Under the eager gaze of Robin and the others, Kaito stepped aside to give himself some room.
Let's test the Kilo-Kilo Fruit first.
He loosened his shoulders and stretched briefly before leaping over the ship's railing, dropping straight toward the sea below.
The moment he activated the ability, his body instantly became lighter.
As he neared the water's surface, he lightly tapped it with his feet.
For a brief instant, his greatly reduced weight allowed him to skim across the sea using only the faint buoyancy of the water beneath him.
In a flash, he had already dashed dozens of meters away.
Running across the ocean.
Kaito transformed into a streak of lightning racing over the sea.
His speed increased continuously.
Soon, he was moving so fast that his figure disappeared completely, leaving behind only a blur too quick to follow.
"So fast!"
"What kind of speed is that?"
"I can't even track Captain's movements with Observation Haki!"
"What ability is Captain using?"
Robin, Zoro, Law, Lafayette, Smoker, Neferpitou, and everyone else hurried to the railing the moment Kaito jumped from the ship.
Watching him race across the sea at a speed that even Observation Haki couldn't follow left everyone speechless.
It was the power of the Kilo-Kilo Fruit.
The Devil Fruit formerly possessed by Miss Valentine of Baroque Works.
Now, however, Kaito had stored her within the alternate space created by the Munch-Munch Fruit, allowing him to freely utilize her Devil Fruit ability.
His body weighed only a single kilogram.
That dramatic reduction in weight created changes far beyond merely running across water.
Skimming over the sea was only the most obvious effect.
The true advantage lay in his speed.
His physical strength and explosive power remained exactly the same.
With far less body weight to move, his speed naturally increased to an astonishing degree.
Reducing himself to a single kilogram allowed him to unleash movement speed on an entirely different level.
Even if he had possessed this speed while fighting Kuzan...
Even with the Admiral's superior Observation Haki...
It would have been difficult for Kuzan to perceive and evade every attack.
That battle would likely have unfolded very differently.
After spending some time testing the effects of reducing his weight...
Kaito shifted to the opposite extreme.
His figure suddenly reappeared in the sky.
He leaped high into the air.
At the peak of his jump...
He instantly increased his weight to the maximum.
Ten thousand kilograms.
Boom!!
Like a meteor falling from the heavens, Kaito descended toward the sea below.
At the moment of impact...
He threw a punch.
A deafening explosion erupted.
Towering waves surged upward, reaching heights of dozens of meters.
His single punch blasted a gigantic funnel-shaped crater into the ocean over one hundred meters across.
For a brief instant...
The seawater seemed completely frozen.
Only after the tremendous force dispersed did the surrounding water come roaring back.
The ocean collapsed inward, forming a massive whirlpool.
Before the seawater completely rushed back into the crater...
Kaito had already reduced his weight to a single kilogram again.
His body became feather-light.
With barely any effort, he floated back into the air.
Looking down at the enormous whirlpool beneath him, Kaito nodded in satisfaction.
Increasing my weight really does amplify my attack power dramatically.
If reducing his weight granted overwhelming speed...
Then increasing it granted overwhelming destructive force.
Ten thousand kilograms alone meant very little to Kaito.
However...
When that weight combined with his already monstrous physical strength...
The increase wasn't simple addition.
It bordered on multiplication.
After personally testing the Kilo-Kilo Fruit...
Kaito found himself even more satisfied with its capabilities.
There was a saying in the world:
A Devil Fruit's true power depends on its user.
The statement wasn't entirely accurate.
But it wasn't wrong either.
Take the Kilo-Kilo Fruit as an example.
In Miss Valentine's hands...
It relied almost entirely on its own ability.
But in Kaito's hands...
It functioned like an enormous amplifier.
Even someone as powerful as Kaito received tremendous benefits from it.
Now...
Let's test the other one.
Watching the whirlpool gradually settle, Kaito considered his next experiment.
He reached up.
Plucked a single strand of hair from his head.
Then casually flicked it into the air.
The strand drifted with the wind.
Rather than falling directly beneath him, it floated dozens of meters away before touching the ocean's surface.
Boom!!
The location had changed.
The ability attached to it had not.
The instant the hair touched the water...
It exploded like a cannon shell.
A towering pillar of seawater erupted into the sky.
This was the power of the Bomb-Bomb Fruit.
The Devil Fruit formerly possessed by Mr. 5.
Like Miss Valentine, he had also been stored within the alternate space created by Kaito's Munch-Munch Fruit.
The Bomb-Bomb Fruit allowed any part of the user's body to become an explosive.
Even something as insignificant as exhaled breath could be turned into a bomb.
Just attaching the ability to a single strand of hair already creates this much power...
A thoughtful gleam flashed through Kaito's eyes.
Compared to the Kilo-Kilo Fruit...
He actually valued the Bomb-Bomb Fruit even more.
To be more precise...
He believed this Devil Fruit possessed the potential to become one of the strongest Paramecia abilities.
Long before arriving in Alabasta...
The Bomb-Bomb Fruit had already been one of the abilities Kaito wanted most.
The reason was simple.
Its upper limit was unimaginably high.
Back in his previous world...
Even a nuclear explosion was fundamentally just another form of explosion.
Whether the Bomb-Bomb Fruit could eventually reach that level remained impossible to determine.
Even so...
Using a nuclear explosion as a reference alone demonstrated just how limitless this Devil Fruit's potential truly was.
Since even exhaled breath can carry explosive properties...
Then what about this...?
A new thought surfaced in Kaito's mind.
He immediately drew one of his golden sabers.
Without hesitation...
He swung it.
A flying slash shot toward the sea not far away.
Boom!!
The flying slash itself wasn't particularly large.
But the instant it struck the ocean...
Something entirely different happened.
Instead of merely splitting the sea...
A tremendous explosion erupted from the point of impact.
A deafening roar echoed across the ocean.
The explosion possessed power no less than Kaito's earlier punch delivered while weighing ten thousand kilograms.
Massive waves surged across the sea.
The water churned violently.
Another enormous whirlpool quickly formed amidst the aftermath of the blast.
