Everybody in Greed Island participates in a quiz. Gon scores the highest with 87 correct out of 99 questions, wins card #00, and gets instructions to go to Greed Island Castle. There he meets 2 other game masters who give him his reward, a small binder which can be used to take three Greed Island cards out into the "real" world. With Killua and Biscuit they finish the game and leave Greed Island. Once outside Gon and Killua uses the card Accompany to fly to the player with the codename "Nigg", which Gon believes is an alias of his father, Ging. This episode ends exactly at Chapter 185, page 10-11 of the manga.
Gon, Killua and Biscuit go with the united team to find information about a card no player has been able to obtain. They find the location of the card, but fail to defeat the game master Razor and his fifteen Devils in a series of sports related one-on-one contests. Gon, Killua, and Biscuit organize a stronger team to tackle the challenges, which includes Hisoka and Tsezuguera.
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.
