Naruto may initially be hurt both physically and emotionally. However, he'll soon realize that there must be a reason behind Karui's actions. He'll start thinking about how he can resolve the situation. Given his growth throughout the series, he won't simply retaliate. He'll try to understand Karui's perspective, whether it's related to her village's concerns or something personal. And he'll do his best to find a solution that benefits everyone, showing his selfless and positive nature.
He might be confused at first. Naruto is used to being attacked by enemies, but Karui is an ally. So he would wonder what went wrong.
He might be in shock at first. Mike could just sit there, trying to process what has happened. Then, he would probably be angry. He's not the type to just let things go, so he'd start thinking about who could be behind it and how to get revenge.
One possibility is that there's a misunderstanding between Naruto and Karui. Maybe Karui thinks Naruto has something to do with Sasuke's actions that have affected her village. So, in her anger, she attacks Naruto.
Naruto might be shocked at first. He has always seen Sakura as a friend, so being beaten up by her would be unexpected. He could try to talk to her and figure out what's wrong.
Sakura might be a bit surprised at first, but she would probably come around and be happy for Naruto. Sasuke would likely be indifferent on the surface but secretly hope that Naruto is making the right choice. Hinata might be a bit sad that Naruto didn't choose her, but she would be polite and congratulate them.
Sakura might be initially shocked and a bit jealous, but she would probably come around to support Naruto as a friend. Kakashi would be more of a calm and collected figure, offering advice on how to handle the situation both as a ninja and as an expecting father. Sasuke, on the other hand, might be indifferent at first but later show some concern for Naruto's well - being in this new situation.
Sakura might be a bit surprised at first. She has always seen Naruto as a friend, but she would quickly come to support him. She knows how much Naruto values his relationships, and if he has found love with Gaara, she would be happy for him. Kakashi would be very accepting. He has always believed in Naruto's judgment and would see this as another step in Naruto's journey to change the ninja world. Shikamaru would probably be the one to think about all the political implications but in the end, he would also support it as he trusts Naruto.
Some people might immediately side with the girl, especially if they find out the boy was in the wrong first. For example, if he was the one who started the trouble by being aggressive.
Well, Naruto's friends would be excited for him. They know how much he has longed for a family of his own. As for the Yamanaka family, they would be proud that Ino has found someone as heroic as Naruto. His reputation as a savior of the ninja world would play a part in their acceptance. And Naruto, who has always craved family, would be welcomed into the Yamanaka family with open arms after some getting - to - know - you time.
Sasuke would likely be conflicted. On one hand, he has his own issues with Konoha, but on the other, he might be surprised that Naruto, who was always so loyal, would give up. He could try to understand Naruto's reasons or maybe even join him depending on the situation.
Their relationship could develop through shared experiences. For example, if they both participate in a big battle against a common enemy. They protect each other during the fight, which makes them see each other in a new light.
