When a God of Destruction Was Reincarnated in Tensura:

Azazel stood at the center of devastation. He had won.

The Demon Lords lay broken across the battlefield, their once unstoppable wills shattered under his relentless might. Blood stained the ground where Guy Crimson, Rimuru Tempest, Milim Nava, and the others lay. Their bodies twitched, barely able to move.

Azazel sighed, rolling his neck.

"That was… underwhelming."

His wings of pure abyss stretched wide, blotting out the heavens. The once-thriving world of the Cardinal Realm had been reduced to ashes and ruin. Only one place remained untouched.

Azazel's cold, golden gaze drifted towards Blumund.

A strange barrier shimmered around the city—untouched, unscathed, pristine.

He scoffed.

"So, this little city still stands?"

His clawed hand stretched forward.

A spear of condensed abyssal destruction formed in his palm, radiating enough energy to erase entire star systems. With a casual flick, he hurled it toward the barrier.

BOOOOOOM!!!

The world shook. The clouds split apart. The ground tore open. The Demon Lords, barely conscious, felt the impact even in their battered states.

And yet—

The barrier remained.

Not even a crack.

Azazel's expression darkened.

"What?"

He extended his hand again, this time summoning a planet-destroying vortex, condensed into a singularity.

He unleashed it.

BOOOOOOOOM!!!

And still—

Nothing.

No cracks. No distortions.

Blumund stood untouched.

Azazel's laughter cracked through the air like thunder.

"Hahahahaha… No. No, no, no… this doesn't make sense. I AM THE END! I AM ABSOLUTE! NOTHING CAN DEFY ME!"

His eyes burned with abyssal rage.

"I WILL ERASE THIS PATHETIC CITY!!"

He raised both hands, summoning the full might of his divine destruction. A sphere of death the size of a moon formed above him, ready to erase Blumund from reality itself.

The people inside the city trembled in fear. They watched in horror, knowing that their fates were no longer in their own hands.

Yet, the barrier did not waver.

Whis, who had been silently observing the battle, finally spoke.

"Lord Beerus… this barrier… what is it?"

Beerus smirked, taking a sip from his drink as if this entire war was mere entertainment.

"Ah, that? It's simple. I held a tournament long ago. Blumund won. Their wish?"

He turned his gaze toward the struggling Azazel, who was growing more furious by the second.

"A barrier around their country that no one—not even a god—can destroy."

His wives, Velzar, Erza, Zerna, Delta, Beta, and Sigma, all looked at him.

Whis's voice trembled slightly.

"And you… just granted that?"

Beerus shrugged.

"Of course. A wish is a wish."

Sigma clenched her fists.

"Even Azazel… even he can't break it?!"

Beerus chuckled.

"Nope. I made it, after all."

Whis's eyes narrowed.

"Then… what happens now?"

Beerus placed his drink down, stretching lazily.

"Well, I suppose this little game has gone on long enough."

He raised one hand.

And with a single, effortless motion—

Reality itself tore apart.

A gaping void opened in the skies above the battlefield.

The Cardinal World trembled violently.

The Demon Lords, barely clinging to life, felt it instantly. Their souls screamed in terror, their instincts telling them something had arrived that should not exist.

Rimuru, despite being near unconscious, shuddered uncontrollably.

"Wh…What…is…this…?"

Milim, blood dripping from her mouth, tried to lift her head but failed.

"It…hurts…"

Guy Crimson, the strongest Demon Lord, known as the Lord of Darkness, clenched his shaking fists.

"This…this presence…!"

The world darkened.

The sky broke apart, splitting into a fractured abyss of swirling black and crimson.

Azazel froze.

His golden eyes flickered with confusion, then realization, then… something else.

Fear.

"What… is this…? WHO… IS THIS?!"

From the depths of the void, a being stepped forward.

A presence beyond the concept of strength itself.

"You have overstayed your welcome, Azazel."

A voice deeper than the abyss, echoing power beyond comprehension.

And then—he stepped forth.

A figure clad in absolute darkness descended.

His form was both real and unreal, shifting between the planes of existence. His armor was crafted from the void itself, pulsing with endless destruction and boundless creation.

His eyes—glowing pools of pure entropy—stared at Azazel with disdain.

"I am Nyxion, Emperor of the Abyss. Leader of the Twelve Zodiacs."

Each step he took made the world crumble.

The mere weight of his presence made the air suffocating. The very concept of existence around him warped, twisted, shattered.

Azazel, the one who had just humiliated the Demon Lords, the embodiment of despair itself, took a step back.

"N-No…this is wrong…!

Nyxion's voice was cold, absolute, final.

"You believe yourself to be the end. You are nothing."

He raised a hand, and the entire Cardinal World screamed in agony.

Azazel clutched his chest, feeling something he had never felt before.

Pain.

His wings trembled. His aura flickered.

For the first time in eternity—he doubted his own strength.

Back in the Heavens, Beerus stretched, letting out a lazy yawn as if the entire spectacle before him was nothing more than a passing amusement. His golden eyes flickered with interest as he observed the battlefield below—where Nyxion, the leader of the Zodiacs, had finally descended.

The world itself seemed to suffocate under Nyxion's presence. The sky was nothing but fractured void, the land weeping in despair, and even the winds refused to move, afraid of disturbing the stillness that had fallen upon reality.

Whis, always composed, but now with a rare hint of tension in his voice, glanced toward Beerus.

"Lord Beerus… who exactly is this?"

Beerus smirked, his tail lazily flicking behind him.

"Ah, that? That is Nyxion. The leader of my Zodiacs."

His words sent a cold chill through the air.

Velzar, standing nearby, narrowed her eyes.

"The leader…? You mean he's above the rest of the Zodiacs?"

Beerus grinned, his fangs glinting slightly.

"Oh, far above."

A long silence settled between them.

Erza crossed her arms, watching as Nyxion took a single step forward—and with just that movement, the very laws of existence around him seemed to break apart.

She clenched her fists.

"Just how strong is he?"

Beerus exhaled slowly, his expression unreadable.

"Stronger than all the other Zodiacs."

The air grew colder.

Zerna's eyes widened in shock.

"That's… impossible. You said the Zodiacs were the apex of power. Each one surpasses the concept of strength itself. And now you say this one is even beyond them?"

Beerus nodded casually.

"Exactly."

Delta's voice came out shaky, her usual arrogance nowhere to be found.

"Then what does that make him?"

Beerus chuckled darkly.

"The finality of power. The peak beyond the peak."

Sigma, who had remained silent until now, finally spoke.

"Lord Beerus… did you create him?"

The question hung in the air like a blade pressed against fate's throat.

Beerus' smirk grew wider, but there was something ominous behind it.

"Yes. I did."

The simple admission sent shockwaves through them.

Whis blinked, genuinely surprised.

"You… created something like this? But why?"

Beerus closed his eyes as if recalling an old memory.

"Because I thought it would be wise to have an army… for work like this."

Velzar's throat went dry.

"Work like this…? You mean situations where you don't want to step in personally?"

Beerus opened one eye, looking at her with bored amusement.

"Exactly. Why should I dirty my hands when I have something that can do it for me?"

His words sent a shiver of dread through them

Zerna took a deep breath, steadying herself.

"Then tell us, Beerus… what is Nyxion?"

Everyone turned toward him, waiting for an answer.

Beerus' smirk faded slightly. His golden eyes flickered, looking down at Nyxion, who stood before Azazel—a being who was supposed to be unstoppable, now trembling for the first time in his existence.

And then Beerus spoke.

"Nyxion is both existence and void. He is the beginning and the end, the space between reality and the abyss."

His voice was devoid of humor, and the weight of his words crushed the very air around them.

Delta took an uneasy step back.

"Existence and… void…?"

Beerus nodded.

"He is not a god, nor a demon, nor a force of nature. He is the embodiment of that which should not be. A paradox made flesh. A walking contradiction that should not exist, yet does."

Whis narrowed his eyes, realizing something terrifying.

"That would mean… he is beyond even conceptual destruction. He cannot be erased."

Beerus chuckled, resting his chin on his hand.

"You're starting to get it."

Sigma's hands trembled, her entire body rejecting what she was hearing.

"That's… that's madness… something like that shouldn't exist…"

Beerus turned toward her, his grin widening into something almost sinister.

"And yet—he does."

Silence fell again.

Nyxion had arrived.

And all of existence was about to witness what true despair looked like.
