I expecting to learn something about Nobunaga and shinobi. Instead, I found a show that followed a ridiculously OP "ninja" who tried to be cute. I decided to watch the 2nd season hoping they'd show the invasion of the Iga territory...
Regarding the story, art, sound, character, enjoyment, etc. I may have confused Nobunaga for being a ventriloquist. It was refreshing to see anyone who wasn't a samurai, but none really had any human-like depth to them. I've seen scripted NPCs more lively and animated. Don't think there was any real sound besides the voice acting and the OP. I think I most enjoyed seeing the overpowered ninja actually take some damage.
Overall, I'd say don't bother. You can get your does of cuteness watching something else, and can learn more about Sengoku era in the dozens of other stuff produced.
