One possible scenario in this fanfiction could be that Naruto grows up with a more balanced upbringing. Tsunade might teach him medical ninjutsu and how to control his emotions better. Jiraiya, on the other hand, would surely train him in powerful combat techniques and in the ways of the sage. Naruto would probably be more mature and well - rounded at an earlier age, with a combination of Tsunade's tough love and Jiraiya's adventurous spirit guiding him.
A possible plot could be that Naruto, under the care of Tsunade and Jiraiya, discovers new aspects of his heritage. Tsunade might know some secrets about the Uzumaki clan that she shares with Naruto. Jiraiya, being his godfather - like figure, helps him explore these new revelations. Meanwhile, the Akatsuki could still be a threat, and Naruto, with his new skills and knowledge, has to fight against them to protect the village and his loved ones.
He would probably be an even more powerful ninja. Jiraiya could teach him amazing jutsu and Tsunade could train him in physical combat and medical ninjutsu. He'd likely have a more well - rounded skill set.
His training would be more comprehensive. Jiraiya could teach him Sage Mode earlier and more effectively. Tsunade could focus on his chakra control for medical ninjutsu.
In this fanfiction, their relationship would be transformed. They would be like a married couple in a way, but without the formalities. Jiraiya would probably tone down his womanizing ways as he has a family to think about now. Tsunade would be more open and less prickly around Jiraiya. They would bicker less and cooperate more. Their relationship would be centered around Naruto, and as he grows, they would grow together as a family unit, with their bond getting stronger over time.
In the official Naruto story, Naruto is the son of Minato and Kushina. However, in the realm of fanfiction, it's possible for such a concept to exist. Fanfiction writers often come up with creative and alternative storylines. But this goes against the original Naruto lore. It would be a very different take on the Naruto universe, with implications for Naruto's character development, his relationships with other characters like Sasuke and Sakura, and the overall plot. For example, his training might be influenced by Tsunade and Jiraiya in a more family - oriented way rather than just as mentors.
One possible plot twist could be that Naruto develops a different fighting style. Since Tsunade is strong in physical combat and medical ninjutsu, and Jiraiya is a master of various ninjutsu and toad summons, Naruto might combine their teachings in unique ways. For example, he could use medical ninjutsu to enhance his own physical abilities during combat, similar to how Tsunade uses her strength. Another plot twist could be in his relationships. With Tsunade and Jiraiya as his guardians, he might have a different attitude towards the Hidden Leaf Village's elders. He could be more critical or more understanding depending on how they've influenced him. Also, his training might be more focused on stealth and intelligence gathering, skills that Jiraiya was good at, rather than just brute strength.
He would probably also feel angry. After all, he has sacrificed so much for the village and for them. He might start to question his own beliefs and values. But Naruto being Naruto, he would not give up easily. He would try to prove his innocence and show them that they are wrong. He could go on a journey to find evidence or seek help from other allies who still believe in him, like Shikamaru or Kakashi.
He could also try to talk to them directly, despite the betrayal. Naruto has always believed in the power of communication and the bonds between people. He'd want to understand why they thought he was worthy of betrayal and try to convince them that they were wrong.
Well, it might have Naruto learning all sorts of cool jutsu directly from Jiraiya from a very young age. Maybe he'd grow up to be even more powerful and confident earlier in life. He could also inherit Jiraiya's carefree yet determined attitude more deeply.
