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.

In an unexpected turn of events, Gon, Killua, and their sometime enemy Hisoka pull off a stunning victory in a heated game of deadly dodge ball, working together to defeat Razor and his 14 Devils. Meanwhile, a group of rival Hunters zap out for a meeting with the billionaire benefactor who has hired numerous hunters, including Gon, to solve the Greed Island game. There they make a shocking discovery that may very well make all of their struggles meaningless!
