Hunter x Hunter, Vol. 7: Volume 7  (English, Paperback, Togashi Yoshihiro)

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 diligently studying the ways of Nen with master Wing at Heavens Arena. When Gon successfully completes the Nen teachings, he also passes the final (and secret) test of the Hunter Exam. But more importantly, Hisoka has finally deigned to accept Gon's challenge! Can Gon get close enough to pay Hisoka back for the favor on Zevil Island, or will the insane magician send Gon home in pieces?
