Gon and Killua begin training in Hatsu, the culmination of everything they've learned about Nen. And finally, Gon challenges Hisoka to return the favor from the Hunter Exam.

The biggest auction in the world is about to take place in York New City. The Phantom Troupe leader, Chrollo, has instructed the members to gather in the city. For what purpose? The band of murdering thieves is about to make its move.

The anticipated battle between Kurapika and Uvogin begins! Can Kurapika really withstand Uvogin's abilities, and just what are the full extent of the powers in Kurapika's chains?

Gon, Killua, Kurapika, and Leorio are finally reunited. Kurapika reveals his Nen powers to the others. However, Killua is afraid that Kurapika is now in danger because one of the Troupe members can read minds. Meanwhile, Chrollo is using the fortune telling power he stole from Neon to tell the fortunes of the Troupe members.

The condition for obtaining Patch of Shore is to chase a band of fifteen pirates out of town. Gon and crew are immediately taken to the boss, Razor, but they are quickly defeated. The plan is to recruit stronger party members and try again, so they start with the player named Chrollo.

Genthru has shown that he is much stronger than Gon. However, after Gon refuses to back down, he finally uses Little Flower to severely injure Gon.

Some of the more aggressive Chimera Ants have eaten the villains who ran the NGL underground and grown increasingly evil. When Gon looks away from their gruesome act, Kite admonishes him. Now, they must battle for their lives. Meanwhile, a Chimera Ant is on the verge of discovering Nen.

As the deadline established by Netero approaches, the chairman and his companions continue to wipe out the Chimera Ant squads one by one. While the remaining squad captains discuss how to deal with the problem, the final member of the royal guard, Menthuthuyoupi, is born. Meanwhile, Gon and Killua complete their training and challenge Knuckle for real.

After a brief fight with Cheetu, Morel and Knuckle return to check on Gon and Killua as they finally reunite with Kite, but upon seeing that he was turned into a mindless rogue by Neferpitou, Gon swears to avenge him. The Hunters then travel to East Gorteau, where the government summons all the population to meet at the capital for an undisclosed event in ten days. Knowing that it is all a plan of the Chimera Ants, Netero contacts the others and they start making plans to confront the king and the royal guard in the night preceding said event.

Face to face with Pitou, Gon can't hold back his rage and urges the chimera to fight him. Realizing that Pitou is willing to sacrifice itself to protect Komugi, Killua attempts to calm down his friend down with no success, but in the end, Gon gives one hour for Pitou to treat Komugi in exchange of accompanying him to meet Kite and help him recover his senses.

Pitou completes Komugi's treatment and Gon forces her to accompany him to Peijing in order to restore Kaito's mind, while Komugi stays behind with Killua and the others. Meanwhile, Pouf and Youpi reach the site of Netero's battle with Meruem and can't hide their feelings of sadness upon finding their king's maimed body.

After telling gon the truth about kite, Pitou tells gon that she is sorry for what she did, but it's too late for apologies.

With the elections in a stalemate, Pariston, the current vice-president proposes a new set of rules to his fellow Zodiacs in order to solve the impasse, but the others know that he actually plans to make use of this to secure a victory for himself. Meanwhile, Killua returns home and asks his father to let him see his younger sister Alluka, intending to use her mysterious and frightening power to grant wishes in order to save Gon's life.

Leorio is about to win the election, but loses all motivation to continue after a fully healed Gon appears before him, thanks to the power of Alluka, opening the way to Pariston's victory. Surrounded by his friends and the other hunters who celebrate his recovery, Gon meets his father at last.

Gon climbs to the top of the World Tree where Ging is expecting him, and the two finally have a heart to heart. In this occasion, Ging reveals his intentions to explore the world beyond the current boundaries known to mankind and Gon tells him of all his adventures, while his friends keep following their separate ways, each one of them with their own dreams and goals to pursue.
