When a God of Destruction Was Reincarnated in Tensura:

The battlefield had already been pushed past its breaking point. The land itself was scarred beyond recognition, cities reduced to craters, and the very fabric of reality trembled beneath the overwhelming forces clashing across the world.

But the war was far from over.

Azazel's Heralds had begun to unleash their true power, proving that they had been holding back all along. Their presence alone distorted the world, warping space, summoning apocalyptic storms, and corrupting time itself.

The Demon Lords and their allies—already at their limits—would have to go beyond everything they had ever known.

Malphas laughed, his voice an unholy storm of chaos. His body shattered apart, revealing a core of living destruction—a fusion of pure storm, fire, and entropy. He was no longer bound by physical form.

He became the storm.

Tempest itself began to collapse, the sky swirling into a monstrous vortex of lightning and hellfire.

Goku wiped blood from his mouth, his Ultra Instinct unstable.

"This guy… he's not even fighting us anymore. He's turning into a damn natural disaster."

Rimuru's mind raced. He was absorbing the damage, but even his regeneration was struggling to keep up with Malphas's attacks.

As Rimuru felt the overwhelming destruction radiating from Malphas, he made a desperate call.

"Luna," he called out in his mind. "I need more power. Not just for me—but for all of us. Can you evolve the other Demon Lords' Ultimate Skills?"

For a moment, silence. Then, Luna's voice echoed, smooth and absolute.

"I can. But power has a price. Once they accept it… they will no longer be the same, unless they are able to control it and keep their minds sane."

Rimuru clenched his fists. "We don't have a choice. I know we can do it, i will let the demon lords know."

Rimuru's voice broke through the silence, reaching every Demon Lord through thought communication.

"Listen to me! I can help evolve your skills again, but you need to stay in control. This power will be unlike anything you've ever felt before, but if you lose yourself to it, you'll become monsters no better than the Heralds."

The response was unanimous.

"We don't have a choice!" Guy's voice growled.

"Do it, Rimuru!" Milim shouted, her battle-hungry energy surging.

"If we fall here, the world is lost," Leon said grimly.

"We accept this burden," Luminous whispered.

"No more words, Rimuru. Just give us the power," Draguel said, his dragon blood roaring in his veins.

They all agreed.

And so, Rimuru called upon Luna once more.

"Luna, one last time... evolve our skills beyond their limits."

A pause. Then, her voice—calm, absolute, and filled with divine power.

"So be it."

Then, the world itself trembled.

A pulse of divine and abyssal energy surged through Rimuru's body. His Ultimate Skills began to fuse, merging into a singular force beyond comprehension.

—Azathoth, Deus Ex Machina, and Genesis Omega began to intertwine.—

His body shook, his soul fracturing for an instant, before reforming into something new.

Rimuru exhaled, his presence now overwhelming even Malphas's storm.

Goku, sensing the shift, grinned.

"You're finally getting serious, huh?"

Rimuru's eyes burned with infinite light.

"Let's end this."

Zeraphis laughed as he devoured entire portions of the battlefield, his form growing larger, becoming a walking void that consumed existence itself.

Guy wiped blood from his mouth, his crimson eyes burning with rage.

"Do you want more power?" Luna's voice echoed.

Guy spat on the ground. "Hah. You even have to ask? Of course."

The moment the words left his lips, his soul ignited.

His Ultimate Skill Azazel, The Sovereign of the Abyss twisted, cracked, and evolved into something far darker.

Skill Evolution Complete → [Apocalypse Monarch: Pandemonium]

A black crown formed above Guy's head. The world shook as his presence rewrote the battlefield, summoning a literal hellscape around them.

Zeraphis's laughter stopped.

Guy cracked his knuckles. "Oh, now you're scared?"

Then he vanished—moving faster than light—and slammed his fist into Zeraphis's core, tearing into his very existence.

Milim had been pushed back, her once overconfident grin fading as Myrrana's nightmare world enveloped everything, turning the battlefield into an endless hell of tortured souls and abyssal horrors.

"Do you want more power?" Luna's voice reached her.

Milim wiped her mouth, her eyes burning with fury.

"You're damn right I do! Give it to me!"

Her Ultimate Skill Vritra, Wrath Incarnate shattered apart, only to be reborn as something even more primal.

Skill Evolution Complete → [Calamity Sovereign: Drakaina Ragnarok]

Milim roared, and the entire sky exploded, revealing a colossal draconic form coiling around her. Her power tripled, and the mere force of her presence crushed Myrrana's nightmare realm.

Myrrana screamed, realizing she was no longer the predator.

Milim grinned. "You're in MY nightmare now!"

And then, she descended like a falling star, her punch shaking the entire continent.

Vael laughed, his divine wrath consuming the very concept of demons, threatening to erase Luminous herself.

She gritted her teeth, feeling her body crack apart under the holy purge.

"Do you want more power?"

Luminous hesitated for only a second.

Then she whispered, "Yes."

Her Ultimate Skill Lilith, Queen of Temptation morphed, becoming something even more terrifying.

Skill Evolution Complete → [Eternal Night Empress: Lilith Requiem]

The entire sky turned black. The sun was swallowed whole.

Vael's eyes widened in horror.

Luminous smirked, stepping forward as her mere presence erased divine light itself.

"Now then… how does it feel?"

Vael screamed.

Nyxara had dragged them into an eternal nightmare, a realm where reality itself twisted and broke.

Leon knelt, struggling to keep his mind together.

Then Luna's voice came.

"Do you want more power?"

Leon exhaled sharply.

"Yes."

His Ultimate Skill Solomon, Bringer of Light and Judgment transformed.

Skill Evolution Complete → [Holy Executioner: Sol Invictus]

Leon's sword ignited, the nightmare realm cracking apart as he banished the illusions with a single swing.

Nyxara's smile disappeared.

Leon glared at her.

"This is reality. And in reality… you lose."

Kael'Zorath's body had become a walking supernova, his flames turning Dwargon into a land of fire and ash.

Gazel fell to his knees, his sword melting in his hands.

Draguel snarled, his body burning from the heat.

"Do you want more power?"

Draguel growled, his dragon instincts screaming at him.

Then—he grinned.

"Do it."

His Ultimate Skill Khaos, The Annihilator evolved.

Skill Evolution Complete → [Primordial Dragon King: Nyx-Khaos]

His body expanded, turning into a colossal dark dragon, the light around him vanishing into oblivion.

Kael'Zorath stumbled back for the first time.

Draguel smiled, showing his fangs.

"Oh? What's wrong? Not so hot anymore?"

Then he tore into the burning titan, crushing Kael'Zorath's molten heart in his jaws.

Veldora was bleeding.

For the first time in millennia, he had no arrogance left—only raw instinct.

Raza had matched him completely, his every strike devastating, his power endless.

Veldora wiped his mouth. "I'll admit… I didn't see this coming."

Luna's voice called to him.

"You are a Storm Dragon, but you could become something even greater."

Veldora grinned. "Go on."

A surge of limitless power crashed through him.

Skill Evolution Complete → [Primordial Storm Deity: Bahamut Tempest]

Veldora roared, his form expanding, his very breath creating an entire storm system.

Raza, for the first time, hesitated.

Veldora grinned. "Now we're talking."
