S1·E49 Heart Tone × Kurapika × Dowsing

Gon and Killua order a Joystation and see that the card they have contains data for Greed Island game that cannot be found on Internet. Killua calls his brother who is a devoted gamer, but even he doesn't have that one (however, he provides some information in exchange for the data from Gon's ROM card). Back to Kurapika, they manage to identify two spies: Shachmono Tocino and Squala, who already work for the same boss and were asked to test the four rookies.
