"Bang bang..."
"Boom...boom..."
"Hey... Chi Chi..."
In the chaotic forest, two incredibly fast figures clashed repeatedly.
"Thirty million volts Thunderbird!"
Intense bursts of electric light kept flashing, illuminating the area in a dazzling, pale glow.
The heroic Smoothie held a long sword, her entire form bathed in the bright, crackling electric light.
"Hey..."
With a wave of her left hand, a massive thunderbird condensed into existence—vivid and lifelike.
It flapped its wings and charged towards Wilhelm with the speed of lightning.
"Brush!"
Wilhelm's silver hair flew as he moved with lightning speed.
In an instant, he leapt into the air, narrowly avoiding the thunderbird's fierce assault.
Using his well-honed Observation Haki, he locked onto Smoothie's position.
"Flying Blade and Blood Claw!"
His five fingers transformed into sharp claws, shimmering with cold steel, and slashed forward with deadly precision.
"Shhhhh..."
Multiple crimson claw blades materialized mid-air, each imbued with flowing Armament Haki that resembled cherry blossoms.
The clash was fierce—the atmosphere rippled and shattered under the force.
"Keng, Keng..."
Sparks flew, the sound of metal clashing rang out.
Smoothie, wielding her sword, blocked each strike with precise, calculated movements, guided by her awakened Observation Haki.
"Hey!"
She shifted with a burst of lightning, reappearing in front of Wilhelm in an instant.
Her enormous sword surged with electricity, wrapped in freshly activated Armament Haki, and she slashed down with brutal force.
"Keng!!"
The clash of steel and lightning resounded through the air.
Despite the powerful electric shock, Wilhelm's unshakable right hand withstood the force, immune to the surge.
"Not bad..." Wilhelm smirked, but did not let up.
In an instant, his hands transformed into sharp, clawed strikes, infused with pitch-black Haki and crackling with electric currents.
He stormed forward toward Smoothie.
Unlike his usual swordsmanship or Paramecia abilities, Wilhelm relied solely on raw physical strength, pushing his limits to match Smoothie's heightened power from the Logia Thunder Fruit.
"Clang...clang..."
Electric light and sparks flew as their weapons collided, creating an intense display of energy.
The lightning in the sky crackled intensely, blinding anyone who dared to look directly.
In the blink of an eye, the two had exchanged dozens of strikes.
Thanks to her newly acquired Logia Thunder Fruit, Smoothie's Observation Haki had evolved to a level where she easily read Wilhelm's dizzying, relentless attacks.
Even in the face of his overpowering, rapid movements, Smoothie was in complete control—her skill had elevated her beyond anything she was before.
"Tsk tsk, it's like a completely different person!"
"Indeed, she's a powerhouse now, far more formidable than before!"
Witness this incredible confrontation.
From a distance, Strong and Simon stood side by side, arms folded, their eyes fixed on the battle with a mixture of awe and amazement.
Though Wilhelm lacked the power of a Devil Fruit or any sophisticated swordsmanship, his raw physical prowess was undeniable.
Smoothie, only sixteen years old, had managed to endure the fierce onslaught so far, which was no small feat.
Not everyone possesses such extraordinary talent. Wilhelm's innate abilities—his enhanced durability, strength, and tactical brilliance—far outstripped the average, making him a formidable opponent even without a Devil Fruit.
While Smoothie's newfound Logia Thunder Fruit greatly enhanced her abilities, it was clear that Wilhelm's innate, unyielding strength complemented her power perfectly.
Their bond as siblings, forged through years of close ties, only strengthened their unity on the battlefield.
Strong and Simon watched in silence, feeling a complex mix of admiration and envy. Strong, though grateful for Wilhelm's intervention in securing her Paramecia ability, still yearned for greater strength.
Similarly, Simon, who lacked any fruit abilities entirely, couldn't help but wish for something more suitable to her unique talents.
"Brush—"
Smoothie's reflexes were sharper than ever. Her transformation into lightning allowed her to evade Wilhelm's piercing claws in the nick of time.
The destructive force left a deep, terrifying gash in the earth, sending up clouds of dust and debris.
"Boom..."
The ground trembled as Wilhelm's devastating attack ripped through the landscape, creating a chasm in its wake. His physical power was unparalleled, even against her enhanced Logia form.
"Sigh, chirp..."
"Sixty million volts Thunder Beast!"
Smoothie roared, conjuring a massive Thunder Beast from the intense electric light. The beast roared as it lunged at Wilhelm with terrifying speed and ferocity.
Without hesitation, Wilhelm responded with a powerful move.
"Tempest Kick Roronoa Arashi Bird!"
His right leg kicked forward like a blade, slashing through the air with a vacuum force that created a massive, razor-sharp flying bird. It rushed to intercept the charging Thunder Beast.
"Boom..."
The collision was deafening. The resulting explosion of energy sent shockwaves rippling across the battlefield, devastating the surrounding area.
The air became thick with dust, and the debris made it impossible to see clearly.
"God's Judgment!"
Almost immediately, the sky erupted with intense lightning.
A colossal thunder pillar, over ten meters wide, descended from the heavens with devastating force.
"Hoo—"
The thunderous roar shook the very earth beneath them, its destructive energy crashing down upon Wilhelm without mercy.
It was a sight that left no doubt—a display of godly power, merciless and overwhelming, as if punishing all those who dared oppose it.
"Brush!"
However—
"What!?" Smoothie's eyes widened in disbelief.
In an instant, Wilhelm's figure transformed into pure electricity, leaving behind only a fleeting afterimage.
In the blink of an eye, he materialized right before her.
"Whoosh—"
His wrapped Armament Haki-enveloped right leg soared high into the air, descending with a devastating force from top to bottom.
"Keng!!" A deafening clash echoed through the air as Smooth barely managed to block the brutal strike with her long sword.
The sheer force behind Wilhelm's attack pressed her back, forcing a subtle change in her expression.
In the next heartbeat, she was sent hurtling toward the ground like a lightning bolt.
"Hey..." Smoothie's voice was strained as she fell rapidly, only to immediately transform into lightning mid-air.
"Boom..."
The ground shattered beneath her impact, sending up a cloud of dust and debris.
From the crackling chaos, her lightning-infused figure reappeared, slightly disheveled but unharmed. The elementalization had successfully nullified the majority of Wilhelm's overwhelming force.
"Sixty million volts Thunder Beast!"
Smoothie's eyes burned fiercely with determination. Her voice was steady, but there was a noticeable effort in her movements. The intense lightning swirled around her, forming a majestic and radiant aura, as if she were a Valkyrie of thunder.
Staring down Wilhelm in mid-air, she began to gather even more powerful energy. The intensity of her lightning surged toward her limit—a hundred million volts.
"Let's call it a day!"
Wilhelm's voice was calm as he floated down onto the ground, observing Smoothie with a soft smile. His praise was genuine. "This fruit is truly fitting for you, Sister Smoothie."
"In less than three days, you've already developed such devastating combat abilities."
"Thank you, Wilhelm!"
Smoothie's gratitude was evident. Her breathing was heavy, but her smile was genuine. "Without your guidance, I wouldn't have been able to refine those moves so quickly."
The growth she had achieved with the Thunder Fruit was staggering. Each clash with Wilhelm helped her push her abilities further, but she was aware of how much her brother's skill and support played a role.
"It's mainly because Sister Smoothie, your talent is exceptional!" Wilhelm chuckled warmly.
Despite his guidance, Smoothie's rapid mastery of her abilities impressed him. She had a natural aptitude, reminiscent of their brother Katakuri's own brilliance.
"I believe with time and experience, your strength will surpass even my expectations."
Wilhelm's voice held pride as he regarded her.
After staying on Sky Island for a while, it was time for both of them to leave.
"Sigh..."
The electric light began to fade, leaving only the calm aftermath of their intense battle.
"Let's go."
Smoothie nodded, her gaze steady as they prepared to set sail once more.
