Maybe the author wants to explore more of Naruto's growth at the genin level. There could be many untold stories and character developments that can happen during this stage. It gives the author more space to show Naruto's relationships with his friends, like Sasuke and Sakura, in a different light while still being a genin.
The fact that Sasuke is such a complex character as a genin makes these fanfics interesting. He has a lot of inner turmoil, like his desire for revenge against Itachi. Fanfics can explore this aspect in more detail.
Sure. There are many Genin Sasuke fanfics out there. You can start by looking on fanfic websites like FanFiction.net or Archive of Our Own. Just search for 'Genin Sasuke' and you'll find a variety of stories that explore different aspects of his character during his genin days, such as his training, his relationships with his teammates, and his growing power.
One consequence could be that he might face more discrimination from the village elders. In the original story, as Naruto advanced in rank, he gained more respect. But as a genin here, he could still be seen as a troublemaker. Another consequence is that his training might be different. He might focus more on basic genin - level skills, which could make him even stronger in the long run as he masters them to a higher degree.
I'm sorry, but 'lemon' in fanfiction often refers to adult or inappropriate content, so I can't recommend such fanfictions. However, there are many great Sasuke and Sakura Genin - themed normal fanfictions out there. You can try looking on platforms like FanFiction.net and search for non - inappropriate stories about their Genin days.
One plot idea could be a mission where Naruto and Sasuke have to protect a valuable village relic. They start off bickering as usual but gradually learn to work together better. Another could be a training session with their sensei where they compete in a unique way that tests their skills and friendship. Maybe a mystery in the village that only they can solve as they are the most talented genin at the time.
In some fanfictions, their relationship might be more amicable from the start. Instead of the initial rivalry and Sasuke's aloofness, they could be shown as fast friends who support each other right away. For example, Sasuke might be more open about his admiration for Naruto's determination early on.
There could be a character who has a disability in the ninja world, like being partially blind but having an amazing sense of hearing or smell. Naruto would see their potential and include them in the team. Another member could be a former criminal's child who is trying to make a name for themselves in a positive way. And there could be a super - intelligent ninja who is great at strategy but lacks in practical combat experience, and Naruto would help them gain that experience.
Another jutsu they might learn is the Summoning Jutsu. Naruto has a strong connection with the toads. He could teach the genin how to form the necessary hand seals and make a contract with a suitable summon. This would give the genin an extra edge in battles, being able to call upon a powerful ally.
The appeal lies in the characters. Naruto is a well - loved character with his boisterous and determined personality. Hinata is shy yet strong in her own way. Their dynamic at the Genin stage can be very captivating. Fans might enjoy seeing how Naruto's energy affects Hinata and how she slowly comes out of her shell around him.
