In Naruto's Footsteps: The Friends' Paths
Sen and her team partake in the joint Chūnin Exams co-sponsored by Konohagakure and Suna. For the first phase of the exams, Sen and her team-mates were split into different rooms, with her being placed in room two. After settling in, Shikamaru Nara, the first exam proctor, explained the goal of the written test on a monitor. Her team ultimately passed the first round since their combined score equalled 100 points as it was supposed to, and by leaving the bonus question unanswered. However, a preliminary round had to be held to lessen the many participants there were. The preliminary round involved a race to Suna where only the first 30 teams to arrive at the destination would qualify for the second phase.

Ultimately, her team were among the first 30 teams to make it. The next day, the second exam proctor, Temari, announced the start of the second round taken place within Demon Desert. During the second exam, Sen followed Shira's plan to help ensure all Suna-nin advanced to the next round. She began setting up her genjutsu all over the area to manipulate enemy ninja away from their allies. Eventually, they confronted Team Guy and sent them into the Sand Waterfall Pit. Afterwards, they went to meet with the other Suna-nin on how to handle the other enemy teams. The other Suna-nin however betrayed Sen's team, viewing them as weak and easy targets. As Sen was deprived of her fans and left open, her team was quickly saved by Team Guy, forcing the enemy Suna-nin to retreat. She asked how the Konoha-nin escaped the pit which Tenten simply stated she summoned a giant ladder. Questioning Team Shira's motives, Sen also reveals to Team Guy that Shira had only recently become a shinobi.

After Team Guy learns of the reason for the other Suna-nins betrayal, Lee angrily went after them to make them atone for their actions. After Lee's team-mates caught up with Lee and saved him from the other Suna-nin's group assault, her team arrived not long after, with Shira begging the Konoha-nin to leave them be, just as they were going to finish off the enemies. Shira insisted that their distaste of him is his own fault for the person he is right now, determined to be a man of recognition in the future. After Lee and his team agreed, Shira offered his scroll to one of the Suna-nin teams as they technically defeated his team earlier. As Shira's words finally reached the spiteful Suna-nin, they declined and instead gave Shira's team and Lee's team their own respective scrolls as they lost this battle. After the other Suna-nin left, Lee challenged Shira, to which he happily accepts. She watched their battle alongside the others until her team-mate loses. Shira reveals to everyone that he plans to join a special force on the northern outskirts to be with his sick parents after the Chūnin Exams ended. Sen teasingly asks Yome if she'll join Shira.

Later, as the exam was nearly over and her team had yet to find a matching set of scrolls, Sen's team decided to accept defeat and were glad to make it this far. They were then approached by Matsuri. Being a former student and fellow promoter of Gaara like Shira, she wished to battle him with no desire of obtaining their scroll. He gladly accepted and ultimately won the battle. Sen and her team then went to the main building to wait for the second exam's conclusion. Ultimately, the Chūnin Exams were ended early before starting the finals due to controversy happening in the second exam. Instead, it was decided by Gaara that a report on each participant would be sent to their respective village leader for them to decide if they would be promoted. Later, Shira, went through with his original plan and enlisted in the special force, where Sen said goodbye to Shira. As Yome also signed up, Sen gave more tease at Yome about her crush on Shira. After seeing her two team-mates leave, Sen hoped Shira and Yome are going to be all right.
