Kiba (swords)

is one of the famous swords of the Seven Swordsmen of the Mist.

Appearance
It is a pair of swords, each with slim and straight double-edged blades. Both blades also have an upward-curved bladed prong near the tip of one side of the blade and another one near the base of the blade's other side. At their bases are smooth brown hilts with a round grey hilt.

Abilities
The swords have been imbued with lightning, granting enhanced cutting power in a manner similar to the high-frequency vibrations of lightning-based chakra flow. It is this capability that has resulted in these being claimed as the sharpest swords in existence. Even without lightning, they are very dangerous in battle, able to be used in combination with agile spinning movements, sweeping through the targets while the user also rotates. This, combined with the jagged nature of the blades allows for more damaging wounds inflicted.

In the anime, the user can transform and manipulate lightning freely, even perform their Lightning Release techniques without hand seals. They also boost the user's attack power to the highest limit, which allows them to perform high-level Lightning Release techniques with a minimal cost of chakra. These blades can channel the user's own respective lightning techniques or conduct natural lightning. As long as there is natural lighting to access, the user can battle continuously without tiring and launch lightning from the sky to strike anywhere within a large area. While meant to be used as a pair, the user can perform similarly with only a single blade. They can also be connected at the hilts to form a larger double-bladed sword. They can also be connected at the base of both hilts, increasing its versatility as a weapon. They are able to perform various powerful techniques, such as to manipulate the blades from a far, leaving their hands free while attacking the opponent at different directions simultaneously.

History
These weapons were first introduced in the anime, shown in the possession of Raiga Kurosuki. Ultimately, both were left behind at the bottom of a river in the Land of Rivers, after Raiga's death. Afterwards, in the manga, they were acquired by Kabuto Yakushi and given to the reincarnated previous generation Seven Swordsmen of the Mist, stored within a scroll along with four of the other acquired seven Mist swords. During the Fourth Shinobi World War, the reincarnated Mangetsu Hōzuki gives the Kiba to the reincarnated Ameyuri Ringo, who were both the previous true wielders of the Kiba.

In the anime, after being trapped in a bottomless marsh, Ameyuri gives the blades to Omoi as a thank-you gift from their exciting battle. At some point after the war, the blades were returned to Kirigakure and were stored into the vault along with the rest of Seven Ninja Swordsmen swords with the goal of training a new generation. A rebellious group proclaiming themselves the New Seven Ninja Swordsmen stole the seven blades to start a revolution against the modernisation and peaceful era of Kirigakure, determined to return to the days of the "Bloody Mist". Buntan Kurosuki took up Kiba like her father did previously.

Trivia

 * The Kiba are the first anime-only weapons to be adapted into the manga; later, their début wielder Raiga Kurosuki was also adapted into the manga. Also, during its original appearance in the anime with Raiga, the swords were depicted without tsuba. Its later depiction in the anime/consistent manga appearance with Ameyuri added tsuba to the swords' design.
 * While the nature of their abilities are fundamentally the same in their manga début, it has yet to be seen if they can be connected.
 * In the anime, although Omoi receives the swords from Ameyuri, he was never seen wielding or even carrying them afterwards.
 * Kiba's name and appearance is most likely based off of an old and rare style of Chinese sword of the same appearance and name.
