Well, the story might progress as they try to blend in with their younger selves' lives. Naruto would still be the go - lucky guy, but with a more serious undertone because he knows what's coming. Hinata would be more confident perhaps. They could start to change things like the way ninjas are trained in the village. They might introduce new techniques they learned in the future.
In a fanfic where Naruto and Hinata are sent back in time, the story could progress in many ways. At first, they would likely be shocked and confused. But then they would realize the potential of their situation. Naruto could use his future knowledge to help his friends, like Sasuke, avoid certain paths. Hinata could use her knowledge of medical ninjutsu from the future to improve the village's healthcare. As they interact with the past characters, they would slowly but surely change the future of the Naruto world. Their relationship would also be a big part of the story, as they navigate their feelings in this new timeline.
In such a fanfic, Naruto and Hinata getting sent back in time could lead to some really interesting relationship developments. They could start their relationship much earlier, and since they already know each other well from the future, they might have a deeper connection right from the start. Also, they could use their knowledge of future events to gain allies more easily.
Her gender can affect the story in several ways. For one, she might face different expectations from the characters in the past. In the Naruto world, gender roles do exist, and as a female Naruto, she may have to fight against some traditional ideas. For example, some might not believe she can be as strong as a male ninja. Also, her relationships with male characters could be different. Romantic interests might develop in new ways or face more obstacles due to her gender. Maybe some male characters are more protective of her than they would be if she were male, which could both help and hinder her in her adventures.
The story could also take a turn where Tayuya actually has a change of heart before she even tries to attack Naruto. She could learn something about Naruto that makes her realize he's not the enemy she thought he was. For example, she might find out about his difficult past and how he overcame it, and this could make her reluctant to carry out the kill order.
One possible reason could be to correct some mistakes in the future. Maybe there were some events that led to a really bad outcome, like the destruction of the Hidden Leaf Village, and Kami thought sending Naruto back in time could prevent it. Another reason might be to give Naruto a chance to learn more about his predecessors and gain new powers or knowledge that could help him in his original timeline.
The story could progress with the village trying to subdue Naruto. They might call on all their strongest ninja, like Kakashi or even the Hokage. Meanwhile, Naruto could be on a rampage, causing destruction everywhere.
In this fanfiction, once Orochimaru kidnaps Hinata, the story might start with Hinata waking up in a strange, dark place. She'd be scared but also resolute. As she tries to assess her situation, Orochimaru would likely make an appearance and start taunting her. Meanwhile, outside, Naruto and his friends would be following any leads they can find. They might run into some of Orochimaru's old allies or enemies who could either help or hinder their search. The story could also focus on Hinata's internal struggle as she battles her fears and tries to find the strength within herself to survive and escape. And when the rescue party finally arrives, there could be an epic battle between Orochimaru and the Leaf Village ninjas with Hinata's fate hanging in the balance.
One great 'Percy sent back in time' fanfic is 'Back to the Beginning'. It shows Percy having to deal with all the early threats in a new way. Another is 'Time - Twisted Percy' which has an interesting take on how his knowledge of the future changes things. There's also 'Percy's Time - Travel Adventure' where he forms unexpected alliances in the past.
One common plot twist could be that the female Naruto discovers she has a hidden power that was dormant in her original timeline but is awakened in the past. For example, she might find out she has a special connection to an ancient jutsu or a long - lost clan. Another plot twist could be that her actions in the past change the future in unexpected ways. Maybe she accidentally prevents the birth of one of her important friends in the original timeline. Or perhaps she gets caught up in a political intrigue that was not part of her original story and has to navigate through it carefully to ensure she can still return to her own time and that the future she knows is not completely altered.
Well, in this type of fanfiction, Naruto could change the relationships he had at the academy. He may befriend Sasuke earlier and in a different way, perhaps preventing Sasuke from being so cold towards him initially. Also, he could have more time to train with his classmates and help them improve too, which would make for a very different dynamic in the group.
Here's another story. A group of paratroopers were sent back during a mission. Their plane had mechanical problems. Once sent back, they were redeployed to a different theater of war. They had to quickly adapt to new strategies and fight alongside different units, which was a huge challenge but also an opportunity to learn new combat techniques.
