Screen 1
News spread quickly across Sabaody Archipelago—Camie had been taken to the Human Auctioning House at Grove 1 to be sold as a rare "item."
The moment Sonic heard that, the air around him shifted.
His semi-Dark aura intensified, dark sparks flickering more aggressively.
"…Sold?"
He went completely still for a second.
Then his eyes narrowed, the cold edge in his voice returning.
"They're treating people like objects."
The anger was controlled—but barely.
Sonic turned toward the direction of Grove 1.
"We're ending this now."
Screen 2
At the Human Auctioning House in Sabaody Archipelago, the crew spotted the biggest problem right away—Celestial Dragons were inside.
That meant any direct attack could trigger an Admiral instantly.
Sonic, in his semi-Dark state, stood still for a moment, thinking.
The dark aura around him flickered, but his mind was clear.
"…If we rush in, everything explodes," he said quietly.
He looked toward the building, then at Monkey D. Luffy.
"But if we don't move, Camie gets sold."
He clenched his fist slightly.
"So we go in fast, controlled… no chaos until we reach her."
Then he added, colder,
"If they force it… we finish it."
Sonic was balancing two things at once now:
protecting the crew from a disaster
not letting injustice continue
That tension is exactly what keeps him in semi-Dark instead of full Dark.
Screen 3
Inside the Human Auctioning House, the auction reached a breaking point.
Despite the crew's efforts to get closer, Saint Charlos casually raised the bid and declared 500 million berries for Camie.
The entire room went silent.
For a moment, no one moved.
Sonic's body went completely still.
The semi-Dark aura around him surged, dark electricity intensifying as he moved closer to a full transformation.
"…500 million… for a person."
His voice dropped, colder than before.
The air around him felt heavier.
"They're not even hiding it."
He looked directly at Charlos, eyes darkening further.
For the first time, it felt like Sonic was on the edge of losing control again.
One more push… and he would fully become Dark Sonic.Screen 4
The tension inside the Human Auctioning House snapped.
Just as everything was about to spiral out of control, Silvers Rayleigh appeared.
With a calm presence, he released a powerful burst of Haki, instantly subduing the guards around the room.
Before anyone could react, he moved to Camie and removed the explosive collar with precise timing.
At that same moment, Sonic's restraint finally broke.
The semi-Dark aura exploded into full Dark Sonic.
Black electricity surged violently around him, his eyes fully darkened.
Even with Rayleigh handling the guards, Sonic's focus was locked on one target.
Saint Charlos.
"…You're done."
His voice was cold and final.
For the first time in Sabaody, Dark Sonic stood completely unleashed in the middle of the auction house.
Screen 5
The moment Monkey D. Luffy struck a Celestial Dragons, the entire situation exploded.
Panic spread across the Sabaody Archipelago as alarms were raised and Marines began mobilizing.
At the same time, Dark Sonic, already pushed past his limit, moved with pure anger.
In a flash of speed, he closed the distance to Saint Charlos and struck him hard, sending him crashing across the floor and leaving him severely injured.
The room fell silent for a second.
That single moment confirmed it.
The Straw Hats had now completely crossed the line with the World Government.
Within minutes, the response came.
Borsalino, a Marine Admiral, was dispatched to the island along with overwhelming naval forces.
Dark Sonic stood still for a moment, aura crackling intensely.
"…Good," he said coldly.
But even as he said it, the weight of what was coming next was clear.
This was no longer a rescue.
This was now a war-level situation.
Screen 6
The battlefield at Sabaody Archipelago turned into chaos as the first Pacifista units—modeled after Bartholomew Kuma—arrived.
Their massive bodies and glowing eyes locked onto the Straw Hats.
Dark Sonic stepped forward alone.
Black electricity surged around him as he faced multiple Pacifistas at once.
"They copied him…"
Without waiting, he moved.
In a burst of speed, Dark Sonic dashed between them, striking with rapid kicks and spinning attacks that echoed across the plaza.
One Pacifista fired a powerful laser beam.
Dark Sonic twisted mid-motion, narrowly avoiding it as the beam tore through buildings behind him.
He countered immediately, launching a high-speed Spin Dash straight into its chest, forcing it back several steps.
Another Pacifista fired from the side.
This time the explosion hit near him, throwing dust and debris into the air.
Dark Sonic slid out of the smoke, still moving, but the pressure was clearly increasing.
Unlike Kuma, these machines didn't hesitate, didn't feel pain, and kept firing relentlessly.
Dark Sonic rushed again, delivering a series of fast strikes across multiple targets, forcing them to stagger but not fully fall.
He stopped for a brief second, breathing heavier.
"…They're not going down easily."
Even in full Dark form, fighting multiple Pacifistas at once was pushing him hard.
But he didn't step back.
Instead, he leaned forward again, aura flaring stronger.
"Then I'll break them one by one."
