Since I don't have detailed information about 'shinju no nectar light novel', it could potentially be a story centered around some kind of special nectar in a fictional realm. Maybe it has elements of magic or mystery associated with this nectar, and characters are on a quest related to it.

Since the Shinju is a very powerful and mysterious entity in the Naruto universe, consuming it might endow Naruto with abilities beyond his normal limits. Maybe he could gain control over new types of chakra or even have a better understanding of the origin of all things in the ninja world.
He might be desperate. Maybe there is a great threat to the ninja world that can only be defeated by the power of the Shinju. Naruto, being the hero he is, decides to take the risk of eating it in order to gain the power needed to save everyone.

But generally, Prabhupada's stories often revolve around the teachings of the Bhagavad Gita, like stories of the Pandavas and Kauravas to illustrate the concepts of dharma (righteousness) and karma (action and its consequences).
One idea could be to write a fanfic about an alternate adventure where Aru and her friends encounter a different set of challenges on their quest for the nectar of immortality. Maybe they face a new villain who has a unique power that they have to figure out how to overcome.
