Plucky Gon's quest to find his dad leads him into a whole world of crazy adventure.

Hunters are a special breed, dedicated to tracking down treasures, magical beasts, and even other people. But such pursuits require a license, and less than one in a hundred thousand can pass the grueling qualification exam. Those who do pass gain access to restricted areas, amazing stores of information, and the right to call themselves Hunters.

Gon and Killua have split off from the rest of the group to spend the next six months training at Heavens Arena. But despite the skills they came in with, the friends are quickly outmatched by another young fighter who can access the mysterious power called "Nen." Nobody will hire a Nen-less Hunter, so Gon and Killua are determined to learn quickly. Do they have what it takes to become Nen masters?
