Recaps

Mousse examined the family’s new bounties and worried that the World Government’s hostility toward them had reached a dangerous level. As the Queen Mama Chanter sailed past Dressrosa, Betta fish attacked the ship, and Mousse realized they had an ability aboard that could counter the creatures.

• Mousse saw that Katakuri’s bounty had risen to 2 billion Berries and wondered if Kizaru had been killed.
• Mousse noted that Oven’s bounty had climbed to 690 million Berries, while Cracker’s comparatively modest increase kept his strength concealed.
• The Queen Mama Chanter came under attack from a large school of Betta fish near Dressrosa, alarming Amande and Castard.
• Mousse explained that Betta fish were fearless, dangerous Sea Beasts and recognized that their ship had an ability suited to defeating them.

Charlotte Oven used his enhanced Hot Sea Hot Spring to boil the surrounding sea and kill the Betta fish attacking the ship. Mousse learned that Overheat amplified Oven’s heating ability by more than ten times, revealing a major boost to his combat potential.

• Mousse asked for a rope, and Brulee passed one to Charlotte Oven so he could reach the sea.
• Oven tied the rope to the mast, lowered himself into the water, and activated Hot Sea Hot Spring through his waterproof boots.
• Oven’s heat boiled the sea, forcing the Betta fish to leap out before they died floating on the surface.
• Mousse asked Oven about his strengthened ability and learned that Overheat boosted his heating power by more than ten times.
• Mousse realized Oven could combine his amplified heat with his powerful attacks without straining his body.

Mousse offered King Riku a deal: if Dressrosa helped Charlotte Oven’s group secure an introduction to King Elizabello, they would reopen transportation between Dressrosa Island and Green Bit Island. King Riku was tempted by the promise of relief from the Betta fish, and Charlotte Oven confirmed that Mousse spoke for their family.

• Mousse congratulated Charlotte Oven on his new attack and suggested visiting Dressrosa before continuing their journey.
• The Queen Mama Chanter entered Dressrosa’s port, and the frightened officials summoned King Riku Dold III.
• King Riku welcomed Charlotte Oven’s party and considered refusing their request to have him approach King Elizabello in person.
• Mousse offered to restore transportation between Dressrosa Island and Green Bit Island as compensation for King Riku’s help.
• King Riku reconsidered when he realized the offer could solve Dressrosa’s long-standing Betta fish crisis.
• Charlotte Oven told King Riku that Mousse was his family’s strategist and that Mousse’s opinion was his own.

Mousse and the BIG Pirates demonstrated that Charlotte Oven could eliminate Dressrosa’s Betta fish menace, but Oven continued heating the water after the fish had died. Mousse realized Oven was pushing himself through a breakthrough, and Cracker stopped King Riku from interrupting him.

• Mousse offered to have the BIG Pirates pay Dressrosa’s reward in advance, and King Riku agreed to let them deal with the Betta fish.
• Charlotte Amande killed Betta fish that leaped onto shore as the group approached the broken bridge and its fish-infested strait.
• Charlotte Oven activated Hot Sea Hot Spring in his Overheat state, scalding King Riku and his attendants while killing Betta fish in the water.
• Oven increased his power and plunged his hands into the water, alarming King Riku, who rushed forward and begged him to stop.
• Mousse suspected Oven was breaking through and ordered Cracker to restrain King Riku, who realized Cracker could easily overpower him.

Charlotte Oven’s Overheat caused a winter deluge in Dressrosa, and Mousse confirmed that Oven had awakened the Heat-Heat Fruit. After the storm subsided, King Riku joined Mousse’s party aboard the Queen Mama Chanter, which sailed for the Pudding Kingdom.

• Charlotte Oven’s Overheat brought torrential rain and lightning to Dressrosa, and Zeus helped weaken the storm before Oven stopped using his power.
• Oven’s hunger revealed the stamina cost of Overheat, so Cracker made biscuits for him to replenish his energy.
• Mousse confirmed that Oven had awakened the Heat-Heat Fruit, allowing him to project heat remotely and conduct it through air and other materials.
• Mousse considered the danger Oven’s awakened ability posed to opponents, especially Fish-Men underwater.
• King Riku arranged disaster relief and boarded the Queen Mama Chanter with Mousse’s group to travel to the Pudding Kingdom.

Mousse and King Riku tried to persuade Elizabello II to reveal the secret of the King's Fist, but the young king refused until Riku explained the BIG Pirates’ power. A challenge then began, with Cracker’s Biscuit Soldier chosen to test the technique instead of Oven.

• Elizabello II refused to reveal the King's Fist, and Mousse mocked the technique’s long preparation time and limited usefulness.
• King Riku restrained the furious Elizabello II and told him how Oven had boiled the sea, convincing him that the BIG Pirates posed a serious threat.
• Mousse belittled the King's Fist to provoke Elizabello II, and Oven stepped forward to take the punch.
• Mousse persuaded Oven to let Cracker’s Biscuit Soldier test the technique, and Cracker created one for the challenge.
• Elizabello II agreed to try a reduced-power version of the King's Fist against the Biscuit Soldier after Cracker taunted him and King Riku urged caution.

Elizabello II tested the King's Fist against Cracker’s Biscuit Soldier, but the attack barely cracked its shield and left the king badly injured. Mousse concluded the technique relied on Armament Haki rather than a hidden bodily training method, while Charlotte Kastard reacted with a sly smile.

• Elizabello II led Mousse and the BIG Pirates to the mountain pass, where Flanders Kingdom’s army backed down after seeing their flag.
• After an hour of warm-up, Elizabello II struck Cracker’s reinforced Biscuit Soldier with the King's Fist, but the shield barely cracked and the rebound sent him flying.
• Mousse and the others found Elizabello II badly injured but expected him to recover after several days of rest.
• Cracker praised the power of the King's Fist, while Mousse explained that it seemed to be a special use of Armament Haki rather than a body-training technique.
• Charlotte Oven accepted that he would need to train through slow effort, and Charlotte Kastard responded with a sly smile.

While the group waited for Elizabello II to recover, Charlotte Custard discovered that Mousse had awakened Observation Haki at five. She learned that his Haki talent was badly limited by his Doriki Value of only 1, leaving him with very little stamina to use it.

• The group stayed in the kingdom while Elizabello II recovered, with King Riku arranging accommodations for them.
• Charlotte Custard invited Mousse to sleep beside her and asked whether he had awakened Observation Haki.
• Mousse admitted that he had awakened Observation Haki a year earlier, and Charlotte Custard was astonished by his early talent.
• Mousse explained that his low physical stamina made his Haki slow to recover and difficult to use for long.
• Charlotte Custard guessed that Mousse's Doriki Value was only 1, and Mousse confirmed it.

Charlotte Custard reassured Mousse about his weak stamina, and he resolved to grow powerful through technology and Homies. The next morning, Elizabello II agreed to reveal the secret of the King's Fist for payment, but Mousse insisted on staying with Charlotte Oven to hear it.

• Charlotte Custard comforted Mousse and told him that Perospero had been physically weak as a child.
• Mousse decided that Big Brother Perospero saw himself in him and strengthened his resolve to become powerful through intelligence, technology, and Homies.
• Mousse woke after ten hours of sleep and found that Elizabello II had recovered enough to walk with a nurse's help.
• Charlotte Oven renewed the demand for the secret of the King's Fist, and Elizabello II agreed to reveal it for 800 million Berries while refusing the BIG Pirates' offer of military protection.
• Elizabello II ordered everyone else to leave, but Mousse insisted that he and Charlotte Oven stay, and the king accepted.

Mousse learned how Charlotte Oven could test the King's Fist and then traveled to Dressrosa to study its ancient books, strengthening his Book-Book Fruit ability. He returned with faster Big Head, but the Book World remained elusive and his stronger Observation Haki still recovered too slowly to use effectively.

• Elizabello II explained that the King's Fist stored flowing Armament Haki outside the body before releasing it in a powerful burst.
• Mousse proposed that Charlotte Oven test the King's Fist's Haki-release technique first, and Oven quickly learned to vent his Haki.
• Oven struggled with the charging technique but found that practicing it rapidly improved his Armament Haki.
• Mousse traveled through the Mirror World to Dressrosa and gained access to its royal library after King Riku had returned.
• Mousse studied and recorded valuable books, strengthening his Book-Book Fruit ability and enabling Big Head to fly at over four hundred kilometers per hour.
• Mousse still could not access the Book World, and his increased Observation Haki remained difficult to use because its recovery speed had not improved.

Mousse decided he needed to travel alone to Ohara before it was destroyed, but worried about gaining his family's permission and protecting himself. Princess Scarlett interrupted his plans and invited him to watch Dressrosa's arena tournament, leaving him interested in attending from the VIP seats.

• King Riku told Mousse that the West Blue held major centers of learning, reminding Mousse to visit Ohara before its books were destroyed.
• Mousse considered traveling alone to Ohara and worried about his family's approval and his ability to stay safe.
• Princess Scarlett slapped Mousse, and he warned her off by smashing the marble floor with his giant stone club.
• Scarlett explained that she had come to invite Mousse to a tournament celebrating the Betta fish's extermination.
• Mousse learned that the tournament offered two hundred million Berries in prizes and realized Scarlett's invitation might be his only way to watch from the VIP seats.

Mousse watched the Dressrosa arena tournament with Princess Scarlett and considered the kingdom’s poverty and the tournament’s rules. While using Observation Haki to assess the contestants, he discovered that his Book-Book Fruit had turned the information he sensed into precise data.

• Princess Scarlett begged Mousse to watch the arena matches, and her guard decided to report their growing closeness to King Riku afterward.
• Mousse observed Dressrosa’s poverty but chose not to intervene, fearing World Government suspicion and believing the Riku royal family was the root of the kingdom’s problems.
• A palace guard explained that the tournament required contestants to have a Doriki Value over 500 and excluded fighters who relied on dangerous special abilities.
• Mousse considered how concealing his own powers and learning about opponents would help him maintain an information advantage.
• Mousse used Observation Haki to estimate the contestants’ strength but struggled to judge those far stronger than himself.
• Mousse’s Observation Haki information began fluctuating and appeared as precise data, leading him to suspect his Book-Book Fruit had caused the change.

Mousse’s anomalous Observation Haki displayed everyone’s Haki reserves, leading him to conclude that Haki existed in all people before awakening and that innate vitality or mental power shaped its type and capacity. He left the arena understanding how to distinguish awakened Haki and still wondering why his own reserves were so vast.

• Mousse saw that ordinary spectators and contestants alike possessed Haki, confirming that Haki existed in people before they awakened it.
• Mousse reasoned that people with greater physical capacity tended to awaken Armament Haki, while those with stronger minds or sensitivity tended to awaken Observation Haki.
• Mousse realized that filling his Haki reserves and training might help him master Armament Haki, but his slow recovery made the process uncertain.
• Mousse noticed that his Haki reserves far exceeded those of everyone in the arena and considered whether his powerful soul explained his exceptional capacity.
• Mousse distinguished awakened Haki by its fluctuating reserves, while spectators’ fixed values indicated their Haki had not awakened.

Mousse realized that his datafied Observation Haki measured vitality rather than Combat Power and began considering how size distorted his estimates. He then spotted Charlotte Castard competing in Dressrosa and grew worried when her formidable opponent drew a katana and charged.

• Mousse watched a giant lose to a smaller swordsman and concluded that Observation Haki’s unusually high readings reflected vitality, not Combat Power.
• After observing more fights, Mousse reasoned that large bodies inflated vitality readings and that he needed enough battle data to develop a Size Correction Factor.
• Mousse recognized his sister Charlotte Castard in the tournament, and Princess Scarlett explained that Castard had come looking for him the previous day.
• Charlotte Castard faced a katana swordsman whose vitality reading exceeded three thousand, and Mousse worried that the closely matched fighters could seriously injure each other.

Mousse watched Charlotte Custard win an arena match and used the fights to reason through Haki expenditure, stamina, and Luffy’s victory over Katakuri. After Custard revealed she had come to Dressrosa and entered the arena, she joined Mousse in the front row.

• Charlotte Custard used her reach and Soru to defeat her opponent with a concealed Shigan after he launched a Flying Slash.
• Mousse applauded Custard and reflected on the advantages of height, reach, and agility.
• After watching several battles, Mousse concluded that fighters who used Haki at full strength could quickly exhaust it, making his large Haki reserves a major advantage.
• Mousse reasoned that Luffy had recovered his stamina and Haki by eating mochi during his fight with Katakuri, and that Katakuri could have won by stalling instead of fighting head-on.
• Mousse recognized Charlotte Custard when she covered his eyes, and she told him she had come to Dressrosa and entered the arena for its prize money.

Mousse learned from Charlotte Castard that his siblings’ allowances were limited and even Charlotte Amande was competing for the tournament’s prize money. He recognized Totto Land’s shortage of cash amid abundant supplies as resembling the Soviet Union’s economy and realized he might be able to improve the situation.

• Charlotte Castard took Mousse onto her lap and explained that her monthly allowance of 300,000 Berries barely covered cosmetics.
• Castard told Mousse that Charlotte Amande had entered the tournament for its 100 million Berries prize, despite being slated to become a minister and island lord.
• Mousse questioned why the family was short on cash despite Totto Land’s plentiful supplies and learned that most funds went toward strengthening the family.
• Mousse compared Totto Land’s economy to the Soviet Union’s, where abundant resources coexisted with shortages of money and goods the country could not produce.
• Mousse concluded that Totto Land’s limited cash income might not be difficult for him to increase.

Mousse considered how Totto Land might profit from export trade, then assessed the strength of the tournament contestants and Charlotte Amande. After discovering Amande’s impressive abilities, he wondered whether the Serpent Head Tribe faced a racial limit on swordsmanship.

• Mousse concluded that Totto Land’s export trade could be lucrative, but war with the Marines made it impractical, and he understood why Charlotte Amande wanted the tournament’s prize money.
• Mousse warned Charlotte Castard that the arena held formidable contestants, including the undefeated Kyros, but Castard remained confident in Amande’s chances.
• Mousse learned that Amande had skipped the preliminaries and estimated her strength at roughly five thousand Doriki, with Haki that ranked among the contestants’ best.
• Mousse connected Amande’s apparent progress plateau with the Serpent Head Tribe’s history of producing many swordsmen but no known Grand Swordmasters, leaving him questioning what limited them.

Mousse learned how swordsmanship ranks were distinguished and realized that Grand Swordmasters combined powerful Observation Haki with Armament Haki. He used his own ability to perceive weaknesses to damage marble with a fruit knife and a tray, naming the ability the Mind's Eye.

• Charlotte Custard told Mousse that swordsmanship ranks were generally based on reputation, but Charlotte Amande explained that swordmasters could cut steel and unleash Flying Slashes.
• Charlotte Amande said Grand Swordmasters could unleash casual, efficient Flying Slashes and perceive the weaknesses of all things, using Observation Haki to find weaknesses and Armament Haki to cut through them.
• Mousse wondered whether his strong Observation Haki could let him perceive weaknesses, and his perception suddenly made weak points in objects clear.
• Mousse used a fruit knife to scratch hard marble, prompting Charlotte Amande to suggest he might have a Sword Heart and Charlotte Custard to praise him.
• Mousse rejected the Sword Heart explanation, poked a hole through the fruit tray with his finger, and named his weakness-perceiving ability the Mind's Eye.

Mousse explored how Observation Haki could reveal weaknesses in people and weapons, while Charlotte Amande continued teaching him about swordsmanship. At the tournament, Charlotte Castard conceded her match against Amande, who then fought a fast and powerful Mink Tribe fighter.

• Mousse reasoned that Observation Haki could help him target weak points in human defenses and named his prospective technique Hokuto Shinken.
• Mousse learned that weapons could contain Armament Haki and wondered what made Black Blades special.
• Charlotte Castard won another match and advanced to the round of sixteen, where she conceded to her sister Charlotte Amande before their fight began.
• Charlotte Amande faced a gorilla Mink Tribe fighter whose supporters filled the stands, and she mocked him as a humanoid beast.
• The Mink charged at Charlotte Amande with tremendous speed, but she dodged and cut him deeply beneath the ribs.

Charlotte Amande used her unusual swordsmanship to slow the gorilla Mink and brutally torture him during the tournament. The gorilla Mink remained conscious and unable to surrender, while the horrified spectators began leaving the arena.

• The gorilla Mink recovered from Amande’s first attack, but she cut him again as his movements slowed.
• Mousse realized Amande’s swordsmanship altered the flow of time, slowing opponents while also affecting her own speed.
• Amande slowly drove her sword between the gorilla Mink’s ribs, leaving him unable to move or speak.
• The gorilla Mink broke down in tears, but the match continued because he could not surrender and had not lost consciousness or left the ring.
• Spectators fled the arena, and Princess Scarlett became frightened and disgusted by Amande.

Mousse watched Kyros interrupt Charlotte Amande’s execution in the arena, then investigated how soul strength might determine Haki and Devil Fruit abilities. Charlotte Linlin summoned Mousse to discuss Garp and Dragon’s sudden departure from Marineford, leaving him to assess whether it was genuine or a cover for an attack.

• Kyros knocked Amande’s sword away from the wounded Gorilla Mink, and the referee declared Amande the winner despite the interruption.
• Amande challenged Kyros after he insulted her, while Castard warned Mousse to stay away from her until the finals.
• Linlin summoned Mousse home, where he measured her and Katakuri’s vitality and Haki and concluded that Haki limits were likely tied to soul strength.
• Mousse wondered whether soul strength could also determine Devil Fruit power, but Linlin told him Garp and Dragon had returned to Marineford and left again the same day.
• Linlin asked Mousse to judge whether Garp and Dragon had truly departed or were preparing a surprise attack, and whether she should recall Oven and the others.

Mousse convinced Charlotte Linlin that Dragon had resigned and Garp had lost his drive after learning the truth about the Faros Incident. He then argued that Oven should return so they could test whether advanced Armament Haki made King's Fist easier to learn, and Oven arrived at Whole Cake Island to report on his training.

• Charlotte Linlin told Mousse that Dragon had resigned and that Garp had returned to sea after meeting with Dragon.
• Mousse concluded that the Faros Incident had driven Dragon to resign and Garp to lose his enthusiasm for Navy work, reassuring Charlotte Linlin about both men.
• Mousse urged Charlotte Linlin not to recall Oven, reasoning that Oven's slow progress with King's Fist might mean Elizabello II had withheld information.
• Mousse suggested that advanced Armament Haki might help someone learn King's Fist faster, so Charlotte Linlin ordered Brulee to bring Oven back.
• Brulee brought Oven from the Pudding Kingdom through the Mirror World, and he began telling Charlotte Linlin about his training.

Charlotte Oven struggled to master the King's Fist, but Charlotte Linlin quickly learned it and demonstrated its devastating power. Katakuri recognized the move’s long preparation time as a major weakness, while Mousse appeared poised to offer another surprise.

• Charlotte Oven said he could not yet retain Armament Haki long enough to complete the King's Fist’s charging stage.
• Katakuri praised Oven’s progress and became interested in how the technique could train Armament Haki.
• Charlotte Linlin accumulated Armament Haki without the warm-up motions, then punched at a cloud but failed to affect it.
• Katakuri suggested the King's Fist lost power over distance, so Charlotte Linlin tried again on a deserted island and made her Armament Haki rotate, destroying a distant cloud.
• Katakuri judged Charlotte Linlin’s punch powerful enough to threaten top fighters but noted that charging it took too long, then looked to Mousse for a possible solution.

Mousse discovered that the King's Fist could be charged rapidly by spending Haki, and Charlotte Linlin used the method to unleash a devastating Elbaf Spear. The attack nearly killed Mousse, but Katakuri shielded him, and the brothers were rescued from the sea.

• Mousse realized that the King's Fist could be charged much faster by converting Haki rapidly, and he tested the method with Charlotte Linlin.
• Charlotte Linlin mistook the technique for the true secret of the Elbaf Spear and instinctively struck Mousse with Ikoku Sovereignty.
• Katakuri grabbed Mousse and shielded him from the attack, and Big Head caught them before they fell into the sea.
• Katakuri reassured Mousse that he was alive, and Mousse complimented his uncovered face before Oven told Katakuri to stop hiding it.

Katakuri survived Charlotte Linlin’s powerful attack while shielding Mousse, and he and Mousse discussed how Armament Haki interacted with his hardened mochi. The family returned to the island, where they discovered that Charlotte Linlin had collapsed into a deep sleep after unleashing her attack.

• Oven confirmed that Katakuri was badly wounded but not in danger, and Katakuri explained that Linlin’s attack had not been fully charged.
• Mousse realized that Armament Haki did not cancel the Mochi Mochi Fruit’s properties, and Katakuri explained how hardened mochi had helped him withstand the blow.
• Mousse understood that Katakuri had risked his life to save him and felt grateful despite joking that his theory had helped Katakuri survive.
• Big Head carried Mousse, Katakuri, and Oven back to the island, where Perospero confirmed they were safe.
• Perospero told Katakuri that Linlin had fallen asleep after her attack, and Mousse suggested waking her while Perospero remained too frightened to approach.
