I'm not sure specifically as it depends on the author's creation. But it might involve Naruto having some sort of conflict with Kumo and then abandoning it. Maybe there are issues like political differences, or problems with the shinobi from Kumo that lead Naruto to this decision.
In this fanfiction, Naruto is the central figure. Alongside him, we might expect to see characters like the Raikage from Kumo. Their interactions and differences in ideologies could be a major part of the story. There could also be some minor characters from both Konoha and Kumo who help to build the background and context of Naruto's decision to abandon Kumo, like the shopkeepers or other common shinobi who witness the events leading up to this big decision.
Maybe in the fanfiction, Naruto neglected Kumo because he was too focused on his own village's problems. But then something major happens in Kumo, like a powerful enemy targets them. Naruto realizes his mistake and goes to Kumo to make amends. He teams up with the Kumo shinobi, and they work together to fend off the threat. Along the way, he learns about Kumo's unique culture and forms strong bonds with their ninja.
Perhaps Naruto is in Kumo to search for a missing Konoha ninja. While there, he uncovers a conspiracy within Kumo that threatens both villages. He then has to team up with some of the Kumo ninjas who initially distrusted him to stop the threat.
Well, one possibility could be that Naruto has to adapt to the different culture in Kumo. He might face challenges in making new friends as the people there have different values and ways of life compared to Konoha. He could also discover new jutsus unique to Kumo and incorporate them into his own fighting style.
If Naruto joins Kumo in fanfiction, it might start with Naruto being sent on a mission to Kumo as an ambassador of sorts. Once there, he becomes intrigued by their combat techniques and decides to stay for a while to train. He could get involved in Kumo's internal power struggles. For example, there might be a faction in Kumo that doesn't trust him and tries to drive him out, while another faction sees his potential and wants to keep him. His presence could also change the dynamics between Kumo and other ninja villages as they see Naruto's new allegiance.
One possible plot could be that Naruto goes to Kumo but is not well - received there. Maybe the people of Kumo are still suspicious of him because of his status as a Jinchuuriki. They could isolate him, and Naruto has to struggle to prove himself worthy of their trust. He might also face discrimination from some of the Kumo ninja.
It could be that Kumo has a rogue group within their village that wants to use Naruto for their own malicious purposes. They kidnap him in the chaos of a diplomatic visit or something similar. Once kidnapped, Naruto finds himself in a difficult situation as he is far from home. But he uses his never - give - up attitude and starts making friends with some sympathetic Kumo ninjas who help him in his fight against the rogues and eventually his escape back to Konoha.
Well, one possible plot could be that Fem Naruto goes to Kumo to seek new challenges and training opportunities. In Kumo, she might face discrimination at first because she's from Konoha. But as she shows her strength and unique skills, she gradually earns the respect of the Kumo ninjas. Maybe she forms an unlikely friendship with some of the Kumo shinobi and together they take on powerful enemies that threaten both Kumo and Konoha.
One possible plot could be that Naruto is on a mission near Wave and discovers a threat from Kumo ninjas. He decides to save Wave by using his unique skills and his knowledge of Kumo's fighting styles. Maybe he forms an alliance with some of the local Wave defenders and together they outwit the Kumo forces.
One common plot element could be Naruto having to adapt to the different culture in Kumo. For example, the way they train or their social norms might be different from Konoha.
