An author's introduction would usually appear in the introduction of the novel or in the biography of the character to provide the reader with some information about the background of the novel and the character.
A common author introduction included:
- Name:XXX
- [Male/Female]
- Country: China/United States
- Profession:
- Representative works: "XXXXX","XXXXX"
- Experience:XXX
For example, the author of "Battle Through the Heavens", Tian Can Tudou, was a Chinese author. His representative work,"Battle Through the Heavens", had won many literary awards. His personal experience was also very rich. He had held various positions such as network, editor, and director.
In addition to introducing the author's name, gender, nationality, occupation, representative works, and experience, some authors would also mention their creative philosophy, literary style, and creative process. This information can help readers better understand the author's writing style and characteristics, so as to better read their works.
One possible reason could be the burden of his past. Naruto has faced a lot of hardships and the memories might be overwhelming him, making him want to be alone. For example, the loss of his master Jiraiya might have left a deep scar, and he might feel that isolating himself is the only way to deal with that pain.
Maybe he feels a sense of guilt. For example, if something bad happened in the village that he blames himself for, even if it wasn't really his fault. He could exile himself as a form of self - punishment. He has always been very hard on himself when it comes to the well - being of the village and his friends.
In some versions of fanfiction, Naruto might use a new and powerful sealing jutsu that he has either created or learned specifically for this purpose. It could be a jutsu that combines his Uzumaki heritage's sealing knowledge with his own unique chakra control.
Author introduction:
This was a person's name. It could be the author of the novel, or it could be the novel's critic, editor, or translator. A person's name usually begins with a surname and is followed by one or more first names. For example, Xiao Ding was the author of Celestial Bane, Qian Lei was the critic of Border Town, and Zhao Shuli was the editor of Red Rock.
One challenge is controlling the amount of natural energy. It's not easy to find the perfect balance. Too much and he could turn into a statue or something similar. Another is that he doesn't have a proper teacher to correct him immediately. He has to rely on his own instincts and the limited knowledge he has about senjutsu.
Jiraiya could still play a role. Even if Naruto is raising himself, Jiraiya might cross paths with him and see his potential. He could offer some sporadic guidance without fully taking Naruto under his wing.
Well, while there might be some out - of - character fanfictions out there, the general perception of Naruto is that he is a very selfless character. His whole journey in the original story is about protecting others and achieving peace for everyone. So, in fanfiction, it's not very common for him to be portrayed as only caring for himself. Usually, the essence of his character is maintained, which is his altruism.
