Overall, they would likely band together even more tightly. They've been through a lot together already, and seeing the future would be another big thing that unites them. They'd share their thoughts and feelings about what they saw, and then start taking steps to either prevent a bad future or work towards a good one. Naruto would be the driving force, inspiring everyone with his unwavering belief in a better tomorrow, while his friends would bring their unique skills and perspectives to the table.
Naruto would probably be very excited and want to immediately start making changes for the better. He has always been about hope and improvement.
Sasuke might be more skeptical at first. He'd analyze the situation carefully before deciding on a course of action. But once he's convinced, he'd be fully committed. Sakura would be worried but also determined to help. She'd use her medical skills and her strength to support Naruto and Sasuke in whatever they plan to do to change the future. Their other friends like Shikamaru would come up with clever strategies to deal with the challenges shown in the future they saw.
Naruto might react with a sense of responsibility. If he saw a future where Konoha was in danger, he would feel it was his duty to do something about it. He could start by gathering information from the future vision, like the weaknesses of the enemy. Then, he would share this knowledge with his comrades and come up with a plan to protect the village.
The older characters such as Kakashi would be cautious. They would recognize Naruto but also be worried about the implications of someone from the future being in the present. They would want to know if his presence could change the future in a negative way. For example, they might fear that his actions could lead to the earlier awakening of a powerful enemy. As for the villains, they might see future Naruto as a threat and try to eliminate him as soon as possible. Orochimaru, for instance, would be very interested in Naruto's future powers and might try to capture him to study. And the new generation of ninja in the past would look up to future Naruto, seeing him as a symbol of what they could become.
Minati could be deeply saddened. If he has been following Naruto's journey, seeing him die would be like losing a friend. He might shed some tears and feel a sense of emptiness. He may also feel angry towards the circumstances or the character responsible for Naruto's death.
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.
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.
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.
Naruto would likely be excited yet a bit scared. He'd be eager to make the future a better place but also worried about the bad things he might see. Sasuke would probably be more reserved, analyzing the future information carefully. Hinata would be shy about it but also determined to protect those she loves if she saw any danger in the future for them.
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.
In fanfic, the Naruto Orb's future - seeing ability can be portrayed in various ways. It could show hazy visions that are open to interpretation, like a blurry image of a battle with only a few recognizable elements. This makes the characters have to work hard to figure out what the vision means.
