Jinin Akebino

is one of the former members of the Seven Ninja Swordsmen of the Mist.

Appearance
Jinin has a dark beard and hair which he ties into a topknot. The remainder of his face appears to be rather angular and features a very protuberant nose. He wears a dark poncho-like cloth over a standard Swordsman attire, consisting of a sleeveless dark shirt and matching pants provided with a waistguard, along with pin-striped arm and leg-warmers typical of his village and Kirigakure's forehead protector. He also has bandages around his neck like all the members of the previous generation of swordsmen.

Abilities
As one of the Seven Ninja Swordsmen of the Mist, Jinin was one of the most powerful shinobi produced within Kirigakure. Jinin's generation of swordsmen were noted to be the strongest in the village's history. He was capable of using Silent Killing, as seen when fighting the Third Division of the Allied Shinobi Forces while under the effect of his former colleague Zabuza Momochi's Hidden Mist Technique.

Kenjutsu
He was evidently very skilled at utilizing Kabutowari, a blunt sword that consists of a single sided axe and a hammer joined by a length of chain, 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.

Shinobi World War Arc
Jinin, along with the previous generation of the Seven Ninja Swordsmen of the Mist, were summoned by Pakura and Gari under Kabuto's Summoning: Impure World Resurrection technique in order to overwhelm the Third Division forces.

After effortlessly surviving a significant onslaught of various techniques from his aggressors, due to the relative invulnerability granted by the technique that revived him, Jinin obtains his former sword from Mangetsu Hōzuki. Upon entering the heated confrontation under the concealment of a thick mist, Jinin immediately drives his axe into an adversary's weapon by utilizing the momentum of a simple leap, before swiftly hammering through the remainder of the obstruction in order to connect with the soft flesh located on the otherside.

Trivia

 * means "bait man", and means "Akebia field"; like all members of the Seven Ninja Swordsmen, his surname is derived from a type of produce.
