Hunter X Hunter. Volumes 19, 20, 21

Plucky Gon's quest to find his dad leads him into a whole world of crazy adventure. 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. Welcome to NGL (Neo-Green Life), a country led by an eco-group that's against all technology! No metal, synthetic material, or modern tools are allowed, and death is considered "nature's will." But a secret and powerful drug cartel operates within the country, and the queen of the Chimera Ants begins feasting on human flesh! Can Gon and his friends quash the queen's hunger before she gives birth to the dreaded king?
