Background / History

Sengoku initially investigated Victor after Branch 189 was annihilated in the South Blue, sending Vice Admiral Wood to collect testimony and determine responsibility. Although he did not fully trust the resulting report, he ended the inquiry after Victor's destruction of the Heide Pirates stabilized the situation and generated favorable public coverage for the Navy 4 6.

He regarded the losses suffered after the God Valley Incident as a reason to develop a new generation of Navy elites. Sengoku identified Victor, Sakazuki, and Borsalino—each acknowledged by Zephyr—as future pillars of the Navy, assigning Victor to Branch G5 in the New World to gain experience and accumulate merit 6 7.

Sengoku deliberately arranged operations such as the campaign against Jonathan's crew to serve as a proving ground for the younger officers. Victor's performance convinced him to seek Kong and the Gorosei's support for further cultivation of Victor and the new generation 12 13.

Personality

Sengoku prioritizes stability, order, and the Navy's ability to maintain the balance of the seas. He is willing to accept imperfect outcomes when they preserve public confidence in the Navy or prevent wider disorder 6 44.

A careful strategist, he prefers preparation and manageable costs over reckless escalation. He resisted an immediate war with Whitebeard because the Navy was not ready to absorb the losses such a conflict could cause 190 197.

His commitment to institutional order increasingly clashes with Victor's radical methods. Sengoku condemns Victor's willingness to accept immense civilian casualties, yet faces difficulty controlling an organization divided between Victor's supporters and his own faction 124 151 172.

Abilities & Skills

Strategic Command

Sengoku designs operations around long-term personnel development as well as immediate victory.

• Used Jonathan's pirate group as a controlled test for the Navy's younger generation, allowing promising officers to gain combat experience and prestige 12 13.
• Recognized Victor's potential early and arranged his New World deployment, promotions, and development as an Admiral candidate 6 7.
• Planned cautiously around powerful threats such as Whitebeard, accounting for the Navy's readiness and expected casualties 190 197.

Intelligence Operations

Sengoku maintains intelligence networks and uses gathered information to direct Navy operations.

• Sent Vice Admiral Wood to investigate Victor's conduct in the South Blue 4.
• Placed Flywheel as a spy among the Flying Pirates to monitor Golden Lion and Roger; Flywheel reported directly to Sengoku via Den Den Mushi 47.
• Used Vivre Card fragments to track the condition of undercover operatives 47.

Organizational Management

Sengoku attempts to strengthen the Navy through structural reforms, appointments, and factional consolidation.

• Proposed the Sea Warriors plan, intended to recruit pirates to restrain other pirates as the Pirate Era intensified; the Gorosei approved the plan 95 96.
• After becoming Fleet Admiral, placed dove-faction officers in key Headquarters and branch command positions to limit Victor's influence 151.
• Promoted Kizaru to Admiral while suspending Aokiji's duties, seeking to contain Aokiji's conflict with CP0 and preserve Navy order 163.

Policies and Initiatives

• Sea Warriors Plan — Sengoku's proposal to use selected pirate forces against other pirates, reducing the Navy's burden as major pirate powers expanded 89 95 96.
• New Generation Development — A long-term effort to cultivate Zephyr's strongest students into the Navy's future leading force, particularly Victor, Sakazuki, and Borsalino 6 13.
• SWORD — A secret unit personally trained by Sengoku to monitor major New World threats; its annihilation in the Calm Belt was a major setback during his tenure as Fleet Admiral 153 154.

Relationships

• Victor — Initially viewed Victor as a crucial future fighting force and personally sent him to the New World for development. Their relationship deteriorated into a struggle over the Fleet Admiral position and the Navy's direction 6 7 124 150.
• Kong — Sengoku's superior and strategic partner. Kong accepted Sengoku's Sea Warriors plan and later received Sengoku's resignation after the Summit War 95 96 213.
• Tsuru — Long-standing comrade and trusted colleague. She advised Sengoku on Victor's potential and assisted in major Navy operations 4 6 90.
• Zephyr — Sengoku's comrade of decades. Sengoku enlisted Zephyr's help to gather and counsel dissatisfied dove-faction officers before the Fleet Admiral succession 146 148.
• Aokiji — Sengoku supported Kuzan's promotion and relied on him as a representative of the dove faction, but their relationship fractured after Aokiji confronted the Punk Hazard experiments and defied World Government agents 124 159 163.
• Kizaru — A dependable but politically isolated subordinate. Sengoku entrusted him with sensitive investigations and elevated him to Admiral in exchange for pursuing Aokiji 134 154 163.
• Garp — Fellow veteran officer whose straightforward approach often contrasts with Sengoku's strategic pragmatism 47 93 213.

Story Role / Major Arcs

Fleet Admiral Succession

Sengoku became Victor's principal rival for the Fleet Admiral position as Victor's prestige surged after defeating Golden Lion. Sengoku advocated Kuzan's promotion over Victor's recommendation of Sakazuki, criticizing Victor's tactics and the civilian cost of his operations 123 124.

The Gorosei ultimately appointed Sengoku as Fleet Admiral. He publicly remained composed, but inherited a Navy already divided between Victor's hawk faction and the dove faction that increasingly looked to Sengoku for leadership 150 151.

Internal Navy Crisis

As Fleet Admiral, Sengoku reassigned key branch posts to dove-faction officers and attempted to curb Victor's influence. His efforts were undermined by Blue Sea Society resistance, the destruction of his SWORD unit, mounting pirate attacks, and expensive Science Unit demands 151 154.

Aokiji's actions against the Punk Hazard experiments and CP0 further weakened Sengoku's authority. Under pressure from CP0, Sengoku suspended Aokiji and appointed Kizaru as an Admiral, leading to Aokiji's eventual escape after fighting Kizaru 159 163 166.

Sengoku's suspension of Victor and Zephyr triggered mass protests, a strike, and a military-academy boycott. He refused to yield to demands for their release, public apology, disclosure of Aokiji's departure, and his own resignation 172 175 176.

Summit War and Resignation

Sengoku sought Pacifista support from Vegapunk while preparing for the conflict caused by Ace's public execution and Whitebeard's impending attack on Marineford 196 198.

During the Summit War, Sengoku advanced Ace's execution on orders from the Gorosei, allowing the conflict to end quickly after Whitebeard's death. The Whitebeard Pirates and Red Hair Pirates were allowed to withdraw 212 213.

Though the war's circumstances were largely outside his control, Sengoku resigned as Fleet Admiral and accepted responsibility for its outcome. Kong subsequently offered him the position of Inspector General 213.
