In the fanfiction, Naruto could develop her skills in a different way. Instead of just focusing on combat, she might start to learn more about healing and support, to be a better partner for Sasuke. Sasuke would develop his sense of loyalty not just to the village but to Naruto on a whole new level. He would be more protective of her, and this would lead to him becoming more involved in the community to ensure their safety. Their relationship would be a catalyst for each other's growth, both as individuals and as part of the village.
Naruto would develop in terms of her emotional intelligence. Since she has always been a bit of a hot - headed character, being married to Sasuke would force her to think more before acting. She would become more patient. Sasuke would start to open up more about his past traumas, which he has always kept bottled up. This would not only help their relationship but also his own personal growth. He would also start to interact more with the village, something he avoided in the past, all thanks to Naruto's influence.
For Naruto, as a female, she might become more confident in her femininity while still maintaining her strong ninja spirit. She would grow in her ability to understand Sasuke on a deeper level. Sasuke, on the other hand, would become more empathetic. His cold exterior would soften as he is influenced by Naruto's warmth. He would also learn to be more domestic, sharing responsibilities in their relationship.
In this fanfiction, Naruto could develop a new set of skills related to childcare. He would learn how to make baby Sasuke happy, feed him, and put him to sleep. Sasuke, on the other hand, could start to see Naruto as a true brother figure from a very young age, which would shape his personality and relationships in the future.
For Naruto, he would have to grapple with the fact that he is fighting his former friend. This could make him more solemn and determined. He might develop a darker side as he realizes the seriousness of stopping Sasuke. For Sasuke, he could start as overconfident in his power but as Naruto keeps pushing him back, he could become more desperate and start to question his own motives.
One possible plot twist could be that they face opposition from their respective clans who still hold grudges from the past. The Uchiha clan might not accept Naruto easily due to his connection to the Nine - Tails. Another twist could be that Sasuke discovers a new power within herself during their marriage that has unforeseen consequences for the village. Maybe it attracts enemies who want to steal that power.
The plot could involve a post - war scenario where the village is rebuilding. Sasuke and Female Naruto's relationship blossoms during this time. Their marriage could be a symbol of hope for the village. Maybe there are some who oppose the union at first because of Sasuke's past actions. However, Naruto stands by him and they prove to everyone that their love is real and strong. They might also have to deal with political issues within the village as a married couple, but they use their influence to bring positive change.
For Naruto, running away might make him more determined to prove his worth and protect his friends. He could learn to control his Nine - Tails chakra better in the face of danger outside the village. Sasuke may start to trust Naruto and Sakura more, realizing that they are his true comrades. Sakura, on the other hand, could become more independent and confident in her abilities, not just relying on Sasuke and Naruto but also being able to take charge when needed.
For Naruto, he might become more determined to bring Sasuke back to the right path. The fight in the bathroom could be a turning point where he realizes that he can't just use words but also has to show his strength. Sasuke, on the other hand, could start to question his own motives a bit more. Maybe seeing Naruto's unwavering spirit in such a strange setting makes him think twice about his actions.
For Itachi, he could become more open and less brooding. Hinata's love and support might make him feel like he can finally let go of some of his past burdens. For Hinata, she could gain more confidence in herself. Being with Itachi, who is highly skilled, gives her the motivation to train harder and become a stronger ninja. Also, she might become more assertive in dealing with clan matters, especially when it comes to any opposition to their relationship.
In some fanfictions, their marriage could be a political move at first. Maybe the Hidden Leaf Village needs to strengthen its alliances, and a union between Sakura, a strong kunoichi, and Sasuke, a powerful shinobi, seems like a good idea. But as they spend time together, they start to develop real feelings for each other. They have to deal with the gossip and doubts of the villagers, but in the end, they prove that their love is real.
Another interesting development could be both of them learning from each other's strengths. Sasuke could learn the value of having strong bonds from Naruto, while Naruto could gain a better understanding of the power of self - reliance from Sasuke. This mutual learning could change their characters and their relationship in the fanfiction.
Sasuke's character would likely become more complex. His act of killing Danzo could push him further into the realm of darkness or, paradoxically, start his journey towards redemption as he realizes the full weight of his actions. Danzo's character, in death, could be revealed in different lights. Maybe his true motives for his actions throughout his life are uncovered, which could affect how other characters view Sasuke's killing of him.
