Lightning Release: Purple Electricity

Kakashi unleashes a stream of purple electricity from his hand to attack targets from a distance. This technique was powerful enough to summon rain clouds when shot into the sky. Kakashi was also able to creatively allow this technique to flow through liquid such as spilled alcohol.

Trivia

 * The term "shiden" is part of the idiom, which refers to a sword flash or a quick brandishing of a sword akin to lightning.
 * Kakashi creates this technique after he is no longer able to safely perform the Lightning Cutter from the loss of his Sharingan.
