Sajin (Genin)

is a shinobi from Sunagakure and a team-mate of Mujin and Mijin.

Personality

Sajin has long brown hair with two bangs falling out over his forehead protector, thus framing his face. He has an orange line running across the bridge of his nose. In terms of attire he wears a yellow scarf around his neck, a dark shirt with a grey triangular pattern and beige shorts. He also wears bandages around his lower-legs and arms, along with black fingerless-gloves.

Abilities
Sajin is capable of creating letters out of sand, which can be used to contact his allies.

Naruto's Back: Friends' Tracks
Shortly after Gaara was made the Fifth Kazekage, an early Chūnin Exams was decided to be hosted between Sunagakure and Konohagakure as a joined effort to promote Gaara's new status and help their allies in Konohagakure restore their reputation from the ruined previous exams. Sajin and his team-mates soon went to Konohagakure where the first exams would be held. Uniquely for the first exam, the written test was designed to separate each team by having their respective members take it in different rooms. As the proctor, Shikamaru Nara explained that the respective teams must score exactly 100 points to pass by having each member only answer one of three questions with different worth, the test-takers began to panic on how to go about this. Sajin however calmly performed his Sand Characters technique on the sand outside to tell his team-mates what question they should each take.
