The game Greed Island, which holds a clue to finding Ging, is finally on auction. Gon and Killua ask the winning buyer to hire them as players, but they're told that their Nen is too weak. They begin to work on special abilities so they can be selected as players.

Gon and Killua are trying to get themselves chosen as Greed Island players. Tsezgerra, the judge, says that he will make his decision after they show him his Nen. Only 32 of the 200 applicants will pass.

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.

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.
