Osamu woke up already knowing something was wrong.
Not because of some deep realization or calm analysis — but because his wrists burned.
Metal bit into his skin. Cold. Tight. Real.
His eyes flew open and immediately regretted it.
The world lurched. Wood above him. Wood beneath him. The air stank of salt, sweat, alcohol, and something rotten. His stomach flipped as the floor tilted under him.
A ship.
"No—no, no, no—"
He sucked in air too fast and started coughing, throat raw like he'd swallowed seawater. His head pounded. His heart slammed so hard it hurt.
Chains.
He looked down.
Actually chains.
Bolted into the wall.
Panic hit him full-force, no warning, like someone had kicked his chest in.
"What the fuck—WHERE—"
Laughter answered him.
Rough, ugly laughter.
Boots scraped across wood. Shadows moved. Someone leaned into the lantern light and grinned at him with broken teeth.
"Oh, look. He's awake."
Pirates.
Not actors. Not cosplay. Pirates.
Osamu's brain screamed one clear thought over everything else:
I'm about to die.
A massive woman stepped forward, iron club resting on her shoulder like it weighed nothing. Pink hair. Smug face.
His blood went cold.
"…Alvida."
The name slipped out before he could stop it.
Her eyebrow twitched. "Oh?"
That was it. No more denial. No more hoping.
This was One Piece.
And he was a chained extra about to get beaten to death.
Something snapped into place in his head.
> [SYSTEM ONLINE]
The words slammed into his vision so hard he flinched.
> [Host consciousness confirmed.]
[Survival probability: LOW.]
"Yeah, no shit," he rasped.
Pirates closed in. One cracked his knuckles. Another pulled a knife.
Osamu didn't think.
He reacted.
> [Beginner Reward Pack available.]
"OPEN IT," he snapped mentally, panic flooding every thought. "NOW."
> [Beginner Reward Pack — OPENING.]
Heat surged through his body.
Not gentle. Not gradual.
His muscles tightened like wires pulled too hard. His balance shifted. His breathing snapped into rhythm without him meaning to. Information slammed into his head — not memories, not voices, but instincts.
How to stand.
How to move.
Where not to be.
> [Gamer Body applied.]
[Gamer Mind applied.]
The screaming panic didn't vanish — but it got boxed in, shoved into a corner where it couldn't hijack his hands.
> [Inventory unlocked.]
[Weapon Set acquired.]
Weight appeared at his side.
A katana.
Real.
Heavy.
A pirate lunged.
Osamu didn't think I should dodge.
His body just moved.
The blade came up on instinct, edge catching lantern light as he twisted away. The pirate's knife missed his throat by inches.
Osamu felt something else surge — darker, sharper.
> [Sukuna Template — 10% synchronization.]
For a split second, the world slowed.
The pirate's face was wide open. His grip sloppy. His balance trash.
Osamu spoke without planning to.
"You're panicking," he said flatly. "That's why you're dead."
The pirate froze.
Not physically — mentally.
> [No Talk Jutsu: Parallel — Triggered.]
The man hesitated.
Osamu didn't.
The katana moved.
Blood sprayed warm across his hands.
The body hit the floor.
Silence crashed down around him.
Osamu stared at the blade, chest heaving.
"…I killed him."
The thought landed hard.
Then another pirate charged, screaming.
Osamu's jaw clenched.
Later.
He moved again.
And again.
Not clean. Not heroic. Just fast, brutal, desperate.
By the time the ceiling exploded and a rubber idiot crashed in yelling about meat, Osamu was already standing, blade dripping, eyes sharp, breath steady in a way that scared him.
Luffy landed, looked around, and grinned.
"Whoa! You beat some already!"
Osamu wiped blood off the blade and exhaled.
"…Yeah."
Inside his head, one thought echoed clearly over the rest:
Open rewards first.
Ask questions later.
Survive now.
