First of all, his friends would likely be very curious. Since Naruto has had a rather eventful childhood, the fanfiction could contain a lot of personal elements. They might be amused by his childish handwriting or the simple way he used to express his ideas. Some might even be touched if the fanfiction reveals Naruto's hidden insecurities or hopes from back then. It could also lead to his friends having a new perspective on Naruto, seeing a side of him that they didn't know before.
His friends might be shocked at first, but then start to really enjoy reading it and discussing the ideas in it.
In many such fanfictions, when Naruto gets his inheritance, he often gains new and powerful abilities. For example, he might inherit some unique jutsu from his ancestors. This could make him even stronger than he already was in the original series, allowing him to face tougher opponents with ease.
In this fanfiction, Naruto might face various challenges while claiming his inheritance. It could involve dealing with hidden secrets about his family, perhaps some sort of special jutsu or a powerful item left behind. Maybe there are other characters who oppose his claim, leading to battles or political intrigue within the Hidden Leaf Village.
One common way is through loyalty. He'll always stand by his brother no matter what. Another is by listening. He gives his brother his full attention when he has something to say.
Boruto might be in awe. He would probably look at Naruto with wide - eyed wonder, realizing just how powerful his father is.
One possible reason could be that Naruto is afraid of endangering his friends. He has many powerful enemies, and he might think that by staying away from his friends, they won't be targeted. For example, Orochimaru was always after Sasuke, and Naruto might fear that his closeness to Sasuke could put Sasuke in more danger.
In the context of fanfiction, it might also be a plot device to explore Naruto's vulnerability. It could lead to new character developments, such as others seeing him in a new light. Maybe it causes some characters to re - evaluate their relationship with him, while for others it could be a source of inspiration, seeing that even someone as strong as Naruto has his own set of hardships.
Well, it could lead to some intense action and drama. Maybe Naruto uses his ninja skills to protect his sister and fight off the assassin.
He might show his scars to Sasuke. Given their complex relationship, it could be a powerful moment between them, a way to show Sasuke that Naruto has also faced great pain in their separation and the events that followed.
