Babel rescued Una from Harding, whose Teleport-Teleport Fruit let him escape the Fish-Man pursuit. Back at Ryugu Palace, Nereus blamed Babel’s carelessness and ordered him to investigate Harding’s identity and motives.

• Harding teleported the ship away, escaping Babel, who chose to take Una and his people back rather than pursue him.
• Nereus reprimanded Babel for his carelessness and complacency and asked him to investigate Harding’s identity and motives.

After Harding escaped Fish-Man Island, Nereus learned that the racist pirate had sought slaves for the Hokkaidoer Kingdom and decided to make an example of him. Nereus ordered Fish-Man Island to lock down its waters and contacted Morgans with the story, leaving the island preparing to hunt Harding.

• Nereus contacted Morgans and told him Fish-Man Island would seal its waters until Harding's head was brought back.

Morgans agreed to broadcast Nereus’s announcement that Fish-Man Island would be closed until Harding’s head was delivered.

Nereus issued a bounty for Harding and sealed Fish-Man Island’s waters to outsiders until Harding was dealt with. As the order disrupted travel, Fish-Man Island’s forces turned back ships that tried to enter.

Nereus’s Sea Ban Order forced Pirate ships to turn back from Fish-Man Island, while Morgans used his News Coo network to track Harding. Morgans expected the bounty and Harding’s whereabouts to eventually force Pirates to act, and the order began to affect the wider Grand Line.

• Pirates surrounded by the Neptune Army and Sea Beasts abandoned their attempt to pass through Fish-Man Island and turned back.
• On the first day of the Sea Ban Order, scattered ships on both sides of Fish-Man Island turned back rather than fight.

• The surviving Pirates began searching for Harding, believing they could not pass while he remained alive.
• Perospero pleaded with Fish-Man Island's guardian to let his ship pass so he could bring fruit back for Charlotte Linlin.

After Morgans published Harding’s location alongside a massive Bounty, Harding fled attacks from the Big Mom Pirates and underground assassins. He escaped aboard a lifeboat, abandoning his crew as Piekro’s assassins attacked.

• Sane waited by a river and poisoned Harding with a rocket-launched weapon, but Harding escaped by teleporting away.
• Harding cut off his poisoned arm and made his way to Red Port, hoping to reach Mary Geoise for protection.
• CP agents confirmed Harding's identity, then cuffed him with Seastone and revealed they intended to collect the bounty on him.

Cipher Pol agents captured Harding and explained that the World Government would not protect him because his actions violated its agreement with Fish-Man Island. They planned to kill him and discussed how to exchange the money they had taken, wary of approaching Nereus.

• Harding struggled against Seastone chains as Cipher Pol agents mocked his appeals to Chief Hamani and explained that the World Government had authorized his capture.
• The agents said Harding had violated the ban on Fish-Man and Mermaid slavery, and that the Five Elders would not risk provoking Nereus to protect him.
• Cipher Pol agents revealed that Chief Hamani also wanted Harding dead because Fish-Man Island had disrupted his businesses.
• The agents discussed taking Harding somewhere secluded and splitting the money with their superiors.
• The agents decided to use Underworld middlemen to exchange the money rather than approach Nereus.

After Harding's body reached Fish-Man Island, Nereus lifted the Sea Prohibition Order, but the Underworld gathered to prevent another shutdown. The chapter ended with the Underworld agreeing to protect Fish-Men and Mermaids from harm rather than risk provoking Nereus again.

• The Sea Prohibition Order ended after an Underworld broker delivered Harding's corpse to Fish-Man Island, and frightened Pirates began entering the New World.

After the sea blockade revealed Fish-Man Island’s strength, Nereus introduced a militia system and sent Nanamo to observe its training. The lesson showed her that the island was preparing to destroy enemy ships from beneath the sea if a crisis demanded it.

• Nanamo watched Den teach militia trainees how to breach a ship’s hull at its weak points.
• Den’s lesson revealed that Fish-Man Island was preparing for unrestricted submarine warfare, with residents trained to sink ships from below.

Den taught Fish-Man Island residents how to attack ships as preparation for a possible crisis, while Nanamo encountered discarded newspapers reporting on the kingdom. On the Moby Dick, Neptune and Whitebeard learned that the Ryugu Kingdom would attend the Reverie and that the World Government had officially revoked Nereus’s Bounty by calling his past actions a misunderstanding.

• Den explained basic ship vulnerabilities and demonstrated advanced ways to damage a Navy warship, while Nanamo left the lesson early.
• Nanamo reflected on Nereus’s preparations for a possible dispersal of Fish-Man Island’s citizens, then Hermes explained why outdated newspapers had been discarded.

• A Pirate brought news that the Ryugu Kingdom would attend the upcoming Reverie, prompting Neptune to recall Fish-Man Island’s long absence from the conference.
• Whitebeard read that the World Government had revoked Nereus’s five-billion Bounty and publicly claimed his Pirate identity and the Mary Geoise attack had both been misunderstandings.

Harald returned to Mary Geoise and questioned why the newspaper credited Nereus with achievements Harald had earned while working undercover. Saturn explained the World Government’s plans and assigned Harald to escort Nereus from Fish-Man Island to the Reverie, leaving Harald bound for the island.

• Sebastian reported that Harald had arrived representing the World Government, and Nereus allowed him into the palace.
• Harald respectfully invited Nereus to the Reverie and asked to discuss something with him at the palace.

• Nereus told Harald to drop his respectful act, and Harald explained that he had accepted the World Government’s arrangement to help Elbaf atone for its past.
• Harald said the World Government had no demands beyond asking Nereus not to cause trouble, while Nereus warned that Harald might not be able to stop him if something happened.

• Nereus questioned the CP0 agent about his special mission, and the agent offered to take him to the meeting.

• Kings hostile to Nereus’s opposition to slavery encouraged Chaplin to confront him, and Chaplin raised the grievance on the seventh day before forty-eight kings.

Nereus confronted Chaplin with recorded proof of Harding’s insults and accepted Chaplin’s challenge to war. The World Government tacitly approved action against the Dole Kingdom, provided it stayed intact enough to pay its Heavenly Tribute.

• Nereus played a Tone Dial recording showing Harding insulting the Ryugu Kingdom and questioning the World Government.

• Saturn and Nusjuro summoned Nereus and acknowledged that the recording had damaged the World Government’s dignity.
• Nusjuro said the World Government would report that the Dole Kingdom rejected advice, tacitly allow Nereus to act, and require the kingdom to pay its next Heavenly Tribute.

After leaving Mary Geoise, he planned to investigate the Dole Kingdom before acting, while Nanamo gave Scarlet a Fish-Man Island Insurance Service voucher and the group headed to a concert at Sabaody.

• Saturn told Nereus that the Marines would mediate the Dole Kingdom conflict for appearances, while the Five Elders privately discussed using it to test whether Nereus was controllable.
