HxH is the second best story out there (Yu Yu Hakusho is #1 for me). Togashi is a genius when it comes to writing well-balanced and well-developed characters, whether protagonist or antagonist.
Anyways, the story is about a kid, Gon, who wants to become a Hunter like his dad. As a Hunter, Gon wants to find his Hunter dad. The story is hardly about that, though. It's more about the relationship between Gon, a friend he meets (Killua), and somewhat Kurapika and Leorio. Just watch it. There's too much to explain.
Also, if you like Naruto, you'll absolutely love HxH, mainly because Kishi took many of the ideas/characters from HxH. However, Togashi knows how to write a good story with amazing characters , as opposed to Kishi.
