The plot might involve Naruto getting Shisui's eyes in a strange accident. With these eyes, he discovers a hidden conspiracy within the Hidden Leaf Village. There are some rogue ninjas who are planning to use a powerful jutsu that can only be countered with the unique abilities of Shisui's eyes. Naruto, with his new - found powers, has to team up with his friends like Sasuke and Sakura to expose the conspiracy and save the village. Along the way, he struggles with controlling the Sharingan's powers and the emotions that come with it.
Perhaps the fanfic could focus on a training arc. A young ninja, who is a big fan of Shisui, discovers a way to inherit or mimic the abilities of Shisui's eyes through some special training method. This training would be filled with difficulties and self - discovery. As they progress, they start to understand the true burden that comes with such power. They might also attract the attention of some of the village's elders or enemies, which would lead to various conflicts and adventures.
It could make Kakashi more protective of Naruto. Since Kakashi is well - aware of the power of Shisui's eyes, he would know the potential danger Naruto is in. He might train Naruto more intensively to help him control the eyes and also protect him from those who would seek to take the eyes for themselves.
One possible plot could be that Naruto gains Shisui's eyes through some mysterious ninja art. With these eyes, he could have enhanced perception abilities, like being able to see through genjutsu more easily. This would change his fighting style and make him even more formidable against opponents. He might also use the unique powers of Shisui's eyes to uncover hidden secrets in the ninja world, leading to new adventures and alliances.
Well, having Shisui's eyes would likely give Naruto enhanced genjutsu abilities. Shisui's eyes are known for their powerful genjutsu. Naruto could use this to deceive his opponents more effectively in battle. He might be able to cast illusions that are much more difficult to break, and it could also potentially give him an edge in stealth operations as he could use the genjutsu to misdirect enemies.
Well, if Naruto has Shisui's eyes, he would likely gain the power of the Sharingan. The Sharingan can copy jutsus just by seeing them once. So Naruto could potentially learn a whole lot more jutsus much faster. And with Mikoto involved in the fanfiction, perhaps there's some connection to the Uchiha clan that gives Naruto a deeper understanding of their ways and powers. This could make him even more formidable in battles, as he combines his own Uzumaki chakra and tenacity with the powers associated with the Uchiha.
One possible plot development could be that Naruto becomes a target. Since Shisui's eyes are so powerful, other villages or rogue ninja might want to take them from Naruto. This would lead to a lot of battles and Naruto having to constantly defend himself. Another development could be that Naruto tries to master the abilities of the Sharingan quickly. He might seek out people who know about the Sharingan, like Kakashi or Sasuke, to train with.
The mystery surrounding the eyes is also appealing. In the Naruto universe, there are always secrets. With Shisui's eyes, there could be secrets about their origin or even some hidden powers that were not fully explored in the original series. A fanfic could dig into these mysteries. Also, the psychological impact on the character who has the eyes is important. These eyes are a great power, and with great power comes great responsibility. How does the character deal with the pressure? Do they become paranoid or do they rise to the occasion? This can be a great area to explore in the fanfic.
Redemption is often seen. Maybe a character who was once on the wrong path gets Shisui's eyes and sees it as a chance to make up for their past mistakes. They use the power of the eyes to protect those they once hurt or to fight against the forces of evil that they were once a part of.
Well, Naruto already has his own powerful abilities like the Nine - Tails chakra. But with Shisui's eyes, he'd likely gain the power of the Sharingan. He could probably use the Sharingan's basic abilities such as seeing the flow of chakra and predicting movements better. Maybe he could also use Shisui's special jutsu, like Kotoamatsukami, which could be a game - changer in battles and in influencing others without them even realizing it.
