Well, in this 'naruto son of hela fanfiction', it could be that the author is trying to combine the Naruto universe with the concept of Hela. Maybe it's about Naruto having some special powers or a destiny related to being the son of Hela.

You could try looking on popular fanfiction websites like FanFiction.net or Archive of Our Own (AO3). These platforms usually have a wide variety of fan - created stories, so there's a chance you'll find the 'naruto son of hela fanfiction' there.
One good Naruto Hela fanfiction could be 'Naruto and Hela's Alliance'. In this, Naruto might find common ground with Hela, perhaps in their pursuit of power in different ways. They could team up against common enemies in the Naruto universe and the world of Asgard.
Well, perhaps the plot could involve Harry having to deal with the dual nature of his heritage. He might inherit Thor's strength and Hela's connection to the darker aspects of magic. Maybe he has to face off against enemies that are threatened by his unique lineage and the power it could bring. He could also struggle with fitting into both the wizarding world of Harry Potter and the Norse mythology - influenced world of his parents.
One idea could be that Hela, being a powerful Asgardian, somehow gets transported to the Naruto universe. She could initially see the ninja as weaklings but then be impressed by their unique chakra abilities. For example, she might be intrigued by Naruto's Nine - Tails chakra and see it as a power source similar to her own in a way. Another plot could involve Naruto having to team up with Hela to fight a common enemy that threatens both their worlds, like an ancient evil that can cross dimensions.
One possible plot could be that Hela somehow gets transported to the Naruto universe. Naruto, being the curious and kind - hearted ninja he is, tries to understand her and her powers.

It's hard to say precisely without more context. 'naruto son of fanfiction' could be about a lot of things. It could be a story where the focus is on the relationship between Naruto and his son in a fan - created plot. This might include the son's journey to discover his own identity, his training, and how he copes with the legacy of his father.

Well, I don't really follow 'Naruto and Hela lemon fanfiction' directly. However, when looking for such fanfics, you should first make sure the website you're using is reliable. Some platforms have a better curation of crossovers. You could also check if there are any fan communities dedicated to this specific crossover who might be able to point you in the right direction.
One idea could be that Harry discovers his true mother is Hela and has to deal with the new identity. He might face discrimination from some in the wizarding world who fear Hela's reputation.
