Chapter Summaries

Sakazuki was ordered to remain on Punk Hazard while Kong arranged another pursuit of Roy and Kaido. Back in Onigashima, Roy gave Dr. Gracia the stolen research equipment, samples, and captured researchers, who agreed to work for him under his promised terms.

• Kong told Sakazuki to assess the damage on Punk Hazard and prepare a report while he consulted the World Government about pursuing Roy and Kaido.
• Three days later, the Ark Maxim returned to Onigashima with stolen equipment, incubation chambers, research materials, and captured scientists.
• Dr. Gracia examined the haul and recognized the incubation chambers as evidence of the World Government's forbidden Lineage Factor experiments.
• Roy offered the captured researchers a choice between joining Dr. Gracia's team or remaining imprisoned to protect the base's secrets.
• Dr. Domir and the other researchers agreed to stay after Roy promised research freedom and protection from Kaido and King.
• Roy assigned the researchers to begin work on bloodline transplantation, with Kaido, Moria, and King set to cooperate.

Roy finished overseeing the research base’s initial setup and arranged an expedition to Raijin Island to train the crews’ strongest members. The two pirate crews prepared to leave in three days, using the Ark Maxim’s appearances to misdirect the Marines while they traveled.

• Roy reassured Kaido that the scientists would remain loyal and explained that freedom and research resources would keep them on the crew’s side.
• Dr. Gracia and the pirates completed the research base’s laboratories, organized Punk Hazard’s seized data, and installed cultivation pods in cold storage.
• Roy proposed training on Raijin Island, and Kaido agreed to bring Jack, Maria, Ulti, Page One, and Yamato alongside the Roy Pirates’ crew.
• Yamato asked Roy to let him join so he could grow stronger and defeat Kaido, and Roy agreed on the condition that he obey orders.
• Roy and Kaido set the departure for dawn in three days, leaving Queen to guard Onigashima and the research base while Dr. Gracia and technicians stayed behind.
• Roy explained that the Ark Maxim would remain visible to the Marines to draw their attention as the crews set out for Raijin Island.

Roy and the Beasts Pirates sailed back to Raijin Island, where Roy planned to train everyone and help those who mastered Life Return learn Internal Forging. The ships reached the island, and the group prepared to enter its dangerous lightning zones gradually.

• Roy and Kaido’s crews sailed from Wano toward Raijin Island, and Kaido ordered his young subordinates to train hard there.
• As the ships neared the island, Roy demonstrated his improved Armament Haki and promised to guide those who mastered Life Return through Internal Forging.
• Roy explained that the crews would acclimate in Raijin Island’s outer zone before advancing into more dangerous areas.
• The crews saw Raijin Island’s barren terrain and its central pool of thunder, which remained largely unchanged despite Roy’s earlier battle with the Golden Lion.

Roy brought his crew and Kaido’s group to Raijin Island to train amid its powerful lightning and gravity. He assigned Life Return practice to his crew, taught Six Powers and Haki training methods to four of Kaido’s subordinates, and established graduated gravity zones across the island.

• Roy stopped the Ark Maxim and the fast ship near Raijin Island, then flew his companions ashore as Kaido carried his group in dragon form.
• The newcomers reacted to the island’s lightning, while Tesoro and Kaido welcomed its energy and the others struggled to adjust.
• Roy assigned his crew to adapt to the outer area and prioritize mastering Life Return, while deciding to teach Kaido’s subordinates training methods for the Six Powers and Haki.
• Roy passed the techniques to Jack, Maria, Ulti, and Page One, who reacted with excitement as Kaido watched and questioned him.
• Roy spread his Gravity Domain across Raijin Island, setting zones from one to twenty times normal gravity and telling everyone to choose a suitable area and train carefully.

Roy began training the Roy Pirates and their allies on Raijin Island, dividing them among zones of increasing gravity and lightning. Tesoro trained at the island’s lightning pool and sensed a lingering will within the ancient lightning.

• Roy activated his Gravity Domain, and everyone struggled to stand under the combined pressure of gravity and lightning.
• Savi instructed Stella, Enel, Pea, Charon, Moria, and Vera in the outer zone as they began training Life Return and adapting to the environment.
• Jack, Ulti, Page One, Maria, and Yamato trained in the middle zone, using their different abilities and tactics to endure the conditions.
• Roy, Bullet, Hawk Eyes, Kaido, and King trained in the inner zone, with Bullet clashing against lightning and Hawk Eyes listening to its paths.
• Tesoro drew powerful lightning from the pool at the island’s core and sensed what seemed to be the lingering will of a previous Rumble-Rumble Fruit user.

Roy trained to understand the world’s rules and, after six months, began teaching his crew the dangerous Internal Forging technique. He guided Savi through his first session, leaving him with a new way to strengthen his Haki through continued practice.

• Roy trained in the fifteenfold gravity zone, refining his body, Haki, Fruit ability, and understanding of the world’s rules.
• After six months, Roy gathered the crew and prepared to teach Savi Internal Forging, while Bullet worried about the risks.
• Roy explained how to sense Armament Haki particles, merge them into the blood, and control them during accelerated circulation.
• Roy used his mental power to guide Savi as he discovered the particles and began circulating them, enduring pain as they collided inside his body.
• Roy ended the guided session and told Savi to remember the sensation and practice gradually, while Savi excitedly said his Haki felt alive.

Roy trained the Roy Pirates in Internal Forging while news of major events across the seas reached them. Dr. Gracia later reported a promising bloodline transplantation model, and Roy decided to return to continue the experiments.

• Roy helped Savi and Tesoro learn Internal Forging, then taught the rest of the crew, while Vera was told to strengthen her physical foundation before learning it.
• The Roy Pirates trained near Raijin Island for a week, and Vera began triple daily physical training under Stella's supervision.
• Over the next half year, Roy and his companions trained as news spread of Roger defeating Golden Lion at Edd War, the Marines promoting Sakazuki, Borsalino, and Kuzan as Admiral candidates, and Byrnndi World being imprisoned.
• Dr. Gracia called Roy to report that bloodline sequencing had revealed records of World Government transplant experiments and that his preliminary model had a theoretical success rate of seventy percent.
• Roy learned that recipients needed exceptional physical strength and regenerative ability, then told Dr. Gracia to continue optimizing the process as he prepared to return.

Roy, Kaido, King, and Moria returned to Wano Country to discuss Dr. Gracia’s bloodline transplantation research and improve its safety. At the research base, Dr. Gracia began showing Roy the experiments, ending with a test subject reacting violently to an Oni bloodline injection.

• Roy proposed that he, Kaido, King, and Moria test the bloodline transplant themselves, while the others stayed on Raijin Island.
• Kaido carried Roy, King, and Moria toward Wano Country in his azure dragon form, and Roy used his ability to increase their speed.
• Roy and the others arrived at the expanded research base beside Onigashima, where Dr. Gracia welcomed them with news of further discoveries.
• Dr. Gracia showed Roy the bloodline research and explained that the researchers had analyzed three genetic bloodlines and conducted simulated experiments.
• Dr. Gracia played footage of clone K-019 receiving purified Oni bloodline essence, and the clone roared as the transformation took a sudden turn.

Roy and Dr. Gracia examined the dangers of transplanting Oni, Lunarian Tribe, and Moria's mixed Oni bloodlines, then discussed a safer way to combine them. Roy proposed using cloning technology to grow a vessel in which multiple bloodlines could fuse before its genes were extracted for transplantation.

• Dr. Gracia showed experiments in which direct Oni, Lunarian Tribe, and Moria bloodline transplants killed their test subjects or caused severe mental problems.
• Kaido, King, and Roy learned that the bloodlines' genetic rank suppression caused rejection, and that dilution only reduced short-term risks.
• Dr. Gracia explained that even high-ranking bloodlines could clash inside a host, with a complete Lunarian Tribe transplant into Kaido carrying over a 40% rejection risk.
• Roy proposed cultivating a vessel with cloning technology and implanting it with several bloodlines while it was still an embryo.
• Roy suggested making his own bloodline primary, then extracting the mature vessel's fused genes for transplantation.

Roy and Dr. Gracia planned a cloning project that would fuse Oni, Lunarian, and mixed Oni bloodlines outside the body, with Roy’s genes as the primary component. The first embryos were set to be cultivated under strict safeguards, while Roy left the research base for Raijin Island and trusted the doctor to oversee the work.

• Roy proposed using clones to carry out the dangerous bloodline fusion, and Dr. Gracia calculated that the theoretical success rate could exceed 90 percent.
• Kaido, King, and Moria discussed the project, and Gracia outlined how the team would create and test the clones.
• Roy required the clones to lack consciousness and pain perception, and King and Kaido agreed to provide security, with Queen assigned to help protect the base.
• Kaido, King, and Roy supplied blood samples, and after three days Gracia presented several stable fusion patterns using Roy’s genes as the primary component.
• Roy told Gracia to prioritize controllability and begin with the most conservative plan, while Kaido and King chose to remain in Wano Country.
• Roy flew with Moria to Raijin Island, where he reassured Moria that the doctor was loyal and that the Roy Pirates could punish the Beasts Pirates if the alliance broke.

Roy began Seastone resistance training on Raijin Island while the crew waited three months for the first fusion clones to mature. Everyone struggled through their first day under the bracelets’ suppression, but they completed their training.

• Roy returned to Raijin Island, reported that the bloodline transplant would take three months, and announced harder training in the meantime.
• Roy distributed Seastone bracelets of varying purity and put on the strongest one, causing his Gravity Domain to vanish and leaving him weakened.
• Yamato grabbed an 80%-purity bracelet and collapsed, so Roy replaced it with a weaker one; Jack, Ulti, Page One, and Maria chose bracelets they could manage.
• Roy ordered everyone to wear their bracelets during training and complete their usual routines under Seastone suppression.
• The crew struggled through the day’s exercises, while Charon resolved to focus on Fish-Man Karate and the Six Powers; Roy praised everyone’s effort after training ended.

Roy and the Roy Pirates trained on Raijin Island for three months, while Roy learned that Seastone suppression made Armament Haki Internal Forging more efficient. When Dr. Gracia reported that bloodline transplants produced far weaker results than expected, Roy suggested the genes might improve as they integrated into their hosts, and the experiments continued as the crew stayed to train.

• Roy discovered that Seastone suppression condensed the circulation of Armament Haki and improved Internal Forging, encouraging the crew to train harder.
• Yamato noticed the crew's unusual training, but Roy brushed off his questions with an excuse.
• Dr. Gracia told Roy that bloodline transplant subjects gained only a fraction of the expected Oni and Lunarian traits, and that weaker hosts suffered greater attenuation.
• Roy proposed that the transplanted genes might grow and integrate over time, prompting Dr. Gracia to plan long-term observations and revise the cultivation process.
• Roy decided the crew would remain on Raijin Island to keep training while Dr. Gracia improved the experiments.

During another three months of training on Raijin Island, Tesoro neared the threshold of Rumble-Rumble Fruit Awakening while Roy guided the crew through increasingly demanding exercises. The chapter ended with the group stronger and Tesoro holding back from rushing his Awakening.

• Tesoro trained in the lightning pool, gradually enduring its deeper and more dangerous currents as he sensed a will within the lightning.
• In the middle of the third month, Tesoro told Roy he felt close to Awakening, and Roy warned him not to force the process.
• Savi, Enel, and Pea improved their Seastone resistance and Internal Forging, and Roy approved Savi's attempt to wear an 80%-purity wristband after testing him.
• Bullet combined Armament Haki with his fruit ability, while Hawk Eyes sharpened his swordsmanship until it surpassed Roy's.
• Vera mastered Life Return and began trying Internal Forging, while Jack and the other Beasts Pirates also grew stronger.

After a year and a half of training on Raijin Island, Tesoro absorbed the island’s lightning and reached the threshold of awakening his Rumble-Rumble Fruit. Roy warned his crew that major changes were coming to the seas and urged them to prepare for the coming era.

• Jack, Ulti, Page One, Maria, and Yamato made major gains through Roy’s training, with Yamato advancing especially quickly.
• Tesoro transformed into a giant of lightning and drew power from the thunderclouds over Raijin Island.
• Tesoro returned to human form and told Roy he had seen lightning’s essence and was close to awakening his Rumble-Rumble Fruit.
• Roy told Tesoro not to rush and to keep strengthening his body and Haki while waiting for the opportunity to awaken.
• Roy said the Roger Pirates were nearing Laugh Tale, the Golden Lion would not abandon his ambitions, and the Navy was increasing its activity, so the crew needed to prepare for upheaval.

After Kaido reported Kozuki Oden’s return to Wano Country and his meeting with Kurozumi Orochi, Roy ordered the Roy Pirates to secure their research base and return immediately. Roy decided that if Oden threatened the base, he would kill him despite the risk of offending Roger and Whitebeard.

• Kaido told Roy that Kozuki Oden had returned to Wano Country, contacted his former followers in Kuri, and met Kurozumi Orochi in the Flower Capital.
• Roy refused to have the Roy Pirates directly target Oden because of their ties to Roger and Whitebeard, but left Oden’s handling to Kaido and assigned his crew to protect the research base.
• Roy gathered his crew, ordered Stella to coordinate with Kaido’s side, Tesoro to prepare the Ark Maxim, and Bullet and the others to gather supplies for an immediate return to Wano Country.
• Roy asked Mihawk about Oden’s strength, and Mihawk said Oden had been among the strongest Great Swordsmen and had likely grown stronger while sailing with Roger.
• Roy told Mihawk he would kill Oden if he threatened the research base, even if that meant offending Roger and Whitebeard.

Roy returned to Wano Country and learned that Kurozumi Orochi had secretly met with a World Government envoy, raising concerns that CP agents were investigating the Beasts Pirates’ base and Wano’s secrets. He sent Kaido and King to confront Orochi and monitor Kozuki Oden while he set out to deal with the agents himself.

• Roy arrived at the base near Onigashima with Bullet and ordered him to prioritize its defense.
• Kaido and King showed Roy reports about Kozuki Oden’s activities and Kurozumi Orochi’s secret meeting with a World Government envoy.
• Roy suspected CP agents were pursuing Wano’s secrets, including its seastone technology and King’s Lunarian heritage, and assigned the defense of the research base to his men.
• Roy ordered Kaido to visit Orochi’s shogun’s mansion publicly and King to track Oden’s movements without approaching him.
• Kaido sailed toward the Flower Capital with Queen, Jack, and elite pirates, while King flew toward Kuri and Roy left Onigashima before dawn.

Roy searched Flower Capital for the CP0 team and captured one of its members to interrogate him about the team’s mission. He learned that CP0 was investigating Onigashima’s research base and had approached Kurozumi Orochi, while Kaido’s fleet headed toward the capital.

• Kurozumi Orochi learned that Kaido was approaching Flower Capital with Queen, Jack, and at least a hundred pirates, and ordered his retainers to receive him normally while secretly reinforcing the mansion’s guards.
• Roy searched the city and identified three CP0 operatives, including a disguised painter watching the shogun’s mansion.
• Roy confronted the painter in his attic hideout and immobilized him when he tried to attack.
• Roy read the painter’s memories and learned that CP0 had sent four people to investigate the research base on Onigashima and assess its research and threat level.
• The painter revealed that CP0 had prioritized contact with Kurozumi Orochi rather than Kozuki Oden, and that Navy intervention depended on the team’s assessment report.

Roy pursued CP0 agents after they discovered his presence, killing one and tracking another to a warehouse where the team planned to request a Buster Call. Roy let Number Three leave to send a report and request reinforcements, then intercepted him to ensure the intelligence he sent would not be genuine.

• Roy caught a CP0 agent at a fish stall, but the agent poisoned himself before Roy could learn where the team leader was.
• Roy found a note from the CP0 member who escaped the teahouse and tracked him to a warehouse.
• Roy overheard the CP0 team leader order Number Three to leave Wano Country, send backup intelligence, and request reinforcements on the scale of a navy fleet.
• Roy decided to let Number Three carry out the plan while intending to replace the real intelligence with false information.
• Roy intercepted Number Three in a secluded alley and used Command: Stillness.

Roy manipulated CP Number Three into sending false intelligence to the World Government, then confronted Captain White Face in the warehouse. White Face revealed his Clone Fruit ability, and Roy trapped the three attackers in his Chaos Domain.

• Roy extracted the contact point, backup, and communication details from CP Number Three, then planted false intelligence and ordered him to destroy and alter the records before leaving Wano Country.
• Roy returned to the warehouse and told Captain White Face that Number Three would deliver a false report claiming there was no research base and that Kurozumi Orochi wanted to trade Seastone.
• Captain White Face used a Six Powers technique to suppress his presence and attack Roy, but Roy detected and blocked him, forcing him to remove his mask and fight openly.
• Captain White Face revealed that the Clone Fruit let him create three real bodies sharing his consciousness, memories, and power, and the three attacked Roy together.
• Roy activated Command: Chaos Domain, distorting the attacks within a ten-meter area and slowing or redirecting the three White Faces.

Roy defeated White Face after surviving the clones’ combined self-destruction and captured the injured CP agent. At the shogun’s mansion, Kaido confronted Kurozumi Orochi about his dealings with the World Government and learned that Kozuki Oden had demanded Orochi step down.

• Roy used his abilities to restrain the three White Faces, but they detonated themselves in a final attack.
• Roy defended himself from the blast, found the real White Face beneath the rubble, and knocked him unconscious before taking him away.
• Kaido arrived at the shogun’s mansion and forced Orochi to admit that a CP0 envoy had offered support in exchange for Seastone processing technology.
• Kaido asked Orochi about Kozuki Oden, and Orochi confessed that Oden had visited three days earlier and demanded that he surrender the shogun’s position.
• Orochi told Kaido that he had refused Oden’s offer to step down and receive protection for himself and the Kurozumi Family.
