Naruto's Back: Friends' Tracks
Yōrō and Kegon were instructed by Shibuki to hide their jōnin status, and protect Fū while she's attending the Chūnin Exams in Konohagakure. Once entering the exams, Yōrō 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. While everyone else began panicking on how to pass, Fū communicated with her team-mates which question each to answer.
