Night had swallowed the city of Nirvalen whole. From the high windows of the headquarters tower, the sprawling metropolis below glittered like scattered shards of glass under a cold, indifferent moon. Inside the building, silence reigned. The usual hum of activity had long died away, leaving only the faint buzz of fluorescent lights and the occasional creak of settling architecture.
Daiki remained at his desk, buried beneath mountains of paperwork and urgent reports that had accumulated during his extended absence. His fingers moved across keyboards and documents with mechanical precision, but his mind was elsewhere—split between the mortal responsibilities of his company and the ancient, restless power coiled deep within his soul. His assistants and management team had toiled alongside him all day; now, only one remained.
Ben, his loyal assistant, slumped in a nearby chair, rubbing his bloodshot eyes. "Mr. Daiki, today was brutal. I don't think I've ever seen the workload pile up this high."
Daiki leaned back in his leather chair, exhaling slowly. The weight of exhaustion pressed against his temples, but something darker stirred beneath it—a cold, hungry presence that had become increasingly difficult to ignore. "Yeah… it was. You've done enough, Ben. Go home. It's already late. I'll finish what's left."
Ben hesitated, loyalty warring with fatigue. "But sir, this is too much. I can't just leave you here alone with all of it."
Daiki's voice remained calm, but there was an edge beneath it now. "It won't be a problem. Trust me."
After a moment of uncertain silence, Ben finally nodded. "Alright then. Let's try to wrap this up quickly."
One hour later, the office had grown quieter still. The city lights outside seemed farther away, as if the night itself was drawing closer, pressing against the glass.
Then, without warning, a cold, ancient voice echoed inside Daiki's skull.
Daiki.
It was the Second General.
What is it? Daiki replied inwardly.
There are two beings hiding in this room. Tell the human to leave. Immediately.
Daiki's posture stiffened almost imperceptibly. Who are they?
I cannot say for certain… but they are not of our kind. Their presence feels… wrong. Alien.
Understood. I'll handle it.
Daiki stood up slowly, forcing a casual tone. "Hey, Ben. I just remembered something important. You should head home now. I've got this."
"B-But sir—"
"Ben." Daiki's eyes hardened, the command clear and final. "Leave."
The assistant searched his boss's face for a moment, sensing something unspoken and dangerous in the air. Finally, he grabbed his bag. "Yes, sir. Take care."
The moment Ben stepped out and the door clicked shut behind him, Daiki moved. He locked the door with a soft, deliberate click, then slowly removed his glasses, setting them aside. The office lights flickered once, as though the building itself sensed the shift in atmosphere—a subtle change from mundane exhaustion to something far more primordial.
"You two who are hiding," Daiki said, his voice low and dangerous, "come out. Now."
Silence answered him, thick and oppressive.
Then, without warning, a razor-sharp weapon materialized from thin air and streaked straight toward his throat. Daiki tilted his head at the last possible instant. The blade kissed his cheek, drawing a thin line of blood that burned like liquid ice before the weapon dissolved into swirling black mist.
"I won't say it again," Daiki growled, his eyes narrowing into slits of cold fury. "Come out."
The shadows in the far corner of the room began to thicken unnaturally, pooling like liquid night. A deep, almost viscous darkness—black as the void between stars but veined with threads of living, pulsing gold—rippled outward. From this otherworldly shroud emerged a girl. Her face remained hidden beneath a deep hood, but strands of silver-white hair spilled forth like moonlight bleeding across fresh snow. In her grip rested a formidable blade forged from iridescent dragon scales, its edge glowing with an inner, malevolent crimson fire.
Beside her materialized a tall, imposing man. His long blonde hair was bound in a neat ponytail that cascaded down to his waist. A white cloth wrapped over his eyes, yet he moved with absolute confidence, as though he perceived the entire room—and every hidden intention within it—with perfect clarity. Delicate pointed ears peeked through his golden strands.
The girl raised her dragon-scale blade, leveling it directly at Daiki. When she spoke, the words that left her lips were utterly alien—twisted, resonant syllables that sounded like shattering glass carried on storm winds and distant thunder:
"Kael'thyrn ves'rahl… saryn'vok dae'kari!"
The blindfolded man tilted his head and responded in the same incomprehensible tongue, his voice deeper, melodic yet razor-sharp:
"En'vyr thalor… mir'kael Daiki'vess. Shor'vyn kael'dor."
Daiki's brow furrowed. He couldn't understand the words, but he could feel their power—vibrating across his skin like static electricity before a lightning strike. The Second General's voice hissed inside his mind once more, laced with rare caution.
Otherworld speech. Ancient. Extremely dangerous.
The girl took one deliberate step forward, blade unwavering. She repeated herself, slower this time, as if testing whether he was worthy of comprehension:
"Sylthar en'vyr… kael'vess Daiki?"
Nothing.
The man lifted a hand. A soft pulse of golden light bloomed from his palm, washing over them both like liquid sunlight. The air hummed with raw power. The golden threads in the girl's dark cloak brightened momentarily. When she spoke again, the same words emerged—but this time they reshaped themselves inside Daiki's mind, translating with crystal clarity, as if the meaning had been seared directly into his thoughts.
"…Can you understand us now, human?"
Her voice was eerily calm, almost polite, yet the dragon-scale blade never wavered.
The blonde man nodded once, confirming the translation spell. His blindfolded gaze seemed to pierce straight through Daiki's soul.
"We have crossed realms to find you," he declared, his words now flowing smoothly in Daiki's native tongue. "The balance has been broken. The price of becoming darkness… has already begun to echo across the veils between worlds. We must know—do you have any ties with the Ninth Shadow Monarch?"
The girl's silver-white hair shifted as she advanced another step, her hidden eyes burning with fierce intensity beneath the hood.
"Speak, Daiki. The shadow inside you… does it hunger for our world as well?"
The office lights flickered violently now. The golden threads woven through the encroaching darkness pulsed like living veins.
Daiki stared at the two intruders, his heart hammering against his ribs while the Second General remained unusually silent—watching, waiting.
"What do you mean by hunger?" Daiki replied, his voice steady despite the rising tension. "Your king is a threat to our world, and we will kill him soon enough. But for now…"
The girl's grip tightened on her weapon. In one fluid motion, she drew her blade fully into a ready stance. The man beside her did the same, his sword appearing as if summoned from light itself as he took position at her side.
"Our task is to take you down," the girl stated coldly.
"I don't know anything what you're talking about," Daiki continued, his tone darkening, "but I have a duty—a duty to protect the Ninth King. And I will do whatever it takes."
Shadow erupted from Daiki's body in a violent surge. Brilliant blue flames roared to life, illuminating the entire office in an eerie, freezing glow that cast long, menacing silhouettes across the walls. With a smooth, practiced motion, he drew his sword from its sheath, the blade singing as it came free.
The girl's hood shifted as she let out a soft, almost regretful laugh. "We could have done this the easy way… but you won't back down without a fight."
The blindfolded man adjusted his grip, the cloth over his eyes glowing faintly beneath the golden spell. "Then let the veil decide."
In the next heartbeat, the office exploded into absolute chaos.
The girl blurred forward with terrifying speed, her dragon-scale blade carving a crimson arc straight toward Daiki's neck. Simultaneously, the man attacked from the flank, his sword trailing luminous golden paths through the air like tears in reality. Daiki met them head-on, his blue-flamed shadows clashing against their gold-threaded darkness in a spectacular shower of sparks that scorched the walls and shattered the nearest window with a deafening crash.
Steel rang out like funeral bells. Shadows howled. High above the sleeping city of Nirvalen, the night sky itself seemed to fracture ever so slightly as the battle between worlds ignited in earnest.
Daiki spun with lethal grace, his sword trailing azure fire as he parried the girl's vicious strike. The impact sent a powerful shockwave rippling outward, cracking the marble floor beneath their feet. Her dragon-scale blade screamed against his own, crimson sparks colliding with blue flames in a beautiful yet terrifying dance of blood and ice.
"You protect a monster," she hissed through the translation spell, her voice tight with righteous fury. She twisted her wrist, and golden threads erupted along her blade, forcing Daiki to leap backward. The heavy desk behind him exploded into a storm of wooden splinters.
The blindfolded man was already closing in—silent, precise, and deadly. His sword swept low in a golden crescent that tore through the air with the sound of reality itself being rent apart. Daiki barely blocked it, but the sheer force lifted him momentarily off his feet and hurled him into the reinforced glass wall. Cracks spiderwebbed across the surface like breaking ice.
They're strong, the Second General said inside Daiki's head. We have to stop them.
Daiki's lips curled into a dark, feral smile. Shadows poured from his shoulders like vast wings unfurling. The blue flames roared higher, licking at the ceiling and transforming the once-professional office into a frozen inferno of otherworldly power. He charged forward.
His sword slashed in a devastating wide arc. The girl dodged, but not quickly enough—black tendrils erupted from the floor and seized her ankle, yanking her off balance. She sliced through them with a vicious curse in her native tongue, but the momentary delay gave Daiki the opening he craved.
He drove his blade straight toward the man's chest.
The blindfolded warrior didn't flinch. He raised one hand, and golden light flared brilliantly. A shimmering barrier snapped into existence. Daiki's sword rebounded off it with a deafening clang, the violent recoil vibrating painfully through his arms and shoulders.
"You carry a power General," the man said, eerily calm, as if they were still engaged in polite conversation rather than a fight to the death. "Yet you do not truly understand what you guard. The Ninth Shadow Monarch will devour this realm… and then ours. We cannot allow that."
Daiki's eyes burned with unholy fire. "Then try and stop me."
The girl recovered with cat-like agility. Her silver hair whipped wildly as she leaped onto the ceiling, defying gravity itself. From above, she rained down a relentless barrage of strikes—each one faster and more ferocious than the last—while the man pressed relentlessly from the front. Their coordination was flawless, the product of centuries of training: perfect, merciless synergy.
Daiki was driven back step by grueling step toward the broken window. Glass crunched beneath his shoes like brittle bones. A deep slash opened across his forearm; blood welled hot and immediate, hissing as blue flames cauterized it instantly in a burst of searing agony that only fueled the shadows within.
Pain only made the shadows hungrier, awakening a primal thirst that clawed at the edges of his control.
With a roar that shook the foundations of the building, Daiki slammed his palm to the ground. Black veins exploded outward across the floor, crawling up the walls and ceiling like a plague of living night. The entire office trembled violently. The girl lost her footing mid-leap and dropped like a fallen star. The man's barrier flickered under the immense pressure.
"Now!" Daiki snapped.
The Second General's power surged through him like a river of liquid night. Blue fire condensed into a massive spear of shadow and flame in Daiki's free hand, crackling with destructive potential. He hurled it straight between them with all the force of his enhanced might.
The explosion lit up the night sky outside like a second sun birthed from hell itself, a blinding azure inferno that painted the clouds in strokes of frozen fire. Windows across the headquarters building shattered in a cascading symphony of destruction. Distant alarms began to wail into the night like the cries of a dying city.
When the smoke and dust finally cleared, the two otherworlders stood back-to-back in the devastated office. Their cloaks were torn and scorched, their breathing labored, yet both remained firmly on their feet. The girl's hood had fallen back, revealing sharp, pointed ears features and eyes that glowed with the same golden threads as their magic.
The blindfolded man wiped a thin trail of blood from the corner of his mouth and smiled for the first time—cold, knowing, and utterly without mercy.
"You are stronger than the reports suggested, human. But this… this is only the beginning."
The girl raised her dragon-scale blade once more. The crimson edge now glistened with Daiki's own blood.
"We were ordered to bring you in alive," she said, voice laced with dark promise, "but if you force our hand, we will end the Ninth Monarch's pawn right here and now."
Daiki straightened to his full height, his sword dripping liquid shadow, blue flames dancing across his skin like living armor. The Second General's voice echoed within him once more.
They are strong. You must be careful.
The night wind howled through the broken windows, carrying the distant wail of sirens rising from the city far below. Cold air rushed in, mingling with the scent of scorched wood, ozone, and blood.
The battle between worlds had only just begun—and none of them would leave this ruined room unchanged.
