This freedom often leads to very creative and engaging stories that draw in readers who are looking for something different from the original source materials.
The plot might involve Naruto being shunned by the Gremory family or their associates. This could lead to Naruto having to find his own path.

Together, they might form an alliance to change the perception of the Gremory family towards them or to simply make a place for themselves in this world that seems to not want them.
