Kiba (swords)

is one of the famous swords of the Seven Swordsmen of the Mist. 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 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 and manipulate 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 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. 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, either 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.
