Tokyo, October 17, 2045 – 10:30 PM
Sixteen straight hours of training at AEGIS Headquarters had drained everyone to their limits. Ren and Yuki finally returned to the apartment in a van driven by one of the AEGIS agents. The strategy for Operation Babel Tower had been finalized, and each team member had received their assigned role.
But when the van stopped in front of Ren's apartment, something strange happened.
The driver suddenly froze. His eyes widened in horror as he stared ahead. His mouth opened as if to scream—but no sound came out.
"Hey." Ren shook his shoulder. "Are you okay?"
No response.
Ren's Omniscience Ability activated instantly, scanning the surrounding area. What he discovered made alarms blare inside his mind.
A five-hundred-meter radius around the apartment was sealed by an invisible barrier. It wasn't technology from Axiom Collective—this was something entirely different. Something darker. More ancient. More… supernatural.
"Yuki, get out. Now," Ren said quickly as he opened the van door.
But when they stepped outside, the sight that greeted them made Yuki gasp.
The entire parking lot was empty. No people. No moving vehicles. Even birds and insects seemed frozen mid-motion, as if time itself had stopped. The night sky, which should have been filled with stars, was covered by swirling black clouds forming a vortex.
And in the center of the lot stood a man.
Around 185 centimeters tall, wearing a long black coat that moved despite the absence of wind. His jet-black hair fell to his shoulders, partially covering a face too pale for a normal human. His eyes glowed blood-red in the darkness, their pupils vertical like a reptile's.
But what stood out most was the aura surrounding him—waves of dark energy resembling black smoke, spiraling in dreadful patterns. Within the darkness, Ren could see shapes moving—whispering shadows that made his skin crawl.
"Ren Takatou," the man's voice echoed as if from an empty void. Cold. Emotionless. Yet terrifying. "At last, I've found you."
Ren stepped forward, positioning himself between Yuki and the stranger. "Who are you?"
The man remained silent for a moment, staring at Ren with a hollow yet intensely unsettling gaze.
"My name," he finally said in a near whisper, "is Kuro. Just Kuro."
"What do you want?"
"You," Kuro replied. "Your head. Axiom Collective has offered a generous reward to whoever delivers it."
"Bounty hunter," Ren muttered. He had expected Axiom Collective to send third parties after him—but not… whatever this being was.
His Omniscience worked overtime, analyzing Kuro. Yet something was wrong. The information came fragmented, incomplete, as though parts of Kuro's existence were inaccessible.
Half-human. Half-demon.
A hybrid existence that should not be possible.
Capable of dark magic and aura manipulation.
Threat level: EXTREME.
"Yuki," Ren whispered without turning around. "Run. Now."
"But Ren-kun—"
"RUN!"
Startled by the sharpness in his voice—something rare—Yuki slowly backed toward the apartment building.
Kuro watched her with an empty gaze. "There's no point. My barrier covers the entire area. No one enters. No one leaves until I'm finished."
"Your opponent is me," Ren said firmly. "Let her go."
"No," Kuro answered flatly. "A witness makes this more… interesting."
Without warning, he moved.
Not physically—his body melted into shadow, vanishing from where he stood and reappearing directly behind Ren. A hand wrapped in darkness lashed toward Ren's back at near-invisible speed.
Absolute Adaptive activated instantly.
Ren's body transformed in a fraction of a second. His skin hardened, his nervous system evolved to detect threats from all directions. He spun at incredible speed, grabbing Kuro's wrist just before the strike landed.
The moment they made contact, something unprecedented invaded Ren's system.
Darkness.
Not physical darkness—but something that seeped into his consciousness. Thousands of whispers clawed at his mind, dragging him toward a bottomless abyss. A cold beyond physical sensation assaulted his very spirit.
Ren released his grip and leapt back. His hand, which had touched Kuro, blackened as dark veins crawled up his arm.
"Dark magic," he muttered. Absolute Adaptive countered the corruption spreading through him. Slowly, the black faded.
Kuro's expression shifted subtly—surprise flickering across his pale face.
"You can resist my corruption," he said, faint interest in his tone. "Interesting. Very interesting."
"I won't let anyone—or anything—defeat me," Ren replied, taking his stance. "Not when millions of lives depend on me."
"Millions of lives," Kuro repeated. "A hero complex. Typical for humans with power beyond the ordinary."
The darkness around Kuro intensified. The shadows formed shapes—nightmarish creatures with too many eyes and too many mouths, all staring hungrily at Ren.
"Heroism is an illusion," Kuro continued. "In the end, everyone dies. Including you."
He raised his hand.
The shadows exploded outward. Hundreds of dark tendrils shot toward Ren, each tipped with spikes sharp enough to pierce steel.
Ren did not dodge.
Instead, he pushed Absolute Adaptive to a higher level.
His body radiated white light—pure life force evolved to counter dark magic. When the shadow tendrils struck the luminous barrier, they hissed and evaporated like water on flame.
"Light adaptation," Kuro observed. "Impressive."
Then something changed.
Kuro closed his eyes. When he opened them, the red pupils had transformed into complex, rotating symbols—ancient magic circles spinning within his gaze.
"But what if darkness isn't the only thing I control?"
His aura shifted. Still dark—but now blended with something more primal. More fundamental.
Aura manipulation.
In his right hand, darkness condensed into a sphere that devoured surrounding light. In his left, a sphere of pure white energy formed—its perfect opposite.
"Yin and Yang," he whispered. "Light and Dark. Creation and Destruction. I exist between them."
He merged the spheres.
The explosion of paradoxical energy shocked even Ren.
Light and dark fused into chaotic gray energy—both conflicting and harmonious. From it emerged beings of contradiction.
The Grey Spawn.
Creatures that simultaneously existed and did not exist. Visible and invisible. Material and immaterial.
"They cannot be defeated by conventional means," Kuro said. "Even your adaptability will struggle against paradox."
The Grey Spawn attacked.
A wolf-like monstrosity with multiple heads bit into Ren's arm, its teeth piercing his defense. A blade-winged creature rained cutting projectiles from above. Ren counterattacked, but his blows both struck and missed at the same time.
For the first time since gaining his power, Ren struggled.
Healing wounds simultaneously worsened. Reality itself defied logic.
Then—
Ren closed his eyes.
He pushed Omniscience beyond its limits.
Ignoring pain, he analyzed Kuro's magic at its core.
And he saw it.
A microscopic flaw in the magic circle within Kuro's eyes. An instability.
Half-human. Half-demon.
Not just a classification—but a weakness. Two natures locked in constant internal conflict. Human and demon battling for dominance. His magic was a manifestation of that conflict.
Ren opened his eyes and charged.
Ignoring the Grey Spawn, ignoring pain, he rushed straight toward Kuro.
Before Kuro could fully react, Ren reached him.
Absolute Adaptive evolved—not physically, but spiritually.
Ren's consciousness expanded beyond the physical realm.
When his hand touched Kuro's chest—
Soul resonance.
For a fleeting moment, their consciousness merged.
Ren saw Kuro's past. A child born of forbidden union. Rejected by both worlds. Growing in darkness. Learning magic to survive. Becoming emotionless from unbearable pain.
And Kuro saw Ren's burden. The weight of saving humanity. The fear of failure. The loneliness of overwhelming knowledge.
When the connection broke, Kuro staggered back.
"You… saw everything?"
Ren nodded. "You're not hunting me just for the bounty. You're searching for someone who understands you."
The Grey Spawn began to fade.
"Silence!" Kuro shouted, emotion finally cracking through his voice.
Darkness erupted outward, a shockwave blasting Ren back.
Yet Ren stood again.
"You don't have to fight alone," he said. "You don't have to be a monster."
"I was born one," Kuro whispered, trembling. "There is no salvation for something like me."
"There is," Ren said firmly. "Fight with me. Against Axiom Collective. Prove you're more than what the world calls you."
Kuro hesitated.
Then he shook his head.
"I'm too far gone."
His body dissolved into shadow.
"But I won't kill you today," he added before vanishing. "Call it mercy. Or weakness."
The barrier collapsed. Time resumed. The van driver gasped in confusion.
Yuki ran to Ren, tears streaming down her face.
"I'm okay," Ren assured her. "Absolute Adaptive is healing everything."
But in his heart, he knew.
There were forces beyond Axiom Collective. Forces darker and more unpredictable.
And this would not be the last time he met Kuro.
That night, as Ren lay in bed, he replayed their soul resonance.
He had seen pain in Kuro's soul.
Pain that mirrored his own.
Perhaps salvation was possible—for anyone.
Even for a half-demon lost in darkness.
Even for someone slowly losing his own humanity in pursuit of power to protect others.
The only question was—
Would they find salvation before the darkness consumed them completely?
Only time would tell.
