But Chrollo is the one who has vanished...

Gon and Killua have finally made it inside the world of Greed Island, their clue to finding Ging. However, all they found was a message from Ging telling Gon to enjoy the game. Their first step is to find a city and gather information. There, they receive an invitation to join a group that's trying to clear the game.

After hearing Bisky's lecture on rock-paper-scissors, Gon decides to work on a special technique modeled off of rock-paper-scissors by using Enhancer, Emitter, and Conjurer abilities. Meanwhile, Killua leaves the game temporarily to take the HUnter Exam. While he's gone, Gon and Bisky find learn about the Bomber's most recent attack.

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.

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.

The Hunter Association has dispatched an expeditionary force to exterminate the Chimera Ants. Meanwhile, Gon and his friends are being targeted by Chimera Ants who seek to eat rare humans. They are forced into one-on-one battles with Chimera Ant captains. They easily dispatch their opponents, but Kite continues to feel uneasy. less.

After completing their training, Biscuit sends the exausted Gon and Killua to face Knuckle. Looking at the condition fo their opponents, Knuckle boasts that they could never move him an inch and bets his token on it. However His assumptions are proven wrong when Gon manages to land a powerful hit that knocks him out cold, and after awakening, Knuckle agrees that he will help them with their training until the deadline for returning the token comes. Meanwhile at the nest, Neferpitou focuses herself into reviving Kite for a second chance to fight him and Netero's team starts taking down small groups of Chimera Ants that bring the attention of the captains, while the king grows strong inside the queen's womb. As Gon and Killua spend their days training with Biscuit and sparring with Knuckle, Shoot, the second of Morel's disciples make plans about how to deal with them.

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.

As the battle with Knuckle begins, Gon is told that his Janken technique is fatally flawed - but Gon exploits this weakness, countering as his opponent tries to take advantage. Just as Gon is about to deal a finishing blow, he collapses from exhaustion. With the deadline the next day, the final showdown is looming. As Gon sleeps, Biscuit spars with Killua, after which she explains the nature of his own weakness. She issues an ultimatum - should he lose the next day's battle, he must leave Gon's side.

As the king kills the ruler of East Gorteau and takes over the country, Gon and Killua return to meet Palm, prepared to face her fury upon failing to fulfill their promise, but she decides to forgive them when Gon accepts her request to have a date with her. After learning from Morel that they found Kite, Gon takes Palm for her date, while Killua keeps trailing them in case of an enemy attack, and his fears are confirmed when Rammot appears before him.

Divided between his drive to flee and his will to protect Gon, Killua find himself in a dire situation until he realizes that he is under the effect of one Illumi's needles, easily killing Rammot after he breaks free fom it. Meanwhile, Gon's date with Palm turns to the worse when he claims that he can't stay by her side. As shoot returns to check on them, morel and Knuckle confront Cheetu, one of the Chimera Ants on the run.

Once inside East Gorteau, Gon and Killua take separate ways in preparation for the attack on the palace, but once alone, it does not take long for Gon to be attacked by Ants sent by Meleoron whose presence is concealed thanks to his Chameleon-like powers.

As Gon deals with his enemies, Killua tries his best to save the citizens of nearby villages from falling prey to the Chimera Ants' scheme until the Government, under the Royal Guards' control, declares martial law to hinder his plans. Meanwhile, Shoot and Knuckle detect Cheetu's presence and attempt to intercept him.

Leol's party is sent by the Royal Guard to stop Killua's interference and Meleoron is found out by Gon, but instead of fighting, the Chimera Ant attempts to reason with him while hiding his true intentions.

Killua confronts Ikalgo but later, saves him from getting eaten by his own subordinates. The Ortho Siblings confront Killua in their game, a 1-501 dart game where he gets continuously attacked. After feigning death, Killua beheads his opponents in a flash, but he collapses due to extreme blood loss and Ikalgo decides to repay the favor by taking him to be treated.

The king attempts to intimidate the Gungi champion but moved by her determination, he rips off his own arm as a form of apology. With Neferpitou using her powers to treat the king, the palace's defenses are lowered and Knov rushes to sneak inside it in preparations for the hunters' attack. Meanwhile, Palm prepares to infiltrate the palace as well.

Knov succeeds in his mission to breach the palace's security, but just feeling the proximity of Royal Guards' overwhelming aura is enough to drive him into despair. Palm takes advantage of the lecherous secretary Bizelf to infiltrate the palace as well and Morel is confronted by the Chimera Ant Leol, who fights using the powers of those who owe him a favor.

Even with his borrowed powers, Leol has been defeated by Morel while Killua recovers from his wounds and invites Ikalgo to join his side. Meanwhile, Palm starts her investigation when a massive and ominous aura surrounds her.

Shoot and Knuckle stay behind to fight Youpi while Morel rushes forward to face Pouf. While looking for Pitou, Killua turns back briefly to assist Ikalgo unaware that he accidentally put his friend's cover at risk.

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.

Cheetu attempts to provoke Zeno into fighting him, but Silva appears to pick up his father, killing the ant instanly in the occasion. Separated from the others, Youpi realizes that he failed to prevent the intruders from approaching the king and attempts to vent out his anger on Knuckle and Shoot, creating an overwhelming explosion, a feat that surprised even himself. Knuckle believes this could prove itself as an opportunity to make a comeback, while Youpi plans to use it to defeat them for good.

Ikalgo infiltrates the palace's lower levels to look for Palm with no success. While returning to the surface, his cover is blown and he finds himself trapped in the undergound with an enemy. Meanwhile, Youpi pretends to be angered in order to have Knuckle falsely believe there is an opening for him to attack. Youpi's plan works, but just before he could kill his opponent, Killua paralyzes the ant with a lighting bolt and steps in to fight him.

Knuckle and Morel confront Youpi with their lives on the line, but just a few moments left of neutralizing his nen with his ability, he is forced to abandon his master or give up on defeating his oponent.

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.

Killua meets Palm and learns that she was transformed into a Chimera. Refusing to let her see Gon in fear of what effects this could have on his already unstable mind, Killua is attacked by her, unaware that she is under Pouf's control.

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.

Pouf and Youpi sacrifice most of their own bodies to heal Meruem, who rises stronger than before, but with most of his memories missing. Pouf then decides to take this opportunity to dispose of Komugi in hopes that Meruem never remembers about her at all, but is attacked by the other hunters, who realize, much to their horror, that the king is still alive and is about to return to the palace.

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.

The King still struggles to retrieve his memories as he and his two remaining Royal Guards return to the palace. He eventually knocks out Meleoron and Knuckle Bine with his En, and later engages Shaiapouf and Menthuthuyoupi in a race against time. Meanwhile, only two remain, Palm and Ikalgo, and hide an unconscious Komugi underground.

A message of hostage exchange sends Welfin on the field. One moment he encounters Menthuthuyoupi, and the next, Shaiapouf finds Youpi lifeless. When he returns to the King, Meruem demands Shaiapouf's secrets. On their way, Shaiapouf unsuspectingly coughs out blood, just like how blood trickled from the King and Menthuthuyoupi.

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.

To ensure that Netero's last wish will be followed, Ging convinces the other members of the Zodiacs to procede with the election according to some rules defined by him. However, after the first round of voting, a winner is not decided and a second round begins. Meanwhile, Illumi informs Hisoka about Gon's condition and asks for his help to ensure Killua's safety as well, in a plan that somehow involves a fifth, yet unrevealed member of the Zoldyck siblings.

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.

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.

With only four candidates left, the election draws to its conclusion and has an unexpected turn when Leorio receives the support from two of the other remaining contestants, who are eager to prevent Pariston from winning. Meanwhile, Killua and Alluka finally arrive at the hospital where Gon is being treated.
