Maybe it's a way to protect the village. The ravens could act as an early warning system. They can fly over Konoha and the surrounding areas, and if they detect any incoming threats, they can quickly report back to Naruto. It's a form of aerial defense that can complement the existing ninja guards.
He could start by using his chakra to communicate with them. Naruto has a large amount of chakra, and he might be able to establish a mental link with the ravens. Through this link, he can give them commands and instructions.
One possible plot twist could be that Naruto discovers a hidden power within Darth Raven's army that he can use to his advantage. Maybe it's a special type of chakra or a unique weapon. Another could be that members of the army start to rebel against Naruto, believing he is leading them astray. This would create internal conflict.
He might use his charisma. Naruto is known for being able to inspire people. He could convince soldiers who were once loyal to Darth Raven to follow him instead. He may also introduce new training methods or strategies that make the army more effective, thus attracting more recruits.
Well, he might start by using his charisma. Naruto has always been good at making friends. He could reach out to old allies from his village, like Shikamaru and Choji. Also, he might convince some of the outcast ninja who have been mistreated in other villages to join him. His reputation as a hero who saved the world would surely attract a lot of people.
It could be a symbolic way of showing the destruction of hope. In the Naruto series, Naruto represents hope. By having Hinata kill him, the writer might be trying to convey a sense of hopelessness or the end of an era. This could be part of a larger, more complex story about the fall of the ninja world as we know it in the Naruto franchise.
There could be several reasons. One might be that they simply have a dislike for the Naruto franchise and are using this extreme concept as a form of protest in a very unorthodox way. Another possibility is that they are just exploring some really dark and unethical ideas for the sake of creativity, without considering the negative impact it could have on the fans of the series. It's also possible that they don't fully understand the significance and positive influence of the Naruto character and are just making a random and inappropriate statement through this fanfiction.
One challenge is trust. Not everyone will immediately believe in Naruto's intentions. Some may think he is trying to gain power for himself. Another challenge could be resources. Feeding, housing, and training an army requires a lot of resources. He needs to find ways to get enough funds and supplies.
One possible motivation could be to create drama. By having Naruto kill Sarutobi, it would shock the readers and create a huge rift in the story's world. It might also be a way to explore Naruto's dark side that we rarely see in the official story.
Maybe the writer just wants to be different. Since Naruto is usually seen as a hero, they might think it's edgy to write him as a loser.
Tsunade could play a crucial role. She could use her vast knowledge of resources and economics to secure the funds and materials needed for the fleet. Jiraiya, if he were still alive, would bring in his worldly knowledge and connections from his travels. He could help Naruto find rare and valuable materials from far - flung places for building a truly remarkable fleet.
