Sasuke might not care much at first, but if he sees that Naruto is actually considering it, he might become a bit protective. He knows Naruto's importance to the village and might worry that this relationship could be a distraction for Naruto from his duties.
The elders of the Hidden Leaf Village would have mixed reactions. Some might see it as a good way to strengthen the Hyuga clan's connection to Naruto, who is a hero. Others might be against it because they have different plans for Naruto's future, like political marriages with other villages.
Hinata would probably be very shocked at first. Since she has feelings for Naruto as well, she might feel a bit betrayed but also happy for her sister. She would be in a very conflicted state.
Sakura would probably be quite shocked at first. She has had feelings for Sasuke for a long time, so seeing him want to marry Fem Naruto would be a big blow. Naruto himself (in his male form in the story's context) would likely be supportive as he values Sasuke as a friend and would want him to be happy. Kakashi would be more of a neutral observer, but would also ensure that the relationship doesn't cause any unrest in the village.
The Hyuga clan members would be very confused by 'Hanabi' (really Naruto). They would notice her (his) un - Hyuga - like behavior and attitude. For example, Naruto's loud and friendly nature would be a stark contrast to Hanabi's more reserved Hyuga self. As for Naruto's friends, they would be puzzled by 'Naruto' (actually Hanabi). They would wonder why he (she) seems a bit different in combat and decision - making.
The older generation of shinobi like Tsunade would be both proud and a bit worried. Proud because it's a new step for the village but worried about the potential challenges that Sakura and Naruto would face. She might offer her medical expertise to ensure a healthy pregnancy. Shikamaru would probably be the voice of reason among Naruto's friends. He would help them think through all the practical aspects of having a baby, like housing, finances, and how it would affect their ninja duties.
Naruto would probably be extremely confused at first. He has always seen Itachi as a complex figure, and suddenly being forced to marry him would be a huge shock. He might feel angry that he has no say in this. Itachi, on the other hand, would likely be stoic on the surface but internally be very conflicted. He has his own burdens and this unexpected situation would add to them.
One possible plot twist could be that Naruto is initially in love with someone else, like Sakura. Hanabi's attempts to win him over could lead to some interesting rivalries and misunderstandings. For example, Sakura might see Hanabi as a threat and try to sabotage her efforts, creating drama.
Hinata might be a bit surprised at first. Since she also has feelings for Naruto, she could feel a bit of jealousy. But being the kind person she is, she would probably try to be understanding and not let it affect her friendship with Hanabi.
Harry would probably be very confused at first. He knows Hermione is usually a rule - follower, so her wanting to be punished would seem out of the ordinary. He might try to talk her out of it, thinking there must be some misunderstanding. Ron, on the other hand, would be more straightforward. He'd likely say something like 'Hermione, you're mad!' and try to convince her that she doesn't deserve any punishment. The teachers, such as Professor McGonagall, would be taken aback as well. She would probably question Hermione carefully to understand her motives before deciding on any action.
Sasuke might be conflicted. He has his own complex relationship with Naruto. Part of him might understand Naruto's reasons for leaving, but he could also be angry that Naruto didn't confide in him. Sakura would be worried sick. She has always cared about Naruto, and his leaving would leave a big hole in the team. Kakashi, on the other hand, would be disappointed but also respect Naruto's decision if he thought it was for a noble cause.
Iruka - sensei would be very concerned. He's always been like a father figure to Naruto. He'd probably spend a lot of time with Naruto, sharing stories from Naruto's past when he was brave and encouraging him to find that courage again. Kakashi - sensei would be more analytical. He'd observe Naruto closely, trying to figure out if this is a mental block or something more sinister. And the other villagers might start to lose faith in Naruto as their hero, which would add more pressure on Naruto to overcome his fears.
Sakura would be heartbroken. She's always had feelings for Naruto, and seeing him insane would be a huge shock. She'd likely try to use her medical skills to find a cure for whatever is ailing Naruto's mind. She might also try to get help from Tsunade, hoping that the former Hokage's knowledge could save Naruto.
