Nobunaga no Shinobi tells about the exploits of a shinobi called Chidori who works for Oda Nobunaga, a prominent (or rather, the most popular) warlord in Sengoku era (16th century). Basically it revolves around the things Chidori do as summoned by her lord. The episodes are short yet sweet. Characters are in chibi style and as such, it is comedic in nature and viewers should not expect serious historical accuracy in the series. However, those who appreciate Sengoku era history will probably enjoy this series better because they are familiar with the names and the character traits. The humor is lighthearted and it's rather manzai styled inmy opinion, which I enjoy very much. The plot moves fast due to the length, but it doesn't deter the comprehension of the story at all and there is no time to get bored.

Overall I give it a solid 9. Definitely recommended for casual anime watching to relax.

P.S.: I absolutely love the opening song!
