Grand Line — Two Years After the Paramount War, Weatheria.
Far above the sea—where even birds rarely dared to fly, a cluster of artificial clouds drifted silently across the sky.
This was Weatheria.
A moving sky island, guided by controlled wind currents, where old men in robes studied the climate like it was a sacred religion—and where one thief had turned their entire world upside down.
Soft winds brushed across the floating platforms. Balloon-like plants swayed gently, and small spherical clouds drifted lazily through the air.
And then—
“WAAAAAAAAAH!! NAMI-SWAAAAAAAN!!”
“DON’T LEAVE US!! THE BAROMETRIC PRESSURE WILL NEVER BE THE SAME WITHOUT YOU!!”
“WHO WILL YELL AT US WHEN WE OVERCHARGE FOR CLOUDS?!”
“YOU SHOULD’VE THOUGHT ABOUT THAT BEFORE TRYING TO SELL ME AIR!!”
At the center of the chaos stood Nami, veins popping on her forehead, Clima-Tact already raised.
“AND WHAT WAS THAT ‘EMOTIONAL SUPPORT TAX’ HUH?!”
“IT WAS SCIENCE!!”
“IT WAS A SCAM!!”
BONK.
A short distance away—
Leaning against a curved railing, completely detached from the emotional storm behind him—stood a young man with messy brown hair and lazy golden eyes.
Train Heartnet let out a quiet yawn.
“…Man, these guys are so loud.”
A small weather sphere floated toward him.
Pop.
A tiny thundercloud formed.
ZAP.
“…Ow.”
He scratched his head, unimpressed.
“…Yeah, this place is kinda annoying.”
⸻
“OI!!”
Nami spun instantly.
“Don’t insult Weatheria!! This place made me WAY stronger!!”
Train tilted his head slightly.
“…Yeah. Lightning tricks. Pretty cool.”
“PRETTY—?!”
She swung the Clima-Tact.
Train leaned back just enough for it to miss.
“…You almost hit me.”
“I MEANT TO!!”
⸻
A breeze passed between them.
The chaos behind them faded slightly.
Below the clouds, the ocean stretched endlessly.
For a moment—
it was quiet.
⸻
“…So,” Train said, glancing ahead. “…Today, huh?”
Nami didn’t answer immediately.
Her arms crossed slowly.
“…Yeah.”
No yelling. No sarcasm. Just that.
⸻
Behind them—
“WAAAAAAAH NAMI-SWAAAAAAN!!”
“PLEASE VISIT US AGAIN!!”
“AND SEND MONEY!!”
“WHY WOULD I SEND YOU MONEY?!”
“FOR SCIENCE!!”
“STOP SAYING THAT!!”
⸻
Nami exhaled sharply, snapping back to her usual self.
“Listen up!! I’ll send weather data if I feel like it—but you’re not getting a single berry!!”
“HEARTLESS!!”
“CRUEL!!”
“PIRATE!!”
“I AM A PIRATE, YOU IDIOTS!!”
⸻
Train pushed himself off the railing, stretching slightly.
“…You ready?”
Nami adjusted her bag.
“…Obviously.”
A pause.
“…You don’t have to come, you know.”
Train shrugged.
“…Got nothing else to do.”
Then, after a beat—
“…Also, you’d probably get lost.”
⸻
Silence.
Wind.
⸻
“WHO GETS LOST, YOU STRAY CAT?!”
WHACK.
⸻
Minutes later—
A small cloud vessel drifted away from Weatheria, slowly descending through layers of white sky.
Behind them, the old men waved dramatically, tears flying in every direction.
“NAMI-SWAAAAAAN!!”
“DON’T FORGET YOUR STUDIES!!”
“AND YOUR DEBT!!”
“I DON’T HAVE A DEBT!!”
⸻
The clouds began to part.
Blue expanded beneath them.
The vast ocean of the Grand Line came into view.
⸻
At the front of the vessel stood Nami.
Hair flowing.
Eyes sharp.
Focused.
⸻
At the back—
Train sat casually, one leg dangling off the edge like none of this concerned him.
“…So,” he said lazily. “Where are we going?”
⸻
Without turning—
“Sabaody Archipelago.”
⸻
Train blinked.
“…Sounds far.”
“It is.”
“…You got a plan?”
⸻
A small smirk formed on Nami’s face.
“…Of course.”
She turned slightly.
“…I’m navigating.”
⸻
A pause.
Wind rushing.
Clouds drifting.
⸻
Train leaned back again.
“…Yeah.”
“…We’re definitely getting lost.”
⸻
“SHUT UPPPP!!”
⸻
Above them, Weatheria drifted further away. Below them, the Grand Line stretched endlessly forward.
And somewhere far ahead—
their next destination was waiting.
