Chapter Summaries

Mousse helped Charlotte Custard explore the Copy-Copy Fruit’s limits, while the Devil Fruits brought back from Wano strengthened Totto Land’s treasury. He reassured Perospero about their Seastone supply, and Katakuri remained ready to protect him if Kaido came seeking revenge.

• Charlotte Custard found that copying her mother increased her size and strength, but her agility and the Fruit’s limits kept her from challenging stronger fighters.
• Mousse suggested Custard try copying an imagined larger person, and she managed to grow to nine meters before discovering a limit of about twelve meters.
• Mousse realized the Copy-Copy Fruit could reproduce a target’s voice and presence closely enough to fool even powerful observers.
• Mousse’s recovered Devil Fruits repaid the losses from giving away the Swamp-Swamp Fruit, quieting siblings who had resented him.
• Mousse told Perospero that Totto Land’s seized Seastone would last and that he had learned how to process it for future production.
• Katakuri worried Kaido might attack Totto Land, but stood by Mousse rather than surrendering him when Kaido demanded it.

Kaido attacked Charlotte Linlin, but she withstood his strongest blow and knocked his weapon into the sea. Kaido returned to shore in his human-beast form and challenged her again, but he still could not overpower her.

• Charlotte Linlin taunted Kaido over his complaint, and he lunged at her with a powerful attack.
• Charlotte Linlin met Kaido's blow with Elbaf Spear: King's Spear, was blasted back, but emerged unharmed.
• Kaido lost his iron club to the sea, while Totto Land's onlookers cheered Charlotte Linlin's advantage.
• Kaido transformed into a dragon and entered the sea, then returned to shore after Athena froze its surface.
• Kaido resumed the fight in his human-beast form, but Charlotte Linlin's stronger defense kept him from overwhelming her.

Charlotte Linlin gained the advantage over Kaido, but refused to hand Queen back, provoking Kaido into attacking Mousse before Katakuri took over the fight. Katakuri wounded Kaido with his trident and declared that Kaido’s copied future sight would not be enough to defeat him, as their battle resumed in earnest.

• Mousse explained that Charlotte Linlin’s strength and endurance were gradually turning the battle against Kaido, who had already spent his trump cards.
• Kaido demanded Queen’s return, but Mousse had turned Queen’s soul into a Homies and sent Kaido only Queen’s corpse.
• Furious at the sight of Queen’s corpse, Kaido attacked Mousse, but Charlotte Linlin grabbed his tail and slammed him into the ground.
• Charlotte Linlin withdrew so Katakuri could fight Kaido, and Katakuri defended patiently until he struck Kaido’s armpit with his trident.
• Katakuri explained that he could predict Kaido’s movements and would not be shaken by Kaido’s copied Observation Haki again, prompting Kaido to resume the fight in anger.

Katakuri used precise, efficient attacks to match Kaido and forced him to abandon his attempt to get compensation from Totto Land. The Scabbards remained there while Mousse studied Sulong, and Whitebeard proposed a personal duel with Kaido, leaving Mousse to question whether Whitebeard could kill him.

• Katakuri evaded Kaido’s ranged attack, conserved his Haki, and struck Kaido’s joints until Kaido’s right hand lost its strength.
• Kaido recognized that Katakuri’s precise fighting style resembled Garp’s and realized Katakuri had become his equal.
• Kaido gave up on forcing compensation from Totto Land and flew back to Wano Country without learning where Momonosuke, his sister, and the Scabbards were.
• Cat Viper and Dogstorm agreed to help Mousse study Sulong, so Momonosuke and the Scabbards stayed in Totto Land for the research.
• Kikunojo reported that Whitebeard wanted to challenge Kaido to a personal duel, and Mousse noted that Whitebeard’s ability to kill Kaido remained uncertain.

Mousse watched Whitebeard fail to permanently harm Kaido and used the aftermath to build influence through the World Economic News Paper’s Combat Power Rankings. After Morgans aligned with Totto Land and Charlotte Linlin entrusted Mousse with the family intelligence network, Mousse became one of Totto Land’s most important figures.

• Mousse watched Whitebeard overwhelm Kaido, but Kaido fled without lasting injuries and later earned the title Strongest Creature of Land, Sea, and Air.
• Mousse understood that Whitebeard could not safely avenge Oden alone and would risk losing many of his sons in a group battle.
• Morgans launched a popular Combat Power Rankings column, and Mousse secretly wrote its monthly rankings under the name Tengtianxiao.
• Morgans chose to align with Totto Land, and Mousse became the World Economic News Paper’s second-largest shareholder.
• Mousse used his growing wealth and influence to strengthen his position within the Charlotte family.
• Charlotte Linlin placed the family’s intelligence network under Mousse’s management, making him Totto Land’s fourth most important figure before he turned twelve.

Mousse uncovered how the Mink Tribe’s Sulong transformation worked and developed medicine and a flare that let nearly every adult Mink transform more safely. After Cat Viper and Dogstorm entrusted him with their Life Cards, he postponed his plan to visit Zou when Charlotte Amande sought his help with cooking, and he learned she still visited Dressrosa to duel Kyros.

• Mousse determined that Sulong activated suppressed animal lineage factors and that a Mink’s strength of body and soul affected whether they could retain control.
• Mousse developed medicine that reduced Sulong’s power but lowered its risks, then paired it with a Moonlight Illumination Flare so adult Minks could transform on demand.
• Cat Viper and Dogstorm recognized how Mousse’s inventions could strengthen Zou and gave him their Life Cards, unaware he had built a safeguard into the medicine.
• Mousse set aside his plan to sneak into Zou and see the Road Poneglyph after Charlotte Amande asked him for cooking advice.
• Mousse suggested Amande make hand-pulled noodles, and he learned from Kastard that Amande still went to Dressrosa to duel Kyros.

Mousse returned to Dressrosa and discovered how Doflamingo’s money and businesses had transformed the kingdom while tightening the Donquixote Family’s control. He also learned that Kyros continued defeating the family’s officers in the arena despite its deadly new rules, while Mousse hoped to help Charlotte Amande pursue him.

• Mousse learned that Charlotte Amande had stopped killing after her second defeat by Kyros, and he suspected she had fallen in love with him.
• Mousse traveled to Dressrosa, where he found the population better fed but the streets filled with bars, casinos, and an open slave auction.
• Mousse concluded that Doflamingo had gained the citizens’ favor by offering jobs and advances after King Riku’s failed attempt to repay the ten-billion-Berry debt.
• Doflamingo’s tax-free businesses drove local competitors out of business, leaving King Riku with little power beyond the palace.
• The arena removed restrictions on sharp weapons and killing, but Kyros still defeated every challenger, including nearly all the Donquixote Family’s officers.

Mousse traced Kyros’s conflicted beliefs to Dressrosa’s long history of suppressing violence and its recent swing toward glorifying it, then proposed taking Kyros away so he could see the wider world. He planned to use a meeting with Kyros to send him far from Dressrosa, leaving him to find his own way home.

• Mousse realized Kyros’s distress stemmed from being condemned for killing a murderous noble and from the conflict between Dressrosa’s old pacifism and its new worship of violence.
• Mousse concluded that the Riku Royal Family had spent centuries encouraging fear of violence to keep the people passive and preserve its rule.
• Mousse explained to Charlotte Amande that Kyros needed distance and exposure to other societies to form his own beliefs.
• Mousse planned to surprise Kyros with Soul Capture, put him in the Book World, and have Amon carry him far away before leaving him to return to Dressrosa on his own.
• The author announced that the novel would return to one update per day after a failed attempt at daily full attendance and ongoing writing difficulties.

Mousse sent Kyros to the Hundred Thousand Mountains and left Charlotte Amande to accompany him, helping her become an unprotected pirate in the Four Blues. After visiting Li Dayong, Mousse learned that he was delaying rebellion to build support and prepare to replace the Flower Kingdom’s hereditary monarchy.

• Mousse sent Kyros to the Hundred Thousand Mountains, where the Flower People’s revolt and Li Dayong’s leadership challenged the values Kyros had learned in Dressrosa.
• Charlotte Amande chose to stay with Kyros, and Mousse advised her to master her strength and use it without needless cruelty.
• Mousse framed Charlotte Amande and Kyros’s journey as an elopement, hoping their relationship would develop into romantic love.
• Mousse visited Li Dayong, whose Swamp-Swamp Fruit and Observation Haki had grown powerful, and saw how he had transformed the Hundred Thousand Mountains into fertile farmland.
• Li Dayong explained that he was cultivating talent and building a core team before overthrowing the Long Hand Royal Family, because he wanted to replace hereditary rule and slow the Flower Kingdom’s historical cycle.

Mousse tracked down Capone Bege to claim the Castle-Castle Fruit, but his attempt to capture Bege with the Book World's Soul Capture failed. After overpowering and incapacitating him, Mousse took Bege away and killed him and the gang members hidden inside him.

• Mousse located Capone Bege, but the Book World's Soul Capture could not affect him, possibly because the Castle-Castle Fruit was also a spatial ability.
• Capone Bege attacked Mousse with a Gatling Gun and tried to release the men inside his castle, but Mousse blocked the bullets and froze the castle gates and cannons.
• Capone Bege surrendered, but Mousse shot him in the thigh with a Seastone-tipped bullet, weakening him and nullifying his Devil Fruit defenses.
• Mousse used Formless to carry Bege to the shore, then built an underwater ice chamber and killed Bege along with the several hundred subordinates inside him.

Mousse helped Charlotte Mont-d'Or develop the Castle-Castle Fruit into a modern sea fortress and equipped it with powerful weapons. The fortress’s defenses and armament promised enormous strength, but a capable, well-trained garrison would take years to assemble.

• Mousse stored the reborn Castle-Castle Fruit, left the Book World with Amon, and reflected on Charlotte Chiffon’s choices during the failed assassination plot.
• Mousse advised Charlotte Mont-d'Or to develop a mobile sea-fortress form and redesign his castle with reinforced concrete and improved firing positions.
• Mousse supplied Charlotte Mont-d'Or with modern firearms and artillery, including anti-materiel rifles and autocannons for his garrison.
• Mousse concluded that the fortress’s greatest limitation was the lack of trained personnel, since Totto Land’s educated children and potential clones would need years before they could fight.

Mousse investigated ways to make the Charlotte Family larger and stronger, but his research into the Giant Medicine led him to suspect that it harmed users’ souls and lifespans. He stopped that research and shifted attention to Island Clouds, which might provide a safer source of PYROBROIN.

• Vegapunk encouraged Mousse to keep improving the Giant Medicine, while Mousse also tried to concentrate PYROBROIN from seawater with Charlotte Smoothie's ability and failed.
• Mousse gathered Island Clouds and discovered that their PYROBROIN had lost its usual volatility, leading him to theorize that supernatural forces governed the substance.
• Mousse connected the Giant Medicine’s effects to changes in soul intensity and lifespan, and compared its mechanism with Mighty Water.
• Mousse halted Giant Medicine research to protect his family, and Vegapunk approved the decision and redirected their work toward Island Clouds.
• Mousse and Vegapunk planned to remove harmful components from Island Clouds and investigate how clouds could help concentrate seawater PYROBROIN.

At thirteen, Mousse helped Praline advance her training while developing a transparent air-filtering helmet that enabled safer underwater practice. He learned Fisher Tiger had been sold to a Celestial Dragon but chose to wait before attempting a rescue, and Totto Land celebrated Baron Tamago awakening his Devil Fruit ability.

• Huo Lisha brought Panda and its mate to Totto Land, where the pandas sparked a craze among the citizens and especially Praline.
• Mousse encouraged Praline to balance her studies and training with time around the pandas, and she surpassed 3,000 Doriki before turning thirteen.
• Mousse learned from Stussy that Fisher Tiger had been sold to a Celestial Dragon, but he asked Stussy to watch over him while he waited for a safer chance to rescue him.
• Mousse invented a transparent air-filtering helmet that supported underwater breathing and training, allowing Praline to begin practicing Fish-Man Karate and Fish-Man Jiu-Jitsu in the water.
• Baron Tamago awakened his Egg-Egg Fruit ability, becoming the first to reach that milestone ahead of his counterpart in the original timeline.

Baron Tamago’s awakened Egg-Egg Fruit greatly improved his transformations and fighting ability, and he sent Charlotte Smoothie to study kicking techniques with his former master. The visit ended in violence when the master tried to kill Smoothie and Mousse revealed that the old man was her father, prompting Smoothie to leave and vow to become a famous Great Pirate.

• Baron Tamago’s awakened Egg-Egg Fruit strengthened his transformed forms, shortened his vulnerable egg-yolk period, extended his transformations, and allowed him to fly.
• Baron Tamago sent Charlotte Smoothie and Mousse to the West Blue so Smoothie could train with his former master.
• Baron Tamago’s master attacked Smoothie and Mousse, but Mousse defeated him and learned from his soul that he was Smoothie’s father.
• Mousse explained that the old man resented Charlotte Linlin and the circumstances of his marriage, and he still loathed Smoothie after learning she was his daughter.
• Smoothie left with Mousse, blamed Baron Tamago for the ordeal, and vowed to become a renowned Great Pirate.

After Doflamingo seized Dressrosa’s throne, Charlotte Mousse exploited his guilt and the Charlotte Family’s influence to obtain the Art Fruit. Mousse gave it to his sister Charlotte Galette, whose appearance and aura transformed after she ate it.

• Doflamingo ousted King Riku, forced Violet into the Donquixote Family, and kept King Riku and Princess Scarlett alive as hostages.
• Charlotte Mousse read about Dressrosa’s peaceful transfer of power and decided to extort Doflamingo while congratulating him on becoming king.
• Doflamingo gave Mousse the Art Fruit, which he had bought for Jola, as compensation for breaking his promise to prioritize his own people for good Devil Fruits.
• Mousse chose Charlotte Galette to eat the Art Fruit because her existing Butter-Butter Fruit ability was mediocre and she had strong artistic refinement.
• Charlotte Galette ate the Art Fruit, and Mousse saw her aura and appearance transform.

After studying King’s genetic sample, Mousse and Vegapunk discovered why Lunarians could survive anywhere but concluded that the species could not be saved through cloning or crossbreeding. Their findings inspired Vegapunk to pursue mass-produced environmental energy conversion, but he wanted World Government support, while Mousse doubted the Government would cooperate; Mousse eventually agreed to let Vegapunk try.

• Mousse’s failed attempts to clone King led him to bring Vegapunk into the research.
• Vegapunk found that Lunarians absorbed energy from their surroundings, but their biology made reproduction with other races and viable clones effectively impossible.
• The Lunarian research inspired Vegapunk to consider developing mass-producible devices that drew energy directly from the environment.
• Vegapunk realized that Totto Land lacked the resources to advance the project quickly and proposed seeking investors and scientists, starting with the World Government.
• Mousse argued that the World Government would use the technology to preserve its rule and could not trust Totto Land, but Vegapunk insisted he had no time to wait.
• Mousse stopped trying to dissuade Vegapunk and agreed to let him attempt to secure cooperation.

After the World Government rejected Mousse’s proposal, he told Vegapunk that platinum lead caused Flevance’s White Rot Disease and offered to remove the poison. Vegapunk helped Mousse gain invisibility, and the Five Elders debated cooperating with Totto Land to save Flevance and preserve its revenue.

• The Five Elders rejected Mousse’s proposal, while Vegapunk accelerated clone cultivation in hopes of strengthening trust between Totto Land and the World Government.
• Mousse explained that platinum lead poisoning caused White Rot Disease, and Vegapunk realized Flevance faced disaster.
• Mousse said he could purge platinum lead from patients and their environment, prompting Vegapunk to see a chance to save Flevance and improve relations with Totto Land.
• Vegapunk implanted the Germa 66 Cyborgs’ invisibility ability in Mousse, who found he could hide Amon as well.
• Mousse and Amon spent several days in Flevance undetected before Totto Land informed the World Government.
• The Five Elders debated Flevance’s platinum lead revenue, the possibility of working with Totto Land, and whether to suspend the plan to destroy the kingdom.

Mousse negotiated with the World Government over the Flevance crisis while secretly ensuring the truth about his role would spread. As he treated the poisoned residents, his investigation uncovered how Platinum Lead caused the illness and revealed a possible way to make Giant Medicine more cheaply.

• Mousse accepted the World Government’s demand to take credit for the response, while seeking enough time to treat Flevance’s residents and planning to spread the truth through Director Trafalgar.
• Mousse met Trafalgar Law and introduced himself, while Law’s family grew more convinced of Totto Land’s power.
• Mousse examined the extracted Platinum Lead dust and discovered that cells could engulf the particles, leading him to consider a cheaper method of making Giant Medicine.
• Mousse explained that the residents’ use of Platinum Lead in paints and ceramics had exposed them to the poison, and that basic safety measures could have prevented much of the disaster.
• Doctor Trafalgar believed Mousse’s account of the World Government and royal family’s profiteering, and his words began spreading through Flevance.

Mousse revealed that his aid to Flevance brought him a fortune by having Xuanhuang extract the Platinum Lead pollution, while also securing ties with the Trafalgar family. He planned to keep the Platinum Lead as a strategic resource and recognized Trafalgar Law as a remarkably gifted future surgeon.

• Mousse explained that the World Government and the Flevance royal family each promised him 5 billion Berries for saving the kingdom and concealing the truth.
• Xuanhuang removed the pollution from Flevance and converted it into refined Platinum Lead powder worth an estimated 200 billion Berries.
• Mousse decided not to sell the Platinum Lead immediately because it was a valuable material for ammunition, science, and his family’s firearms businesses.
• Mousse considered buying more Platinum Lead while its price was temporarily low and noted that he could store it for centuries.
• Mousse judged ten-year-old Trafalgar Law to be an exceptional surgeon with outstanding intellect, vitality, and precise hands, and considered him more trustworthy than Hogback.

Mousse left Flevance after inviting Trafalgar Law to join his future crew once Law was older, then traveled to the North Blue to meet Vinsmoke Judge and recruit Germa 66. Judge welcomed him but refused the offer, saying his children had not grown up yet.

• Doctor Trafalgar asked Mousse to wait a few years before taking the ten-year-old Trafalgar Law, and Mousse agreed while inviting Law to become his future ship's doctor.
• Mousse left Flevance and headed for the North Blue after learning Germa 66 was still there.
• Mousse landed on a Germa 66 snail ship and demanded to meet Vinsmoke Judge.
• Judge assumed Vegapunk had joined the BIG Pirates after Mousse mentioned Teacher Beck, and he recognized Mousse's reputation and scientific achievement.
• Judge gave Mousse a warm welcome but firmly refused his recruitment offer, citing that his children were still too young.
