Hunter x Hunter Vol. 16 (manga)

Gon and friends are settling into Greed Island and slowly beginning to understand the strange mechanics of this "video game" world. They gain enough clues from the NPC townspeople to finally get their quest: They must drive Razor and the 14 Devils out of town by beating them at sporting events. The first event--dodge ball! Except in this game if you don't dodge--you die!!
