Gon and Killua have finally made it inside the world of Greed Island, their clue to finding Ging. However, all they found was a message from Ging telling Gon to enjoy the game. Their first step is to find a city and gather information. There, they receive an invitation to join a group that's trying to clear the game.

Gon and Killua set off for Masadora in search of spell cards. On the way, they run into many different monsters. However, they struggle against some of the stronger monsters. A girl named Biscuit watches as they fight their way through.

Gon and Killua have finally realized Biscuit's true strength and asked her to teach them Nen. With that said, they begin their hard training.

Gon and Killua are gradually improving their Nen under Bisky's tutelage. They are now able to easily capture the monsters that they previously struggled against. While their training draws to an end, the Bomber is paying a visit to the players who have teamed up.

After hearing Bisky's lecture on rock-paper-scissors, Gon decides to work on a special technique modeled off of rock-paper-scissors by using Enhancer, Emitter, and Conjurer abilities. Meanwhile, Killua leaves the game temporarily to take the HUnter Exam. While he's gone, Gon and Bisky find learn about the Bomber's most recent attack.

Killua returns after easily passing his second try at the Hunter Exam. Now that Gon, Killua, and Bisky are together again, they begin working on beating this game by collecting cards. Meanwhile, the other players are scheming to gather the cards they need to complete the game.

Team Genthru now has 96 different types of restricted slot cards after tricking Team Tsegzerra. Gon and Killua receive an invitation from other players to team up to prevent Genthru from beating the game. They head to Soufrabi to monopolize Patch of Shore, one of the cards Genthru is missing.

The condition for obtaining Patch of Shore is to chase a band of fifteen pirates out of town. Gon and crew are immediately taken to the boss, Razor, but they are quickly defeated. The plan is to recruit stronger party members and try again, so they start with the player named Chrollo.

Gon and his friends have teamed up with Hisoka and Goreinu to challenge Razor again. To round out the party, they recruit Team Tsezgerra. Their preparations allow them to breeze through the first few matches, but then Razor challenges them to a game of dodgeball.

Gon is unable to hold onto Razor's throw and is sent to the outfield. He uses Back to return, but Hisoka is also injured and the situation looks grim. However, Gon has an idea for defeating Razor, but he needs Killua's help to pull it off.
