Chapter Summaries

Key plot points and events

• Sengoku hears reports of a teenager carrying one wooden sword and one real sword—details matching the wanted Lin Mo—and sends Akainu to search Sabaody’s Groves 40–49.
• Lin Mo passes Marines searching nearby without attracting their attention and reaches the shipyard, where Rayleigh and Enel have nearly finished coating the Flying Ship.
• The shipwrights refuse Lin Mo’s payment, citing their friendship with Rayleigh and Kaku’s past apprenticeship. Lin Mo’s group departs soon afterward, leaving Rayleigh behind; the shipwrights suspect he is heading back to gamble rather than home to sleep.
• At the shore, the bubble-coated Flying Ship safely sinks beneath the sea and begins its journey toward Fish-Man Island.
• Rayleigh overhears Marines say Lin Mo’s group is heading underwater. He blocks Akainu’s pursuit, forcing the admiral to stay and fight him.
• Akainu sends his Marines ahead while battling Rayleigh. Their clash is brief but intense: Rayleigh blocks Akainu’s magma attack and cuts through his legs, though Akainu reforms them with his Logia power.
• When a Marine reports that Lin Mo’s ship has already submerged, Rayleigh vanishes, and Akainu is left too late to stop the departure.
• Underwater, Enel and Kaku’s initial fear gives way to excitement as they admire the ocean and anticipate Fish-Man Island.

Character developments and interactions

• Lin Mo remains composed despite the Marine search. He pays for the ship’s coating without fuss and lets the shipwrights’ refusal stand.
• Rayleigh protects Lin Mo’s head start while pretending not to know him. His easy banter contrasts with his willingness to confront Akainu directly.
• Akainu is frustrated by Rayleigh’s interference and prioritizes capturing Lin Mo’s group, but cannot ignore Rayleigh’s challenge.
• Enel and Kaku are wary of descending into the sea because their Devil Fruit powers make them vulnerable, but wonder quickly overcomes their anxiety.
• The shipwrights show loyalty and affection toward Rayleigh and Kaku, while joking about Rayleigh’s likely gambling habit.

Significant themes

• Loyalty and protection: Rayleigh risks confronting a powerful Marine to help the younger crew escape.
• Freedom and the journey ahead: The ship’s descent marks the group’s departure from Sabaody and a bold step toward the unknown.
• Camaraderie and humor: Friendly teasing among the shipwrights and Rayleigh lightens the tension surrounding the pursuit.
• Different kinds of strength: Akainu’s destructive power is checked by Rayleigh’s skill and experience, while restraint and timing prove as important as force.

Key plot points and events

• Lin Mo, Kaku, and Enel descend from Sabaody toward Fish-Man Island aboard their bubble-coated Flying Ship. Kaku warns that the bubble can withstand deep-sea pressure but could burst under heavy damage, so they must avoid hazards.
• The crew encounters several huge sea beasts. Enel uses the Ruyi Jingu Bang to kill them without widening it enough to endanger the ship’s bubble.
• Near a powerful, waterfall-like current, a giant tentacle attacks. Kaku leaves the ship inside a smaller protective bubble to fight it, secured by a rope held by Enel.
• The creature is Kraken. Kaku severs one tentacle with Demon Spirit, whose wound is consumed by mysterious black mist. While dodging Kraken’s counterattack, Kaku moves too quickly for his bubble, touches seawater, and loses his strength. Enel pulls him back aboard.
• Lin Mo retrieves the sinking Demon Spirit through his system ability. Enel then realizes he can control the Ruyi Jingu Bang at a distance, allowing it to grow enormous outside the ship’s bubble and knock Kraken into the current.
• Kaku apologizes for losing Demon Spirit. Lin Mo silently gives it back and warns him not to lose it again. The ship continues toward Fish-Man Island.

Character developments

• Lin Mo is unsettled by the unfamiliarity of descending underwater and briefly tests whether he is dreaming. Though reserved, he acts decisively to recover Kaku’s weapon and shows clear concern for his crew.
• Kaku remains cautious and resourceful, but his confidence in handling Kraken leads him into danger. He feels responsible for losing Demon Spirit and is relieved when Lin Mo returns it.
• Enel starts out dismissive of the dangers and repeatedly jokes with Kaku, but he takes responsibility for holding the rescue rope and proves effective in battle. He also discovers a crucial new way to use the Ruyi Jingu Bang remotely.

Character interactions

• Kaku and Enel trade teasing insults, with Kaku deliberately provoking Enel and Enel complaining that Lin Mo treats Kaku better than he does.
• Lin Mo allows Kaku to pinch his cheek to confirm that the experience is real, but threatens Enel when he tries to do the same.
• Despite their banter, Enel rescues Kaku, and Kaku later shows remorse over the lost blade. Lin Mo’s quiet act of returning it—and his warning—reinforces the crew’s trust and hierarchy.

Significant themes

• Peril and cooperation: The deep sea makes even powerful abilities dangerous; survival depends on caution and relying on one another.
• Loyalty beneath teasing: The crew’s constant bickering coexists with practical care and willingness to protect each other.
• Discovery and adaptation: Enel’s insight into the staff’s independent control turns an apparent limitation into a decisive advantage.
• Unexplained power: Demon Spirit’s black mist and Lin Mo’s ability to retrieve the blade hint at mysteries still unfolding.

Plot points and events

• Lin Mo, Enel, and Kaku descend toward Fish-Man Island aboard their flying ship. Enel pilots through a powerful underwater current, using Observation Haki to avoid rocks and sea beasts in the darkness.
• Near the seabed, they find a canyon and spot a strange, battered pirate ship carrying living beings. Kaku guesses its occupants are Fish-Men or Mermaids, and the party continues downward.
• They discover Fish-Man Island inside a vast double-layered bubble. En route to its entrance, they are blocked by Fish-Men riding giant sea beasts. Enel knocks them aside with the expanding Ruyi Jingu Bang.
• At the Circular Passage, Mermaid guards register the visitors. Kaku gives their names and explains that the group is there to see the island. Enel is disappointed that the two guards do not match his expectations of Mermaid beauty.
• The ship is carried by an internal current to a pool inside the island. Enel lands it on shore, where Lin Mo receives a system check-in reward: an unhatched pet egg.
• An elderly Mermaid insists that the ship be moved into the water. After Kaku warns him, Enel complies: the ship’s electrical barrier shocks and damages many nearby vessels. The old man panics and begs them to put the ship back on land as the three walk away.

Character developments and interactions

• Enel shows confidence in his piloting and combat, expertly navigating the descent and swiftly defeating the entrance patrol. His curiosity about Mermaids gives way to comic disappointment when the first ones he sees fail to meet his expectations.

Plot points and events

• Enel argues that the group shouldn’t have to move their ship just because an old merman asks. Kaku counters that ignoring someone who isn’t worth the trouble can be wiser than fighting, while Lin Mo stays out of the debate.
• Lin Mo asks the system about a pet egg: it must be kept in sunlight and will hatch in four to eight months, but its species and appearance are unknown. He gives the large, orange-yellow egg to Kaku to care for.

• Cathy and Camie take the group to Mermaid Bay, a colorful coral community, and then toward the Coral Apartments, where they live.
• Lin Mo walks past a group of welcoming young mermaids without engaging, while Enel and Kaku resume bickering. At Lin Mo’s call, they promptly stop and follow him.
• The group descends to the underwater apartments in a bubble carried by a sea-turtle elevator; Cathy and Camie swim alongside. Enel and Kaku argue about whether they might ever return to Sky Island. Lin Mo’s harmlessly ambiguous hand-flex frightens Enel, and Camie warns them not to damage the bubble. They arrive safely at Cathy and Camie’s building.

• Royal Army ship arrives afterward. Its commander, Prince Fukaboshi, recognizes what happened and first checks that Cathy is safe.

Character developments

• Lin Mo remains detached and practical: his willingness to help is driven largely by his hopes of progressing a system task, and he delegates the fight to Enel.

• Shyarly predicts that a new crew member will join Enel’s ship in two years. After Enel leaves, she consults her crystal ball again and sees a future beach party bringing humans and mermaids together. She spots Enel and suspects Lin Mo and Kaku are there too, along with a woman and a large creature. She concludes that this future gathering poses no danger to Fish-Man Island.
• Cathy buys coffee for the group and asks Enel to carry it to Lin Mo while she shops. Enel agrees to take the coffee but refuses to go shopping with her.

• Cathy and Camie prepare a meal, but the mostly vegetable-and-shellfish dishes are bland and disappoint Lin Mo and Enel.

• Fukaboshi gives Lin Mo Bubble Coral so the Devil Fruit users can travel safely through the palace’s seawater. Kaku asks to keep it for emergencies, and Fukaboshi agrees.

• Fukaboshi reveals that the three are wanted by the World Government, including Lin Mo, whose bounty is 1.54 billion. Neptune recognizes Lin Mo as the man who killed a Celestial Dragon, but decides to reward the group for helping his people. He announces a three-day, three-night feast and dismisses the risk of harboring wanted criminals.

• Fukaboshi treats the visitors courteously and helps them enter the palace, while honestly revealing their wanted status.
• Neptune appears gentle, childlike, and generous. Despite his adviser’s warnings, he chooses hospitality and gratitude over fear of the World Government.

• Lin Mo knows Shirahoshi has been confined in the tower for years to protect her from Vander Decken IX. Decken’s Mark-Mark Fruit lets anything he throws home in on a person he has marked. He has been targeting Shirahoshi since she was six, first with unwanted gifts and letters and later with weapons.
• Kaku opens the tower’s enormous, weapon-studded door. A spike flies toward Shirahoshi, but Enel and Kaku deflect it before it can hit her. The noise wakes Shirahoshi, who turns on the lights and meets the three visitors.
• Elsewhere, Decken wrongly interprets the spike’s unusual path as a sign that Shirahoshi is responding to his “love.” He throws a sword, which initially flies the wrong way but then turns back toward the tower.

• Neptune is hospitable and generous, promising the visitors three days at the palace and another, livelier banquet.
• Shirahoshi is introduced as a frightened, isolated princess, kept behind a fortified door because of Decken’s attacks.

• Lin Mo offers Shirahoshi a wish as compensation for frightening her. Learning she has been confined for nearly five years, he insists on taking her to the Sea Forest, which she has long wanted to visit because her mother, Queen Otohime, is buried there.
• Shirahoshi hesitates, worried that leaving will endanger her and upset her family. Lin Mo, Enel, and Kaku assure her they can protect her. She finally agrees to go, provided she can return before dinner.

• Shirahoshi is frightened and easily moved to tears, but also trusting, polite, and eager for companionship. Though anxious about danger and her family’s concern, she gradually finds the courage to pursue a long-held wish.
• Lin Mo remains reserved and goal-focused. He protects Shirahoshi, then firmly pushes her toward the Sea Forest—partly out of concern for her and partly because he expects the outing may advance a task.
• Enel is abrasive and impatient with Shirahoshi’s crying, but ultimately backs down when Lin Mo intervenes. His teasing rivalry with Kaku continues.
• Kaku acts as the practical mediator: he reassures Shirahoshi, criticizes Enel’s harshness, and emphasizes the risks of harming a princess.
• Shirahoshi quickly trusts Lin Mo after he saves her, while the crew members are puzzled by his unusually considerate offer and speculate about his motives.

Plot points and events

Neptune and his sons ask them to keep the killing secret, both to protect their own political standing and to preserve Queen Otohime’s dream of peaceful coexistence.
• Vander Decken’s followers expose the three humans in the island’s main square and demand their execution. Neptune struggles to protect his guests without appearing to side against his people.
• The crowd’s anger shifts when Madame Shyarly intervenes. She says she foresaw humans and Fish-Men sharing a bonfire beneath the same starry sky, and saw Lin Mo and his companions in the vision. Trusting her prophecies, the crowd embraces the possibility of peace and largely abandons its hostility.
• Neptune’s family treats the visitors as benefactors and invites citizens to their banquet. Lin Mo’s system then confirms that he has earned Neptune and his sons’ approval, completing the Fish-Man Island sign-in and raising his Observation Haki to level 8.
• The upgrade overwhelms Lin Mo with a sudden flood of voices. He nearly collapses, and Enel and Kaku catch him as Shirahoshi checks on him.

Plot and events

• After recovering from a brief episode of head pain, Lin Mo refuses medical attention. When Enel jokes that he was faking, Lin Mo punches him, though Enel soon returns unharmed.
• Neptune holds a three-day banquet to honor Lin Mo and his crew. Kaku and Enel enjoy the festivities, while Lin Mo keeps to himself. The crew then spends two more days coating the Flying Ship and nearly a month exploring Fish-Man Island.
• At departure, Shirahoshi tearfully asks them to stay. Lin Mo offers only a brief goodbye; Kaku reassures her that Lin Mo is simply reserved. Worried about the crew’s safety, Shirahoshi asks to follow, but Neptune refuses and sends her brothers to escort them instead.
• Lin Mo sets Zou, in the New World, as their destination, hoping to find its historical stone tablet. He expects the trip to take at least a month because of the distance, unstable weather, and Zou’s constant movement.
• During the voyage, Kaku spots a rare deep-sea fish and, with Enel’s help, catches it alive for its valuable meat and bones. The fish slows the ship and draws it toward a dangerous White Dragon Current. Lin Mo orders the crew to keep the catch, but the current suddenly curls around and swallows both fish and ship.
• Fukaboshi and his brothers arrive in time to see the ship vanish. Trusting Madame Shyarly’s prophecy that the crew will one day appear with them on land, Fukaboshi believes they will survive. The brothers decide to return and keep the incident from Shirahoshi. Inside the current, Lin Mo, Kaku, and Enel cling to whatever they can as the ship tumbles.

Character developments and interactions

• Lin Mo remains blunt and emotionally restrained, but he gives Shirahoshi a farewell when prompted by Kaku and makes the call to risk the ship rather than abandon the valuable fish.
• Kaku acts as the crew’s practical, sociable caretaker: he comforts Shirahoshi, prepares the fishing gear, and thinks ahead about supplies and money.
• Enel continues to tease Shirahoshi and argue with Kaku, but readily works with him to catch the fish. His boastfulness is tempered by the real danger of the current.
• Shirahoshi is openly affectionate and anxious about the crew, while Neptune protects her by refusing to let her follow. Her brothers share her concern and set out to escort the ship.

Significant themes

• Practicality versus appetite: Kaku’s wish to secure food and income drives the fish-catching episode, even as the catch creates danger.
• Fate and uncertainty: Fukaboshi’s faith in Shyarly’s prophecy offers hope, but the crew’s fate inside the unpredictable current remains unknown.
• Adventure and risk: The journey toward the New World begins with an abrupt reminder that even routine travel can become life-threatening.

• After Ace sails away, Luffy vows to grow stronger and carry on Sabo’s dreams as he pursues his own ambition to become Pirate King.
• Sabo reaches Foosha Village carrying white lilacs. Although Koala offers to accompany him, he goes ashore alone, apparently drawn by the island’s connection to Lin Mo and Lin Mo’s sister.

Character developments and interactions

• Lin Mo remains reserved and sleepy, but his growth is quietly noted. He also shows a threatening side when Enel repeatedly teases him.
• Kaku is practical and good-humored: he helps navigate danger, cooks lunch, cares for the egg, and takes an almost parental interest in Lin Mo’s growth.
• Enel is proud and quick to complain, but contributes decisively during the storm. He learns to hold back after Lin Mo’s Haki puts him in his place.
• Sabo appears troubled and increasingly drawn to Foosha Village, though he avoids explaining his feelings to Koala.
• Koala is attentive and supportive, sensing Sabo’s unease and offering to accompany him.

Concise chapter summary

• Sabo searches for Lin Mo’s family. After paying his respects to Lin MuMu, he asks a Foosha Village fisherman about her. The man has never heard of Lin MuMu but remembers Lin Mo, who washed ashore alone after a shipwreck at age ten. Sabo is unsettled by the claim that Lin Mo was the only person found.
• Sabo questions Makino. At her tavern, he learns Lin Mo never spoke about his family and stayed in the village only a little over two weeks. Makino recognizes Sabo’s resemblance to a boy she once knew—implicitly Ace—and tells him to pass her greetings to Lin Mo. Outside, Sabo briefly hears two familiar young voices calling his name, but sees no one.
• The crew reaches Zou. After a long, leisurely voyage delayed by the White Dragon Current, Lin Mo, Kaku, and Enel spot a huge elephant moving through thick fog. Lin Mo confirms their destination is Zou, home to the Mink Tribe.
• They enter the settlement. The flying ship bypasses Zou’s protective currents and fog, passes through its ancient gateway, and heads for the Whale Tree. A lookout monkey spots it and sounds the alarm. Mink residents call the newcomers intruders and expect the Guardians to stop them.

Character developments and interactions

• Sabo is moved by his unresolved debt to Lin MuMu and becomes suspicious that Lin Mo’s past may be more complicated than villagers remember. He decides to investigate further rather than leave immediately.
• Makino remains warm and compassionate, sharing what little she knows of Lin Mo and expressing grief for the boy Sabo resembles.
• Lin Mo stays relaxed and unhurried, even as the crew approaches an extraordinary destination. He directs the ship to the Whale Tree.

Character developments and interactions

• Pedro’s determination to defend Zou persists despite his injuries; he ignores Black Buck’s advice to rest and attacks the ship, only to be overwhelmed.
• Enel remains boastful and contemptuous, while Kaku is more measured and uses his specialized device and combat skills to counter the Guardians. Their teamwork quickly turns the fight in their favor.
• Lin Mo stays detached and practical: he neither pursues Pedro’s attackers nor offers Pedro help, and treats the surviving Guardian calmly after demonstrating his overwhelming strength.
• The chapter introduces Zou’s twin rulers: Cat Viper, the fierce King of the Night, and Inuarashi, the gentle King of the Day. Though opposites in temperament and schedule, both are loyal, honorable leaders who would risk their lives for their companions. Lin Mo expects that befriending them will be straightforward.

Significant themes

• Kaku serves as the dry, teasing voice of reason, correcting Enel’s claims and explaining Carrot’s intentions.
• Their exchanges contrast Enel’s arrogance and volatility with Carrot’s straightforward enthusiasm and Kaku’s humor.
