In this fanfiction, the plot could revolve around Naruto and the Jinchuuriki family being hunted by a powerful organization. They are forced to go on the run and hide in different parts of the ninja world. During this time, Naruto discovers more about their shared heritage as Jinchuuriki. They also have to deal with the internal struggles of some Jinchuuriki who are not fully accepting of their role, and Naruto has to use his leadership skills to keep them together and safe.
Well, the story might revolve around the brother's different upbringings. Naruto grew up in Konoha, but his brother could have been raised elsewhere. This difference in environment could lead to different views on being a jinchuuriki. For example, Naruto might see it as a way to protect the village, while his brother could see it as a curse at first. As the story progresses, they could learn from each other's perspectives and grow stronger together.
Perhaps the story shows Naruto exploring different aspects of the ninja world that are not related to jinchuuriki. He could be delving into ancient ninja techniques or solving mysteries that have nothing to do with the tailed beasts inside him. It might also highlight his relationships with other characters in a new light, like his rivalry with Sasuke in a non - jinchuuriki - related context.
It could be Orochimaru. He has always been interested in power and the secrets of the tailed beasts. So, he might see Naruto and the Jinchuuriki family as a source of great power to experiment on or steal from.
One possible plot twist could be that Naruto and Hinata have to quickly learn to control their newfound Jinchuuriki powers. Maybe they are suddenly thrust into a situation where an ancient evil is awakened and only their combined Jinchuuriki abilities can stop it. For example, they might discover that there is a hidden prophecy about two Jinchuuriki working together to save the world.
Well, you could focus on the relationship between the jinchuuriki and their extended family members in the fanfiction. For instance, how does the jinchuuriki's relationship with their grandparents change when they find out about the tailed beast? Also, a plot could revolve around the family trying to help the jinchuuriki control the power of the tailed beast. They could seek out ancient scrolls or wise sages to learn techniques that would make it easier for the jinchuuriki to co - exist with the beast.
One possible plot could be that an ancient and powerful tailed beast is released. Naruto and Hinata, in their quest to protect the village, end up being the only ones able to bond with it. They then have to learn to control the new power within them while facing opposition from other villages who fear their combined strength.
One possible plot twist could be that Naruto discovers a new power source that makes being a Jinchuuriki seem obsolete. Maybe he finds an ancient artifact or a new form of chakra that is more powerful and doesn't have the drawbacks of being a Jinchuuriki. Another could be that he has a moral dilemma about the nature of the Jinchuuriki system and decides to quit in protest. For example, if he realizes that the Jinchuuriki are being used as tools more than protectors.
One possibility could be that Naruto focuses more on mastering unique ninja techniques that are not related to the power of the tailed beasts. For example, he might delve deeper into his wind - style jutsu and create new and powerful variations.
A plot twist might involve the other villages' reactions. When they find out Naruto is the jinchuuriki of two bijuu, they could either see him as a greater threat or try to ally with Konoha. Maybe some villages would send spies or assassins to either capture Naruto or steal the power of the bijuu from him. This would create a lot of political intrigue and danger for Naruto and his friends.
I'm not sure specifically as there could be many different plots in such a fanfiction. Generally, it might involve the Naruto character who is a Jinchuuriki (a host of a tailed beast) having some sort of connection or interaction with the Shinigami (the god of death in some contexts). It could be about how his Jinchuuriki powers are affected by this connection, or perhaps adventures that come from it.
