There could be. Fanfic writers often explore very extreme and alternate storylines. But this kind of story would be a major deviation from the main Naruto narrative. Regarding the female Kyuubi aspect, it could add an interesting twist to the otherwise shocking plot of Naruto killing Konoha. Maybe in this fanfic, the female Kyuubi has some influence on Naruto that leads him to such a drastic action.
It's difficult to say for certain. While the Naruto fanfic community is large and diverse, a story where Naruto kills Konoha is not a common or mainstream idea. The addition of the female Kyuubi concept makes it even more specific. It might exist in some corner of the internet, perhaps written by a writer who wanted to explore a very different and edgy take on the Naruto universe, but I haven't come across it myself.
I'm not sure if there is such a specific fanfic. There are countless Naruto fanfics out there, but a plot where Naruto kills Konoha is quite a dark and unorthodox one. It might go against the general themes of the original series. However, the world of fanfiction is vast, and it's possible that someone has written such a story with a female Kyuubi element.
Well, one possible plot could be that Naruto is betrayed by Konoha in some extreme way. Maybe he discovers some dark secrets about the village leadership that involve using him as a tool all along. This betrayal could push him to the edge and make him turn against Konoha, leading to a situation where he kills those who he feels have wronged him.
One possible reason could be that the female Kyuubi has some sort of mind - control over Naruto. Maybe she has her own vendetta against Konoha and uses Naruto as a tool to carry out her revenge. Another reason might be that Konoha has done something extremely unforgivable in the eyes of Naruto, like harming the female Kyuubi in a cruel way that makes Naruto snap and turn against the village.
One possible fanfiction could be about Naruto forming a unique bond with the female Kyuubi. In this story, Konoha's actions towards Naruto in the past might be re - examined in a negative light. Maybe Naruto, with the help of the female Kyuubi, decides to make Konoha face its wrongdoings. This could lead to a series of events where Naruto challenges the old traditions and power structures in Konoha that have been unfair to him.
The ANBU black ops could also play the role of antagonists. They are the ones who carry out the village's more secretive and sometimes morally gray missions. If they are ordered to hunt Naruto down unjustly, they would be in Naruto's way and could be the reason for his violent reaction towards Konoha.
One potential consequence could be widespread destruction. The Kyuubi is an extremely powerful force. Buildings would likely be demolished, and many shinobi might be injured or killed trying to combat it. Another consequence could be a shift in the power dynamics within Konoha. Some might see Naruto as a threat, while others might try to use this situation to gain power themselves.
In the 'naruto banished kills the kyuubi fanfic', it might start with Naruto being wrongly accused and banished. As he's on his own, he starts to explore his relationship with the Kyuubi more deeply. He realizes that the only way to break free from the chains that the village's treatment has put on him is to defeat the Kyuubi. So, he uses his ninja skills, combined with some unexpected twists in his chakra control, to fight and kill the Kyuubi. This would completely change the Naruto universe as we know it, since the Kyuubi is such a fundamental part of the story.
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 immediate consequence would be the destruction of Konoha, which is a major power in the Naruto world. This would create a power vacuum that other villages might try to fill, leading to possible wars and political unrest.
Naruto's character would likely become more independent. Away from Konoha, he has to rely on himself and the female Kyuubi. He might become more cautious as he no longer has the safety net of his village. His view of friendship could also change. Since he's with the female Kyuubi, he might develop a deeper understanding of different beings and their motives.
The village would also start to question how such a thing could happen. There would be investigations into whether Naruto was acting alone or if there was some greater conspiracy at play. Some might even blame the Hokage for not being able to prevent this tragedy from occurring.
