Chapter Summaries

Uchiha Xin drove Kaido from Wano Country, then promised Kozuki Hiyori he would help reclaim the country. As he prepared to summon his allies to clear out the remaining forces, he discovered that the Thunder Emperor, Hancock, Nami, and the others were nowhere nearby.

• Uchiha Xin explained that Kaido had fled using an innate Divine Dragon Clan ability, and his Eye of God could not locate him beyond tens of thousands of li.
• Kozuki Hiyori worried Kaido might return, but Uchiha Xin assured her he would not give Kaido another chance to escape.
• Uchiha Xin promised to help Kozuki Hiyori reclaim Wano Country from the remaining Beasts Pirates and Kurozumi Orochi loyalists.
• Kozuki Hiyori thanked Uchiha Xin and hoped her brother, Kozuki Momonosuke, would return soon; Uchiha Xin planned to hand Wano Country back to him when he did.
• Uchiha Xin tried to summon Hancock, Nami, Violet, and the Thunder Emperor Corps, but sensed that they were all missing from the waters near Wano Country.

Uchiha Xin used his Shadow Clones to suppress resistance across Wano Country and place it under Kozuki Hiyori’s control. Three days later, Nami returned with Gran Tesoro, Gild Tesoro, and Baccarat, but Tesoro awakened his Gold-Gold Fruit and attacked the Thunder Emperor.

• Uchiha Xin realized Hancock and the Thunder Emperor Corps had left Wano Country, suspected Nami had gone after treasure, and summoned over a thousand Shadow Clones.
• Uchiha Xin ordered the Shadow Clones to defeat the Beasts Pirates’ remnants, seize the weapons factories, and deal with Kurozumi Orochi’s holdouts.
• The Shadow Clones suppressed resistance across Wano Country in less than a day, freed forced laborers, and helped Kozuki Hiyori take control as news of Orochi’s death spread.
• Three days later, Nami, Hancock, Nico Robin, and the Thunder Emperor Corps returned with Gran Tesoro, Gild Tesoro, and Baccarat captured.
• Gild Tesoro activated his awakened Gold-Gold Fruit, made Gran Tesoro’s gold attack the Thunder Emperor, and began breaking free of his lightning chains.

Hancock defeated Tesoro and the Thunder Emperor Corps stopped Baccarat from using her ability. Uchiha Xin killed Tesoro and Baccarat, obtained their Devil Fruits, and began fusing them at Nami’s request.

• Tesoro expanded into a giant of gold and attacked the Thunder Emperor Corps, but Hancock destroyed his golden body and bound him with lightning.

• Nami asked Uchiha Xin to extract Tesoro’s Gold-Gold Fruit and Baccarat’s Luck-Luck Fruit, and he agreed.
• Uchiha Xin killed Tesoro and Baccarat with Tensei: Rinne and obtained both Devil Fruits.
• Uchiha Xin used Dark Hole Road: Smelting to fuse the two fruit essences, and Nami watched as they merged.

Uchiha Xin gave Nami the Gold-Gold Fruit and Luck-Luck Fruit, then absorbed a Red Road Poneglyph and brought his Eye of God to its ultimate realm, just one proficiency point short of an upgrade. After learning that Ace’s execution was happening that day, he ordered the Thunder Emperor Corps to set out for Marineford, despite Robin’s warning about the Marines’ trap.

• Uchiha Xin fused the Gold-Gold Fruit and Luck-Luck Fruit into Nami, who demonstrated control over gold and the ability to drain others’ luck.
• Robin brought Uchiha Xin the Red Road Poneglyph she had found in Wano Country, and he absorbed it to complete the Eye of God’s twelfth-stage evolution.
• Uchiha Xin learned that his Eye of God lacked one proficiency point to upgrade and set aside the search for another Road Poneglyph.
• Robin revealed that the Marines’ public execution of Ace was scheduled for that day, and Nami admitted she had forgotten to pass along Doflamingo’s message while pursuing Gold City.
• Uchiha Xin ordered everyone to prepare to depart for Marineford, rejecting Robin’s warning that the assembled Marines and World Government forces had prepared a trap for the Whitebeard Pirates.

Uchiha Xin prepared to head to Marineford for the Summit War, selecting a force to accompany him while leaving Wano Country’s recovery in trusted hands. After sending Hancock and the Thunder Emperor Corps toward Marineford, he returned to Sky Island and told Tashigi he planned to go there.

• Uchiha Xin told Robin he intended to witness the Summit War, while making clear he wanted to seize opportunities from the powerful fighters gathered there.
• Uchiha Xin told Robin and Kozuki Hiyori to remain in Wano Country and help resolve the problems left by the Beasts Pirates.
• Uchiha Xin ordered Hancock to select thirty-six elite Amazon Lily warriors for the trip, with Nami handling navigation aboard the Thunder Emperor.

• Uchiha Xin used Divine Transference to return to Sky Island, where he found Tashigi training twenty warriors.
• Uchiha Xin told Tashigi that Marine Headquarters was about to execute Ace and that he planned to go to Marineford.

Uchiha Xin found Perona in Totto Land, where she revealed that Kaido had taken refuge on Whole Cake Island and that she wanted Charlotte Linlin’s Soul-Soul Fruit. He chose to go to Marineford for the Summit War first, leaving Kaido and Charlotte Linlin for later.

• Uchiha Xin agreed to bring Tashigi and the twenty Sky Island warriors to the Summit War so they could test themselves against the Marines.
• Uchiha Xin used Divine Transference to locate Perona in Totto Land and found her near Whole Cake Island.
• Perona told Uchiha Xin that Kaido had fled to Whole Cake Island after escaping Wano Country and was seeking Charlotte Linlin’s help.
• Perona admitted she wanted Charlotte Linlin’s Soul-Soul Fruit to fuse with her Hollow-Hollow Fruit and strengthen her soul control.
• Uchiha Xin refused to attack Whole Cake Island before the Summit War, despite Perona’s urging, because Hancock and Nami were waiting for him at Marineford.

Uchiha Xin postponed his assault on Kaido and Charlotte Linlin until after the Summit War, promising Perona she would eventually get the Soul-Soul Fruit. After teleporting to the Thunder Emperor, he found Z and the Marine Guerrilla Unit attacking the ship, with Hancock battling Z.

• Uchiha Xin told Perona that Kaido and Charlotte Linlin would not escape and promised her the Soul-Soul Fruit after the Summit War.

• A Marine fleet attacked the Thunder Emperor, and its crew intercepted a cannonball with lightning.
• Nami told Uchiha Xin that Z led the Marine Guerrilla Unit and had attacked because he recognized the ship.
• Hancock knocked Z back with a kick, declared she belonged only to her husband, and faced Z as his unit urged him to stop fighting.

Z attacked Uchiha Xin but was driven back by Tashigi and Hancock, while the Marine Guerrilla Unit’s ships came under lightning fire. Ain then tried to regress Uchiha Xin with the Ripe-Ripe Fruit, but his body resisted her ability, and he seized her.

• Z abandoned his fight with Hancock and charged at Uchiha Xin, but Tashigi intercepted him and damaged his Battle Smasher.

• Ain repeatedly tried to make Uchiha Xin regress, but her ability had no effect on him.
• Uchiha Xin grabbed Ain’s wrist, pulled her close, and pinned her limbs with an invisible force.

Uchiha Xin captured Ain and suppressed her Ripe-Ripe Fruit, prompting Z to attack in an attempt to save his former student. Uchiha Xin crushed Z’s Seastone Battle Smasher with one hand, and Z prepared to continue fighting with his remaining arm.

• Ain’s Ripe-Ripe Fruit failed to affect Uchiha Xin, who knocked her unconscious and restrained her with Truth-Seeking Orb handcuffs.
• Uchiha Xin had Ain taken away to be locked up while he considered whether to make her his final familiar.
• Z charged at Uchiha Xin to save Ain, fighting through Hancock and Tashigi’s attacks.
• Uchiha Xin caught and crushed Z’s Seastone Battle Smasher mechanical arm, leaving Z with only a stump.
• Z covered his remaining left arm in Armament Haki and prepared to fight on.

Uchiha Xin killed Z with a single Armament Divine Vacuum Attack, gaining enough Haki experience to bring both his Observation and Armament Haki close to their limits. He then revealed that Steel Bone Kong and five CP0 agents had been observing the battle from concealment, and confronted Kong over letting Z die.

• Z charged Uchiha Xin to demand Ain's return, but Xin shattered Z's arm and chest with an Armament Divine Vacuum Attack, killing him.
• The Marines recoiled from Xin, while the system awarded him Z's Observation and Armament Haki and converted them into proficiency.
• Xin realized both types of Haki were near their bottlenecks and said that another major boost could push them into the World-Breaking Realm.
• Xin sensed hidden figures offshore, and Steel Bone Kong appeared with five masked CP0 agents, including a user of the Space-Space Fruit.
• Kong admitted nothing, while Xin accused him of letting Z die and waiting until the battle ended to reveal himself.

Steel Bone Kong tried to stop Uchiha Xin from going to Marineford and had a CP0 agent use the Space-Space Fruit to pull him into another dimension. Uchiha Xin disappeared with Steel Bone Kong and the agents, but Perona believed he could return whenever he wanted.

• Uchiha Xin learned from Steel Bone Kong’s memories that the Clan of D carried a power that helped its descendants reach the world-breaking level, and that the World Government likely used Uranus to cultivate its own world-breaking fighters.

• Uchiha Xin learned that Steel Bone Kong had once fought Red the Aloof for ten days and had grown stronger over the following twenty years, surpassing the current Whitebeard.
• Uchiha Xin told Hancock and Tashigi to leave the surviving Marines alive, and the Thunder Emperor Corps withdrew its lightning as the battered warships fled.
• Uchiha Xin headed for the bow of the Thunder Emperor and hurried toward Marineford because the Summit War had begun and Ace could be executed at any moment.

• Uchiha Xin told Whitebeard not to get the wrong idea because he was not there to help him, leaving Whitebeard and the Whitebeard Pirates wary of his intentions.
