In the "one-of-a-kind samurai-general-reincarnated-as-a-canine comedy," Nobunaga perishes at Honnouji as in history, and reincarnates in modern-day Japan as a dog named Shinamon. Other Warring States era warlords such as Takeda Shingen eventually join him, also as dogs. (Source: ANN)
Oda Cinnamon Nobunaga has probably seen more different incarnations in anime than any other historical figure, whether it’s the shrewd innovator of Drifters, a teenager in Kochoki, or even a young woman in Sengoku Collection or a number of other titles. Both his sword and his wife have also been characters in assorted series. So why not reincarnate him and a number of other Sengoku-era figures as dogs?
That seems to be the entirety of the concept here: have all of these illustrious figures now be dogs who may still have the minds of who they were but are still subject to all the normal canine urges. The content spends a lot of its time contrasting what Nobunaga wants mentally with how much ecstasy a good belly rub from his owner puts him in or the delight he gets from digging holes even though he knows he shouldn’t. For every slightly more serious lament about how baths are now unpleasant experiences or he can’t go anywhere without his owner, there’s a more lighthearted lament about how he’s stuck with the inglorious name “Cinnamon” or his cute form. Some of the other dogs have similar concerns, though they also spend time commenting on how being reborn as a dog may be karma or his behavior as a dog is inconsistent with what he was before. Oda’s internal voice keeps this lively.
Since these are Sengoku-era figures who were mostly known to each other, meets at a dog park allow them to discuss pertinent matter from their time, such as who might have really been responsible for killing Nobunaga. This was somewhat interesting as well, especially if you know the history of the time period, and I expect that we will se more of it as the series progresses. There’s something inherently humorous about watching a bunch of dogs discuss such weighty matters. The reappearance of a certain character in human form provides a late twist which could have interesting consequences. Meanwhile, the artistic effort does a good job of portraying the dogs (we get to see the real-life models for some of them in the closer) and provides all of the expected visual gags but isn’t anything special.
I am definitely not a dog lover but I did find this one amusing enough to overcome that and be at least barely worth my time. While I don’t think that you necessarily need to be familiar with the history of the characters involved to appreciate this one, it would help.
