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.

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, and with that his team were the first move out.
