One possible plot could be that Naruto, in a state of extreme emotional distress, starts self - harming. Itachi, either in a vision or some spiritual form, tries to reach out to Naruto. Naruto, influenced by Itachi's presence, decides to leave his current situation. Maybe he leaves the village to seek solitude and heal. It could also involve Naruto learning some of Itachi's wisdom during this journey and gradually overcoming his self - harm tendencies.
Perhaps the fanfic could start with Naruto being bullied or feeling extremely lonely. His self - harm is a cry for help that no one in the village seems to notice. Itachi, who has always been a complex and mysterious character, appears to Naruto. Itachi shows Naruto his own past struggles and how he coped. This makes Naruto realize that he needs to change his environment. So, he leaves the village with the idea of finding a new purpose and a way to stop harming himself.
Itachi is known for his deep understanding of human nature. He could analyze Naruto's self - harm behavior and help Naruto see the root causes. By being a guiding figure, Itachi could lead Naruto on a journey of self - discovery. For example, Itachi might take Naruto to places that are important to his own past, and through these experiences, Naruto learns to value his life more and stop self - harming.
Maybe Itachi, despite his stoic nature, starts to have an unexpected soft spot for Sakura. He could be secretly protecting her during her missions, which might lead to some tense and mysterious moments as Sakura tries to figure out who her mysterious protector is.
One possible plot development could be Naruto leaving due to a misunderstanding. For example, if he is wrongly accused of a crime within the team. Another could be that he feels he is holding the team back in some way and decides to leave on his own to become stronger alone. Maybe he has a personal goal that he believes he can't achieve while still being part of Team 7.
Well, Naruto could leave the village in a fanfic due to a prophecy. He might believe that leaving is the only way to fulfill a greater destiny that the village can't support. As he leaves, he starts to explore different cultures of the ninja world. He learns about new forms of jutsu and how other villages operate. He could also form a team with outcasts from different villages, and together they strive to change the way the ninja world views things.
Maybe Percy leaves the hunt because he has some personal issues to deal with. For example, he might have a family matter that requires his full attention. Or perhaps he has a different mission or goal in mind that conflicts with the hunt.
One possible theme could be the struggle with mental health. Both characters might be dealing with their own demons, and self - harm could be a visible sign of that internal battle.
Such fanfics can have a negative impact on the Naruto fandom as a whole. They can create an uncomfortable and disturbing atmosphere. Also, it might mislead younger fans who look up to the Naruto characters and think that self - harm is something that can be associated with the story. In the real Naruto story, the characters face difficulties but in a positive and healthy way, not through self - harm. So these fanfics can be a misrepresentation.
A plot could be that Itachi fakes his death earlier and joins Naruto's side. They travel together, with Itachi using his intelligence and skills to guide Naruto in his journey to become Hokage. They encounter various villains and challenges along the way. Itachi's experience and Naruto's enthusiasm complement each other well, making them a formidable team.
Well, the plot could involve Itachi having to deal with the power of the tailed beast within him. Maybe he has to constantly struggle to control it while still maintaining his calm and collected exterior. He could use the power in unexpected ways to protect his village or those he cares about, like Naruto does with the Nine - Tails.
In a 'Naruto Namikaze leaves Konoha' fanfic, it could be that Naruto is framed for a crime he didn't commit. The villagers turn against him, and even his friends start to doubt him. Feeling betrayed and alone, he decides to leave Konoha. As he travels, he meets other outcasts who have also been wrongly accused, and together they form a group to clear their names and seek justice.
