Well, after that event, the story could branch out in many ways. Maybe some of the more radical shinobi in Konoha would try to eliminate Naruto immediately. But his closer friends would form a sort of resistance to protect him. As Naruto tries to subdue the Kyuubi, he might also discover new powers or abilities within himself. This could lead to a new power - up for him in the long run. At the same time, the village would need to start the process of rebuilding, which could bring in new characters or storylines related to construction, resource management, and the like.
After Naruto releases Kyuubi on Konoha, the story could take a turn towards a redemption arc for Naruto. He would have to face the consequences of his actions and work hard to earn back the trust of the villagers. Meanwhile, other characters could start to explore the reasons why Naruto did what he did, which might uncover some hidden secrets about Naruto or the village itself.
The development varies a great deal. In some fanfictions, after releasing the Kyuubi on Konoha, Naruto is exiled. He then has to find his own path outside the village. Along the way, he meets new allies who help him understand his power better. He might also encounter new enemies who are interested in the Kyuubi's power. Eventually, he could return to Konoha as a more powerful and wiser shinobi to make amends.
When Naruto releases the Kyuubi in the fanfic, it might change his relationship with his sensei, Kakashi. Kakashi would be on high alert, ready to step in if Naruto loses control. At the same time, he would be guiding Naruto on how to better manage the Kyuubi's power. This could bring them closer as Naruto learns from Kakashi's experience. And Naruto's relationship with the other ninja in the village would also shift. Some would look up to him more as a powerful force to protect them, while others might be jealous of his new - found strength.
In some fanfictions, the immediate consequence could be destruction. Buildings might be razed and many shinobi could be injured or killed. The village would be in chaos as they try to either contain Naruto or the Kyuubi's power. There could also be a shift in the power dynamics, with some seeing Naruto as a threat and others trying to find a way to calm him down and reseal the Kyuubi.
Naruto himself might start to form his own group or alliance outside of Konoha. He could gather other outcasts or those who have a grudge against the major ninja villages. This new group could then have its own goals, like trying to reform the ninja world in a way that is different from how Konoha and the other villages operate. As the story progresses, there would be inevitable clashes between Naruto's new group and Konoha.
In some fanfictions, after the Kyuubi is extracted, Naruto's relationships play a big role in the story development. His relationship with Sakura could change, for example. She might see him in a new light and become more protective. And with Kakashi, Kakashi could take on a more father - like role in helping Naruto recover. Also, the story could develop into a plot where Naruto discovers a new power within himself that was hidden because of the Kyuubi's dominance all this time.
Well, their friendship develops through Naruto's determination. He doesn't see the Kyuubi as just a source of power. Instead, he tries to understand it. Naruto's positive attitude gradually breaks down the Kyuubi's initial hostility. As time goes by, they start to communicate more, and Naruto shows the Kyuubi that he respects it as an individual. This mutual understanding forms the basis of their friendship.
As the story progresses in a 'Naruto Defects from Konoha Fanfic', Naruto might also start to question his own identity and values. He has grown up believing in Konoha's ideals, but now that he's outside the village, he has to re - evaluate everything. He could meet new people from different villages or backgrounds who challenge his previous beliefs. This internal struggle, along with the external conflict with Konoha, can make for a very engaging and multi - faceted story. His actions might also have a significant impact on the relationships between different villages in the ninja world, as his defection is a major event that shakes the status quo.
At first, it might be a relationship of mutual suspicion. Naruto is used to seeing Kyuubi as a source of power but also a potential threat. As the story progresses, they start to understand each other more. For example, through shared experiences in battles.
Often, his friends in Konoha will start to search for him. They might split into teams and scour the surrounding areas. For example, Sasuke could use his Sharingan to look for any signs of Naruto's departure. Meanwhile, back in Konoha, there could be unrest as the villagers start to worry about the safety of the village without Naruto.
They might encounter new allies. These could be people with different abilities and backgrounds. For example, they could meet a group of rogue ninjas who turn out to be good-hearted and help them on their journey.
