Kiba (swords)

is a set of twin swords of the Seven Swordsmen of the Mist. 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.

These weapons were first introduced in the anime, shown in the possession of Raiga Kurosuki, who uses them to instead channel his own respective Lightning Release techniques and to conduct natural lightning. The swords could also be connected at the hilts to form a larger double-bladed sword. 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 summoned by a revived Mangetsu Hōzuki with a scroll and then returned to a similarly resurrected Ameyuri Ringo, both of whom are previous wielders of the blades. Their abilities are fundamentally the same as they were in the anime, though it has yet to be seen if they can be connected or used to perform lightning based techniques.

Techniques used in the anime

 * Fangs of Lightning
 * Lightning Ball
 * Lightning Burial: Banquet of Lightning
 * Lightning Dragon Tornado
 * Lightning Strike Armour

Trivia

 * 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 Super Vibrating Lightning Release Sword. Raiga himself could use Lightning Release without the swords.
