Along the way, he might have to face enemies who want to destroy the Shinju for their own gain, and he'll have to use his new - found connection to the Shinju to fight them.
It's possible that the fanfiction explores a world where Naruto is actually a part of the Shinju, like he was born from it or has its essence within him. This would completely change his relationship with the other characters. His friends might be confused or even scared at first, but then they realize that Naruto's connection to the Shinju is for the greater good.
