Another reason might be that he has some internal conflict. For example, he could be doubting the purpose of the training. If he doesn't see a clear goal or if he's starting to question the methods, he might refuse. In some fanfics, he could also be influenced by new friends or ideas that make him question the traditional ninja training regime.
One possible reason could be Naruto's independent nature. He has always strived to make his own path and not rely on his father's legacy too much. So in the fanfic, he might refuse Minato to show that he wants to be his own person, not just Minato's son.
Well, the result might be a fanfic that better adheres to the Naruto universe's rules and lore. For example, if the training focused on jutsu usage, the fanfic could then accurately describe how Naruto or other characters perform their jutsus. It could also result in a more immersive experience for the readers as the writing style gets polished during the training process.
In the original Naruto story, the training is more in line with the established ninja academy and traditional Sensei - student relationships. But in 'naruto training lemon fanfic', it might be more experimental. Maybe Naruto tries some unorthodox methods of training that are not seen in the original.
Well, the main characters are Naruto Uzumaki and Jiraiya. Naruto is the protagonist of the Naruto series, a ninja full of energy and a strong will. Jiraiya, on the other hand, is a powerful and well - known ninja. He is Naruto's mentor in this fanfic, guiding him through various training regimens and sharing his knowledge and experiences.
Obviously, Naruto is the central character. But there are also often other characters like Jiraiya. Since Jiraiya was Naruto's mentor in the original story and had knowledge about sage mode, he often appears in fanfics to guide Naruto in his training. Another common character could be Kakashi. He may offer some advice or support to Naruto during the training process.
Sakura is often a popular character in these types of fanfics. Since she is a kunoichi herself in the original Naruto series, it's easy to write about her further training. Hinata can also be a main character, as her gentle yet strong nature can be explored more during kunoichi training.
Meditation could be added as a daily warm - up. Naruto could start his training by clearing his mind, which would help him focus better on the physical aspects later. For instance, before practicing his Rasengan, he meditates for a few minutes to get in the zone.
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.
