Battling the Three-Digit Arrancar (Four)

"Roar--!"

As Gantenbainne's the Roar, filled with draconic might, fell, the energy torrent that had gathered in the center of his clasped dragon claws—the "Dragon Fist," a fusion of violent Reiatsu and destructive lightning—finally broke free of its restraints. It transformed into a ferocious, the Roar yellow energy dragon, tearing through the air with terrifying power that could annihilate everything in its path, and hurtling straight towards Yasutora Sado!

The air was compressed into a visible white shockwave, and the ground was plowed with scorched furrows by the aftershocks of the dissipated energy. This attack was devoid of any fancy moves; it was purely the ultimate condensation of power and destruction, a wild outpouring of the primal power after the Arrancar's Resurrección!

Faced with this unavoidable, deadly attack, Yasutora Sado, which were always as calm as a deep pool, ignited for the first time with a fierce fighting spirit that seemed to set him on fire. He did not retreat, nor did he dodge; he simply raised the "Giant's Right Arm," which symbolized "protection" and "the power of the earth," heavily and firmly, and held it across his front.

Thump!

The massive crimson gauntlets were deeply embedded in the ground, with jagged bone spikes standing upright on the gauntlets. Dark red Reiatsu, like boiling lava, flowed and formed wildly on the surface of the gauntlets, instantly creating an incredibly thick Reiatsu barrier with ancient, savage patterns engraved on its surface. This was not just defense, but an absolute declaration of protection based on the earth!

The next instant, the torrent of "Dragon Fist" energy slammed solidly into the scarlet shield!

"Boom--!"

The deafening explosion reverberated throughout the Warehouse area, even drowning out all sounds from other battlefields in the distance! A blinding yellow-white light erupted instantly, completely engulfing the location where Yasutora Sado was standing!

The raging energy turbulence, like a runaway tsunami, swept wildly in all directions, tearing up and shattering the already devastated ground once more! Thick white smoke, a mixture of Reishi ash and building dust, rose like a mushroom cloud, completely obscuring Yasutora Sado's figure.

Gantenbainne lowered the dragon claw that had been blocking his view and protecting him from the shockwave, and adjusted the eye patch on his forehead, which had become slightly askew from the violent explosion.

He was panting, his chest rising and falling slightly from the rapidly depleted Reiatsu after Resurrección, but his dragon eyes were fixed on the swirling, thick smoke and dust. Deep in his pupils was both absolute confidence in the power of his "Dragon Fist" and a hint of barely perceptible tension and anticipation.

He believed that no defense could withstand his full-force "Dragon Fist" head-on unscathed, but that human boy who kept creating the Miracles always brought unexpected "surprises."

The smoke and dust, carried by the aftershocks of the energy, began to slowly flow and settle.

First to emerge from the edge of the smoke and dust was a deep, solid, dark red outline, like an ancient rock—the edge of the shield formed by Yasutora Sado's "Giant's Right Arm." Then, the full shape of the shield gradually became clear.

It was thicker and larger than before, and its surface was no longer a smooth condensation of Reiatsu. Instead, a faint relief of a ferocious face, full of primal majesty and indomitable will, emerged! The face had its eyes closed, like a sleeping ancient giant, exuding a chilling aura of protection.

At the edge of the shield, dark red Reiatsu rippled slowly like a living thing, repairing the tiny cracks caused by the impact of the "Dragon Fist".

The moment Gantenbainne saw the shield-like face, his heart skipped a beat! A primal, instinctive apprehension of a higher level of "protection" crept into his mind. This shield... it wasn't just defending against physical and Reishi impacts; it seemed to be resisting any "concept" that attempted to harm what lay behind it!

As the smoke and dust continued to dissipate, Yasutora Sado's tall and composed figure, like a giant emerging from ancient mythology, remained perfectly intact after the dust settled.

His right arm hung slightly, the menacing shield still faithfully protecting him. The face relief on the shield seemed to open its eyes slightly in the flowing light, glancing at Gantenbainne before slowly closing them again.

Yasutora Sado slowly raised his head, looking at the astonished Gantenbainne. His voice was still deep, but it carried an unprecedented clarity and insight, as if stating a truth that had just been confirmed by his own soul:

"Ever since I began to truly understand and accept the power residing in the right arm, the 'Giant's Right Arm' has clearly shown me its essence—it is the power of protection. It is a 'shield' rooted in the earth, drawing strength and resilience to build an absolute barrier for those behind it."

He changed the subject, his gaze falling on his left hand hanging at his side. "So, since my right hand symbolizes 'protection,' where is my 'attack,' my 'spear'? This question has troubled me for a long time."

His left hand, fingers slightly curled, as if sensing something. "Until... I arrived in Hueco Mundo. I felt that deep within my body, there had always been another, completely different power lurking."

It was restless, excited, and filled with a destructive desire, as if Yuzu had returned home to the environment most suitable for its release. Every time I tried to guide it, its overly intense 'excitement' made it difficult to control, and the slightest carelessness could backfire.

Yasutora Sado's gaze sharpened as he looked at Gantenbainne, as if thanking this powerful opponent, "And the battle with you, especially the moment I took your 'Dragon Fist' head-on... that violent power seemed to be 'soothed' and 'resonated' by a power of equal strength, finally settling down from its chaotic frenzy and revealing its true form to me."

As he said this, he slowly raised his left hand.

At first, nothing seemed amiss. But then, tiny, pure white, liquid-like electric sparks suddenly danced at the tips of the five fingers! These sparks were not the lightning of nature or the Kidō; they were more condensed and more violent, carrying a pure will of "collapse" and "penetration"!

Yasutora Sado clenched his fist tightly!

"Sizzle--!"

A burst of pure white lightning erupted instantly, like living vines, rapidly spreading and coiling along his arm! Wherever the lightning passed, a more fundamental power seemed to be awakened and shaped beneath the skin of his arm. In the blink of an eye, his entire left arm, from fingertips to shoulder, was covered by a layer of pure white, smooth "armor" that seemed to be made of the purest energy crystals! The armor had smooth lines and was full of power. Sharp white bone spurs protruded at the joints of his elbows and shoulders. Especially on the shoulder armor, a blood-red, sharp horn that seemed to pierce the sky stood proudly, exuding a chilling piercing intent! His entire left arm was completely different from the dark red and heavy right arm, presenting an extreme beauty of "sharpness," "swiftness," and "destruction."

"The Left Arm of the Devil"—this is the name Yasutora Sado gave to this newly awakened power.

The instant Chad's left arm underwent its transformation, Gantenbainne sensed an extremely dangerous, sharp aura that seemed capable of piercing through Chad's dragon scale defenses after his Resurrección! Without hesitation, his feet Sonído, and his figure vanished from his original spot, appearing behind and to the side of Yasutora Sado. His dragon claws, covered in thick scales, clenched tightly, and his earth-yellow Reiatsu condensed into a cone, launching a swift and fierce attack on Chad's seemingly unguarded left rib!

However, this time, Yasutora Sado's reaction was faster than anyone could have imagined!

He didn't even turn around; his left arm simply reached backward at a speed and angle that defied the natural laws of joint movement!

"Smack!"

A crisp sound.

His left hand, covered in pure white crystalline armor and crackling with white lightning, surprisingly struck first, firmly and precisely grasping Gantenbainne's dragon claw wrist, powerful enough to shatter steel! The moment the white lightning touched the yellow Reiatsu, a sizzling sound of corrosion emanated from it, and the Reiatsu cone condensed on Gantenbainne's fist was easily "disintegrated" and "dispersed" by the white lightning!

Gantenbainne was terrified! He tried to pull his hand away, but found that his wrist was locked firmly in place by the strongest Reishi alloy clamps, unable to move an inch! Yasutora Sado's left hand had a different kind of power than the heavy and powerful right arm; it was an extremely condensed, penetrating, and controlling grip that was terrifying!

Immediately afterwards, Yasutora Sado twisted his waist and flicked his left hand upwards!

"Whoosh--!"

Gantenbainne's massive body, after its Resurrección, was as light as a rag doll. Yasutora Sado easily swung it up with one hand, tracing a semi-circle, and then hurled it hard into the open space in the distance!

"Boom!"

Gantenbainne crashed heavily to the ground, he rolled more than ten meters before barely regaining his balance, leaving a deep furrow in the ground. He knelt on one knee, looking at Yasutora Sado with a mixture of shock and anger. A tingling and stinging sensation came from his left wrist, a sign that the white lightning was corroding his spirit body and interfering with the flow of Reiatsu.

Yasutora Sado slowly retracted his left arm, the pure white crystalline armor gleaming coldly in the dim light. He looked at Gantenbainne and continued, "Now, I finally understand. The right arm is a 'shield,' drawing upon the power of the earth to protect my companions and myself; the left arm is a 'spear,' drawing upon the sharpness of the void (Hueco Mundo) to pierce through all obstacles and enemies. Only when the two are combined can one be—"

Before he finished speaking, his figure had already vanished from the spot!

It wasn't Shunpo, nor Sonído, but a more direct and uncanny speed closer to "spatial leap"! It was the ultimate mobility bestowed upon him by the "Left Arm of the Devil," designed specifically for "attack"!

Almost the instant that Gantenbainne raised his head, Yasutora Sado, covered in pure white armor, carrying a piercing electric shriek and compressed pure white Reiatsu, slammed into his abdomen!

"The Demon’s Strike."

Yasutora Sado's deep voice rang out simultaneously with the dull thud of a fist striking flesh.

"Puff--!"

There were no exaggerated energy explosions, no dazzling light effects.

There was only a dull, muffled sound, as if power had been completely "infused" rather than "released."

Gantenbainne's eyes bulged instantly, his mouth gaped open, but he couldn't utter a sound. He felt an indescribable, pure, and utterly destructive force, like the finest needles or an indestructible drill, easily tearing through his dragon scale defenses and muscle fascia, ruthlessly rushing into the depths of his spiritual body, rampaging and destroying his internal organs, bones, and even Reiatsu circuits! All defenses were rendered useless before this power!

His body, like a puppet with its strings cut, was thrown backward by the punch and slammed hard into the already battered concrete wall behind him.

"Thump!!"

After the dull thud of the impact, came the sickening sound of the wall shattering.

However, this time, the walls around the impact point did not simply dent or crack. Instead, under the spread and erosion of the residual power of the "Demon Strike," a huge, clear, and edged-within-a-line white electric arc relief of a demon's face appeared, centered on the impact point! The face was ferocious and angry, like a gaze from the abyss, deeply imprinted on the wall, silently proclaiming the "conceptual" erosive power contained in this strike, which transcended physical destruction!

Gantenbainne's body slowly slid down from the wall with the demon's face printed on it and collapsed to the ground.

The Reiatsu surrounding him from his Resurrección rapidly diminished and dissipated like a deflated balloon; his dragon horns, claws, scales, and other features quickly faded away, restoring him to the form of an ordinary Arrancar.

He struggled to stand up, but only coughed up several mouthfuls of dark liquid mixed with Reishi light particles in vain. His eyes were unfocused, and he had clearly lost all fighting ability.

Yasutora Sado slowly withdrew his fist. The pure white crystal armor and white electric sparks on his left arm receded like the tide, restoring his normal arm appearance. He glanced at the Gantenbainne, then looked down at his own hands—his right arm was dark red and as heavy as a mountain; his left arm had (temporarily) returned to normal, but a trace of pure white electric sparks seemed to remain at his fingertips.

"Shield and spear..." he murmured to himself, a flash of understanding in his eyes. This fierce battle with the Espada Fracción not only allowed him to completely master the "Giant's Right Arm," but also unexpectedly awakened and initially controlled the corresponding "Left Arm of the Devil." His power system was finally complete.
