The boat was on fire.
Not seriously on fire — not yet — but a section of the mast was burning with the particular enthusiasm of wood that had been hit by something very hot and hadn't decided how far to take it. Below the fire, on the small deck of what was genuinely the most battered boat Goku had seen since arriving in this world, a boy in a straw hat was laughing.
Not nervous laughter. Not relieved laughter. The pure, uncomplicated laughter of someone who was having exactly the kind of morning they'd hoped for.
The Marine ship was circling them, cannons loaded, keeping its distance. Goku could see why: the boy had already taken one cannonball to the chest — he'd watched it happen from two hundred meters up, seen the ball hit and the boy stretch backward with the impact and then snap forward like a rubber band — and was still standing. Still grinning. Apparently uninjured in any way that mattered to him.
Beside the boy, a green-haired man had three swords out and was watching the Marine ship with the flat, patient attention of someone calculating angles.
There they are.
Goku descended.
✦ ✦ ✦
Luffy's boat — East Blue — Morning
He landed on the bow.
The green-haired man had three swords pointed at him before his feet touched the wood.
Fast. Very fast — not fast by Goku's standards, but fast by every other standard he'd encountered since arriving. The draw had been clean and economical, no wasted motion, the kind of speed that came from ten thousand repetitions until the movement lived in the body instead of the mind.
Goku raised both hands, palms out.
"I'm not a Marine," he said.
The grey eyes above the blades moved across him — the orange gi, the empty hands, the complete absence of a Navy uniform or a weapon — and the calculation happened fast. The swords didn't lower, but the angle changed. From kill to wait.
"Then what are you?" the swordsman said.
"Goku. I've been following you two since Shells Town."
A beat.
"Following us," Zoro repeated. The flatness in his voice was not anger — it was the sound of someone deciding whether this was a problem.
"Not in a bad way." Goku glanced at the burning mast. "I heard about you from Cobi. And from a merchant ship your friend helped two days ago." He looked back at Zoro. "Also your boat is on fire."
"I know."
"Should we —"
"Luffy's handling it."
Goku looked at the boy with the straw hat, who was now standing on the railing, pointing at the Marine ship across the water, shouting something that carried the word 'stupid' three times in the same sentence. He did not appear to be handling the fire.
"Okay," Goku said.
He looked back at Zoro. Zoro looked at him. The swords were still out but the calculation in the grey eyes had moved past threat assessment into something more complicated — the specific look of a person encountering something they don't have a category for yet.
"You flew," Zoro said.
"Yes."
"From the sky."
"That's generally where flying happens."
A pause. The swords lowered — not sheathed, but lowered. "No Devil Fruit," Zoro said. It wasn't a question.
"No. Something different." Goku nodded at the Marine ship. "Can I help with that?"
"We don't need —"
"OI!"
Both of them turned.
The boy with the straw hat had apparently noticed Goku for the first time. He was standing on the railing with one hand gripping the rigging, leaning forward, staring across the deck with an expression of total, delighted focus — the look of someone who had just spotted something interesting in a room full of interesting things and immediately made it the most important thing in the room.
"YOU FLEW!" he shouted. "I SAW YOU! YOU CAME FROM THE SKY!"
"Yes," Goku said.
"THAT'S AMAZING!" He launched himself off the railing — literally launched, rubber legs stretching, covering the length of the deck in one ridiculous bound — and landed in front of Goku with the impact of someone who had never in his life considered that landing hard might be unpleasant for the landing surface.
Up close, the grin was even more direct than it had been on the poster. No performance in it. No self-consciousness. Just — pure, unfiltered interest, pointed at Goku like a beam of light.
"How?" Luffy demanded. "No wings. No balloon. How?"
"Energy," Goku said. "I'll explain later. Your boat is —"
"Can you teach me?"
"Probably not. It's —"
"Are you a pirate?"
"No."
"Do you want to be?"
"I —" Goku stopped. Processed this. "Your boat is on fire."
Luffy looked at the mast. Looked back at Goku. Clearly ranked these two facts in order of importance.
"Zoro'll get it," he said.
"I'm not getting it," Zoro said, from behind them, not looking up from the Marine ship.
Goku exhaled. He turned, found a bucket lashed to the side of the boat, filled it from the sea in about four seconds, and put the fire out.
Silence.
"...He got it," Luffy said.
✦ ✦ ✦
The deck — seconds later
The Marine ship had stopped circling.
Goku felt it before he saw it — that precise, disciplined signature he'd tracked from two hundred meters up, now moving. Not the ship. The person.
Someone had jumped.
Not jumped toward the boat — jumped away from the ship entirely, straight up, the kind of vertical launch that required either a Devil Fruit or a level of physical ability that had left ordinary human limits somewhere far behind. The signature rose, peaked, and then dropped — directly toward them.
Goku looked up.
A man in a white Marine coat was falling toward their boat like a dropped stone, one hand on a jitte — a two-pronged weapon, heavy, Sea Prism Stone tip catching the light — and the Haki around him was compressed so tightly it had become visible: a faint distortion in the air, the way heat bent light above summer asphalt.
"Move," Goku said.
He didn't wait. He stepped forward, off the bow, back into the air, and met the Marine Captain on the way down.
The impact was significant.
The Marine — broad-shouldered, white hair, the particular face of someone who had looked at the world for a long time and decided it was mostly disappointing — pulled his strike at the last second. Not from hesitation. From reassessment: he'd aimed at the boat and something had gotten between him and the boat, and now he was in the air with no leverage and a man in orange who was hovering without apparent effort and looking at him with focused, thoughtful attention.
"You're not one of them," the Marine said.
"No," Goku agreed. "Captain Smoker?"
The white-haired man's eyes narrowed slightly. "You know my name."
"Someone mentioned you. Said you were stationed at Loguetown." Goku glanced down at the boat, where Luffy and Zoro were watching from the deck. Then back at Smoker. "You're a long way from Loguetown."
"Straw Hat crossed into my jurisdiction." Smoker's voice was flat as a ruled line. "Step aside."
"I'm not in your way," Goku said. "I'm just in this particular piece of air."
Something moved in Smoker's expression — not quite frustration, not quite the cold calculation of a man deciding his next move. Something more like the look of a person whose day had already been complicated and had just gotten more so.
"You can fly without a Devil Fruit," Smoker said.
"Yes."
"And you just intercept strangers in midair."
"I like to understand situations before they finish happening." Goku met the Marine captain's gaze directly — not aggressively, but without looking away. "You're strong. Genuinely strong, not just trained — there's a difference, and you've got both. That Haki around you is the tightest I've felt since I got here."
A pause.
"Got here," Smoker repeated.
"This world. The East Blue." Goku said it plainly. "I'm from somewhere else. I'm still learning the geography."
Smoker looked at him for a long moment. The jitte hadn't moved. The Haki was still compressed, still ready. But the calculation in his eyes had shifted to a different kind of assessment — not tactical. Something more like the way experienced people looked at things they recognized as significant without knowing exactly why yet.
"What do you want?" Smoker said.
"Right now? For you to let that boat go." Goku glanced at the small vessel below them. "They're not doing anything worth this much attention today."
"Monkey D. Luffy has a bounty —"
"Thirty million. I know. He'll probably have more later." Something in Goku's voice shifted — not harder, but more certain. "But not because of today. Today's too small for whatever he's actually going to become."
The sea moved beneath them. The Marine ship held its position, waiting for orders that weren't coming.
Smoker stared at the man floating in the air in front of him who had just predicted the future of a pirate's bounty with the casual confidence of someone reading tomorrow's weather.
"You're certain of that," Smoker said.
"I can feel what people are going to become," Goku said, simply. "Not always, not precisely. But the ones who are pointed at something real — yes. I can feel it. That boy is pointed at something very real."
Another silence. Longer this time.
Then Smoker turned in the air, descended back toward his ship, landed on the deck without looking back.
"Next time," he said, loud enough to carry across the water, "I won't be asking."
Goku watched the Marine ship begin to turn.
"Okay," he said, to the open air.
✦ ✦ ✦
The boat — minutes later
He landed back on the deck.
Luffy was sitting on the bow with his legs hanging over the water, watching the Marine ship shrink toward the horizon. His expression had moved past delighted into something more concentrated — the specific face of a person filing information for later use.
Zoro was leaning against the mast — the formerly burning one — with his arms crossed and his eyes closed, apparently asleep or doing a very committed impression of it.
Neither of them said anything for a moment.
Then Luffy turned and looked at Goku with the full force of his attention.
"You talked him down," he said.
"For now."
"How?"
Goku thought about it. "I told him the truth. That you're going to be worth more attention than he was giving you today."
Luffy processed this.
Then he grinned — the full version, the one from the poster — and it was, Goku thought, exactly what he'd expected and somehow still more than he'd been prepared for. There was nothing behind it. No calculation, no performance, no awareness of how it looked. Just a person, being entirely themselves, all at once.
"You're not a pirate," Luffy said. "And you're not a Marine. What are you?"
"A fighter. From somewhere else."
"Somewhere else like — another island?"
"Another world, actually."
A beat.
"Cool," Luffy said, with zero hesitation.
From behind them, without opening his eyes, Zoro said: "You flew here from another world."
"I fell, technically. I'm working on the getting-back part."
"Can you fight?" Luffy asked.
"Yes."
"Are you strong?"
Goku considered being diplomatic about this. "Yes."
Luffy pointed at him. "Join my crew."
"I —" Goku paused. "You just met me thirty minutes ago."
"I know. Are you joining?"
"I don't think I should join a pirate crew."
"Why?"
"I'm not a pirate."
"So?"
Goku opened his mouth. Closed it. Looked at the boy who had just survived a cannonball to the chest while laughing and was now trying to recruit a stranger from another dimension into his two-person crew with complete and unironic confidence.
He thought about what he'd told himself. This isn't your story. Observe. Don't interfere.
He thought about Smoker's ship on the horizon.
He thought about what the first mate had said: Arlong. Nami. A woman buying her village back from a fishman pirate with years of stolen money. Things moving in this sea that were going to hit this boat before it reached the Grand Line.
"I'm not joining your crew," he said.
Luffy looked at him.
"But I'll sail with you for a while," Goku said. "Until I figure out where I'm going."
A pause.
"That's the same thing," Luffy said.
"It's really not."
"It's the same thing."
From the mast, Zoro made a sound that was not quite a laugh but was in that neighborhood.
Goku looked at the horizon — east, the direction everything kept pointing him. The sea was very wide and the boat was very small and somewhere ahead of them, the Grand Line was waiting like a question nobody had fully answered yet.
"Fine," he said. "For a while."
Luffy pumped his fist.
"OI ZORO! We have a nakama!"
"He said he's not joining," Zoro said, eyes still closed.
"He's totally joining."
"He said —"
"He's. Totally. Joining."
Goku sat down on the deck, leaned against the bow, and looked at the sky. It was very blue. The boat was very battered. The mast still smelled faintly of smoke.
He thought: I was going to observe from a distance.
He thought: Chi-Chi is going to be so angry when I get home.
He thought: this is the good kind of trouble.
The boat sailed east.
