One possible plot could be that Naruto, as a male shinobi in a female - dominated world, has to constantly prove himself. He might face discrimination at first but through his unique skills and unwavering determination, he gradually earns the respect of the female shinobi. For example, his shadow clone jutsu could be something that the female shinobi initially underestimate but later come to admire. He could also form unique relationships with female characters, like a friendship with Sakura that takes on a new dynamic in this female - centric world.
The female characters would likely be more dominant. For example, Tsunade might have an even more powerful and overarching role in the shinobi world. She could be the one making most of the major decisions. The male characters, like Naruto, would have to adjust their behavior. Naruto might be more cautious in his actions as he is in a world where he is the minority. He would need to be more diplomatic in dealing with the female shinobi who hold most of the power.
One idea could be exploring the backstories of minor characters during the war. For example, how the war affected the normal villagers who were not shinobi. Another could be a story where a new, unexpected alliance forms between different ninja clans to fight a common, greater threat that was overlooked during the original war.
I think Obito could be really interesting. His complex backstory and his role in the war were so crucial. You could explore his internal struggle further, like his lingering feelings for Rin and how that influenced his actions during the war in more depth.
The Uchiha clan could be considered the best. They have powerful Sharingan abilities that give them an edge in combat, with the ability to copy techniques and predict movements. Their members are often highly skilled and have great potential.
In fanfiction, Naruto might fear a shinobi for various reasons. One could be that the shinobi has a unique and powerful jutsu that Naruto has never encountered before. For example, a shinobi with the ability to manipulate time could be extremely intimidating to Naruto as it goes against his understanding of combat and the ninja world. This new and unknown power could make him feel vulnerable.
You need to have a clear plot idea first. Then, build interesting characters and their development arcs. Also, create conflicts and resolutions to keep the story engaging.
You might be able to change the name by accessing the settings or profile section within the shinobi story game or platform. Look for options like 'Edit Profile' or 'Change Name'.
