The ten-day deadline has arrived, and all eyes are on Naval Headquarters. The world is eager to see what changes will come from the Seven Warlords of the Sea conference and how it will impact the seas. Whether the Marines will make a major move or if they will have to confront the Four Emperors.
The port of Marine Vatican is in chaos as countless Marine soldiers gather to catch a glimpse of the empress. Amidst the noise and commotion, Hancock frowns and demands for silence using her powers to turn Marines into stone. However, her sisters, Boya Sandsonia, express concern about their actions in Naval Headquarters.
Ignoring their concerns, Hancock continues to indulge in her beauty and uses her powers to captivate even more Marines. Meanwhile, a group of pirates led by Doflamingo arrives at the harbor. Doflamingo asks Hancock what she is holding onto and provokes her, causing her to become angry.
Lieutenant General Mu Feng's adjutant, Guy Er, intervenes and reminds them that they are in Naval Headquarters and must behave. He leads Hancock and Doflamingo away while many Marines still remain on the pier, excitedly recognizing other members of the Seven Warlords of the Sea.
Finally, the last member, "Eagle Eye" Mihawk, arrives in his coffin-like boat, completing the assembly of the Seven Warlords of the Sea.
Inside the Marine round table meeting room, the atmosphere is tense. Doflamingo, unbothered by the situation, eats an apple and questions why Hawkeye is present. Hawkeye's response leaves Doflamingo speechless, and the room falls into an eerie silence for three hours.
Mu Feng enters the room and dismisses the Marine soldiers guarding the room. He closes the door, ensuring the conversation remains confidential. Doflamingo immediately demands to know the whereabouts of Diamante and demands his return.
Mu Feng reveals that Diamante is still alive, leaving Doflamingo in shock and anger. The tension escalates when Mu Feng's Conqueror's Haki is unleashed, overpowering everyone in the room except for Doflamingo, Hancock, and Mihawk. Crocodile, in particular, struggles to remain conscious.
Mu Feng's Conqueror's Haki is at an advanced level, and its impact is compared to a tsunami. It is noted that Mu Feng's Conqueror's Haki is among the most powerful in the world, comparable to renowned individuals like Garp, Rayleigh, and Shanks. The fact that such power is possessed by a 17-year-old boy astonishes Doflamingo and the others.
