His sister might act as a mediator between Naruto and Sasuke. When they have their fall - outs, she could be the one to try and patch things up. She might see the potential in both of them and want them to work together for the good of the village.
Well, Naruto's sister could have a different view of Sasuke compared to Naruto. Maybe she sees Sasuke's pain and the darkness in him more clearly because she's older and more perceptive. This could lead to her trying to get Naruto to understand Sasuke better, which in turn would change the dynamic of their relationship. For example, she might encourage Naruto to be more patient with Sasuke when he goes on his revenge - seeking path.
If Sasuke's sister was in the picture, Naruto and Sasuke's relationship might soften more quickly. Naruto would see another side of Sasuke through his sister. He might also feel more of a connection to Sasuke's family. Sasuke, on the other hand, would see Naruto's genuine care for his sister, which could make him trust Naruto more.
Well, their relationship as siblings would be more of a family - based bond. Unlike with his friends, Naruto and Lemon would have a shared family history and a deeper sense of loyalty that comes from being family. With friends, Naruto has a sense of camaraderie, but with his sister, there's a more innate connection.
Well, if Naruto has a twin sister, she might be more understanding towards Sasuke's pain. Unlike Naruto who sometimes challenges Sasuke head - on, she could approach him in a more empathetic way. Maybe she would be the one to first notice the changes in Sasuke after Itachi's visit and try to console him. This could lead to a different dynamic between Sasuke and the Uzumaki siblings, with Sasuke being more open to her than to Naruto at times.
The relationship would be more trusting from the start. Since they are brothers, Sasuke might not be as quick to envy Naruto's progress. Naruto would also be more protective of Sasuke and vice versa. They would probably share their secrets more openly and train together more often.
In fanfiction, their relationship can be complex. The older sister might act as a protector for Sasuke. For example, she could shield him from the darker aspects of the ninja world when he was young. This would create a deep sense of trust between them.
It would be more nurturing. Kurenai could cook for Naruto, like making him some of her special ninja - style meals. And she'd be there to listen to his problems, whether it's about his love life or his struggles with mastering new jutsu. Their relationship would be based on mutual trust and respect, just like a real sister - brother relationship.
If Naruto has a sister in the fanfiction, Sasuke might see her as another connection to Naruto. He could initially be suspicious of her, thinking she might be a liability to Naruto. But as time goes on, if she proves herself to be strong, Sasuke might respect her. Their relationship could also be a source of some jealousy for Sasuke, as Naruto might spend more time with his sister.
Their relationship could develop through mentorship. Naruto, being older, could offer guidance to Sasuke. Sasuke would look up to Naruto as a strong and experienced ninja.
His life would be more protected. The older sister could be very overprotective. For instance, when it comes to Quidditch, she might not let him play at first because she's worried about him getting hurt. But on the positive side, she could also introduce him to some really cool wizarding families. Harry would also have someone to share his secrets with, like his feelings about Snape or his fears about Voldemort. They could work together to figure out the mysteries of the wizarding world, like the secrets of the Chamber of Secrets.
If they had different sensei, their relationship could become more competitive. For example, if Sakura's sensei focused on making her a top - tier medical ninja quickly and Naruto's sensei was pushing him to master new powerful jutsu, they might compete to prove who is more valuable to the village.
