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.
One possible plot development could be Naruto being initially confused about having a maid. He might be a bit shy or not used to someone taking care of him in that way. The maid could also have a mysterious past that gets intertwined with Naruto's own journey. Maybe she has some hidden skills or knowledge that helps Naruto in his ninja training.
Perhaps the plot could involve Sarutobi protecting Naruto from the more malicious elements in the village. He could use his influence to ensure Naruto has a normal childhood, or as normal as it can be for a jinchuriki. Naruto might also inherit some of Sarutobi's wisdom and leadership skills, which would be important for his future development.
One possible plot development could be that Naruto gains new powers under Zeltrech's guidance. Zeltrech might teach Naruto unique magic or combat skills that are different from the ninja arts he's used to. For example, Naruto could learn to manipulate magical energy in ways that enhance his already formidable strength.
One possible plotline could be Naruto growing up with a different set of values and training methods. Instead of the rough start he had in the original story, he'd be mentored by the Sarutobi clan's elders. He might learn more about the history and secrets of Konoha at an earlier age, which could lead to him being more politically aware and better equipped to handle future threats. For example, he could be trained in unique Sarutobi jutsu from a young age, giving him an edge in combat.
The plot might involve Naruto being trained by both Kurenai and Asuma to become a more well - rounded ninja. Kurenai could focus on his stealth and genjutsu skills. Naruto, who has mainly focused on his ninjutsu and taijutsu, would benefit greatly from this. As for the relationship with the village, with Kurenai and Asuma as his adoptive parents, Naruto might gain more respect from some of the villagers who previously looked down on him. This could also lead to changes in how he interacts with his peers, like Sakura and Sasuke.
It could be that Naruto has a different view of leadership than Sarutobi. Naruto might see Sarutobi's leadership as being too passive or too focused on maintaining the status quo. He, with his more energetic and revolutionary ideas, may resent Sarutobi for not being more progressive in making the village a better place for everyone, including himself.
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.
One possible plot development could be that Harry discovers new magical abilities or knowledge within the Greengrass family. Maybe they have a unique magical heritage that helps him in his fight against Voldemort.
Well, in this fanfic, Naruto could start to heal from his past neglect. Tsunade might introduce him to different aspects of the ninja world that he was previously unaware of. For example, she could take him on diplomatic missions to other villages, which would expand his understanding of international relations among ninja clans. In terms of his growth as a ninja, Tsunade could also help him master some of the more advanced medical ninjutsu. This would not only make him a more versatile shinobi but also give him a new skill set to rely on in combat. And of course, their relationship could also face challenges, like when Tsunade has to make difficult decisions regarding the village that might put Naruto in a tough position.
One possible plot development could be Malfoy struggling to fit into Hermione's world. He might be resistant to her friends and the values they uphold. Another could be Hermione trying to get Malfoy to accept his new family situation. Maybe there would be a plotline where Malfoy's old pure - blood family tries to interfere with the adoption.
