Marvel: Sign-In System – Starting with the Glint-Glint Fruit

The demons shrieked in terror as they flapped their wings and fled for their lives.

What they had just witnessed was beyond terrifying. They could hardly believe that humans could possess such overwhelming power—power capable of erasing and destroying everything in its path, against which they had no hope of resisting.

Even low-ranking demons were still intelligent beings. They understood self-preservation, recognized overwhelming strength, and knew what fear meant.

There was no doubt that these five Astartes could not be defeated simply by throwing greater numbers at them.

The sky quickly filled with retreating demons, but the Astartes showed no interest in pursuing them.

Those weak creatures were never the squad’s true objective.

They could also see that although the demons had fled, they had not gone very far. Instead, they hovered more than ten kilometers away, beating their wings but refusing to leave completely.

That was clearly unusual.

The reason was simple—something dangerous was hidden here.

The Astartes moved forward with heavy, deliberate steps. After advancing roughly a hundred meters, they entered another branch of the canyon.

The moment they crossed into it, dense black matter began rising from the ground. Even the purity seals attached to the shoulders of their power armor started glowing with golden flames, as though they were burning.

That reaction meant the area was saturated with an extremely powerful corrupting force.

An ordinary human entering this place would likely have their mind and body twisted almost immediately, reduced to nothing more than a puppet or slave.

“Found it,” one said.

The Astartes could sense their purity seals actively resisting the corruption. In truth, their enhanced bodies and elevated life force were already strong enough to withstand this kind of contamination on their own.

At most, it would have caused minor effects.

But this was war, and on a battlefield, the advantages provided by proper weapons and equipment could sometimes determine the outcome.

That was the purpose of military gear—to help soldiers kill the enemy efficiently and survive the battle.

The soldiers did not fear death, but if survival was possible, none of them had any reason to choose otherwise.

They would rather remain alive and continue serving the Emperor.

The five Astartes eventually stopped at the edge of an enormous abyss whose bottom could not be seen. Dust filled the air, making the surroundings hazy and difficult to see.

They looked down into the darkness below.

The squad leader did not hesitate, but instead of jumping into the abyss, he removed a cone-shaped magical device from his belt and threw it forward.

HUM!

The device stopped in midair and remained suspended above the vast opening. Magical runes carved across its surface began glowing with golden light.

A moment later, an enormous horizontal portal surrounded by sparks suddenly opened high above the abyss.

The instant the portal stabilized, the magical device vanished.

BOOM!

A massive meteor engulfed in roaring flames dropped through the portal.

Wrapped in terrifying energy, it plunged straight into the seemingly bottomless abyss as the five Astartes watched from above.

Several moments passed.

Then, the ground across millions of kilometers suddenly began to tremble violently.

Countless cracks spread in every direction as the underground structure began to collapse and convulse. Terrifying pillars of fire erupted from the dense network of fissures, while flames also burst upward from the floor of the massive crater.

An enraged roar thundered out immediately afterward.

The firelight reflected across the helmets of the Astartes’ power armor, yet despite the violent destruction around them, none of the soldiers moved.

Then, a figure shot upward through the flames inside the crater.

The Astartes immediately tracked it, raising their heads as their gazes followed it into the sky.

High above, surrounded by erupting columns of fire, the creature finally became clearly visible.

Unexpectedly, much of its body resembled that of a humanoid.

It had long limbs and a tall, unnaturally thin body. Its head looked nothing like that of an ordinary demon. A single enormous vertical eye occupied its face, while its circular mouth was filled with overlapping rows of razor-sharp teeth.

Only one wing, resembling that of a demon, extended from its back.

Overall, the creature looked grotesque and deformed.

In one hand, it carried a long, primitive-looking staff.

Burn marks covered its entire body as it opened its mouth and roared in rage and pain.

As its furious cry spread outward, time throughout the surrounding area seemed to slow dramatically.

Inside the Astartes’ helmet displays, several readings began climbing rapidly, indicating the creature’s energy level and threat rating.

Their Observation Haki gave them the same conclusion—they could clearly sense just how powerful the creature was.

There was no need for discussion.

The moment the target was identified, the squad leader tightened his grip on his battle axe as black arcs of lightning began crawling across the weapon.

With a sharp movement, he raised the axe and swung toward the creature in the sky.

BOOM!

A brilliant black-and-red flying slash erupted from the axe blade, carrying the crushing pressure of Conqueror’s Haki as it tore through the air at incredible speed.

At the same time, the other four Astartes had already moved.

They drove their feet into the ground, unleashing their immense explosive strength as they launched themselves straight into the sky.

Successive sonic booms thundered through the air behind them.

The creature roared furiously and raised its staff, sweeping it sideways to intercept the incoming slash infused with Conqueror’s Haki.

The attack exploded apart upon impact, but the tremendous force still sent the creature hurtling backward.

The four airborne Astartes reached it at precisely that moment.

A fierce aerial battle erupted immediately.

More than ten kilometers away, the countless demons that had seemingly been watching from a safe distance suddenly went berserk and charged back toward the battlefield.

The Astartes did not spare them even a glance, because high above, a Grey Knight Battle Brother had already arrived.

He wore fitted black armor beneath a hooded coat and carried no weapon.

Looking down at the demons charging from every direction, he simply formed a hand gesture and extended both arms outward.

BOOM!

Countless elaborate golden magic circles suddenly appeared across the distant ground and throughout the sky, perfectly aligned with one another.

The demons charging into the formation had no time to react before golden columns of energy erupted from the arrays.

Dense beams connected the earth and sky.

Any demon struck directly—or even grazed by one of the beams—was unable to withstand the intense heat and piercing force.

Their screams filled the air as they were reduced to ash.

Within moments, every demon rushing across the ground and through the sky had been completely erased.

Seeing this, the creature being surrounded by the Astartes let out another deafening roar.

It had finally realized how much danger it was in.

These unfamiliar humans were far too powerful.

One of them alone could fight it evenly, but against five at once, it was already beginning to lose ground.

And beyond them stood another human who had just annihilated every demon under its control in an instant.

The creature immediately used its strongest ability without hesitation.

A strange vibration spread through the air, and time itself seemed to freeze.

The creature could clearly see the Astartes suspended in midair, their weapons raised as they prepared to attack.

Its body turned into a stream of black smoke and drifted toward the Astartes holding the raised axe.

Almost playfully, it circled around him once before reaching out with one of its four-fingered hands and twisting his helmet so that he was forced to face it directly.

The vertical eye on its face slowly opened.

Its dark, corrupted pupil resembled a bottomless abyss, and the moment the Astartes looked into it, a connection formed between their minds.

The power of fear began to intensify.

That was the creature’s ability—it could briefly stop time and infinitely amplify the fear within anyone who looked directly into its eye.

As long as fear existed somewhere in a person’s heart, the terror born within their mind could inflict real damage in the physical world.

That was its greatest weapon.

But when the creature entered the Astartes’ mind, it found itself inside a vast black-and-white space.

There, it saw a small figure curled up on the ground.

It was the Astartes as a child, trapped within the memory of the most terrifying moment of his early life.

The creature grinned wickedly.

It enjoyed this process.

It loved watching its victims die at the hands of whatever they feared most.

But then it noticed something strange.

The child, who had been curled up in torn clothing, seemed to realize that someone else was there.

He slowly stood and turned toward the creature.

There was no fear in his eyes.

Only cold killing intent, as though he had just found his prey.

For the first time, the creature did not know how to react.

It watched as the child’s eyes glowed red and black-red lightning erupted around him.

Then the child began walking directly toward it.

The first step was slow, but by the second he was already running.

With every step, another burst of black-red lightning exploded around him, and his body grew larger.

He changed from a child into a teenager, then into a young man, and finally into a massive Astartes nearly two meters tall and clad in power armor.

The creature suddenly felt a surge of fear.

Its cruel grin disappeared as terror overtook its face, and it tried to turn and flee—but before it could even move, the Astartes was already upon it.

A gauntleted hand seized the creature by the throat and lifted it into the air.

Then the soldier raised his battle axe, the blade crackling with terrifying black-and-red lightning. Overwhelming Conqueror’s Haki erupted from him, carrying an unyielding, sky-shattering pressure as he brought the weapon down.

The strike shattered the mental world completely—

and at that exact same moment, reality resumed.

BOOM!

The Astartes’ axe severed the creature’s head.

Its head spun through the air, its grotesque face frozen in confusion and terror as it struggled to comprehend what had just happened.

The human clearly possessed fear.

The creature had amplified that fear, turning it into its deadliest weapon.

So why had he simply ignored it?

Why had he shattered the very fear that should have destroyed him, causing the creature’s strongest ability to fail completely?

There would be no answer.

Its life had already reached its end, and the question would die with it.

As its head continued tumbling through the air, time finally began moving normally again.

Another Astartes caught the falling head with perfect precision.

“Sector B canyon has been cleared. Target creature eliminated.”

With the battle concluded, the Astartes squad leader held the creature’s corpse and turned toward the Grey Knight Battle Brother watching from a distance. He gave him a slight nod.

The Grey Knight returned the gesture with clear respect.

He had evidently understood what had just happened.

After acknowledging the Astartes, he stepped through a newly opened portal and disappeared.

There were still other missions waiting for him.
