It could lead to some really interesting plot twists. Maybe Goku could prevent major disasters before they happen and change the course of events in the Dragon Ball universe.
They might be shocked and feel guilty. In the story, they could realize how much Naruto has endured alone. For example, Sasuke might have a complex mix of emotions, knowing Naruto has faced so many hardships while he was away.
Naruto's future - seeing ability could completely shift the power balance in the story. He could use it to find out where all the powerful artifacts or secret techniques are hidden in the future. For instance, if he saw the location of the Sage of Six Paths' hidden power, he could get there first and gain that power. This would put him in a much stronger position than his opponents, and might even change the political situation in the ninja world as different villages would react to his new - found strength.
Sakura is the central character. In addition, there could be a mysterious old woman who seems to know more about Sakura's power than she does herself. This old woman could be a guide of sorts, giving Sakura hints about how to control and understand her visions better. There might also be a rival character, perhaps a jealous classmate named Akiko, who tries to undermine Sakura because she's jealous of the attention Sakura gets due to her unique ability.
Well, they might see a future where they have a big family. Since Naruto always wanted to be acknowledged and have people around him, he could see himself surrounded by his children and Hinata in a happy home. And for Hinata, she might see herself as a strong kunoichi, still supporting Naruto in his Hokage duties.
Well, they could see the future through magical visions. Maybe a powerful sorcerer gives them a glimpse of what's to come. For example, they might see the rise of a new threat to Camelot or the discovery of a long - lost magical artifact that will change the fate of the kingdom.
Well, perhaps there could be a plot where Sakura sees the future of her own love life. She might see herself with someone unexpected, and then she has to navigate her current relationships and feelings while also trying to understand how this future might come to be. It could also be that she sees a future where her special ability is revealed to the whole world, and she has to deal with the consequences, like being hunted by those who want to use her power for their own gain.
Sasuke, on the other hand, might be more conflicted. He has his own goals and ideals. If he saw a future that didn't align with what he wanted, he might first question the vision. But ultimately, he could also take steps to change it, especially if it involved the safety of his village or his loved ones like Naruto or Sakura. He has a complex personality, so his reaction would not be straightforward.
The drawbacks could be significant. He may start to isolate himself because he knows things that others don't. This could lead to a breakdown in his relationships. And if the wrong people found out about his ability, they would surely try to use it for their own evil purposes. He would constantly have to be on guard against that. Another issue is that the future he sees might not be set in stone. If he made decisions based on what he saw, but then the future changed, it could lead to chaos.
Seeing the future could also add a new layer of excitement to their relationship. They might start planning for the things they saw, like having a certain number of children or living in a particular place. This shared vision of the future would give them common goals and dreams, which are essential for a long - lasting relationship.
