Ikalgo is alone underground a mission to find Palm. Meanwhile, Knuckle has abandoned Meleron's Perfect Plan and revealed himself to Youpi. Melereon leaves Knuckle and Shoot to assist the others. However, Welfin is sharp enough to notice that Flutter, under Ikalgo's control, is behaving strangely. He also catches Melereon's scent and gives pursuit.

Shaiapouf faces off against Morel while Menthuthuyoupi is up against Shoot and Knuckle. As the various players begin their battles, the King, Netero, and Zeno also square off. Zeno uses his Nen ability Dragon Head on the King, but the King does not try to dodge. What is the King's objective? The ultimate battle between the King and Netero is about to begin.

After Gon and the Hunters infiltrate the palace, they are separated by a powerful attack from Youpi. Morel uses his Nen smoke to distract Youpi and head towards the King, leaving Shoot and Knuckle to deal with the Royal Guard. At the same time, Gon and Killua also spring into action.

Zeno and Netero's attack throws the palace into chaos. Gon, Killua, and Shoot encounter Youpi at the bottom of the stairway leading up to the King's room. Meanwhile, Pitou and Pouf rush to the King, fearing the worst. Upon arrival, Pitou begins to shed tears. What has happened to the King?

"One minute to go." Gon, Killua, Knuckle, Shoot, Melereon, and the others are waiting inside the Four-dimension Apartment. Morel tells the Hunters to prepare for the attack. Two minutes earlier, two glowing lights descended upon the Republic of East Gorteau. Neferpitou was the first to notice them. "Something's coming." A few seconds later, Neferpitou's hunch was confirmed. "The enemy!" A giant dragon drops out of the clouds. The final battle pitting human against Chimera Ant is about to begin.

The citizens of East Gorteau are assembling in front of the palace.Meanwhile, Welfin, a wolf Chimera Ant, has noticed that someone infiltrated the palace. At the same time, Secretary Bizeff has realized that Palm has disappeared and begins to search for her.

Only one day remains before the selection begins. Gon, Killua, and Ikalgo go over the operation plan one more time. They attempt to simulate every possible scenario. Meanwhile, a siren begins to blare inside Peijing.

Three days remain until the selection begins. Gon and the other Hunters are joined by new allies as they prepare to infiltrate the palace. Meanwhile, King Mereum, who has recovered from his injury, and Komugi continue to play Gungi. However, Komugi has grown fatigued.

The lion Chimera Ant Leol has chased Morel into an underground cathedral for a duel. Leol activates his Nen ability to create large waves and a surfboard. The waves are used to attack Morel while Leol rides the surfboard and charges Morel.

While the King and Komugi continue to play Gungi, Knov has successfully infiltrated the palace. His objective is to play four-dimensional exits for the other Hunters to use.

The King's meeting with world champion Gungi player Komugi has left him baffled and irritated. However, he's also enjoying their matches. The King proposes that they wager on their next match, promising Komugi that he will grant any wish she makes if she wins.

The Hunter Knov is making his way towards the Palace. The Chimera Ants Leol and Flutter are watching Knov in an attempt to learn what powers he has, but they lose sight of him.

The King is finding ways to entertain himself while waiting for the selection. He summons masters of Shogi and Go and defeats them in matches. It appears that he has incredible physical and mental strength. Next, the King summons Komugi, a blind girl who is the world champion of a board game called Gungi which originated in the Republic of East Gorteau. When the match begins, the blind girl opens her eyes.

Ikalgo betrays his fellow Chimera Ants to save Killua, his former enemy. At the same time, Gon is bonding with a Chimera Ant named Melereon. Melereon tells Gon about his own power, which is a risky move for a Nen user. However, he's willing to take that risk to build a relationship of trust with Gon, for his objective is to defeat Meruem, the Chimera Ant King.

After splitting up with Gon, Killua is attacked by an octopus Chimera Ant named Ikalgo. Ikalgo has the ability to possess humans and transform his legs into a cannon for firing projectiles. However, he's captured by Killua before he can find a host. Killua tells Ikalgo that he'll spare his life in return for information about his ally's powers, but Ikalgo tells Killua that he won't sell out.

Knuckle and Shoot attempt to ambush Cheetu, but at the last moment, Cheetu changes directions and vanishes. The two Hunters realize that someone must have warned Cheetu. Meanwhile, Killua and Gon are both being followed. The Chimera Ant following Gon decides to reveal himself.
