In fanfiction, it could be due to a prophecy. Suppose there was a prophecy that Naruto would bring great danger to the village in the future. Tsunade, despite her bond with Naruto, might believe in the prophecy and banish him to prevent the foreseen disaster. Also, it could be related to Naruto's power. If his power was growing too rapidly and becoming uncontrollable, Tsunade might banish him to protect the village from any potential harm his power could cause.
One possible reason could be political pressure. Maybe some powerful clans in the village see Naruto as a threat due to his growing power and influence. They might force Tsunade's hand to banish him to maintain their own status quo in the village.
Naruto could also become angry. He might feel betrayed by Tsunade and the village. This anger could fuel his determination to prove his innocence or worth. He could set out on a journey to become even stronger, so that one day he could return and show everyone that they were wrong to banish him. He might also start to question his own beliefs and values, which have been centered around the village and its people.
He could become determined to prove his innocence. Naruto is not one to give up easily. If he was wrongly banished, he would set out on a journey to find evidence or the real culprit to clear his name and return to the village he loves.
In this kind of fanfic, Naruto might go on a journey of self - discovery. He could end up in new lands, meet different people and learn new jutsu. Maybe he'll find a group that accepts him unconditionally and he grows stronger away from Konoha.
There could be. Fanfiction writers often come up with all sorts of interesting and unexpected relationships in their works. Given that both Naruto and Tsunade are important characters in the Naruto universe, a writer might have decided to create a story where Naruto is Tsunade's grandchild to explore new storylines, character development, and the impact on the existing Naruto world. It would likely involve a lot of creativity in terms of how their relationship affects the plot, the other characters, and the overarching themes of the Naruto story.
If Tsunade kisses Naruto, it could strengthen their relationship in a mentor - like way. Naruto might see it as a sign of deep respect and trust from Tsunade. He would likely feel more confident in following her guidance. For Tsunade, it could be a way of showing her pride in Naruto's growth.
Naruto might also initially feel a sense of abandonment. However, his kind - hearted nature could lead him to try and see the good in the situation. He could start to explore the world outside, learning about different cultures and ninja techniques. He may use this experience to become more empathetic towards others who have also faced hardships, and in the long run, this banishment could be a turning point in his life to become an even greater ninja.
At first, Naruto is probably shocked and confused. He might not understand why the village would take such a harsh step just for hurting Sasuke. He may feel betrayed, especially if he thought he had friends and allies in the village.
