The reaction would be overwhelmingly negative. Naruto fans come from all ages and backgrounds, but a common thread among them is the appreciation for the positive values the series represents. A plot like this would be considered not only immoral but also a desecration of the beloved characters. Some fans might even feel that it's a form of trolling or an attempt to shock for no good reason. It could lead to a lot of criticism and a push to keep such content away from the mainstream Naruto fan areas.
This is a very disturbing and unethical concept. Incestuous relationships are not acceptable in society and violate basic moral principles. In the context of Naruto, which is a popular and family - friendly franchise, such a plot would go against the positive values it usually promotes.
At first, the relationship might be strained. Naruto could be jealous of his sister's favored status. However, as the story progresses, his sister might start to see the injustice Naruto faces and try to bridge the gap. They could gradually develop a more understanding and loving relationship.
His friends would be really happy. Shikamaru would probably be like 'Well, it was bound to happen eventually, Naruto.' and offer some practical advice. Choji might bring over some delicious food for Hinata to help with her pregnancy cravings. Kiba would probably joke around with Naruto about how his life is really changing now.
Sakura would probably be very shocked and disappointed in Naruto. She has always had deep feelings for him. Kakashi might be more level - headed, trying to figure out how to handle the situation from a strategic and diplomatic point of view.
Sakura might be initially shocked and a bit disappointed. She has had feelings for Naruto in the original story, so this news would be hard for her to take. Sasuke would probably be more stoic on the outside but might be secretly concerned about how this would affect Naruto's ninja abilities. Shikamaru would likely be the one to think about all the long - term implications and try to come up with a plan to help Naruto deal with the situation.
Sakura would likely be shocked at first. She might feel a bit of jealousy or disappointment as she had some feelings for Naruto in the original story. But being a medical ninja, she would probably also offer her help to Blackfire during the pregnancy. Kakashi would be more composed. He would probably give Naruto some advice on responsibility and how to handle the situation with all the political and social implications. Sasuke might be indifferent on the surface but secretly be a bit worried about how this would affect Naruto's standing in the ninja world.
The ninja community's reaction would be quite mixed. Some, like Naruto's close friends such as Shikamaru and Kakashi, would be supportive. They would likely offer their protection and assistance to Naruto during his pregnancy. However, there would also be those who are more traditional and might view Naruto's pregnancy as a weakness or something that goes against the norms of the ninja world. They could try to isolate Naruto or even oppose Sasuke's relationship with him because of it.
They could start by having some friendly competitions. For example, in a race to the top of a mountain or a sparring match. This would not only show their bond but also their competitive nature as siblings.
In the long run, Naruto might try to find a way to redeem those who cheated on him. Despite the pain, his kind heart would still hope for the best. He would likely try to understand their motives and see if there's a way to fix the broken relationships, while also being more cautious and less trusting in the future.
Naruto might be initially shocked and heartbroken. He is someone who values loyalty and friendship deeply, so being cheated on would be a huge blow to him.
