Hunters are specialized in a wide variety of fields, ranging from treasure hunting to cooking. They have access to otherwise unavailable funds and information that allow them to pursue their dreams and interests. However, being a hunter is a special privilege, only attained by taking a deadly exam with an extremely low success rate.

Gon Freecss, a 12-year-old boy with the hope of finding his missing father, sets out on a quest to take the Hunter Exam. Along the way, he picks up three companions who also aim to take the dangerous test: the revenge-seeking Kurapika, aspiring doctor Leorio Paladiknight, and a mischievous child the same age as Gon, Killua Zoldyck.

As the four aspiring hunters embark on a perilous adventure, they fight for their dreams while defying the odds.

Hunters devote themselves to accomplishing hazardous tasks, all from traversing the world's uncharted territories to locating rare items and monsters. Before becoming a Hunter, one must pass the Hunter Examination—a high-risk selection process in which most applicants end up handicapped or worse, deceased.

Ambitious participants who challenge the notorious exam carry their own reason. What drives 12-year-old Gon Freecss is finding Ging, his father and a Hunter himself. Believing that he will meet his father by becoming a Hunter, Gon takes the first step to walk the same path.

During the Hunter Examination, Gon befriends the medical student Leorio Paladiknight, the vindictive Kurapika, and ex-assassin Killua Zoldyck. While their motives vastly differ from each other, they band together for a common goal and begin to venture into a perilous world
