Echo Sharingan

The Echo Sharingan is the dojutsu belonging to the Uchiha and Uzumaki Clans. This eye is called Kami's eye with the ability to copy jutsus and kekkei Genkais. The first person to obtain these eyes was Mai Uchiha the sister of Madara Uchiha and Izuna Uchiha, but she lost her right eye to her brother.

After Mai "disappeared" the Echo Sharingan was long forgotten. Until a young boy going by the name Naruto Uzumaki-Uchiha unlocked the Echo Sharingan after being attacked by a mob.

Just like the regular sharingan the user must experience extreme emotional condition regarding someone precious to them or they must be in a life or death situation. Unlike the regular sharingan the user must have a pure heart and is deemed worthy by Kami herself.
