I wonder if you'll update again. But I want to mention a few illogical things.
I understand that you don't know much about Nen. The first is that Wendy couldn't see Illumi's aura in your first book, which makes sense because she's not a Nen user. But suddenly, later in the story, she can see the Nen aura. One could argue that the magical core is connected to life energy, but then it's illogical that she couldn't see it with Illumi.
2. Nen and chakra aura, are the same, but a different system. Nen and chakra are a person's life energy. It was illogical that Gon couldn't see the wires in your Chunin book. Because it was with chakra, i.e., life energy, Gon would be able to see it with "Gyo." And one more thing: Gon and Killua would be able to see the chakra glow with Gyo, like with the Byakugan. With Gyo, you can see the inner Nen aura, which is life energy, like with chakra.
3. Ten is the heavier version of Ken. Ren is where they unlock their aura. If you continue, you could add more characters from Fairy Tail and change the arc's story.
No hate, because the crossover story doesn't change the story of Naruto or Hunter at all. It's like the original with a few changes, which isn't a big deal.
