A few days later, Gon and Killua achieve their objective and begin playing "Greed Island", an extremely rare and expensive video game with Nen-like properties following some clues about Ging's whereabouts. While exploring the game, it is revealed that its scenario is actually set somewhere in the real world, created with Nen by a team led by none other than Ging himself. Outclassed by the difficulty of the challenges in the game at first, they are soon joined and trained by Biscuit Krueger, an experienced teacher of Nen and kung fu master. With the help of Biscuit, Gon and Killua train their Nen and learn to shape their abilities to their traits. During their stay on Greed Island, Killua takes a short break to apply for the Hunter Examination again, this time passes with success. The trio then complete the game together against all odds and Gon obtains the right to choose the artifacts from the game necessary to reunite with his father.
