One possible plot could be that Naruto gains Shisui's eyes through some mysterious ninja art. With these eyes, he could have enhanced perception abilities, like being able to see through genjutsu more easily. This would change his fighting style and make him even more formidable against opponents. He might also use the unique powers of Shisui's eyes to uncover hidden secrets in the ninja world, leading to new adventures and alliances.
In fanfiction, Naruto getting Shisui's eye could lead to a whole new plotline. It could potentially be a way to bridge the gap between the Uchiha clan and Naruto. Since Shisui was an important Uchiha, having his eye might give Naruto a connection to the clan's history and secrets. This could play a role in resolving some of the long - standing issues between the Uchiha and the rest of the village. Naruto might also use the eye's powers in unique ways, like combining it with his own Uzumaki chakra, creating new and unexpected jutsu.
Well, they'd probably have a lot of fun. Naruto's energetic nature would liven up their living space. They could have friendly competitions like who can clean the room the fastest or who can cook the best ramen. And at night, they might sit and tell stories about their adventures, with Shisui sharing some of the more secretive missions he's been on in the village.
I really like 'Shisui's Love for Fem Naruto'. It starts with a chance encounter between them. The author does a good job of developing their relationship slowly. Shisui starts to notice the little things about Fem Naruto that make her special. There are parts where they train together and share their dreams, which builds a solid foundation for their romantic relationship.
In this scenario, Naruto being Shisui's brother would mean he might have grown up with a different kind of training. Shisui was highly skilled in the ways of the ninja. Naruto could have learned some of his stealth and combat techniques at an earlier age. This would make him an even more formidable opponent. Moreover, it could have an impact on the Akatsuki's plans. They were after the Sharingan, and if Naruto was related to Shisui, they might target him differently. It could also change the way the village of Konoha views Naruto. He would have a stronger connection to the Uchiha, which could either make them more suspicious of him or more protective, depending on how the story unfolds.
It could make Kakashi more protective of Naruto. Since Kakashi is well - aware of the power of Shisui's eyes, he would know the potential danger Naruto is in. He might train Naruto more intensively to help him control the eyes and also protect him from those who would seek to take the eyes for themselves.
Naruto's character would likely become more serious and focused. Training with Shisui and the Sharingan would demand a lot of concentration, so he'd have to tone down his wilder side. He might also become more strategic in combat, as the Sharingan gives insights into opponents' moves.
Another ability Naruto could gain is a deeper understanding of genjutsu. Shisui was very proficient in genjutsu, especially with his Sharingan. Naruto, being his brother, could have a natural aptitude for genjutsu. He could learn to break through stronger genjutsu more easily and also use more advanced genjutsu himself. This would be a significant change as Naruto was not originally known for his genjutsu skills, but with this new connection, he could become a more well - rounded ninja.
One possible plot could be that Ino is in a situation where she needs to quickly gain Shisui's attention or stop him from doing something. Straddling him might be a very bold move on her part in the heat of the moment. Maybe they are in the middle of a battle or a dangerous situation where she uses this tactic as a last - ditch effort to communicate or make him listen.
In this fanfiction, a really interesting plot twist could be that the training by Shisui actually awakens a dormant power within Naruto that has nothing to do with the Sharingan at first glance. As Naruto delves deeper into the Sharingan training, he starts to notice connections between this new power and the Sharingan. Maybe it's a power related to the Sage of Six Paths that gets activated in a unique way due to the Sharingan training. Also, the relationship between Naruto and Shisui could take an unexpected turn. Instead of just a teacher - student relationship, they could become something like comrades with a shared mission that is revealed during the training process.
