He'd been flying for two hours and there was no trail.
Not a boat in the water. Not a disturbance on the surface. Not even the faint warmth of two life signatures pointing him in a direction. Just ocean — enormous, indifferent, going on and on in every shade of blue until it met the sky.
Goku stopped midair and thought about this.
Back home, finding someone was simple: feel their Ki, lock on, move. Even across dimensions, even through time, he could usually find a thread and pull it. But this world didn't work that way. Whatever the people here used instead of Ki — Haki, Devil Fruit power, the simple heat of being alive — it didn't broadcast the same way. It was quieter. More compressed. Like everyone had learned, at some point, to take up less space in the universe.
He needed a better method.
He closed his eyes.
Cobi had said: Haki is will. Your spirit, made physical. The stronger your conviction, the further it reaches.
Goku thought about the teacup sliding across the table. He thought about that muscle — the unfamiliar one, the one he'd found by accident when he was looking for something else. He reached for it again, but this time instead of pushing, he spread.
Thin. Wide. Like dropping a sheet of paper onto water and watching it settle.
He felt the sea.
Not Ki — something adjacent. Hundreds of small warmths, scattered across the water: fish, birds, people on boats, things in the deep he didn't have names for. And underneath all of it, a texture — the specific texture of a world that ran on different rules than his, that had its own logic, its own physics of power, its own idea of what strength meant.
He held it. Breathed. Let it map itself.
And there — northeast, maybe forty kilometers — something brighter than the background. Two somethings. One with the particular quality he recognized from the wanted poster: loud, open, completely unbothered. The other compressed and pointed, like a blade left in its sheath.
Found them.
He opened his eyes and flew northeast.
And that was when he heard the cannon.
✦ ✦ ✦
East Blue — Open Water — Morning
The sound reached him before the smoke did — the deep, flat crack of a naval cannon, followed three seconds later by the groan of stressed wood. He banked without thinking, dropping altitude, and saw it below him: a merchant vessel, mid-sized, listing slightly to port. And circling it, patient as a shark, a pirate ship with black sails and a ram on the bow that had clearly already been used once this morning.
He counted the signatures on the pirate ship. Thirty-something. All of them hot with the kind of excitement that wanted to be violence.
On the merchant vessel: fewer. Scared. Not fighters.
He did the math in about one second.
Then he looked east — toward that bright, loud warmth that was Luffy's signature, forty kilometers away and moving.
He looked back at the listing ship.
He descended.
The pirate ship's deck was crowded when he landed on the bow railing — same easy balance as stepping off a curb — and the nearest five men spun toward him with weapons half-drawn before their brains fully caught up with what they were seeing.
"Hey," Goku said. "Leave them alone."
Nobody moved.
At the back of the deck, behind his crew, a man in a feathered coat — the captain, clearly, the kind of person who wore feathers to make a point — tilted his head.
"Who," he said, "are you?"
"Goku. I'm passing through." He kept his voice level. Not aggressive — he wasn't angry, just certain. "I'm going to ask you once to turn around and leave that ship alone."
The captain looked at the man standing on his bow railing, apparently having arrived from the sky, with no weapon and no crew and no ship.
He laughed.
"Once," he repeated. "Bold." He snapped his fingers. "Kill him. Then finish the job."
The crew moved.
Goku exhaled slowly.
He'd been thinking about what he learned last night — about how this world's fighters worked, how they used their bodies, what Haki looked like in practice. He wanted to test something.
He let the first man's sword come in and, instead of catching it with his fingers the way he had in Roca Port, he coated his forearm. The same inward compression. Dense. Layered.
The blade hit the Armament-coated arm and snapped.
Not bent. Not deflected.
Snapped.
Clean, like hitting iron.
The pirate stared at the half-sword in his hand. Goku looked at his own forearm with genuine interest — the darkness had come and gone in under a second, but he'd felt it clearly. The texture was already becoming familiar. A week of practice and it would be natural.
"That worked," he said to himself, pleased.
The pirate dropped what was left of his sword and ran.
What followed was fast. Not because Goku was trying to be fast — he was actually trying to be slow, to feel how the technique integrated with basic movement, whether it affected his footwork, how the compression held under impact. Clinical. Methodical.
For the pirates on the receiving end it still lasted less than ninety seconds.
When it was over, thirty-one crew members were sitting or lying on the deck in various states of consciousness, and the captain in the feathered coat was standing against his own mast with Goku's hand flat against the wood beside his head, not quite touching him, just — there.
"Turn around," Goku said. Still not angry. Still certain. "Go somewhere else. Don't bother ships that can't fight back."
The captain — who had a bounty of eight million Beri, who had not lost a fight in four years, who had once made a Navy Lieutenant cry — nodded very fast.
Goku stepped back.
"Good."
He walked to the railing, stepped off, and flew.
✦ ✦ ✦
The merchant vessel — minutes later
He landed on the merchant ship's deck because someone on it was injured and he wanted to make sure they were alright, and because the ship was still listing and he thought there might be something structural he could help with.
The crew — eight of them, middle-aged, the kind of people who had spent their lives moving cargo between islands and wanted nothing more complicated than fair weather and honest port fees — stared at him with the specific expression of people who had just watched something happen and hadn't yet decided how to feel about it.
"Is everyone okay?" Goku asked.
A woman with a bandage around her forearm — the first mate, by the look of her — pointed at his arm.
"Your arm turned black," she said.
"Haki." He looked at it. "Still working on the control. Did the cannon hit anything below the waterline?"
She blinked. Then, apparently deciding that a man who turned his arm black to block swords and then asked about structural damage was a type of person she could work with, she nodded.
"Grazed the hull. We're not sinking but we'll take on water if we push speed."
"I can look at it if you want."
"You're a shipwright?"
"No, but I'm good with my hands."
She gave him the same look Cobi had given him when the teacup moved — the look of someone updating a model mid-conversation. "...Follow me."
The damage was below the waterline, which meant someone had to go under. Goku volunteered, dove, found the crack — a hairline, eighteen centimeters, manageable — and held pressure against it from the outside while two crew members sealed it from the inside. Twenty minutes. Simple.
When he came back up, the first mate handed him a towel and a cup of coffee.
He'd been offered food or drink after every single fight since he arrived. He was beginning to understand that this was how people here processed unexpected things: they put a cup in your hands and waited to see what you did with it.
He drank the coffee. It was strong. He liked it.
"Where are you headed?" the first mate asked.
"East. Following someone."
"Pirate?"
"I don't know yet." He said it honestly. "He has a wanted poster but he doesn't feel like most of the pirates I've met."
"What does he feel like?"
Goku thought about the grinning face on the paper. About the specific quality of that signature — loud and open and completely without the compressed wariness of someone who'd learned the world was dangerous.
"Uncomplicated," he said. "Like someone who hasn't learned to lie to himself yet."
The first mate was quiet for a moment. Then: "Straw Hat Luffy."
Goku looked at her.
"We crossed paths with him two days ago near Orange Town," she said. "He helped a village. Didn't ask for anything. Broke a man called Buggy in half and left before anyone could thank him properly." She paused. "He's heading for the Grand Line. Everyone can see that. The question is whether he gets there."
"What's in the way?"
"Between here and the Grand Line? Smoke — Captain Smoker, Marine Captain at Loguetown. Arlong on the Conomi Islands. And before Arlong —" She hesitated. "There's a woman. Navigator. She's been stealing from pirates for years to buy back her village. She's heading toward Arlong too, but not the way Luffy is."
Goku filed all of it — names, directions, the shape of what was moving in this sea. The world was becoming a map in his head, not geographic but relational. People connected to problems connected to places.
"Thank you," he said. He set down the coffee cup and stood.
"You're going after him."
"I want to see who he is in person." He paused. "The poster only tells you so much."
She looked at him for a moment. "You said you were following someone. Not two people."
"There's a swordsman with him. Green hair."
Something crossed her face — quick, complicated. "Roronoa Zoro?"
"You know him?"
"Everyone in the East Blue knows that name." She said it carefully, the way people said things they'd been trying to decide how to feel about for a while. "He was a bounty hunter. They say he was decent at it — only took bounties on actual criminals. Never hurt bystanders." A pause. "And then he got captured by Morgan and spent a month tied to a post rather than break his word."
"I heard."
"He said it was just practical." The first mate's voice had a quality in it now — not quite admiration, not quite something else. "There was nothing practical about it. He just — " She stopped. Shook her head. "He's the kind of stupid that looks like principle if you squint."
Goku smiled.
"Yeah," he said. "That's the interesting kind."

East Blue — Open Sky — Late Morning
He was back in the air when he felt the third signature.
Not Luffy — that warm, loud brightness was still northeast, maybe fifteen kilometers now, getting closer. Not the compressed, pointed quality that was Zoro.
Something else.
Below him, closing on Luffy's position from the south, moving fast — a ship under full sail, pushed by intent. And on it, a single signature that made him stop midair and actually look.
It was different from everything else he'd felt since he arrived.
Not stronger than him — he could tell that much, the way you could tell the difference between a campfire and a furnace. But the quality of it was precise in a way nothing else here had been. Disciplined. Each layer locked to the next, no wasted heat, no leakage. Like someone who had spent years learning to hold a flame completely still in a strong wind.
A Marine, he thought. But not like the ones from Shells Town. Not like the captain who'd come after the Black Serpent.
Something senior.
He looked at Luffy's position. He looked at the Marine ship. He ran the geometry.
At current speeds, the Marine would intercept Luffy's boat in about twelve minutes.
Goku tilted in the air, thinking.
He'd told himself, before he left Roca Port: observe first. This wasn't his story. Luffy was a person who made his own decisions, and a world that got fixed by one outsider who was too powerful to lose wasn't really fixed — it was just held down by a different hand. He'd learned that lesson the hard way, twice, on Earth.
Don't interfere unless someone asks. Watch. Learn. Find out who people are before you decide they need saving.
That was the plan.
He watched the Marine ship cut through the water. Precise and fast. The signature on it absolutely focused, pointed at Luffy's position like a compass needle.
He watched Luffy's signature — loud and bright and completely, serenely unaware that anything was coming.
He thought about the grin on the poster.
He thought: twelve minutes.
He thought: I'll just get a closer look.
He told himself this was not the same as interfering.
He was aware, even as he thought it, that this was exactly what he always told himself right before he interfered.
He flew toward Luffy's position anyway.
Below him, the Marine ship's white sails caught the wind and drove harder.
Above it, Goku descended through a sky that was very blue and very open and full of things that were about to happen.
He was, despite everything, smiling.
