When Kai stepped into the Boss's room, the man looked at him carefully—but did not recognize him.
He frowned and said coldly,
"Who are you? I don't remember ever buying a broken tool like you."
Those words struck Kai like a blade.
A tool.
The hatred inside him grew even stronger. His voice was calm, but filled with killing intent.
"Today will be your last day. I will kill you."
The Mafia Boss burst into laughter.
"HAHAHAHA! So the power of a Devil Fruit gave you this much courage?"
He stood up from his chair. In his hand was a sword. Slowly, confidently, he walked toward Kai.
"I've fought many strong people in my life—
even Devil Fruit users.
And now some slave thinks he can kill me?"
His eyes sharpened.
"I'll show you what true strength is."
He placed his hand on the hilt of his sword and took a stance.
"One-Sword Style—
Air Blade Technique."
He swung his sword.
A sharp blade of compressed air flew toward Kai.
Kai felt his mist warning him of danger. Instinctively, he moved to the side.
The air slash missed him and struck the door behind, cutting it cleanly in half.
Kai's expression changed.
An air blade…
Is he a master swordsman?
Suddenly—danger again.
His mist warned him from the right.
In the next instant, the Boss appeared beside him and swung his sword, aiming straight for Kai's neck.
He was too fast.
Kai had no time to react.
But the blade passed straight through Kai's neck—without harming him.
The Boss froze in shock.
"What—?!"
Kai's neck slowly transformed into mist before returning to normal.
The Boss's eyes widened.
"This… is a Logia-type Devil Fruit?!"
"Just like that damn Vice Admiral of the Marines…"
The Boss knew how rare Logia fruits were—and how valuable.
To think that this slave had obtained one…
He smirked.
"You're really lucky.
A Logia-type fruit… even if it's just mist."
He lowered his sword slightly.
"Let's stop this fight.
I'll give you anything you want—money, women, power.
You'll live a rich life."
"Work for me."
He looked straight at Kai, confident.
Kai listened quietly.
Then… he smiled.
"I don't need to work for trash like you," Kai said calmly.
"As I already told you—
I'm going to kill you."
The Boss's expression darkened instantly.
"…Fine."
"I wanted to be reasonable," he said coldly.
"But if you want to fight, then we'll fight."
"And when I catch you, I'll sell you to another mafia."
"A Logia-type slave is extremely rare."
He took his stance again.
Kai clenched his teeth.
I can't fight him properly in this room.
The office was large—but not large enough.
His stamina wasn't infinite.
He needed space.
Outside…
Kai spread his mist slightly and quickly scanned the room.
There.
An open window.
Without hesitation, Kai turned and ran.
