On the ship to the exam, Gon and Leorio meet Kurapika. The captain asks each for their reason to be a Hunter. Gon wants to find his father, Leorio wants to be rich, and Kurapika wants to be a force for justice.

Tonpa has placed Leorio and another examinee near hallucinogenic sap. In a dream state, he explains that he wants to be a Hunter to get money so he can become a doctor who doesn't charge for his services. Gon and Killua bond. At the end of the first stage, a man appears to accuse the examiner of being a fake.

The protagonists and others have passed the second stage, and they fly towards the next stage on a blimp. Anita, a girl who failed the earlier test, sneaks aboard to get revenge on Killua for the death of her father. The Hunters capture her, and Chairman Netero offers to free her if Gon and Killua can take a ball from him.

Majitani feigns unconsciousness in an attempt to run out the clock. Leorio and the leader of the prisoners bet on whether he's faking. Leorio holds the man above a long drop, and Majitani wakes up. He concedes the match to Kurapika, but the group loses a large chunk of their time because of the bet.

The group works together to separate the battleship/hotel from the island before the second wave of the storm hits. Leorio gets stuck on the bottom of the ocean in a diving suit and Gon helps him escape. Gon is then saved by Hisoka. Kurapika is knocked out but the steering is done by a mysterious examinee who seems to be Hisoka's ally. They separate the ship just in time, and a blimp comes to pick them up.

Gon stalks Hisoka, and observes Hisoka's friend transform into his real appearance. Then Hisoka decides to hunt other participants for two more points.

Gon, Leorio and Kurapika take a train towards Killua's home on Kukuroo Mountain. The last leg of the trip is spent on a tour bus that takes them to the Door to Hades, a giant gate that hides the path to the estate. A beast named Mike waits behind the gate, so Gon asks the security guard, Zebro to call Killua and have him open it from the inside.
