It could be quite challenging for them. Without Naruto's unique skills and strategies, they might have to rely more on their own teamwork and individual strengths.
Maybe he realizes the exam is too dangerous or he discovers some unfairness in it. In the original Naruto story, Naruto has faced many difficulties and moral dilemmas during the Chunin Exam. So in the fanfiction, similar situations might push him to quit.
One possible scenario could be that Sasuke returns just in time to see Sarada's skills in the Chunin exam. He might be filled with pride as he watches her fight. Sarada, on the other hand, would be motivated to show her father what she has learned. It could also be a moment of emotional reunion, especially if they haven't seen each other for a while.
After meeting in the Chunin exam, their relationship could become stronger. Sarada might start to train more rigorously with Sasuke, eager to learn from him. Sasuke could become more involved in her life, guiding her not just in ninja skills but also in understanding the ninja world better.
One possible fanfiction could be about Sakura showing off her improved medical ninjutsu skills during the Chunin Exam. She might use her skills to quickly heal her teammates during battles, surprising everyone with her growth.
He might face disappointment from his friends and mentors. His friends who were also participating in the exam might feel let down, and his mentors, like Kakashi, could be concerned about his decision and how it will affect his future as a ninja.
One possible fanfic could be about Naruto and Temari teaming up during the Chunin Exam in unexpected ways. Maybe Naruto helps Temari when she's in a tough situation against an opponent she underestimated. They could form an alliance that surprises everyone.
Naruto would likely become more self - reliant. As a ronin, he doesn't have the support of a village. So during the Chunin Exam, he has to trust his own instincts and skills more. He may also become more cautious as he realizes he can't always count on backup.
In a fanfic, on Chunin Exam Day, there could be intense battles. Young ninjas might show off their new and improved jutsu. There could be unexpected alliances formed between rival teams as they face a common and tough enemy. Also, there might be some back - story revelations about the characters, like their hidden motives or past traumas that drive them during the exam.
Typically, the young ninja trainees like Naruto, Sasuke, and Sakura could be the protagonists on Chunin Exam Day in a fanfic. They are the main characters in the original series and are likely to play important roles in any fan - created story about the exam.
