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, 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.

Killua and Gon learn about Nen from Wing, Zushi's teacher. Nen involves using your body's aura while fighting. On their way to register for the fights on the 200th floor, they're stopped by Hisoka. He doesn't think they're ready to fight at a high level. He uses his Nen to block them, and they have 3 hours to learn enough Nen to get past him, or Killua can never fight in Heavens Arena again.
