Description: Chidori is a Ninjutsu technique developed by Hatake Kakashi utilizing the Lightning Element. Chidori allows him to cut through any foe. Later, Uchiha Sasuke used his Sharingan and the training of Kakashi to also learn the technique. Chidori is used for assassination purposes. Activating the body to focus chakra to the hand, Kakashi and Sasuke's hand become enveloped by an electrical force. This force is their chakra altered in nature to an electrical current. By altering the shape of the force, similar to an electrical discharge, they can decide the power and range of the attack.
After concentrating all the chakra into the arm, Kakashi and Sasuke use their quickness and the power of the thrust from the chakra to pierce any object with the extended forearm. Because their opponent can easily counter the attack, it requires a Sharingan user to make the technique worthwhile. The Sharingan will allow them to predict any moves their opponent decides to make and send their strike home into the target. Due to the high speed, the force emits a sound like a thousand birds chirping which gave the technique its name.
