For Naruto, he would likely gain a new level of understanding about the Uchiha. His view of the Sharingan and the power it holds might change. He could also develop a more nuanced approach to dealing with enemies, as Mikoto might teach him some of the Uchiha's battle strategies.
Mikoto herself would also experience character development. As she teaches Naruto, she would have to adapt her teaching methods to suit his unique learning style. This could make her more patient and flexible. Also, seeing Naruto's determination and his different way of thinking might make her re - evaluate some of her own clan's beliefs and values.
Hanabi could become more confident. With Naruto's training, she might start believing in her abilities more. For example, if Naruto encourages her during tough training sessions, she'll feel more self - assured in her skills.
The plot could involve Mikoto training Naruto to face the threats that the Hidden Leaf Village is facing. She might see Naruto's potential and decide to groom him into a great ninja who can protect the village. This could include sending him on special missions, teaching him strategic thinking, and how to work in a team. Along the way, Naruto could learn about the history of the Uchiha clan from Mikoto, which could be relevant to the overarching plot of the fanfic, perhaps related to some ancient threats or secrets that the Uchiha were guarding.
The plot might involve Mikoto helping Naruto understand the Uchiha clan better. Since she was part of the clan, she could share the history and values of the Uchiha with Naruto. This would not only strengthen Naruto's understanding of his comrades but also give him new perspectives on handling power and loyalty. For example, she could teach him how the Uchiha's Sharingan was related to their emotions and how to use that knowledge in battles.
Naruto can also be a great character in these fanfictions. His determination and his ability to grow under Mikoto Sensei's guidance make him stand out. He often has a lot of room for development in these stories, learning new skills and becoming more mature.
Naruto would likely become more powerful. With the Yin Kurama, his combat abilities could increase significantly. He might also become more mature as he has to deal with the added responsibility of this new power. For example, he would need to be more cautious in using it so as not to harm others accidentally.
He might develop new relationships. Since he's de - aged, he could make friends with people who he didn't interact much with before. For example, he could befriend some of the younger ninjas in a different way and learn from them too. This could change his perspective on teamwork and friendship.
For Naruto, he could develop more patience as a teacher. Teaching Konohamaru would be different from his normal ninja duties. He'd have to slow down and really explain things, which would help him grow as a person. Also, he might start to see himself more as a mentor figure in the village, not just a powerful ninja.
Being Mikoto's apprentice might also give Naruto a different perspective on life. Mikoto could share her wisdom and experiences with him, which would help him grow not just as a ninja but also as a person. Her teachings could influence his leadership style if he becomes Hokage in the future, making him more empathetic and well - rounded.
A really cool 'Naruto Mikoto Sensei' fanfiction could revolve around Mikoto Sensei forming a special team with Naruto and some other misfit ninjas. Together, they go on missions that are off - the - beaten - path and face challenges that require them to think outside the box. Mikoto Sensei's wisdom and experience guide the team through these difficult situations, and they all grow as ninjas and as people.
In this fanfic, a plot development could be that Mikoto arranges for Naruto to have more interactions with the Uchiha clan members. This could lead to Naruto learning about the Sharingan in a different way than in the original story. Also, Mikoto might be involved in Naruto's training to become a Hokage. She could teach him about leadership from an Uchiha perspective. Additionally, she could be the one to reveal some secrets about Naruto's parents that were previously unknown, which could change the course of his journey.
