Hunter x Hunter, Vol. 24 (Hunter x Hunter, #24)

Hunters are a special breed, dedicated to tracking down treasures, magical beasts, and even other men. 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.

1: Part 4
With the King preoccupied with playing Gungi, Gon and the other Hunters get closer and closer to their target. An unforeseen accident results in the deactivation of Neferpitou's En, making the defenses surrounding the castle temporarily vulnerable. The Extermination team readies for their showdown with the King, but with only a few days left before the "selection," will they be in time to save all the citizens from turning into Ant soldiers?!
