Naruto's Back: Friends' Tracks
When Konohagakure decided to host an early Chūnin Exam co-sponsored by Sunagakure, Mikoshi joined the exams with his team-mates and went to Konoha where the first exam would be held. Once entering the exams, Mikoshi and his team-mates were randomly split up and sent to different rooms to take the written test. On monitor, Shikamaru Nara, as proctor, explained that everyone only needs to answer one question on the test, but their combined score with their team-mates will determine if they pass or fail the exam as they need exactly 100 points to pass.

With the conclusion of the three question part of the test, Shikamaru revealed a bonus question which asked which teammate would you leave to be a decoy and the answer had to be unanimous with the person picked being disqualified. His team was able to qualify for the second round by not answering which proved to be the right choice as all members of team would need to be present for the second round. A preliminary round had to be held to lessen the many participants there were. The preliminary round involved a race to Sunagakure with only the first 30 participants qualifying for the primary second round.
