His friends like Kakashi would be cautious yet supportive. Kakashi would likely give Naruto advice on how to handle the relationship and the responsibilities that come with it. In Kirigakure, Mei's comrades might initially be distrustful of Naruto, but as they see his good intentions and how he treats Mei, they would gradually accept him. And Naruto's friends from other villages he has befriended over the years would see it as a positive step towards a more unified ninja world.
Naruto's younger friends like Boruto and his gang would be really excited. They would see it as a cool and romantic story. They might even look up to Naruto more. For Mei, her friends who are more traditional might take some time to get used to the idea. But the younger generation in Kirigakure would be inspired by their love story and see it as a way to break old barriers between villages.
Shikamaru, being the smart and observant one, would analyze the situation thoroughly. He would probably warn Naruto about the potential political pitfalls and how to navigate them. He might also offer some strategic advice on how to handle the relationship aspect, like how to communicate effectively with his new partner in the political marriage so that Naruto doesn't get caught up in unnecessary drama or power plays.
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 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.
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.
At first, Naruto might be in shock. He has always trusted his friends, so the sudden betrayal would be a huge blow. He could be silent, unable to process what has just happened.
Sakura might be really surprised at first. She could offer to help Naruto with his girl disguise, teaching him things like how to do his hair or choose the right clothes. She might also find it a bit funny but would be supportive in the end, seeing it as part of a mission. Sasuke, on the other hand, might be a bit more aloof. He would probably just raise an eyebrow at Naruto's new look but wouldn't make a big fuss about it as long as it was for a good reason.
His friends would most likely rally around him. Kiba might use his dog Akamaru to scout the area and make sure there are no other immediate threats. Hinata would be really worried and would try to use her Byakugan to see if there are any hidden enemies or if Naruto has any internal injuries. Choji would offer some of his food to Naruto to give him strength, as his clan's food can have special effects on a ninja's body.
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.
As for Shikamaru, he would probably find the whole situation too troublesome. He might avoid 'female Naruto' at first, but then when he realizes it's really Naruto, he would start to give advice on how to handle the situation in the most efficient way, like how to avoid unwanted attention from other guys.
His other friends like Shikamaru would be in shock. Shikamaru, who is usually calm and collected, would struggle to come to terms with Naruto's death. They would all have to deal with the loss of the village's hero and a great friend, and it would likely change the dynamics of the entire group.
