Kirin

Kirin is an extremely powerful, one-shot lightning technique created by Sasuke Uchiha. The user draws lightning directly from thunder clouds to supplement the power of his or her strike and controls it with chakra. Due to the technique using natural lightning, which travels at 1/1000th of a second according to Zetsu, it is one of the most powerful lightning techniques. However, the preparation time required also decreases the technique's efficiency; if there are no active thunder clouds the user must create them by using Fire Release: Great Dragon Fire Technique or other such techniques to produce the necessary storm conditions. Doing this exhausted Sasuke's chakra supplies.

Once a lightning source has been acquired, shaping and guiding the lightning to the target requires very little chakra. In addition, usage seems to destroy the thunder clouds as the sky cleared up of clouds after use. As such, this technique can only be used once in a fight. However, the blast was strong enough to completely annihilate the Abandoned Uchiha Stronghold as well the mountain on which the stronghold was built, giving credibility to Sasuke's claim that the attack is unavoidable. Itachi withstood this technique by using Susanoo, though he admitted that were it not for his Susanoo, he would have been killed.

Influences
In Japanese mythology as following Qin Dynasty Chinese Mythology the Kirin is the highest ranked mythological animal below the Dragon and Phoenix, which are also in the names of techniques the Uchiha clan use.
