Kiba (swords)

is one the famous swords of the Seven Swordsmen of the Mist. It is a twin sword, each with a straight, double-edged blade of medium length. Their most noticeable trait is an upward-curved protrusion near the tip of one side of blade and another one near the base of the blade's other side.

They each have been imbued with lightning, displaying 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.

In the anime, they allow the user to transform lightning freely. 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 and to 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. They can also be connected at the hilts to form a larger double-bladed sword. They are able to perform various long-distance, powerful, and defensive techniques, both lightning-based or imbued with it. 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.

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. The swords are later adapted into the manga, where they are acquired by Kabuto Yakushi and given to the reincarnated Mangetsu Hōzuki, who stored them within a scroll an later returned them to a similarly reincarnated Ameyuri Ringo, both of whom are previous wielders of the blades. In the anime, after being trapped in a bottomless marsh, Ameyuri gives the blades to Omoi as a thank-you gift from their battle.

Trivia

 * The Kiba are the first anime weapons to be adapted into the manga.
 * It is unknown if the swords are imbued with lightning naturally, or if the users have to provide the chakra themselves, as Killer B did so with his Supervibrato Lightning Release Swords. Raiga and Ameyuri themselves could use Lightning Release without the swords.
 * 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, or used to perform lightning based techniques.
