His closest friends like Sakura and Shikamaru would be very interested. Sakura, as she has been through a lot with Naruto and always cared about his well - being. Shikamaru, because he is intelligent and would want to understand Naruto's motives and past experiences better to strategize better in future situations.
Iruka - sensei would be extremely interested. He was one of the first people to truly believe in Naruto. Seeing Naruto's memories would give him a deeper understanding of how Naruto overcame all the hardships and grew into the great ninja he is. It would also be a very emotional experience for him.
Well, one possibility could be that Naruto shows his memories to his friends to make them understand his past struggles better. For example, he might show them his lonely childhood, how he was ostracized by the villagers. This could lead to a deeper bond among them as his friends truly empathize with his journey.
The teachers would probably be very interested. For instance, Professor McGonagall might want to see Hermione's memories to understand her learning process better, so she can use that knowledge to teach other students more effectively. Also, Harry and Ron would be interested. They are her closest friends, and seeing her memories could give them a deeper understanding of her and their shared adventures.
She might be shocked. Naruto has had a really tough life and seeing all those memories of his loneliness, the villagers' hatred towards him when he was a kid, and his constant battles would be overwhelming for her. She could become more protective of Naruto, seeing him in a new light as someone who has overcome so much.
Naruto and Ace are the obvious main characters. Naruto as the protagonist of his own world, and Ace whose memories are the central theme. However, it's possible that the fanfic also focuses on some of the antagonists from Naruto. For instance, Orochimaru might be interested in Ace's memories for his own evil purposes. This could lead to new conflicts and alliances within the story. Additionally, side characters like Shikamaru might be involved as they are often used to provide different perspectives and strategies in the Naruto series.
Hinata would also be highly affected. She has always admired Naruto from afar. By seeing his memories, she would understand him on a whole new level, his struggles, his hopes, and it would likely strengthen her feelings for him even more. And it could also change how she interacts with him in the story.
His relationships with his friends like Sasuke and Sakura would be deeply affected. They might feel like they've lost a part of Naruto. Sasuke, for instance, might initially be frustrated as he's used to Naruto's determination. Now, with his memories gone, Naruto might seem like a different person to Sasuke.
It could strengthen his bond with his family. Since Kushina was his mother, having her memories might make him understand her better and also feel closer to his father, Minato. He would know the love and sacrifices they made for him, which could make him more protective of the family name and legacy.
Obviously, Naruto fans who also like cats would be interested. People who enjoy reading fan - made stories that add a unique twist to the original Naruto universe might also be into it.
Harry's memories in fanfiction can really stir things up for the other characters. His memories of growing up with the Dursleys, for instance, might make some characters feel sorry for him and more inclined to offer him a real family - like the Weasleys might become even more motherly and fatherly towards him. And his memories of battles and narrow escapes can give the other characters valuable insights into the tactics of the enemy. They could use this knowledge to better prepare for future confrontations. In a way, Harry's memories are like a key that unlocks a deeper understanding among his comrades.
He might become more confident. Knowing more about his family from his mom's memories could give him a sense of pride and belonging, which would boost his confidence.
