The Silent Deity: Saiki Kusuo in Tensura

The atmosphere was electric. The moment Veldora gave the signal, both Diablo and Guy Crimson vanished from sight.

A CRACK thundered through the empty space—an aftershock from a single clash—and a gust of violent wind rolled out in all directions. Velzard instinctively raised her arm to shield her face. Her gaze snapped to Veldora, who still wore that smug grin, fingers steepled beneath his chin like a scheming overlord.

She narrowed her eyes.

"He's not even surprised," she thought. "He knew this would happen…"

Yet what bothered her more was how casually Veldora had transported them all to this realm—an endless dimension of black skies and glowing, white ground. No magic circle. No chanting. No resistance. Just a snap of his fingers and bam, they were here.

Even she couldn't do something like that without effort.

"What the hell has he become?" she whispered under her breath.

Back in the Storm Kingdom, crowds gathered at plazas, floating screens shimmering in the air as Saiki broadcasted the battle. People pointed, gasped, whispered in reverence and fear.

"Is that… Guy Crimson?"

"No way. The Demon King himself?"

"Who's he fighting?"

"That's Lord Diablo… Veldora's Right Hand."

"Look at that power... Is this real?!"

From The elite, now rehomed in the Storm Kingdom, Benimaru, Shion, Souei, Geld, and Hakuro stood with crossed arms, watching intensely. Gobta had fainted twice already. Rigurd was crying tears of joy and fear at the same time.

Back in the combat zone, Guy reappeared midair, arms crossed in an "X" over his face, skidding backward across the sky itself. Diablo landed silently like a shadow, one crimson eye gleaming, expression unreadable.

"Tch…" Guy grunted, lowering his arms. "You're faster than last time."

Diablo said nothing. He vanished again—no flash, no sound, just gone.

Guy's eyes widened. He spun—too late.

CRACK!

A fist slammed into Guy's ribs, bending him in half. The force launched him across the sky, bouncing like a comet before he righted himself and growled.

"Alright… I see how it is!"

Guy raised his hand, forming a crimson circle etched with abyssal runes. Fire and chaos coiled around him, his power bursting outward like a solar flare.

"Crimson Cataclysm: Hellsurge."

Thousands of flaming spears rained from above, twisting like snakes and burning with an unholy light.

But Diablo just… walked forward. Calm. Silent.

With each step, black ripples erased the flaming spears before they could touch him.

"Your fire is strong," Diablo finally spoke, his voice calm but sharp like polished glass. "But your understanding of power is… outdated."

He raised a finger. Snap.

A black ring expanded from beneath him, swallowing all the fire. Guy's eyes narrowed.

"Tch… what kind of ability is that? That's not just magic..."

"It's Authority, Crimson," Diablo said. "Transcendent power isn't just strength. It's truth made manifest."

And then he disappeared again.

Velzard leaned toward Veldora.

"Are you seriously letting Diablo go all out?"

Veldora chuckled, his arms spread lazily across the throne behind him.

"It's only a spar, dear sister. Besides, Crimson wanted to 'see the gap.' I'm just making sure he sees everything."

BOOM!

Diablo's foot crashed into Guy's shoulder from behind. Guy spun, throwing a flaming elbow, but Diablo blocked it with one hand—and didn't move.

"Impossible—!" Guy hissed.

He threw his arm forward, unleashing a dimensional slash of crimson energy that warped the air itself. Diablo blinked and walked through it like mist.

"No. It is inevitable."

Then Diablo responded.

He raised both hands.

The air cracked.

"Origin Devourer: Crown of Silence."

A pillar of black flame erupted beneath Guy, swallowing him whole. The crowd back in the Storm Kingdom screamed as his figure was lost in the abyss.

Benimaru clenched his fists.

"Diablo's… that strong now?"

Hakuro's eyes twitched in disbelief. "That is no longer the Diablo I trained with."

Souei said nothing, just stared with a frown.

Geld whispered under his breath.

"We're no longer at the peak… we're just watching gods."

Back to the Fight....

The flames cleared.

Guy Crimson stood, scorched, bleeding… smiling.

"Heh. This is getting fun."

His eyes ignited with demonic light. Two large, curved horns grew from his head. His wings burst open. The sky warped around him.

"Let's take this up a notch, Diablo!"

He charged.

Their fists met.

BOOM.

The world shook.

Veldora leaned forward on his throne, smirking even wider.

"Yes… show me what the pinnacle of demonkind looks like."

And Saiki? He just sipped his coffee jelly, watching like it was prime-time TV.

"yare yare...Still not enough," he muttered. "But entertaining."

Guy Crimson stood still, sweat rolling slowly down the side of his cheek—not from exhaustion, but from the pressure.

Diablo wasn't going full out.

He knew. He felt it. That eerie calm in Diablo's posture. The eerie stillness in the air, like time held its breath. Diablo was playing with him, watching him struggle like a trapped animal. It was infuriating. Humiliating.

Guy's crimson eyes narrowed. His pride—his very existence—refused to accept this.

Without hesitation, he slowly drew his God-grade sword—a blade forged at the birth of chaos itself, humming with divine energy. The instant the sword left its sheath, the air cracked with an invisible pressure. Mana roared across the battlefield like a violent hurricane.

Then came the voice:

"Lucifer: Lord of Pride… Activate."

The ground trembled. Flames of black and red spiraled around him, cloaking him in his ultimate skill—an embodiment of refined combat instinct, arrogance, and unyielding might. His muscles grew taut with strength. His eyes blazed with a cold, calculated fury. Time itself seemed to slow for him. His thoughts were racing faster than ever, calculating hundreds of possibilities per second.

He vanished.

And yet—Diablo didn't move.

No need.

Because when Guy reappeared mid-slash, poised to decapitate him—he hit nothing.

The sword swung through empty air. Again.

Again. Again.

Impossible. Where is he?!

Guy's mind was processing faster than the average god, yet Diablo's movements didn't make sense. His presence was erased—no energy signature, no aura, no fluctuation in magic. It was like Diablo didn't exist… until he attacked.

A black claw sliced Guy's cheek.

Then vanished again.

"Did you feel that?" Testarossa smirked, arms crossed as she stood beside Ultima and Carrera.

Ultima nodded slowly. "He's toying with him. Diablo hasn't even summoned a fraction of the Abyss."

"No," Carrera added, grinning wide, "He's just walking in it."

Back in the Storm Kingdom—projected by Saiki—the entire nation watched in silence. Gobta's jaw was on the floor. Hakuro held his blade with a trembling hand. Geld was sweating bullets. Benimaru was quiet, his fist clenched.

"This is… beyond understanding," Rigurd muttered. "Is that… really the Demon Lord Guy Crimson?"

Guy grit his teeth. "Stop toying with me!!" he shouted, his voice echoing like thunder through the endless void.

He spun, eyes flaring with prideful rage.

"Fight me seriously, Diablo!! I want to see the true power of the Transcendent Demons!!"

There was silence.

Then, Diablo slowly raised his head. A smirk curled on his face, elegant and terrifying.

"If I do… it won't be a fight anymore."

And just like that, the world changed.

A monstrous, abyssal aura erupted from Diablo. The dimension itself cracked as if reality could no longer hold his presence. The skies turned black. Stars vanished. The very laws of physics bent and screamed.

The ground melted beneath him, not from heat—but from sheer pressure. Diablo's energy swallowed all light. Time distorted. His body pulsed with pure chaos.

He didn't move.

But suddenly, Guy was flying backward—his chest gashed open. He hadn't even seen what hit him.

He tried to teleport—Diablo was already there.

A knee to his ribs. Bones shattered.

He raised his sword—it was gone. Diablo held it in one hand, staring at it with disinterest.

He snapped it in half.

Guy tried to speak, tried to cast a spell—but Diablo grabbed his face and whispered:

"Let me show you… the difference between pride… and the abyss."

Then it happened.

In one seamless series of movements—so fast they were almost untraceable—Diablo teleported behind Guy, struck him with a backhand that created a black hole, kicked him straight through ten dimensions, pulled him back, and impaled him with a spear made of condensed time.

Guy couldn't scream.

He tried to move—but Diablo's aura alone pinned him in place like gravity made for gods.

Blades made of shadows danced around him.

Diablo was everywhere and nowhere. His attacks defied reality. His fists carried the weight of collapsing galaxies. Every punch was a curse, every kick a law of destruction.

Guy was fast. Strong. But Diablo?

Diablo was inevitable.

He didn't attack with power—he attacked with concepts.

Guy tried one last gamble—his final technique, a crimson flame slash laced with reality distortion.

Diablo caught it between two fingers.

"Cute."

And then he unleashed Hell Seraphim: Dominion of Eternal Ruin—a technique never seen, forged in the endless void where logic dies. Diablo split the entire field into thirteen mirrored layers, each looping Guy's consciousness and body through different states of destruction.

In one, Guy burned.

In one, he froze.

In one, he fought himself—and lost.

And in the center, Diablo stood—untouched, arms open, as if welcoming him into despair.

When it ended, there was silence.

Guy's body dropped, broken and unconscious. His aura gone. His pride shattered.

And as he fell, just before the world turned black, he thought:

"So this is… the true power… of a Transcendent Demon…"

Then darkness.

Not a sound.

Diablo dusted off his cloak, turned to the others, and said calmly:

" I hope you were all entertained"

Velzard just stared, speechless. Even she—the Ice Empress—felt a chill crawl down her spine.

Back in the Storm Kingdom, the citizens couldn't speak.

Not a single one.

Saiki with the yare yare gaze...

"Well… looks like we'll need a bigger definition for 'strong'."
