One possible plotline could be Naruto receiving special powers or blessings from Inari that enhance his already existing abilities. For example, it might give him an edge in battle against tough opponents.
In such a fanfic, Naruto might gain some special powers. Since Inari is associated with good fortune in the Naruto universe, this blessing could enhance Naruto's abilities, like making his Rasengan even more powerful. Maybe it would also give him an edge in battles against stronger opponents, as the blessing could bring him extra speed or strength.
His sense of responsibility would likely grow. Since the blessing is something special, he would feel a greater obligation to use it for the good of the village. He might start training harder to fully utilize the power of the blessing and protect those he cares about. He could also become more patient as he tries to understand the full extent of the blessing and how to best use it in different situations.
A mentor - mentee relationship could develop. Naruto has a lot of experience and skills, and Inari is young and eager to learn. Naruto could guide Inari in his ninja journey.
