Chapter 678

Panicking at the gas creeping toward the gap, the G-5 Marines hurriedly board up the broken shutter and shut it out. Brook detaches his spirit to scout outside, finding the entire landscape encased in Shinokuni's ashen shell and confirming that anyone caught out there is finished. The relieved standoff dissolves as the Marines briefly aim their guns at the intruders.

At Nami's insistence, Law swaps her and Sanji back into their own bodies, to Sanji's quiet despair. Law then briefs everyone: the gas traps them inside, but a single route to the sea exists through a door labeled Building R-66, and they have two hours before he does something dangerous. The group divides up the work and scatters.

Kin'emon and Zoro head a party hunting for the captured children, Smoker resolves to face Vergo alone and puts Tashigi in charge of leading the Marines to the exit, and Luffy charges after Caesar. Warned by Zoro to take the enemy seriously after his earlier loss, Luffy accepts the lesson. When a squad of Caesar's men opens fire, he hooks his legs around the railing, swings beneath the walkway, and mows them all down with a whirling new attack he calls Gomu Gomu no UFO.

Law confirms the lab's hidden sea exit and grants the two hour window before his risky move. Smoker's plan to fight Vergo solo is set, with Tashigi ordered to shepherd the troops and kidnapped children to commandeer Vergo's tanker at the harbor. Luffy's Gomu Gomu no UFO makes its first appearance. The cover continues Caribou's story, with Jinbe hauling him off Fish-Man Island.
