The moment the space around them settled, Varvatos, Velzard, Elmesia, and Diablo took several steps back, forming a wide circle that surrounded the central stage. In the middle stood Guy Crimson and Rimuru Tempest, locked in eye contact, two titanic forces of nature radiating otherworldly power.
Guy's lips curled into a devilish smirk as he let out a low breath. "I'am curious, Rimuru... Let's see if Varvatos made the right call crowning you king."
Without another word, he unleashed a portion of his aura. The air around him distorted violently as a crimson-black tempest spiraled outward. His power was demonic, chaotic, primal—like the wrath of ancient hells compressed into a single being. The ground cracked, the air screamed, and the very fabric of the empty dimension quivered.
Despite the pressure, Rimuru didn't move. His hair rustled gently in the force of Guy's released aura, but his expression remained calm. Serene, even.
Then, in his mind, Hestia's voice rang out.
[Hestia: Would you like me to analyze the battle, Master?]
[Rimuru: Yes, Hestia. Guy is the perfect opponent to test everything I've gained. Let's see what I'm really capable of.]
Suddenly, Guy vanished.
The air snapped.
BOOM!
A sonic boom exploded as the Demon lord blitzed forward, his fist aiming straight for Rimuru's head like a meteor strike. Rimuru barely managed to tilt his head aside, but the shockwave of the near miss still sent a torrent of air behind him, tearing apart trees in the distance.
BOOM!
Another strike—this time a spinning back kick. Rimuru caught the foot with his arm, but was sent flying backward through three mountains before stopping mid-air, his divine aura shielding him from the crushing impact.
Hestia's voice rang again.
"He's using no magic yet. Just raw speed, technique, and strength. Calibrating patterns—70% match to hand-to-hand form: Abyss Caliber."
"Got it," Rimuru responded, and he vanished just as Guy appeared behind him.
Their fists collided mid-air.
The shockwave cracked the skies, rupturing the heavens like glass. Thunder roared as space fractured beneath their blows. A rain of molten energy began to fall—collateral damage from their aura clashing against the atmosphere.
Guy pivoted and drew his signature longsword—Crimson Calamity—a blade forged from pure chaos and primordial fire. With a single slash, the landscape split open in a fiery rupture that surged like an erupting volcano.
"Let's see how your powers really measure up," Guy said, his voice laced with excitement.
Rimuru conjured his own blade—an ethereal construct formed from Aetherium, pulsing with starlight and cosmic wind. The two blades met in a clash that echoed through dimensions. Sparks were not sparks—they were exploding stars caught between gods.
Guy launched a flurry of strikes—diagonal slashes, feints, backstep thrusts—all precise, overwhelming, a hurricane of swordplay. Rimuru parried, stepped in, returned with circular swings and jabs. He faltered briefly—his movement not yet synchronized with the fullness of his power.
"He's overwhelming you in melee," Hestia chimed. "He uses a micro-delay after his right-hand feint. Counter with an inward step and uppercut."
Rimuru adjusted.
The next exchange was cleaner. He predicted the feint, stepped inside, and drove his elbow into Guy's ribs with such force that it echoed like a cannon. Guy stumbled, eyes flashing with admiration and bloodlust.
"Hah! Now we're getting somewhere!"
Guy raised his hand. Magic circles spun rapidly—ten layers deep, blazing with infernal energy.
"Death Streak!"
A swarm of crimson spears manifested mid-air and launched toward Rimuru, each one twisting through space like cursed javelins. Rimuru clapped his hands and cast Void Mirage, phasing through several of the attacks. Others he sliced in half or deflected with barriers composed of sacred data code.
Then Guy appeared again—fist blazing.
"Napalm Burst!"
A direct hit exploded into a sea of superheated plasma. The entire field was drowned in an inferno, the fire so intense it consumed oxygen for miles. Varvatos erected a barrier around the onlookers, shielding them from the sheer heat.
Through the smoke, a voice cut sharply.
"Impressive trick."
Rimuru emerged, his armor glowing white-blue, scorched but not weakened. His eyes gleamed with excitement. Then he moved.
This time, he was faster. He parried Guy's next sword swing and retaliated with a mid-air spin kick that shattered a nearby mountain. Guy regained balance using Spatial Motion, teleporting behind Rimuru—only for Rimuru to catch the movement.
"Nice try."
Rimuru's backhand caught Guy's jaw. The Demon King flew across the battlefield before landing, sliding across molten ground, and flipping upright. His grin widened.
"You're learning fast…"
Guy's aura surged. Crimson particles condensed around him.
"Let's stop playing then."
"Ultimate Skill: Lucifer, Lord of Pride!"
Columns of inverted light rained from above—like divine judgment, corrupted. Guy's entire body glowed with divine pride, his strength expanding into infinite levels.
Rimuru didn't back down.
He raised his hand, his own aura harmonizing with existence itself. Reality sang in resonance. His divine skill—Aetherian Sovereign—flared into view. The earth beneath him turned golden-blue. Celestial rings spun around his body, adjusting his power dynamically.
Guy blitzed forward—faster than before. Rimuru vanished, appearing behind him and striking with a magic-forged elbow that released Aether Burst—a concussive spell explosion wrapped in a physical strike.
Guy tanked it, regenerated instantly using Godspeed Regeneration, and countered with a spatial rip-slash. Rimuru dodged, then countered with a newly-created spell:
"Stellar Arcadia: Prism Spiral!"
A torrent of multicolored divine lances shot forward, homing in on Guy and tearing through his defenses. Guy summoned Material Creation: Demon Tower Shield, a massive infernal shield, blocking most—but one lance hit his shoulder and tore through it.
"Not bad," Guy growled, blood dripping.
Hestia spoke again.
"Lucifer's defenses are rigid—use fluid magic patterns. I suggest combining temporal and holy-element distortion. Creating new spell: Chrono-Lux Scatterbeam."
"Let's do it."
Rimuru raised both hands, conjuring a blinding sphere of time-warped light, which detonated into a thousand rays that fractured time itself. Guy took several hits, each one distorting his motion, briefly staggering him.
Then Rimuru pushed.
He began to dominate the rhythm. Sword and fist in perfect harmony, magic woven into each strike. Every time Guy tried to regain control, Rimuru adapted—his mastery improving by the second.
Clash.
Boom.
Crack.
The heavens above were burning, reality itself trembled from their overwhelming battle.
From the sidelines:
"Guy is getting serious. Rimuru's adapting at a terrifying pace," Diablo muttered, eyes wide.
Elmesia clenched her fist. "This isn't just a battle—it's a collision of supreme truths."
Velzard added coolly, "If they keep going like this, we might need to rebuild this continent."
Varvatos laughed. "Let them fight. This is a rare sight—two sovereigns, no restraints, testing their utmost."
Back in the air, Guy finally spoke between blows.
"You're matching me blow for blow now, Rimuru… even outpacing me in magic."
Rimuru responded with a smile.
"Not enough yet. Let's take it higher."
Their auras flared one final time.
Rimuru invoked a new spell—Aether Dominion: Trinity Collapse, a sphere of divine compression threatening to erase all substance it touched.
Guy roared, responding with Luciferian Cataclysm, a reality-cleaving sword technique wrapped in prideful divinity.
They clashed—one representing perfect divine balance, the other pure chaotic sovereignty.
The collision of Trinity Collapse and Luciferian Cataclysm tore open the sky. An explosion of light and shadow surged outward, forming a supernova-like sphere of raw power in the atmosphere. Shockwaves pulsed through the air like rolling tsunamis, distorting gravity and space across hundreds of kilometers.
The sky fractured like glass.
From below, Varvatos shielded Elmesia, Velzard, and Diablo with an enormous chaotic ether dome. The wind screamed, thunder cracked in reverse, and colors began to warp unnaturally across the sky—reality bleeding under the magnitude of divine combat.
Then… silence.
Floating amidst the crumbling clouds, both Rimuru and Guy hovered, battered but grinning. Their majestic forms flickered like unstable stars, locked into each other's rhythm, each learning, evolving.
Rimuru extended his palm.
"Dimension Flare: Eternity Collapse."
He unleashed a wave of prism-colored light that twisted through dimensions. The beam split into a tri-helix spiral, each helix imbued with time-stop, gravity implosion, and spatial inversion magic. As it tore forward, the air froze. Clouds twisted into cyclones. Parts of space simply ceased to exist.
Guy's eyes widened—but he was smiling.
"Fine. Let's break the rules."
He slammed his palms together.
"Forbidden Revelation: Demon Throne Ascension!"
A crimson gate opened behind him, from which demonic runes surged outward, spiraling into the air. From that portal, a spectral throne emerged, seated in the very concept of Chaos itself. As Guy ascended it, his aura shifted—no longer just a destructive force. It became a law of domination. His mere presence began rewriting the landscape.
Guy's hands glowed dark red as he drew an infinity sigil mid-air and summoned:
"Chaos Judgment: Reality Burn!"
A beam of infernal crimson plasma as wide as a city roared from the sky, crashing into Rimuru's attack. The impact was blinding—a collision of laws and rebellion. The resulting blast obliterated clouds globally.
And in that moment—
Rimuru vanished.
No teleportation. No motion.
He simply ceased to exist—beyond light, beyond time.
Guy's smile faded. "What?"
Then—
"Behind you."
Rimuru reappeared in 5 different places at once, striking simultaneously from all vectors with:
"Aether Phantom Style: Infinity Mirage Fist!"
Each fist carried compressed soul disintegration, bypassing normal defense and hitting Guy's core. He was thrown downward like a comet, crashing into the earth and carving a glowing scar across the continent.
BOOOOOM.
The land itself. Clouds twisted into spirals.
But Guy emerged from the crater, breathing heavily, cloak torn, one eye blazing with fire, the other with pride.
"Now that's more like it!"
He raised his hand and howled:
"All-Aspect Domain: Crimson Pandemonium!"
The entire battlefield became his. Black and red runes surged into the sky, forming a gigantic magic array—ten kilometers wide. Within it, every attack Guy thought of manifested into being. Spears of wrath. Scythes of entropy. Meteors of hate. Magic beasts born from his emotions.
He pointed at Rimuru—and they all attacked at once.
Rimuru activated:
"Primordial Rewrite: Code Override — Eternal Sovereign Protocol."
His form shifted—evolved. Rings of light formed around his wrists and shoulders. His body now generated counter-code fields, deconstructing magic before it could touch him.
The meteors warped into stardust. The attacks reversed direction.
Rimuru rushed forward, hand extended, voice calm but thunderous:
"Endless Form: Omega Judicium!"
A spear of crystallized divine law formed, layered in causality-breaking magic, moving so fast it struck before it was thrown. It passed through Guy, not damaging flesh, but hitting concept—his pride, his immortality, his throne.
Guy staggered, blood dripping from his lips—but his laughter echoed.
"You… really are something Rimuru."
He sheathed his sword.
Rimuru descended slowly, surrounded by floating magic sigils, data runes, and micro-gravitational warps. His aura pulsed with divinity and balance. Even the storm clouds cleared above him—awed.
Guy landed opposite, panting, cloak shredded.
"For the first time in millennia…" he said, cracking his neck. "I'm not just fighting. I'm feeling alive."
Rimuru smiled, his eyes glowing.
"I needed to understand how far I've come. And there's no better test than the one who once stood above all."
The dust settled. The world groaned beneath them.
From the horizon, Velzard stepped forward, clapping once. "the fight was amazing."
Elmesia, trying to catch her breath, whispered, "Was that… just sparring?"
Varvatos smiled proudly. "That was divine warfare. And neither of them even used their full power."
Guy and Rimuru stood face to face, nodding to one another.
"Next time," Guy grinned, "we fight without holding anything back."
Rimuru replied, "Agreed."
