I think a lot of people have heard about this anime as well as the manga.
[size=12]From AniDb.net:
Gon`s father, long believed to be dead, is still alive and was once one of the greatest Hunters in existance. Gon believes he will be able to meet his father once he himself becomes a Hunter. However, before he can become a Hunter, he has to pass the Hunter Exam first, an exam made of numerous tasks and dangerous trials. Persevering and refusing to give up, Gon manages to reach the Hunter Exam, all the while keeping his innocent attitude. Throughout many of the tasks and trials of the Hunter Exam, Gon manages to make many unique friends. Kurapica, a sole survivor of his clan seeking revenge, Leorio, who wants to become a doctor, and Killua, a member of an infamous assassin family, all eventually join up with Gon in hopes of passing the exam together. Each of them have their own reasons for taking the exam, but will they manage to pass it alive? It will be no easy task, as the tasks and trials in the exam are not easy. Aside from worrying about dying from the exam itself, Gon and his friends also have to watch out for killers participating in the exam.
