Jinin Akebino (通�野餌人, Akebino Jinin) was one of the former members of the Seven Ninja Swordsmen of the Mist. He was evidently very skilled at utilising Kabutowari, a blunt sword that consists of a single sided axe and a hammer joined by a leather strap, which is said to be capable of breaking through any defence. This is achieved by first striking with the axe, before hammering it through the remainder of the obstruction with the hammer, resulting in the axe functioning much like a wedge. The 'swords' construction still allows the weapons to retain their individual capabilities and thanks to Jinin's expertise, both the axe and the hammer can be exploited to their fullest.

Meizu and his brother Gouzu formed the Demon Brothers. They were hired by Gato to kill the Bridge Builder, Tazuna, and therefor stoping the work on the bridge from the Land of Waves, making all of the Wave Country's citizens lose their hope. They both attacked Tazuna, who was guarded by Team 7. After a little quick battle, they were tied up to a tree and left there. The Demon brothers are a paragon of coordination attacking. Their large metal gauntlets house a retractable shuriken chain running between the two of them, which they can use to bind an enemy and then slice them to pieces. In the event that the shuriken chain is neutralized, they also have a release mechanism, to free them up for individual attacks. They use the sharp, poisoned claws on their gauntlets to shred their foes. As Kirigakure Chunin, they are renowned for their fighting resolve.
