What could be the reasons for Sakura leaving the village at age 13 in fanfiction?

Perhaps in the fanfiction, Sakura had some unique ability that was not accepted or was feared in the village at such a young age. This led to her family deciding to leave the village so that she could grow up without being ostracized or in danger because of this ability.

A simple reason could be for adventure. Sakura might be tired of the daily routine in the village and yearn for new experiences outside. So she decides to leave to explore the world and test her skills against new opponents.

For her friends, it could be a shock. They might feel betrayed, especially if she left without much explanation. Her best friend might feel sad and lonely, constantly wondering why she left and if she would ever come back.

They might leave to seek new forms of power or knowledge. There could be things outside of Konoha that they believe will help them become better at their ninja skills. For instance, they might have heard of a special dojo or a hidden scroll in another land that could enhance their abilities.

In some fanfictions, Naruto might leave because of a rift within the village. If there are political factions that oppose him or his methods, and he feels that he can no longer operate effectively within the village, he may choose to leave. This could also be due to a misunderstanding or false accusations against him that he can't seem to clear up while remaining in the village.

One reason could be a sense of disillusionment with the village's leadership. Maybe they discover some dark secrets about the elders and decide they can't be part of it anymore. Another reason might be to protect the village in their own way. They could think that by leaving, they draw danger away from their home. Also, they might be seeking a greater power or knowledge that can only be found outside the village.

One reason could be that Naruto discovers some dark secrets about the village that make him lose faith in it. Maybe something related to the 'dark sage' in the story reveals a side of the village's history or leadership that he can't accept. Another reason might be that he's framed for a crime he didn't commit, and instead of waiting for the village to believe in his innocence, he decides to leave. It could also be that he feels restricted by the village's rules and wants to explore a different way of being a ninja, which the dark sage figure represents in some way.

In the fanfic, they could leave the village in search of a long - lost ninja art. They believe this art could be the key to bringing peace to the ninja world. During their travels, they encounter various enemies who also seek the art. Sasuke and Sakura must use their skills and teamwork to overcome these foes and continue their quest.

They could be leaving in search of new training opportunities. Konoha might not offer the advanced or specialized training they seek. So, they decide to leave to find a place where they can grow stronger and expand their abilities.

Perhaps she left for what she thought were the right reasons at the time, like following her own path or someone else's influence. But then, she discovers that life without Naruto is lacking. She misses his unwavering support, his positive energy, and his ability to always see the best in her, which leads to her regret.
