Sen

is a kunoichi of Sunagakure and a team-mate of Shira and Yome.

Background
While still in the academy, Sen and Yome watched from afar as Shira was mocked and ridiculed by their peers. Despite being banned from joining the academy because of his lack in ninjutsu and genjutsu, Shira continued to train himself in taijutsu. Sen and Yome ultimately came to admire the young man and were happy for him when Gaara, the new Fifth Kazekage, revoked the rules to allow Shira to attend the academy.

Personality
From all indications, Sen is a very collected individual who cares about her team-mates.

Appearance
Sen has brown eyes with black pupils and sandy brown hair tied in a ponytail with two strands of hair positioned on each side of her face and two braided strands. Like most shinobi, she wears her forehead protector across her head. She wears a mesh armour body suit under a red tube dress with a blue purple belt, fingerless gloves, and black shinobi sandals. She also carries two small white fans with fur.

Abilities
Sen is an adept genjutsu user, able to trap her enemies, like Team Guy, multiple times without them even notice. One of her techniques uses the pollen of a cactus to trap multiple foes at a time, forcing them to cross the same spot several times in their mind. Since Sen prepared this trap ahead, it stands to reason that she's also very intelligent.

While Sen is noted to be highly skilled in using her fan during close combat to fight or block her opponent's attacks, her skills are noticeably weaker unarmed. She also uses them in conjunction with her genjutsu.

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, Sen's team confronted Team Guy and sent them into the Sand Waterfall Pit. Afterwards, Sen's team 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.

Recognizing Shira's greater struggles than his own, Lee angrily went after the other Suna-nin to make them atone. Sen's team and Neji's soon caught up with the overzealous Lee and saved from the Suna-nin's group assault. Despite leaving them prime for defeat, Shira begged the Konoha-nin to leave them be. He 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 Suna-nin left, determined like Shira to prove themselves by finding more scrolls, Shira agreed to Lee's request to have a one-on-one battle.
