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 choice test, Shikamaru revealed a bonus question, asking to which team-mate you would leave to be a decoy. 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 a 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 was the first to move out. Arriving at the checkpoint, he and Kegon locked Fū in a room to keep her from doing something troublesome, though she managed to escape anyways. After finding Fū, who took a giant scorpion down saving Team Asuma, Kegon and Yōrō took her back with them. The next day, Temari — the second proctor, announced the start of the second round that would be held within the Demon Desert.
