When a God of Destruction Was Reincarnated in Tensura:

As the Demon Lords regrouped, battered but resolute, a dreadful silence blanketed the battlefield. They knew the final showdown was upon them. The sky above began to fracture, cracks spreading like a shattered mirror. A portal of swirling chaos tore through reality itself, releasing an oppressive wave of energy that seemed to choke the very air around them.

Guy Crimson: (gritting his teeth) "This power… it's suffocating. He's finally here."

Milim Nava: (smirking but tense) "This is the big bad we've been waiting for. Let's see if he can handle the wrath of Milim!"

Luminous Valentine: "That aura… it reeks of death and despair. We must tread carefully."

Leon Cromwell: (calm but focused) "Stay sharp. This isn't like anything we've faced before."

Draguel: (his fists crackling with energy) "Bring it on. Let's see how he handles true destruction."

Rimuru: (standing at the front, his aura glowing with determination) "Stay together. Don't let him break our formation. Remember, we're strongest when we fight as one."

As the portal widened, a massive surge of chaotic energy poured forth, its sheer intensity causing the ground to crumble and fissure. The weaker creatures in the vicinity dropped lifeless, unable to withstand the oppressive force. Even the strongest generals and soldiers across the battlefield felt their knees weaken under the weight of the aura.

From the portal, a figure began to descend—Artemis, the Sovereign of Ruin. His alabaster skin shimmered like polished marble, and his crimson eyes glowed with a malevolent light. Long silver hair flowed behind him like a cascade of liquid moonlight, and his obsidian armor, adorned with ancient runes, pulsed with chaotic energy. His weapon, Erebus, rested in his hand, shifting between a scythe and a spear as if alive.

Artemis: (laughing maniacally) "Mortals... insects... you've impressed me. To think you've survived this long against my creations. But now, the true end begins."

His voice echoed across the battlefield, shaking the very fabric of reality. Artemis hovered above the ground, exuding an aura of absolute dominance, as if the world itself bent to his will.

The Demon Lords stood firm, their combined auras forming a shield against Artemis's oppressive presence.

Guy Crimson: (smirking despite the tension) "You're quite the drama queen, aren't you? All this flair for an entrance."

Artemis: (grinning coldly) "Mock me while you can, Demon Lord. Soon, you'll be nothing more than ash beneath my feet."

Milim Nava: (gritting her teeth, her fists glowing with energy) "You talk big, but let's see how tough you really are!"

Luminous Valentine: (calm but deadly) "Careful, Milim. He's no ordinary foe. His aura alone is suffocating."

Leon Cromwell: (his sword glowing with radiant light) "We've faced impossible odds before. Together, we'll take him down."

Draguel: (his voice a growl) "Enough talk. Let's end this."

Rimuru: (stepping forward, his aura flaring) "Artemis, your chaos ends here. We'll protect this world, no matter what it takes."

Artemis raised Erebus, which shifted into a massive scythe, its blade radiating dark energy that distorted the space around it.

Artemis: "You think your unity will save you? I'll tear it apart. Let's see if your so-called resolve can withstand my wrath."

With a single swing of his scythe, a massive wave of chaotic energy surged toward the Demon Lords. The sheer force of the attack cracked the earth and split the sky.

Rimuru: (raising his hand) "Not so fast!"

Using Azathoth, Rimuru created a barrier of infinite density, absorbing the chaotic wave into a void of nothingness.

Rimuru: "You'll have to do better than that."

Guy Crimson: (grinning as he unleashed his power) "My turn!"

Guy activated Azazel, conjuring a storm of dark flames and ice shards that spiraled toward Artemis, threatening to encase him in an eternal abyss. Artemis countered by spinning Erebus, creating a vortex of chaos that nullified the attack.

Artemis: "Pathetic. Is that all you've got?"

Milim Nava: (charging in with fiery determination) "Think again!"

Milim activated Vritra, her body enveloped in crimson flames as she unleashed a barrage of explosive punches. Each strike created massive shockwaves, distorting the air and tearing apart the ground. Artemis dodged with inhuman speed, countering with an energy blast that sent Milim flying.

The Demon Lords worked together, launching coordinated attacks.

Leon Cromwell used Solom to summon radiant blades of light that rained down on Artemis, forcing him to dodge and defend.

Luminous Valentine activated Lilith, summoning illusions to confuse Artemis while launching devastating beams of condensed light.

Draguel unleashed Khaos, creating seismic waves that shook the battlefield and disrupted Artemis's footing.

Despite their efforts, Artemis's chaotic power seemed limitless. He shifted Erebus into a spear, using it to parry attacks with effortless precision while releasing destructive blasts of energy.

Artemis: (laughing maniacally) "Is this the best you can do? You're all insects before my power!"

He activated World Fracture, splitting the battlefield into fragmented dimensions. The Demon Lords found themselves separated, each battling against distorted versions of Artemis's energy.

Rimuru: (through Thought Communication) "Don't lose focus! Regroup and counter together!"

Using his mastery over space, Rimuru nullified the fractured dimensions, pulling everyone back together.

Rimuru: (his aura surging) "It's time we end this. Together!"

The Demon Lords unleashed their full power in unison, combining their ultimate skills into a single, devastating attack. The sky lit up with a cascade of colors as their powers merged, creating a force strong enough to shake the entire world.

Artemis, overwhelmed by the combined might of the Demon Lords, was forced to go on the defensive. For the first time, his smug grin faltered.

Artemis: (gritting his teeth) "Impossible… How can this be?!"

The combined attack struck him head-on, creating a massive explosion of light and chaos. As the dust settled, Artemis emerged, wounded but not defeated. His eyes burned with rage.

Artemis: "You've pushed me this far… but this isn't over. I'll annihilate you all!"

The battle was far from finished, but the Demon Lords had proven they could stand against the Sovereign of Ruin. The final clash was imminent, and the fate of the Cardinal World hung in the balance.
