One challenge could be the physical strain. The Harashin technique might require a different kind of chakra control and physical movement than what Naruto is used to. For example, it could demand more precise and rapid movements, which might be difficult for Naruto at first.
In some cases, Naruto could be in a really tough battle where he realizes the need for a super - fast movement technique like Hiraishin. So, he starts to search for ways to learn it.

The Naruto learns Rasengan fanfic can take the story in various directions. One direction could be a more in - depth exploration of the Rasengan's origin within the context of the fanfic.
