Well, perhaps Naruto isn't alone in his search for Sasori's scrolls. He could be joined by his friends like Sakura and Shikamaru. Sakura's medical knowledge might come in handy if there are any poisoned traps, while Shikamaru could strategize the best way to navigate through the area where the scrolls are located. Together, they face various challenges and enemies who also want the scrolls.
One possible plot development could be that Naruto discovers the scrolls in an old, abandoned hideout. Maybe the hideout is full of traps set by Sasori long ago. Naruto, with his ninja skills, has to overcome these traps to reach the scrolls.
The Akatsuki members could be the antagonists. Since Sasori was part of the Akatsuki, other members might want the scrolls for their own evil plans. They could try to stop Naruto from getting to the scrolls.
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.
One possible plot development could be that they initially fight against each other as enemies, not knowing their relation. Then, through some kind of accident or revelation, they find out they are brothers. This could lead to a lot of internal conflict for both of them, especially for Deidara who has been on the 'wrong side' in the eyes of Konoha. Another development could be that there is a third party who knows about their relation and tries to use it for their own gain, forcing Naruto and Deidara to work together to overcome this threat.
One possible plot could be that Naruto, for some reason, decides to adopt Sasori's more calculating and detached approach to combat. He might start using puppets or puppet - like techniques in battles, much like Sasori did. Maybe he's on a mission where he has to infiltrate an enemy base and he thinks acting like Sasori would be the best way to succeed.
If Naruto were Samui's brother in fanfiction, it would likely lead to some interesting character interactions. For instance, Naruto might have a closer bond with the Cloud ninjas. He could also get involved in resolving internal issues within the Cloud Village. Maybe he would be more welcomed in the Cloud Village than in the original story. Additionally, it could affect his relationship with Sasuke, as he might have a new support system in the form of Samui and her comrades.
One possible plot development could be Naruto using his new jutsu to break Yugito free from an enemy's trap. Another could be that Naruto's words break Yugito's negative mindset.
There could be a plot where they discover a new threat to the villages while living together. They then use their combined skills and knowledge to investigate. Gaara's knowledge of the desert and its secrets could be combined with Naruto's intuition and quick - thinking. They might also find some ancient power or technique during their investigation that could change the balance of power in the ninja world. This would lead to them having to decide how to handle this new power, whether to keep it secret or share it with the other villages for the greater good.
A possible plot development could be that Naruto's connection to the Nine - Tailed Fox gives him an advantage in a situation where Shirou was at a disadvantage. For example, if there was a powerful dark force in the story, Naruto could use the Nine - Tailed Fox's power to fight it off, while Shirou might have struggled more. Also, Naruto's charisma could attract different allies compared to Shirou, and these new allies could bring in their own sub - plots and story arcs.
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.
One possible plot development could be Naruto learning to master Samehada's unique abilities. Since Samehada can absorb chakra, Naruto might figure out a way to use this to his advantage in battles, like redirecting the absorbed chakra against his enemies.
