Though the laws of physics in this world were slightly different, after several attempts, Shermie finally managed to reproduce the move from the story Sherwin had told her.
The small forest cat projectile, driven by electromagnetic force, turned into a streak of orange light, shooting toward the still-hesitating Doflamingo at lightning speed.
"Damn it!"
Having been momentarily distracted, the Heavenly Yaksha realized through Observation Haki that it was already too late to dodge.
In that split second of danger, he no longer cared about hiding his trump card and directly activated his fruit awakening.
The ground beneath his feet suddenly surged like waves, rapidly transforming into countless white threads.
"Shield White Line!"
Layers upon layers of shields made of white threads formed in front of Doflamingo.
"Boom—!"
The orange electromagnetic cannon slammed violently into the Shield White Line, erupting in a deafening explosion.
Blinding flashes of lightning and scattered threads filled the air, obscuring Doflamingo figure.
Yet, through Sherwin Observation Haki, he sensed that his opponent was still largely unharmed...
So the power of a Devil Fruit after awakening really was formidable.
Sensing the same thing, Shermie pulled out a cloud shell, tossing it high into the air with her elementalized paw.
The shell shot upward and soon released a thick mass of dark clouds across the sky.
Fleet Admiral Sengoku, who had rushed out with the others to witness the fight, suddenly turned pale.
He shouted at the top of his lungs to the nearby marines drawn by the commotion:
"Quick! Everyone, move away from the battlefield—now!"
The prestige of Fleet Admiral Sengoku was still formidable. At his command, the nearby Marines quickly retreated from the battlefield.
Immediately after, they saw thunderclouds gather above Marineford. From within the clouds, a massive beast of lightning — part horse, part deer — thrust its head out before descending from the sky with a thunderous force.
"Lightning Release: Kirin Meow!"
It seemed Shermie really hated Doflamingo. This Kirin was far larger than the one she summoned a few days ago… after all, this one had been specially enhanced using a Cloud Dial.
"Sea Field: White Wave!"
The area affected by Doflamingo awakened Fruit ability expanded even further.
Not only the ground beneath them but even the surrounding buildings were transformed into giant waves made of threads.
Those waves, wrapped in jet-black Armament Haki, surged upward to clash with the thunderous Kirin descending from the heavens.
"BOOOOM!!!"
As the Kirin collided with the massive tidal wave of threads, an even greater explosion thundered through more than half of Marineford.
Once again, neither side gained the upper hand.
The Rumble-Rumble Fruit power was indeed immense, but the Heavenly Yaksha Armament Haki and awakened ability were no less formidable.
However, while Shermie attack was a single charged strike, Doflamingo had simultaneously unleashed his awakened Fruit ability and infused countless threads with Haki — a tremendous drain on both stamina and focus.
Although pirates of his caliber could fight for days without rest, the Heavenly Yaksha clearly couldn't tolerate being on the defensive for so long.
"White Line Tsunami!"
After blocking the Kirin, the Heavenly Yaksha immediately counterattacked, sending wave after wave of white thread crashing toward Shermie.
Crackle.
Shermie once again turned into lightning and effortlessly slipped through the gaps between the white waves.
However, under the effect of the Heavenly Yaksha awakened Fruit ability, the surroundings were filled with threads transformed by him.
The moment she stopped moving, new waves of white threads, all coated in Armament Haki, would come crashing down on her.
Clearly, Doflamingo, having been forced to reveal his trump card, had decided to finish Shermie off as quickly as possible.
He could never accept being evenly matched with a small "Cat Mink," especially one who was merely the subordinate of Sherwin — who was about to become a Warlord of the Sea like himself.
"Not good," Vice Admiral Tsuru, watching from the sidelines, suddenly frowned and muttered under her breath just loud enough for Sherwin to hear, "That little cat is still too young. She fallen for Doflamingo trap."
It turned out that while the relentless white waves pressed in from all directions, Doflamingo had deliberately left a gap that led straight toward him.
Without hesitation, the little forest cat transformed into a streak of lightning and darted right at him.
Sherwin nodded to Vice Admiral Tsuru with a faint smile. "Thanks for the warning, but Shermie isn't as naïve as she looks."
"Is that so? Good then," Tsuru chuckled softly, clearly pleased by Sherwin respectful tone.
As they spoke, Shermie had already reached Doflamingo. She raised her paw and swung it toward his forehead — a lightning-charged Cat Punch bursting with electric sparks.
But just as her electrified strike landed on the Heavenly Yaksha head, his body suddenly dispersed — unraveling into countless threads wrapped in Armament Haki that coiled tightly around Shermie, binding her in place.
Doflamingo, it turned out, had secretly used his Parasite Thread Clone after blocking the Kirin strike, while his true body hid within the mass of surrounding threads.
No one knew exactly how he did it, but the clone created by those threads was so realistic that it even fooled Observation Haki.
Even Sherwin, whose senses were finely attuned to detecting auras, failed to distinguish between the two.
However, relying on his understanding of the Heavenly Yaksha techniques, he had already anticipated Doflamingo move.
As for Doflamingo real body, even Sherwin Observation Haki couldn't pinpoint it — the countless threads infused with the Heavenly Yaksha presence made it impossible to tell where he was hiding.
With Doflamingo deliberately suppressing his true aura and amplifying that of his clone, it was indeed difficult for Sherwin, whose Observation Haki had not yet reached a transformative level, to locate him.
As expected, besides "Observation Kill," other top-tier fighters had also developed techniques to deceive Observation Haki.
Having held similar ideas even before witnessing Rayleigh "Observation Kill," Sherwin silently nodded in understanding.
As for Shermie, who had been bound, he wasn't worried at all.
Though the Rumble-Rumble Fruit didn't help much with awakening Observation Haki, once it was awakened, its enhancement to the user sensory range was astounding.
Right after her awakening, Shermie Observation Haki had instantly risen to the top rank within the Investigation Corps.
According to Shermie herself, her Observation Haki functioned like an electromagnetic scan — Doflamingo disguise couldn't possibly fool her.
Meanwhile, Vice Admiral Tsuru, upon seeing Shermie trapped, turned toward Sherwin again with concern.
But when she saw both him and his Felynes watching calmly, almost as if they were waiting for the show to unfold, she finally restrained her impulse to intervene and rescue the little cat.
"Fufufufufufu! Die! Holy Bullet — Divine Execution!"
Doflamingo true body leapt out from the layers of white threads, manipulating two massive waves of lines, each imbued with highly condensed Armament Haki, and thrust them at Shermie, who was struggling to escape through elementalization.
Pff!
The little thunder cat, unable to break free in time, was pierced clean through by the Heavenly Yaksha Holy Bullet — and yet…
She continued to struggle violently.
"Hm?!"
Doflamingo immediately sensed something was wrong. Even for a Logia user who had fully elementalized, once struck by Armament Haki, it was impossible to show no reaction at all.
Moreover, aside from not using the maximum number of Holy Bullets just now, he had already gone all out.
Then, under the furious and shocked gaze of the Heavenly Yaksha, the faint electric sparks scattered around quickly gathered together, reforming into Sharmie figure.
"Hehe~ Thanks to you using your clone as a demonstration earlier, my Lightning Release: Lightning Clone Technique is finally perfected, meow~"
Sharmie dispelled the little thunder cat that was still pretending to struggle and spoke words that pierced straight into Doflamingo heart.
