Well, Naruto is known for his strong will and great power. In fanfiction, someone might ask Naruto for help because he has proven himself to be a reliable hero. He has saved the village multiple times, so people trust him to handle various problems, whether it's dealing with a new threat or helping with personal issues.
Maybe he has some personal grudges against the village. For example, he might have felt betrayed by the village in the past and that made him reluctant to offer help.
One popular theme is the daily life in Konoha. It could be about the characters going about their normal days, training, having fun at the local shops, or just hanging out with friends. Another theme is about Konoha during a war or a major threat. How the village prepares, the strategies they come up with, and how the characters, especially Naruto, contribute to the defense. And then there's the theme of Konoha's past. Stories that explore the history of the village, the founders, and how things have changed over time.
In fanfiction, there could be a situation where a new and dangerous jutsu has been developed by an enemy. This jutsu is causing chaos in Konoha. Naruto, with his own unique set of jutsus and his ability to learn quickly, could be asked to analyze and counter this new threat. Also, if there are missing ninjas causing trouble outside the village and affecting Konoha's reputation, Naruto might be sent to bring them back or deal with them in some way. His reputation as a powerful and just shinobi makes him the go - to person for such tasks.
One possible reason could be feeling betrayed by the village leaders. Maybe they made decisions that Naruto strongly disagreed with, like how they treated certain groups or individuals. If Naruto felt that Konoha was no longer the place that stood for justice and fairness as he once believed, he might abandon it.
Well, it would be a big loss for Konoha. Naruto is a powerful ninja, and his absence would mean one less strong fighter to defend the village. Ino, too, has her unique skills in mind - related jutsu and communication. Their departure might also lower the morale of other ninja, especially those who were friends with them or looked up to them.
In some cases, it could be because the writer wants to deviate from the typical 'hero is loved' trope. They might think that exploring a scenario where Naruto is hated in his own village can bring out new aspects of his character. It could also be related to exploring the politics within the village. For example, perhaps there are factions in Konoha that see Naruto as a threat, either because of the Nine - Tails inside him or because they fear his growing power. This kind of fanfiction can dig deep into these political undercurrents.
In some fanfictions, Naruto might be depicted as hating Konoha due to feeling betrayed. For example, if the village turns against him unjustly or fails to support him when he needs it most. Maybe they suspect him of something he didn't do, like being involved in a crime against the village, which could lead to his hatred.
