Chapter Summaries

Sun Keiyun explained how the Marines’ focus on strength and lack of recognition for ordinary soldiers eroded their morale, then proposed enlisted grades and a merit system to reward their service. Sengoku eagerly welcomed him into the Marines and offered him a choice of Devil Fruits, leaving Sun Keiyun excitedly browsing the Marines’ catalog.

• Sun Keiyun argued that ordinary recruits lost hope when they could not match the talented Marines celebrated in the newspapers, and Sengoku admitted the Marines had failed to address the problem.
• Sun Keiyun rejected Akainu’s claim that Marines should fight only for justice and explained that leaders had to provide soldiers with rewards, honor, and opportunities for advancement.
• Sun Keiyun proposed enlisted grades with benefits and a merit system based on service and contributions, including public commendations for outstanding achievements.
• Sengoku recognized Sun Keiyun’s proposal as a major contribution, urged him to join the Marines, and offered him a choice of Devil Fruits.
• Sun Keiyun accepted the offer and opened the Marines’ illustrated Devil Fruit catalog.

Sun Keiyun chose and ate the Card Fruit, discovering that Xingchen could absorb its power while allowing him to use its abilities. He tested his new power by creating a card that Garp caught, and found that the Fruit suited him well.

• Sun Keiyun compared the Navy's Devil Fruits and chose the Card Fruit over several alternatives, including the Cloud-Cloud Fruit and Carbon-Carbon Fruit.
• Sengoku retrieved the Card Fruit from a hidden room, and Xingchen sensed that it carried a trace of an Ancient Star Tree fruit.
• Xingchen told Sun Keiyun it could absorb the Devil Fruit's power and let him use its abilities, so Sun Keiyun ate the Fruit.
• Sun Keiyun learned that he could create cards from different materials and shapes, then made a Plum Blossom 3 card and flicked it at Garp.
• Garp caught the card and estimated its power at 3,000 doriki, while Sun Keiyun said the Fruit suited him.

Sun Keiyun outlined a Navy reform plan to Sengoku, using the East Blue as a pilot region and prioritizing anti-corruption and training. After Sengoku learned Colonel Rat had covered up his collusion with Arlong, he ended the meeting to investigate and handed reform discussions to Akainu and Aokiji, while Gion offered Keiyun a place to stay.

• Sun Keiyun proposed piloting Navy reforms in the East Blue, beginning with purges of corrupt officers and better training.
• Sun Keiyun revealed that Arlong had killed Bellemere and terrorized her village for years, despite Colonel Rat's report blaming the Straw Hat Pirates.
• Sengoku learned Rat was still a serving colonel and ordered an investigation before ending the meeting and keeping Akainu and Aokiji behind.
• Gion took Sun Keiyun from the meeting and offered him a room at her home near Marine Headquarters.
• Sun Keiyun saw Marines recognize him as he left and expected his reputation to grow further by the Summit War.

Sun Keiyun visited Gion at her home, where they rebuffed Chaton's proposal and grew closer. He tested the Card Fruit's abilities and prepared to draw a Blue-Eyes White Dragon card.

• Gion brought Sun Keiyun home with her arm linked through his, and Chaton confronted them with his eighty-sixth marriage proposal.
• Gion told Chaton she liked Sun Keiyun and rejected him, while Sun Keiyun challenged Chaton over using his rank to steal someone's girlfriend.
• Chaton left in frustration after hearing Gion agree when Sun Keiyun asked if he could wake up with her.
• Gion made milk tea as Sun Keiyun asked Xingchen whether it could absorb his Devil Fruit and learned that it could.
• Sun Keiyun created paper, aluminum alloy, steel, silver, gold, and silicon cards, then decided to draw a Blue-Eyes White Dragon.

Sun Keiyun discovered how to create cards by editing information and used his stamina to make dragons, troops, generals, and other cards before the public trial. After Gion saw the cards’ power, she agreed to test Zhao Zilong and asked Sun Keiyun to make her powerful female swordsmen.

• Sun Keiyun created three Blue-Eyes White Dragon cards, then made a Nine-Tails card that had an elaborate shell but no combat power.
• Sun Keiyun produced hundreds of low-tier infantry, archer, cavalry, and modern troop cards, then planned more powerful generals, environments, and equipment.
• Gion brought Sun Keiyun milk tea and examined his cards, including Lady Mi and Zhao Zilong, whose abilities impressed her.
• Sun Keiyun explained that his summoned cards’ attack values corresponded to Doriki and invited Gion to test Zhao Zilong at the training ground.
• Sun Keiyun used a Storage Card to gather the cards from the table, and Gion asked him for a copy of Zhao Zilong and five powerful swordsmen.
• Sun Keiyun refused to duplicate the unique five-star Zhao Zilong but agreed to make Gion five female swordswomen.

Sun Keiyun summoned God of War Zhao Zilong with his Card Fruit and tested him against Gion, whose skillful spear-wielding opponent overwhelmed her despite having lower Doriki. Gion treated the fight as a lesson in technique and kept improving, while Zhao Yun still had five more attack-power stacks available.

• Marines gathered to watch Sun Keiyun and Gion arrive at the training ground, where Sun Keiyun summoned Zhao Zilong from a card and ordered him to defeat Gion.
• Zhao Yun's first charge pierced Gion's shoulder and forced her to use Haki, then he withdrew before she could retaliate; Gion refused to accept the apparent loss and demanded another round.
• Gion fought more seriously in the second round, but Zhao Yun's speed, reach, and spear techniques kept her on the defensive as Kizaru praised the horse and discussed Devil Fruit training with Sun Keiyun.
• Gion began using wind around her sword to match Zhao Yun's technique, but Zhao Yun finished the second round without a scratch while she suffered several bloody wounds.
• Sun Keiyun realized Zhao Yun's stable attacks and refined spear arts made him far more formidable than his Doriki suggested, and the fight remained unfinished with five attack-power stacks left.

Zhao Yun's escalating attacks pushed Gion to awaken a new sword technique, and she believed she had been mortally wounded after defeating him. Sun Keiyun healed her with a card and walked away, leaving Gion to face the crowd after confessing her feelings for him.

• Zhao Yun's Doriki Value rose to 4,100, and he and Gion fought while Marine onlookers wondered whether their wind-coated weapons revealed a new power system.
• Zhao Yun wounded Gion in three rapid exchanges, and she realized she had to use her incomplete new technique to survive his next charge.
• Under pressure, Gion fused Armament Haki with wind and struck Zhao Zilong with her blazing red sword, shattering him as she collapsed with a chest wound.
• Gion told Sun Keiyun that she had succeeded in finding the path he had described and confessed that she had fallen for him.
• Sun Keiyun let Gion fall, revealing that a Healing Spell card had restored her wounds, then walked away as onlookers questioned her about her confession.

Sun Keiyun repaired and fused six Zhao Zilong Cards into a stronger card, then Gion confronted him about her public confession and became his girlfriend. They discussed the coming war with Whitebeard and planned to propose a Navy supervisory unit, with Gion serving as its public representative.

• Sun Keiyun reflected on Gion’s high-frequency particle blade after it shattered Zhao Zilong’s defense, then repaired the damaged card.
• Sun Keiyun fused six Zhao Zilong Cards into one, raising its initial attack power to 4200 and its Seven In, Seven Out bonus to 800 per stack.
• Gion confronted Sun Keiyun for not revealing that he had a healing card and insisted he answer her public confession; they became a couple.
• Gion asked Sun Keiyun how he knew Whitebeard’s forces would come to war, and he argued that the Navy’s strength made victory inevitable.
• Sun Keiyun proposed a supervisory unit and battlefield commander for the war, suggesting Gion take the position; she agreed to speak with Fleet Admiral Sengoku the next day.

Sun Keiyun flew to Mary Geoise to scout the city and investigate its hidden structure, but Star could not scan through the strange force field surrounding it. He memorized the city’s layout and left, planning to return after the Summit War with a proper plan.

• The Chat Group welcomed Beginning Sun Keiyun, who explained that he had transmigrated into a modern world and survived a bus bombing, while the others suggested investigating its time loop.
• Hokage Keiyun shared a spirit-rune book and told Beginning Sun Keiyun to use the Star Tree’s power to investigate Wang Mengmeng.
• Sun Keiyun used an Invisibility Card and wings to fly back to Mary Geoise at three times the speed of sound.
• Star reported that Mary Geoise had a solid metal structure beneath its outer buildings and a force field that blocked scans, leaving the underground library’s location unknown.
• Sun Keiyun decided to return after the Summit War with a proper plan, promised Star some of Eve’s wood power, and left after memorizing the city.

Gion gathered more than fifty Navy swordsmen who wanted to learn her Wind-Following Swordsmanship and explained that they had to share her understanding of justice. She argued that justice was fairness grounded in society’s values, leaving Momonga and the other Marines to reconsider what the Navy upheld.

• Gion opened her door to find Momonga and more than fifty Navy swordsmen seeking to learn her swordsmanship.
• Gion explained that Wind-Following Swordsmanship was a newly developed style that she wanted others to study and help advance.
• Gion asked Momonga what justice meant to him and rejected “steadfast justice” as a description of justice.
• Gion told the swordsmen that anyone learning her style had to understand fair judgment and stand with her.
• Gion defined justice as fairness aligned with mainstream social values and argued that people could kill pirates because humans were equal to one another, unlike humans and fish.

Gion taught Marine swordsmen Sun Keiyun’s justice-based swordsmanship doctrine, then learned he belonged to a new Revolutionary Army faction that planned to reform the Marines from within. After Gion agreed to seek frontline fame and an admiral’s rank, Sengoku summoned Sun Keiyun to command the Shichibukai, and he began addressing them.

• Gion taught Marine swordsmen that conviction in justice could make their swordsmanship more resolute, then rested with Sun Keiyun.
• Gion confronted Sun Keiyun about his suspected Revolutionary Army ties, and he revealed his plan to build a new faction by recruiting Marines and pursuing top-down reform.
• Sun Keiyun urged Gion to leave her rear-area assignment, earn fame on the front lines, and rise to admiral; they discussed taking on Whitebeard and Marco for merit.
• Sengoku summoned Sun Keiyun to Marine Headquarters, where he found Donquixote Doflamingo, Gecko Moria, Bartholomew Kuma, Boa Hancock, and Dracule Mihawk waiting.
• Sengoku ordered the Shichibukai to follow Sun Keiyun’s arrangements, and Sun Keiyun stepped forward to speak to them.

Sun Keiyun used flattery, provocation, and promises of insight to persuade the Shichibukai to take the Marine assignments seriously. Doflamingo agreed to fight Marco, and Mihawk claimed Jozu as his opponent after Sun suggested a path toward advancing his swordsmanship; Sun then called on Boa Hancock.

• Sun Keiyun introduced himself as the Shichibukai’s temporary leader and planned how to secure their cooperation for the coming battle against the Whitebeard Pirates.
• Sun Keiyun provoked Doflamingo into accepting the task of pinning down Marco, then praised Doflamingo’s rule and business ventures until Doflamingo agreed to serve the people while remaining a pirate.
• Sun Keiyun told Mihawk that grass, wood, bamboo, and stone could all become swords, and mentioned that Gion had broken through as a Great Swordmaster.
• Sun Keiyun proposed that Gion face Jozu, prompting Mihawk to claim Jozu for himself and pledge to break through the world’s strongest defense.
• The remaining Shichibukai worried that Sun Keiyun would target them next, and he called on Boa Hancock.

Sun Keiyun persuaded Hancock that Kuja Country needed an alternative to plundering and proposed that its warriors join the Marines. Hancock agreed to discuss the plan with her people, then eagerly accepted Garp as their liaison after learning he was Luffy’s grandfather, and prepared to return home.

• Sun Keiyun explained that Kuja Country could not rely on Hancock’s strength and plundering forever, and Doflamingo identified its economic problems as limited production, little land, and no trade.
• Sun Keiyun proposed that Amazon warriors serve in the Marines, where their salaries and influence could help Kuja Country and strengthen the Marine ranks.
• Hancock was tempted by the proposal but initially said she would return to discuss it with her people; Sun Keiyun then suggested the warriors’ marriages could challenge their restrictions on marrying outsiders.
• Hancock eagerly accepted Garp as the Marines’ liaison after Sun Keiyun revealed that Garp was Luffy’s grandfather.
• Sengoku agreed to send Hancock home with Vice Admiral Momonga instead of having her fight, and Hancock hurried to tell her people about the proposal.

Sun Keiyun arranged the Shichibukai’s roles for the coming battle, then persuaded Moria and Doflamingo to lend Perona and Baby-5 to the Marines. Kuma left to report his impressions of Sun Keiyun to Dragon, while Moria and Doflamingo agreed to send their crew members to Marine Headquarters.

• Sun Keiyun dismissed Moria from a captain assignment because he had lost to Luffy, but Moria insisted on fighting Vista, Blamenco, and Rikyo.
• Sun Keiyun tasked Kuma with supporting the three captains and preventing outside interference, then allowed Kuma, Hancock, and Hawk Eyes to leave.
• Sun Keiyun asked Moria to lend Perona to the Marines, and Moria agreed to have Vice Admiral Gion escort her back.
• Sun Keiyun asked Doflamingo to lend Baby-5, and Doflamingo agreed to send her over in a day.
• Kuma left planning to report Sun Keiyun’s strategic abilities to Dragon, while Doflamingo wondered what Sun Keiyun intended to do with Baby-5.

Sun Keiyun told Sengoku, Hawk Eyes, and Akainu a story about an archer who reached the highest skill by abandoning his bow, then argued that benevolence could win what force could not. Sengoku reconsidered his campaign against pirates and wondered if it was time for him to retire after the coming battle.

• After the Shichibukai left, Sun Keiyun praised Sengoku’s strength, then began telling him the story of Ji Chang and his archery teachers.
• Hawk Eyes and Akainu entered while Sun Keiyun recounted how Ji Chang trained under Fei Wei, challenged him, and was directed to seek Gan Ying.
• Ji Chang found Gan Ying, learned The Art of Not Shooting, and returned years later without his bow or arrows.
• Hawk Eyes recognized the lesson as a swordsmanship realm beyond relying on a weapon and regained confidence in his path.
• Sun Keiyun told Sengoku that force inspired fear while benevolence and righteousness could win the Four Seas’ submission.
• Sengoku reflected on the Marines’ failed efforts to suppress piracy and wondered whether he should retire after the battle.

Sun Keiyun advised Sengoku to turn the coming battle into a decisive victory over Whitebeard’s forces, then used a card simulation to expose the dangers of executing Ace because of his parentage. The mock battle began with Whitebeard’s fleet attacking Marine Headquarters, while Sengoku reconsidered how the execution should be presented.

• Hawk Eyes left after hearing Sun Keiyun describe several possible paths to becoming a Great Swordmaster, and Sengoku asked Sun Keiyun for advice about the war.
• Sun Keiyun argued that the Marines should destroy Whitebeard’s entire force and seize its territories rather than merely defend Ace’s execution, and Sengoku accepted the strategic case.
• Sun Keiyun created a card battle simulation and played Whitebeard’s side against Sengoku’s Marines, but first challenged Sengoku’s plan to announce that Ace was the Pirate King’s son.
• Sun Keiyun argued that punishing Ace for his father’s identity would legitimize family retaliation and trap pirates’ descendants in a cycle of crime, so Sengoku agreed that Ace should be executed for his own crimes instead.
• Sengoku decided to rewrite the execution plan, and Sun Keiyun summoned the Moby Dick and Whitebeard’s crew to begin their simulated assault on Marine Headquarters.

Sun Keiyun and Sengoku tested a Card Battle Simulation of the Marineford war, where the Whitebeard Pirates broke through the Marines’ defenses despite Sengoku’s powerful cards. Impressed by Sun Keiyun’s tactics and the simulation’s exposed weaknesses, Sengoku put him in charge of drafting a new battle plan for Ace’s public execution.

• Sengoku froze the bay’s waves and raised the iron walls, while Sun Keiyun sent the Whitebeard Pirates charging across the ice.
• Akainu’s card fought Marco and Vista, while Whitebeard stopped Kizaru and Little Oars damaged an iron wall before Sengoku’s Admirals brought him down.
• Izo and Jozu joined the attack, Whitebeard’s forces reached the drill ground, and Sengoku discovered that the Shichibukai cards were unreliable or unwilling to fight.
• Sengoku ended the simulation after recognizing flaws in his battle arrangements and Sun Keiyun’s effective command.
• Sengoku assigned Sun Keiyun to write a new battle plan, offered him classified Impel Down information and Navy support, and scheduled another simulation for the following afternoon.

At Marine Headquarters, Sengoku publicly read Ace’s documented crimes before the Whitebeard Pirates arrived to rescue him. Sun Keiyun challenged Whitebeard over whether he had given his sons a better future, leaving Whitebeard’s crew shaken just as battle approached.

• Sengoku announced Ace’s trial and read aloud records of the crimes committed by Ace and the Spade Pirates.
• Ace told Sengoku to stop, but Sengoku insisted the charges were true and said Ace had to take responsibility for his own actions.
• Whitebeard arrived in the bay with more than forty pirate vessels, and Ace tearfully asked why he had come to save him.
• Sun Keiyun confronted Whitebeard, questioning whether he had been a responsible father to his pirate crew.
• Sun Keiyun argued that Whitebeard could have built a peaceful homeland for his sons instead of keeping them pirates, unsettling Whitebeard and his commanders.

Sun Keiyun’s public challenge deepened distrust within the Whitebeard Pirates, and the Marines began using their defenses to wear down the invading fleet. Whitebeard reached the plaza and answered Sun’s accusations before Garp stepped forward to face him in what both men expected to be their final battle.

• Sun Keiyun’s speech convinced Whitebeard that the Marines had created an unsolvable crisis of trust among his crew, while the Gorosei praised his strategy and Dragon considered meeting him to exchange ideas.
• Whitebeard raised enormous waves with his Tremor-Tremor Fruit, but Aokiji froze them into walls of ice as Sun ordered more than a thousand cannons to fire on the pirate fleet.
• Whitebeard’s shells were intercepted at great cost, and Doflamingo stopped Marco from flying through his string trap by overpowering him with his awakened Devil Fruit.
• Whitebeard used an airquake to propel all forty-six ships to the bay wall, but Kuma blasted Little Oars away before he could serve as a ladder for the pirates.
• Whitebeard leaped onto the plaza and told Sun Keiyun that he supported his children’s freedom by standing ready to protect them.
• Sun Keiyun revealed Garp, who challenged Whitebeard to fight with him in what both old men believed might be their final battle.

Sun Keiyun’s plan let the pirates reach the plaza, only for the Marines to destroy their ships and unleash three-stage rifle volleys against them. As the pirates began suffering heavy losses, Oars ordered Vista and several commanders to break the Marine formation and others to engage Kuma.

• Garp fought Whitebeard while Sun Keiyun turned his attention to Oars and the advancing pirates.
• Jozu blocked Kuma’s Air Cannon and faced Mihawk, while Vista engaged Kuma and the pirate commanders reached the plaza.
• Aokiji froze the bay, and the two Admirals destroyed the Whitebeard Pirates’ ships with lasers and magma.
• Sun Keiyun ordered the Marines to form three ranks and fire in rotation, killing hundreds of pirates with successive volleys.
• As Whitebeard and Garp remained locked in battle and Jozu struggled against Mihawk, Oars ordered Vista and several commanders to attack the gun formation and others to deal with Kuma.
