The Lantern Festival began at sunset and lasted for three full days.
By nightfall, Aetheron looked like a dream floating atop the sea.
It looked like a constellation drifting across the sea.
Golden lanterns swayed between rooftops on silk ropes while hundreds more floated skyward like wandering stars escaping the ocean below. Music rolled through the harbor in warm waves. Violins danced alongside deep drums while drunken fishermen butchered old sea songs with enough confidence to make up for the lack of talent.
The scent of grilled fish, melted sugar, and sweet seafruit drifted through the wind.
For three days every year during summer, the island forgot the outside world existed.
Kael stood near the docks, staring upward as another cluster of lanterns rose into the heavens.
"…Beautiful," he admitted quietly.
Nami grinned beside him.
"Obviously."
"You say that like you made the sky yourself."
"I practically did."
"No," Nojiko cut in dryly, "you just bullied three people into hanging lanterns for you."
"That's called leadership."
"That's called tyranny."
Kael laughed.
Nami immediately elbowed him in the ribs.
Not hard.
At least not by her standards.
For Nami, it might as well have been a cannon shot.
"Hey!" Kael complained.
"You deserved it."
"You literally threw a barrel at me this morning!"
"You caught it!"
"That's not the point!"
Nojiko sighed with theatrical exhaustion.
"You two can be genuinely unbearable."
Ahead of them, villagers danced beneath glowing banners while musicians played near the shoreline. Children sprinted through the streets carrying paper masks shaped like sea kings and dragons. Elder navigators argued loudly over weather patterns beside overflowing sake barrels.
And for the first time since reincarnating…
Kael didn't think about the future.
No Marines.
No Celestial Dragons.
No looming destiny.
Just warmth.
Bekka suddenly appeared beside him, carrying enough grilled meat skewers to feed a small army.
"My son!" she announced proudly. "Eat."
Kael stared at the mountain of food.
"…Mother, this is enough to kill a normal person."
"You are not normal."
"That's becoming increasingly concerning."
Bekka's laughter boomed across the harbor hard enough to startle nearby seagulls into flight.
Even surrounded by celebration, she stood out like a force of nature.
Silver hair spilled across her shoulders beneath the lantern light while the enormous claymore strapped across her back drew wary glances from strangers.
The blade looked ancient.
Not forged.
Inherited.
Dark steel layered like polished obsidian stretched down toward a wolf-headed guard that looked ready to sink its fangs into the world itself.
Kael caught himself staring at it again.
Bekka noticed immediately.
Her expression softened.
"One day," she said quietly, "you'll carry a blade greater than mine."
Kael blinked.
Something tightened painfully inside his chest.
Something about the way she said it made his chest tighten unexpectedly.
Before he could answer, Bjorn's booming laughter rolled across the harbor.
The massive Buccaneer sat surrounded by villagers while several men unsuccessfully attempted to outdrink him.
"Again!" Bjorn roared.
"You've already beaten us seven times!" one fisherman cried.
"Then become stronger!"
"That's not how alcohol works!"
Kael snorted.
Nami tugged his sleeve suddenly.
"Come on."
"Where?"
"You're going to ruin the festival if you keep standing around looking mysterious."
"I do not look mysterious."
Nami and Nojiko stared at him.
"…You literally glare at the ocean like a retired Marine," Nojiko deadpanned.
Kael opened his mouth.
Then closed.
"…Fair enough."
Hours passed in laughter.
Kael helped villagers hang lanterns after accidentally lifting an entire support beam by himself. Nami became irrationally competitive during a ring toss game and accused the booth owner of "anti-genius bias." Nojiko won a navigation puzzle contest in under two minutes and acted unbearably smug afterward.
Somewhere during all of it...
Kael stopped feeling like a reincarnated outsider.
A little old woman grabbed his cheek and complained that he was "getting too big too fast." Fishermen laughed about how terrifying he would become as an adult. Children followed Bekka around the festival like ducklings following a war goddess.
And everywhere Bjorn walked, people smiled.
Not because they feared him.
Because they trusted him.
That hit Kael harder than he expected.
Strength in the world of One Piece usually isolates or corrupts people.
But here?
Strength protected.
Three hours later, the four of them sat atop the cliffs overlooking the harbor.
Hundreds of floating lanterns drifted above the sea below like scattered stars.
Tonight, even the ocean looked merciful.
Nami leaned against Kael's shoulder absentmindedly while sketching rough island maps into a notebook.
"I'm going to map the entire world someday," she declared.
"You say that every day," Nojiko muttered.
"Because it's true every day."
Kael smiled faintly.
"I'll believe you'll do it."
Nami looked at him.
" You really believe that I can?"
Kael stared toward the horizon where lantern light met endless darkness.
"I think people like you are the reason the world keeps moving forward."
For once, Nami had no sarcastic comeback.
Her cheeks turned faintly pink.
"…You're weird sometimes."
"Only sometimes?"
"Shut up."
Below them, another wave of lanterns rose into the night sky.
Kael watched them drift higher and higher until they vanished among the stars.
He realized something.
He didn't want adventure right now.
He just wanted tomorrow.
The island woke to silence.
No harbor bells.
No gulls.
No laughter remained.
Kael was jolted awake.
Something was wrong.
BOOM!
The harbor exploded.
The entire house shook violently as another cannon blast thundered across the island.
Screams erupted outside.
Firelight flashed across the walls.
"NAMI!"
Kael moved instantly.
He burst into the hallway just as Bjorn ripped a massive war hammer from the wall.
The weapon's axe-like edge gleamed beneath the firelight.
"Father, what's happening?"
"Get the girls and run!" Bjorn barked.
The warmth from the past three nights vanished from his voice.
It sounded like a war drum.
Outside, chaos consumed Aetheron.
Marine warships surrounded the harbor.
Not one.
Not two.
But an entire fleet.
Cannons roared across the shoreline while smoke swallowed the sky overhead. Burning festival lanterns drifted through the streets like dying stars. Marines flooded the island in organized ranks while civilians scattered in panic.
Paper masks lay trampled beneath boots.
Festival ribbons burned across rooftops.
Blood mixed with seawater in the streets.
Kael's stomach twisted.
Near the harbor, mounted figures dressed in immaculate white armor watched the slaughter unfold calmly.
Celestial Dragons.
"No…" Kael whispered.
This wasn't a raid.
It was a hunt.
Far offshore, another ship cut violently through the waves.
Monkey D. Dragon stood at the bow while the wind screamed around him like a living thing.
"Aetheron…" Ivankov muttered grimly.
Kuma lowered his head silently.
Dragon's expression darkened.
"We won't make it in time," he said.
Ahead of them, Marine ships formed a blockade around the burning island.
Elsewhere across the sea
Elsewhere across the sea, Garp crushed a den-den mushi receiver inside his hand.
"Sengoku," he growled, "tell me you're joking."
Static crackled briefly before Sengoku's exhausted voice answered.
"The Holy Knights are involved. Dragon is already moving toward the island."
Garp's expression hardened instantly.
"…Damn Celestial Dragons."
Bogard adjusted his fedora nearby.
"Orders, Vice Admiral?"
Garp grabbed his coat.
"We move now."
He paused briefly.
"…Hope this doesn't become another damn Ohara."
Aetheron burned.
Kael ran through smoke-filled streets while holding Nami's hand tightly. Nojiko stayed close behind him.
Screams echoed everywhere.
The smell hit hardest.
Fire.
Blood.
Saltwater.
Death.
Kael's breathing sharpened.
"System," he whispered desperately.
Nothing.
"Come on…"
Still nothing.
Ahead of them, civilians collapsed beneath rifle fire while Marines dragged screaming villagers toward chained wagons.
Then Kael saw her.
Bekka.
The massive Oni stood in the middle of the street like a demon from an ancient myth. Her claymore carved through the battlefield with terrifying force.
Not elegant.
Not graceful.
Each swing felt catastrophic.
One slash split a Marine cannon clean in half.
Another sent armored soldiers flying like broken dolls.
The wolf-headed blade screamed through smoke and fire alike.
Then a man stepped forward.
White armor.
Cold eyes.
Holy Knight Callahan.
His gaze slid across Bekka slowly.
Hungrily.
"Well now…" he murmured.
Kael felt sick instantly.
"You will make a wonderful addition to my collection."
Bekka's expression twisted with disgust.
"Try it."
Callahan smiled.
Then his eyes shifted toward Kael.
The amusement deepened.
"Oh?"
His gaze lingered on Kael's horns.
His size.
His monstrous frame, despite his age.
"…An Oni-Buccaneer hybrid."
Kael's blood froze.
"That's rare. I haven't seen such a rare hybrid in years."
Callahan licked his lips slightly.
"You'll make a fascinating plaything."
Something inside Kael snapped.
Bjorn appeared instantly.
BOOM.
A haki-coated claw slash tore through the street toward Callahan with enough force to split buildings apart.
Callahan dodged backward smoothly, blocking with the sheath of his katana.
Bjorn's body expanded violently as black fur erupted across his arms and shoulders.
The Kuma Kuma no Mi: Model Black Bear.
The ground cracked beneath his feet.
"Son," Bjorn growled, "take the girls and run."
Kael hesitated.
"Now!"
For the first time since arriving in this world…
Kael felt afraid.
Not for himself.
For them.
They turned to run.
Then a shrill voice echoed nearby.
"Aye!"
A bloated Celestial Dragon pointed toward Kael excitedly.
"That child! Capture him!"
His eyes gleamed greedily.
"He'll make an excellent servant!"
Marines surged forward instantly.
Kael shoved Nami and Nojiko behind him.
"Stay back."
The first guard swung.
CRACK.
Kael broke the man's arm instinctively.
Another Marine charged.
Kael slammed him into the ground hard enough to crater stone.
But there were too many.
Blades cut across his arms.
Gunfire tore through nearby walls.
Pain exploded through him.
Scars burned across his body.
Still, Kael refused to fall.
Not while Nami was crying behind him.
Not while Nojiko trembled.
The Marines then surrounded them.
"Stand down, kid."
Kael laughed weakly despite the blood running down his face.
"…Is this how Marines act?" he asked.
His voice shook with fury.
"Pointing guns at children?"
Several Marines hesitated.
One woman stepped forward suddenly.
Young.
Orange hair.
Terrified eyes filled with anger.
Bellemere.
"What are you doing?!" she shouted.
Her rifle turned toward the Marines instead.
"They're children!"
Her commanding officer snarled immediately.
"Stand down, Marine! Those brats attacked a Celestial Dragon!"
Belle-mere's hands trembled.
"No."
Silence.
Absolute silence fell as footsteps could be heard.
"Damn."
A deep voice echoed across the battlefield.
"You dam, Celestial Dragons are still disgusting as ever."
The pressure shifted instantly.
Garp walked through the smoke casually while cracking his knuckles with Bogard in tow.
Bogard rested his hand on his blade, just waiting for a single word from Garp.
Marines straightened automatically.
Fear spread across the battlefield.
"V-Vice Admiral Garp!"
Garp ignored them completely.
His eyes landed on Kael.
Then Nami.
Then Nojiko.
Then the burning island.
For a brief moment…
His smile disappeared entirely.
Belle-mere swallowed nervously.
"Vice Admiral, what about the boy?"
Garp snorted.
Then grinned.
"I'd like to see who's stupid enough to touch my new grandson."
Kael blinked slowly.
"…Old man," he rasped, "who are you calling grandson?"
Garp's fist crashed into his head instantly.
THUNK.
"Brat talks too much."
Darkness swallowed Kael whole.
When Kael woke again…
Everything hurt.
The scent of medicine filled the room.
Wood creaked softly beneath him.
Ocean waves rocked gently outside.
A ship.
Kael's eyes opened slowly.
"…Nami?"
Silence answered him.
Panic surged instantly.
Kael forced himself upright and froze.
Garp sat quietly beside the bed.
For once…
The old Marine wasn't smiling. His face was grim.
Resting across his lap was Bekka's claymore.
The massive wolf-headed blade looked darker now, somehow.
Heavier.
Garp noticed Kael staring.
Slowly…
Carefully…
He lifted the sword and placed it into Kael's trembling hands.
The moment Kael touched it, something shattered inside him.
His breathing broke instantly.
Oni weapons were sacred.
Not tools.
Not possessions.
They were inheritances.
In Oni tradition, a parent marked their child's coming of age by passing down their own weapon or crafting a sister‑weapon in its image, binding lineage and steel together.
"No…" Kael whispered.
His hands shook violently against the sword's handle.
"No…"
Memories crashed into him all at once.
Bekka laughs during training.
His father calls him stronger than him at his age.
Lanterns floating across the sea.
Warm meals.
Nami laughing beside him.
A home.
He had finally found a home again.
And the world took it.
Kael bent forward as silent tears hit the blade.
Not loud.
Not dramatic.
Just broken.
Garp watched quietly.
After a long time, he finally spoke.
"Your mother was terrifying."
Kael laughed weakly through tears.
"…Yeah."
"She carved through three warships before she went down."
Kael's grip tightened.
"And your old man?"
Garp leaned back slightly.
"He fought like a damn monster."
Pride.
Pain.
Respect.
All mixed.
Kael closed his eyes.
"…Did anyone survive?"
Silence answered first.
Then:
"Some."
Garp's voice softened slightly.
"The girls are safe."
Kael exhaled shakily.
Thank God.
Outside the room, he heard familiar voices arguing.
Nami.
Nojiko.
And Belle-mere.
The Marine woman paused outside briefly before speaking quietly.
"I'm done."
Another Marine sounded shocked.
"You're resigning?"
"I joined to protect people," Belle-mere said firmly.
"Not hunt children."
Footsteps faded afterward.
Garp chuckled.
"Got yourself a stubborn one there."
Kael stared down at the massive claymore resting across his lap.
The wolf-shaped guard reflected dim lantern light from outside the cabin window.
For the first time…
The sword didn't feel too heavy.
It felt like waiting.
Garp stood slowly.
Then placed a massive hand on Kael's head.
"Listen carefully, brat."
Kael looked up.
"You lost your family today."
Garp's expression remained calm.
"But from now on…"
A grin slowly spread across his scarred face.
"You're one of mine."
Outside the ship, the sea continued forward endlessly.
Unforgiving.
Alive.
And somewhere deep within Kael's soul…
Something answered it back again.
This time not with grief.
But resolve. Kael ran through smoke-filled streets while gripping Nami's hand tightly. Nojiko stayed close behind him.
Screams echoed everywhere.
The smell hit hardest.
Smoke.
Saltwater.
Blood.
Death.
Kael's breathing sharpened.
"System," he whispered desperately.
Nothing.
"Come on…"
Still nothing.
Ahead of them, civilians collapsed beneath rifle fire while Marines dragged screaming villagers toward chained wagons.
Then Kael saw her.
Bekka.
The massive Oni stood in the center of the ruined street like a demon pulled from ancient myth.
Her claymore tore through the battlefield with catastrophic force.
Not elegant.
Not graceful.
Every swing looked capable of splitting the island itself.
One slash cleaved a Marine cannon clean in half.
Another sent armored soldiers flying like shattered dolls.
The wolf-headed blade screamed through smoke and fire alike.
Then someone stepped forward.
The battlefield changed instantly.
Marines straightened.
The air itself seemed heavier.
Even the flames crackling around the ruined buildings felt quieter.
White armor gleamed beneath drifting ash.
Holy Knight Callahan.
An eyepatch rested over one eye while the other studied the battlefield with cold amusement. His immaculate coat fluttered behind him, untouched by soot or blood, gold-lined like royal vestments.
A black katana rested casually against one shoulder.
He looked less like a soldier and more like an executioner who had mistaken war for entertainment.
His gaze slid across Bekka slowly.
Hungrily.
"Well now…" he murmured.
Kael felt sick instantly.
"You will make a magnificent addition to my collection."
Bekka's expression twisted with disgust.
"Try it."
Callahan smiled.
Then his attention shifted toward Kael.
The amusement deepened.
"Oh?"
His eye lingered on Kael's horns.
His size.
His monstrous frame, despite his age.
"…An Oni-Buccaneer hybrid."
Kael's blood froze.
"That's rare," Callahan mused softly. "I haven't seen one in years."
A smile stretched slowly across his face.
"You'll make a fascinating pet."
Something inside Kael snapped.
Bjorn appeared instantly.
BOOM.
A haki-coated claw slash erupted through the street toward Callahan with enough force to split buildings apart.
Callahan slid backward smoothly, blocking with the sheath of his katana.
The impact shattered the road beneath his feet.
Bjorn's body expanded violently as black fur erupted across his arms and shoulders.
The Kuma Kuma no Mi: Model Black Bear.
The ground cracked beneath him.
"Son," Bjorn growled, "take the girls and run."
Kael hesitated.
"NOW!"
For the first time since arriving in this world...
Kael felt truly afraid.
Not for himself.
For them.
He turned.
Then a shrill voice rang across the battlefield.
"AYE!"
A bloated Celestial Dragon pointed toward Kael excitedly.
"That child! Capture him!"
Greed gleamed inside his eyes.
"He'll make an excellent servant!"
Marines surged forward instantly.
Kael shoved Nami and Nojiko behind him.
"Stay back."
The first Marine swung.
CRACK.
Kael broke the man's arm instinctively.
Another charge.
Kael slammed him into the ground hard enough to crater stone.
But there were too many.
Blades carved across his arms.
Gunfire shattered nearby walls.
Pain exploded through his body.
Still, Kael refused to fall.
Not while Nami was crying behind him.
Not while Nojiko trembled.
The Marines surrounded them.
"Stand down, kid."
Kael laughed weakly despite the blood running down his face.
"…Is this justice?" he asked.
His voice shook with fury.
"Pointing guns at children?"
Several Marines hesitated.
Then one woman stepped forward.
Young.
Orange hair.
Furious eyes, trembling with disbelief.
Belle-mere.
"What are you doing?!" she shouted.
Her rifle turned toward the Marines instead.
"They're children!"
Her commanding officer snarled immediately.
"Stand down, Marine! Those brats attacked a Celestial Dragon!"
Belle-mere's hands shook.
"No."
Silence spread across the battlefield.
Then footsteps echoed through the smoke.
Heavy.
Unhurried.
"Damn…"
A deep voice rumbled across the ruined harbor.
"You Celestial Dragons are still disgusting as ever."
The pressure shifted instantly.
Marines straightened automatically.
Fear spread through the battlefield.
Garp walked through the smoke while casually cracking his knuckles.
Bogard followed beside him with one hand resting on his blade.
"V-Vice Admiral Garp!"
Garp ignored them.
His eyes swept across Kael.
Then Nami.
Then Nojiko.
Then the burning island behind them.
For a brief moment...
His grin disappeared entirely.
Belle-mere swallowed nervously.
"Vice Admiral… what about the boy?"
Garp snorted.
Then grinned.
"I'd like to see who's stupid enough to touch my new grandson."
Kael blinked slowly.
"…Old man," he rasped, "who are you calling grandson?"
Garp's fist slammed into his head instantly.
THUNK.
"Brat talks too much."
Darkness swallowed Kael whole.
When Kael woke again...
Everything hurt.
The scent of medicine filled the room.
Wood creaked softly beneath him.
Ocean waves rocked gently outside.
A ship.
Kael's eyes opened slowly.
"…Nami?"
No answer came.
Ice flooded Kael's chest.
He forced himself upright and froze.
Garp sat quietly beside the bed.
For once, the old Marine wasn't smiling.
Resting across his lap was Bekka's claymore.
The massive wolf-headed blade looked darker now.
Heavier.
Garp noticed Kael staring.
Slowly, he lifted the sword and placed it into Kael's trembling hands.
The moment Kael touched it, something shattered inside him.
His breathing broke instantly.
Oni weapons were sacred.
Not tools.
Not possessions.
They were inheritances.
A parent either passed down their weapon or forged a sister-blade in its image, binding steel and blood together across generations.
"No…" Kael whispered.
His hands trembled violently against the handle.
"No…"
Memories crashed into him all at once.
Bekka laughs during training.
Bjorn told him that he was stronger than he had ever been at that age.
Lanterns drifting across the sea.
Warm meals.
Nami laughing beside him.
A home.
He had finally found a home again.
And the world took it.
Kael bent forward as silent tears struck the blade.
Not loud.
Not dramatic.
Just broken.
Garp watched quietly.
After a long silence, he finally spoke.
"Your mother was terrifying."
Kael laughed weakly through tears.
"…Yeah."
"She carved through three warships before she went down."
Kael's grip tightened.
"And your old man?"
Garp leaned back slightly.
"He fought like a damn monster."
Pride.
Pain.
Respect.
All tangled together.
Kael closed his eyes.
"…Did anyone survive?"
Silence answered first.
Then:
"Some."
Garp's voice softened slightly.
"The girls are safe."
Kael exhaled shakily.
Outside the room, familiar voices argued.
Nami.
Nojiko.
And Belle-mere.
The Marine woman paused outside briefly before speaking.
"I'm done."
Another Marine sounded stunned.
"You're resigning?"
Belle-mere's voice hardened.
"I joined to protect people. Not hunt children."
Footsteps faded afterward.
Garp chuckled.
"Got yourself a stubborn one there."
Kael stared down at the massive claymore resting across his lap.
The wolf-headed guard reflected dim lantern light from the cabin window.
For the first time...
The blade didn't feel too heavy.
It felt patient.
Waiting.
Garp stood slowly.
Then placed a massive hand on Kael's head.
"Listen carefully, brat."
Kael looked up.
"You lost your family today."
Garp's expression remained steady.
"But from now on..."
A grin spread across his scarred face.
"You're one of mine."
Outside the ship, the sea rolled endlessly beneath the moonlight.
Cold.
Restless.
Alive.
And somewhere deep within Kael's soul...
Something answered it back.
Not grief.
Not fear.
Resolve.
