In a fanfiction where Naruko and Sasuke are married, it would affect the Naruto universe in many ways. Socially, it could break down some barriers between different clans. Since Naruko is from the Uzumaki clan and Sasuke from the Uchiha clan, their union would symbolize unity. This could lead to more inter - clan marriages in the future. In terms of the ninja world, their combined strength would be a major deterrent to any potential threats. And they could start a new ninja academy together, with a curriculum that focuses on both physical and emotional strength.
Their relationship could have a huge impact. Itachi is a highly respected and feared shinobi. His marriage to Naruko, who is also quite well - known, would likely change the power dynamics. Other villages might view Konoha as even more powerful and unpredictable. Also, within the village, it could lead to new training methods as they combine their skills. For example, Itachi's genjutsu skills and Naruko's unique chakra control could create a new form of combat training.
It would definitely shock their friends. Naruto, for instance, would be caught in a difficult position as he is a close friend to both. He would probably try to mediate but might not be successful.
Naruko would likely become more mellow. With Sasuke by her side, she wouldn't feel the need to constantly prove herself as much. She might focus more on building a family and using her skills for the betterment of the village. Sasuke, on the other hand, would open up more. His cold exterior would soften as he experiences the warmth of a loving relationship. He would also become more involved in the village's affairs, not just for atonement but because it's now his home with Naruko.
For Hinata, it would be a dream come true. Her relationship with Naruto would take a huge step forward. She would likely be overjoyed and more confident. Naruto, on the other hand, might face some mixed reactions from his friends. Some might be surprised but supportive, while others might question this sudden shift. Sasuke would probably be a bit confused at first. His relationship with Naruto has always been unique, and this change could make him wonder about his place in Naruto's life.
The Uzumaki family might be a bit shocked at first. But Naruto's kind - hearted nature could make them eventually come around. His mother Kushina might be more accepting as she always wanted Naruto to be happy. As for Sasuke's family, well, it's a bit more complicated. Since Sasuke is the last of the Uchiha, his family's traditional values might be a hurdle. However, if Sasuke is determined, he might be able to convince any remaining family members or those who care about the Uchiha legacy that his relationship with Naruto is a positive thing.
If Naruto and Kin were married in a fanfiction, it would likely create new alliances. Kin has knowledge of the Akatsuki. This knowledge could be used to prevent future attacks on the Leaf. Also, Naruto's influence might change Kin further, leading to a different kind of character development for her which would then affect the overall plot.
It can completely change the storyline. If Sasuke travels back, he can make different choices that alter the fates of many characters. For Naruko, it could mean she has a stronger ally earlier on. For example, if he goes back to their academy days, he could support her against the bullies, which would boost her confidence and change her development path. This would also affect how she approaches her ninja training and her goals.
It could change the dynamics between the characters. For example, it might make Asuma a bit jealous if he were still alive, creating some tension. Also, Naruto's friends might be a bit surprised at first but then support him. It could also lead to new alliances as Kurenai's friends and family might be more inclined to support Naruto in his future endeavors.
In a Naruto Neglected God Summon Fanfiction, the Naruto universe would face several consequences. The neglected god summon might start to influence the world in negative ways out of spite. It could start to corrupt the minds of some ninjas, making them more power - hungry and ruthless. This would then spread like a disease, causing a breakdown in the moral fabric of the ninja world. Additionally, the balance between the different elemental forces in the universe could be thrown off. Since the god summon may have had a unique connection to the elements, its neglect could lead to elemental imbalances, resulting in things like droughts or floods in different regions.
It could change the relationships Naruto has with other characters. For example, his friends might be shocked at first but then become protective of his daughter. His enemies could see her as a new target or a way to get to Naruto.
