The fight between Netero and the king comes to an end.

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.

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.

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.

Leorio's confrontation with Ging earns him the respect of his fellow Hunters and make him one of the frontrunners for the election. Meanwhile, Illumi begins an attack on Killua as part of his plan to kill Alluka, assisted by Hisoka, who has other plans for her.

Now knowing his fate, Meruem admits defeat and reveals that all he wants now is to spend his final moments playing with Komugi, convincing Palm to tell him where she is hidden. East Gorteau and the NGL gets in turmoil after the fall of the Chimera Ants and the Hunter Association start making preparations to decide who will succeed Netero as its president. Despite knowing that she will also be poisoned to death by staying close to Meruem, Komugi stays by his side until his last breath and passes away in sequence.

The Hunters assault on the royal palace begins. Gon and his friends break inside and come across Menthuthuyoupi, while Netero and Zeno strike from the sky and Neferpitou jumps up to confront them, just to be driven away when the chairman makes a small demonstration of his powers.

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.

Killua is allowed by his family to leave the Zoldick estate with his sister, but only under supervision of several butlers with orders to bring them home if he ever leaves Alluka's side or allows any of their secrets to be leaked. Meanwhile, Leorio appears and confronts Ging, asking him why he had not ever paid a visit to Gon at the hospital yet.

Gon apologizes to Ging for failing to save Kite and his father instructs him to apologize to Kite himself instead, affirming that he will wait for him to return. Meanwhile, Pariston wins the election, but renounces in favor of fellow Zodiac Cheadle and Killua seals Alluka's powers away to ensure that he can live a normal life beside him.

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.

As the Chimera Ants are reunited to unlock the power of Nen into their bodies, Neferpitou feels the presence of Kite approaching and leaves to confront him. Realizing that the enemy is too powerful for them, Kite warns Gon and Killua to flee, but Gon is taken by rage upon seeing Kite's arm being severed by Neferpitou and Killua is forced to knock him down and escape carrying him. After escaping the NGL, with Gon still uncounscious, Killua is approached by Chairman Netero who is sent there to wipe out the Chimera Ants assisted by two other Pro Hunters, Morel and Knov.

Far away from the palace, Netero prepares himself to confront the king, who much to his surprise, recognizes his value as a fighter and is not willing to kill him. Meanwhile, Pouf learns the situation from Pitou and sneaks past Gon's vigilance to rejoin Youpi as they leave the palace to search for the king.

Netero convinces the king to fight him by revealing that he will tell him his true name once defeated. The chairman then unleashes his most powerful technique that despite striking the king countless times, olny manages to scratch him.

Shaiapouf's plan to kill Komugi is thwarted when Killua faces him in a battle of words and speed. When the King arrives in the palace, Shaiapouf is resolved to get rid of the Gungi board before the King can remember anything else. Finally, Neferpitou and Gon arrive at the place of their long-awaited battle.

Meruem uses his final permissible En and enlightens his surrounding with that and approaches to Welfin who was not detected by his En earlier. Caught between the desire to live and avoidable death, Welfin finally utters the name of Komugi and the secret Shaiapouf was trying so hard to protect now is finally revealed with Meruem regaining all of his memories about Komugi.

After the fall of the king, the remaining Chimera Ants move on with their lives, each following their own path. However, Gon is still in critical condition after his battle with Neferpitou and Killua departs in search for a way to heal his body. Meanwhile, the top members of the Hunter Association, the Zodiacs, assemble to organize the election to choose the next president, following the will of Netero's last message.

Killua reunites with his sister Alluka and uses her as a leverage for them to be allowed to leave the Zoldick state, as her powers can only be used to heal Gon if she is close to him. Meanwhile, Illumi asks for Hisoka's help to stop Killua's plans, and with elections yet to reach a conclusion, the Zodiacs keep arguing about a possible way to bring it to end.

Gon is unable to hold onto Razor's throw and is sent to the outfield. He uses Back to return, but Hisoka is also injured and the situation looks grim. However, Gon has an idea for defeating Razor, but he needs Killua's help to pull it off.

Separated from the Royal Guard, the king departs from the palace with Netero to have their fight elsewhere and Gon, learning of Pitou's location, steels himself to confront it. Meanwhile, Pouf enters in a cocoon in preparation to confront Morel, and Shoot fights Youpi to the limit of his forces until Knuckle steps in to protect him.

Shaiapouf continues his plan to remove anything that could trigger Meruem's memory of Komugi as the King arrives at the palace. Killua continues to hold onto Komugi, and meets with Palm. Gon and Neferpitou arrive where Kite is, however, Gon must now face the truth.

Gon, Killua, and Hisoka team up to catch Razor's strongest throw. They're taking Razor head on. Once the ball has been secured, Gon uses all of his strength to launch it at Razor. The game of dodgeball is drawing to a close.

After defeating Genthru and collecting 99 restricted cards, Gon and his friends participate in the final event, a quiz tournament open to all players. After winning, Gon receives Ruler's Invitation.

At long last, the Queen gives birth to the King. The Chimera Ants are cowed by the menancing aura emitted by the King. Pitou, Pouf, and Youpi kneel before the King to greet him, but with that gesture, they have abandoned the Queen.

Gon's party confronts Youpi while Pouf and Pitou rush to the palace to assist the king, who is distraught with Komugi's condition as she gets herself badly injured during the attack.
