Sakura's development would involve a lot of self - discovery. She would have to come to terms with this new power that is not native to her. She might face some internal struggles about whether she truly deserves it or not. However, as she learns to master the Sharingan, she would grow into a more complex and powerful character, with a new understanding of the ninja world and her place in it.
Sakura would become more confident. With the Sharingan, she would have an edge in battles, and this would boost her self - esteem. She would no longer be just the 'healing ninja' but a powerful combatant too. Her relationships with Naruto and Sasuke would also change. She might be less in Sasuke's shadow and could even rival him in some aspects.
Sakura's character would develop in terms of her combat skills. The Sharingan would allow her to analyze her opponents' moves more quickly and accurately. This would also boost her self - esteem as she would no longer be seen as just a support ninja. She would start to take on more dangerous missions and grow as a leader within her team. For example, she could use the Sharingan to see through genjutsu more easily during battles, which would give her an edge. Additionally, she might develop a new sense of pride in her abilities that was not there before, as she now has a unique power that few others possess.
His sense of self - identity might be shaken. Ichigo has always been defined by his role as a Soul Reaper and his own unique powers in the Bleach universe. Adding the Sharingan would introduce a foreign element. He would have to figure out how this new power fits into his existing power set and his moral code. He might question whether he's still the same Ichigo or if this new power is changing him into someone he doesn't want to be. This internal struggle could lead to significant character growth as he grapples with his new identity.
Naruto's confidence would likely increase significantly. Having such a powerful and unique ability would make him feel more capable of protecting his village and friends. He might become a bit more reserved at first, as he tries to understand and master the new power, but eventually, he would use it to be more assertive in battles and in diplomatic situations as well, knowing he has an ace up his sleeve.
Naruto would likely become more introspective. The Rinne Sharingan is a very powerful and somewhat mysterious ability. Having it would force Naruto to understand more about the deeper aspects of chakra and the ninja world. He might become a bit more cautious as he realizes the great power he holds and the potential for it to be misused.
Sakura would likely become more independent. Running away from a marriage forces her to rely on herself. She would start to make her own decisions without depending on her spouse. For instance, she would have to figure out how to earn money, find shelter, and protect herself.
Naruto would likely become more introspective. The Sharingan often comes with a lot of emotional baggage in the Naruto universe. He might start to question his own identity more, since the Sharingan is so closely tied to the Uchiha clan. He could also become more cautious in battle, as he now has a power that can be both a great asset and a great danger if misused.
She would become more stealthy and less impulsive. Since ANBU work requires a lot of secrecy and patience, Itachi's training would force her to change her approach. She might start thinking more strategically and be less likely to jump into a fight without a plan. This could completely transform her from the somewhat brash character she was before.
During the training with Orochimaru, Sakura would probably experience a significant transformation in her character. Her medical skills might take on a new dimension as she learns from Orochimaru's knowledge of forbidden techniques. This could lead to her being more willing to take risks in the medical field for the sake of achieving greater results. Emotionally, she may become more detached as she gets used to Orochimaru's cold - hearted approach to training, but at the same time, she might develop a stronger will to protect her friends and village from the kind of evil Orochimaru represents.
If Sakura joins the Akatsuki in fanfiction, her character would likely become more self - reliant. In Konoha, she had friends and mentors to rely on. But in the Akatsuki, she would be among people who are not as trustworthy. This would force her to rely on her own skills and instincts more. Also, she might become more secretive. Since she's in a group that's not exactly friendly to Konoha, she'd have to keep a lot of things to herself.
Naruto's fighting style would evolve significantly. He would no longer just rely on his brute strength and the Nine - Tails' chakra. With the Eternal Mangekyou Sharingan, he could use powerful genjutsu and ninjutsu unique to the Sharingan. He might start to use more stealth and precision in his attacks. His training would also change as he has to master the new abilities. He would probably study Uchiha history and techniques more, which would make him more well - rounded as a ninja. This new power would also bring out a more serious side of Naruto, as he now has the responsibility of using such a powerful ability for the good of the village and the ninja world.
