Chapter Summaries

A wounded Lunarian fought CP9 after Balo revealed the secret behind their plan to capture her. She killed Balo and prepared to keep fighting, believing she would not survive.

• CP9 agents blamed Balo for exposing their plan, and their leader ordered them to await reinforcements before beginning the capture operation.
• The Lunarian charged Balo and wounded him despite his Tekkai, then pressed her attack while the other agents tried to help him.
• The CP9 leader's shuriken struck the Lunarian's shoulders, but she accepted the wounds to increase her speed and stab Balo through the heart.
• The Lunarian kicked Balo into the sea, removed the shuriken, and asked the remaining CP9 agents who would be next.
• The Lunarian thought she might break her promise to her parents and admitted to herself that she was not strong enough to keep living.

Amphitrite fought off CP9 agents but was weakened by an anesthetic developed by Saint Saturn, leaving her at the commander’s mercy. Just as the commander ordered his agents to capture her, the feared Vampire Nereus appeared behind him.

• Amphitrite remembered her parents’ final plea to survive and killed Balo and two other CP9 agents while fighting to escape.
• CP9 reinforcements arrived as Amphitrite’s stamina dwindled, and the commander revealed that a shuriken had delivered Saint Saturn’s anesthetic.
• Amphitrite tried to finish the commander with Flame Phoenix: Meteor, but the drug paralyzed her body before she could strike.
• The commander ordered his agents to seize Amphitrite, but they stared in terror at something behind him.
• Nereus appeared behind the CP9 commander with a blade-like nail against his throat.

Nereus killed the CP9 agents who tried to bargain with him, then caught Amphitrite as Saturn’s drug left her unable to control her body. Amphitrite pointed weakly toward a bottle in the sea.

• The CP9 commander tried to negotiate with Nereus by offering the Lunarian’s bounty, but Nereus drained his blood and killed him.
• The remaining CP9 agents fled using Soru and Geppo, but Nereus pursued them with blood arrows and killed them in the sea.
• Nereus sank the agents’ ship after eliminating the CP9 group.
• Saturn’s drug took effect, and Amphitrite fell toward the sea before Nereus caught her.
• Amphitrite told Nereus that the bottle was in the sea.

Amphitrite told Nereus she had thrown a secret the World Government wanted hidden into the sea, and he used his ability to communicate with marine creatures to recover it. The bottle contained a Poneglyph message, which Nereus could read, leaving Amphitrite surprised that he knew the ancient script.

• Amphitrite explained that she had thrown a bottle into the sea while fleeing the CP9 agents, and Nereus decided to search for it.
• Nereus invited Amphitrite to join him against the World Government and offered her a safe place if she declined.
• Nereus called fish and dolphins to search the waters, and a pink dolphin brought him the bottle Amphitrite had discarded.
• Nereus opened the bottle and read the ancient script on the parchment, identifying it as a Poneglyph.
• Amphitrite said she did not recognize the script and had only memorized its translation, then wondered how Nereus could read it.

Nereus rescued the injured Lunarian Amphitrite and welcomed her aboard as a companion. As Nanamo wheeled Amphitrite toward the infirmary, she asked whether Amphitrite was short on money.

• Nereus invited Amphitrite to recover aboard his ship and promised not to abandon her if she joined him.
• Amphitrite accepted Nereus's offer and introduced herself as a member of the Lunarian Tribe.
• Nanamo waited anxiously for Nereus's return, while Hermes claimed Amphitrite had looked at him suspiciously and might threaten Nanamo's status.
• Nereus introduced Amphitrite to the ship's officers and asked them to arrange a room and call the doctor.
• Nanamo took Amphitrite to the infirmary in a wheelchair and asked if she was short on money.

Nanamo welcomed Amphitrite aboard and proposed a scheme to use her bounty to lure the World Government into a trap. Amphitrite agreed the idea had promise but wanted to kill her pursuers herself, and she recovered from her poisoning before the ship’s doctor could treat her.

• Amphitrite told Nanamo that she had no use for money, and Nanamo introduced herself as Nereus’s daughter and called them companions.
• Nanamo asked whether Amphitrite might become her stepmother, and Amphitrite explained that she valued a partner’s strength; Nereus met her standards.
• Nanamo proposed reporting Amphitrite’s location to the World Government for bounty money, then having Nereus defeat the agents who came to capture her.
• Amphitrite liked the plan as a chance for revenge but said she wanted to kill her enemies herself, so Nanamo suggested Nereus train her after she recovered.
• The ship’s doctor could not treat Amphitrite’s poison because her body broke down the medicine, and she recovered through her own antibodies.

Amphitrite joined Nereus's crew and began cautiously participating in their welcome banquet, while Nereus reassured her that she no longer needed to hide. After Kaido left to seek a Lunarian companion, Nereus's group returned to an island where the people welcomed him back.

• The ship doctor reported that Amphitrite was physically well but malnourished, while Hermes relayed that she would skip the banquet to research something.
• Nereus's ships crossed the Calm Belt using Sea Beasts and Seastone, and Amphitrite arrived at the crew's welcome banquet wrapped in Bandage.
• Nanamo brought Amphitrite to Nereus, who told her she could live openly among the crew; she gradually joined the celebration without removing her Bandage.
• The group reached the New World, where Kaido departed as an Azure Dragon to find a companion, saying a Lunarian might be a good choice.
• Several days later, Nereus's group approached a populated island, and its guards rang a bell and announced his return.

Nereus returned to his island refuge, then sailed toward Fish-Man Island while training Nanamo and Amphitrite in Haki. As the ship approached the Red Line, Amphitrite insisted she could swim down with Nereus and Nanamo despite the ten-thousand-meter descent.

• Nereus welcomed the people he had rescued and arranged housing for newcomers before preparing to take South Blue residents home.
• Nereus resumed Haki training at sea, and Amphitrite quickly began to grasp Armament Haki while Nanamo struggled through the lessons.
• The ship reached the Red Line, where the crew began coating it with Yarukiman Mangrove resin for the descent to Fish-Man Island.
• Nanamo asked Nereus to swim down with her, and Amphitrite said she could hold her breath for two hours and join them.
• Sebastian questioned Amphitrite's claim that she could swim to Fish-Man Island, which lay ten thousand meters beneath the sea.

Nereus led Amphitrite and the others through the deep sea to Fish-Man Island, where Amphitrite saw the island for the first time. After they entered through the national gate, a dispute broke out between Neptune Army soldiers and a merchant ship whose crew refused an inspection.

• Amphitrite followed Nereus into the water, while Babel and Big Pan stayed aboard the ship and Sebastian and Sambel acted as rear guards.
• Nereus took Amphitrite's hand and guided the group through the dark, fast-moving current toward Fish-Man Island.
• Nereus and the others reached the island, and Amphitrite admired its coral reefs, shell-shaped houses, and bubble waterways.
• Nereus explained that they would rest before visiting the Fish-Man District, but a dispute began at the checkpoint over parents' claims that a child had been brought aboard a departing merchant ship.
• The merchant ship's crew threatened to stop delivering supplies if the Neptune Army soldiers insisted on inspecting the vessel.

Nereus intervened when a merchant threatened Fish-Man Island over a search for a missing child, forcing Umit to condemn slave transport and warn his shipping supervisors. Sebastian found the unconscious Mermaid aboard the ship, and Ladis was killed after the child was returned to her parents.

• Nereus took the Den Den Mushi from Ladis and called Umit, who denied ordering threats against Fish-Man Island.
• Nereus warned Umit that others would take over sea transport if Umit would not cooperate, and Umit ordered his supervisors to ban slave transport.
• Sebastian searched the ship, found an unconscious little Mermaid in the hold, and returned her to her parents.
• Sebastian grabbed Ladis and crushed his spine after Ladis claimed the child might have boarded the ship herself.

Nereus ordered an investigation into a smuggling syndicate and criticized Fish-Man Island’s timid rulers before visiting Fish-Man District with Amphi. There, Fisher Tiger introduced himself and asked to join Nereus as an explorer.

• Nereus ordered his men to interrogate the smuggling syndicate and kill those involved in trafficking slaves.
• Nereus rebuked a Neptune Army soldier for tolerating Pirates and blamed Fish-Man Island’s royalty for its failure to protect its citizens.
• Nereus bought Bubble Coral for Amphi and took her to Fish-Man District, warning her to extinguish the flame on her back.
• Fish-Man District’s residents welcomed Nereus, and Fisher Tiger arrived as the district’s leader.
• Fisher Tiger told Nereus he dreamed of exploring the world and asked to join him.

Nereus refused to take Tiger with him on his next voyage, but accepted him into his ranks and laid out the crew’s rules. As rumors spread across Fish-Man Island, Nereus settled his plans for the island and studied a shipwreck record pointing to treasure in the South Blue.

• Nereus told Tiger to stay in the Fish-Man District until he returned, then accepted him into his ranks and explained the three iron rules.
• Nereus promised to arrange a coach for Tiger, while word of his return spread through the Fish-Man District and turned into rumors about preparing for war.
• Nanamo rejected free takoyaki from a vendor and used Hermes to force payment into his cash box.
• Nereus brought his group to Coral Hill, left Sambel and Babel on Fish-Man Island, and took Sebastian and Big Pan with him toward the South Blue.
• Nereus showed Nanamo an ancient ship’s log describing a wreck carrying precious metals that had sunk in the South Blue.

Nereus explained how the Fish-Man Pirates earned money by salvaging shipwrecks and ancient technology from the deep sea. As his crew sailed toward the South Blue, they encountered a MADS vessel and arranged to meet Wobigon and deliver goods.

• Amphitrite questioned whether three-hundred-year-old shipwrecks could still be found, and Nereus explained that deep-sea salvage was the Fish-Man Pirates’ main source of income.
• Nereus described how the Great War had shattered the ancient continent and buried its kingdoms, wealth, and technology beneath the sea.
• Amphitrite asked whether the Fish-Man Race lacked money, and Nereus explained that restoring salvaged antiques and funding major projects consumed vast sums.
• Nereus sailed with a small crew toward the South Blue and spotted a MADS ship near the Calm Belt.
• Nanamo recognized the vessel and asked about visiting Wobigon, so Nereus ordered Hermes to signal the ship and Sebastian to contact him.
• Wobigon recognized Nereus’s crew, stopped the MADS ship, and prepared to meet them.

Nereus visited the MADS research ship and learned how Wobigon’s funding had supported its scientists and their projects. Buckingham Stussy offered to help Nereus sell the treasure he had acquired at God Valley.

• Judge, Caesar Clown, and Sane argued and fought aboard the ship, wrecking laboratory equipment before Wobigon ordered them to clean up.
• Wobigon told the researchers that Nereus was a major investor, prompting them to prepare project proposals instead of repairing the damage.
• Nereus arrived and Wobigon reported progress cultivating another Sun Tree Eve and researching the Lineage Factor, as well as describing Vegapunk, Judge, Sane, and Caesar Clown.
• Buckin defended her place aboard MADS by pointing to the information and technology she contributed.
• Buckin asked Nereus to let her handle the sale of his God Valley treasure.

Buckin joined Nereus’s operation, agreeing to sell goods through her underworld connections while Wobigon tracked two Devil Fruits. Nereus then met Vegapunk and challenged his belief that freely shared energy could prevent war, leaving the doctor to consider whether he would keep researching if his work became a weapon.

• Buckin explained how she had lost contact with Whitebeard and offered to sell Nereus’s goods through her underworld connections.
• Nereus accepted Buckin’s offer and gave Wobigon information on two Devil Fruits to watch for.
• Wobigon defended Vegapunk’s abilities when Sebastian complained that the doctor was making them wait.
• Vegapunk thanked Nereus for funding MADS and asked about an ancient power-core blueprint that could supply a vessel with great energy.
• Vegapunk said he hoped freely shared energy would end resource-driven wars, but Nereus argued that greed would cause conflict even with infinite energy.
• Nereus asked Vegapunk whether he would continue his research if someone took it and turned it into a weapon.

Nereus and Vegapunk reached a temporary understanding about technology and peace before Nereus left, while Judge and the other scientists learned their patron Wobigon was tied to a nearly four-billion Bounty. As Nereus’s crew continued through the first half of the Grand Line, he discussed Nanamo’s training, then heard that their latest defeated Pirates had carried a Devil Fruit.

• Nereus and Vegapunk agreed that technology could serve Fish-Man Island’s livelihoods and peace, and Vegapunk received ancient-ruin materials and artifacts from Nereus.
• Judge, Sane, and Caesar Clown arrived to seek investment, but learned Nereus had already left; Buckin told them Wobigon had a Bounty close to four billion.
• Nereus’s group continued through the first half of the Grand Line and defeated a third group of attacking Pirates since entering Paradise.
• Nereus told Nanamo that strength was necessary for protection, and Nanamo guessed he planned to make her train harder that night.
• Nereus’s crew found a Devil Fruit among the defeated Pirates’ spoils and identified it as the Paramecia Door-Door Fruit.

Nereus and his crew sailed through the Calm Belt and into the South Blue, where a detour led them to an underwater cave and a chamber containing a Poneglyph. There he encountered Dr. Clover and a group of Ohara scholars, who wondered whether he had come to arrest them.

• Nereus took the Door-Door Fruit from Sebastian and stored it away.
• Nereus’s crew entered the Calm Belt, and a Sea King towed their ship out into the South Blue.
• The navigator spotted a course deviation, and Nereus chose a revised route that passed through crew members’ hometowns and allowed them to restock supplies.
• After dropping off crew members along the way, Nereus and his group found an underwater cave instead of the sunken-ship treasure they had sought.
• Nereus swam through the cave into a chamber where Ohara scholars were studying murals and a Poneglyph.
• Nereus recognized Dr. Clover, and the scholars grew concerned that he might be a Marine sent to arrest them.

Nereus met Clover at Ohara and learned that Clover’s Poneglyph translations might contain important errors, including a reference to the Underworld. Nereus left for Sorbet, where Shark’s Fish-Man companions finally arrived to take him home.

• Nereus showed Clover an underwater Poneglyph, and Clover corrected Nereus’s translation of its ancient writing.
• Clover explained that a phrase Nereus had written should refer to the “blade of the Underworld,” prompting Nereus to reconsider his translation methods.
• Nereus thought about the Revive-Revive Fruit and Brook, then left Ohara while its scholars continued exploring the ruins.
• Nereus sailed for Sorbet, where Kuma, Ginny, and Shark struggled to get enough food.
• While Shark fished underwater, Fish-Men arrived and told him they had come to take him home.

Shark joined Nereus’s crew as Kuma and Ginny chose to leave the Sorbet Kingdom with them. The ship set off with one more stop planned: Nereus intended to find someone to accompany Nanamo at her concerts.

• Shark reunited with the Fish-Men, accepted Nereus’s offer to join the crew, and chose a tattoo design.
• Nereus asked Kuma and Ginny whether they would leave the Sorbet Kingdom, and they agreed to go with him.
• Before departing, Kuma left the church open for anyone who needed shelter.
• Nereus told Nanamo that Kuma and Ginny could become part of her future crew and that he saw potential in Jinbe.
• Nanamo asked whether they were heading to Fish-Man Island, and Nereus said they were detouring to find someone to accompany her concerts.

Nereus brought Kuma and the others aboard, where they studied, joined Nanamo’s fan club, and witnessed Fish-Man combat on the voyage back. As the ship entered the Florian Triangle, Nereus spotted a giant ship in the fog and flew off, calling out to Harald.

• Nereus put Kuma in the shipboard classroom, where he studied alongside Ginny and Shark.
• Hermes recruited Kuma and the others into Nanamo’s fan club and gave them fan shirts.
• Kuma and Ginny watched Fish-Man fighters sink an attacking pirate ship with Fish-Man Karate.
• Nereus’s ship entered the foggy Florian Triangle after an otherwise uneventful return voyage.
• Sebastian spotted a huge shadow in the mist, and Nereus flew toward it and called out to Harald.
