Tokubetsu Jōnin

are ninja who, rather than all-around Jonin training, have Jonin-level ability in a single area or skill, much like warrant officers of real-world militaries. They are elite specialists in their areas and are often assigned as subordinates to regular Jonin when their services are needed.

One example of a Tokubetsu Jonin would be Ibiki Morino. This character's unique ability to completely understand the workings of the human mind makes him a Jonin-level interrogation expert. Ebisu is another Tokubetsu Jonin that specializes as an elite teacher of young pre-Genin ninja. Other good examples include Tsume Inuzuka, Hayate Gekko, and Genma Shiranui.
