Kurapica contracts a fever while Killua and Gon go to the auction but they do not buy the Greed Island game instead asking but asking the one bought it if they can play it.

Killua and Gon go to train individually for their ultimate technique so they can enter the Greed Island game. Killua manages to use his transformation ability to turn his aura into electricity while Gon develops power combining all of his Nen powers. Kurapica leaves on an airplane.

Gon and Killua have trained and go to do the "Greed Island player's exam" passing with flying colors. Then they say goodbye to Leorio and go to the castle from where they are able to enter the game. Gon goes first.

Gon finally finds out during the introduction what the save data on the disk Jin left is. Together Killua and Gon take their first steps into Greed Island. They meet a player who sets a "trace-card" on Killua so he can find him later to steal a card from him. Killua and Gon go to a town and get their first cards. During the game they see a man they saw during the "Greed Island player's exam" die from a mysterious bomb.

Gon and Killua are invited to join an alliance but decide not to and go on their own. The mistyrious girl follows them. They win their first card in a "Rock, Paper, Scissors" competition. It is card #83, "The Sword of Truth".

Gon and Killua continue playing, but the card they won gets stolen by some more experienced players. Members of the Genei Ryodan start to play the game with their stolen copy.

Gon and Killua continue to the city where you can get spell-cards. They meet monsters, bandits and more discovering that in a game like Greed Island they're not very skilled. Biscuit Krueger follows them and watches them getting frustrated with their lack of skill.

Gon, Killua and Biscuit (their female trainer) are attacked by Binolt, a bounty hunter. They subdue him and Biscui gives him a chance to live, using him to train the boys during a two week period.
