Nobunaga no Shinobi (信長の忍び) is a Japanese four-panel manga series by Naoki Shigeno, serialized in Hakusensha’s seinen manga magazine Young Animal since 2008. An anime television series adaptation by TMS Entertainment began airing in October 2016 and is being simulcast by Crunchyroll under the title Ninja Girl & Samurai Master.
Rescued from nearly drowning in a river, a young Chidori yearns to pay back her savior’s kindness. Though her cute and innocent appearance might not show it, she is actually a highly skilled ninja, so years later, Chidori and her friend Sukezou come to serve under the man who saved her—the ambitious warlord, Nobunaga Oda. As Nobunaga fights off invading forces and sets his sights upon neighboring lands, Chidori is assigned vital tasks to assure victory, such as gathering information or assassinating key figures. Between taking on these important missions and dealing with the colorful cast of Nobunaga’s family and servants, the young ninja is always ready to do her best to lead her master toward greatness.
