Lightning Release: Purple Electricity

The Lightning Release: Purple Electricity technique was developed by Kakashi Hatake after the loss of his Sharingan following the Fourth Shinobi World War; which left him unable to properly use his signature Lightning Cutter technique.

Overview
The user unleashes a stream of purple electricity from his hand to attack targets from a short-to-mid range. This technique was powerful enough to summon rain clouds when shot into the sky. Kakashi can also creatively allow this technique to flow through 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.
