Naruto would be devastated. He's always been one to value his friends deeply. He might initially go into denial and then be filled with rage, vowing to find out who or what was responsible for her death and seek justice. He would also likely carry a great deal of guilt, thinking that he should have been able to prevent it.
Their friends' reactions would be quite diverse. For instance, Ino, who was once Sakura's rival, would have a mixed reaction. On one hand, she would be happy for Sakura as they have grown to be friends over the years. On the other hand, she might feel a bit envious. Choji would be excited and would look forward to all the feasts at the wedding. As for Lee, he would be over - the - moon for Naruto and Sakura. He would probably give them some long - winded and passionate speeches about love and friendship.
Kakashi would be more of a supportive figure. He has seen Naruto and Sakura grow up, and he would likely be happy for them. He might offer some advice to Naruto on how to handle this new relationship, especially considering the challenges they might face as ninjas. For Sakura, he could give her words of encouragement to be true to her feelings.
Sasuke might initially be a bit aloof but secretly be happy for them. He's always had a complex relationship with Naruto and Sakura, and deep down, he would see that they are good for each other.
Their friends would be overjoyed. Kakashi would probably be like a cool uncle, always ready with some wise advice for the new parents. Shikamaru might be a bit exasperated at Naruto's over - enthusiasm as a father, but still be happy for them. Ino would be excited to spoil the baby with cute outfits and toys, and Choji would bring over lots of delicious snacks for the new family to enjoy.
Sasuke would likely be very conflicted. On one hand, he has his own relationship with Naruto and Sakura. He might initially be angry at Naruto for attacking Sakura. But if he discovers the reasons behind it, he may understand Naruto's actions to some extent.
Iruka sensei would be very proud of Naruto. He has been like a father figure to Naruto, and seeing him get married to Sakura would make him feel like Naruto has truly grown up. As for the other villagers, most of them would be happy as Naruto is a hero. They would see Sakura as a great match for him, someone who can support him and also contribute to the village with her skills.
Sasuke would probably have a complex reaction. He might feel a bit of envy deep down but also be happy for them on the surface. Kakashi would be very supportive and would likely give them some sage advice about marriage, like how to always communicate and trust each other. Shikamaru would be like 'What a drag, but congratulations anyway' in his typical laid - back style.
Sasuke would probably be quite surprised. He might initially be a bit skeptical about Sakura's feelings, thinking it could be some sort of impulse. Shikamaru, being the perceptive one, would likely see the potential for chaos in this new development. He might try to stay out of it at first but keep an eye on how things unfold. Choji would be more focused on the emotional aspect and would hope that Naruto and Sakura can work things out happily.
She might be initially terrified. Sakura is a character who is used to a certain level of normalcy, so encountering ayakashi would be a huge shock. But as the story progresses, she could become more determined to face them. For example, if she realizes that her friends or loved ones are in danger because of the ayakashi, she'll find the courage to stand up to them.
