Sengoku

Biodata

Background / History

Sengoku initially remains within the Navy despite growing alarm at the World Government's conduct, including its willingness to work with pirates against Byakuya. Discussions with Tsuru and intelligence relayed through Gion force him to confront the Navy's increasingly uncertain position beneath the Government 609 612.

When Byakuya demands that the Navy either join him or lose its admirals as spoils of war, Sengoku investigates Wano Country rather than immediately committing. The conditions he observes there, together with the testimony of Garp and the admirals, weaken his belief that the World Government is the better alternative 650 749.

Sengoku initially suspects that Byakuya intends to replace the Celestial Dragons rather than abolish their system. Byakuya rejects this, stating that no new Celestial Dragons will be allowed after the World Government falls; Sengoku ultimately decides that an uncertain future under Byakuya is preferable to continued rule by the existing regime 652 676.

He publicly announces that he will cooperate with Byakuya and gives Navy personnel the choice to accompany him or remain behind. To justify the decision, he openly reveals the Celestial Dragons' atrocities, including the God Valley massacre, and argues that the Navy has been used to sustain their rule 662 670.

A majority of the Navy chooses to follow Sengoku. He leads them in rebellion, later arriving in Wano Country with a large force and confirming that he has disbanded the Navy's former allegiance to the World Government 674 688 690.

Personality

Sengoku is deeply conscientious and reluctant to make irreversible decisions alone. Even after deciding to rebel, he gives Marines time to consider their futures and repeatedly emphasizes that they should not be forced into a war they do not understand 675 677.

His sense of justice is tempered by disillusionment. He once believed that maintaining the Navy's connection to the World Government preserved at least a measure of protection for civilians, but concludes that this compromise is no longer acceptable once he recognizes the Celestial Dragons' oppression and the Navy's complicity 676 749.

Sengoku remains troubled by the personal cost of his choice. He feels guilty confronting Kong, his former mentor, and recognizes that his defection will be viewed as betrayal from the World Government's perspective 675 676.

Relationships

• Tsuru — Trusted confidante and advisor. She challenges Sengoku's hesitation, supports his final decision, and helps him manage the Marines' transition 609 675 690.
• Byakuya — Former opponent turned ally. Sengoku initially doubts Byakuya's motives, but joins him after evaluating Wano Country and the World Government's corruption 650 652 662.
• Garp — Longtime Navy associate who advocates for change more readily than Sengoku. His experiences in Wano contribute to Sengoku reconsidering his position 650 655 749.
• Gion — A Navy operative who had been with Byakuya and provided intelligence through Tsuru before Sengoku's defection 609 233.
• Kong — Sengoku's former mentor and the Armed Forces' Commander-in-Chief. Sengoku asks him to oppose the World Government, but Kong refuses; their opposing loyalties make a battle inevitable 675 678 749.
• Navy personnel — Sengoku's authority and prestige lead most Marines to follow him, though he insists that each person choose whether to join the rebellion, remain in Wano, or leave 670 674 692.
