Marineford — the island that served as the Navy's headquarters — was divided into two distinct halves.The front side held all the naval facilities and military docks, while the rear side was a living area for civilians, complete with a public harbor.
Most of the residents in that area were families of marines or people connected to the Navy, running small shops or local businesses.There were also other kinds of people — for instance, merchants who made their living at sea.
As a result, the civilian harbor was always full of trading ships, and many warehouses had been built nearby.
After traveling swiftly to Marineford using the Ephemeral Body Technique, Black Zetsu came ashore near the far-left side of those warehouses, by the foot of a small hill that bordered the area.
The side of the hill facing the sea was a near-vertical 70-degree cliff of jagged rock. Black Zetsu stepped across the white stone shore polished smooth by the waves, beyond which lay an uneven field of reef and boulder.
A golden flash streaked across the air, and in an instant, it materialized into a tall, thin man wearing a yellow-and-white pinstriped suit.
"Hmm? You're the one providing us with the substitutes?"The man who relied on speed for everything — Borsalino, the Yellow Ape — had indeed arrived first.
"That's right."Black Zetsu nodded. The white half of his body writhed briefly, and a moment later, it split off, forming a separate White Zetsu.
"Touch him," Black Zetsu instructed, pointing at the newly formed White Zetsu.
Thanks to system adjustments, group members could still use their skills normally, even in this alternate world.
Borsalino eyed the strange, pale humanoid suspiciously. He didn't move right away — clearly wary of some trick.After a short pause, he finally reached out and touched White Zetsu's skin.
The moment his fingers made contact, a sharp sting pricked his fingertip — like being jabbed by a needle. He immediately pulled his hand back.
At the same time, White Zetsu's entire body began to ripple and writhe. Its figure stretched and shifted, gradually taking on Borsalino's appearance. About ten seconds later, a second Borsalino stood before them.
"Waa~ So impressive, huh~?"The original Borsalino's tone and expression were the same as ever — exaggerated, drawn-out, dripping with mockery.It was impossible to tell whether he was genuinely impressed or simply being sarcastic.
Black Zetsu didn't care either way. He wasn't here to argue — only to make money. Clients could say whatever they wanted; as long as they paid, it was fine.
About a minute later, while Borsalino studied his doppelgänger like someone playing a spot-the-difference game, Aokiji Kuzan arrived, pedaling his bicycle across the sea.
"So, which one do you think is real?" ×2
The two Borsalinos turned to Kuzan, playing the classic "true and fake" guessing game.
Kuzan, still holding his bicycle with one hand, squinted for a while and then pointed to the one on the right."You're the real one."
The real Borsalino clapped lightly."Congratulations~ You got it right! How'd you tell?"
The two were absolutely identical — not a single difference could be seen. How had Kuzan figured it out?
"Emmm…" Kuzan adjusted his words. "Your smile has… a certain flair. Not many could imitate that."
"Really now?"Borsalino rubbed his face thoughtfully and turned to look at his duplicate. The imitation pursed its lips into a smile — awkward, stiff, and weirdly off.
Emmmm…
Borsalino went silent.
One after another, more people arrived at the scene.Though their movements drew some attention from the locals, no one thought much of it — the people here were used to seeing strange things.
After finishing all forty-five substitutes, Black Zetsu received a single day's payment — forty-five times two hundred, totaling nine thousand.How long the disguises would last depended entirely on when the group decided to assassinate the Celestial Dragons.
Hearing this, Black Zetsu nodded in understanding.
The Uchiha group was still busy ganging up on the Seven Warlords, so they'd need some time before heading to Mary Geoise.
Which meant…
As long as he didn't make a move against the Celestial Dragons himself, he could keep charging for at least one more day.
Black Zetsu thought it over.Fine — he wouldn't act yet. Better to prepare a bit more first.
As he slowly sank back into the stone, he said, "White Zetsu's combat strength is quite low. Be cautious."
Even though he wanted to make as much profit as possible, Black Zetsu still gave a fair warning. Business reputation mattered, after all.
"Thanks for the reminder," Sengoku said. "The substitutes won't need to fight. Their job is just to stay in the room, eat, drink, and look the part. I don't need them to last long."
Sengoku had already arranged everything.If anything unexpected happened, there were people ready to handle it. The substitutes only needed to sit quietly for a day or two — no fighting required.
Once the Celestial Dragons were dead or the Navy launched a sneak attack on a Yonko crew, their role would be complete.
Black Zetsu didn't reply. He simply melted completely into the rocks and disappeared.
Sengoku withdrew his gaze from where Black Zetsu had vanished and looked out to sea.The gull-shaped mark on the back of his hand gleamed faintly, and a metallic aircraft suddenly rose from beneath the waves.
The gathered admirals and officers reacted with a mix of curiosity and astonishment.
"That's Dr. Vegapunk's latest invention — an amphibious fighter jet," Sengoku explained with a slightly complicated expression.
Honestly, even he hadn't expected Vegapunk to be this insane.First he built a Gundam, and now a fighter jet.The man was producing at a terrifying rate… cough, cough.
Vegapunk: ╮( ̄▽ ̄)╭You think I lack technology? Or knowledge?
No — what I lack is inspiration!
And manga gives me inspiration!Now then… what should I build next?
After hearing Sengoku's explanation, everyone's expressions returned to normal.Since it was Vegapunk, that made sense—
Wait, what sense?!
That's not what we wanted to ask!
Sengoku-san, how did you just make that jet appear out of nowhere?!
A chorus of silent inner screams echoed through the cabin.
"Let's go."
Sengoku took the lead, stepping into the cockpit and sitting at the controls. The others filed in one after another, taking their seats.
"Fasten your seatbelts," Sengoku's voice echoed inside.
Garp heard him and obediently buckled up, the others following suit.
"Alright then…"
The aircraft's controls were remarkably simple — one steering wheel, one throttle, one brake.
"Launch!!"
He stomped the accelerator.The fighter slowly sank beneath the sea's surface.Once it reached a certain depth, a low hum filled the cabin as torrents of seawater were sucked into the craft.
Conversion… propulsion…
With a sharp whoosh, the fighter tore through the water like an arrow loosed from a bowstring.Fish and shrimp in its path were instantly pulverized, and even Sea Kings were sliced cleanly in half.
Yet the jet remained completely undamaged — solid, durable, and efficient.
The intense acceleration slammed everyone back into their seats, and Borsalino couldn't help but mutter inwardly:
"This speed's… a bit much, huh~…"
Sengoku at the controls was thinking the same thing.
A second ago, he had spotted a Sea King and was just about to turn to avoid it — but before he could, the creature had already been neatly bisected.
"Well, we're far enough from Marineford now," he thought. "Might as well head into the sky."
Flying would at least eliminate the risk of accidentally ramming into an island.
