One possible plot could be Naruto discovering his connection to Tobirama. Maybe he uncovers some long - hidden jutsu or knowledge that was passed down from Tobirama within his family. This newfound heritage could give him an edge in battles against new and powerful enemies. For example, he might learn some unique water - style jutsu that Tobirama was famous for and combine it with his own Rasengan techniques to create a whole new attack.
Another idea for the plot could be centered around a mysterious enemy who is also related to Tobirama's past. This enemy targets Naruto because of his connection to Tobirama. Naruto has to dig deep into Tobirama's history to find a way to defeat this enemy. Along the way, he discovers secrets about Tobirama that were never known before, not only about his jutsu but also about his relationships and the true nature of his contributions to the village.
The plot could involve Naruto exploring the political implications of being a descendant of Tobirama. Tobirama was one of the founders of Konoha's political system. Naruto, with his new - found heritage, could try to reform or improve the existing system. He might face opposition from the traditionalists in the village who are resistant to change, but with his determination and the support of his friends, he could strive to make Konoha a better place.
