Jinin Akebino

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

Appearance
Jinin has a dark-coloured 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-coloured poncho cloth over a standard Swordsman attire, consisting of a sleeveless dark shirt and matching pants along with a waist-guard, 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 Hiding in Mist Technique.

Kenjutsu
He was evidently very skilled at utilising 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
Amidst the battle with the Third Division, the resurrected previous generation of the Seven Ninja Swordsmen of the Mist are summoned by Pakura and Gari, under Kabuto Yakushi's instruction, with the intention of overwhelming the opposition. Amongst their number is Jinin, who after being futilely bombarded by various techniques, retrieves Kabutowari from within a scroll in Mangetsu Hōzuki's possession. Entering the fray whilst concealed by a thick mist, Jinin begins a silent massacre, driving his axe into the adversaries' weapons, before hammering through their feeble defences. With Zabuza Momochi's defeat, the mist clears, exposing Jinin to the enemy. By the time Kakashi Hatake and Might Guy departed for Naruto Uzumaki's location the following day, Jinin had been sealed by the Third Division.

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.
