The theme of sacrifice could also be present. Kakashi has often put himself in harm's way for the sake of others, whether it was for his village or his friends. His willingness to sacrifice his own well - being for the greater good could be a strong theme in the 'kakashi's story novel'.
Another theme might be redemption. Given some of the events in his past, like his role in Obito's 'death', there could be elements of him seeking redemption or coming to terms with his actions. Also, the theme of growth is likely. He started as a young ninja and grew into a highly respected and powerful one, and the novel could show this journey of self - improvement.
Well, there could be themes like the reaction of the other characters in the Naruto universe. How would Naruto's friends, like Sasuke or Sakura, react to such a situation? Also, it could explore the relationship between Kakashi and Naruto on a deeper level. Since Kakashi is Naruto's teacher, this new situation would change their relationship in many ways. And the theme of dealing with the stigma or uniqueness of a male pregnancy in a world that may not be fully accepting of it could also be present.
The theme of impermanence is also very likely. Sakura blossoms are known for their short - lived beauty. In the novel, this could be reflected in the characters' lives, perhaps a relationship that is as fleeting as the sakura bloom, or a moment of happiness that is soon lost, teaching the characters to cherish the present moment.
In the fanfiction, Kakashi might fail because of external pressures. For example, he could be given other important missions that take up a lot of his time and energy. So, he can't dedicate enough time to Sasuke and Sakura's development. Also, he could be facing political pressure within the village that restricts his teaching methods or the resources he can use for their training. This would lead to him not being able to meet their needs and ultimately failing them.
One possible reason could be that Kakashi might be haunted by his past experiences. He has lost many comrades, and perhaps he's afraid that getting too close to Naruto and training him would put Naruto in danger as well. He might think that Naruto, being the Jinchuriki of the Nine - Tails, already has a target on his back, and training him would only make that target bigger.
One possible motive could be to help Naruto control the Nine - Tails' chakra better. Hypnosis might be a way to reach into Naruto's subconscious and find a way to coexist with the powerful force inside him.
A plotline could revolve around Sakura getting special training from Kakashi. He could pass on his unique skills and knowledge, like his lightning - style jutsu or his stealth techniques. This would make Sakura an even more formidable ninja and also strengthen their father - daughter bond.
One possible theme could be their rivalry. They are known for their friendly competition in the Naruto series. Fanfiction could explore how this rivalry started, how it evolved over time, and how it made them both better shinobi.
One possible theme could be their deep friendship. They could be shown supporting each other through tough times, like when facing a powerful enemy. Another theme might be their growth as ninjas. For example, they could train together and learn new techniques from each other.
In the fanfic, Kakashi might neglect Naruto's training due to a variety of reasons. He could be preoccupied with his own research or a secret mission that demands his full attention. There could also be a misunderstanding between him and Naruto. Maybe Naruto has done something that Kakashi misinterprets, causing him to distance himself from Naruto's training. Additionally, the fanfic could introduce new characters or plot elements that draw Kakashi's focus away from Naruto. For example, a new threat to the village that Kakashi feels he must handle alone, thus neglecting his duties as Naruto's trainer.
It could also be due to a misunderstanding. Kakashi might be keeping some secrets from Naruto, like information about his parents or some hidden power within him. Naruto, being curious and eager for answers, could misinterpret Kakashi's motives for secrecy as a sign of distrust or dislike, which then turns into hatred.
