The sky trembled with Marcus’s relentless barrage of lightning.

  Each bolt roared down like divine punishment, vaporizing the eldritch tentacles before they could reach him.

  The Devourer’s colossal eye twitched, its massive form shuddering as if it had finally realized...

  Marcus was an anomaly.

  A being that did not conform to the natural order. And that terrified it.

  It was hesitating.

  It was… afraid.

  And yet, even as Marcus’s assault tore through its appendages, the rift in space remained open.

  It was still trying to force itself into this world.

  Just then, a flash of silver light cut through the storm as Athena appeared beside Marcus, her golden eyes sharp and unwavering.

  "I’ll handle the portal." Her voice was calm, but resolute.

  Marcus nodded. "Make sure to close it, or at the very least, prevent it from expanding."

  Athena nodded before she raised both of her hands. Immediately, the space itself began to collapse.

  A massive spatial seal formed, an intricate lattice of runes and glyphs, attempting to crush the portal shut.

  But the Devourer resisted.

  It twisted and writhed, its endless tentacles trying to force the space open.

  Then, much to Athena's surprise, it 'bled'.

  Thick, black ichor dripped from the colossal eye.

  And the moment it touched the ground—

  It shifted.

  It morphed.

  It became something else.

  A monstrous, abominable entity.

  Dozens of monstrous creature of horror, towering over the city, its entire body a mass of writhing tentacles, countless unblinking eyes, and gnashing, fanged maws.

  They shrieked.

  A sound that made reality itself warp and wail in agony.

  And then...

  They rampaged.

  Buildings crumbled, streets were torn apart, and even the barriers set by the professors began to crack.

  Thankfully, the civilians were already evacuated long ago when the invasion just began.

  Marcus clicked his tongue.

  "Tch."

  He understood.

  The Devourer wasn’t fighting him anymore. It was trying to distract him. To force him to deal with these monsters while it focused on fully entering this world.

  Marcus gritted his teeth.

  "Not happening."

  He raised his hands...

  And the storm howled in fury. Thunder coalesced around him, forming into divine spears of lightning.

  He prepared to annihilate the eldritch giants.

  But then...

  A golden radiance shone from above.

  And in the next instant, one of the abominations was erased.

  As the light faded, a figure descended.

  A woman...

  She has a long, wavy fiery orange hair and piercing blue eyes.

  Her very presence exuded divinity, a warmth that seemed to repel the unnatural taint of the Devourer.

  Marcus immediately recognized her.

  The tale has been taken without authorization; if you see it on Amazon, report the incident.

  "Jeannette le Divinia…"

  The Saintess of the Holy Church.

  One of the heroines of the novel and is part of the protagonist harem.

  She hovered above the battlefield, her golden staff glowing, her expression serene yet unwavering.

  Her eyes met Marcus’s, and she let out a small, polite smile.

  "The irregular, huh?" She muttered, having been taught in the church just how much of an anomalous existence the man before her is.

  Before Marcus could respond, a violent gale surged through the battlefield.

  A storm of fire and wind intertwined, creating a massive scorching tornado that incinerated another eldritch giant.

  From the smoke and embers, another figure emerged.

  A beautiful, mature woman, with long blue hair and piercing green eyes, wearing a purple robe while holding six foot wooden staff.

  She stepped forward, her mere presence commanding respect.

  Irene del Exterion.

  The strongest professor of Akashic Magic Academy. Although she wasn't a heroine, her little sister is. She also became the protagonist's master, allowing him to create variation of the most basic magic, allowing him to make for his lack of magical talent.

  Her emerald eyes flickered as she assessed the battlefield.

  "A troublesome situation," she murmured, adjusting the sorcerous gauntlets on her hands.

  Her gaze landed on Marcus. "It’s been a while, Miracle Child. I see you've finally stepped out of your room."

  Marcus exhaled. First the Saintess, now her.

  But there was no time for pleasantries.

  The Devourer’s colossal eye was still trying to break into this world. The monstrous horrors were still rampaging.

  This battle was far from over.

  Marcus turned back to the gaping rift in the sky. His golden eyes burned as lightning coiled all over his body.

  "Let’s end this."

  ****

  "Do you think we should make a move?" Asked Sylvia, as she observed the battle.

  "Marcus alone can handle it, but putting Irene and the Saintess pretty much guaranteed the victory. There is no need to do something unnecessary."

  "I agree. That eye is barely even a threat compared to what lays beyond. Our world needs to get used to fighting against monstrous creatures."

  "Still, I'm surprised the demons actually managed to came into contact with those creatures and even developed a spell to summon them."

  Sylvia nodded, also not expecting this development.

  "Well, let's just continue to observe."

  ****

  The battlefield burned, crackled, and raged.

  A holy radiance blazed across the sky, incinerating eldritch horrors where they stood.

  A tempest of fire and wind roared through the battlefield, tearing through the monstrous abominations.

  Jeannette, the Saintess of the Holy Church, wielded divine magic with absolute precision.

  Golden spears of light rained from the heavens, piercing through the writhing masses of eyes and maws, each spear bursting into purifying flames.

  Irene, the strongest professor of Akashic Academy, moved like a goddess of destruction, her blades of fire and wind carving through creatures that should not exist.

  The moment one of them regenerated, a second spell followed, disintegrating it before it could reform.

  The two legendary women danced through the battlefield, reducing the unspeakable horrors to ash and nothingness.

  Yet, despite their overwhelming strength, it was not enough to end the nightmare.

  Because above them, the Eye still remained.

  Athena floated in the sky, her body glowing with an aura of pure space magic.

  Her hands moved in precise, controlled motions, as if weaving the very fabric of reality.

  The rift in the sky trembled, resisting her. Trying to stay open.

  Sweat beaded on Athena’s brow.

  "This thing…" she muttered.

  Her eyes narrowed in defiance. She would not let it descend into this world.

  At this moment, high above them all, Marcus stood alone before the colossal, unblinking eye.

  It stared at him.

  He stared back.

  He could feel it. A vast, alien intelligence. A hunger that had no beginning and no end.

  In the original story, this thing was supposed to be unbeatable.

  In the later volumes of the novel, it had taken Leon, Athena, Jeannette, Irene, the professors, and an entire army of heroes to push it back.

  And even then, it had barely been repelled.

  But now…

  Marcus clenched his fist.

  His mana flared. His body crackled with untamed power.

  "If this was a battle that was supposed to take an entire army—" His golden eyes burned like molten lightning. "Then I’ll fight it alone."

  Marcus took a deep breath, and called forth the mana of the world.

  The air stilled.

  The storm halted.

  For a single instant, the world held its breath.

  Mana surged like a tidal wave, rushing towards Marcus, pulled by his sheer will.

  The sky darkened, swirling with violent purple clouds. The earth shook beneath the weight of his power.

  The professors, the students, even the strongest figures on the battlefield—

  All of them felt it.

  A force that defied reason.

  A magic beyond human limitations.

  The highest grade of magic a mage could wield.

  Ultimate Grade Magic.

  Marcus raised his hand, and whispered its name.

  "Ultimate Magic: Zorrhya El-Reika!"

  And then—

  The sky erupted.

  A storm of purple lightning descended.

  No, not just lightning, but personification of pure annihilation.

  Each bolt was not simply destructive—

  It erased.

  Reality itself fractured under the sheer force of the storm, each strike ripping away the existence of anything it touched.

  The colossal Eye trembled.

  The Devourer of Worlds, an entity that should not have been harmed by mortal magic, was being forced back.

  The storm roared, a symphony of divine eradication.

  The eldritch rift flickered, struggling to stay open. But Athena seized the moment.

  She gritted her teeth, pouring every ounce of her strength into her magic.

  Her hands moved in rapid succession, engraving countless runes into the very fabric of space.

  The rift screamed, like it was about to burst, and suddenly, it collapsed.

  The colossal eye, still writhing in pain, was dragged back into the abyss.

  The void snapped shut.

  "Finally..." Marcus took a deep breath, "It's not as easy as I thought, but it's still manageable."

  The battle…

  Was over.

  The once chaotic battlefield was eerily still. The storm above had vanished. The black blood that had turned into eldritch horrors had ceased to exist.

  The presence of the Devourer was gone.

  And all that remained—

  Was the miracle.

  The proof that a single man had rewritten defied fate.

  The students and professors, still recovering from the sheer weight of the battle, could do nothing but stare at Marcus.

  Even Jeannette and Irene, despite their experience, could not hide their astonishment.

  Marcus exhaled, lowering his hand.

  He had done it.

  He had erased something that should have been impossible to erase.

  He turned to Athena, who was wobbling in the air, looking exhausted.

  "You okay?"

  "...fine." Athena took a deep breath to stabilize herself.

  Marcus nodded, before turning his gaze back to the sky where the eye once tried to enter.

  The story have completely change, and a big boss that was supposed to appear on the later parts of the novel appeared this early.

  'Sigh, this is going to be troublesome.'
