Gon and Killua decided to fight in the Heavens Arena to earn money and learn nen.
They could earn $1,000 for a victory and $1,500 if they win the tournament, but first they must fight their way to the finals.
With no skills to their name, Gon and Killua are given only one day to prepare themselves for the tournament.
Only in a matter of hours do Gon and Killua have a contest with Killua's older
sister and their friends, Matilda and Aiolia.
Gon and Killua showed a glimmer of
promise during their match, but it was never meant to be.
With the
help of
Shiloh, Gon and Killua defeated Matilda and Aiolia.
After the tournament, Killua's older
sister mentioned that she would pay them $1,000 and a vacation if they could defeat her in her next match.
Killua and Gon agreed, and Gon received a motorcycle as a prize.
Meanwhile, Captain Janus, an agent of the Doguke Empire, asks
Shiloh to travel to the world of Panorama Isle to stop Vugal the World
Worm.
Janus said that he needs
Shiloh to locate Shirogane, a new Doguke
Monster Master who is planning to sabotage his own plan.
Meanwhile,
Shiloh has been abducted by Aiolia, Matilda, and an assassin.
The Doguke Police officer found them and has been ordered to bring them to Janus.
While the trio are taken to Janus, Gon and Killua head to Panorama Isle.
At the island, Gon and Killua meet Matilda, Aiolia, the Doguke assassins, the Regent, and Janus.
While Gon and Killua try to figure out what is going on, Matilda discovers that his motorcycle is actually his walking motorized robot.
A few hours later, Matilda has tried to break free several time in Heavens Arena (HunterxHunter).
