Killed For 100 Years in Hueco Mundo, Aizen Invited Me To Soul Society!

Chapter 388 - 387: The Crimson Domain

After Mazuru’s quiet declaration, the dead screen that had been black for so long began to bleed with color.

A slow, seeping crimson spread across it like blood soaking through paper, replacing the darkness. The command center inside Las Noches fell silent as the hue thickened—red swallowing black, pulsing faintly with reiatsu.

Kenpachi Azashiro immediately sensed it. The moment Mazuru’s reiatsu flared on the far end of the square, he knew.

’He’s entered the field.’ Azashiro thought grimly.

Within the choking mist of the Gift Bereich, Askin’s laughter echoed. His halo spun faster behind his head as he looked at Ulquiorra, who was forcing his way forward step by step, his movements sluggish but unbroken.

"Haha! So even with that fancy second-stage Resurrección," Askin jeered, "you can only temporarily boost your reiatsu. You might’ve escaped my first set of lethal parameters, but what about now?"

His grin sharpened. "In here, every second you breathe brings you closer to death!"

He spread his arms theatrically, his molecular halo rotating behind him like a glowing mandala of chemistry. "Can you feel it? The paralysis crawling into your limbs? The suffocation biting at your lungs? Even your High-Speed Regeneration can’t save you from this!"

Askin’s voice rang out, half triumphant, half insane.

Ulquiorra said nothing. The toxin gnawed at his muscles; every movement tore through agony, every breath a dagger. But he endured.

He always endured.

Slowly, deliberately, he lifted his arm. The space in front of him shimmered—Reiatsu condensed, coalescing into a spear of pure emerald lightning.

"Lanza del Relámpago."

The Thunder Spear. His ultimate strike in Segunda Etapa—a technique born the very first time he transcended his limits in battle. Back then, against Kurosaki Ichigo, he had misjudged it—his inexperience cost him precision. But now... now there was no hesitation.

He released it.

The spear of thunder shot forth like a beam of light, tearing through the poison-thick air, its descent splitting the blackness like divine judgment.

*Zzzzzrrrttt—BOOOOM!*

Askin’s eyes widened. He hadn’t expected Ulquiorra to muster such force within his own death field. The calculation didn’t add up.

But it was too late for retreat.

He raised his hand, conjuring an enhanced Heilig Pfeil, a light arrow amplified by his Vollständig. The reishi condensed instantly, swirling into a blinding bolt.

"Let’s see whose physics wins!" he snarled, firing.

*BOOM!!*

Light met lightning. Reishi collided with spiritual thunder, and the shockwave detonated through the entire domain. The lethal gases scattered under the force, waves of pressure slicing apart the black mist.

For a heartbeat, the two forces seemed equal—but then the Thunder Spear shattered the arrow, plunging straight through and striking Askin head-on.

*Crash!*

The explosion lit the domain in green fire.

Ulquiorra lowered his arm slowly, his body trembling from the effort. The air still burned with ozone. He watched the smoking impact zone, his voice a whisper.

"...Is it over?"

He didn’t move. Couldn’t. The poison density around him—Askin’s deliberate trap—was at its peak. His lungs screamed for air, every organ rebelling against the toxins saturating them.

And then the smoke cleared.

Ulquiorra’s pupils narrowed.

Askin stood. Barely—but he stood. His body was half-burned, the molecular halo behind him flickering, but still intact.

He coughed blood and then laughed weakly. "A little closer... just a little closer, and you’d have killed me!"

He chuckled darkly. "If I hadn’t used Blut Vene, in that last instant, that would’ve been the end. But you see—" he straightened slightly, grinning wider "—as long as you don’t kill me the first time, my holy body will always heal."

The burned tissue along his arm shimmered, reforming before Ulquiorra’s eyes. The arrogance in his voice rose with every heartbeat.

"Now, it’s your turn to die!"

A glowing Heilig Pfeil formed once again between Askin’s fingers, brighter and sharper than before. Without hesitation, he released it, the arrow screaming toward Ulquiorra’s chest.

The shot was perfect. There was no room to dodge.

And then—a crimson shimmer appeared.

A circular light shield materialized in front of Ulquiorra’s body, intercepting the arrow midflight.

*Kshhhh!*

Sparks flew. The projectile disintegrated harmlessly.

Askin froze.

A pulse of unfamiliar reiatsu washed over him. The poisonous air around them rippled like water disturbed by a thrown stone.

From within the haze, a figure began to take shape—first as a silhouette, then in full form, cloaked in red and gold light.

Askin’s eyes widened. "You—"

His voice dropped to a whisper. "The King of Hueco Mundo... Kyo Mazuru."

He recognized him immediately.

The Wandenreich had kept records. Hidden deep under Seireitei for centuries, they had observed everything—every captain, every secret. Before his defection, Mazuru had been one of their key watch targets, a captain whose reiatsu had been deemed "unstable but dangerous".

Then came Aizen’s rebellion—and, astonishingly, Mazuru’s. The former captain had vanished, resurfacing as the new ruler of Hueco Mundo.

And now, standing here, inside his own Gift Bereich, Mazuru was more terrifying than any report could have captured.

Askin forced a grin. "So, witnessing your subordinates broken and bleeding, you finally show yourself, huh?"

He laughed hoarsely, trying to steady the shake in his hands. "But it’s too late. Inside my Poison Domain, you’ll die just like the rest!"

He wasn’t lying to himself. The orders from Yhwach had been clear: test the potential of the Hueco Mundo alliance. If it proved useful, use it. If not... eliminate it.

After this battle, Askin had already made up his mind. The Espada were strong, yes—but not Wandenreich strong. Not enough to warrant an alliance.

No—Hueco Mundo would make better cannon fodder.

He would kill the "King" himself and enslave every hollow that remained. The idea filled him with twisted satisfaction. A shinigami ruling the hollow world was blasphemy enough; exterminating him would be poetic justice.

He sneered. ’Once you’re dead, we’ll turn your whole desert kingdom into our army.’

Mazuru tilted his head slightly, crimson eyes calm, almost pitying. "Your Poison Domain?" he repeated. "Sorry—this has already become mine."

"What—?"

Before Askin could process it, he saw it. The purple fog around them began to change color—slowly at first, then rapidly.

The poison bled red.

Like veins filling with blood, the entire sphere turned crimson. The molecular structures in the air flickered, destabilizing. The toxic pressure that had defined the domain began to collapse in on itself, dissolving into harmless light.

The suffocating poison vanished.

Askin’s eyes went wide. "W-What did you do?!" he demanded, voice cracking as he felt his control slipping. The molecular halo behind his head faltered, flickering violently.

Mazuru raised his hand slightly, palm facing the ground, as if weighing the air.

"What did I do?" His tone was soft, almost bored. "I simply covered your domain."

The red light intensified, devouring the last traces of Askin’s black mist.

"You see," Mazuru continued, stepping forward, "even among enchantments, there are hierarchies—dominance and subordination. Your domain sits lower. Mine supersedes it."

He extended one hand, resting it lightly against the invisible wall of the world Askin had made.

"And this ground..." he said quietly, "now belongs to my domain."
