He could feel a sense of guilt. Sasuke might think that his actions or their relationship issues pushed Naruto to leave. He may then set out to find Naruto, not only to bring him back but also to resolve their long - standing issues. For example, if there were unspoken words or unresolved fights between them, Sasuke would see this as an opportunity to set things right.
One possibility is that Naruto is on a quest for self - discovery. Leaving the village to find the Sage gives him a chance to be away from the familiar and face new challenges alone. He might encounter different types of enemies and allies during this journey. This could also be a way for him to prove himself not just to the village but also to himself. He wants to show that he can grow and become stronger without always relying on the village's resources.
Well, Naruto could leave the village in a fanfic due to a prophecy. He might believe that leaving is the only way to fulfill a greater destiny that the village can't support. As he leaves, he starts to explore different cultures of the ninja world. He learns about new forms of jutsu and how other villages operate. He could also form a team with outcasts from different villages, and together they strive to change the way the ninja world views things.
Obviously, Sakura herself is the main character. Naruto could also be in it. Maybe he tries to convince Sakura to stay or he could be the one to help her prepare for her journey. Sasuke might be another character. He could have some influence on Sakura's decision to leave, either by his own actions or just his presence in the village.
Perhaps Sakura leaves the village because she feels out of place. She might have had some falling - out with her friends or just doesn't feel like she belongs there anymore. So, she packs her bags and sets off on a solo adventure to find a place where she can truly be herself.
The Leaf Village would be in chaos at first. Hinata is an important member of the Hyuga clan, and her kidnapping would not be taken lightly. The Hokage would immediately call for an emergency meeting. They would start by sending out search teams, likely led by some of their best shinobi like Kakashi or Shikamaru, who are known for their intelligence and combat skills.
In the sasunaru context, perhaps a rift between Sasuke and Naruto makes Naruto feel like he needs to leave to sort out his feelings. He might think that staying in the village constantly reminded of Sasuke and their complicated relationship is too much to bear, so he leaves to find his own path and hopefully reconcile with Sasuke on his own terms.
" Blooming Flowers and Leaves " was a TV series that described the development of several poor villages under the jurisdiction of Fengxiang Town, which was located in the hinterland of the Dalou Mountain Range, from poverty to prosperity. With Huamao Village as the representative, the play depicted the story of the new era of the masses working together to help the poor. Although it was not mentioned that the play was about the poor village in the 1950s, from the plot introduction and related reports, it focused on the changes in poverty and ecological beauty in the countryside. Therefore, the play may not fit the 1950s background you mentioned.
Naruto might encounter a group of rogue ninjas. At first, they seem like enemies, but as he gets to know them, he realizes they have their own reasons for being outcasts. They could teach Naruto some unorthodox fighting styles that are not taught in the Leaf Village. Also, there could be a mysterious traveler who has knowledge about Naruto's family that even he doesn't know. This traveler could be the key to unlocking some hidden power within Naruto.
Definitely Naruto and Sasuke. Naruto is the one leaving the village, so he's a central figure. Sasuke, given the 'narusasu' aspect, is bound to play a crucial role too. He could be the one Naruto is leaving behind, or he could be the one who follows Naruto out of the village. There might also be other supporting characters from the Naruto universe like Kakashi or Sakura who could be affected by Naruto's departure.
