Kagekenin is a smaller group than similar organizations, such as Akatsuki, being comprised of six members; one from each major nation. Its leader, Zoku, could be considered a seventh member. The group often works together, however, on rare occasions, Zoku will have them work individually. This also is a differentiation from Akatsuki, which operated in groups of two. The organization fully assembles to take on large missions or strikes as a unit.
