Gon's aunt Mito gives him the go ahead to take the Hunter Exam after he has successfully passed her test, using a special rod from his father. Gon goes to town to catch a ship to the exam. In town, Gon befriends Leorio, after several run-ins with each other through the town. Leorio is also intent on taking the exam, and they take down a cruel animal show. In the end, they almost miss the ship, but through Gon's quick thinking, they manage to board the ship at the last minute.

Hisoka determines the real examiner by flinging deadly playing cards at each man, reasoning the true Hunter will live, and it's Satotz. Later, he plays at being an examiner and kills many examinees. Although Hisoka is able to kill all of his intended victims, he recognizes that Gon and Leorio are special and lets them live.

Leorio goes next. His opponent is Leroute, an attractive woman. He loses ten hours in bet to her so that he can grope her. He then loses the rest of their betting hours to her in a game of rock, paper, scissors. Killua then faces Johness the Dissector, a serial killer responsible for the murder of at least 146 people with his bare hands. Killua rips out his heart, explaining afterwards that Johness is an amateur and he is a pro.
