Another aspect could be how Naruto's relationships change. His friends in the ninja world might be both intrigued and a bit wary of his magic abilities. Naruto could use magic to help his village in new ways, like using magic to enhance the village's defenses or to grow more crops. This would change the dynamic between him and the villagers as they see him in a new light.
One possible plot development could be Naruto using his newfound magic in combat. He might combine his ninja skills with magic spells, creating unique and powerful attacks. For example, he could use shadow clones and then have each clone cast a different magic spell, overwhelming his enemies.
One possible plot development could be Hanabi trying to get closer to Naruto. She might start by finding excuses to be in the same place as him, like showing up at his favorite training spots. Another could be her trying to impress Naruto with her skills, perhaps by showing off her new jutsu in front of him. And she could also start to compete with Hinata in a friendly way for Naruto's attention.
In the 'naruto has no eyes fanfiction', the plot might involve Naruto discovering a new form of chakra that is unique to his condition. This new chakra could give him abilities that he didn't have before, like the ability to sense the emotions of his opponents. There could also be a plot twist where Naruto's blindness is actually a part of a greater prophecy, and he has to fulfill it in a way that no one expected.
It could also be that the sister, in an attempt to help Naruto, gets involved with some dangerous characters or situations. Maybe she tries to find someone powerful to plead Naruto's case, but that person has some ulterior motives. This would add a lot of twists and turns to the story, as Naruto then has to not only deal with his own problems but also save his sister from the trouble she has gotten into while trying to help him.
One possible plot development could be Naruto using the flowing eye to discover new jutsu. For example, he might be able to see the chakra flow in a different way and create unique attacks. Another could be that the flowing eye attracts the attention of new enemies who want to either steal it or destroy it because they fear its power.
Well, in such a fanfiction, Naruto might start to experiment with new and extremely powerful jutsus that were previously impossible due to chakra limitations. He could also use his infinite chakra to help rebuild and improve the Hidden Leaf Village at a much faster rate. For example, he could power large - scale construction projects or provide continuous chakra for defense mechanisms. This would change the balance of power not only in the Leaf but also among the other hidden villages.
Perhaps Naruto discovers some hidden powers or abilities that Kunou has inherited from him, which leads to a whole new adventure. They might go on a journey to understand and control these powers together. Also, Naruto could face challenges from the village elders who are not so accepting of Kunou at first.
Another plot development could be that with Sarutobi as his adoptive father, Naruto has access to different mentors. Sarutobi could call in favors from other great ninjas to train Naruto. This would expose Naruto to a wider variety of fighting styles and strategies. Maybe he gets trained by Kakashi earlier, or even has the chance to learn from some of the retired or older ninjas who usually keep to themselves.
Well, one possible plot development could be that Naruto's hatred for Sakura creates a lot of tension in the story. Maybe it leads to some kind of rivalry where they constantly compete in missions or training. And Sakura's love could be unrequited at first, causing her to strive harder to prove herself to Naruto. Another development could be that the fanfiction explores the reasons behind Naruto's hatred, like some past misunderstandings that need to be resolved for them to have a normal relationship.
Well, it could be a moment of deepening their emotional connection. Maybe they start off shyly, but as they share the bath, they open up about their fears and hopes. For example, Adam could talk about his insecurities regarding his past as the Beast, and Belle could comfort him, leading to a stronger bond between them.
One possibility is that Naruto's friends launch a rescue mission. They would use their unique skills, like Sasuke's Sharingan or Sakura's medical ninjutsu combined with her combat skills, to find and save Naruto.
