In this kind of fanfiction, one possible plot could be that Naruto discovers a hidden ancient jutsu. With great determination and after many trials, he manages to use this jutsu to break the seal that binds Kurama. Then, Kurama, instead of being hostile as expected, actually thanks Naruto for freeing it. They form an even deeper bond and decide to work together to protect the Hidden Leaf Village from a new and powerful enemy that is approaching.
Well, in some fanfics, the story might start with Naruto getting a premonition or some kind of sign that Kurama is suffering under the seal. So, he decides to free Kurama. He then embarks on a journey to find a way to break the seal. Along the way, he meets various characters from the Naruto universe who either help or hinder his progress. Once he finally frees Kurama, they team up to face a greater threat to the ninja world that neither could have faced alone.
The antagonists could be a secret organization within the Hidden Leaf Village itself. They are afraid that if Kurama is freed, it will bring destruction to the village. They think Naruto is being reckless and they will do anything to stop him, including framing him for crimes he didn't commit and turning his friends against him, all in an effort to keep Kurama sealed.
The plot of a 'naruto frees kyuubi fanfiction' might involve an external threat to the village. This threat is so great that Naruto realizes he needs the full power of the Kyuubi, not just the limited access he has through the seal. So, he starts to work on breaking the seal. Along the way, he has to face opposition from some in the village who fear the unleashed Kyuubi. But Naruto is determined. He finally frees the Kyuubi and together they defeat the external threat. After that, the Kyuubi decides to stay with Naruto as a friend and ally, seeing the true nature of the young ninja.
One possible plot could be that Naruto, with his strong sense of justice and determination, discovers Jenova being held captive in some strange, other - worldly prison. Using his ninja skills like shadow clones and rasengan, he battles the guards or forces holding Jenova. He then frees her, not fully understanding the implications. Jenova, being a complex and powerful entity, initially sees Naruto as a tool but eventually starts to respect his unwavering will.
The main characters are Naruto and Kurama, of course. Naruto is the protagonist who wants to free Kurama. Kurama is the nine - tailed fox that is sealed within Naruto and is the one being freed.
One possible plot could be that Kurama, through some strange magical or dimensional rift, gets a glimpse into the world where Slade exists.

Well, it could be about Kurama having some sort of connection or interaction with Slad. Maybe Slad is a new character who has the ability to communicate with Kurama in a different way than Naruto.

Well, it could be about a high - tech world where Naruto has a mecha version of Kurama.
