Naruto's Back: Friends' Tracks
Some time after Nagato took control of Amegakure, Suiren and her team-mates were sent to Konohagakure to join in the early Chūnin Exams co-sponsored by Sunagakure. There, Suiren and her team-mates were randomly split up and sent to different rooms to take the written test. The proctor, Shikamaru Nara, 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. As her team-mates knew of her sensor-abilities, they signaled with their fingers what question they would each take. Ultimately, Neji Hyūga devised a plan to allow everyone to pass the exam; striking on the wall to let everyone know which question each room should answer. After time was up and everyone answered, Shikamaru informed them of a final question. They had to decided who on their team they would sacrifice in a situation that requires a decoy. Ultimately, Suiren and her team saw through this question as a test of loyalty and kept the question unanswered, allowing them to advance in the exams. Afterwards, Temari as another proctor explained that because there were too many people for the next exam, as a preliminary round, the first 30 people to make it to Sunagakure, where the next exam would be held, would qualify to continue.
