Background

Sengoku began as a low-ranking Marine and rose through decades of achievement, political support, and personal effort to become Fleet Admiral. His experience at every level of the organization informs his view that even low-ranking Marines are a vital collective force. 115

He operates from Marine Headquarters at Marineford, where he works closely with Vice Admiral Crane on matters involving the World Government, internal Marine affairs, and high-level deployments. 50 53

Appearance

Sengoku is a middle-aged man with an imposing expression, a small braid beneath his beard, and frog-shaped glasses. 7 181

• Keeps a small sheep on his desk; it eats documents he discards. 7
• Usually works from the Fleet Admiral’s office at Marine Headquarters. 7 50

Personality

Sengoku is strategic, institution-focused, and deeply invested in the Marines’ long-term survival. He carefully restricts sensitive information when he believes disclosure could draw the attention of the Four Emperors or World Government, especially concerning exceptional young assets such as Ye Feng and Avril. 122

His pragmatism can become ruthless. When Crane presents a list of more than five hundred people considered a threat to the Marines’ future, Sengoku orders Kizaru to eliminate everyone on it within three days and leave no trace. 53

Despite his rank, Sengoku understands the political value and military importance of ordinary Marines. He deliberately acknowledges lower-ranking personnel, believing their united support is necessary to stabilize the organization. 115

He has a volatile but longstanding camaraderie with Garp. Their arguments frequently escalate toward violence, though Crane can force both men to stand down. 51 115

Abilities & Skills

Armament Haki

Sengoku can coat his fists in Armament Haki, which he prepared to use during a confrontation with Garp. 51

• Was ready to clash directly with Garp before Crane interrupted them. 51

Strategic Command

As Fleet Admiral, Sengoku directs Marine personnel, covert operations, intelligence matters, and major deployments.

• Ordered Verne to detain Ye Feng and Avril should they return after learning of their extraordinary swordsmanship and Haki. 8
• Ordered Kizaru to secretly eliminate every person on Crane’s list without leaving evidence. 53
• Dispatched Major Ross to investigate Vice Admiral Roll and execute him if evidence of wrongdoing was found. 171
• Sent Kizaru to the New World after receiving intelligence on the escalating conflict between the Big Mom and Beasts Pirates. 173
• Convened high-level meetings in response to World Government orders concerning Ohara and Jaguar D. Saul. 181

Personnel Assessment

Sengoku closely tracks promising Marines and skilled swordsmen.

• Immediately recognized Ye Feng and Avril as assets who could shape the Marines’ future. 51 116
• Identified Marine Headquarters’ principal sword experts for Ye Feng, including Momonga, Bastille, Onigumo, Peach Rabbit, and Kizaru. 81
• Arranged for Kizaru to instruct Ye Feng in swordsmanship. 83
• Monitored Ye Feng’s Six Powers training and classified his exceptional records as a Marine secret. 153 157

Relationships

• Monkey D. Garp — Fellow Marine veteran, frequent rival, and close comrade. Their arguments often turn into near-fights, but Sengoku also helps manage crises involving Garp’s grandson, Ye Feng. 51 115 143
• Vice Admiral Crane — Chief Staff Officer and trusted strategic partner. Crane advises Sengoku on covert killings, secrecy, and how to handle controversial World Government policy. 53 300
• Ye Feng — Sengoku views him as an extraordinary future Marine swordsman and takes an active interest in his training, safety, and political vulnerability. 51 82 143 232
• Avril — Alongside Ye Feng, Sengoku regards her as a future Great Swordsman and a cornerstone of the Marines’ next generation. 51 116 121
• Kizaru — Admiral under Sengoku’s command. Sengoku entrusts him with both covert eliminations and Ye Feng’s swordsmanship instruction. 53 83
• Zephyr — Longtime Marine comrade who attends Sengoku’s highest-level meetings. 115 116
• Jaguar D. Saul — Sengoku ordered Saul to send Nico Olvia to Impel Down; Saul instead released her and helped her escape. 181
• The Five Elders — Their orders repeatedly place Sengoku in difficult positions, including Ye Feng’s appointment as CP9 commander and the Shichibukai Plan. 232 301

Story Role

Discovery of Ye Feng and Avril

Vice Admiral Verne’s report that two children possessed Sword King-level strength shocks Sengoku. After confirming their ages and abilities, Sengoku orders that they be detained if they return. 7 8

When Ye Feng later reaches Marineford, Sengoku is impressed by his and Avril’s potential. He predicts they can attain Great Swordsman rank before adulthood and imagines a Marine era capable of suppressing piracy. 51

“In the future, our Marines will have two Great Swordsmen!!!” 116

Protecting the Marines’ Future

Sengoku treats Ye Feng and Avril’s existence as a strategic secret. He warns high-ranking Marines that exposure could provoke intervention from the Four Emperors or the World Government. 122

When Ye Feng disappears from Marineford, Sengoku mobilizes Marine Headquarters and convenes an emergency high-level meeting after Garp’s Observation Haki fails to locate him. 143

World Government Orders

Sengoku enforces World Government directives even when they create severe consequences. He orders Saul to imprison Olvia and later convenes the Marines after receiving the order to destroy Ohara and capture Saul and Olvia. 181

He is deeply suspicious of the Five Elders’ decision to appoint Ye Feng as CP9’s commander, believing they intend to control or remove a dangerous uncertain factor. 232 233

Shichibukai Plan

Sengoku strongly opposes the Shichibukai Plan, considering it disgraceful for the Marines to protect a pirate who killed Marines and injured an Admiral. 300 301

At the same time, he receives the World Government’s notice that Ye Feng has been released and transferred back to the Marines, easing Garp’s fears that Ye Feng might abandon the organization as Dragon did. 300 301

Trivia

• Garp repeatedly kicks open Sengoku’s office door, and Sengoku can identify the culprit immediately. 50 72
• Sengoku and Garp once bet a month’s worth of donuts on how quickly Ye Feng would master the Six Powers; both underestimated him. 156 157
