Chapter Summaries

Key plot points and events

• Vegapunk realizes the “Pluton Blueprints” Caro recovered are actually plans for improved Dragon Ships—not the true Ancient Weapon. He suspects Xin Luo’s connection to the fleet but keeps his thoughts hidden.
• Xin Luo orders Vegapunk to memorize the plans, then kill himself and return under the protection of his Rune mark. He insists Pluton must be built, but not for Loa, whom he considers too powerful to possess it.
• Vegapunk agrees to leave for Turtle Island, privately despising the Antonio Family. He travels under close guard, unaware that a purge of Caro’s former loyalists is taking place.
• Vegapunk arrives safely and is welcomed by Loa. The scene then shifts to an Undead Legion camp in the Ice Domain, where Loa, Vegapunk, and Monkey D. Dragon meet.
• Before discussing Pluton, Loa offers a way to block Vegapunk’s Rune for several decades using an ice-encased Scale, protecting him from Xin Luo’s control.

Character developments

• Vegapunk shows both caution and growing independence: he conceals his discovery from Xin Luo, resents the Antonio Family, and eagerly accepts Loa’s help to escape the Rune’s influence.
• Xin Luo is revealed as calculating and ruthless, using the Rune to control Vegapunk and viewing Pluton chiefly as a counterweight to Loa.
• Loa welcomes Vegapunk and prioritizes freeing him from the Rune before beginning work on Pluton.
• Dragon appears to be working with Loa and Vegapunk, urging them to move quickly before Xin Luo discovers the deception.

Significant themes

• Power and balance: Pluton is treated as a weapon capable of upsetting the world’s existing balance.
• Coercion versus freedom: Xin Luo controls Vegapunk through the Rune, while Loa’s offer gives him a chance to act without that threat.
• Deception and divided loyalties: Vegapunk hides his knowledge and feelings, while the voyage and meeting conceal competing political agendas.

Character interactions

• Xin Luo pressures Vegapunk with orders and the Rune, while Vegapunk masks his fear and compliance.
• Loa greets Vegapunk warmly, then offers him a possible route out of Xin Luo’s control.
• Vegapunk expresses gratitude to both Loa and Dragon and pushes to begin work on Pluton, though Loa insists they address the Rune first.

Chapter 684 Summary

Key plot points and events

• The chapter explains Vegapunk’s past: after the World Government shut down his laboratory with Judge, it took control of his research and forced him to develop weapons such as the Pacifista. His childhood plans show that he wanted to use science to improve people’s lives, not serve as a weapon-maker.
• In an attempt to regain his freedom, Vegapunk investigated the Ancient Weapon Poseidon. Instead, the World Government tightened its control over him.
• Loa explains that Ivy’s power comes largely from bloodline Rune Magic, rather than Dragon Slayer Magic. The runes protect Great Dragons’ secrets by enslaving anyone without the proper blood who tries to break them.
• Loa has now grown powerful enough to use more advanced Rune Magic. He uses energy from a scale associated with Poseidon to remove the Black Rune enslaving Vegapunk.
• The chapter reveals how Dragon arranged Vegapunk’s escape. A long-term informant in the Antonio Family sent a warning before being killed by the Black-Robed Elder. Vegapunk also used small Calm-Calm Fruit Transfer devices to evade his Observation Haki-wielding watchers.
• Dragon’s plan relied on a Clone-Clone Fruit user taking Vegapunk’s place. The narration notes that Bon Clay’s death in Alabasta helped make the fruit available for this plan.
• Loa warns Vegapunk that removing the Rune will hurt. The pain is so intense that Vegapunk passes out, despite Loa describing it as “just a burn.”

Character developments

• Vegapunk is shown as a gifted scientist whose original ideals clashed with the World Government’s demands. His escape is a chance at freedom, but he remains vulnerable during the Rune’s removal.
• Loa reveals greater mastery of Ivy’s inherited Rune Magic and acts decisively to free Vegapunk.
• Dragon is shown to have planned the rescue over many years, accepting the loss of an informant and the risks to others.
• Ivy is characterized through her Rune Magic as protective of her secrets—and exceptionally ruthless toward intruders.

Character interactions

• Vegapunk eagerly examines the scale, while Dragon recognizes the devices Vegapunk used and recalls warning him about the watchers’ Observation Haki.
• Dragon and Vegapunk’s exchange establishes their history and the covert network behind the rescue.
• Loa reassures Vegapunk before applying the scale to his wrist, but his joking description of the pain frustrates Vegapunk, who ultimately collapses.

Significant themes

• Freedom and control: Vegapunk’s experience shows how scientific talent can be exploited and personal liberty stripped away.
• The cost of rescue: Dragon’s plan depends on sacrifice, secrecy, and danger to multiple people.
• Inherited power and protection: Ivy’s bloodline magic preserves Great Dragon knowledge but does so through cruel coercion.
• Pain and humor: The chapter contrasts a serious liberation ritual with Loa’s understated, teasing description of the agony.

Plot points and events

• Using a Dragon Scale Ivy left behind—whose power matched the Rune’s bloodline and soul—Loa enters Vegapunk’s Rune to try to free him.
• Inside, the Scale’s blue light protects Loa from the Rune’s black mist. He reaches the Third Seal, where Vegapunk’s soul is imprisoned in ice. Loa cannot break the seal directly, so he targets the Rune’s control over the Antonio family instead.
• Ivy’s Magic Power repeatedly tries to force Loa out. On his second attempt, he withstands it and directs the blue energy into the black Rune above Vegapunk, severing its connection.
• Loa is violently expelled from the Rune and spits blood, but the Rune burns away its black smoke and is redrawn in blue. Loa declares the work done.
• While Loa is occupied, Dragon protects him and Vegapunk with a powerful wind barrier.

Character developments and interactions

• Loa shows resourcefulness: unable to break the ice prison, he identifies a different way to restore Vegapunk’s freedom. He also endures Ivy’s overwhelming power long enough to complete the task, though it injures him.
• Dragon asks whether the process worked, then follows Loa’s request to guard him. He displays greater mastery of his Hurricane-Hurricane Fruit and remains vigilant throughout.
• Vegapunk remains unconscious and trapped in the Rune’s ice-bound inner space, suffering as the Rune is dismantled.
• Loa and Dragon cooperate through trust: Loa concentrates on the dangerous inner work while Dragon shields him from outside interference.

Significant themes

• Ingenuity over brute force: Loa succeeds not by breaking the Third Seal, but by cutting off the Rune’s control.
• Inheritance and shared power: Ivy’s Dragon Scale and Magic Power make Loa’s intervention possible.
• Trust and protection: Dragon’s role is to safeguard Loa while he works.
• Freedom from control: The Rune’s destruction of its black markings represents Vegapunk’s release from the Antonio family’s authority.

Plot points

• Loa uses the Dragon Scales’ magic to cover Ivy’s Rune seal on Vegapunk with a temporary substitute, freeing him from its control for at least twenty years. Loa expects to remove the original magic permanently before then.
• Dragon joins Loa and learns Vegapunk is free. They discuss their next move: Xin Luo may soon discover something is wrong, so Dragon must prepare the Anti-World Government Alliance to contain any conflict.
• Loa’s double takes Vegapunk and a companion to a hidden vault containing Pluton. When Vegapunk’s guard refuses to leave, Loa opens the vault anyway, triggering a deadly plague trap. The guard collapses, and Loa leads the protected Vegapunk inside.
• Xin Luo hears the guard’s transmission end but assumes Vegapunk remains bound by the Rune. Unaware that Loa and Dragon have broken with him, he plans to obtain Pluton’s blueprints and use a new Rune to control the victor of the coming Poseidon conflict.

Character developments and interactions

• Loa demonstrates both technical ingenuity and ruthless pragmatism: he saves Vegapunk, but is willing to let the guard suffer—and possibly die—to keep the vault’s secrets.
• Dragon shifts into a strategic leadership role, preparing the Alliance to respond if the partnership with Xin Luo collapses.
• Xin Luo remains confident but badly misinformed. He believes he still controls Vegapunk and misunderstands both the alliance’s breakup and the events surrounding Poseidon.
• Loa and Dragon share a brief moment of humor over Vegapunk’s ordeal, then coordinate their plans. The guard’s loyalty to Vegapunk puts him in direct conflict with Loa, while Xin Luo’s one-sided confidence contrasts with Loa and Dragon’s secret preparations.

Significant themes

• Control and deception: Loa’s false Rune conceals Vegapunk’s freedom, while Xin Luo’s belief that he still holds power leaves him vulnerable.
• Shifting alliances and mistrust: The three-way partnership has ended, with each side preparing to pursue its own interests.
• Power and contingency: The characters treat Ancient Weapons and political forces as safeguards in an uncertain struggle, while Loa and Dragon plan for conflict before it begins.

Key plot points

• Loa, Crocodile, and Carol return to the Castle through a hidden escape route after the fake Vegapunk impersonation succeeds.
• Carol, an old ally of Dragon, has been using the Clone-Clone Fruit to pose as Vegapunk. The disguise could be exposed by someone with sufficiently powerful Observation Haki, but the group’s precautions have so far kept him safe.
• Carol must escape before Loa realizes the real Vegapunk has not returned. The plan is for him to board one of three Dragon Ships during the Undead Legion’s routine patrol, making it look as if Vegapunk has fled.
• The escape is meant to buy time: Loa hopes the real Vegapunk can copy the Pluton blueprints and die as planned. If Xin Luo discovers the deception, he might release Poseidon, with catastrophic consequences.
• Carol has no safe reception waiting. The Anti-World Government Alliance has grown, but may be infiltrated by World Government spies, so he must flee without relying on its members.

Character developments and interactions

• Carol shows remarkable courage, accepting mortal danger to help avert a possible global disaster. Loa openly admires him and other selfless members of the former [Censored] Army.
• Loa is frustrated by having to operate secretly, since he could otherwise rescue Vegapunk by force. Still, he prioritizes preventing a catastrophe and personally arranges Carol’s escape.
• Crocodile efficiently carries out Loa’s instructions, reflecting the Undead Legion’s transformation into a disciplined force.
• Robin recalls her years in hiding, moving among dangerous groups and constantly pretending to be what others wanted. She wonders whether the [Censored] Army might once have helped her, though she never managed to reach them.
• Loa comforts Robin by promising she no longer has to face that life alone. She trusts his strength and calls him the strongest “Ice Dragon.”

Significant themes

• Sacrifice and moral courage: Carol risks his life for the chance to protect the world.
• Trust amid infiltration: The Alliance’s growth has weakened its security, while the World Government’s ability to plant spies makes cooperation dangerous.
• Secrecy and survival: Disguises, hidden routes, and carefully planned deception shape the characters’ efforts to avert disaster.
• Safety and belonging: Robin’s recollections contrast her isolated, guarded past with the security she now finds with Loa.

Plot points and events

• Caro quietly departs Turtle Island with the patrol as a clash erupts between Charlotte Linlin and Shanks.
• Loa has invited the powerful figures of the New World to join his cause. Teach cannot respond: his crew has dwindled, and he is occupied with the aftermath of internal defections. Kaido has withdrawn to his territory and lost much of his following.
• Linlin and Shanks are the remaining Yonko whose positions are unclear. Linlin has joined Loa’s side after regaining control of herself, though she still grieves the children Loa killed.
• Shanks refuses Loa’s path. He respects Loa’s actions but cannot accept the destruction of the dream of finding the One Piece, and hopes to revive people’s hopes.
• Linlin opposes Shanks, fearing his plan could plunge the world back into violent competition and disrupt the peaceful life she now values. She attacks with Elbaph Spear: Ikoku Sovereignty; Shanks takes the blow head-on and rushes back at her.
• Since Carmel’s death caused Linlin’s Homies to vanish, she has lost Napoleon and now fights with a specially made greatsword. She and Shanks clash with Haki, splitting the clouds, then separate and continue arguing over dreams and the One Piece.
• Linlin insists she is fighting not for Loa, but because she wants to beat Shanks. Shanks welcomes the fight as an outlet for his own frustration and launches a powerful sword attack.

Character developments and interactions

• Shanks reveals his loyalty to Roger’s legacy and his refusal to surrender hope, even though he recognizes the stakes and may be uncertain what to do if dreams disappear.
• Linlin shows that she can set aside her resentment toward Loa for what she sees as more important, while making clear that her present fight with Shanks is personal.
• Their exchange is both ideological and physical: Linlin sees Shanks’s hope as a threat to stability, while he sees abandoning the One Piece dream as surrendering the era itself.
• Teach and Kaido are shown as weakened or withdrawn, leaving Linlin and Shanks as the last major Yonko yet to choose a side.

The supplied chapter contains only a placeholder message: it says the text is being typed and asks readers to wait and refresh. No plot events, characters, interactions, or themes are available to summarize.

Plot points and events

• Three days after learning Charlotte Linlin would join the coming conflict, Loa reflects on Shanks’s determination to preserve pirates’ dignity—and on the danger of losing faith in oneself. Loa believes the hoped-for miracle will not come; he intends to reveal the truth rather than let people cling to dreams.
• Caesar reports that his new weapon, Death Realm, has run into trouble. He abandoned poison gas for a bomb based on explosive gas, but his experiments destroyed the research base and consumed the entire billion-Beli budget in under three months.
• Loa chastises Caesar and considers redirecting his work, but first asks about Enel’s Golden Maxim. Caesar says Enel and Simon are preparing to leave for the Infinite Continent. Simon’s interest in its ruins—and Robin’s recent packing—makes Loa suspect she wants to join the expedition. He privately resolves to spend more time with her.
• Loa offers Caesar a new job in exchange for research funding. The next day, Enel discovers that the gold intended for the Golden Maxim has been stolen and erupts in grief and anger. Simon responds with a baffling “Meow, meow, meow?”

Character developments and interactions

• Loa remains confident and pragmatic, balancing his plans for the larger conflict with the practical problem of funding Caesar’s dangerous research. He also recognizes that he has neglected Robin.
• Caesar is still an ambitious, reckless weapons researcher. Despite his costly failure, he eagerly accepts Loa’s new assignment when funding is offered.
• Enel is devastated by the theft of the gold needed to complete his ark.
• Simon plans to travel with Enel, ostensibly drawn by the ruins, while his oddly timed response to Enel’s outburst leaves the situation mysterious.
• Loa and Caesar’s exchange shifts from scolding to a discreet deal; the ensuing theft appears connected to the job Loa gave him.

Significant themes

• The chapter contrasts self-belief with doubt, portraying loss of faith as more frightening than rejection.
• It questions idealized dreams and pirate pride, as Loa prepares to confront people with an uncomfortable truth.
• Scientific ambition and its costs appear through Caesar’s reckless experimentation and enormous financial losses.
• The closing theft introduces deception and comic mischief, turning a research-funding problem into a sudden crisis for Enel.

Plot points and events

• Someone steals about two tons of gold from Enel’s Ark Maxim, cutting it away in oddly precise patches. Most seriously, one of the ship’s eight power-conducting gold spheres is missing, making the vessel unsafe and unable to fly to Endless Vearth.
• Robin, Simon, and Enel investigate who could have carried out the theft despite Enel’s powerful Observation Haki and the Ark Maxim’s security. Robin initially suspects Loa, reasoning that his Ice Dragon Magic might conceal his presence.
• Loa points out that the amount of missing gold should have been detectable by Enel’s Mantra, which functions like radar when combined with his Devil Fruit. Enel confirms the deduction but admits he did not notice the theft until he woke the next day.
• Simon concludes that Enel must have been drugged or otherwise put to sleep. With Enel’s surveillance bypassed, the culprit and motive are unclear, so Simon takes Enel to investigate the port for clues.
• Left alone with Loa, Robin sees through his apparent innocence and asks what he is really planning. Loa says he cannot leave yet because Xin Luo may soon notice something is wrong, but promises to go with Robin later.
• Robin realizes Loa is concealing information about her proposed trip beyond the sky. When pressed, he admits that it is dangerous: space contains threats far greater than those in the Grand Line.

Character developments and interactions

• Robin demonstrates sharp investigative instincts and her characteristic ability to read Loa. She is determined to pursue her studies, but recognizes that Loa’s reluctance to explain himself comes from concern for her safety.
• Loa is shown balancing his plans with worry for Robin. He acknowledges the danger beyond the Firmament and doubts that Enel alone could protect her there.
• Enel is shaken by the discovery that he was apparently drugged, and his prized ship’s damage leaves his dream of reaching Endless Vearth in jeopardy.
• Simon takes a practical approach, directing the investigation toward the port in hopes of tracking the stolen gold.
• Robin and Loa’s exchange is intimate and teasing: Robin even uses her powers to turn his face toward her when he tries to avoid the question.

Significant themes

• Appearance versus evidence: Loa is an obvious suspect, but the details of the theft complicate the accusation and leave the investigation unresolved.
• Trust and perception: Robin relies on her deep understanding of Loa, while still demanding honesty from him.
• The limits of known power: The Grand Line may seem dangerous, but the wider universe holds threats that make it appear comparatively weak.
• Protectiveness versus independence: Loa wants to shield Robin from danger, while Robin is committed to pursuing knowledge and making her own choices.

Key plot points and events

• Robin questions whether leaving is dangerous. Loa persuades her to wait, promising to go with her.
• Robin asks about the stolen gold. Loa explains that Enel’s additions to the Ark Maxim have made it dangerously heavy: Enel refined the gold to extreme purity, leaving it too soft to support the ship’s weight. If it launched, the structure could break apart.
• Loa admits the gold was taken to reduce the ship’s weight—but Robin suspects he is also using the theft to delay their departure, buy time to handle the Xin Luo situation, and fund an underfunded department.
• Robin ultimately guesses the real secret: Loa is hiding personal spending money from her. His scheme is threatened by the fact that Enel can keep building the ship and provide more opportunities to take gold.
• Caesar arrives, bruised and bandaged, with a message from Supreme Commander Crocodile: there is activity at Mary Geoise.

Character developments and interactions

• Robin shows concern for Loa and agrees to delay their departure. She uses her knowledge of gold’s softness to understand the danger to the Ark Maxim, then sharply reads Loa’s motives and catches his attempt to hide money.
• Loa tries to appear responsible, insisting the stolen gold was needed to make the ship safe. He is also short of personal funds because Turtle Island has little income and strict spending rules, and he quietly schemes to get around that.
• Enel is absent from the conversation but drives the conflict: his unauthorized modifications and ultra-pure gold threaten the Ark Maxim’s structural integrity.
• Caesar brings the report that shifts the scene from domestic comedy to a larger impending crisis.
• The exchanges between Loa and Robin mix affection, teasing, suspicion, and a clear imbalance: Loa has power, but Robin’s insight leaves him flustered.

Significant themes

• Appearance versus practical reality: The Ark Maxim’s dazzling gold finish conceals a serious engineering flaw.
• Trust and honesty in relationships: Loa’s protective explanations give way to Robin’s discovery that he has another, more personal motive.
• Scarcity and responsibility: Turtle Island’s lack of revenue and strict budgeting force Loa to scheme for money.
• Comedy before danger: The chapter’s playful marital argument ends with news that trouble is approaching Mary Geoise.

Key plot points and events

• Enel’s gold has already been sold by Caesar to the Black Market. The buyers offered a relatively fair price out of respect for Loa, but it still wasn’t enough to replace the gold. Caesar spent nearly all the proceeds on advanced laboratory equipment and materials before Enel could reach him, leaving Enel furious.
• Loa leaves Caesar and turns his attention to Turtle Island, where construction of Pluton continues. He has sent Crocodile to support Dragon in protecting the project and watching Mary Geoise.
• Xin Luo arrives at Turtle Island with a fleet of steel warships. He says he has come to make his position clear, not to challenge Loa. The island’s cannons and disciplined Undead Legion impress him; he realizes its wartime strength rivals that of major powers, even without relying on Loa alone.
• Xin Luo asks whether Vegapunk is still on the island. Loa claims he is searching for him too, then explains that Vegapunk said Pluton’s power source required equipment and materials from a secret warehouse beneath his old laboratory in Future Country. Loa sent people with him, but Vegapunk disappeared.
• Xin Luo reveals that the Rune mark meant to control Vegapunk failed: an attempted forced death did not return his soul, and a second attempt produced only a fragment of Soul Energy. Xin Luo suspects Loa may have freed Vegapunk, but also considers that Vegapunk might have found a way to break the mark himself.

Character developments and interactions

• Loa remains composed and gives Xin Luo a carefully prepared account of Vegapunk’s disappearance, while avoiding any admission of involvement.
• Xin Luo is increasingly suspicious but cautious. He recognizes Turtle Island’s military power and keeps his suspicions private to preserve the outward alliance with Loa.
• Caesar is injured and resentful after the gold sale, while Enel is enraged that the gold is gone.
• Loa and Xin Luo’s conversation is polite on the surface, but Xin Luo’s questioning and private doubts reveal the strain beneath their alliance.

Significant themes

• Power and deterrence: Turtle Island’s strength rests not only on Loa but on years of development and disciplined forces.
• Control and independence: Vegapunk’s apparent escape exposes the limits of Xin Luo’s Rune-based control.
• Secrecy and mistrust: Loa’s explanation leaves room for doubt, and Xin Luo must weigh whether Vegapunk or Loa is hiding the truth.
• The cost of ambition: The pursuit of Pluton’s construction drives risky decisions and puts powerful allies at odds.

Key plot points and events

• Xin Luo urges Loa to use the Undead Legion to find Vegapunk before the World Government issues a warrant, framing the search as essential to preserving world peace and balancing Poseidon with Pluton. He offers payment, but Loa refuses, claiming it is his duty.
• Xin Luo suspects Loa may be hiding something, but secures the Legion’s cooperation. He leaves for Mary Geoise, where political tensions remain unsettled after the purge within the Antonio Family.
• Loa contacts Dragon and warns him to watch for suspicious behavior within the Anti-World Government Alliance. Dragon agrees to handle any trouble himself.
• Dragon oversees a secret underground shipyard in the Ice Domain, where the Ancient Weapon Pluton is under construction. Vegapunk has divided the work: Dragon manages the hull, while Crocodile oversees security and the internal machinery.
• Dragon estimates the hull will be finished in about half a month, using Vegapunk’s smelting methods and precision tools from Turtle Island. Crocodile cautions him not to rush or compromise quality.
• The chapter ends when Vegapunk summons Dragon and Crocodile.

Character developments and interactions

• Xin Luo is cautious and strategic: he tests Loa’s sincerity, then secures a way to involve the Undead Legion without directly accusing him.
• Loa presents himself as selfless and loyal to world peace, though Xin Luo privately doubts his motives.
• Dragon is committed to completing Pluton but wary of anything that could jeopardize the project. His alliance with Crocodile remains practical rather than trusting.
• Crocodile acts as both security chief and a check on Dragon. Seeing Pluton take shape, the weapon he once pursued, he remains composed but visibly attentive to its progress.
• Vegapunk’s division of labor helps manage tensions between the partners, showing his skill not only as a scientist but also as a mediator.

Significant themes

• Power and balance: With Poseidon already uncontrolled, Pluton is presented as a potential counterweight in a looming conflict.
• Trust and suspicion: Xin Luo doubts Loa, while Dragon and Crocodile cooperate cautiously and monitor one another.
• The cost of weaponry: The Undead Legion’s strength comes at the expense of ordinary human feeling, and Pluton’s construction promises to bring immense destruction.
• Political instability: The Mary Geoise purge and the fragile alliance suggest that the danger comes not only from weapons, but also from divisions within the factions wielding them.

Key plot points and events

• Vegapunk reveals a major discovery about the construction of Pluton. After working from Loa’s ship-design proposal and studying the blueprints, he concludes that the Ancient Weapon was built in separate sections.
• The shipwrights of Water 7 built Pluton’s main hull, while another group created its propulsion, defenses, and devastating weaponry.
• Loa connects the Pluton designs to inventions already close to him: Ratchet’s Dragon Roar Cannon resembles Pluton’s weapon, and Turtle Island’s defensive and escape mechanisms resemble Pluton’s systems. He concludes Ratchet and Ulysses’s ancestors were likely among the builders.
• Crocodile adds that Enel’s Ark Maxim may have been designed around Pluton’s power source. Dragon knows about the possible ancestral connections, but not about the Maxim’s power source.
• Loa realizes he already has several key components for a Pluton-like vessel: the cannon, the Ark Maxim’s Electric Current Engine, and Turtle Island’s separation system. A hull and armor technology remain missing.
• Rather than simply celebrate the discovery, Loa begins considering what it means for the world’s balance of power.

Character developments

• Vegapunk is intensely focused and eager to share his discovery, though Loa and Crocodile’s blunt indifference briefly deflate him. Military Rations Pills help him work, but their delayed sedative effect forces him to sleep after three.
• Loa moves from shock to a broader understanding of Pluton’s design and his own resources. His final, unsettling smile suggests he may act on the discovery in a major way.
• Crocodile demonstrates caution and strategic awareness, especially when handling the Calm-Calm Fruit and revealing what Dragon does not know.
• Ratchet and Ulysses are linked to Pluton’s legacy through their ancestors and the practical engineering traditions reflected in their work.

Significant themes

• Inherited knowledge and legacy: Ancient engineering knowledge may have survived through the descendants of Pluton’s builders.
• Chance and fate: Loa’s casual shipbuilding suggestion and existing projects unexpectedly align with Pluton’s original design.
• Power and restraint: Reconstructing Pluton could upset the balance between nations, making the discovery politically dangerous.
• Innovation built from existing parts: Pluton’s power comes from combining specialized systems, a principle reflected in Loa’s own ship designs.

Character interactions

• Vegapunk seeks recognition from Loa and Crocodile, but both initially refuse to guess what he has found.
• Crocodile reports his findings to Loa over a Den Den Mushi, and the two piece together how the cannon, engines, and escape systems relate to Pluton.
• Loa’s final reaction hints at plans that could concern those around him—especially Ivy, who would recognize his expression as a sign that he is about to set something significant in motion.

Plot points and events

• Vegapunk’s defection becomes public, shocking the world, which had assumed he was a willing ally of the World Government.
• Caesar, still eager for research funding, tries to approach Loa again, but Loa denies responsibility for the earlier operation and makes clear he may abandon Caesar to Enel. Caesar stays because his experiment involving Ulysses and the Vampire Fruit is nearing completion.
• Ulysses successfully fuses with the Vampire Fruit while sealed in a Seastone coffin. He emerges younger-looking and gains a powerful illusion ability, which he demonstrates to the group.
• Loa reveals that Mihawk recently challenged him after surpassing his limits; Loa defeated him so decisively that Mihawk’s sword nearly broke.
• Loa discovers that Ulysses disposed of the traitor Ratchet’s body by feeding it to a sea beast. Since Ratchet’s ancestry was connected to Pluton, his remains might have helped reproduce its Dragon Roar Cannon. Ulysses and Caesar can only construct a weaker replica from existing plans, so they will build an empty shell in secret and wait for Vegapunk to improve it.
• Loa’s broader plan is to distribute scaled-down Pluton-derived weapons around the world. He hopes mutual fear of retaliation will deter wars—a balance of power he calls “nuclear peace.”

Character developments and interactions

• Loa remains confident and calculating, but his peaceful ambition is built on a dangerous deterrence strategy. He tests Ulysses’s new powers and keeps him firmly in his place.
• Ulysses gains a major power boost and takes pride in demonstrating it, while remaining obedient to Loa. His ruthless past is reinforced by his casual destruction of Ratchet’s corpse.
• Caesar remains self-interested and opportunistic, but his work produces a successful result. He must now cooperate with Ulysses on the cannon project.
• Mihawk has grown stronger but learns that he is still far below Loa’s level; he leaves after their brief confrontation.
• Loa and Ulysses discuss the risks of losing Ratchet’s body, then agree to keep the cannon work concealed until Vegapunk can help.

Significant themes

• Deterrence versus peace: Loa believes distributing powerful weapons can prevent conflict through fear, though the plan risks escalating the very danger it seeks to contain.
• Power and limits: Ulysses’s transformation and Mihawk’s defeat show that breaking personal limits does not necessarily make someone a match for Loa.
• Science and its consequences: The Devil Fruit experiment succeeds, while the attempt to reproduce Pluton’s weapon highlights both the promise and peril of advanced technology.

Plot points and events

• After Loa’s interference ends, construction of Enel’s Ark Maxim resumes. Ulysses rejects Enel’s ornate gold statue and decorations, forcing him to choose between the statue and a gold-plated wooden hull. Enel chooses a ship stripped of his personal flourishes.
• The Ark’s four-person crew is set: Enel, Simon, Robin, and Weber. Ulysses stays behind to lead Turtle Island; other residents have duties, and Laki and Aisa are away. Loa cannot sail because he gets motion sickness, so he flies off on his own.
• Enel delays departure with a lengthy speech until Simon and Robin make him stop. The Ark Maxim rises using its electricity-powered machinery, propellers, and Exhaust Dials, becoming the world’s first ship to fly without a Devil Fruit power. Enel sets course for Endless Vearth—the moon.
• After Loa leaves, groups across the seas feel safer shifting black-market goods. The Marines also begin selling accumulated seized property: Aokiji orders the Admirals to distribute and sell it, persuading Fujitora with written permission to gamble aboard his flagship.

Character developments and interactions

• Enel remains vain and grandiose, eager to proclaim himself a god, but Loa’s greater strength restrains him. He is thrilled by the voyage and unaware of the secret betting scheme and Robin’s hidden money.
• Simon acts as guard and adviser, keeping Enel on schedule; Robin is excited by the lunar ruins but shares Simon’s impatience with Enel’s vanity and speeches.
• Weber joins because, like Enel, he is descended from the Moon People. Ulysses reluctantly remains behind to protect and lead Turtle Island.
• Loa’s departure changes how others behave, even though he would not have cared about the illicit trade. His associates quietly profit from bets on whether the Ark can fly, keeping the scheme from Enel and Robin.

Significant themes

• Power and fear: Loa’s reputation shapes the actions of both criminals and institutions even in his absence.
• Ambition and exploration: Enel’s voyage toward the moon launches a new adventure.
• Technology and spectacle: The Ark’s flight is a historic achievement that astonishes witnesses.
• Vanity and comic irony: Enel’s self-importance is repeatedly undercut, while others exploit the occasion for profit.

• Journey to the moon: Loa, Robin, Enel, and Simon travel upward aboard the golden Ark Maxim, using oxygen masks as the air grows dangerously thin. Loa initially worries Robin may struggle, only to discover she and the others are equipped—and that Robin deliberately left him without a mask as a prank.
• A glimpse of Sky Island life: They pass Seben, an island made of cloud. Simon is awestruck by the winged inhabitants, while Enel treats the sight as ordinary. Simon needles Enel about his earlier amazement at seeing soil, provoking him into a near-fight. Simon forestalls it by putting on Seastone armor, and Enel backs down when Wyper appears.
• Space and weightlessness: The group sails on through the silent, star-filled upper atmosphere, struck by the view of the world below. As the ship nears the moon, Loa warns them to secure themselves. They enter a weightless region, where Wyper cannot move effectively and Robin uses her Flower-Flower Fruit ability to steer the ship.
• Impact and discovery: Loa has the Ark Maxim approach him, then tells Robin to accelerate it at full power. The ship carries him into the moon, where he crashes and rolls across the surface. Once his strength returns, he identifies the barrier between the moon and their world as the Illusion Crystal Wall and reacts with awe at its power.
  Character developments and interactions: Robin’s confidence and practical skill are clear: she jokes with Loa, anticipates the oxygen problem, and takes charge of steering in weightlessness. Loa shifts from teasingly competitive to cautious as the journey grows dangerous, then serves as the group’s guide through the final approach. Simon and Enel’s rivalry remains playful but prickly, with Wyper’s presence helping defuse the tension. The four share a moment of wonder at the view of space.
  Significant themes: Exploration and the vastness of the world; the contrast between familiar places and extraordinary frontiers; teamwork and adapting to unfamiliar conditions; and the mysterious power of the Illusion Crystal Wall.

Key plot points and events

• After forcing his way through a partition of the Illusion Realm, Loa was left exhausted and stuck in dragon form. The crossing stripped away his momentum and exposed him to the Realm’s deadly defenses, but his near-indestructible Dragon Body let him survive.
• The Golden Maxim crashes onto the moon. Loa confirms their destination and removes Robin’s oxygen mask: in this version of the One Piece moon, the air and gravity match those of the planet below.
• Robin is eager to explore, but Loa insists they first gather food and water. After the others climb out of the wreckage, Enel senses other people nearby.
• Loa warns Robin that someone may be taking the ruins. The group sets off, though Enel races ahead in anger, believing the moon to be his territory.
• They find the Space Pirates excavating ancient ruins and preparing to transport artifacts. Enel transforms into a giant of lightning and unleashes his 200 Million Volt Amaru attack.

Character developments and interactions

• Loa is revealed to have survived the Realm’s lethal rejection through endurance rather than choice. He remains protective of Robin, rescuing her after the crash and prioritizing supplies before exploration.
• Robin is curious and adventurous, quickly preparing to visit the ruins. She accepts Loa’s practical advice, though reluctantly.
• Enel treats the moon as his domain and reacts to the Space Pirates’ excavation as an affront to his authority. His furious charge reinforces his self-styled “god” persona.
• Simon mocks Enel’s delusions, while Weber and Simon follow Loa and Robin after Enel rushes ahead.
• Loa’s familiar, affectionate concern for Robin contrasts with Enel’s possessive anger over the ruins.

Significant themes

• Survival against hostile forces: Loa’s escape shows the danger of crossing between regions and the cost of being an outsider.
• Exploration and discovery: The crew arrives on the moon, where ancient ruins and an unexpected group of occupants await.
• Power, territory, and entitlement: Enel assumes the moon belongs to him, setting up a confrontation with the Space Pirates.
• Practicality versus impulse: Loa urges preparation, while Robin wants to explore immediately and Enel charges into battle.

• Key events: Dashu realizes that several plot threads remain unresolved, especially those involving “Drunkard” Jot and “Insect Calamity” Becky. He lists other threads he remembers: the three ASL brothers’ reunion; Loa and Robin’s wedding; the aftermath of Ivy’s self-sacrifice; the final battle over Poseidon; and Loa becoming a guardian. After reinstalling his computer, Dashu lost a separate document containing earlier ideas and marked passages, though he saved the draft and outline.
• Character developments: Dashu presents himself as a generally capable but forgetful writer, now anxious that he may have overlooked more unfinished threads. He insists he does not want to leave them unresolved.
• Themes: The chapter playfully explores the challenges of long-form storytelling, the gap between an outline and a developing story, and the difficulty of keeping track of ideas. It also highlights reader involvement in completing a story.
• Interactions: Dashu directly appeals to readers to comment with any forgotten plot threads, whether remembered or merely suspected. He jokes that if no one recalls anything else, he may finish the book as it stands.

Key plot points and events

• Enel attacks the Dog-Headed space pirates raiding the lunar ruins, killing nearly all of them and leaving their captain alive at Loa’s request.
• Loa interrogates the survivor, Carl Beckett, captain of the Golden Candle Pirates. Beckett says his crew came seeking treasure and Winged People technology, which could sell for a fortune.
• Beckett identifies himself as a baron from the White Wolf Kingdom. He recognizes Weber’s wings but assumes Weber has only Winged People ancestry, insulting his clothing and skin color.
• Weber loses his temper and knocks Beckett unconscious before the questioning is complete.
• Robin asks Loa to explain the Winged People. Loa warns her, Enel, Weber, and Simon that the truth is dangerous: it is connected to the World Government’s secrets and the One Piece on Laugh Tale. He decides to reveal it to them.

Character developments and interactions

• Enel displays his fierce protectiveness of the ruins, proudly claiming them as his territory, while also showing respect for Loa by sparing one pirate.
• Loa takes control of the interrogation and prepares to share long-hidden knowledge with his companions.
• Robin remains curious and composed, pressing for the history behind the Winged People.
• Weber reacts strongly to Beckett’s prejudiced assumptions, revealing how deeply he values his heritage and the clothing he chose to honor his ancestors.
• Simon tries to help the injured captain, but Robin redirects attention to Loa’s promised revelation.
• The companions’ contrasting reactions—Enel’s pride, Robin’s curiosity, Weber’s anger, and Simon’s concern—shape the scene’s tense but occasionally comic exchanges.

Significant themes

• Hidden history and forbidden truth: The Winged People’s past and the One Piece are linked to secrets the World Government has worked to conceal.
• Power and submission: Beckett’s crew yields once faced with overwhelming strength, reflecting a pirate culture governed by force.
• Identity and prejudice: Beckett’s assumptions about Weber’s appearance and status provoke a fierce defense of his ancestry.
• Knowledge as a risk: Loa emphasizes that learning the truth could overturn everything the group believes.

Key plot points

• Loa explains why the Skypieans, Shandians, and Birka’s people share ancestral traits despite their differences: they descend from the Winged People, whose ancestors came from the moon.
• Winged People living on the ground gradually lost their wings. Calgara’s people had lived on the Blue Planet for generations, while Enel was born without wings because of an ancestral throwback.
• Loa reveals that most people on the Blue Planet are also descendants of the Winged People. A small number of people are genuinely native to the planet: the clan of D, known as the “Enemies of God.”
• During the Void Century, the Winged People nearly exterminated the clan of D and took their home. The World Government’s ban on investigating that lost history conceals this crime.
• The Winged People originally came to the planet because their people lacked resources and faced extinction. An existing civilization lived there, and the newcomers eventually chose war to survive. Loa describes it as a conflict driven by survival rather than simple good and evil.

Character developments and interactions

• Robin insists that the group would rather face a painful truth than remain ignorant, showing that her commitment to knowledge is also personal. Loa recognizes her desire to share the burden with him.
• Weber and Enel are shaken by the explanation of their peoples’ origins. Enel’s missing wings, which contributed to his rejection in Birka, are explained as a rare throwback; his destruction of Birka was also an attempt to hide his difference.
• Simon reacts with disbelief to the idea that most people are not truly native to the planet, then begins to grasp the scale of the revelation.
• Robin collapses under the weight of the truth. Her knowledge of the Poneglyphs had led her to suspect it, and she now understands why the World Government suppresses the past.

Significant themes

• Truth versus comforting ignorance: The group chooses knowledge even when it overturns their understanding of history and identity.
• Identity and ancestry: Peoples divided by culture and conflict share a common origin, while humanity’s assumed origins prove misleading.
• History and power: The World Government’s censorship protects the victors and conceals the taking of another people’s homeland.
• Survival and moral ambiguity: The chapter presents the ancient war as a desperate struggle for survival, complicating any simple division between heroes and villains.
