Iruka would be very supportive. He has always been like an older brother to Naruto, and he would see Kakashi as a great addition to Naruto's family. Shikamaru might raise an eyebrow at first, but then he would think it's a good thing for Naruto. He would probably say something like 'Well, as long as it makes Naruto less of a troublemaker.' Ino would be excited and might start to see Kakashi in a new light, as someone who can have a positive influence on Naruto. And the kids in the village would probably be really curious and might start to imitate Naruto, looking up to Kakashi as a sort of village father figure too.
Sasuke might be initially shocked. He's always been in a sort of competitive relationship with Naruto. But then he might see it as a sign of Naruto's growth and need for family. Sakura would probably be really happy for Naruto. She knows how much Naruto has yearned for a family, and she would see Kakashi as a great father figure for Naruto. As for the older generation like Tsunade, she might be a bit hesitant at first, but then she would support it, seeing that it gives Naruto more stability.
The other members of Team 7 would have different reactions. Sai, who is still learning about emotions, might not fully understand it at first but would gradually come to accept it. Yamato would see it as a positive development. He knows Kakashi's capabilities and how much Naruto needs someone like that in his life. The villagers, on the other hand, might be a bit divided. Some would be happy that Naruto has found a father - like figure in Kakashi, while others might be skeptical, thinking it's too soon or that Kakashi has his own secrets.
Well, Shikamaru would be one of the characters who would take Naruto's sacrifice very hard. He had always respected Naruto's determination. His reaction might be to become more serious about his duties in the village, feeling that he needs to step up in Naruto's absence. Hinata would be heartbroken too. She had deep feelings for Naruto. She might struggle to come to terms with his loss but also find strength in his selfless act. And all of the Konoha 11 would be united in their grief, vowing to protect the village and each other more fiercely in Naruto's memory.
The other villages might react with a mix of shock and suspicion. They knew Naruto was a powerful force for good in the ninja world. His death could be seen as a sign that something was amiss in Konoha. Some villages might even fear that Konoha was becoming unstable and could pose a threat. Characters like Gaara, who had a special bond with Naruto, would be deeply saddened and might try to find out the real reason behind Naruto's death.
The villagers of Konoha would be divided. Some would trust Kakashi and believe there was a good reason for Naruto's death, while others would be furious. The older generation, like Tsunade if she was still around, would demand an investigation. And for Hinata, she would be the most affected. She might feel like she lost her purpose in life with Naruto gone, but then find new strength in seeking justice for him.
Kakashi might be initially surprised. But then, he would probably use it as a teaching moment for Naruto. He could say something like 'Naruto, stealing is not the way of a ninja.' And then give him a punishment like extra training.
Kakashi would likely be very concerned. He would immediately assess Naruto's injuries. If they were serious, he would use his medical skills to start treating him right away. His first reaction would be to make sure Naruto was stable and out of immediate danger.
Naruto would be extremely devastated. He sees Kakashi as a mentor and father figure. He might go into a period of deep depression at first, but then turn his grief into motivation to become stronger. Sakura would also be very sad and might focus more on her medical skills, vowing to save more lives in Kakashi's memory. Sasuke might have a more internal reaction, feeling guilty if Kakashi died protecting him, and it could further fuel his own goals, whatever they may be at that time.
Well, in many fanfictions, characters like Sakura might immediately take on a more nurturing role. She could be seen gathering medical supplies and constantly checking on Naruto's condition. Kakashi, on the other hand, might show his concern in a more understated way. He could be by Naruto's side, offering quiet words of encouragement or just being there as a reassuring presence. Sasuke might initially seem aloof but could end up showing his care in his own unique way, perhaps by secretly training extra hard to protect the village while Naruto is sick.
He may be surprised. Fanfictions can have some really out - there ideas that he might not have considered before. For instance, a fanfiction might have Naruto suddenly having a new, super - powerful jutsu that was never seen in the original series.
He might be initially shocked. Since he sees himself as a good mentor, hearing such a harsh accusation from Naruto could leave him speechless for a moment.
He'd probably be a mix of angry and sad. Angry at whoever or whatever caused Naruto to be in this state, and sad because he cares about Naruto so much. He might clench his fists tightly, trying to control his emotions while he focuses on helping Naruto. He'd also feel a sense of guilt, wondering if he could have prevented this from happening.
