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 teammates 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 teammates what question they should each take.

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