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 are so incompetent at fighting the monsters on Greed Island that a Hunter named Biscuit has taken pity and offered to coach them in the use of their Nen powers. But the clock is ticking, for a violent player known as "the Bomber" has a plan to get his hands on all but ten of the item cards in one fell swoop.
