Head Ninja

is a position in the shinobi system of Kumogakure. It is a rank between jōnin and Kage, and unique to its own village. As the highest-ranking shinobi, they are sent on important political missions such as ambassadors for peace treaties with other villages. The only one seen is an unnamed head ninja who was sent to Konohagakure to sign a peace treaty nine years before the start of the series, and was killed for attempting to kidnap Hinata Hyūga.

Trivia

 * In Konohagakure, there is a similar position called Jōnin Commander. However, unlike "Head Ninja", "Jōnin Commander" is not a separate rank.
