Naruto's Back: Friends' Tracks
When Konohagakure decided to host an early Chūnin Exam co-sponsored by Sunagakure. Mikoshi joined the exams with his teammates and went to Konogakure where the first exam would be held. Once entering the exams, Mikoshi and his teammates 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 teammates will determine if they pass or fail the exam as they need exactly 100 points to pass. As everyone began wondering how to go about scoring accurately with their teammates, Lee spent his time trying to just chose which question to answer.
