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.

Gon becomes friends with Meleoron, who in return reveals the true extent of his powers and the reason why he wants the king dead. As the Hunters make adjustments in their preparations to storm the palace, the king entertains himself with board games until an unusual player appears before him.

Despite having mastered the rules of the board game "Gungi", the king is upset for still being unable to defeat the champion before him. Meanwhile, Morel is approached by Cheetu who uses his new abilities to trap him inside a closed space, claiming that he can't leave unless he manages to catch him in 8 hours.

As the king is yet to defeat his opponent, Cheetu tries to provoke Morel into running after him with no success, unaware that he is setting a trap for him. Meanwhile, Knov realizes the enemy's trick to detect him and comes with countermeasures against it.

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.

Gon and his friends make the final preparations for their assault on the palace. Meanwhile, the king is yet to defeat Komugi, the Gungi champion and when he decides to kill her, he ends up protecting her instead, for reasons that even he can't explain.

The time has come for Gon and his friends to infiltrate the palace and confront the Royal Guard, who are making preparations for the upcoming selection. As his concerns about Komugi increase, the king starts questioning his own existence and purpose.

The selection is at hand, but the king starts isolating himself from his servants, including the Royal Guard. Meanwhile, Gon's party is about to break into the palace.

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.

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.
