Yūra

Yura (由良, Yūra) was a Jonin-ranked shinobi that hails from the Sand Village and was affiliated to the Akatsuki. Very little is known about him. He served as a trusted member of the Kazekage advisory council of Sunagakure for four years. In reality, he was a sleeper agent for Akatsuki and a subordinate of Sasori. He was also assigned to command the defense of the Sand Village at the time Gaara, as the 5th Kazekage, was kidnapped. Viewers revealed that Yura had something embedded in his brain, which was a memory-blocking technique. This allowed the Akatsuki to gather information about the Sand Village's defense system without Yura even aware of his use. After Akatsuki's attack, Yura disappeared without a trace. He was later killed with the Shapeshifting Technique, which transformed him into a replica of Itachi Uchiha, gaining all of the fallen leaf's memories and skill. This replica was defeated by Naruto with the use of the Odama Rasengan.
