"Boss-Jounin" was not an offical title in any hidden village. The people who were referred to as such were often the head jounin of the village they represented, but were not the actual head of the village. While most villages referred to their head ninja as a "kage"of sorts, only the leaders of the five largest and most powerful villagers were actually recognized. To a certain extent the head shinobi of Sky, Shadow, and Marsh were recognized as "kage" as well- the Kamikage of Hidden Sky was recognized by Hidden Shadow, Hidden Leaf, and Hidden Mist; the Akumakage of Hidden Shadow was recognized by Hidden Sky, Hidden Cloud, and Hidden Sand; and the Yashakage of Hidden Marsh was recognized by Hidden Stone and Cloud. However, those that did not have a ninja recognized as a "kage" instead had a "shinobi-lord", often referred to as the "Jounin-Lord". These ninjas did the same duties and had the same resposibilities as the kage of one of the more major shinobi nations: assigning missions, planning battles, allocating funds for operations, and represented the village in international affairs. The "Boss-Jounin" was often the direct advisor of the village's leader, who also acted as the head shinobi's direct representative and messenger, being able to sign treaties and negotiate their details with just as much authority as their leader had if said leader was too indisposed be present himself or herself- something like a "vice-kage" or acting kage. Next to the leaders themselves, the Boss-Jounin was the most trusted ninja in the village.
