Gon, a young boy who lives on Whale Island, dreams of becoming a Hunter like his father, who left when Gon was still young.

(From Hunterpedia): Gon, Killua, and Leorio return to help Kurapika’s recovery after the battle against the Phantom Troupe. Leorio and Kurapika leave again, returning the focus to Gon and Killua. Gon and Killua are able to join a team hired by the billionaire, Battera, to play the game. Gon and Killua are joined and later Nen-trained by Biscuit Krueger, a 57-year-old woman who looks like a 12-year-old girl, and is a master and experienced teacher of Nen. As the story progresses, a player nicknamed the Bomber is blowing other players up. Gon, Killua, and Biscuit team up with other players and take the Bomber out. The Phantom Troupe also travels to Greed Island, looking for a Nen-Remover to remove the Nen dagger on Chrollo Lucilfer put by Kurapika to null his powers.
