Ironwind Harbor looked calm in the morning.
Not peaceful—nothing in North Blue was truly peaceful—but calm in the way a sharpened blade looked calm in its sheath. Ships moved in and out with routine efficiency. Merchants shouted prices. Sailors swore at ropes. Pirates laughed too loudly and kept hands too close to weapons.
And in the middle of that living noise, four hunters slipped away without ceremony.
No speeches.
No dramatic goodbyes.
Just a sail catching cold wind as Aira guided their ship out of port, the town shrinking behind them until it became nothing but smoke threads and watchtowers against a pale sky.
Kenji stood at the bow, arms folded, staring ahead like the sea had personally insulted him.
"Two days north," he said, as if repeating it made the target closer.
Aira kept her hands steady on the helm. "If the wind holds."
"It'll hold," Kenji muttered. "The sea owes me after that storm."
Ryu didn't comment. He stood beside Kenji, posture relaxed, eyes steady on the horizon. His calm wasn't laziness—it was the quiet confidence of someone who had already decided how this would go.
Soren sat near mid-deck, cleaning his rifle slowly even though it was already clean. Habit. Discipline. A way of thinking with his hands.
After a while, Kenji spoke again—quieter this time.
"You really fighting him alone?"
Ryu's eyes didn't leave the horizon. "Yes."
Kenji smirked. "And if he cheats?"
"He will," Ryu replied calmly.
Aira glanced back. "Kenji."
Kenji raised a hand. "I'm not arguing. I'm… checking."
Ryu finally looked at him, faint amusement in his eyes. "You'll get your own fight."
Kenji's grin widened. "Good."
Soren's voice came from behind them, level and precise.
"Captain Drake Vargo is not reckless. He sets fields. He traps. He controls distance."
Ryu nodded once. "Chains."
"Yes," Soren said. "If the reports are accurate."
"They are," Aira replied. "The sailor's hands were shaking when he described it."
Kenji leaned forward slightly, wind tugging at his white hair. "Chains are annoying."
Ryu's mouth twitched. "That's the point."
They sailed in a steady rhythm through the day. The sea remained cold and grey-blue, the wind sharp enough to sting, but stable. No storms. No sea kings. Just open water and the feeling of something waiting ahead.
As the sun began to dip, the air changed.
Not temperature.
Tension.
Aira felt it first—her fingers tightening slightly on the wheel before she even understood why.
"…We're getting close," she murmured.
Kenji glanced at her. "How do you know?"
Aira hesitated, then frowned like she didn't like admitting it.
"I can… feel it," she said quietly.
Ryu glanced back. "Observation?"
Aira's lips pressed together. "It's not clear."
"It doesn't have to be," Ryu replied. "Just listen to it."
Soren looked up briefly. "Sea lanes narrowing ahead."
Kenji squinted at the horizon.
At first, he saw nothing.
Then the shape of the world shifted.
Cliffs.
Black rock formations rising from the sea like broken teeth.
The waves around them rolled differently here, caught and redirected by stone walls that cut into the water at sharp angles. The wind funneled through narrow gaps with a whistling moan, as if the passage itself breathed.
Split Jaw Passage.
It earned its name.
Two massive cliff faces stood opposite each other ahead, forming a narrow corridor of water between them—like a mouth half-open, waiting to bite down.
Aira slowed their approach. "We don't sail straight in."
Kenji nodded once. "Ambush territory."
Ryu's gaze sharpened. "Good."
Soren rose slowly and moved toward the mast rigging. "I'll take height."
Kenji looked at him. "You climbing?"
Soren nodded. "Wind is clean here. Sightlines are good."
He moved with controlled efficiency, climbing the rigging like it was routine. Within moments, he was perched near the upper mast support, rifle ready, eyes scanning the cliff edges and the narrowing sea lane ahead.
Ryu turned slightly. "Aira. Keep us just outside the corridor."
Aira nodded. "I can do that."
Kenji drew his blade halfway, then slid it back in—more a habit than a threat. "So what's the plan? We wave hello and ask Vargo to come out?"
Ryu didn't smile, but his eyes carried a quiet edge.
"We enter," he said. "We force him to show his hand."
Aira stared at him. "You're saying we walk into the trap."
Ryu nodded. "Yes."
Kenji grinned. "Finally. Something honest."
Aira exhaled through her nose. "You two are insane."
Soren's voice drifted down from above. "Movement. Ahead. Left cliff."
All three looked.
At first it was only a shadow.
Then a ship slid into view from behind the cliff's edge—large, clean, moving with the calm confidence of something that owned the corridor.
Its sail bore a stylized iron fang insignia—different from the Silver Wolves, sharper, more deliberate. Its hull was reinforced, its cannons positioned like teeth.
And at its bow—
A man stood with arms folded, coat snapping in the wind, as if he'd been waiting for them specifically.
Captain Drake Vargo.
Even from this distance, he didn't look like a man who chased scraps. He looked like a predator who made oceans smaller.
Kenji's grin widened. "That's him."
Aira's voice turned quiet. "Fifty-eight million."
Ryu's gaze never wavered. "Numbers don't matter."
They moved closer, still not committing fully into the corridor. Vargo's ship drifted forward too, matching them—slow, measured, refusing to waste speed.
Then Vargo raised one hand casually.
And the sea changed.
Metal clinked.
A sound that didn't belong to waves.
From beneath Vargo's deck, chains rose.
Not attached to anything visible at first—then the water bulged and a thick iron chain burst upward, glistening wet, and coiled like a serpent over the bow.
Another followed.
Then another.
Each chain moved with unnatural precision, as if guided by thought rather than physics.
Aira's breath caught. "Devil fruit…"
Kenji leaned on the rail, amused. "Chain-Chain Fruit. That's definitely annoying."
Ryu's eyes sharpened slightly. "Good. We know what he is."
Vargo's voice carried across the narrowing water, calm and clear.
"Well now," he said, "the sea really does bring interesting things when you stop it from flowing."
He tilted his head slightly, gaze moving across their deck.
Three bounties.
One extra presence.
He smiled faintly.
"Kenji," he called out, almost friendly. "Fifty-two point two."
Kenji waved. "That's me!"
Vargo's eyes slid to Ryu. "Ryu. Forty-eight point nine."
Ryu didn't respond.
Then Vargo's gaze settled on Aira. "And Aira… nine point two."
Aira's expression didn't change, but her hands tightened on the helm.
Vargo's eyes drifted to Soren's mast perch.
"And the fourth," he mused. "Not on paper yet."
Soren didn't move.
Vargo's smile deepened, as if that amused him.
Then he spoke again, voice calm but heavy.
"You've been interfering with shipments," he said. "North Blue doesn't like that."
Kenji leaned forward, cheerful. "North Blue can complain to the sea."
Vargo laughed softly, then lifted his hand again.
The chains rose higher—more visible now, more numerous. Some draped over his ship's railings. Others sank beneath the water and moved like unseen currents.
Then figures appeared on Vargo's deck.
Three.
They stood spaced apart like officers who knew their roles.
The first was a tall, broad-shouldered man with a thick scar running across his collarbone and a massive iron club resting on one shoulder. His expression was bored, like he'd already decided how this would end.
Vargo spoke as if introducing business partners.
"**Rask 'Anchor' Mullen,**" he said, nodding toward the clubman. "My enforcer."
The second was leaner, dressed too neatly for a pirate, with a long curved blade at his hip and a smug calm in his eyes—like a man who enjoyed winning through technique.
"**Silas Wren,**" Vargo continued. "My cutter."
The third stepped forward last.
And even from across the water, the air shifted.
A woman—tall, athletic, hair tied back tight—rolled her shoulders once, and a faint shimmer moved across her skin like heat over stone. She smiled the way a knife smiled.
"**Mira 'Wiremouth' Kael,**" Vargo said. "My vice captain."
Kenji's grin faded into something sharper.
Aira's eyes narrowed.
Soren's posture above shifted slightly.
Ryu's gaze held steady.
Then Vargo's vice captain lifted her hand and—
Something snapped in the air.
Not sound.
Pressure.
A thin, almost invisible line flickered between her fingers and the deck railing, vibrating like a living thread.
Kenji blinked once.
"…That's a devil fruit too," he said.
Vargo smiled as if pleased by their understanding.
"Mira's a special one," he called. "Don't break too easily."
Kenji's grip tightened on his sword hilt, the excitement returning brighter than before.
Aira muttered, "Of course."
Ryu stepped forward to the bow, calm as ever.
"We're not here to talk," he said.
Vargo's smile widened.
"Good," he replied. "Talking wastes time."
Then his tone shifted—still calm, but colder.
"You wanted a hunt," he said. "So here it is."
The chains dipped beneath the water.
The sea around their ship rippled—subtle, deliberate.
Aira felt it and her Observation flared instinctively.
"Ryu—!" she warned.
Ryu's eyes narrowed. "I know."
The water in front of them bulged—
And a chain burst upward like a harpoon, whipping toward their bow with crushing force.
Kenji moved instantly—
But Ryu raised a hand slightly.
"I've got him," he said.
His voice carried no ego.
Only decision.
Kenji hesitated for half a beat, then stepped back, teeth bared in a grin that was half-respect and half-frustration.
"Fine," he muttered. "But if you die, I'm laughing."
Aira snapped, "KENJI!"
Kenji shrugged. "He knows."
Soren's voice came down calm from above. "Commanders moving. They're splitting."
Vargo's deck shifted into motion.
Rask 'Anchor' Mullen stepped toward the starboard side, eyes on Aira's ship like it was a crate to break.
Silas Wren moved left, blade sliding free with a quiet whisper, eyes tracking Soren's mast position.
And Mira 'Wiremouth' Kael—vice captain—smiled wider as she stepped forward, thin shimmering line dancing between her fingers like a living weapon.
Kenji's grin returned—sharp and eager.
"…Oh," he said softly. "That one's mine."
Ryu's knives flashed as he intercepted the first whipping chain, Armament hardening along his forearms as he cut—not the chain itself, but the momentum, redirecting it just enough to keep it from crushing the bow.
The impact still shook the deck.
Vargo watched from across the corridor, eyes bright with interest.
He hadn't even moved from his bow.
Yet the sea around them was already full of his reach.
Ryu lifted his gaze.
Their eyes met across the narrow water.
Vargo smiled.
Ryu didn't.
And then, without any further words—
Split Jaw Passage became a battlefield.
Four hunters.
Four targets.
Ryu moving forward alone toward the captain.
The others bracing to meet commanders—until the vice captain's devil fruit made Kenji's patience snap into something gleeful and dangerous.
The hunt had begun.
