In many 'Naruto Exiled from Konoha' fanfictions, the Akatsuki members could be involved. They might view Naruto as a valuable asset now that he's an outcast from Konoha. Naruto could either befriend some of them, like Pain, who sees Naruto's potential and decides to help him in his exile, or he could be constantly on the run from them as they try to capture him for their own purposes.
Iruka sensei is almost certain to be in it. He has always been important in Naruto's life. Also, Sakura might be there. She could be one of the first to welcome Naruto or perhaps she might initially be a bit cold because of her past feelings for Sasuke. Other characters like Kakashi sensei could also make an appearance, guiding Naruto in his new life in Konoha.
One important character he could meet is the Raikage. The Raikage might initially be hostile towards Naruto due to his being from Konoha, but later sees his potential. Another could be Killer Bee. Maybe Killer Bee becomes Naruto's mentor in some ways, teaching him about the power of the tailed beasts in the Cloud village's perspective.
One interesting plotline could be Naruto's journey of self - discovery in exile. He might meet new allies who help him harness his powers in ways he couldn't in Konoha. Another could be his attempts to prove his innocence or show Konoha what they lost by exiling him.
One reason could be false accusations. Maybe some powerful individuals in Konoha frame Naruto for a serious crime he didn't commit. For example, they could plant evidence that he was involved in a plot against the village leaders. Another reason might be the fear of his power. If his strength grows too rapidly and uncontrollably in the fanfiction, the elders or some conservative forces in Konoha may decide to exile him to prevent any potential disasters. Also, political intrigue could play a part. If there are different factions vying for power in Konoha and Naruto becomes an obstacle or a scapegoat for one of them, they could manipulate the situation to get him exiled.
One possible reason could be that he is wrongly accused of a serious crime against the village. For example, if some important secrets are leaked and the village leaders suspect Naruto without proper investigation, they might exile him to safeguard the village's so - called security.
Iruka could be one of the characters. He has always been important to Naruto, and he might try to help Naruto or at least be concerned about his exile. Kakashi could also appear. He has a connection to Naruto and might be conflicted about the situation. And then there are Naruto's friends like Sasuke and Sakura. Sasuke might understand Naruto's feeling of being an outcast more than others, and Sakura could be torn between her loyalty to the village and her friendship with Naruto.
In this fanfiction, Naruto might find allies among the shinobi who were also wrongly exiled from their own villages. They would share a common bond of being outcasts and would fight together against the system that exiled them. Additionally, there could be some rogue ninja with a sense of justice who believe in Naruto's cause and decide to stand by his side in the war.
One possible reason could be political intrigue. Maybe there are some within Konoha who fear the power she might possess as a female Jinchuriki. They could spread false rumors about her being a threat to the village's stability, leading to her exile.
Jiraiya could be another one. Since he was Naruto's mentor, he might go after Naruto when he's kicked out and continue to train him in secret.
At first, she might struggle with loneliness. However, she gradually learns to rely on herself. She could set out on a journey to prove her innocence if she was wrongly accused. Along the way, she may face many challenges but use them as opportunities to grow. She might also find a new purpose, like protecting the weak in areas not covered by the major ninja villages, and in doing so, build a new reputation for herself.
