Yūra

was a jōnin-level shinobi from Sunagakure. He was also a sleeper agent of Sasori.

Background
As a Sunagakure ninja, he served as a trusted member of the Kazekage advisory council of Suna for four years. At some point in the past, he became a sleeper agent for Sasori, under the influence of his Memory-Concealing Manipulative Sand Technique.

Personality
Yūra was said to be an industrious and loyal person. From the little that was seen of him, this was true as he advocated new strategies and plans all geared towards improving the village. With regards to his loyalty, though two-sided, he was fiercely loyal to Sunagakure and after being awakened as a sleeper agent, showed great loyalty towards Sasori as well.

Appearance
Yūra was a tall man with black hair that hung over his right eye, a goatee and dark eyes. Usually he was seen wearing beige robe with black trousers and sandals. On missions, he wore a standard Suna shinobi attire, including a face-guard which covered his cheeks.

Abilities
As a jōnin and part of Sunagakure's council, Yūra was a very powerful shinobi. Sasori had chosen him to be a sleeper agent for good reason, which was certified when Yūra wiped out the entire force which was tasked with guarding Sunagakure's gate single-handedly, although there were many other jōnin and even Anbu present.

Kazekage Rescue Mission
Around the same time as Naruto Uzumaki's return to Konoha, Yūra and other members of Sunagakure's council were discussing intel gained from Jiraiya about the organisation known as Akatsuki, and he also had prepared a task force to be stationed around the borders of the village, to watch out for any members of Akatsuki. As he and Deidara approached the village, Sasori activated the technique to reawaken Yūra's memories of being an Akatsuki spy. After realising his true mission, Yūra killed the guards at the border, allowing Sasori and Deidara to enter the village to carry out their mission. Sometime later, Yūra was used by Pain as a sacrifice for the Shapeshifting Technique, becoming a replica of Itachi Uchiha and soon met combat with Chiyo and Team Kakashi. Ultimately, Yūra was defeated and killed by Naruto's Big Ball Rasengan. His corpse was later devoured by Zetsu.

Trivia

 * In the Disney XD English dub of the anime, his face upon death isn't shown.
