Chapter Summaries

Kaido flew to the waterfall after learning Katakuri had captured King, expecting to confront the Big Mom Pirates. Katakuri dodged Kaido’s Thunder Bagua and wounded him with his trident, whose blade began to glow as Kaido demanded to know where he had gotten it.

• Two Beasts Pirates reported to Kaido that Katakuri had arrived with a giant monster and captured King.
• Kaido transformed into a dragon and flew to the waterfall, where he saw Katakuri’s challenge marked on the ground.
• Katakuri sensed Kaido approaching, removed his scarf, and prepared to fight him.
• Mousse claimed responsibility for capturing King and offered to release him if Kaido defeated Katakuri.
• Kaido launched a surprise Thunder Bagua, but Katakuri foresaw the attack and dodged before countering with his trident.
• Katakuri wounded Kaido, and Kaido asked where he had obtained the weapon as its blade began to glow red.

Mousse assessed Kaido’s strength while Katakuri’s question prompted Kaido to recall the history of the Oni Tribe. The account ended with Shimotsuki Ryuma killing nearly all the Oni on Onigashima, sparing only Kaido, who was not yet three years old.

• Mousse compared Kaido’s vitality and Haki with Katakuri’s and concluded that Kaido could contend with Garp and Whitebeard.
• Kaido sensed Mousse watching him and challenged the red-haired boy.
• Katakuri asked Kaido about his Oni Tribe origins, and Kaido sat down to remember his childhood.
• The survivors of the Evil Spirits fled the Ice Continent, reached Wano Country, and were driven to Onigashima by the samurai.
• Shimotsuki Ryuma swam to Onigashima and slaughtered nearly the entire Oni Tribe, leaving the toddler Kaido alive.

Mousse explained Kaido’s brutal childhood, his hatred of Wano, and how the War God Halberd’s old hatred for the Evil Spirits had wounded him. He urged the weapon to let go of that hatred while Katakuri sought to master it as his own power.

• Kaido survived alone on Onigashima after Ryuma left, grew strong, and fled to sea rather than invade Wano.
• Twenty years later, Kaido returned to Onigashima and allied with Kurozumi Orochi in seeking revenge against Wano.
• Mousse connected Kaido’s ancestry to the Ice Continent’s Evil Spirits and explained why the War God Halberd’s Haki suppressed his regeneration.
• Katakuri accepted that he needed to attune to the halberd and master its power instead of relying on its independent attacks.
• Mousse addressed the halberd, arguing that the Evil Spirits no longer posed a great threat and that it should release its ancient hatred.

Katakuri and Kaido fought a drawn-out battle until Kaido used Drunken Thief to knock Katakuri down and tried to enter Mousse’s Book World. Katakuri rose for one last attack, striking Kaido with a Flying Slash as Kaido’s head was wedged in Amon’s mouth.

• Katakuri and Kaido resumed their fight, with Katakuri evading attacks and wearing Kaido down rather than clashing directly.
• Mousse entered the Book World, took genetic samples from the unconscious King, and confirmed the extent of the Lunarian’s passive environmental immunities.
• Kaido grew frustrated with Katakuri’s evasive tactics and used Drunken Dragon Eight Trigrams’ Drunken Thief to steal Katakuri’s advanced Observation Haki and knock him down.
• Kaido demanded that Mousse release King, then tried to crawl into the Book World through Amon’s mouth.
• Katakuri struggled back to his feet and poured his remaining Haki into the Demon Halberd, sending a Flying Slash into Kaido while Amon held Kaido’s head in place.

Katakuri’s desperate strike badly wounded Kaido but earned him the Demon Halberd’s recognition, while Katakuri himself was left in need of surgery. Mousse stayed behind with Kaido, who took him to Onigashima and introduced him to Yamato.

• Kaido and Amon were sent flying by Katakuri’s slash, leaving Kaido severely wounded.
• Mousse saw Katakuri’s critical condition, blamed himself for leaving during the fight, and tried to attack Kaido before Katakuri stopped him.
• Kaido checked that King was unharmed, while Katakuri apologized for acting rashly to protect Mousse.
• Mousse realized Katakuri’s desperate attack had earned the Demon Halberd’s recognition, and Katakuri left for Candy Island to undergo surgery.
• Mousse stayed behind, and Kaido took him to Onigashima, where he introduced him to Yamato.

Mousse took eight-year-old Yamato away from Kaido to learn about her missing mother, then reconstructed the woman’s face with his Book-Book Fruit. The portrait looked like Charlotte Linlin, leading Mousse to suspect Yamato’s mother was a woman Kaido chose as a substitute for his unfulfilled love for Linlin.

• Mousse questioned Yamato and learned that Kaido’s brutal upbringing had begun long before she admired Oden.
• Mousse tested Yamato’s strength by twisting her horns, while Kaido left them alone to drink.
• Mousse flew away with Yamato on his scroll to ask about her mother, whom she had never known.
• Mousse drew a portrait of Yamato’s mother and revised it according to Yamato’s corrections.
• Mousse recognized the woman’s resemblance to Charlotte Linlin and guessed that Kaido had chosen her as a replacement for Linlin, then killed her after realizing the resemblance could not replace his feelings.

Mousse reflected on Kaido’s past and Yamato’s desire to live as a human, then waited to see whether Oden Kozuki would act against Kaido after his recovery. He used Soul Search on Queen and learned how Queen’s family left the Flower Kingdom and how Queen became a scientist in Germa 66.

• Mousse considered how Kaido’s violent choices harmed Yamato and reaffirmed that strength should bring positive change.
• Mousse waited for Oden Kozuki to confront Kaido, but Kaido recovered quickly and Oden did not appear.
• Mousse decided to remain and watch the delayed battle between Oden Kozuki and Kaido.
• Mousse secretly used Soul Capture and Soul Search on Queen to obtain his knowledge and memories.
• Mousse learned that Queen was born in the Flower Kingdom, grew up in the North Blue under Germa 66, and became a scientist before Vinsmoke Judge returned.

After learning Queen’s history with Germa 66, Mousse drew on the scientist’s knowledge and developed a new approach to detecting Devil Fruit powers. As war approached in Wano, he gave Yamato Little K as a gift before the conflict could separate them.

• Mousse discovered that Queen’s grudge against Judge began when Judge expelled him from Germa 66, and he learned from Queen’s technology and research methods.
• Mousse became confident he could become the world’s greatest scientist and began developing a way to detect Devil Fruit powers without help from Beck.
• Mousse recognized that Kaido’s forces were preparing for battle and decided to give Yamato a gift before leaving Wano.
• Yamato mistook Little K for a raw meatball, but she grew excited when it transformed into different shapes.
• Mousse gave Little K to Yamato so she would have a useful companion while he was away.

Mousse watched the battle between Oden Kozuki’s forces and the Beasts Pirates while reflecting on the secret behind the Poneglyphs’ indestructibility. As King and Queen entered the fight, Mousse saw the opening he had been waiting for.

• Mousse left Yamato with Little K, which could shrink, hide, and eventually chew through the Seastone cuffs to help her escape.
• Mousse concealed himself in Amon’s Book World and followed the Beasts Pirates’ army toward the battle without being detected.
• Mousse recalled learning from Vegapunk that Poneglyphs were made by fixing awakened Barrier-Barrier Fruit power into Seastone softened with heated Sake-Iron Ore.
• Oden Kozuki led the Nine Red Scabbards and Shinobu through the Beasts Pirates’ forces in a charge toward Kaido.
• King and Queen joined the battle, breaking the brief deadlock and giving Mousse the opportunity he had been waiting for.

Mousse captured Kanjuro and Kurozumi Semimaru to claim their Devil Fruits while Oden launched a powerful attack that brought Kaido crashing down. After Oden’s strike, Mousse’s prepared trigger helped him intercept Semimaru before she could impersonate Momonosuke and call for help.

• Mousse had Amon carry him behind Kanjuro, knocked him unconscious, and stored him in the Book World.
• Queen cheered at Kanjuro’s capture, while Denjiro stayed occupied fighting Queen.
• Kin'emon split Kaido’s Bolo Breath with his Flame Cutter swordsmanship, allowing Oden to close in and wound Kaido with Peach Blossom Ten Fists.
• Mousse recognized Kurozumi Semimaru disguised as Momonosuke and used a distant explosion to prevent her from calling to Oden.
• Mousse activated his prepared self-hypnosis trigger, intercepted Semimaru with Amon, and stored her in the Book World.

Oden Kozuki and Kaido traded powerful attacks, and the clash of their Conqueror’s Haki left Oden’s side with more fighters still able to battle. While the fighting continued, Mousse captured Shinobu’s Devil Fruit and located five ordinary Zoan users, waiting for the battle’s outcome before targeting them.

• Oden Kozuki survived Kaido’s Thunder Bagua and struck again, but Kaido’s club sent him flying.
• The fighters’ Conqueror’s Haki knocked out thousands of Beasts Pirates, leaving Oden Kozuki’s side with the advantage among those still able to fight.
• King killed Raizo, while Mousse captured the unconscious Shinobu and used Soul Capture to take the Juku Juku no Mi.
• Mousse searched the battlefield with Observation Haki and found five ordinary Zoan users among the Beasts Pirates.
• Mousse memorized the five users’ locations and waited for the battle’s outcome before acting against them.

Mousse captured Queen and several Beasts Pirates before escaping, while Oden spent his life force on a devastating attack that failed to defeat Kaido. Mousse then raided Orochi’s Seastone factory and decided to visit Yasuie Shimotsuki and Lady Toki.

• Mousse and Amon captured five ordinary Zoan users and Queen, enraging Kaido and prompting him to pursue them.
• Kaido turned into a dragon to chase Mousse, giving Oden the opening to pour his remaining strength and life force into Enma.
• Oden wounded Kaido deeply with Enma but was thrown aside, and Kaido knocked out Denjiro, Kin'emon, and Shutenmaru.
• Mousse escaped the battlefield with Amon while Kaido remained behind, unable to catch them.
• Mousse raided the poorly guarded Seastone factory, taking ore, finished goods, equipment, materials, and most of its skilled craftsmen.
• Mousse decided to visit Yasuie Shimotsuki and Lady Toki under the pretense of delivering news.

Mousse questioned Toki about the ancient Great Kingdom and Momonosuke’s lack of training, then offered to teach the boy a martial art in exchange for Toki’s cooperation with his research. He taught Momonosuke the renamed Way of the Second Son and began asking Toki questions about her directly.

• Mousse examined Momonosuke and asked Toki what the world had been like eight hundred years earlier, but she could recall little beyond a comfortable childhood.
• Mousse concluded that the Great Kingdom’s productive capacity had not necessarily exceeded that of the present and asked why Momonosuke had never trained seriously.
• Yasuie Shimotsuki explained that Oden and Toki had hoped Momonosuke’s apparent weakness would keep their enemies from viewing him as a threat.
• Mousse offered to teach Momonosuke a martial art and told Toki he wanted to study her Time-Time Fruit ability; Toki agreed for her son’s sake.
• Mousse taught Momonosuke the Sea Calming Art under the name Way of the Second Son, then began questioning Toki about her directly.

Mousse learned why Oden had endured humiliation instead of seeking outside help to defeat Kaido, and understood that Oden had reached his limit after five years of training his resolve and strength. Toki hinted that Wano’s liberation and opening would come in twenty years, and Mousse’s mention of Poseidon and Joy Boy revealed that she recognized the names.

• Toki explained that Oden had endured humiliation to protect Wano’s people while sharpening his resolve and strength against Kaido.
• Yasuie Shimotsuki revealed that Moria had turned from an ally into an enemy after robbing Ryuma’s grave, worsening Wano’s distrust of outsiders.
• Mousse concluded that flying gave Kaido a decisive advantage and that Wano had to defeat him without relying on outside help.
• Toki said Wano’s liberation and opening would have to wait twenty years, then refused to explain the prophecy connected to Laugh Tale.
• Mousse mentioned Poseidon and Joy Boy, and Toki’s brief change in expression confirmed that she recognized the names.

After learning that Toki and Oden’s children had been arrested and condemned to execution, Mousse suspected Kaido’s absence and his own interference had changed the events surrounding Oden’s imprisonment. He resolved to raid the execution grounds, and Shimotsuki Ushimaru joined the assembled samurai as they prepared to travel to the Flower Capital.

• Mousse learned from Yasuie Shimotsuki that Toki and the children had been arrested after visiting Oden in prison and were to be executed with him.
• Mousse reasoned that his interference had helped Oden nearly defeat Kaido, leaving Kaido with no regretful desire to give Oden another chance to escape and fight again.
• Mousse worried that without Shinobu to reveal the truth, Oden might die remembered as the Foolish Lord, so he decided to raid the execution grounds and sought a chance to capture Kurozumi Orochi.
• Mousse enlarged Amon’s scroll form to make it easier to rescue the prisoners, and Yasuie Shimotsuki quickly gathered samurai to accompany him.
• Shimotsuki Ushimaru joined the group, and Mousse questioned whether the daimyo risked being recognized in the Flower Capital.

Mousse disguised the samurai and explained a plan to help Oden only if Kaido was absent, while arguing that replacing Orochi with a weaker shogun could still protect Wano’s people. When they saw Oden at the execution site, they found him grievously wounded and missing both arms.

• Yasuie Shimotsuki and Mousse disguised the samurai, and Mousse outlined how they could approach the execution ground if Kaido was not there.
• Mousse argued that capturing Orochi mattered because a less cruel, easier-to-threaten shogun could reduce the harm done to Wano even if Kaido remained in power.
• Yasuie Shimotsuki and Shimotsuki Ushimaru realized they could keep fighting by threatening Orochi’s regime and retreating when they could not win.
• Mousse and the two Shimotsuki saw Oden covered in wounds with nothing below his shoulders.
• Mousse deduced that King and Orochi had both helped cripple Oden, while Oden felt some gratitude to King for stopping Orochi from tormenting his family.

Mousse’s rescue attempt at Oden’s execution turned tragic when King’s Fire Dragon Emperor killed Oden and Toki, though Amon saved Momonosuke and Hiyori. Mousse brought the surviving children into the Book World, where he confronted the cost of the parents’ sacrifice.

• Amon and the samurai launched a prepared attack, incapacitated Kurozumi Orochi, and created an opening for Oden’s family to escape.
• King intercepted Oden’s escape and unleashed Fire Dragon Emperor at Oden, Toki, Momonosuke, and Hiyori.
• Oden and Toki shielded their children from the flames and died, while Amon rescued Momonosuke and Hiyori.
• Denjiro realized Momonosuke had survived, and the Scabbards abandoned their charge against King to focus on their young lord.
• Mousse saw Oden and Toki’s burned bodies in the Book World and reflected on their sacrifice and his own parents.

Charlotte Mousse realized the Sea Calming Art drew power from hatred and despair, then erased the dangerous technique from his memory while keeping its broader insight about strengthening Haki through emotion. After Momonosuke awakened Conqueror’s and Observation Haki, two Scabbards stayed in Wano to pursue King, and Mousse prepared to leave despite doubting they could defeat him.

• Charlotte Mousse discovered that Momonosuke had awakened both Conqueror’s Haki and Observation Haki, and concluded that the Sea Calming Art harnessed hatred and despair to strengthen conviction.
• Fearing the Sea Calming Art’s lasting psychological distortions, Charlotte Mousse erased it from his memories but retained the idea of using positive emotions to accelerate Haki training.
• The Scabbards, grateful for Momonosuke’s awakening, accepted Charlotte Mousse’s claim that Kanjuro was a traitor, and Kin’emon handed over his sorcery.
• Ashura Doji Shutenmaru declared that he would stay in Wano to seek revenge on King, and Denjiro chose to stay with him.
• Charlotte Mousse doubted that Shutenmaru and Denjiro could kill King, but he concealed his pessimism and felt able to leave Wano without concern.

Mousse coordinated the Scabbards’ plans to gather allies against Kaido and returned to Totto Land to oversee the removal and reassignment of Devil Fruit powers. He discovered the strategic uses and limits of the Juku Juku no Mi and learned that Charlotte Snag had developed the Fuku Fuku no Mi into a combat ability.

• The Scabbards divided their efforts: Shutenmaru and Denjiro stayed in Wano to recruit patriots, while Kin'emon, Kawamatsu, Momo, his sister, Shinobu, Cat Viper, and Dogstorm headed to Zou.
• Kikunojo planned to seek help from Whitebeard and bring her brother Izo back, while Mousse returned to Totto Land to work with Hogback on removing Shinobu’s and Kin'emon’s Devil Fruit abilities.
• Charlotte Moscato tested the Juku Juku no Mi and, with Mousse, discovered that it could accelerate existing growth but caused ungrown seeds to rot and could not improve poor cultivation.
• Praline considered using the Juku Juku no Mi to gain strength quickly, but Mousse refused and ordered Charlotte Moscato not to ripen his siblings at the cost of their lifespans.
• Charlotte Snag used the Fuku Fuku no Mi to create fantasy armor for combat instead of producing clothing, though his appearance failed to match the impressive designs.

Mousse distributed the Brush-Brush Fruit and gave the Copy-Copy Fruit to Charlotte Castard, whose broad abilities made her an ideal user. After discovering she could transform by touching any part of her body, Castard gained a major combat advantage and surpassed Charlotte Amande for the first time.

• Charlotte Mondol rejected the Brush-Brush Fruit because he preferred military matters, so Mousse gave it to Charlotte Broyé instead.
• Mousse gave the Copy-Copy Fruit to Charlotte Castard, believing her versatile skills would let her use it effectively in battle.
• Charlotte Castard tested the fruit and, following Mousse's suggestion, learned she could transform by touching any part of her body.
• Charlotte Castard found that transforming during combat disrupted opponents without diminishing her own abilities, improving her fighting performance.
• Charlotte Castard surpassed Charlotte Amande, whose strength had stagnated while Castard's had continued to grow.
