Hunter x Hunter (3-in-1 Edition), Vol. 3

Hunters dedicate their lives 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 earn the right to call themselves Hunters. Gon and Killua are diligently studying the mysterious ways of Nen with Master Wing at Heavens Arena. When Gon successfully completes the Nen lesson, he also passes the final (and secret) test of the Hunter Exam.
