Chapter Summaries

Mousse helped Charlotte Linlin create Athena, a powerful ice Homie who could fuse with Prometheus to unleash a devastating attack. Their test showed that the fusion attack could burn through steel even when Charlotte Linlin reinforced it with her strongest Armament Haki, leaving Mousse with a clearer measure of its danger.

• Athena grew stronger than Prometheus and froze the sea around the island, impressing the family with her immense ice power.
• Charlotte Linlin named the new Homie Athena and praised Mousse for creating her.
• Mousse proposed testing Athena and Prometheus's fusion attack against Charlotte Linlin's Armament Haki using a giant sword.
• The fused Homies burned through the Haki-protected half of the sword, vaporizing most of its steel.
• Mousse had them test the other half with fire alone and found that it only partially melted.

Mousse assessed how Athena’s birth had greatly increased Charlotte Linlin’s combat power, while deciding not to tell her that she might be underestimating her own strength. The chapter ended with Mousse learning that Charlotte Amande had lost a duel to Kyros in Dressrosa and was training furiously afterward.

• Mousse evaluated Athena’s oxygen-assisted attacks, freezing ability, and stamina recovery, concluding that Athena had given Charlotte Linlin powerful new advantages.
• Mousse compared Charlotte Linlin’s ultimate moves and combat abilities, judging that she could defeat three of her former selves without taking damage.
• Mousse detected that Charlotte Linlin’s Haki limit remained below 1.8 and wondered whether she understood how powerful she had become, but chose not to tell her so she would keep training.
• Charlotte Linlin continued training, and her children trained hard alongside her; Charlotte Amande fought her siblings with unusual intensity after returning from Dressrosa.
• Mousse asked Charlotte Custard why Amande was so angry, and Custard explained that Amande had challenged Kyros to a duel before leaving Dressrosa and had lost.

Mousse learned that Kyros had decisively defeated Charlotte Amande by resisting her Time Sword Technique, while Charlotte Custard saw the fight as a benchmark for challenging her someday. The Charlotte siblings continued developing the King's Fist, with Katakuri mastering it quickly and Oven turning it into a repeatable ultimate attack through Overheat.

• Mousse learned that Kyros had disarmed Charlotte Amande after her Time Sword Technique failed to overcome his superior Observation Haki and stamina.
• Charlotte Custard decided he might one day defeat Third Sister Amande by improving his Observation Haki and combining swordsmanship with other weapons and fighting styles.
• Katakuri gained a preliminary grasp of the King's Fist soon after recovering, then mastered Five Apples by the time Oven mastered Three Apples.
• Oven's Overheat greatly accelerated his Haki recovery, letting him prepare Three Apples in under ten seconds and use the King's Fist repeatedly.

Charlotte Linlin trained Katakuri by forcing him to evade her attacks, accelerating his Observation Haki growth while Mousse improved his own training routine. After seeing Smoothie grow into a giant with her Devil Fruit, Mousse realized how powerful she might become if she developed it fully.

• Charlotte Linlin stopped focusing on King's Fist training and began sparring with Katakuri instead.
• At Mousse's suggestion, Linlin used Prometheus to heat Katakuri's mochi and made him evade her attacks without relying on hardened mochi, rapidly improving his Observation Haki.
• Katakuri tried to add Conqueror's Haki to his attacks so he could counterattack Linlin, but found it difficult.
• Mousse used short, intense weighted workouts and spent time studying, researching, and guiding Smoothie's Devil Fruit training.
• After Smoothie showed Mousse that she could absorb water and grow more than ten meters tall, he realized her Squeeze-Squeeze Fruit might let her become an enormous, powerful fighter.

Mousse helped Charlotte Smoothie rethink how to use the Squeeze-Squeeze Fruit, improving her fighting style despite her preference for swordsmanship. Smoothie began training to shorten her legs for mobility and learned to enlarge only parts of her body, substantially increasing her destructive power.

• Mousse explained that Smoothie's swordsmanship poorly matched the Squeeze-Squeeze Fruit and suggested she train leg techniques, but Smoothie refused because she thought swords were cooler.
• Mousse discovered Smoothie could shorten her legs without weakening them and advised her to practice Soru and Geppo in a short, thick-legged form.
• Smoothie reluctantly kept her legs shortened to train for flight, and Mousse later made her interested by teaching her to alter her appearance for pranks.
• Mousse prioritized the fruit's ability to absorb water and enlarge the body, showing Smoothie how to enlarge specific body parts instead of her whole body.
• By using localized enlargement, Smoothie doubled her destructive power, reduced her target size, and placed less strain on her ship.

Mousse helped Charlotte Smoothie develop her Squeeze-Squeeze Fruit and devised a way for her to build up excess Armament Haki in giant form before unleashing it in a concentrated attack. Smoothie began practicing the technique, which Mousse suspected might explain the power of Kaido’s strongest Thunder Bagua strikes.

• Mousse suggested Smoothie use her water-spraying ability to improve the range and power of future sword slashes, and Smoothie eagerly practiced spraying water.
• Smoothie became interested in learning Tempest Kick and Shigan after discovering she could combine them with her water ability.
• Mousse used his Observation Haki to notice that Smoothie’s giant form increased her Haki capacity, then coached her to refill that capacity and gain a preliminary grasp of Armament Haki.
• Mousse proposed that Smoothie build up excess Haki in giant form, shrink back to normal, and release the overflow in a powerful strike; Smoothie began practicing the cycle.
• Mousse connected Smoothie’s proposed technique to Kaido’s Thunder Bagua attacks, speculating that Kaido had built up Haki in dragon form before striking in human form.

Mousse reflected on Smoothie’s potential and focused on helping his younger sister Praline develop her exceptional abilities through disciplined training and study. Praline’s future looked promising, though Mousse knew the dangers ahead made it essential for both of them to grow stronger.

• Mousse realized that Smoothie’s training could help her become a formidable one-on-one fighter despite her lazy reputation.
• Mousse compared Praline’s extraordinary Fish-Man talents with her poor performance in the original timeline and resolved to help her reach her potential.
• Mousse kept Praline to a demanding, optimized training regimen, even when it made her cry.
• Mousse added cultural studies to Praline’s routine after discovering that education could raise a person’s Haki limit.
• Mousse decided Praline could learn Soru and Geppo for now, since Totto Land lacked a suitable Fish-Man martial arts teacher.

Mousse struggled to find training methods that could keep up with Praline’s growing strength, while reflecting on her and Charlotte Galette’s different abilities. After discovering that Charlotte Galette’s physical strength had surged when she ate her Devil Fruit, Mousse investigated whether Devil Fruits directly improved the body and began questioning what the Book-Book Fruit had changed in him.

• Mousse considered gold-filled weights and artificial low-pressure training for Praline, but found no lasting solution comparable to a Gravity Room.
• Mousse reflected that Praline’s Fish-Man traits gave her strength and sharp teeth, while Charlotte Galette lacked combat talent and had little interest in training.
• Mousse recalled that Charlotte Galette’s strength more than doubled when she ate her Devil Fruit, overtaking his gains from nearly two years of training.
• Mousse questioned Devil Fruit users across Totto Land, and Smoothie, Perospero, and Baron Tamago reported signs of increased physical ability.
• Mousse tested a Zoan-type Devil Fruit on condemned criminals and found that it increased vitality, with stronger subjects gaining more in absolute terms but less proportionally.
• Mousse inferred that Devil Fruits might provide a physique-dependent boost and wondered whether the Book-Book Fruit had instead strengthened his soul.

Mousse used Devil Fruit experiments to investigate how Fruits affected strength, vitality, and the soul, and his discoveries clarified why people could sometimes survive eating multiple Fruits. He concluded that Devil Fruits offered a way for the less talented to close the gap with the naturally gifted, leaving him more confident about his future.

• Mousse realized the Mongoose-Mongoose Fruit: Kangaroo Form suited the King's Fist and recommended it to the king of Prodence Kingdom, who ate it and paid him extra.
• Charlotte Linlin increased Mousse's influence over family finances after his successful sale, and he used it to buy inexpensive Devil Fruits for experiments.
• Mousse found that Devil Fruits of the same category could provide different boosts and that eating multiple Fruits could be fatal depending on their order and strength.
• Mousse concluded that an awakened Devil Fruit could not be displaced by another, explaining why Kaido would survive being force-fed a Fruit.
• Mousse confirmed that Paramecia Fruits increased soul strength and inferred that his Book-Book Fruit enhanced only the soul, then grew more confident that Devil Fruits could help the less talented catch up.

Mousse continued investigating how Devil Fruit development related to physical ability and soul strength, concluding that study could improve some users’ abilities. He planned different training paths for Baron Tamago, Charlotte Brulee, and Charlotte Mont-d'Or.

• Mousse found that his sister’s Devil Fruit-enhanced physical qualities did not translate into better training results, while an older, untrained test subject’s vitality and mental strength kept increasing.
• Mousse concluded that Devil Fruit boosts fluctuated with development, which depended on a user’s basic abilities and soul strength; he reasoned that studying and reading could strengthen the soul.
• Mousse decided not to urge all his siblings to study, but advised Baron Tamago to focus on physical training because his Egg-Egg Fruit development appeared tied to his constitution.
• Baron Tamago rapidly developed his Egg-Egg Fruit, shortened its incubation period, and awakened Armament Haki and Observation Haki.
• Mousse urged Charlotte Brulee and Charlotte Mont-d'Or to study, believing their Devil Fruit abilities and ordinary physiques made learning especially valuable.

Mousse considered how the Charlotte Family could profit from the Devil Fruits they had bought and arranged for Charlotte Comte, Charlotte Cantz, Charlotte Cavalier, and Charlotte Gala to use the Rumble-Rumble Fruit’s fusion power. News that the Marines had apparently killed Silvers Rayleigh unsettled Mousse, who suspected Rayleigh might have escaped underwater and been rescued by Hachi.

• Mousse planned to resell the low-priced Zoan Fruits to Kaido and considered the Rumble-Rumble Fruit’s potential for the Charlotte Family.
• Charlotte Amande rejected the Rumble-Rumble Fruit because she feared its fusion power would hinder her swordsmanship, so Charlotte Linlin chose Charlotte Opera’s four younger brothers instead.
• Charlotte Comte, Charlotte Cantz, Charlotte Cavalier, and Charlotte Gala became powerful fighters after gaining the ability to fuse, though Mousse regretted that Charlotte Opera could not join them because he had already eaten a Devil Fruit.
• Perospero told Mousse that Marine Admiral Sengoku had knocked Silvers Rayleigh into the sea and that patrols had failed to find him, leading the Marines to declare him dead.
• Mousse questioned whether Rayleigh had died near Marine Branch G1 and suspected that Hachi might have rescued him near Fish-Man Island.

After Roger surrendered and the Navy announced his execution in Loguetown, Mousse recognized that its forces would be divided and planned to exploit the opening by attacking Branch G1. Katakuri agreed that striking first was the best way to protect the Charlotte Family, whose Linlin had grown dramatically stronger.

• Mousse dismissed the need to investigate whether Rayleigh was alive and considered Sengoku’s strength after learning he had driven Rayleigh into a desperate situation.
• The BIG Pirates learned that Roger had surrendered, and Mousse understood that the Navy could now focus on retaliating against the Charlotte Family.
• Mousse concluded that the Navy’s forces could not quickly reinforce each other during Roger’s execution and identified an opportunity to attack Marine bases in the New World.
• Mousse proposed destroying Branch G1 to isolate the Navy’s other New World bases and delay its ability to send fleets into the region.
• Katakuri accepted the plan and trusted Linlin’s strength after seeing her Doriki approach 40,000 and her combat skills improve through training.

Charlotte Linlin greatly increased her combat power by mastering Tekkai, localized hardening, Tempest Kick, and stronger Conqueror's Haki. As the family debated attacking Marine Branch G1 during a public execution, Mousse proposed waiting for the broadcast to confirm it was real and relying on Brulee's Mirror World to retreat, then introduced his new gyroscope invention.

• Charlotte Linlin mastered Tekkai and learned localized hardening and Tempest Kick, boosting her defense, attacks, and usefulness in building Totto Land.
• Katakuri assessed Charlotte Linlin's strengthened Haki and concluded that few Marines besides top Admirals could challenge her.
• Perospero warned that the Marines might reinforce Branch G1 or use the public execution as a trap, while Mousse agreed Sengoku might be there but welcomed the chance to defeat him.
• Mousse proposed waiting until the execution broadcast ended before attacking Branch G1 and pointed to Brulee's Mirror World as an escape route.
• Mousse prepared to explain his plan and introduced his new invention, the gyroscope.

Mousse planned a secret attack on Marine Branch G1, using Charlotte Brulee’s Mirror World as an escape route and the execution of Roger as cover. The BIG Pirates spent the next month preparing while keeping the plan hidden from everyone but four people.

• Perospero recognized the value of Mousse’s gyroscope, which could guide ships without interference from the Grand Line’s magnetic fields.
• Mousse used the gyroscope, timing and drawing devices, and Big Head to map the sea around Totto Land, discovering that Marine Branch G1 was less than nine hundred kilometers away.
• Mousse proposed taking Charlotte Linlin and Katakuri to Marine Branch G1 on a warship, with Charlotte Brulee waiting near a mirror so they could escape through the Mirror World.
• Perospero questioned whether Charlotte Linlin and Katakuri could overcome the fortress, but Mousse and Charlotte Linlin were confident they could attack from beyond the cannons’ range.
• Mousse stopped Charlotte Linlin from contacting Whitebeard, warning that the World Government might learn of the plan, and suggested monitoring Whitebeard through their own informants.
• The BIG Pirates prepared a small warship and a custom bulletproof mirror over the next month, while Mousse, Perospero, Katakuri, and Charlotte Linlin kept the plan secret.

Mousse learned which Marines would be stationed at Loguetown and discussed the forces left behind with Stussy, but their call ended when someone approached her. Stussy survived the encounter by presenting Mousse’s analysis as her own, earning the old CP0 leader’s approval.

• Stussy told Mousse that Kong, Garp, and Borsalino would accompany Roger, while Sengoku moved to Branch G1 and Tsuru and Dill remained at Marineford.
• Stussy abruptly ended the call when someone arrived, and a shriveled old man confronted her for contacting pirates.
• The old man threatened Stussy with crippling Armament Haki, but she claimed she had contacted pirates for CP0 and the World Government’s benefit.
• Stussy repeated Mousse’s analysis of CP0 and its masters, impressing the old man with her insight and initiative.
• The old man withdrew his Haki and told Stussy that CP0 needed talents like her, while she realized Mousse had supplied the words that saved her.

The scrawny old man suspected Stussy had Witch Bloodline, giving her more time to develop her strength and a path toward CP0 leadership. With one week remaining until Roger’s execution, Mousse’s plan set two BIG Pirates ships sailing toward their roles in the operation against Marine Branch G1.

• The scrawny old man explained that witches could live for two hundred years and judged that Stussy’s vitality meant she might have Witch Bloodline and untapped potential.
• The scrawny old man planned to train Stussy, promote her to Queen of the Pleasure District, and prepare her eventual rise into CP0 leadership.
• Stussy feared Mousse’s intelligence and suspected he might one day threaten the Celestial Dragons, but she chose not to report him because doing so would cost her future and life.
• With one week left until Roger’s execution, two BIG Pirates ships left Whole Cake Island to carry out Mousse’s plan.
• Mousse assigned Perospero’s new Homie flagship to anchor the Mirror World operation, while Charlotte Linlin, Katakuri, Daifuku, and Mousse took the ship tasked with attacking Marine Branch G1.
• Mousse planned to rely on his Homie, Big Head, to deter Sea Kings, allowing the attack ship to be abandoned after the mission without wasting a Homie ship’s soul.

Mousse brought Charlotte Linlin and her sons to Marine Branch G1, where they used Zeus’s clouds to withstand Borsalino’s probing attacks while preparing a possible King’s Fist ambush. After Borsalino reported that Charlotte Linlin was present, Sengoku chose to avoid a confrontation until the Marines could reunite their forces.

• Mousse’s group reached the waters outside Branch G1 after a six-day voyage, and Charlotte Linlin began warming up for King’s Fist.
• Sengoku summoned Borsalino to scout the BIG Pirates because he would not risk sending out a warship without knowing the enemy’s strength.
• Borsalino attacked from a distance, but Zeus’s clouds blunted his lasers and forced him to retreat without approaching the ship.
• Mousse had Katakuri build a hardened mochi wall to hide the gathering Armament Haki, but Borsalino withdrew before Katakuri could launch King’s Fist.
• Borsalino reported Charlotte Linlin’s presence to Sengoku, who decided to wait until the Fleet Admiral and Garp returned before concentrating Marine forces against the BIG Pirates.

Borsalino persuaded Sengoku to seek help from the World Government after Charlotte Linlin attacked the Red Line. A Five Elder and the gaunt CP0 leader joined the Marines at G1, where Gol D. Roger’s execution broadcast abruptly changed the three powerhouses’ expressions.

• Borsalino proposed asking the World Government for reinforcements, and Sengoku agreed to contact the Five Elders.
• The Five Elders decided to send the bald swordsman and asked the gaunt CP0 leader to join the fight against Charlotte Linlin.
• The gaunt old man agreed to help, left Stussy, and flew to Marine Branch G1.
• The gaunt old man arrived at G1 in a controlled torrent of black mud, then returned to human form without damaging the rooftop.
• General Commander Dill arrived at G1, where a broadcast of Gol D. Roger’s execution played and changed the expressions of Sengoku, the gaunt old man, and Dill.

Mousse directed Charlotte Linlin’s attack against the three approaching Marine powerhouses, exploiting their ship’s slow maneuvering and an opponent’s attempt to evade. The chapter ended as Linlin launched her King’s Fist toward Sengoku.

• Sengoku blamed Roger’s public execution on the Five Elders and Kong, while the three Marine powerhouses remained confident they could win.
• Mousse used Observation Haki to sense three powerful enemies approaching and judged that Linlin’s partly charged attack would need to be combined with King's Spear.
• Mousse calculated the attack’s timing and range, then stopped Linlin when he sensed one opponent jump from the warship to evade it.
• Mousse ordered Linlin to fire at a revised rotation speed, and she unleashed King’s Fist toward Sengoku while the other two Marines remained aboard.

Mousse’s assault devastated Marine Branch G1 and sent Sengoku crashing into the Red Line, while the World Government’s forces suffered catastrophic losses. Charlotte Linlin and her Homies then pursued the surviving old man, setting him up for her Elbaf Spear: King’s Spear.

• Sengoku transformed into his Great Buddha Form and tried to stop Mousse’s Haki-laden punch, but the blow overwhelmed him and hurled him into the Red Line.
• The punch carved a massive crater into the Red Line, shook Mary Geoise, and left Im alarmed and asking if it was Pluton.
• The shockwave and falling debris destroyed much of Marine Branch G1, sank or crippled most of its warships, and killed many Marines.
• Dill was torn apart by the blast, while the shriveled old man escaped the initial attack by using Geppo.
• Prometheus and Athena merged, used rocket-like propulsion to catch the old man, and attacked him with freezing air and Oxygen Welding.
• As the old man struggled to evade them, Charlotte Linlin aimed her Elbaf Spear: King’s Spear at him.
