Background / History

Kong selected Sengoku to succeed him as Fleet Admiral while the Marines prepared to suppress the consequences of the Pirate King's legacy and the One Piece. 5

During the transition of power, Sengoku proposed promoting Sakazuki, Borsalino, and Kuzan to Admiral. The proposal strengthened Marine forces in the Grand Line while ensuring the three officers owed him political support. 41

At the Reverie, Sengoku secured Marine oversight of the newly established Shichibukai system and a 15% budget increase. The funding supported equipment, research, salaries, and personnel benefits. 103

He remained heavily involved in major Marine decisions, including the response to Ace's rise, the Wano crisis, and plans to provoke conflict among the Four Emperors. His caution often clashed with Mo Xingchen's more aggressive proposals. 170 171 200 218

During the Summit War, Sengoku rallied the Marines publicly and negotiated directly with Whitebeard after the pirate approached Marineford alone. 258 259

At age 77, Sengoku announced his retirement while the Marines were strong and piracy had declined. Having seen Kong's retirement repeatedly delayed by crises, he chose to step down before a similar reversal could occur; he later recommended Admiral Tian Shu as his successor to the Gorosei. 273 277

Despite retirement, Sengoku later joined Garp and other powerful figures against the Divine Knights, transforming into his Great Buddha form during the battle at Mary Geoise. 319 320

Appearance

Sengoku can assume a colossal golden Great Buddha form. In his ordinary form, he is shown with white hair, though he dyes it black to maintain a more youthful Fleet Admiral image. 170 320

• Transforms into a golden giant Buddha in combat. 320
• Was caught by Tsuru with uneven black-and-white hair while dyeing it. 170

Personality

Sengoku is politically astute and highly conscious of the Marines' institutional strength. He uses promotions to build support, seeks funding and authority for the organization, and considers long-term stability before acting. 41 103 200

He is also notably cautious, particularly where Mo Xingchen's actions could provoke the Four Emperors or the World Government. Even so, he eventually accepts Tsuru's judgment and trusts Mo Xingchen to travel to the latter half of the Grand Line. 218

In personal interactions, Sengoku is quick-tempered and strict about official decorum, yet repeatedly engages in familiar quarrels with Garp and Mo Xingchen. He also has a vain streak, evidenced by his attempt to conceal his white hair. 146 170 197
