Description: Amaterasu, named after the Goddess of the Sun, is a Ninjutsu technique which uses the Mangekyo Form of the Sharingan Eye to create a powerful black Fire. This Jutsu is generated by the Mangekyo Sharingan. It has been said that anything within the Mangekyo's vision will burn to ash if consumed by the fire. The fire itself is said to burn for 7 days and 7 nights. Because of the amount of chakra needed to use the technique, it can only be used on a very limited basis daily. Though it is regarded as the strongest of Mangekyo's physical attacks, usage of the ability will degrade the eye further and lead the user to blindness.
Sasuke's excellent control of the black flames has even allowed him to use them to develop his own element, the Enton.
Users: Uchiha Itachi, Uchiha Sasuke.
