As news about the rogue Chimera Ants spread arround the world, six members of the Phantom Troupe appear at Meteor City to wipe out some of them which had established a colony there.

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 disguised Ikalgo reaches the lower levels of the palace to look for Palm, unaware that he is being followed. Meanwhile, Meleoron leaves Knuckle's side and proceeds further into the palace, but another Chimera Ant, Welfin, tracks his smell. Elsewhere, Gon and Killua find Pitou, who is too busy to fight them while tending to Komugi's wounds.

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.

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.

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.

The election proceeds without a winner determined yet, and Killua is cornered by Illumi, who demands him to reveal which secrets he is hiding regarding Alluka's powers. Meanwhile, Hisoka keeps murdering other hunters just to amuse himself.
