Chapter Summaries

Uchiha Xin arrived at Fish-Man Island, where Neptune and the royal family welcomed him after Shyarly foresaw his arrival. He discovered that Shyarly could not see his future and, after examining her memories and soul, learned she possessed a unique world law granted by the world’s will.

• Neptune recognized Uchiha Xin’s billion-Belly bounty and ordered the guards and princes not to provoke him.
• Uchiha Xin appeared before Neptune’s welcoming party with Robin, and Neptune introduced himself and offered a banquet.
• Uchiha Xin questioned Shyarly, who said she had foreseen his arrival but could see nothing of his past or future.
• Uchiha Xin activated the Eye of God and examined Shyarly’s memories, confirming her prophetic ability and finding a power fused with her soul.
• The system identified Shyarly as a favored child of heaven and earth who possessed an exclusive world law.

Uchiha Xin learned that Shyarly’s precognition came from an exclusive world law bound to her soul, and the system warned that killing her would destroy it. He considered making her a dependent to inherit the law, then examined her memories and saw two possible futures for Fish-Man Island.

• The system explained that Shyarly’s precognition, observation, and fate-sensing came from an exclusive law granted by the world.
• Uchiha Xin’s killing intent frightened Shyarly, so Neptune and Shirahoshi pleaded for him to spare her.
• Uchiha Xin asked whether killing Shyarly would let him seize her law, and the system warned that it would return to the world’s origin when she died.
• The system proposed making Shyarly an exclusive dependent so Uchiha Xin could inherit her law, and offered to let her switch between mermaid and human forms.
• Uchiha Xin withdrew his killing intent and examined Shyarly’s memories, seeing one future where Fish-Man Island was safe and another where it was destroyed.

Uchiha Xin learned that Shyarly’s prophecy connected his arrival to Fish-Man Island’s survival or destruction, and that her precognition law could strengthen his Eye of God. Neptune then revealed that Shyarly had foreseen two possible futures, both dependent on Xin.

• Shyarly’s visions showed Uchiha Xin as the figure who could either save Fish-Man Island or destroy it, and she told Neptune about the prophecy.
• Uchiha Xin examined Shyarly’s memories and learned she cared only about Fish-Man Island, not Arlong or revenge.

• Uchiha Xin questioned Neptune, who confirmed that Shyarly had foreseen a future where fish-men and merfolk were free and another where Fish-Man Island was destroyed.

Neptune submitted the Ryugu Kingdom and Fish-Man Island to Uchiha Xin, trusting Shyarly’s prophecy that he could change the island’s fate. Hody Jones then surrounded them with a hundred thousand New Fish-Man Pirates and declared his rebellion, leaving Neptune’s group trapped and outnumbered.

• Neptune pledged the Ryugu Kingdom’s army, territory, and resources to Uchiha Xin, and Shirahoshi, Fukaboshi, and Manboshi accepted his decision.
• The New Fish-Man Pirates emerged throughout the area and sealed the routes to Ryugu Palace with a massive net.
• Hody Jones confronted Neptune, condemned his submission to a human, and announced that he had assembled a hundred thousand fighters.
• Hody declared that he would overthrow Neptune’s family and rule Fish-Man Island, while his men called for humans to be killed.
• Shirahoshi and his brothers realized that palace guards had failed to raise the alarm and that their small force could not break through Hody’s army.

Uchiha Xin confronted Hody and the New Fish-Man Pirates after Hody threatened Fish-Man Island and challenged him with an army of a hundred thousand. Uchiha Xin killed all hundred thousand pirates with a single precisely targeted attack, leaving Neptune and his family unharmed and stunned.

• Hody rejected Neptune’s submission to Uchiha Xin, tore up his wanted poster, and threatened to flood Fish-Man Island while Zeo and Daruma prepared to attack.
• Neptune and the three princes pleaded with Uchiha Xin to spare Fish-Man Island’s innocent residents and offered to help defeat Hody’s pirates.
• Uchiha Xin assured Neptune that the residents would be safe and declared that Hody and the New Fish-Man Pirates would not be spared.
• As Hody ordered his hundred thousand pirates to charge, Uchiha Xin covered Fish-Man Island in dark lightning that targeted the pirates without harming the guards, residents, or buildings.
• Uchiha Xin’s attack turned Hody and all hundred thousand pirates to ash, leaving Neptune and his family amazed by his power.

Uchiha Xin erased Hody and the hundred thousand New Fish-Man Pirates, prompting Neptune and Fish-Man Island to submit to him. After agreeing to move Fish-Man Island to the surface and end the threat of slavery, Uchiha Xin asked Neptune to take him to see Shirahoshi, whose secret identity as Poseidon made the request alarming.

• Uchiha Xin killed Hody and erased the hundred thousand members of the New Fish-Man Pirates with a single wave of his hand.
• Neptune formally submitted Fish-Man Island to Uchiha Xin, and Shirahoshi, Fukaboshi, Manboshi, the guards, and residents followed suit.
• Neptune asked Uchiha Xin to fulfill Queen Otohime's wish by moving Fish-Man Island to the surface and protecting its people from slavery.
• Uchiha Xin agreed to move Fish-Man Island to the surface and declared that no one would treat his subjects as slaves.
• Uchiha Xin asked Neptune to take him to see Shirahoshi, and Neptune hesitated because Shirahoshi was the Ancient Weapon Poseidon.

Uchiha Xin summoned a Super Sea King to Fish-Man Island and made it submit, convincing Neptune that he had no need to exploit Shirahoshi’s power. As the group headed to the Hard-Shell Tower to meet Shirahoshi, Vander Decken IX learned that Uchiha Xin had wiped out Hody and the New Fish-Man Pirates, and feared Shirahoshi’s secret had been exposed.

• Uchiha Xin called a Super Sea King, which bowed to him and left after he ordered it to go back.

• Vander Decken IX learned that Uchiha Xin had killed Hody and all one hundred thousand members of the New Fish-Man Pirates with black lightning.
• Vander Decken IX feared Shirahoshi’s secret had been exposed because he wanted to marry her and use her power to rule the seas.

Vander Decken IX decided to destroy Shirahoshi rather than let Uchiha Xin have her, while Noah began racing toward Fish-Man Island. After Neptune and the royal family begged Xin to intervene, Xin vanished to confront the ship, and Robin said it would not reach the island.

• Vander Decken IX decided that if he could not have Shirahoshi, he would destroy her.
• Neptune explained that Vander Decken's tracking weapons had forced Shirahoshi to live inside the Hard-Shell Tower.
• Fish-Man Island shook as Noah, the Ship of Promise, surged toward the island's bubble membrane.

• Neptune, the princes, and the guards knelt before Uchiha Xin and begged him to save Fish-Man Island.
• Xin said the island was his territory and Noah would not destroy it, then vanished as the ship continued speeding toward them.

Vander Decken IX sent Noah toward Fish-Man Island to kill Shirahoshi, but Uchiha Xin arrived aboard the ship and used his power to stop it. The island was left safe, while Vander Decken IX was stunned that Noah could no longer move.

• As Noah approached Fish-Man Island, Neptune and Robin trusted Uchiha Xin to stop it, while Shirahoshi came to the tower door and asked what was happening.
• Vander Decken IX declared that he would destroy Fish-Man Island because Shirahoshi had rejected him, and insisted Noah would keep pursuing her even if he died.
• Uchiha Xin appeared at Noah's bow and ordered Vander Decken IX to stop the ship.
• Uchiha Xin used Ultimate Path: Banshō Ten'in to halt Noah completely, despite Vander Decken IX continuing to activate his Mark-Mark Ability.
• Neptune, Shirahoshi, and the others watched in disbelief as Noah stopped just outside Fish-Man Island, while Vander Decken IX shouted at it to move.

Uchiha Xin killed Vander Decken IX, removed the Mark-Mark Fruit ability, and stopped Noah from tracking Shirahoshi. After Neptune and the Ryugu Kingdom thanked him, Uchiha Xin approached the Hard-Shell Tower to see Shirahoshi.

• Uchiha Xin killed Vander Decken IX with Dark Hole: Devour and stripped away his Mark-Mark Fruit ability.
• Uchiha Xin converted the Mark-Mark Fruit into law nutrients, improving the Eye of God, and learned that future system functions could let him give separated Devil Fruit abilities to others.
• Uchiha Xin released his gravity over Noah, leaving the ship stopped and unable to track Shirahoshi.
• Uchiha Xin returned to Fish-Man Island and told Neptune that Vander Decken IX was dead and Noah would no longer pursue Shirahoshi.
• Neptune, Shirahoshi, Fukaboshi, Manboshi, and the guards bowed to Uchiha Xin in gratitude.
• Uchiha Xin walked to the Hard-Shell Tower doors, where weapons thrown by Vander Decken IX remained embedded.

Uchiha Xin told Shirahoshi that Vander Decken IX was dead and freed her from the Hard-Shell Tower. As Shirahoshi prepared to leave with him, Uchiha Xin used the Eye of God and the Power of the Limit to shrink her to about 1.6 meters tall.

• Uchiha Xin entered the Hard-Shell Tower and introduced himself to the timid Shirahoshi.
• Uchiha Xin told Shirahoshi that Vander Decken IX was dead and that his ability no longer threatened her.
• Shirahoshi said she wanted to visit the Sea Forest and her mother's grave, and Uchiha Xin invited her to come outside with him.
• Neptune confirmed that Shirahoshi was safe and could leave the tower, and Shirahoshi tearfully thanked Uchiha Xin.
• As Shirahoshi approached Uchiha Xin, he used the Eye of God and the Power of the Limit to shrink her to around 1.6 meters tall.

Uchiha Xin shrank Shirahoshi to human size, then took her and Robin to the Sea Forest, where Robin deciphered Joy Boy’s apology on a Poneglyph. Xin absorbed the stone to evolve the Eye of God to its fifth stage, and Shirahoshi explored the Sea Forest freely.

• Uchiha Xin shrank Shirahoshi to 1.6 meters, and Neptune checked that she was unharmed before letting her leave with Xin and Robin.
• Robin deciphered the Sea Forest Poneglyph and identified it as Joy Boy’s apology for failing to keep a promise to the mermaid princess of his time.
• Uchiha Xin absorbed the Poneglyph, destroying the stone and triggering the Eye of God’s fifth-stage evolution.
• Uchiha Xin said the evolution restored part of his peak strength and increased the Power of the Limit available to him.
• Shirahoshi explored the Sea Forest with Uchiha Xin, chasing fish and weaving among coral she could now easily pass through.

Shirahoshi agreed to become Uchiha Xin’s dependent after learning she could switch between human and mermaid forms, and Neptune approved. Uchiha Xin then offered Fish-Man Island a choice of relocating near Mary Geoise or to Sky Island, leaving Neptune to weigh the risks.

• Shirahoshi asked Uchiha Xin whether she could remain small, and he explained that becoming his dependent could permanently alter her constitution and let her switch between human and mermaid forms.
• Shirahoshi agreed to become Uchiha Xin’s dependent after confirming she could still swim, keep her tail, see her family, and remain on Fish-Man Island.

• Neptune approved Shirahoshi’s choice, and Fukaboshi and Manboshi did not object.
• Uchiha Xin offered Fish-Man Island the choice of relocating near Mary Geoise or moving to Sky Island, and Neptune considered the dangers of each option.

Neptune chose Sky Island as Fish-Man Island’s new home, and Uchiha Xin made Shyarly his dependent to obtain her precognition law. Shyarly recovered from the transformation, while Neptune began organizing the relocation and Uchiha Xin prepared to return to Sky Island with her and Shirahoshi.

• Neptune chose Sky Island for Fish-Man Island and agreed to organize the relocation within three months.
• Uchiha Xin considered Noah’s fate, then Shyarly asked what he intended to do with her.
• Uchiha Xin told Shyarly to become his woman, and she agreed before he made her his dependent.
• Shyarly’s awakened law triggered the Eye of God’s sixth- and seventh-stage evolutions, exceeding the system’s estimate.
• Uchiha Xin stayed until Shyarly recovered, while Neptune counted residents and supplies and the princes announced the relocation.
• Shirley left the Mermaid Café, and Neptune saw Uchiha Xin, Shyarly, and Shirahoshi off as they prepared to return to Sky Island.

Uchiha Xin used his seventh-stage Power of the Limit to strengthen Sky Island’s reserve warriors, giving them physiques comparable to Marine vice admirals. After hundreds were enhanced, Tashigi began arranging their training, and Uchiha Xin left the square with Shyarly.

• Neptune told Uchiha Xin that Fish-Man Island would complete its preparations in three months, and Uchiha Xin used Divine Transference to bring Robin, Shirahoshi, and Shyarly back to Sky Island.

• Tashigi ordered the warriors to learn the Navy Six Powers and Haki, and Uchiha Xin left the square with Shyarly.

Uchiha Xin learned that the Marines had branded him the Bloody One and decided to sink Enies Lobby in response, while preserving his plans for Ace’s public execution and the Summit War. On his way there, a spatial disturbance sent him to Shiki the Golden Lion’s floating islands, where Shiki confronted him.

• Shyarly showed Uchiha Xin his one-billion-Belly bounty and explained why the Marines had named him the Bloody One.
• Uchiha Xin burned the poster and chose to attack Enies Lobby, deciding not to interfere with Impel Down or the coming Summit War.

• Shiki the Golden Lion sensed Uchiha Xin with Observation Haki, flew to meet him, and demanded to know how he had reached the sky.

Uchiha Xin confronted Golden Lion Shiki in the sky above his islands, rejecting Shiki’s offer to join the Flying Pirates. Their fight began with Shiki’s sword slashes and Xin’s invisible attack, leaving Shiki unharmed but recognizing Xin’s formidable strength.

• Shiki recognized Uchiha Xin as The Bloody One and offered him a place in the Flying Pirates after mocking his achievements as a rookie.

• Uchiha Xin withdrew his special powers and met Shiki's blades and fists with Armament Haki.
• The two exchanged dozens of blows, shaking a nearby island and tearing apart the surrounding clouds.
• Shiki was driven back with blood at his mouth, praised Uchiha Xin as his strongest opponent since Roger, and promised to kill him.
• Uchiha Xin and Shiki resumed their fight and moved across the sky, leaving dozens of floating islands behind.
• Shiki's sword slashes split the sea and destroyed buildings near Enies Lobby, prompting the Marines to call an enemy attack.
• Spandam was knocked from his chair by the tremors and demanded to know who was attacking Enies Lobby.

Uchiha Xin fought Shiki in the sky above the island, using the Black Blade Yoru to counter his swordsmanship. After Shiki’s final attack, Uchiha Xin unleashed Thunder Dragon Slash and broke through the golden sword waves, leaving their battle unresolved.

• Spandam learned that sword waves had damaged buildings, while Rob Lucci and the other CP9 officers watched the fighters in the sky from the island’s edge.
• Uchiha Xin summoned the Black Blade Yoru and exchanged precise strikes with Shiki, who recognized the blade and offered him a place among the Flying Pirates.
• Uchiha Xin rejected Shiki’s offer and told him he was not worthy, prompting Shiki to coat Oto and Kogarashi in Armament Haki and attack with Lion: Senjindani.
• Uchiha Xin combined the powers of the Dark-Dark Fruit and the Rumble-Rumble Fruit in the Black Blade Yoru and unleashed Thunder Dragon Slash.
• The Thunder Dragon crushed Shiki’s golden sword waves and tore a breach through his attack.

Uchiha Xin and Shiki clashed above Enies Lobby, where Shiki finally halted Xin’s dark Thunder Dragon only after unleashing a barrage of sword-energy slashes. As CP9 withdrew to protect the Tower of Justice, Shiki launched another attack using over a hundred seawater lion heads.

• Shiki’s Lion: Senjindani failed to stop Uchiha Xin’s dark Thunder Dragon, so Shiki unleashed repeated volleys of sword energy until the dragon split apart.
• Pirates watching the battle noted that Shiki had needed many slashes to match Uchiha Xin’s single swing, and Shiki demanded to know what powers Xin possessed.
• At Enies Lobby, Lucci and the other CP9 members recognized Shiki and discussed Xin’s bounty and strength before Spandam ordered them to protect the Tower of Justice.
• Shiki raised seawater into more than a hundred lion heads and sent them lunging at Uchiha Xin with Lion’s Might: Earth Coiling.
