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.

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

Pitou completes Komugi's treatment and Gon forces her to accompany him to Peijing in order to restore Kaito's mind, while Komugi stays behind with Killua and the others. Meanwhile, Pouf and Youpi reach the site of Netero's battle with Meruem and can't hide their feelings of sadness upon finding their king's maimed body.

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.

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.

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.

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.

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.

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.

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.
