Jedi High Master (Earth-2356)

Jedi High Master was a Jedi who, rather than having all-around Jedi Master skills, only excelled in a specific area, much like warrant officers in military organizations. Notably, Anko Mitarashi and Ibiki Morino could completely understand the workings of the mind, making them experts in torture. They nevertheless possessed enough skill overall, as they were given the same opportunity as Jedi Masters in leading their own Padawan teams.
