While following Satotz, a fog covers the swamp and most of the contestants are either rendered unconscious or killed by the traps and verocious beasts. Gon and Killua are separated from Leorio and Kurapika, and both parties are attacked by monsters. Leorio and Kurapika encounter Hisoka, who is surrounded by a group of candidates who feel that he's a threat they need to kill. Leorio and Kurapika are shocked to watch the magician easily take the group down. Hisoka then turns to Leorio and Kurapika next, but upon realizing that they were no match for him, Leorio and Kurapika run off in different directions to stop Hisoka from following. Leorio, however, returns, unable to run away from a fight. As expected, Leorio is beaten badly and knocked out by Hisoka. Gon, who got separated from Killua, arrives and hits Hisoka in the face with his fishing rod before he could kill Leorio. After the initial hit, Gon nearly gets strangled by Hisoka, but, after concluding that they have passed his "test" where he roleplayed as an examiner, Hisoka lets them go. He carries an unconscious Leorio off to the second venue, and it is shown that Hisoka is collaborating with an unknown candidate. Gon leaves by himself and finds Kurapika, who had returned and witnessed the entire scene, and they both head for the Phase Two site of the exam. Kurapika analyzes Hisoka's behavior, believing that the magician has his own standards of judging whether the person he meets is worthy of fighting against or killing. Gon confesses to Kurapika that he actually feels afraid of his encounter with Hisoka.
