Power Progression

Background / History

Sengoku oversees Marine Headquarters as Fleet Admiral and maintains a long-standing, combative friendship with Vice Admiral Garp. When Garp reports that Roya learned to freely wield Conqueror’s Haki in only a little over three months, Sengoku is shocked but orders Garp to cultivate him carefully for the Marines’ next generation 4.

After Garp recommends Roya and tests his combat ability, Sengoku exceptionally promotes him from major to Marine Headquarters rear admiral. He immediately entrusts Roya with receiving the captured Portgas D. Ace from Marshall D. Teach and escorting him to Impel Down 7 8.

Roya’s defeat of Teach puts Sengoku in a political dilemma: although impressed, he orders the information concealed so the Marines can still exploit the Seven Warlords system during the escalating crisis surrounding Ace 13. Sengoku later relies on Roya for the sensitive assignment to summon Donquixote Doflamingo, having come to trust his strength and conduct under pressure 16.

When Roya arrests Doflamingo and Jack the Drought, Sengoku publicly challenges the decision because of the danger of provoking Kaido. Privately, however, he accepts the arrests as justified after Roya presents evidence of their Artificial Devil Fruit trade; Sengoku had deliberately refrained from stopping him while he lacked proof 24.

Kaido’s assault on Marine Headquarters forces Sengoku into battle alongside Garp. He uses his Buddha form against Kaido, but the Emperor emerges unharmed, leading Sengoku and Garp to recognize that their attacks are insufficient 28 29. After Roya defeats Kaido, Sengoku has him personally escort the captive Emperor to Impel Down, judging ordinary guards unable to prevent an escape 33.

Sengoku reports Kaido’s capture to Commander-in-Chief Kong and supports using the victory to strengthen Marine authority. The Marines subsequently create the unprecedented position of Fourth Admiral and appoint Roya to it 35 36 37.

Following Roya’s killing of Saint Charlos, Sengoku is forced to balance Marine interests against demands from Mary Geoise. He reprimands Roya for violating his duties as an admiral, but negotiates a temporary imprisonment in Impel Down rather than an immediate harsher punishment and promises to seek a solution 47. At the Five Elders’ council, he argues that Roya’s record and strength are indispensable for the coming war against Whitebeard, but the Elders rule that Roya must die for challenging Celestial Dragon authority 50.

As the public execution of Ace begins, Sengoku announces to the entire world that Ace is Gol D. Roger’s biological son, turning the execution into a demonstration of Marine authority and a provocation to Whitebeard 65. The arrival of Whitebeard, Big Mom, and Kaido transforms the planned operation into a war against three Emperors. Sengoku orders every Marine to engage, but increasingly recognizes that the Marine force is outmatched and that Roya may be its only decisive asset 68 74.

Although the Five Elders demand that he prevent Roya’s resignation and deliver him to Mary Geoise so they can investigate his ability to wield multiple Devil Fruit powers, Sengoku initially resists. He argues that forcibly retaining Roya would further damage Marine dignity, but ultimately agrees only to attempt persuasion under pressure from the Elders 136 137. His public offer to pardon and restore Roya as Fourth Admiral fails, as Roya remains determined to leave the Marines 76 138.

During the later stages of the Summit War, Sengoku continues coordinating the Marine response across several fronts. He orders Kuzan to reinforce Sakazuki against Big Mom and personally joins Garp in trying to contain Kaido and the Blackbeard Pirates 117. He also fights pirate officers directly in Buddha form when the battlefield becomes too chaotic for conventional Marine forces to manage 195.

Roya’s formation of the Justice League and recruitment of dozens of Marine soldiers finally pushes Sengoku beyond his limit. Viewing the act as a public humiliation and a direct challenge to Marine authority, he attacks Roya with a full-strength shockwave, inflicting only a minor injury 173 174. Sengoku continues fighting when Roya refuses to retract his condemnation of the Marines’ obedience to the Celestial Dragons, but realizes that Roya is still withholding much of his strength 175 176.

When Roya prepares to leave Marineford, Sengoku ultimately allows it rather than risk provoking the release of the Tenseigan’s full power and destroying the headquarters. He prioritizes the survival of Marineford and its soldiers over preserving the Marines’ public image, even as Sakazuki refuses to accept the decision 178.

Following the Summit War, Sengoku steps down as Fleet Admiral and becomes Marine Inspector General. He and Kong later debate the next Fleet Admiral’s appointment: Sengoku favors Kuzan’s steadier disposition, while Kong supports Sakazuki’s absolute justice. Sengoku accepts that the older generation must eventually make way for its successors 202. As Inspector General, he remains influential enough to attend high-level Marine meetings and openly warns Sakazuki against allowing Kaido and Big Mom’s alliance to act unchecked against Roya 229 230.

Personality

Sengoku is a responsible commander whose decisions are shaped by both justice and the Marines’ strategic position. He recognizes the criminality of Doflamingo and Jack’s dealings, yet fears the consequences of antagonizing Kaido while the Marines prepare for Whitebeard 24.

He is pragmatic toward powerful subordinates. Sengoku promotes Roya rapidly, entrusts him with major operations, and accepts that conventional restraints are meaningless against him; during Roya’s transfer to Impel Down, Sengoku relies on Roya’s promise rather than escalating the situation with force 7 37 48.

Despite his strict manner, Sengoku values Roya and repeatedly attempts to protect him from the World Government’s punishment. His conflict with the Five Elders shows that he places military necessity and the Marines’ future above unquestioning compliance with Celestial Dragon authority 47 50.

Sengoku is nevertheless bound by the responsibilities of his office. Though he privately resents the Five Elders’ treatment of the Marines and envies Garp’s freedom from their control, he ultimately submits to their demand that he attempt to retain Roya 136 137. He is acutely conscious that every major decision affects Marine prestige, public perception, and the lives of his subordinates.

His conduct during Roya’s departure illustrates his strategic restraint. Sengoku is angered by Roya’s defection and recruitment of Marines, but accepts the humiliation of letting him leave because a prolonged battle could destroy Marineford while multiple Emperors remain on the field 173 178.

After retiring as Fleet Admiral, Sengoku becomes more relaxed and candid. He openly criticizes Sakazuki’s policies as Inspector General while no longer bearing the direct burden of command, though he remains deeply invested in the Marines’ future and stability 202 230.

Relationships

• Garp — Long-time friend, rival, and battle partner. Their banter contrasts with their mutual trust; they previously joined forces against Golden Lion and again fought Kaido together. Though they differ over Roya and Sakazuki, they continue to coordinate instinctively in crises. 4 28 117 154
• Roya — Former high-value Marine subordinate and Fourth Admiral. Sengoku approves Garp’s training of Roya, promotes him from major to rear admiral and later Fourth Admiral, and initially tries to protect him after the Celestial Dragon incident. Their relationship deteriorates after Roya resigns and forms the Justice League, though Sengoku ultimately allows him to depart rather than endanger Marineford. 4 7 37 47 50 173 178
• Kong — Commander-in-Chief to whom Sengoku reports Kaido’s capture and Roya’s role in the victory. Kong approves Sengoku’s plan to use the event to bolster Marine authority; after Sengoku’s retirement, the two discuss the Fleet Admiral succession. 35 202
• Kizaru — Former Admiral under Sengoku’s command. Sengoku sends him against Kaido and later orders him to intervene at Sabaody. During the Summit War, Sengoku repeatedly deploys him against major pirate threats and to support Sakazuki. 25 26 42 117 154
• Sakazuki — Initially an Admiral under Sengoku’s command and later his successor as Fleet Admiral. Sengoku repeatedly rebukes Sakazuki for allowing personal hostility toward Roya to disrupt Marine operations, and later criticizes his decision to exploit the Kaido–Big Mom alliance against Roya. 47 95 143 230
• Kuzan — Former Admiral whom Sengoku considers the more balanced candidate for Fleet Admiral. Sengoku favors Kuzan over Sakazuki because of Kuzan’s steadier temperament, though Kong ultimately prefers Sakazuki’s absolute justice. 117 202
• Kaido — Enemy Emperor whose attack on Marine Headquarters creates a major strategic crisis; Sengoku ultimately orders his imprisonment in Impel Down. Kaido later escapes and again becomes one of the greatest threats Sengoku must contain during the Summit War. 24 25 33 117
• The Five Elders — World Government superiors who reject Sengoku’s arguments for sparing Roya and prioritize the protection of Celestial Dragon authority. Later, they order Sengoku to retain Roya so that the Government can study his multiple Devil Fruit powers. 50 136 137
• Big Mom — An enemy Emperor whom Sengoku considers too dangerous to leave unchecked. He and Garp jointly confront her to prevent her from destroying Marineford during the Summit War. 146 158
• Ace — Sengoku turns Ace’s execution and Roger lineage into a worldwide declaration of Marine authority, despite knowing that the decision will provoke Whitebeard into war. 65
