Another option is a jealous individual from Sakura's own time who somehow manages to follow her into the past. This person is envious of Sakura and wants to take over her role in the past - time events. They would constantly try to undermine Sakura and take credit for her actions, causing a lot of trouble for her during her time - traveling adventure.
One idea could be that Sakura goes back in time and accidentally changes a small event that has huge ramifications for the future. For example, she might prevent a key friendship from forming, and then has to figure out how to fix it before she returns to her own time.
In the past, Sakura could meet the original creators of the magic system she uses. They might be able to teach her things that have been lost over time. She may also encounter a young, talented artist or inventor who was never mentioned in the history books. This person could be creating something that will have a big impact in the future. And there's always the possibility that she meets a kind - hearted stranger who becomes her best friend in the past and has a lasting impact on her life, even when she returns to her own time.
The main characters are obviously Sakura and Sasuke. Sakura, with her strong will and medical ninjutsu skills, and Sasuke, known for his powerful Sharingan and his quest for power and revenge in the original Naruto story.
When it comes to Sakura's secret past in fanfiction, it can range from her early days in school before she became well - known in her field. Maybe she had a secret admirer that she didn't know about, or she was part of a small group that was working on a special project. Fanfiction allows for these unique and often unthought - of scenarios to be explored.
In this type of fanfiction, a great plot could be that Sakura and Sasuke are on a journey to find a cure for a strange illness that is affecting the ninja world. Along the way, they face many challenges. They might have to deal with enemy ninjas who want to stop them because they fear the power the cure could bring. Their relationship also evolves during this journey, as they rely on each other more and more, and Sakura's strength and Sasuke's cold exterior start to change as they get closer to their goal.
He might accidentally change the future. For example, he could prevent important events from occurring that were crucial for the development of the present he came from. Maybe he meets his parents at a younger age and reveals too much about the future, which could cause them to make different decisions.
In such a fanfiction, Naruto might try to prevent some of the tragedies that occurred in the past. For example, he could stop the Uchiha massacre. He would use his knowledge from the future to change things. Maybe he'd also be able to save some characters who died early in the original story, like Jiraiya. And he could potentially have a huge impact on the relationships between different clans, as he'd know about future conflicts.
One great fanfiction could be where Bella travels back and she and Jasper form an unexpected alliance against the Volturi. They use their combined knowledge of the future and Jasper's combat skills to change the fate of the Cullen family.
Another possible main character could be a historian or a scholar within the order. Their knowledge of the past could be crucial in helping the order navigate the historical period they travel to, and they might also be on a personal quest to discover something that has been lost in time.
