One interesting plot point could be how Naruto's relationships with his friends change. With the Rinnegan, he might seem more distant or different to them at first. But as he grows and learns to control it, they could come to rely on his new powers. Another point is how the ninja villages react to Naruto having the Rinnegan. Some might fear him, while others might try to recruit him. And of course, there's the mystery of how he got the Rinnegan in the first place.
In this fanfic, the way Naruto uses the Rinnegan to understand the history of the ninja world could be a great plot point. He might discover secrets that were long forgotten. Also, the conflict between Naruto's desire to use the Rinnegan for good and those who want to use it for evil would add depth. And Jiraiya's attempts to keep Naruto's Rinnegan a secret from certain dangerous forces in the ninja world while still allowing him to grow and develop his powers would be a very engaging part of the story.
