Chapter Summaries

Luffy and his crew arrived at Marine Headquarters to search for Robin and learned little about the danger surrounding the gathering.

Blackbeard arrived at Crescent Harbor claiming to be Pirate King and demanded a quarter of the world for the pirates, presenting Pluton as proof that he had reached Laugh Tale. When he threatened to demonstrate the ancient weapon, Longinus summoned Poseidon’s power, and giant Sea Kings lifted Pluton out of the sea.

At Marine Headquarters, Longinus revealed that the Celestial Dragons descended from Space Pirates who seized the world, while Blackbeard questioned why the history mattered to them.

• The Five Elders discovered that West, Fujitora, and Marines had fled the Holy Land and that the government's communications had been cut off, then read a newspaper showing widespread support for Longinus.

As Rayleigh, Gaban, and other allies gathered for the final battle, Buggy was mistakenly hailed as a powerful combatant.

• Blackbeard challenged Longinus over why he had waited so long to reveal the danger, and Longinus said Franky’s work on Pluton had given him hope ten years earlier.
• Longinus told Tom that Franky had stolen the Pluton blueprints to protect the world and was safe at a secret base, promising to bring him back after the final battle.

• Red-Haired reunited with Rayleigh and Gaban, then revealed that Buggy had been released from Impel Down as a special combatant, leaving Buggy distressed as people praised him.

• Pluton fired at Mary Geoise, but Imu stopped the shot with a force-field barrier while enormous Sea Kings rammed the Red Line.

• Longinus told the Allied Forces to march on Mary Geoise and carry out the Buster Call.

• Imu recounted how the world united against returning Space Pirates and created Pluton and the Sea Kings, while later turning to Devil Fruits and technology to develop Uranus.
• Imu said she had refused to control Uranus because of its terrible cost but eventually agreed at Joy Boy’s request.
• Imu revealed that she and Uranus destroyed the Space Pirates’ main force in a single attack in outer space, leaving Longinus to wonder whether Uranus’s power depended on fighting there.

Imu revealed her history with Joy Boy and explained how her hatred shaped the World Government, while Longinus uncovered signs that a kinder side of her had preserved weapons and people Joy Boy cared about. As Imu realized Longinus was close to discovering the truth about her, she ended their conversation.

• Imu recognized Longinus’s enhanced luck and evaded a coordinated assault by the assembled fighters before teleporting around the battlefield and striking Kuzan, Sakazuki, and Garp.

• Imu healed her injuries with a milky-white radiance, then teleported into the darkness again as Longinus called for everyone to destroy it with all their strength.

Longinus fought Imu inside Blackbeard’s darkness and defeated her without suffering serious injuries, revealing that his pure heart made him immune to her instant-kill ability. After Imu died and the Marines and pirates celebrated victory, Longinus suspected the final battle was not over because the final boss could have a second phase.

• The Marines and pirates cheered their apparent victory, but Longinus suspected Imu’s death would lead to a second phase.

A second Imu emerged, revealing that she had escaped her old body and become Uranus, a weapon made from the world’s magnetic poles. She explained that Uranus caused the Grand Line’s dangerous conditions and mutations, leaving the assembled fighters to face a foe whose full power remained unknown.

• A second Imu rose from beneath Mary Geoise and revealed that her former body had died, while Dragon and Ivankov recognized her voice as Kuma’s.
• Longinus deduced that Imu had used Vegapunk’s research to separate herself from her old body and break free of Uranus, and Imu confirmed that the defeated Imu was her self from eight hundred years ago.
• Imu explained that Uranus was the world’s extracted magnetic poles, which had created the Grand Line’s chaotic magnetic fields and shielded the planet from cosmic radiation.
• Imu revealed that her people had spread the Grand Line’s reputation and placed Sea King nests in the Calm Belt to keep people away, intending the region’s mutations to serve as revenge against the world.
• Imu said the Grand Line’s inhabitants had adapted to the mutations and grown stronger instead of dying, making her responsible for the monsters they had become.

Imu revealed that her geomagnetic power had caused the world's suffering, then fought Longinus, whose Armament Haki let him resist her control over blood. Imu showed she could still use another ability and struck down Ivankov and Yasopp, leaving the battle in turmoil.

• Imu used her magnetic power to drag Blackbeard into her fist and then made blood burst from his body.
• Longinus ordered fighters who could not fully harden themselves with Armament Haki to retreat, then charged Imu.

• Longinus and Imu exchanged attacks amid flying rubble as their clash shook the sky and sea.
• The crowd concluded Imu could no longer teleport and rushed to join the fight, but Imu fired white beams that killed several people, including Ivankov and Yasopp.

Imu attacked the allied forces with her world-spanning magnetism and revealed her Archangel form, while Garp drew her attention. A barrage aimed at Garp instead struck someone whose position Luo had swapped with him, leaving the battle still raging.

• Luo revealed that his teacher had swapped Garp’s position, and the barrage struck the other figure instead.

Longinus and the assembled fighters attacked Imu together, but she killed Charlotte Linlin and impaled Garp. Garp restrained Imu as Longinus’s hidden gambit began when a ghost emerged from a mirror and passed through her.

• Garp grabbed Imu’s wrist and urged the others to fire at her while she remained restrained.
• Imu noticed a mirror at Garp’s chest and realized Longinus may have arranged their earlier switch as a ghost emerged and passed through her.

• Katakuri realized Longinus had used Brulee’s mirror ability to bring Sugar to Imu while the Negativity Ghost briefly dazed her.

• Imu mocked Longinus for his plan’s failure and announced she would quickly finish everyone off.
• Longinus declared his commitment to justice, provoking Imu to threaten the world he wanted to protect.

Im used Mary Geoise and more than a hundred islands as weapons, but the gathered fighters worked together to stop her assault. While they were distracted, she killed several allies, and Longinus realized her life was nearing its end.

• Im flipped Mary Geoise into the sky and hurled it down, but Shirozou struck it apart and Fujitora slowed the falling debris.

• Longinus studied Im’s growing emotions and concluded that her life was counting down.

Longinus rallied the fighters against Imu, but she broke through their attacks and killed two of their allies. As the group struggled to stop her, Doflamingo revealed his knowledge of Imu’s plans and provoked her, while Longinus secretly hoped Doflamingo would die so Monet’s matter could not be used against him.

• Imu charged at Red-Haired, but his resistance bought time for Rayleigh, Kaido, Sakazuki, Katakuri, and Dragon to attack her.
