog park standoff sounds disposable until you realize the show actually cares about these characters as small, stubborn versions of themselves. The jokes land quietest when they're just two ancient rivals being dogs in modern Japan, squabbling over territory and treats like the feudal ambition never left them.

Oda Nobunaga, the greatest warlord of the Warring States era, dies at Honnouji and wakes up in modern Japan as a Shiba Inu named Shinamon. He had once mused that his many sins would see him reborn as a dog, and Buddha apparently took him at his word. Now his warlord mind is stuck in the body of an adorable, instinct-driven house pet, and he swings between making the most of it and fuming at his new life. Other generals of the era, Takeda Shingen among them, have also come back as dogs, and their old rivalries pick up again at the dog park. The comedy comes from the gap between these fearsome figures of history and their new lives as pets, told in a light, slice-of-life style.
