Chapter 1
BOOM!!!
An explosion erupted beside Ren, hurling him through the air like a rag doll. His body slammed hard against the ground, rolling until he lay beside a massive corpse. Before Darkness swallowed him whole.

When Ren finally opened his eyes, the world around him was frozen — mid-motion. A glowing countdown ticked silently before his eyes.
Scrambling to his feet, he realized he was no longer in his own body. Confused, he looked around; the battlefield was in ruins. Rugged men and soldiers in white uniforms were locked in combat — frozen in time, mid-strike.
Then he saw it. A giant green-skinned figure, almost monstrous, lying dead nearby — a face he recognized immediately.
And in that instant, everything clicked.
Drinking with his friends…
Then blacking out…
Now waking up here — in Marineford, during the War of the Best.
Ren's mouth fell open in disbelief.
"This is definitely unreal…" he muttered.
After a few minutes of stunned silence, he steadied his breath. His life on Earth was already ruined by his ex; this time, he would live without regrets.

The System's Voice
Without warning, the screen before him flickered to life.
"Welcome to the One Piece wor...rl...rld... Sorry — we've been informed that an error occurred on our end. As compensation, please accept the following gifts."
1. For every three dead bodies you touch, you'll randomly gain one of their attributes.
2. You are granted a subspace.
3. You are given the Mythical Zoan Devil Fruit — Bird-Bird Fruit, Model: Red Phoenix (Saku-Saku Bird).
"That's all. Thanks for your time."
Ren blinked, dumbfounded. "Did I just… get scammed by a system?"
Before he could process what happened, time suddenly resumed.

"Whoa…" Ren gasped as the world burst back into motion — explosions, screams, and chaos everywhere.
Testing the strange system, he placed his hand on the enormous body beside him — Little Oars Jr., the fallen giant.
Immediately, a holographic circle appeared before his eyes, covered with spinning symbols. The pointer spun wildly, then stopped.
[Attribute Gained: Innate Superhuman Strength and Giant Physique]
Ren's body pulsed with power. His bones shifted, muscles tightened, and warmth flooded through him. Surprisingly, the transformation wasn't painful — it was exhilarating.
Grinning, he dashed across the battlefield, dodging stray bullets and sword slashes. His eyes landed on a fallen Marine Vice-Admiral nearby.
Without hesitation, he sprinted toward the corpse, weaving between attacks, and touched the body. The circular screen appeared again, spinning rapidly.
Ren ignored it for the moment, focusing instead on staying alive. Though an amateur, his movements were sharp and calculated — far beyond anything he had learned before.
Finding a quiet corner, he glanced down at his hands.
"Where did I get these moves from…?"
As he wondered, unfamiliar memories began flooding into his mind — someone else's life.
A boy lost at sea…
Years spent rising through the Whitebeard Pirates…
Mastering Observation Haki…
And finally — death at Aokiji's hands.
It all made sense now. This was the body's original owner. His instincts — and his haki — still lingered within.
Among the memories, one detail stood out: a report he once gave Whitebeard about a secret World Government experiment site.
Ren stored that information away for later and refocused as another notification appeared before him:
[Skill Acquired: Master Swordsmanship]
Suddenly, the world around him shifted. He could feel the breath of every living thing — even the air itself.
"So this came from the Vice-Admiral…" he murmured.
A Marine soldier lunged at him with a sword.
In a flash, Ren drew a blade from his waist. The movement felt natural — perfectly familiar.
He exhaled slowly, closing his eyes. The chaos faded. It was as if time itself slowed for him alone.
With a single swing, he cleaved both the Marine and his blade cleanly in two.
The sensation thrilled him.
Adrenaline surging, Ren charged into the fray, slashing through Marines with newfound precision. Each movement felt like art , deliberate, powerful, alive.
Cracks began to form along his sword's edge, but he didn't care.
A smirk spread across his face as he locked eyes on his next target.
"Let's keep this going."
