One interesting plot could be that Naruto awakens the Sharingan during a battle with a powerful new enemy. This unexpected turn gives him new abilities like predicting the enemy's moves better. Another plot might involve Naruto getting the Sharingan in a dream and then slowly learning to use it in the real world. It could also be that Naruto inherits the Sharingan from a long - lost relative, which changes the whole dynamic of his relationships in the ninja world.
After awakening the Sharingan, Naruto may become more perceptive. He starts to notice small details in his surroundings and in people's behavior that he missed before. This helps him in his ninja missions as he can plan better strategies. His confidence also grows as he realizes he has a new and powerful tool at his disposal.
Naruto would become more perceptive. The Sharingan gives the ability to see chakra flow and predict movements. So, he'd be better at combat, and his confidence would likely increase. He might start to rely more on his new visual powers rather than just his raw strength and Nine - Tails chakra.
Sakura could be an unexpected character to have the Sharingan. It would completely change her character dynamics. She could use it to enhance her medical ninjutsu, seeing the internal body structure more clearly. Also, she could become a more formidable fighter, using Sharingan - based genjutsu to her advantage.
In fanfiction, Naruto could get the Sharingan through a blood - related connection that is revealed later. For example, it could be discovered that he has some distant Uchiha ancestry that gets activated somehow. Maybe a powerful enemy's attack awakens this dormant Uchiha blood in him, and as a result, he develops the Sharingan. It could also be that a powerful sage or a new character uses their own unique powers to bestow the Sharingan upon Naruto for a specific purpose.
In a Highschool DxD OC and Sharingan fanfiction, you can incorporate the Sharingan powers in the story by making it a source of mystery and envy among the other characters. The OC could use the Sharingan's ability to enter the minds of others (a more advanced form) to gather information about the devils' plans. This would make the OC a valuable asset to their group. Also, the Sharingan could have a connection to some ancient prophecy in the Highschool DxD world, which would add more depth to the story and make the powers more significant in the overall plot.
Naruto might adapt by first trying to understand the basic functions of the Sharingan. He could start with the simple ability to see chakra flow more clearly. Since he has always been perceptive about people's emotions, he could use the Sharingan to read the emotions of his enemies through their chakra, which would help him in battles.
It could be Sasuke. In many Naruto - related stories, Sasuke has the Sharingan and is often the target of others' tricks or manipulations due to his complex personality and his power.
