They could leave Konoha together to search for Sasuke. Naruto still wants to bring Sasuke back, and Sakura, who also cares deeply for Sasuke, decides to accompany Naruto. On their way, they encounter different people who either help or hinder their search. They might also discover new things about Sasuke's past or the reasons behind his actions, which could add more depth to the story.
One possible plot could be that they leave to find a new way to strengthen Konoha. Maybe they've heard of a powerful jutsu or artifact outside the village that could enhance the village's defenses. They journey together, facing various challenges like difficult terrains and enemy ninja along the way. During their travels, they might also have deep conversations, strengthening their bond as friends and comrades.
One possible plot could be that they leave Konoha due to a new threat that the village is unable or unwilling to face. They might go on a journey to find a way to defeat this threat on their own. Along the way, they could face many challenges that test their friendship and skills.
One possible plot twist could be that they are being secretly manipulated by an unknown enemy who wants them out of Konoha for some dark purpose. Maybe this enemy has spread false rumors about them in the village, making them feel like they have no choice but to leave. Another plot twist might be that they discover a long - hidden truth about their families that is connected to some ancient power outside of Konoha, which compels them to leave in search of answers.
Well, in such a fanfiction, perhaps Naruto leaves Konoha after some internal conflict. The female Kyuubi could be a symbol of freedom for him. They might end up in a hidden land where they build a new community. Naruto could use his skills to protect this new place, and the female Kyuubi could use her powers to help the land thrive. Their relationship could be a mix of friendship and mutual respect, and they might attract other outcasts who also want to start anew away from the traditional shinobi world.
One possible plot could be that Naruto and Samui are on a mission outside Konoha when they receive some crucial information that puts Konoha in danger. However, they realize that there are traitors within the village who would stop them from using this information to save it. So, they decide to leave Konoha temporarily to gather more evidence and allies. Along their journey, they face various challenges and also start to understand each other better, with Naruto's determination rubbing off on Samui and Samui's calm and strategic thinking helping Naruto in different situations.
They might leave to seek new forms of power or knowledge. There could be things outside of Konoha that they believe will help them become better at their ninja skills. For instance, they might have heard of a special dojo or a hidden scroll in another land that could enhance their abilities.
One possible plotline could be that they leave to seek a new form of power. Maybe they've discovered a threat that the Hidden Leaf isn't aware of, and they believe they can find a solution outside. Another could be that they're on a journey of self - discovery. Sakura has always been in Sasuke's shadow to some extent, and this could be her chance to truly find herself while being with him. Also, perhaps they leave due to some political unrest in Konoha that they don't want to be a part of.
One possible plot could be that Naruto and Sakura are paired up for a school project. Naruto, being his usual enthusiastic self, wants to do something really grand while Sakura is more focused on getting a good grade. They start off bickering but as they work together, they discover new things about each other and their relationship deepens, much like in the original Naruto series where they grow closer over time.
One reason could be a sense of not belonging. In the village, Naruto faced a lot of discrimination because he was a Jinchuriki. As a female Naruto, she might face additional issues like gender discrimination. Maybe she feels that no matter how hard she tries, she will never be fully accepted in Konoha, so she decides to leave.
They could be leaving in search of new training opportunities. Konoha might not offer the advanced or specialized training they seek. So, they decide to leave to find a place where they can grow stronger and expand their abilities.
One reason could be to gain more power. In many fanfictions, Naruto realizes that the threats he faces are far greater than what he can handle with his current skills in Konoha. So, he decides to leave and train in a more secluded and challenging place to enhance his abilities.
