Chidori is Kakashi's first original technique, though he now uses an S-ranked version known as the Lightning Blade. He created it around the time he was promoted to Jonin, and later taught it to Sasuke.

Description and Effect

This jutsu channels a large amount of lightning-chakra to the user's hand. The high concentration of electricity produces a sound reminiscent of many birds chirping, hence the name. Once the technique is completed, the user charges forward and thrusts the Chidori into the target. This produces heavy amounts of damage that is usually fatal to humans. This technique is classified as an assassination technique because of the speed at which it is performed, despite the loud noise it produces.
