One possible plotline could be that Naruto discovers a new form of chakra that makes him nearly invincible. For example, he might find a way to combine sage mode with a special kekkei genkai he unlocks. This new power allows him to withstand attacks that would otherwise be fatal. Another could be that he makes a pact with some sort of powerful spirit or deity who grants him immortality in exchange for a great service. Maybe he has to protect a sacred place from being destroyed forever. And yet another could be that through some advanced medical ninjutsu research, he figures out a way to regenerate his body continuously, thus refusing to die.
Sasuke is an obvious choice. He has a connection to Naruto that goes beyond just friendship or rivalry. He might be the one who first discovers Naruto's predicament and sets out to find a solution. Sakura is essential too. Her skills as a medical ninja are crucial. She could be the one who patches Naruto up every time he gets injured in his fight against whatever is threatening his life. Also, characters like Jiraiya might make an appearance. Even though he's dead in the original story, in this fanfiction, he could come back as a spirit guide to help Naruto find a way to 'refuse to die', giving him advice based on his own knowledge and experiences.
One possible reason could be that Naruto has seen the toll the position takes on those who hold it. Maybe he witnessed the stress and loneliness that previous Hokages like his father had to endure. He might want a more carefree life, exploring the world and spending time with his friends and family without the heavy burden of leading the village.
Perhaps 'cra' stands for something specific like 'crazy' or an abbreviation for some other concept. Naruto refusing it might imply that the fanfiction contains out - of - character behavior for Naruto, such as making him act in ways that go against his well - established personality in the official story. For example, if the fanfiction makes Naruto suddenly become extremely cruel or cowardly when he is known for his determination and kindness in the original series.
It could also be that the plot of the fanfiction has Naruto in a situation where talking might put him or his loved ones in danger. So, for their safety and his own, he chooses not to talk.
Naruto might be initially very disappointed. He has always looked up to Jiraiya and expected to be trained by him. So, when faced with the refusal, he could be heartbroken and feel like he has lost a great opportunity.
Naruto might be initially very disappointed. He has always looked up to Kakashi as a strong and cool ninja, and being refused by him would be a big blow. He could become a bit sulky and withdrawn, feeling like he's not good enough.
One possible reason could be Naruto's independent nature. He has always been someone who forges his own path. In the Naruto series, he doesn't rely on traditional forms of status or hierarchy. So in the fanfiction, he might refuse peerage because he wants to be recognized for his own efforts and not because of a title.
One possible reason could be that Naruto is too focused on his ninja duties. He has always been dedicated to protecting the village and his friends, and marriage might seem like a distraction from that. For example, he has to constantly be on guard against new threats and train the next generation of ninjas.
There are also the wandering ninja. These are ninja who don't belong to any particular village. They might join forces with Naruto because they understand what it's like to be on the outside. Together, they could form a sort of 'rogue' ninja group.
